He has unlimited time and unprecedented life experience:

[You solve 5000 math problems and get the achievement: [Prince of Mathematics]]

[You do 20,000 push-ups and develop a physique: [Perfect chest muscles]]

During that period of growth that no one knew about, he created infinite possibilities! ~
