When the campus turned into a hell of rules - the living library swallowed up lives, the twisted ruler turned into a torture instrument, the resentment of the Guangxu years tore apart time and space. Survivor Lin Jiu bears the burden of the sacrifice of his companions and faces the core of the rules. The only way to survive is to "rewrite": use the literary paperweight as an inkstone, use your own physical existence as the ink and pen, burn names and memories, and write new rules that carry the glory of human nature. In the final battlefield where time and space collapsed, he paid the price of self-annihilation and ended the cyclic hell. The survivors ushered in reconstruction under the sun, but Lin Jiu became a blank "night watchman", leaving only a silent paperweight and a shimmering fragment, telling the weight of sacrifice and the price of freedom. Underneath peace is eternal heaviness and watchfulness.
