This book is about a university student who transmigrated to the cultivation world for 500 years and finally became a supreme-grade pill king in the Human Realm Upon Heavens. However, when he was refining the divine blood pill, he was ambushed by a group of immortals and his pill was stolen. He took the heaven-defying divine blood pill and self-destructed. When he opened his eyes again, he actually returned to his original city life. I hope you like this fairy's recommendation. Muah ~😗
