Lin Chen, a young tattoo artist, accidentally inherited his family's lost secret technique of "yin pattern" - a taboo technique that can pierce the power of ghosts and gods and the obsession of dead souls into the human body, thereby changing luck, warding off evil spirits, and channeling spirits. However, every time he uses the Yin Pattern, he will not only bear the negative emotions and karma of the "pattern bearer", but also a corresponding, uncontrollable and weird tattoo will quietly appear on his own back. When the tattoos on his back gradually pieced together a complete "Hell in Disguise", he discovered that he had been trapped in a conspiracy spanning thousands of years and had become a "container" for the awakening of an ancient existence.
