After eating and resting for a night, the next day, King Kai kept his promise and began formally teaching Yuujin and the others the methods to cultivate the Kaio-ken technique.
As for the Spirit Bomb, according to King Kai, if Yuujin and the others couldn't even master Kaio-ken, then they shouldn't even think about learning the Spirit Bomb.
As a powerful martial art, training in Kaio-ken was naturally rigorous and complex. It was similar to when Master Roshi taught Yuujin and the others the Kamehameha;
it wasn't as simple as just putting your hands together and pushing them forward. There were many techniques for circulating, guiding, and gathering energy, and one mistake could lead you astray and drastically reduce the power.
Moreover, unlike the Kamehameha, which focused on gathering and enhancing energy, Kaio-ken required the practitioner to perfectly integrate their energy with their body, using it to maximize their physical potential.
True Kaio-ken was not just about a temporary energy boost; it was about comprehensively improving all attributes such as strength, speed, attack power, and defense during battle!
King Kai spent an entire day explaining the training methods for Kaio-ken. Yuujin and Chi-Chi managed to absorb the information, albeit with some mental exhaustion, while Goku was already nodding off midway through the lesson.
After explaining the methods, it was time for actual training, and it was then that Yuujin truly experienced how painful it was to practice Kaio-ken.
Even though Yuujin had already reached an advanced level in Ki control, it was still inevitable to make mistakes when guiding energy through the complex pathways in his body for the first time.
The consequences of these mistakes were damaged meridians, ruptured blood vessels, and, in severe cases, the out-of-control energy could even tear and crush fragile internal organs!
Yuujin and Chi-Chi vomited blood countless times during Kaio-ken training. Fortunately, Yuujin had plenty of senzu beans on hand to quickly recover; otherwise, they might have ended up killing themselves before mastering Kaio-ken.
Compared to Yuujin and Chi-Chi's struggle, Goku, who had been dozing off during the lesson, made rapid progress. Although she occasionally suffered from energy disruptions that injured her, she was still doing far better than Yuujin and Chi-Chi.
Goku was the type who learned through physical memory. She didn't understand theoretical explanations, but once shown how to do something, she picked it up quickly.
Yuujin couldn't help but reflect that it was no wonder that in the original Dragon Ball story, only the protagonist, Son Goku, managed to learn Kaio-ken. Piccolo, Tien Shinhan, and others who had also trained on King Kai's planet didn't seem to master it.
Kaio-ken was indeed a powerful martial art, but it wasn't something that just anyone could learn!
Despite feeling a bit disheartened, this also fueled Yuujin's competitive spirit. He had plenty of senzu beans; even if it took hundreds or thousands of attempts, he was determined to master Kaio-ken!
Days and months alternated, and the seasons changed from winter to spring. Amidst the painful yet fulfilling training, a whole year had passed since Yuujin and his companions arrived on King Kai's planet.
Meanwhile, on Earth, in West City—
In the Dragon Ball world, although West City wasn't a popular tourist destination or a government capital, it was still a well-known city because the famous Capsule Corporation was based there.
Capsule Corporation, founded by Dr. Brief, was a private company that not only made life more convenient with its capsules but also significantly advanced human civilization. The vast revenue generated from selling capsules made Dr. Brief's family the wealthiest in the world.
However, aside from Capsule Corporation, another company had been established in West City over the past year, rapidly rising to fame—
Dragon Ball Corporation!
Without a doubt, Dragon Ball Corporation was founded by Yuujin, with Bulma, Tights.
Yuujin's ambitions weren't confined to the small planet Earth; he aimed for the vast expanse of the universe. Conquering the cosmos required not only personal strength but also substantial logistical support.
Even if you were invincible in the universe, how could you manage the entire cosmos alone? Even the tyrant Frieza had subordinates to help him with errands and chores, so why wouldn't Yuujin need the same? Dragon Ball Corporation was the organization Yuujin was preparing for that purpose.
For now, the company would accumulate massive financial and material resources under its name, and once Yuujin's strength was sufficient, he could begin recruiting soldiers and set out to conquer the universe!
Back when he was training on Planet Vegeta and venturing into space, Yuujin deliberately collected various alien technologies. Before heading to King Kai's planet, he handed all these technologies over to Bulma for development. If utilized properly, these alien technologies could easily push Earth's civilization forward by decades!
While Yuujin, Goku, and the others trained on King Kai's planet for a year, Bulma and Tights were far from being idle. Following Yuujin's instructions, they founded Dragon Ball Corporation in West City and rapidly grew the company using the alien technologies Yuujin had left behind. In just a year, the company had already reached a level comparable to Capsule Corporation, astonishing many people.
Notably, Dragon Ball Corporation's headquarters was located right across from Capsule Corporation, housed in a towering skyscraper hundreds of stories high, with a spiraling Shenron and seven Dragon Balls as its emblem.
On this day, a fleet of black cars stopped in front of Dragon Ball Corporation's headquarters. Several attendants opened the doors, and Bulma and Tights stepped out one after another.
Bulma and Tights, had undergone significant transformations. The sisters were dressed in black office attire with high heels and stockings, exuding a cold, distant beauty.
As soon as the women stepped out of the cars, a swarm of waiting reporters, like cats catching the scent of fish, eagerly rushed toward them—
"Miss Bulma, Miss Tights, may we have an interview?"
"Dragon Ball Corporation has become a world-renowned leading enterprise in less than a year, launching several groundbreaking technological products. What is the secret to your company's success?"
"It's said that Miss Bulma and Miss Tights are only vice presidents of Dragon Ball Corporation. Who exactly is the mysterious president?"
"Since you're Dr. Brief's daughters, did he support the founding of Dragon Ball Corporation?"
"And also..."
