Outside the ruins of the Rift Abyss, on the wasteland, Su Yunluo, an orphan of the Sin Clan, survived by picking up totem fragments. Grandma is seriously ill and her bloodline has been destroyed. Any low-level spiritual beast can kill her. The blood tide is coming, and pure-blood nobles begin to capture untouchables as sacrifices. In a desperate situation, she unexpectedly awakens the bloodline of ancient beast whisperers - able to understand the voices of all beasts and even command the ancient beasts sleeping in the ruins. But the "Yi" of heaven has already set a destiny: she must be entangled with Yin Wuxie, a sinister and yandere, for three lives. On the surface, he is an abandoned son of a pure-blood family, but in fact, he is crazy about breaking the destiny. He planted a soul-eating contract on her shoulder when they first met. "Your life is mine, and I can't even take it away from you." He is paranoid about protecting and demanding. When she was finally moved, she found that the only way to quell the blood tide was to sacrifice all her emotional memories of him - forgetting him, Cang Wu would be saved; remembering him, all lives would be ruined. And he chose an even crazier path: to bear the divine punishment for her and use his own origin to feed the blood tide. When her power as an animal whisperer awakens all the beasts for revenge, and when his yandere obsession turns into a cage of eternal night, between the two people on the chessboard of heaven, who sacrifices for whom, and who defies heaven for whom?
