CHAPTER 4: PUSHING LIMITS

Four months had passed since Raditz's defeat. The Lookout had been transformed into a training ground for Earth's defenders, with Kami and Mr. Popo overseeing their preparation for the coming Saiyan invasion. Each morning began before dawn with meditation, followed by grueling physical conditioning, sparring sessions, and ki control exercises that often continued until well after sunset.

Andrew stood at the edge of the Lookout, watching as Krillin and Yamcha practiced energy beam techniques under Mr. Popo's guidance. Their progress was remarkable compared to the original timeline—already, Krillin was developing a version of his Destructo Disk, while Yamcha had significantly improved his Wolf Fang Fist with added energy manipulation. Even Tien and Chiaotzu, who had joined them a week after Raditz's defeat, were advancing faster than Andrew remembered from the series.

But while the others flourished, Andrew felt himself hitting a wall.

"Still brooding?" Piccolo's deep voice came from behind him. The Namekian approached, arms crossed over his chest as always, but with a subtle difference in his demeanor. After four months of reluctant cooperation, Piccolo's hostility had gradually transformed into something approaching respect.

"Not brooding," Andrew replied, rolling his shoulders to ease the tension from the morning's training. "Just assessing."

Piccolo snorted. "You mean worrying. Your power level has barely increased in the past month while the others continue to grow."

Andrew couldn't deny it. His initial power level of 1,500—equal to Raditz in the original timeline—had only grown to around 1,850 despite his relentless training. The others were progressing at an astonishing rate, but he seemed stuck on a plateau.

"The problem," Piccolo continued, "is that you're training with fighters far below your level. There's no challenge, no push beyond your limits."

Andrew nodded grimly. "In the Time Nest, I had you and Vegeta to spar with—or versions of you, at least. Here, I'm the second strongest fighter on Earth until Goku returns."

"Second strongest?" Piccolo raised an eyebrow ridge, a hint of his old competitive spirit showing.

Andrew couldn't help but smile slightly. "For now. You're catching up quickly."

Indeed, Piccolo had made remarkable progress, his power level already approaching 1,700—considerably higher than he'd been at this point in the original timeline. The difference, Andrew suspected, was his early alliance with Kami and his focused training of Gohan, which had begun just a month after Raditz's defeat.

"The boy is showing promise," Piccolo said, seeming to read Andrew's thoughts. "His power spikes are impressive, even if he can't control them yet."

"How is his training going?" Andrew asked, genuinely curious about this altered dynamic. In the original timeline, Piccolo had been forced to train Gohan through harsh survival tactics after Goku's death. This time, the training was more structured, more deliberate.

"Better than expected," Piccolo admitted. "Chi-Chi still complains constantly, but she allows the training to continue since Goku endorsed it before leaving. I've been teaching him the basics of ki control, and his aptitude is... remarkable."

Andrew nodded. "And the Oozaru form? Any progress there?"

Piccolo's expression darkened slightly. "We've been cautious. After your warning about the transformation potential of Saiyan tails, I've only conducted that training during specific moon phases, with adequate precautions."

This was another significant change from the original timeline—preparing Gohan to control his Great Ape transformation rather than simply removing his tail. Andrew had suggested this approach, knowing that the transformation might become necessary against the Saiyans.

"At least someone's training is effective," Andrew said, looking down at his hands in frustration. "At this rate, I won't be strong enough to face Nappa, let alone Vegeta."

Piccolo studied him for a moment. "There might be another way. A method for accelerated growth."

Andrew looked up, interest piqued. "What do you mean?"

"The Ultra Divine Water," Piccolo stated. "Kept by Korin. It's said to unlock hidden potential for those who survive drinking it."

Andrew's eyes widened. He remembered this from the original Dragon Ball series—Goku had drunk it before facing King Piccolo. The water caused excruciating pain and could be fatal to those lacking sufficient strength or will, but it had indeed increased Goku's power dramatically.

"I'd forgotten about that," Andrew admitted. "But you're right... it might be exactly what I need." He straightened, a new determination filling him. "I'll speak with Korin immediately."

