After Son Goku and Lazuli finished eating, they went back to enjoying their time alone together.
Later, Bulma and Chi-Chi joined them.
The next day, Lazuli asked Son Goku, "Goku, do you have unlimited stamina too?"
Son Goku said, "Since you asked, I won't hide it anymore. I'll come clean. I made a wish to Shenron before and gained unlimited stamina."
"So that's how it is," Lazuli said.
Son Goku smiled without saying anything.
Then the two got up, left the bedroom, closed the door, and went to the dining room to eat.
After their meal, they went to the Gravity Room to watch everyone train.
Seeing them arrive, Lapis said to Son Goku, "Brother-in-law, your Gravity Room really helps with training. I've only spent a day here, and I already feel a lot stronger."
"Of course," Son Goku said. "The Gravity Room deserves a lot of credit for everyone's current strength. Keep training hard, and you'll catch up."
Lapis nodded. Son Goku pointed at him and transmitted the Kaioken training method to him from a distance.
Then he told Lapis, "What I just taught you is Kaioken. Combine it with training in the Gravity Room, and your strength will grow even faster."
After learning about Kaioken's remarkable effects, Lapis said to Son Goku, "To think a technique this amazing exists! I'll train hard, brother-in-law, and do my best to get stronger as quickly as possible."
Son Goku nodded, then left with Lazuli.
Afterward, the two returned to the bedroom to rest.
The next day, Trunks emerged from the Hyperbolic Time Chamber and found Son Goku. He said he had mastered the Super Saiyan 4 transformation and could now transform whenever he wanted.
Son Goku praised Trunks's extraordinary talent. Trunks scratched his head and said modestly, "It's all thanks to your teaching, Uncle Goku. Otherwise, I could never have become this strong."
Son Goku said, "A teacher can show you the way, but the training is up to you. Your strength owes more to your talent and hard work. My guidance certainly helped, but I can't take all the credit."
Trunks nodded, then said goodbye to Son Goku, ready to return to his own world.
Hearing this, Son Goku called everyone out of the Gravity Room to see Trunks off.
As everyone waved goodbye, Trunks climbed into the Time Machine and returned to his own world.
After seeing Trunks off, Son Goku continued resting, and that night, he once again enjoyed the company of his three women.
These days continued for an entire week.
Only then did Son Goku resume his training, and all three women breathed a sigh of relief.
Son Goku used Instant Transmission to reach the Red Giant where he had trained before and resumed his previous training.
With Son Goku's current strength, the immense gravity on the Red Giant no longer affected him at all.
It was nothing like when he first arrived, when gravity ten million times that of Earth had left him barely able to move, its tearing pull on his body twisting his face in pain.
Now Son Goku could train freely on the Red Giant, no longer struggling as he had at first.
Though he still had a Super Saiyan 4 body, Son Goku was confident that even if he stood still and let Prince Vegeta attack him at full power as a Super Saiyan 2-or even a Super Saiyan 3-Vegeta probably wouldn't be able to hurt him in the slightest.
A Super Saiyan 4 body was already incredibly tough, and Son Goku had tempered his further under gravity ten million times that of Earth.
Calling his current body indestructible would be no exaggeration. Son Goku didn't believe any laser gun could injure him.
Even without the protection of his ki, even while relaxed, a mere laser gun couldn't hurt Son Goku. It wouldn't even qualify as a tickle.
And so Son Goku and the others returned to their simple, unremarkable, and tedious lives of training.
Half a month later, Bulma, Chi-Chi, and Lazuli shared some wonderful news: all three were pregnant.
Son Goku was delighted. The three would give birth to at least three children. Along with Son Goshin, Son Gohin, Son Goten, Son Kesi, and Bulla, that would bring his children to eight.
He called everyone together for another celebration. At the banquet, Son Goku said to Vegeta, "Vegeta, you're the Saiyan prince. The task of expanding the Saiyan bloodline should fall to you, not me. Look, I'm about to have eight children already. Why haven't you made a move yet?"
Vegeta said, "Women would only slow down my progress. I'm not going to make trouble for myself."
Raditz said, "Vegeta, I disagree. Kakarot has three women. Have they affected his strength?"
Vegeta flew into a rage. "Shut up, Raditz!"
Nappa quietly said from the side, "Raditz seems to have a point. Kakarot has three women, but he's still the strongest among us. We aren't even close enough to look up at him. That shows women don't have much to do with strength."
Hearing this, Vegeta fell into thought. Nappa and Raditz seem to be right. And Saiyan-Earthling hybrids really do have impressive talent. It looks like I really need to find an Earth woman.
Though the idea had occurred to Vegeta, he didn't want to settle for just any Earth woman.
After all, he was the Saiyan prince. Though the Saiyan race now existed in name only, he had been born into privilege and still took pride in that identity. Otherwise, he wouldn't constantly refer to himself as "this prince."
