I Am the Guardian of Yin and Yang

The old locust tree in the mountain village bloomed red flowers overnight. Grandpa held my wrist, his nails digging into my flesh: "Guzi, don't raise your head when you see someone in red." I was born with the ability to see the "threads of cause and effect" wrapped around people's bodies, but I just thought they were strange shadows in my eyes - until my grandfather rushed the coffin for Ping Hongsha and violated the taboo of "regardless of life and death". He fell bleeding in front of me and gave me an ancient jade with "Xuanji" engraved on it before he died. That night I realized that I was the reincarnation of the Demon-Slaying Taoist Master from the Ming Dynasty, and what was wrapped around my body was not a shadow, but a bad fate that spanned five hundred years. The river bend where the water ghost pulls the substitute, the dressing table where the contract is hidden, the "Ye Ciao Lang" who knocks on the door late at night... Every time a cause and effect is resolved, the red line on my wrist becomes deeper. Master said this is a burden, but I have to ask: Can I use Xuanmen's methods to control the weirdness of this world? Can I repay this debt from my previous life with my life in this life?
