According to the information the Grand Minister had provided.
The Dark Demon Realm operated under much the same rules as Zeno's Universe. Dark Angels were generally forbidden from interfering in mortal affairs.
Like Zeno, the Demon Realm Lord held an exalted position and would not act lightly.
That meant his opponents would, at most, go from six Fallen Gods of Destruction to sixteen God of Destruction-level fighters.
Of course, if he slaughtered all their Dark Demon Gods, it was entirely possible that the Dark Angels would break the rules and intervene.
After all, he was the one barging into someone else's home and causing trouble...
But... that was the worst-case scenario.
Son Gohan had prepared three contingencies.
First, naturally, he would see what stance the Dark Demon Realm took. Ideally, they would sit back and watch, letting him clear this on easy mode.
If the Dark Demon Gods intervened, he would have no choice but to deal with them too.
But that would leave him facing a great many extremely troublesome enemies.
That was why his third contingency was Cooler.
He planned to borrow the Potara Earrings from the Supreme Kai. If he had no other choice, he would have to bring out this trump card.
Back to the present.
Son Gohan gave an inscrutable smile. "Of course not. I have another use for you."
Looking at Son Gohan's strange smile, Cooler was utterly baffled.
"All right, go train in the Hyperbolic Time Chamber some more. I'll come get you in five days, and then we'll head to the Dark Demon Realm together," Son Gohan said.
"Mm, all right." Cooler nodded in agreement.
Five days meant five years. He still had room to improve.
Come to think of it, he had already spent twenty years in the Hyperbolic Time
