Yajirobe made his way back to the training area, where Goku and Mr. Popo were deep in their practice. Goku's brow was furrowed in concentration as he faced off against the clay copy of himself, his movements quick and fluid as he attempted to find a way to defeat his seemingly elusive opponent.

Yajirobe watched for a moment, taking in the scene. Goku's frustration was evident, his determination to overcome this challenge unwavering. Beside him, Mr. Popo stood with an air of calm authority, his presence a guiding force in Goku's training.

"Hey, Goku!" Yajirobe called out, catching the young warrior's attention. "Having some trouble there?"

Goku turned toward Yajirobe, a mixture of exhaustion and determination in his eyes. "Yeah, Yajirobe. This copy of me is tough. I keep wasting so much energy trying to hit it, and I can't seem to land a clean hit."

Yajirobe nodded in understanding, his own experience as a fighter allowing him to empathize with Goku's struggle. "I get it. It's frustrating, but you know what they say – sometimes, it's not just about brute strength. You've got to use your head."

Goku's eyes lit up with realization, his determination reigniting. "You're right, Yajirobe. I've been going at it the wrong way. I need to find a strategy, a way to outsmart my opponent."

Mr. Popo's voice interjected, his tone filled with wisdom. "Indeed, Goku. Training is not just about physical strength, but also about honing your mind and instincts."

Yajirobe's lips curled into a smirk. "Listen to the wise man, Goku. He knows what he's talking about."

Goku grinned, a newfound determination burning in his eyes. "Thanks, Yajirobe. Mr. Popo, I'm going to try a different approach. I'll use my energy more efficiently and find a way to defeat this copy."

Mr. Popo nodded in approval, a small smile playing on his lips. "Very well, Goku. Remember, the key is not just power, but precision."

As Goku returned to his training, Yajirobe turned to Mr. Popo. "Kami and I had a talk. We're going to start preparing for the 23rd tournament right away."

Mr. Popo's gaze remained fixed on Goku, his voice calm but assuring. "A wise decision. The tournament will serve as both a test of your progress and a way to focus your training. It is a step toward the battles that await."

Yajirobe nodded, a sense of purpose settling within him. "Exactly. And there's something else – we discussed the androids, the ones from the Red Ribbon Army. Kami and I know they're a threat. We need to find a way to stop them before it's too late."

Mr. Popo's expression grew serious, his gaze meeting Yajirobe's with a solemn understanding. "The androids... a formidable challenge. But with Kami's guidance and your determination, we will face it together."

Yajirobe watched Goku's focused training, his mind turning over the weight of the knowledge he possessed. As Goku continued to practice against the clay copy of himself, Yajirobe felt a deep urge to share something important with his friend. He took a deep breath, approaching Goku with a determined expression.

"Hey, Goku," Yajirobe began, his voice gentle yet serious. "I've got something I want to talk to you about."

Goku paused mid-movement, turning his attention to Yajirobe. "Sure thing, Yajirobe. What's up?"

Yajirobe hesitated for a moment, choosing his words carefully. "Goku, you're not just an Earthling. You're from a race of warriors called Saiyans. They're aliens, and they're known for their fighting abilities."

Goku's brow furrowed, his expression a mix of surprise and curiosity. "Saiyans? Aliens? I've never heard of them before."

Yajirobe nodded, his gaze unwavering as he continued. "Yeah, it's a lot to take in, I know. But I want you to know that this doesn't change who you are. You're still the same good-hearted person I've known all this time. Your origins might be different, but you're still Goku."

Goku's eyes held a mixture of contemplation and gratitude. "Thanks, Yajirobe. I appreciate you telling me this. But you know, whether I'm from Earth or from another planet, I'm still me. I'm going to keep training, keep fighting for what's right."

Yajirobe's heart warmed at Goku's response, his respect for his friend deepening. "Exactly, Goku. That's why I wanted to tell you. Your strength, your spirit – it's what makes you who you are, no matter where you're from."

Goku's grin widened, a determined spark in his eyes. "Thanks for having my back, Yajirobe. Now, let's see if I can put this new information to good use against this clay copy!"

