A male homeroom teacher at an adult vocational skills training center activates the 'Teaching God System' and takes charge of the most unruly class in the entire center. Facing a group of adult students who refuse to follow the rules, he resorts to unconventional methods: using mahjong games to establish his authority, physical training to punish slackers, and mobile games to guide students toward learning. He tackles every challenge with clever solutions and leads his students into various skills competitions. By the final assessment, their results skyrocket, the students successfully graduate with outstanding achievements, and he completes his mission, embarking on a new chapter of life.
