Urban High Martial Arts+Vicious Beast Invasion+Single Female Protagonist+Simulator Lin Yuan traveled back in time to the body of a useless martial arts student and was bullied by the class bully in an alley. He awakened the krypton life simulator on the spot. He didn't have enough talent, so he got the krypton life! Spend one month of your lifespan, simulate mastery of basic boxing skills, and punch the class bully into the wall with one punch on the spot! Being provoked by a student from the martial arts class consumes one year of his lifespan. He is proficient in Xuanji movement and walks the dog directly in the ring! Lifespan is running out? Don't panic, practice this alchemy technique to simulate it, produce and sell it yourself, my fate is up to me! . . . . . . After a while, watching Lin Yuan kill the tenth-level ferocious beast, the students all fell into madness. "What the hell, freshman year isn't even over yet, and you've already become a god of war???"