Yajirobe observed as Goku continued his intense battle against the clay doll, a renewed focus and determination evident in his every move. The once elusive opponent seemed to have met its match, as Goku's strikes grew more precise and calculated. Yajirobe couldn't help but be impressed by Goku's ability to adapt and overcome, his unwavering spirit shining through even in the midst of training.

As Goku landed a decisive blow, shattering the clay doll into pieces, Yajirobe couldn't help but offer a hearty applause. "Nice one, Goku! You really nailed it!"

Goku grinned, wiping sweat from his brow. "Thanks, Yajirobe! It took some thinking, but I finally figured out how to hit it just right."

Yajirobe chuckled, a sense of admiration filling his words. "You know, Goku, you've got a knack for that – taking on challenges and finding a way to beat them. It's one of the things I've always admired about you."

Goku's smile widened, a genuine sense of pride in his accomplishments. "Well, I guess I just like pushing myself to be better. Plus, training is always fun!"

Yajirobe's gaze grew more thoughtful, his mind wandering to the future that had driven him to this moment. He couldn't help but wonder about the impact of Goku's survival from the heart virus. Would it have made a difference in the grim future he knew? Would they have still faced the same challenges and threats?

As Goku caught his breath, Yajirobe's voice held a tinge of introspection. "Goku, I've been thinking. If you hadn't died from that heart virus, do you think we would have been able to change the future? Or were the androids and all that still inevitable?"

Goku's expression grew contemplative, his gaze fixed on the horizon. "It's hard to say for sure, Yajirobe. But I believe that no matter what challenges come our way, we'll always find a way to fight and protect our world. As long as we're together, we can face anything."

Yajirobe's heart swelled with a mixture of hope and determination. Goku's words resonated deeply, reaffirming their bond and shared commitment to shaping their destiny.

"You're right, Goku. We'll face whatever comes our way, together," Yajirobe replied, his voice firm and resolute.

Goku turned to Yajirobe with a knowing smile, a sense of understanding passing between them. "Hey, Yajirobe, there's something I've been meaning to ask you. You said you're from the future, right? Is there something you're not telling me?"

Yajirobe met Goku's gaze, a mixture of surprise and resolve in his eyes. He took a deep breath, his heart pounding as he made a decision. "Yeah, Goku. I am from the future. There's a lot I need to tell you, about the androids, about what's to come. But I know I can trust you with this."

Goku's eyes held a mixture of curiosity and reassurance. "You can always count on me, Yajirobe. Whatever it is, we'll face it together."

As their conversation continued, the chapter ended, leaving the readers with a sense of unity and anticipation. Yajirobe's decision to share the truth with Goku marked a significant turning point in their journey, as they faced the challenges of the present and the uncertainties of the future hand in hand, ready to confront whatever lay ahead.

Over the next three years, Yajirobe and Goku immersed themselves in rigorous training, their determination and resolve burning brighter than ever before. Yajirobe, fueled by a newfound sense of purpose, pushed himself to his limits and beyond, shedding the extra weight he had carried for so long. His body grew leaner and more defined, a testament to the intense effort he had poured into his training.

Goku, too, continued to push himself to new heights, honing his skills and mastering his techniques with unwavering dedication. The bond between Yajirobe and Goku deepened as they trained side by side, spurring each other on to greater heights. Their camaraderie was evident in every clash, every spar, and every shared moment of exhaustion.

As the day of the 23rd World Martial Arts Tournament approached, Yajirobe felt a sense of anticipation mixed with nerves. The battles that lay ahead would be a culmination of their efforts, a chance to prove their growth and readiness to face whatever challenges awaited them. Yajirobe's once-pudgy exterior had transformed into a lean and powerful physique, a testament to the relentless training regimen he had embraced.

Kami, ever watchful, scanned the horizon for any signs of the looming threat posed by the Red Ribbon Army and the androids. Yet, despite his vigilance, no leads or information surfaced during the three years of preparation. The absence of concrete information left a lingering sense of uncertainty, a reminder that the challenges they faced were far from over.

As the day of the tournament arrived, Yajirobe and Goku stood side by side, their eyes fixed on the arena before them. The excitement in the air was palpable, the crowd buzzing with anticipation. Yajirobe was as ready as he would ever be. He exchanged a determined glance with Goku, their shared resolve unspoken yet understood.
