"Tushancuo: The Sacrifice of the Nine Tails" is a fantasy sadomasochistic epic that spans twelve reincarnations. Nüjiao, a nine-tailed saint, has been entangled with King Yu for three thousand years due to the curse of the "Hetu Sacrificial Array". She lost her memory every time her tail was cut off. He chased his wife nine times and guarded the tomb for three thousand years, giving her a petrified heart in exchange for her rebirth. From the ancient times to the mountains and rivers of the new world, the two were repeatedly torn in "chasing and waiting", "tail cutting and petrification", "forgetting and remembering", and experienced life and death tribulations such as mother and daughter cannibalism, brothers turning against each other, and heaven forcing them into the palace. In the end, they gave up their godhood and transformed into Tu Shanhe and Yu'an, rewriting eternity with "mountains and rivers living together". The story begins with "Qingqiu Fox owes no favors" and ends with "Tushanhe only owes each other", exploring whether the nature of love is obsession or fulfillment, possession or symbiosis.
