Main plot: Chen Jiu, a time traveler, became the humblest tombkeeper of the Daqian Emperor's Mausoleum. At the beginning, he faced the death of being sacrificed to the evil spirit by the powerful. After awakening the "Item Activation/Enlightenment into Essence" system, he first enlightened the rusty iron sword used for burial and killed the supervisor. In the infinite flow dungeon (the imperial mausoleum is just a novice village, and each level of the mausoleum is a small world), he worked his way up, enlightening the tomb stone beast, the thousand-year-old ancient lamp, and finally enlightened the long-lost jade seal that suppressed luck. At the climax of Chapter 9, facing the current imperial army and the coalition of princes who are trying to steal the country's destiny, behind him stands a million terracotta warriors and horses and a jade seal transformed into a golden dragon. One man suppresses a country and becomes the supreme guardian of the mausoleum.
