No*************

I think it's okay. Compared with what the author said at the beginning, it's a no-brainer and cool article. Everyone's body is different and they get better at different speeds. Moreover, this is a fictional world of a novel, so there is no need to be realistic. Support the author's dream!

Good to pass the time

Chapter 36 "However, if you get tired one day, you must remember to tell me... No matter where you go, even if it is the end of the world, I am willing to go with you."
