There is an evil creature in the Huai family, named Huai Yin. It is naturally vicious and unintentional. If it is contaminated by the yin energy around her, it will reduce the luck and cause death or injury. But for people in the metaphysical world, this is an excellent magical weapon.
There is a pair of twins in the Cheng family. The elder brother has a body of pure yang, and the younger brother has a body of ultimate yang. If there is any difference between the two, it should be that the former can be immune to all evil and frighten thousands of ghosts, while the latter can burn himself alive.
Brother Cheng Sheng: "You have to remember your identity. You are a magic weapon. Don't get too close to ordinary people."
Younger brother Cheng Yu: "A Yin, no matter how you like it, you must have something you like. You must have something you like."
Intention: Blooming in low places, meeting mountains and seas.
