I Asked You to Refine an Elixir of Immortality, So Why Did You Turn the Ancestral Dragon into the King of Hell?

After transmigrating into the Qin Dynasty, Su Che awakens the “God-Tier Underworld Forging System.” By harvesting souls and establishing order in the underworld, he can gain supreme divine power. At this time, the First Emperor is gravely ill, Xu Fu's deception is about to be exposed, and the fate of the Qin Dynasty collapsing after just two generations is looming. Facing Ying Zheng's yearning for immortality, Su Che lays his cards on the table: “Your Majesty, mortal life must come to an end. If the human world cannot keep you, why not become the Yin Emperor and establish a supreme court of the underworld?” “Even if my body decays, my will shall still rule the world?” “Exactly! Your Majesty will be the King of Hell, and I will be the Judge. We will ensure that the remnants of the Six States remain subject to Qin law even after death! We will ensure that every god and demon across the myriad heavens has their life and death decided by a single stroke in the Book of Life and Death!” That night, a cold wind howled through Xianyang Palace, and the Gates of Hell swung wide open. Ying Zheng abandoned his mortal body and forged a divine body as the King of the Underworld. The black dragon banners of Qin became soul-summoning flags! Zhao Gao tries to issue an imperial decree? Black and White Impermanence snatch his soul on the spot and fry him in a wok until golden brown! The Xiongnu cavalry rides south? Su Che waves a hand, and a million Terracotta Warriors become undying soldiers of the underworld, devouring their foes alive! Xiang Yu: “I can take his place... Wait, why are the dead Chu soldiers getting up and hacking at me?!” Liu Bang: “I'm not rebelling against Qin anymore! This is terrifying. They even control the dead!” From then on, the Qin Dynasty was no longer merely an empire of the human world. When black dragon banners spread across the Myriad Worlds, Ying Zheng sits high upon his throne in the netherworld, gazing down at the gods and Buddhas of every realm. “I sentence you to die at the third watch. Who dares let you live until the fifth?”
