Intern teacher Lu Qian is jointly driven out by the parents of the gold-medal class and takes charge of Class 25, the worst-performing class in the entire school. It has a provincial-level gaming champion, a top-tier archery prodigy, and a student-athlete who dreams of playing professional basketball. Everyone thinks these students are beyond saving. But Lu Qian declares that he has the strongest Teacher System and can lead even the lowest-ranked class to greatness. Through his abilities, he wins over his students and earns back their trust, leading Class 25 from last place all the way into the top ten of the grade. Meanwhile, the parents of the gold-medal class are left filled with regret.
