I Had the Legend of the Sword Immortal Li Bai in Young Songs

The protagonist is a 21st century otaku. He has been nothing out of the ordinary since he was a child. He has a father, a mother, a brother and a sister, that's right. He also has a small wish, that is, to spread his wings a little in a world where he is hard to reconcile, and change the ending of his uneasy life. Of course, this ending may not necessarily be good, hahaha, I'm a newbie, please bear with me. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