"One more thing," Piccolo said as Andrew prepared to depart. "Bulma has been calling the Lookout. Something about progress on a project you asked her to undertake."

Andrew nodded, his mood lifting further. If Bulma had made headway with the gravity chamber, it could provide another avenue for his training.

"Thank you, Piccolo," he said sincerely. "For the suggestion and the message."

Piccolo merely grunted in acknowledgment, but as Andrew flew from the Lookout toward Korin's Tower, he caught a glimpse of something almost like concern in the Namekian's expression.

The familiar white tower extended below the Lookout like a narrow spear piercing the clouds. Andrew descended rapidly, landing on the platform that housed Korin's sanctuary. The immortal cat was waiting, as if he'd anticipated Andrew's arrival.

"I was wondering when you'd come seeking the Ultra Divine Water," Korin said, leaning on his staff. "Been watching your training from down here. You've hit quite the wall, haven't you?"

Andrew bowed respectfully. "I need to get stronger, Master Korin. The Saiyans coming will have power levels far beyond what I can achieve through conventional training alone."

Korin nodded sagely. "The Ultra Divine Water is no shortcut. It's a test of will as much as strength. Many have died seeking its power."

"I understand the risks," Andrew replied, his determination unwavering. "But I've faced death before, and my mission is too important to let fear stop me."

Korin studied him silently for a long moment, his ancient eyes seeming to peer into Andrew's very soul. Finally, he nodded.

"Very well. Follow me."

The cat led Andrew to a hidden chamber beneath the main platform. There, in a simple stone basin, shimmered the Ultra Divine Water—clear as crystal but with an almost imperceptible blue glow.

"This water will bring pain beyond anything you've experienced," Korin warned. "It will feel as though your very cells are being torn apart and reconstructed. Only those with extraordinary will and latent potential survive the process."

Andrew approached the basin, memories of his training with Vegeta in the Time Nest flashing through his mind. The Saiyan prince had shown no mercy, had pushed him to his absolute limits and beyond. If he could survive that, he could survive this.

"I'm ready," Andrew said, kneeling beside the basin.

"One more warning," Korin added, his tone grave. "Your body is... different from others I've encountered. Not fully of this world, according to Kami. How the water will interact with your unique physiology is unknown."

Andrew hesitated only briefly. "If it can help me protect this timeline, the risk is worth it."

Without further delay, he cupped his hands, filled them with the glistening water, and drank deeply.

For a moment, nothing happened. Then, without warning, agony erupted within him.

Andrew collapsed to the stone floor, every muscle seizing as white-hot pain coursed through his veins. It felt as though his blood had been replaced with molten metal, searing him from within. He clenched his teeth to prevent himself from screaming, but couldn't stop the guttural groans that escaped his throat.

Through the haze of agony, he heard Korin's voice, distant and echoing: "Fight it, Andrew. Your will must be stronger than the pain."

Images flashed before Andrew's eyes—Chronoa sending him on this mission, his training with Piccolo and Vegeta, the battle with Raditz, the faces of the Z-fighters who were counting on him. Beyond them, he saw glimpses of the future he was trying to prevent—a devastated Earth, a fractured timeline, the collapse of causality itself.

"I... won't... fail," he gasped, forcing himself to his hands and knees despite the pain threatening to overwhelm him.

The agony intensified, reaching a crescendo that seemed impossible to endure. Andrew's vision went white, then black, his consciousness flickering like a candle in a storm. For a moment, he felt himself slipping away, the pain too great to bear.

Then, abruptly, it stopped.

Andrew sucked in a ragged breath, his entire body trembling as the pain receded like a tide, leaving him drained but somehow renewed. He pushed himself upright, surprised at how light his body felt, how clearly he could suddenly perceive everything around him.

"You survived," Korin observed, sounding mildly impressed. "And if my senses are correct, the water has had quite an effect on you."

Andrew slowly stood, feeling energy flowing through him with new intensity. His ki, once a steady current, now felt like a raging river, powerful and dynamic. He extended his hand, summoning energy, and was startled when a sphere of blue-white ki three times larger than normal materialized with minimal effort.

