There is a taboo legend circulating in the world of cultivation: Three hundred years ago, a pair of jailer brothers sealed the star pattern Gu and linked their lives to each other through a twin contract, and eventually died together. Three hundred years later, this piece of history that had been deliberately buried reappeared in the world because of a spirit fox with a golden spot on its tail.
Mu Chuxun, a traitor to the Xuantian Sect, heir to the Silver Star Pattern, and a wild swordsman, rescued Linghu in order to investigate the murder of his master, but was forced to form a twin contract with his old enemy Song Qingtang. Song Qingtang, the judge of the Inquisition Department, is of Dark Star prisoner blood, a cold and strict legal practitioner, and he still adheres to the Taoist heart despite being possessed by the Heart-Eating Gu. Two men who were supposed to fight to the death had to embark on a journey to explore the mystery of the Star Palace.
With the appearance of the Bronze Secret Order, they discovered that the senior officials of the Xuantian Sect had long been parasitized by the star pattern Gu, and the true function of the twin contract was to reverse the tragedy of the first generation of prison guards. When the bloody dreams in their memories overlapped with the reality of the plague crisis, from mutual suspicion to back-to-back battles, from spiritual repulsion to star pattern resonance, they gradually uncovered a more cruel truth - this fate that spanned three hundred years was a cage prepared for them from the beginning.
"Since the way of heaven is unfair, I will follow my own rules." Mu Chuxun pointed his sword towards the sky.
"Besides the law, there is the way of heaven, and above the way of heaven... There is you." Song Qingtang's jade hairpin drew a star path.
In this game with the world at stake, can the two people who are doomed to each other cut off the shackles of fate and rewrite the star contract?
