What I'd like to know is how one would not go insane after being alone for 200 million years. Only practicing swordsmanship and doing about the same routine daily.
Did you completely miss the part where his perception of time was warped and he hardly remembers his time training so he doesnt even really know what he can do himself
I really don't think being in isolation for that long has no consequence. He should have probably started talking to himself at some point, and lost his mind.
Button that transports you to the extradimensional gym for a 100 million years without you aging: believable
Some magic mumbo jumbo that keeps him from going insane: impossible
You people make no sense lmao
