"I got it. I will drop them all in a multiverse game and then the winner can become my successor."
"But there are too many people, how should I look after them?"
"Oh yes, I can make fragments of a part of myself and let each fragment take care of a single contestants of the game."
"Hmm... That person should be strong, smart and kind. Let's give our contestants a task to gather companions."
"Oh yes, I will lottery to decide to decide which fragment which look after whom."
