All 45 classmates travel through time into a chaotic era. Shen Zhiwei and her classmates help their class monitor, Lu Jingyuan, become emperor. But just after the enthronement ceremony, he publicly tears up his vows of loving only one woman for life and sharing the empire with them, appoints another woman as empress, and strips his former classmates of their power. Boldly refusing his decree, Shen Zhiwei sees through his schemes and takes control of the situation. She leads the other 44 classmates in sealing away their core technologies and collectively resigning from their official posts. Fighting off pursuing forces along the way, they flee toward Luoxing Cliff and successfully return to their own time by taking advantage of a total solar eclipse. Back in the modern era, all 45 become outstanding professionals and achieve remarkable success. Meanwhile, Lu Jingyuan loses his empire to treacherous ministers. After his kingdom falls, he spends five years walking back to the modern world, only to become a beggar and freeze to death beneath a bridge.
