Chapter 21: Goku’s Rapid Growth and Healing Technique Upgrade

A month of intense training had passed, and Goku's power had skyrocketed. Through relentless practice, his combat power surged from 35,000 to an impressive 50,000. This was largely due to his creative use of the Self-Multiplication Shapeshifting technique, which allowed him to create multiple versions of himself and engage in brutal, self-driven combat. By fighting against these clones, Goku pushed his combat instincts and ki utilization to new heights, developing strategies and honing his skills in ways he had never imagined.

The clones weren't ordinary replicas—they were formidable opponents. Sometimes, Goku would even shapeshift his own form to gain advantages in battle, adding extra arms or even altering his body's composition to absorb attacks. This intense training pushed him to his limits, rapidly increasing his strength and skill.

But Goku wasn't just focusing on his physical and combat abilities. He had been diligently creating energy crystals every day, storing them away for a time when he would need to make an important upgrade. Over the month, his collection had grown to over a million crystals, and he knew exactly how he wanted to use them.

Goku opened the Super Technic Creation System, his mind focused on upgrading his Healing Palm technique. The basic-level technique had served him well, allowing him to heal minor injuries and recover from the fatigue of training. However, with the increasingly dangerous and demanding training he was putting himself through, Goku needed something more—something that could heal severe injuries quickly and efficiently.

The system responded to his thoughts, presenting him with the option to upgrade his Healing Palm technique to the intermediate level. The cost was steep: one million ki energy, a price that Goku had worked hard to be able to pay. Without hesitation, he selected the upgrade, and the system began to draw the energy from his vast store of crystals.

As the process began, Goku felt a powerful surge of energy course through him. The system was transforming the technique, refining and enhancing it in ways that would make it far more effective than before. The transformation took only moments, but Goku could feel the difference almost immediately.

His Healing Palm technique had evolved. Now at the intermediate level, it could heal nearly any injury—muscle damage, internal organ injuries, and more. The limitations were still present; it couldn't regrow limbs or restore sight to the blind, but it was far more powerful than before. Goku knew this was a life-saving technique, a critical tool in his arsenal that would allow him to survive even the most brutal battles.

With the upgrade complete, Goku tested the new technique during his next training session. He allowed one of his clones to unleash a deadly attack on him—a technique that would have left him incapacitated for days in the past. The blast hit him directly, causing severe internal damage and tearing through his muscles. But instead of retreating, Goku calmly activated his upgraded Healing Palm technique.

The effects were immediate. The pain subsided as his body began to repair itself at an astonishing rate. Torn muscles knitted back together, and damaged organs regenerated with ease. Within minutes, Goku was back on his feet, as strong as ever. He marveled at the effectiveness of the upgrade, realizing just how valuable this technique would be in the battles to come.

Goku couldn't help but feel a deep sense of satisfaction. The upgrade was exactly what he needed to continue pushing his limits. With such a powerful healing ability at his disposal, he could train even harder, experimenting with more dangerous and extreme methods without the constant worry of permanent injury.

This newfound confidence inspired Goku to increase the intensity of his training. He began to allow his clones to use even more powerful and deadly techniques against him, knowing that he could recover from nearly anything. This not only pushed his physical limits but also sharpened his mind, as he had to think quickly and adapt to the increasingly complex and dangerous scenarios he created for himself.

But Goku didn't forget about the people he cared about. After training, he would often visit Bulma and Chi-Chi, making sure to spend time with them. He knew that his strength wasn't just for himself—it was for the people he loved and wanted to protect. During one of these visits, Goku decided to show his appreciation for Bulma by giving her a special gift: his spaceship, the one he had arrived on Earth with. 

Bulma was thrilled with the gift, her eyes lighting up with excitement. The spaceship was a marvel of technology, even by her high standards, and she couldn't wait to start studying it. She hugged Goku tightly, grateful for the thoughtful gesture, and Goku couldn't help but smile at her reaction. He knew she would make the most of it, and it made him happy to see her so excited.