"Impressive," Korin nodded. "Your power level has increased substantially—perhaps even doubled. But more importantly, the water seems to have harmonized your unique energy with this world's. You're more... integrated now."

Andrew understood what the cat meant. Since arriving in this timeline, he had always felt slightly disconnected, his energy signature carrying what Kami had described as an "echo" of his original reality. Now that echo had diminished, allowing his ki to flow more naturally.

"Thank you, Master Korin," Andrew said, bowing deeply despite his lingering exhaustion.

"Don't thank me yet," Korin cautioned. "Your body needs time to adjust to this new power. Rest here tonight before returning to the Lookout."

Andrew nodded gratefully and followed Korin back to the main chamber, where the cat provided a simple meal and bedding. As he settled down to rest, Andrew concentrated on his energy, marveling at the difference. His power level had indeed increased dramatically—he estimated it now approached 3,700, more than double his previous strength.

Still not enough to match Nappa's 4,000+, let alone Vegeta's 18,000. But combined with Bulma's gravity chamber, if it was ready...

First thing tomorrow, he would visit Capsule Corporation.

Dawn found Andrew standing outside the domed buildings of Capsule Corporation, his body still tingling with his newly awakened power. He'd risen early, thanked Korin, and flown directly to West City, eager to check on Bulma's progress.

The security guards recognized him from previous visits and directed him to Bulma's private laboratory. As he approached, he could hear her animated voice followed by the sounds of tools clanging and machinery humming.

"Bulma?" he called, knocking on the half-open door.

"Andrew! Perfect timing!" Bulma emerged from behind a massive piece of equipment, her blue hair disheveled and dark smudges of grease streaking her face. Despite her disheveled appearance, her eyes sparkled with excitement. "I was just about to test the prototype! Come in, come in!"

Andrew stepped into the lab, immediately spotting the object of Bulma's enthusiasm—a large, spherical chamber constructed from a combination of Earthly materials and salvaged parts from Raditz's pod. The design was reminiscent of the gravity chamber from the series, but with notable differences that spoke to Bulma's innovative approach.

"Is that what I think it is?" Andrew asked, unable to keep the excitement from his voice.

"The Gravity Intensification Chamber? You bet!" Bulma beamed proudly. "It took some doing, especially since we couldn't recreate the exact materials from the pod, but I think I've got it working."

She led him around the chamber, pointing out various features with the enthusiasm of a child showing off a new toy. "The gravitational field is generated by these modified engines from the pod, controlled through this console here. I've set the maximum at 50 times Earth's gravity for now, though theoretically it could go higher with some refinements."

Andrew examined the chamber with admiration. In the original timeline, Bulma had only developed similar technology much later, initially for Goku's journey to Namek.

"Bulma, this is incredible," he said sincerely. "You've accomplished in months what might have taken years."

"Well, having alien tech to reverse-engineer certainly helped," she replied, wiping her hands on a rag. "Plus your communicator provided some crucial insights. Speaking of which..." She moved to a workbench and picked up several devices that resembled simplified versions of his original communicator. "I've made these for everyone. They're not as advanced as yours, but they can detect power levels and communicate across reasonable distances."

Andrew accepted one of the devices, impressed by her ingenuity. "These will give us a tactical advantage against the Saiyans. Thank you, Bulma."

"Now, about the chamber," Bulma continued, her expression turning slightly concerned. "It's ready for testing, but I should warn you—the strain on the human body at higher gravities could be dangerous without proper acclimatization."

"I understand. I'll start at lower levels and work my way up," Andrew assured her.

Bulma studied him for a moment, her scientific mind clearly noticing something different. "There's something changed about you. Your energy feels... stronger, more focused."

Andrew nodded. "I drank the Ultra Divine Water yesterday. It's increased my power significantly."

"The what now?" Bulma asked, eyebrows raised.

"A mystical water that unlocks latent potential," Andrew explained. "It nearly killed me, but the power boost was worth it."

