Goku and Vegeta had taken a new threat, though it was from another timeline.
Gohan was shocked. While he was idle, this Kaioshin named Zamasu, seemingly took the Super Dragon Balls, more powerful than the Dragon Balls and performed a series of tasks that allowed him to be a threat even to Goku. He abused the laws of the universe like a munchkin. His whole timeline ended up erased. Also there was a god even above Whis.
Zamasu, it seemed to Gohan, was a scholar acting on ideals. He talked to the Kaioshin and to Whis. His mentor had no idea he'd turn this way.
"People who fight for the Greater Good in such a manner... don't turn out to be good," lamented Whis.
But while Zamasu took a stance that he claimed was logical to him, it was something about nihilism and hating ningens. It merely gave a bad name to the writers of his rational books and people who took an ideal. He hated ningens, and somehow claimed it to be rational. This wouldn't do for humanist Gohan. Wasn't it possible to do better and use his book to improve the world? And why only this world? There were many timelines, it seemed.
He then became... Super Rational Gohan 2.
Gohan asked for a radar and gathered the dragon balls. It was a low fruit, sure, but he could do that.
"I wish for unlimited bliss to consciousnesses..."
This dragon, he found out, had only the power to create small pocket universes that did this. He still needed to consult a bigger dragon. He had to do what Zamasu did and find the Super Dragon Balls.
"Why don't we, like, do the God Sayan dance for all the Sayans?"
"Let's do it!" replied Goku.
"Hmph, I prefer much to acquire it on my own," said Vegeta. "But I agree to."
"Why no God form for humans?" exclaimed Kuririn.
They did this dance and he re-emerged as... Super Rational Gohan God.
He wondered if he could transmit his knowledge of martial arts through writing a book on the subject. That way, even if they weren't at Sayan levels, humans could get stronger in number.
He asked Goku how to do instant transmission to speed things up.
If Zamasu could, why couldn't he? He took Bulma's super dragon ball radar and found them.
He formed his plan.
He'd create a race of perfectly maximized happiness people and make multiple universes and timelines with them. He then had another thought. What if a different race was to threaten them? So he'd make them good martial artists too. And what if they could absorb other races and they'd be happy too? That would be similar to Buu's power. The Happymajin, so-to-speak.
All of that was possible with the Super Dragon Balls.
Of course, as soon as he'd arrange them, he could go back to the immediate past and make a wish again.
In fact, he took Bulma's time machine too.
He also trained in the time chamber for a while just in case.
"Too many universes." Zeno thought and zapped them. He thought the new universes were too boring, as they were so perfect nothing was done in them.
The Grand Priest observed that someone was interfering with the multiverse's old laws set by the gods. You weren't allowed to just make happy beings. There had to be tyrant gods who destroyed things to balance it out like Gohan's friend Beerus.
A foil to Gohan's plan.
