Trainee teacher Lu Qian relied on the system to turn Class 7 of Grade 2 into a gold-medal class, but was forced to quit by his parents and was transferred to Class 25, the bottom class in the school. The students in the class are rebellious and mischievous, addicted to games, fighting, and wearing makeup. They are what everyone calls problem students. Lu Qian did not give up, and set the rule that strength came first, crushing the thorny students in e-sports, beauty, basketball, and magic, and winning the respect of the whole class. With the blessing of system cards, he regained students' learning confidence and discovered exclusive talents such as archery and archeology. The hard-core teacher led all the bad students to counterattack, slapped the prejudiced parents in the face, and re-created a true gold medal class.
