Kaioken, Achieved! [Written while slacking off, please give votes and collections~!]

This aura could not be too strong, or it would cause the energy points to run wild. It could not be too weak either, or it would have no effect at all.

So this required the user to have sufficient understanding of their own body and powerful mental control.

Because controlling the amount and shape of that ki did indeed require a certain level of mental cultivation.

Whoosh—! Pfft!

Just as Son Gohan was trying to control his own ki, a burst of air rang out beside his ear. He opened his eyes and saw Raditz's aura erupt around him. His face flushed red, and he spat out a mouthful of blood.

The muscles all over his body began to swell and deform irregularly, and pained groans escaped his mouth.

One had to know that even a Saiyan, someone who fought on alien planets day after day and was used to living on the edge of a blade, could not endure this pain. That was enough to show how intense it was.

In Son Gohan's senses, Raditz's aura began to grow incomparably chaotic, like an ocean caught in a raging storm.

Clearly, Raditz had been careless, lost control, and suffered internal injuries.

Seeing this from the side, Son Goku immediately got up and came behind Raditz, placing a hand on his back.

After the aura around his body began to surge, it transformed into a hazy white light and slowly flowed into Raditz's body.

Raditz's pale complexion slowly regained some color, and with Son Goku's help, the aura around him also began to calm down.

Only after taking several deep breaths did Raditz open his eyes. His eyeballs were covered in a frightening number of blood vessels, making him look somewhat terrifying.

The aura around him had also become weak, as if he had suffered fairly serious internal injuries.

But at least he was all right, which made Son Goku let out a sigh of relief.

"Sorry. I was too impulsive just now. Thank you, Kakarot," Raditz said, thanking Son Goku.

"No big deal." Goku waved a hand and leaned off to the side.

In truth, Son Goku had also been preparing to start activating the energy points inside his body just now. He had not expected Raditz to take the first step before him, only for such a major mistake to happen.

Son Gohan took out half a Senzu Bean from his pocket and tossed it toward Raditz with a flick of his hand.

"Swallow it. It can heal your injuries."

Smack.

Raditz reached out and caught it. Without any suspicion, he put it straight into his mouth, chewed, and swallowed it.

The next moment, the blood vessels in his eyes immediately faded. After that, the originally weakened aura around him also recovered rapidly.

In less than ten minutes, Raditz had returned to almost peak condition, his previous pale complexion completely gone.

This was only the effect of half a Senzu Bean. If it had been a whole one, he would have recovered within a second after swallowing it, but that would have been too wasteful.

"Be more careful next time. Don't act recklessly," Son Gohan warned.

"I know." Raditz nodded.

And he noticed that Raditz's aura had not only recovered, but had become even larger than before.

Sure enough, as long as Saiyans are injured or brought to the brink of death, their strength will improve to a certain extent after they recover. The more serious the injury, the greater the increase.

In truth, Son Gohan was not interested in this. First of all, this thing still required serious injury or even near-death to obtain the effect.

If one did not rely on Senzu Beans or those high-tech healing pods, once seriously injured or on the verge of death, they might truly face the danger of dying.

Although this world had Dragon Balls that could revive people, Son Gohan still did not like the idea of trying that kind of feeling.

And if things went the way they had with Vegeta that time—wounding himself heavily only to have no one willing to help him—the result would be truly miserable...

Son Gohan was more willing to believe in constantly cultivating to grow stronger, deepening and further excavating his own potential. That was what he should be doing, not resorting to opportunistic shortcuts like this to become stronger.

With Raditz serving as a warning, the other two became even more cautious.

After that, Son Gohan reentered his cultivation state. He had long since made thorough preparations, so he did not need to worry about those things.

The first strand of ki slowly approached the energy point. Under Son Gohan's control, it decisively poured into the energy point.

Whoosh—!

The instant the ki entered the energy point, the originally calm, flowing ki suddenly erupted.

Crack!

In the outside world, Son Gohan's right-arm muscles suddenly bulged up, becoming more than twice as thick as before.

The three people around him naturally sensed Son Gohan's change. Son Goku's eyes narrowed slightly, and he flashed directly behind his son, ready to act at any moment.

But in the next moment, although Son Gohan's aura was somewhat chaotic, it quickly calmed down again. At the same time, his thickened right arm swiftly returned to its original state.

Inside Son Gohan's body, the originally extremely disordered airflow could be seen immediately returning to its original order under his powerful mental and spiritual control.

This was like controlling troops in ancient times. Your mental and spiritual cultivation was your prestige. When your prestige was strong enough, with just one roar, even thousands or tens of thousands of people would immediately quiet down and listen to your command.

Very soon, under Son Goku's gaze, Son Gohan's other arm, both feet, and the muscles of his body all began to deform and bulge, but they quickly returned to their original state.

Son Goku nodded, then sat back down in his original spot.

After an unknown amount of time, Son Gohan suddenly opened his eyes and stood up. The aura around him had become far richer and more condensed than before.

"You succeeded?" Son Goku asked.

"Yes, Father." Son Gohan nodded to Son Goku.

"Let me see," Son Goku said curiously. The two people nearby also opened their eyes and looked at Son Gohan.

Son Gohan nodded, took his stance, and prepared to use the Kaioken.

That was right. Son Gohan had already learned the Kaioken. The energy points throughout his body had all been stimulated and brought under his control; the only thing left now was to stimulate all those energy points at the same time.

The only difficulty was how to simultaneously control the tremendous energy that erupted once those energy points were stimulated.

Taking a deep breath, Son Gohan suddenly let out a shout. The qi he had prepared long ago poured directly into the energy points, and in that instant, the qi throughout his body erupted with incomparably fierce power.

Boom~!

With Son Gohan at the center, a mighty aura exploded outward, whipping up a powerful current of air that swept in every direction.

Red light burned up from Son Gohan's body, surrounding him like a blaze of flame, and an aura more than twice as strong as before poured out.

Son Goku, Piccolo, and Raditz were all stunned. Before, they had thought North Kai's claim that it could multiply one's strength was nothing but bragging.

If this secret technique could increase one's strength by even half, it could already be called unbelievably powerful.

And at that moment, Son Gohan was incredibly excited. He had finally learned one of the bug-level techniques of the Dragon Ball world—the Kaioken!

The powerful energy flowing through his body filled Son Gohan with an overwhelming confidence!
