Demon High School DXD: Legend of Soul Night

This is my debut novel. Please forgive me if my writing is not good. Thank you! This article is about me, Ling Ye, how to get good things, how to become the harem king, and how to save the earth. I hope you all like it. This article may be based on the works of some well-known writers, so please don't criticize me. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