Bulma shook her head in exasperation. "You fighters and your crazy training methods. Why can't you just use exercise equipment like normal people?"

Andrew laughed, but his expression quickly turned serious again. "Bulma, with this chamber and my increased power, I might have a chance against Nappa. But Vegeta will still be too powerful unless I can push myself even further."

"That's why I've been working on something else too," Bulma said, leading him to another part of the lab where complex blueprints were spread across a table. "You mentioned needing a spaceship capable of interstellar travel. I've been designing one based on the pod's propulsion system, combined with some of Dad's older theories about space travel."

Andrew examined the blueprints with interest. In the original timeline, Dr. Brief had modified the Namekian ship that Kami had arrived in as a child. Without that specific catalyst, Bulma was creating something entirely new.

"How soon could it be ready?" he asked, thinking of the potential need to travel to Namek if things went badly with the Saiyans.

"The design is solid, but construction would take months," Bulma admitted. "And that's assuming Dad and I work on it full-time, which we can't do while I'm finishing these for everyone." She gestured to the pile of communicators.

"The communicators take priority," Andrew agreed. "They'll help keep everyone alive during the battle. The ship is... a contingency."

Bulma gave him a penetrating look. "A contingency for what, exactly? You still haven't told me why we might need to leave Earth."

Andrew hesitated, still reluctant to reveal too much about potential futures that might now be avoided.

"Let's just say that in the original timeline, Earth wasn't the only planet with Dragon Balls," he finally said. "Having the ability to reach other worlds might become important."

Bulma's eyes widened slightly, her brilliant mind clearly connecting dots Andrew hadn't explicitly laid out. "Other planets have Dragon Balls? Like where? And why would we need—" She cut herself off, realization dawning. "Oh. If our own Dragon Balls were somehow compromised."

Andrew nodded grimly. "It's just a precaution. With the changes we've already made, we might avoid that scenario entirely."

Bulma stared at him for a long moment, then nodded decisively. "I'll prioritize the communicators, then start working on the ship designs in my spare time. In the meantime, let's get you familiar with the gravity chamber."

As she turned toward the chamber, Andrew noticed the dark circles under her eyes, partially hidden by smudges of grease and her attempts to brush her disheveled hair from her face. Looking around the lab more carefully, he spotted several empty coffee cups scattered across workstations and a small cot tucked in the corner with a rumpled blanket.

"Bulma," he said, gently catching her arm. "When was the last time you took a break? Or slept in an actual bed?"

She waved her hand dismissively. "I'm fine. This isn't my first invention marathon."

"You're telling me not to overwork myself while you've clearly been living in this lab," Andrew pointed out with a raised eyebrow. "I'm guessing for days."

Bulma opened her mouth to protest, then closed it, her shoulders slumping slightly. "Three days, actually. But it's different. I'm not the one who's going to be fighting super-powered aliens."

"No, you're just the genius creating the technology that might save all our lives," Andrew countered. "Which makes your well-being just as important as my training."

He gestured to the gravity chamber. "This is incredible work, Bulma. Something that didn't exist in this timeline for years to come. You've compressed what should have taken months or years of development into weeks. But you can't keep this pace up for the next eight months without burning out."

Bulma sighed, running a hand through her messy blue hair. "Look who's giving lectures on work-life balance," she said, but there was no bite to her tone. "The guy who just voluntarily drank potentially lethal water and wants to crush himself under extreme gravity."

"Fair point," Andrew chuckled. "How about this—I promise to train responsibly in the gravity chamber if you promise to get some actual rest. Real sleep, real food, maybe even see the sun occasionally."

Her tired eyes met his, and something passed between them—a mutual recognition of the intense pressure they were both under, albeit in different ways.

"Fine," she relented. "I'll show you how to operate the chamber, monitor your first session to make sure you don't kill yourself, and then I'll go home for a proper meal and eight hours of sleep in my actual bed."

