But is swinging your sword for 200 million years in complete isolation actually "living"? That sounds like the kind of private hell that's reserved for only the very worst.Well, normal people waste some of their 0.00000035% to train because for them that's actually 100%.
So he's actually living 28.571.428.571,43% more compared to a normal person :')
Your brain stops its physical "development" in your mid 20's, that doesn't mean that you'll be the same person as back then forever. Gaining 0 mental growth (or avoiding a completely shattered mind) after 200 million years is simply inconceivable.I'm suprised he hasn't gone completely mad. But his body didn't age so maybe his brain didn't either, which could explain him being still so scared and feeling kinda week.
Are you the mangaka?He trained so long but we don't know how strong he is. Stronger than the other girl, but also stronger as teachers? The girl probably trained maybe 10 years, another 10 or 20 and maybe she would be on his level?
