The red moon appears, the eerie returns, and the world becomes a playground of supernatural rules. “Don't open the door when you hear knocking.” “Don't look directly at your reflection.” “Don't speak to the driver on the midnight bus.” Countless supernatural ability users walk on eggshells before these uncanny rules, and the slightest mistake can cost them their lives. Lu Changyuan, the last great celestial master of the Daoist tradition in his previous life, is reborn on the first night of the outbreak, carrying a head full of hard-core folk knowledge and forbidden Daoist arts. Faced with seemingly unsolvable supernatural rules, Lu Changyuan grins. “Rules? You're talking to me about rules when I've got my Eight Trigrams formation and Five Thunder talismans?” A knocking ghost comes calling? He hangs an Eight Trigrams mirror upside down outside the door, then scatters blood-soaked glutinous rice to teach it what it means to “stop at the threshold.” A midnight bus? Lu Changyuan boards with a soul-summoning banner in hand, turning the haunted bus into a private ride for an army of ghost soldiers. While the lofty ability users are still risking their lives to test the rules, Lu Changyuan is already standing on the head of a red-clad vengeful ghost, cursing in the most authentic local dialect: “What kind of supernatural rules are these? They're just cheap tricks our ancestors saw through hundreds of years ago!” A max-level expert reborn in the beginner village, using hard-core folk traditions to solve modern supernatural mysteries and fighting magic with magic!