"Deal," Andrew said with a genuine smile. "And maybe we can set up a schedule—I can train while you rest, and you can work while I recover. That way the chamber's always being used efficiently, and neither of us works ourselves to death before the Saiyans even arrive."

"That's... actually not a bad idea," Bulma admitted. "Efficient use of resources is kind of my thing."

She walked him through the chamber's operation, explaining the safety protocols and monitoring systems she'd installed. Andrew's eyes lit up as he examined the control panel, his IT background immediately recognizing the elegant solutions Bulma had implemented.

"This interface architecture is incredible," he said, running his fingers over the controls. "You've managed to integrate the alien processing systems with Earth technology in ways I wouldn't have thought possible."

Bulma beamed at his technical appreciation, clearly pleased to have someone who understood the complexity of what she'd accomplished. "The real challenge was converting their binary-like system to interface with our electronics. Their computational approach is fundamentally different—they use something closer to quantum states than our simple on-off logic."

"How did you handle the synchronization issues?" Andrew asked, genuinely fascinated. "Their systems must operate at speeds our technology can't match."

"I created a buffer system," Bulma explained, pointing to a small black box connected to the main console. "It essentially acts as a translator between the two processing architectures. The alien tech handles the complex gravitational calculations, while our systems manage the interface and safety protocols."

As they delved deeper into the technical discussion, Andrew felt a familiar excitement he hadn't experienced since before coming to this world. In his original life, technology had been his passion, his career. For a moment, he wasn't a warrior preparing for battle, but an IT professional geeking out over cutting-edge tech with a fellow enthusiast.

"I've programmed in a safety override that will automatically shut down the gravity if your vital signs drop below certain thresholds," Bulma continued, transitioning back to the practical aspects. "And there's an emergency cutoff button here." She pointed to a large red button on the control panel.

"Smart design choice," Andrew nodded. "Analog override that doesn't depend on the system staying functional. In my old job, we always built in physical fallbacks for critical systems."

"Exactly!" Bulma said, eyes bright despite her exhaustion. "You can't rely solely on software when safety is at stake. The alien pod had similar redundancies built in—they may be genocidal space conquerors, but their engineering principles are sound."

Andrew tapped his finger thoughtfully against the control panel. "Have you considered implementing a voice command system or an AI assistant? Something that could monitor conditions and provide verbal feedback during training?"

Bulma's eyebrows shot up with interest. "Like a verbal interface that could warn you when you're approaching dangerous levels?"

"Precisely," Andrew nodded, warming to the subject. "In my world, we were implementing voice-controlled systems and basic AI assistants for everything from smartphones to home automation. The scouter technology already has audio processing capabilities—we might be able to adapt that."

"That's... actually brilliant," Bulma said, already reaching for a nearby tablet to jot down notes. "I could program it to announce gravity level changes, provide real-time feedback on vital signs, and give warnings if it detects dangerous patterns. Maybe even integrate training suggestions based on performance metrics."

Andrew smiled, remembering how he'd used to set up smart systems for corporate clients. "You could even give it a personality, if you wanted. Some of my clients preferred their systems to have a bit of character—made the technology feel more accessible."

"A personality, huh?" Bulma tapped her chin with her stylus. "Like what, a drill sergeant to bark orders at you while you train?" She grinned mischievously.

"God no," Andrew laughed. "Vegeta was enough of that during my training in the Time Nest. I was thinking something more supportive—firm but encouraging."

"So more like 'Your heart rate is approaching maximum recommended levels' rather than 'WEAKLING! YOUR PATHETIC HUMAN HEART CAN'T TAKE THE PRESSURE!'" Bulma mimicked a gruff, commanding voice for the latter.

They both burst into laughter, the tension of their earlier conversation breaking.

"Exactly," Andrew said when they'd recovered. "Something that helps push limits safely, rather than mocking you for having them. Maybe with emergency protocols that can't be overridden—if certain thresholds are passed, it automatically begins reducing gravity regardless of what the user wants."

Bulma was already sketching a system architecture diagram. "I could have a basic version ready in a few days. It would make training alone much safer." She looked up at him with newfound enthusiasm. "This is why cross-disciplinary collaboration is so valuable. I was focused on the hardware and basic controls, but your IT perspective brings a whole new dimension to the user experience."

