I, Lu Mingfei, Return from Infinite Space

Lu Mingfei was selected by the infinite space and had no choice but to start a never-ending battle. He has wiped out millions of zombie armies, killed the dragon that dominated the sky, and fought bloody battles against the legions of the evil god Khorne! After killing Thanos alone and becoming a level five veteran, Lu Mingfei finally accumulated enough points and it was time to go back to enjoy his ordinary and boring daily life. However... Wait a minute, doesn't my world only consist of daily life? Slay the dragon? I've probably slain more dragons before than you've ever seen.
