Intern teacher Lu Qian awakens the strongest Teacher System. With card buffs, he turns Senior Class Seven into a top-performing class in just one month. But the parents think the students earned their grades on their own and join forces to force Lu Qian to resign as homeroom teacher.
Lu Qian records the parents' promises, withdraws all his buffs, and takes over Class Twenty-Five, the worst-performing problem class in the grade. Facing these unruly students, he believes in strength above all. He wins them over through one contest after another, uncovers their talents, and sparks their enthusiasm for learning. Meanwhile, without their buffs, Class Seven's discipline and grades quickly plummet. When the parents from his old class finally come to their senses and seek him out, Lu Qian is leading Class Twenty-Five in a full-on push to become a top-performing class.
