Lu Chenzhou, the last descendant of the old aristocracy, killed his colleagues for doing good deeds during the war. From then on, he disguised himself as a lazy and greedy tavern owner, hiding banned books and historical truth deep in the wine cellar. Ten years later, the Northern Empire captured the Southern Principality, and a mercenary group of unknown origin broke into his tavern with relics from the "Era of the Fall of Gods." The female leader of the mercenary group recognized Lu Chenzhou's true identity - she was an orphan who was rescued by him. When the old hatred and the new conspiracy came together, Lu Chenzhou was forced to tear off his disguise and found that he was guarding not only the secrets, but also the last hope of this era.
