Wu Mingsen, a loser in martial arts, is bound to the "Lazy God System" - the lazier he becomes, the stronger he becomes. He does push-ups to catch fish, fights and pretends to be dead, but kills the rat monster with one punch in the toilet and is awarded the title of "Toilet Warrior". He unlocked magical powers by catching fish, made close friends, and also attracted murderous intentions. His classmates colluded with extraterrestrial visitors, and the Warriors Association continued to hunt him down. Three years later, an alien invasion was imminent. Wu Mingsen swept through powerful enemies in the provincial competition, proved his innocence, and counterattacked from last place to a strong pig iron player. Let's see how a lazy boy can defeat foreign enemies and protect the world with his bad posture.
