In another world, the yin and yang are out of balance, demons are rampant, and powerful practitioners turn into greedy landlords, squeezing the bottom. Luan Yang was originally a grassroots beggar. When he was nearly devoured by evil spirits in a mass grave, he accidentally awakened a "ruined City God's Temple" hidden in the remnants of the eyebrows (containing a special space where time flows extremely slowly and needs to be repaired). By completing the tasks of salvation and suppressing evil spirits, he gradually unlocked the buildings and functions of the underworld (such as Guimen Pass, Naihe Bridge, and Senluo Palace). With the help of many confidants, Luan Yang used his mortal body to fight against the black cultivators and cheating evil cultivators who were suppressed by heaven. As the underworld system continues to improve, he relies on the city god's law and the dark soldiers and ghost generals to defeat his enemies through wits, and finally takes revenge, reestablishes the reincarnation of heaven and earth, and transforms from a beggar who allows others to bully him into the supreme king of hell in charge of life and death in another world.
