His evolution time is independent.
It is unaffected by the time axis inherent in this universe.
But that's not important, he actually has the time and energy to wait for a century.
He won't be bored.
Because for him, almost omnipotent now, it's quite simple to amuse himself.
For instance, slightly altering the positions of cosmic civilizations and enlightening some human scientists with wisdom, thereby pushing the progress of human civilization with invisible hands.
Such a nurturing game, as long as he applies some rule restrictions to avoid cheating, is indeed somewhat interesting.
Besides that, there are many other things he can do.
He can make the world run according to his own wishes.
If unable to expand outward, he can turn inward to seek infinity, creating endless worlds with layer upon layer of nested boxes to make this universe more colorful and captivating.
So, even if he's bored, it won't be within such a short span of a hundred years.