Andrew smiled at her excitement but raised an eyebrow. "And just to be clear, this isn't your permission slip for another three-day coding marathon. The AI assistant can wait until after you've had a proper night's sleep."

Bulma opened her mouth to protest, then closed it with a sheepish grin. "Caught me. My brain's already mapping out the code structure."

"I recognize the look," Andrew said, tapping the side of his head. "That 'I'll just get the framework started' expression that somehow turns into sunrise and an empty coffee pot. Been there too many times myself."

"Fine," Bulma conceded with a dramatic sigh. "But I'm at least making some notes while it's fresh in my mind. Then sleep, I promise."

"Deal," Andrew nodded. "In the meantime, let's test this impressive chamber you've already built. When can I start?"

"Now, if you want," Bulma offered. "But promise me you'll start at a reasonable level. Maybe 5G? Your body needs time to adjust, even with your impressive power boost."

Andrew nodded, though internally he was already planning to push beyond that once he'd gotten a feel for the system. Eight months remained before the Saiyans' arrival, and he needed every advantage he could get.

"One more thing before you turn yourself into a pancake," Bulma said, her tone suddenly serious. "You're pushing too hard."

"What do you mean?" Andrew asked, though he knew exactly what she meant.

"I mean you're driving yourself to exhaustion," Bulma said bluntly. "Piccolo mentioned you're training almost around the clock. Then you drink some potentially lethal water, and now you want to crush yourself under intense gravity." Her expression softened slightly. "Look, I get that you feel responsible for how all this turns out, but killing yourself before the Saiyans even arrive won't help anyone."

Andrew was taken aback by her perception and concern. In his focus on changing the timeline, he hadn't realized his determination was so transparent.

"I need to be stronger," he said simply. "In the original timeline, fighters died facing the Saiyans. Good people. I can't let that happen again."

"And it won't," Bulma assured him. "Everyone is training harder than they ever have before, thanks to your warnings. Goku is with King Kai, getting stronger than ever. Even Gohan is preparing, which wouldn't have happened without you."

She placed a hand on his arm, her touch surprisingly gentle for someone who'd spent the last several hours wielding heavy tools. "You've already changed things, Andrew. Don't forget that."

The kindness in her voice caught him off guard. For months, he'd been driven by his mission, focused solely on preparing for the Saiyans. He'd pushed aside his own well-being, his own needs, in service of creating a better timeline. Bulma's words were the first acknowledgment of the personal toll this was taking.

"I'll try to be more reasonable," he conceded, though they both knew it was a half-truth at best.

Bulma sighed, recognizing his determination. "At least let me monitor your first few sessions in the chamber. If you're going to push your limits, someone should be watching to make sure you don't go too far."

Andrew nodded his agreement, genuinely touched by her concern. "Deal. And I'll make sure you don't fall asleep at your workbench again." He gestured to the scattered coffee cups. "I'm guessing that's happened more than once."

Bulma laughed softly. "More times than I'd care to admit. Dad's found me drooling on blueprints at least twice this week."

"Not the best for the blueprints," Andrew teased.

"Waterproof paper," she countered with a small smirk, some of her usual spark returning despite her exhaustion.

As he prepared to enter the chamber for his first training session, Andrew felt a strange mix of determination and gratitude. The pressure to save this timeline remained immense, but somehow, Bulma's concern had lightened the burden. He wasn't carrying this responsibility alone anymore—all of them were sharing it, each in their own way.

"Ready?" Bulma asked from the control panel.

Andrew nodded, settling into a stable stance in the center of the chamber. "Start at 5G as you suggested. Let's see how this body handles it."

As the gravity slowly increased, pressing down on him with invisible force, Andrew focused his mind on what truly mattered—not just completing his mission, but protecting the people who were quickly becoming more than just characters to him.

They were becoming friends. Family, even. And for them, he would find the balance between pushing his limits and pushing too far.