Goku also took the time to teach Bulma and Chi-Chi the basic Breathing Technique, the same one that had been so instrumental in his own growth. He knew that they might never reach his level of power, but with this technique, they could at least become stronger and better able to protect themselves. Both Bulma and Chi-Chi were eager to learn, and Goku was patient as he guided them through the process.

As the days went by, Goku continued to train, but with a renewed sense of purpose. His strength was growing rapidly, but he knew that power alone wasn't enough. He was becoming more strategic, more thoughtful about how he used his abilities. The upgrade to his Healing 

After a month of intense training, Goku's strength had skyrocketed. His combat power had increased from 35,000 to an impressive 50,000. This rapid growth wasn't just from fighting; Goku had made great use of his shapeshifting techniques, particularly the Self-Multiplication Shapeshifting. He created multiple versions of himself, engaging in fierce battles to sharpen his instincts and improve his ki utilization.

The training was grueling but effective. Goku pushed his limits by transforming his body during combat, such as changing from two arms to six, or even altering his form to evade critical attacks. At times, he turned into a rubbery form to absorb blows or adapted his body to surprise his clones. His adaptability was key to his rapid development.

As Goku continued creating energy crystals during his downtime, he amassed a significant amount of energy. He now had over one million energy crystals at his disposal, and he knew exactly how to use them. Without hesitation, Goku accessed his Super Technic Creation System and upgraded his Healing Palm technique from basic to intermediate.

The upgrade was significant. The newly enhanced Healing Palm could now heal any physical damage, from muscle tears to severe internal organ damage. However, it couldn't regrow lost limbs or restore sight to those born blind. The technique was a powerful life-saving card, and Goku felt a surge of confidence knowing he had it in his arsenal. With this, he could push his training even harder, knowing he had the means to recover from the most intense injuries.

Satisfied with his progress, Goku decided it was time to visit Bulma. He had been regularly meeting her, keeping their bond strong. But this time, he had more than just a casual visit in mind. He arrived at Capsule Corporation and found Bulma in her lab, surrounded by her various projects.

"Hey, Bulma!" Goku greeted her with his usual enthusiasm. "How's the spaceship research coming along?"

Bulma looked up from her work, her eyes lighting up at the sight of Goku. "Oh, Goku! I'm glad you came by. The spaceship you gave me has been incredible to study. I've made a lot of progress. The technology is way ahead of what we have on Earth, but I'm getting closer to understanding how it all works. I think I can start working on some upgrades soon."

Goku smiled, happy to hear that his gift was being put to good use. "That's awesome, Bulma! You're the best. I was also wondering if you could help me with something else."

"Sure, what is it?" Bulma asked, intrigued.

"I was thinking about my training and how I can make it even tougher. Do you think you could build me a gravity belt? Something that can increase gravity around me while I train?"

Bulma considered the idea for a moment. "A gravity belt, huh? That's an interesting concept. It would definitely make your training more challenging. I could design it to let you adjust the gravity levels, so you can keep pushing yourself as you get stronger."

"Exactly!" Goku nodded eagerly. "I want to be ready for anything. With stronger gravity, my body will adapt faster, and I'll get even stronger."

"Leave it to me," Bulma said confidently. "I'll start working on the design right away. But remember, Goku, you need to be careful with this kind of training. Too much gravity can be dangerous if you're not prepared."

"I know," Goku replied. "But I have to keep getting stronger. I can't afford to slow down."

Bulma smiled at his determination. "You really are something else, Goku. I'll get the gravity belt done as soon as I can."

Goku thanked her and left Capsule Corporation with a renewed sense of purpose. With the Healing Palm technique now upgraded and the prospect of even more intense training with the gravity belt, he felt unstoppable. The future held many challenges, but Goku was ready to face them head-on.

As he returned to Grandpa Gohan's home, Goku couldn't help but feel a sense of accomplishment. His training was yielding results, and with Bulma's help, he was on track to becoming even stronger. The journey ahead was long, but with each step, Goku was getting closer to his goal of being the strongest fighter in the universe.
