[System + face-slapping + feel-good power fantasy + comeback] Lu Chen, a normal-school graduate, takes a job at Qingzhou No. 1 High School as the trainee homeroom teacher of Class 8, Grade 11. On his first day, he awakens the [Star Teacher System], which lets him see every student's talent profile and give them buffs.
While other classes memorize a lesson's worth of vocabulary, Class 8 memorizes it all in one go.
While other classes struggle with a problem for an entire lesson, Class 8 gets it in seconds.
While other classes doze off, Class 8 gets more alert the longer they study.
…
In three months, Class 8 rises from the middle of the pack to the top three in the grade, becoming a renowned star class!
But the results come so easily that the parents discover Lu Chen is only a trainee teacher without a permanent position. They join forces and storm the school administration office: “Change our homeroom teacher!”
Unable to withstand the pressure, the principal removes Lu Chen and sends him to Class 12, Grade 11, the worst-performing class in the entire grade.
Facing the parents' cold stares and the smugness of some students, Lu Chen quietly takes back every card buff.
As soon as Lu Chen leaves, Class 8 shows its true colors.
“What was the teacher even saying? I couldn't even save my rank in last night's game…”
“Is this problem meant for humans?”
“How did I even memorize those words?”
Class 8's grades plummet, all the way back to the bottom.
Meanwhile, Lu Chen leads the bottom-ranked Class 12 to a comeback in one month and dominance in half a year. One batch of students after another earns guaranteed university admissions!
The parents from Class 8 once again block the school gates, begging on their knees: “Mr. Lu, please let my child back into your class! They can even stand through the lessons!”
Lu Chen replies coolly, “Sorry, the room is too small. There isn't space for that many people to stand.”
