Shen Cheng traveled through time and became the principal of a private vocational school, activating the "100-fold rebate for students' money spent" system. He stood up to the school board of directors, spent his own money to install air conditioners, build a library, and set up an ice cream station. He used real money to improve the campus and won the die-hard followers of three thousand "bad students." From Pheasant Vocational School to the top in the world, he spent money to educate people, counterattacked and slapped people in the face, becoming an educational legend.
