Rebuilding the Underworld by Playing the Gods

[To be posted when I'm confident enough to write it. The picture shows the protagonist's design. See the full image at @Jinjiang Author Beidi Yuguang] Song Zhuyi was haunted by ghosts from birth. They drained his lifespan, forever waiting to devour him. But just as he was at his weakest, an app called "Underworld Reconstruction" appeared on his phone. To prolong his life, Song Zhuyi became the new ruler of the underworld. Only then did he learn the truth. The underworld was dead, the gods had fallen, and the once-glorious Chinese underworld, which had existed for millions of years, was now nothing but an empty shell. Worse, the underworlds of other realms all wanted to devour Chinese territory! To rebuild the underworld, he would have to play the part of these newly born gods. And so Song Zhuyi became countless new gods... Before the Bridge of Helplessness, Meng Po, her face half reduced to bone, smiled faintly. "Drink this soup, then cross the Bridge of Helplessness." In the dreams of the dead, a ferryman whose face could not be made out wandered at will and rasped, "I only ferry those bound by fate." In the Hall of the Celestial Emperor, the Judge's ink brush swept across the page as he passed judgment on life and death. "The underworld has its order. It must not be disturbed." Before the Palace of King Yan, the black-robed, crowned King of Hell coldly surveyed the underworld officials from other realms who had broken in to spy. His killing intent was sharp as a blade: "You vermin dare cause trouble in the Chinese underworld?" "Kill them!" Behind the scenes, a pale, sickly young man murmured softly, and the newly born gods took shape with a single thought from him. "Welcome to the new underworld." * Tips: 1.
