The principal + moral education director of a key middle school on Earth traveled through time and was hired by Ultra's father as the chief principal of the Kingdom of Light.
The Kingdom of Light is full of "problem students": Zero is rebellious, Taro is impulsive, Membius has low self-esteem, Tregear is partial to science, and Beria was tired of studying and got into trouble in his early years.
Lin Zhou did not rely on combat power, but relied on school rules, monthly exams, mid-term and final exams, parent-teacher meetings, make-up lessons, running exercises, moral education points, and punishments to teach a group of cosmic war gods into three good students.
