Intern teacher Lu Qian leads Grade 2 Class 7 to counterattack into a gold medal class, but faces a collective coercion from some parents demanding to replace him. Lu Qian superficially agrees to be transferred, quietly records the parents' rhetoric, and unbinds the system card blessing of Class 7. The parents successfully hand over the gold medal class to the new head teacher Zhang Chao, while Lu Qian takes over the school's bottom-ranked Class 25. Class 25 is full of naughty and rebellious students. Lu Qian activates the system, opens the strength-supremacy competition rules, and successively competes with students in games, makeup, arm wrestling, and magic poker, winning one after another. He uses strength to conquer a crowd of rebellious students, and also triggers new system tasks, preparing to lead the bottom-ranked class to start the road of counterattack.
