In 2126, Lin Yu, a tycoon in science and technology, accidentally transformed into a useless teacher who was heavily in debt a hundred years ago. Faced with a classroom full of rebellious students, he used future knowledge to launch a dimensionality reduction attack: calculus to accurately trade stocks, physics and mechanics to tear up thugs with his hands, and completely impressed the whole class! He used the podium as his position and led low-level students to build large tactical AI models. Teachers and students teamed up to assist the Ministry of Security in destroying overseas spy networks, crushing foreign technology giants in actual combat, and independently developed the "Breaker" system to slap the entire network of trolls in the face. In the end, Erbenchaosheng counterattacked with enthusiasm and became the pillar of the country! Lin Yu stood on the podium, ready to lead them to conduct nuclear fusion and usher in a new era of technological power.
