I Build the Underworld at the End of the Ming, and Chongzhen Goes on a Killing Spree!

Lu Sheng transmigrates into a book and, empowered by a System, becomes the Book of Life and Death, with dominion over life, death, and the length of one's years. One book, one world; each page, a power! To transcend everything, he chooses the last emperor of the Great Ming, the Chongzhen Emperor Zhu Youjian, as his very first Host. Don't know how to rule? No problem, I'll teach you. Can't judge people? No problem, the Book of Life and Death reveals their lifespan and life story. From then on, corrupt officials are executed, their estates confiscated for the imperial treasury, and after death they are thrown into the boiling oil and condemned to the Avici Hell forever. The whole bureaucracy trembles! The Bureau of the Underworld is established, with branches across the land and agents everywhere. They don't just seize souls; they also serve as the emperor's eyes and ears. City God temples are built to guard each region, letting their protectors travel a thousand miles in the blink of an eye. In life, they belong to the Great Ming; in death, they are ghosts of the Great Ming. Death isn't the end, but the beginning of another cycle. The Little Ice Age brings famine and rivers of blood? Sorry, that's not happening. Rewrite the Book of Life and Death, and life and death are yours to decide. If you say someone lives, they can't die; if you say they die, they won't last until the fifth watch. On the battlefield, Zhang Xianzhong and Li Zicheng watch the Ming soldiers fall, then rise again, and are utterly despairing. Before Shanhai Pass, Huang Taiji looks at the densely packed ghost soldiers floating through the air and is terrified to his very core. Looking back, Zhu Youjian suddenly realizes that, without him even noticing, the Great Ming's territory has expanded across the globe. Zhu Youjian: “I only wanted to be an emperor who restored the dynasty, not ruler of the whole world!? My ancestors had better bow down to me!” As for Lu Sheng, his merits are complete. He ascends to the Immortal Realm, becomes the very embodiment of the Earthly Way, and descends as a myth to rule the world.
