Lin Yu, a tech titan from 2126, wakes up a century in the past as a debt-ridden, mediocre college instructor. Facing a classroom of rebellious underachievers, he uses future knowledge to blow their minds—predicting stocks with calculus and taking down thugs with physics. Together, they build a revolutionary tactical AI, bust a foreign spy ring, and crush global tech giants. Now, with his students transformed into elite minds, Lin prepares for his wildest project yet: nuclear fusion.
