At the Demon Suppression Bureau, I've Secretly Slain Demons for Twenty Years

Evil spirits infest the land, and demons run rampant. Lu Chuan transmigrated into this world and awakened the weakest kind of talent, a Sand Spirit Seed, leaving him with no prospects. Fortunately, he became the world's only ghost constable, able to slay demons and ghosts and earn Yin Virtue! [Spend 100 Yin Virtue to strengthen Sand Power and unlock the supernatural art: Sand Burial Torrent!] [Spend 1,000 Yin Virtue to upgrade the Soul-Slaying Blade to the Thunder Prison God-Slaying Blade!] [Spend 10,000 Yin Virtue to advance from a Third-Rank Ghost Constable to the Yin Son of Heaven of Fengdu!] Lu Chuan joined the Demon Suppression Bureau and secretly hunted demons for twenty years. Rising from ghost constable to Yin Son of Heaven, he took his seat upon a throne of corpses and looked down upon a hundred thousand demons. “If I decree that you die at the third watch, who can keep you alive until the fifth?” I am the Yin Son of Heaven, hailed as a peerless sovereign! I hold Fengdu Mountain, and you shall worship me, the Northern Emperor!
