Intern teacher Lu Qian awakens the "Strongest Teacher System", relying on teaching buffs to lead the ordinary Class 7 into a gold-medal class, but is despised by parents for his intern qualifications not being qualified, forced to resign from the position of Class 7 head teacher, and taking over Grade 2 Class 25, which is last in the grade. Facing this group of seemingly hopeless poor students, Lu Qian takes "strength supreme" as his creed, uses system cards to stimulate talent and teaches students in accordance with their aptitude, from conquering through competition to resolving family dilemmas, igniting the whole class's heart for learning. In the midterm exam, Class 7's grades plummeted, while Class 25 counterattacked all the way, shocking everyone. Lu Qian proves with strength that there are no bad students in the world, only teachers who don't know how to teach.
