Return, Vegeta Comes Looking!
Even Son Goku himself did not know that, after he mastered Super Saiyan 4, the floodgates of his bloodline power had been thrown wide open, leaving the potential within his body unfathomable.
Even for someone like Old Kai, drawing out that potential came to an end after only three hours.
Although the process could have continued, any further development of his potential would have had a negligible effect, yielding even less than training on his own.
"Thank you, Old Kai." Son Goku stood up, feeling the Saiyan blood stirring within him.
Thanks to Old Kai's Potential Unleashed, the bottleneck he had sensed was showing signs of loosening.
"Hey, hey! I'm still here! If you're going to unleash your power, wait until I'm farther away!" Noticing that Son Goku looked ready to unleash his power at any moment, Old Kai flinched in fright.
The last time he had helped Son Gohan unlock his potential, he had been sent flying by these Saiyans.
With Son Gohan's example to warn him, Old Kai was extremely cautious.
Without a moment's hesitation, Old Kai hurried into the distance, keeping a relatively safe distance from Son Goku.
Seeing that Old Kai had moved far away, Son Goku activated the power of his bloodline without any reservations.
In an instant, a golden aura surged out from within him. A roiling pillar of golden light pierced the sky of the Sacred World of the Kai, and an immensely heavy aura descended upon the land.
When the golden aura dissipated, Son Goku had once again taken on the wild Super Saiyan 4 form.
After Old Kai had unlocked his potential, his Super Saiyan 4 form had been strengthened to a certain degree. Though the increase in power was not much, he had still grown stronger overall.
Upon entering the Super Saiyan 4 state again, he vaguely sensed signs of a breakthrough in the bottleneck that had troubled him for so long.
It seems that, after I entered Super Saiyan 4, Old Kai's Potential Unleashed didn't have a very noticeable effect on me.
I was too naive to think I could use Potential Unleashed to break through the current limits of Super Saiyan 4.
I still need to temper myself and increase my power in my normal state, building a solid foundation step by step before I can break through my current bottleneck.
Son Goku laid out his next plan in his mind.
Now that Old Kai had finished unlocking his potential, he would have to rely on his own training from here on.
As for the mysterious method of cultivating God Ki, he would take the initiative to cultivate it in the future and integrate it into Super Saiyan 4, to see whether it could take his Super Saiyan 4 form a step further.
Now that he had achieved his goal, there was no need for him to stay in the Sacred World of the Kai any longer.
Son Goku once again undid his Super Saiyan 4 transformation and walked slowly over to Old Kai.
"Thank you, Old Kai." Son Goku pressed his palms together and respectfully thanked Old Kai.
"It was no trouble at all. You only need to remember our agreement." Old Kai waved his hand, indicating that Son Goku need not be so formal.
"Then I'll be going, Old Kai, Supreme Kai." After bidding the two Kais farewell, Son Goku used Instant Transmission once more and left the Sacred World of the Kai.
Watching Son Goku leave, Old Kai wore a thoughtful expression. Son Goku's attitude just now had struck him as a little strange.
This Son Goku seemed to be Son Goku, yet also not Son Goku.
Perhaps I'm overthinking it. Old Kai gave it no further thought.
Earth.
Having finished unlocking his potential, Son Goku returned to Mount Paozu.
His trip to the Sacred World of the Kai had been fruitful. Not only had Old Kai unlocked his potential, but he had also obtained a method of cultivating divine power that he had never heard of before.
But Son Goku was in no hurry to cultivate God Ki. His most pressing task was to break through his current limits and take his Super Saiyan 4 form a step further.
Training, however, was not something that could be accomplished overnight.
As the saying went, time passed unnoticed in cultivation, with hundreds or thousands of years slipping by in the blink of an eye. Son Goku understood this well. Sometimes, rushing into training out of impatience would likely produce disappointing results.
Rather than deliberately seeking a breakthrough, it was better to let nature take its course. When the time came, the breakthrough would come.
Putting those thoughts aside, Son Goku went out to work the fields, driving his tiller and continuing to cultivate the land on Mount Paozu.
The scene shifted to Vegeta.
Vegeta was acting very strangely today, unlike the training fanatic he had once been.
Today, he was actually not working out in the super gravity training room.
Ever since he had broken through to Super Saiyan Third Grade a year ago, Vegeta had increased the intensity of his training, spending almost every moment in grueling workouts.
Apart from time spent eating and sleeping, he spent every day in the super gravity training room that Bulma had rebuilt.
As the prince of the Saiyans, he was naturally gifted and possessed extraordinary potential.
After a year of intense training, he had finally gained perfect control over Super Saiyan Third Grade.
Now, the time was ripe.
Vegeta looked into the distance, his immense mental perception covering the entire globe as he locked onto Son Goku's ki.
"You're finally back, Kakarot." A wicked smile appeared on Vegeta's face.
The next second, his ki erupted, and he flew at full speed toward Mount Paozu.
Back with Son Goku.
Son Goku was driving his tiller, cultivating the land on Mount Paozu.
"If only there were a faster way," Son Goku muttered helplessly.
A year ago, he had suddenly come up with the idea of cultivating the land through combat. Not only had he failed, but Chi-Chi had also scolded him, and he had not even gotten dinner that night.
Since then, he had behaved himself and could only get on with the work at hand.
That said, this quiet life had a distinctive charm for someone who had spent most of his life training.
As Son Goku drove the tiller and planned out each step of his future, he sensed Vegeta's ki approaching him at great speed.
"Huh?! That's Vegeta's ki? Why is he suddenly coming to see me?" Vegeta's sudden visit took Son Goku by surprise.
Although the two of them were friends, they did not interfere with each other and were each busy with their own lives.
Curious, Son Goku stopped the tiller and glanced into the distance.
A black speck in his field of vision grew steadily larger, until it took on Vegeta's form.
In just a few seconds, Vegeta descended in front of Son Goku at an astonishing speed.
"Kakarot, what are you... doing?" Looking at Son Goku in his work clothes, Vegeta felt that something was terribly out of place.
He had never expected Son Goku, whom he had acknowledged, to have sunk to working in the fields.
