Yuan Kang, a prospective graduate, makes a living by running a "quantum fortune telling" stall. However, while avoiding the urban management, he encounters a strange incident with the mixed-race warlock Romy. When Yuan Kang's mahogany sword crossed the tarot cards, the copper coins became hot and the compass spun wildly. This pair of happy enemies were forced to form a team to take the most difficult test in the academy and enter the S+ level "Nuomian Lost City".
In the maze, the streets and alleys hung with strange masks hide murderous intent. The swarm of disgusting insects and the bronze blood cauldron guard a shocking secret: the remnant soul of the warlock and the shady story of the multinational group "Sanhe"'s experiments on living people are actually closely related to the red rope wrapped around Yuan Kang's wrist in his dream.
When the Taoist priest uses chili noodles to break the illusion, he meets the magician who uses electromagnetic detectors to find the altar, and the Miao girl Sangji uses voodoo to fend off enemies. What they have to face is a conspiracy that spans a century and a "hard-core fusion" of Taoism and magic.
After all, those who can survive between the city management and monsters are the true contemporary monks.
