When Yu Jiuniang opened her eyes from the coffin, the blood moon was hanging over the eaves of the ancestral temple. After a hundred years of imprisonment, she was resurrected as a cold corpse, and the entire clan was her sacrifice. Xie Linyuan stayed by her side, watching helplessly as she tore up the contract and pulled out the nails to kill her bride. Liu Qiniang's paper figurine began to cry, Yun Yinpo's blood talisman spread quietly, and Xie Wujiu's suona sang her unspoken name in the night wind - she was not a scapegoat, she was the destiny to be buried. When the seven nails return, who is the real sacrificer?
After Yu Jiuniang regained consciousness, she killed one person every time she retrieved a soul-sealing nail. The body was resurrected with resentment, and the yin energy flowed through the Yu clan's ancestral hall like a tide. Xie Linyuan secretly guided her to avoid traps in the clan, but Xie Wujiu repeatedly disturbed her mind with the sound of the suona, leading her to fall into the abyss of the blood curse. Liu Qiniang took the opportunity to offer twelve ashes in an attempt to exchange her life for the soul replacement technique, but instead was refined into a new sacrifice by Grandma Yu. Yun Yinpo drew the 'Yin Si Seal' with blood, revealing that Yu Jiuniang was actually the living key to sealing the earth's lineage in ancient times. The so-called sacrifices were nothing but reincarnation containers for the Yin Si of past generations. In order to save her life, Grandma Yu wanted to use Liu Qiniang's soul to refine the Yin Contract, forcing Xie Linyuan to choose between saving Yu Jiuniang or breaking the contract. When the last soul nail was inserted into Yu Jiuniang's heart, she turned the nail tip towards the ancestral temple ground - it turned out that the real sacrifice was the entire clan that had lived for hundreds of years with the blood of innocents. The contract shattered, the underworld collapsed, Xie Wujiu's suona sound stopped abruptly, but Yun Yinpo's blood talisman slowly traced a new name in the wind...
