Yunchu is the last great ancient demon in the world, who has survived for thirteen thousand years and is immortal. Any force that attacks her will be absorbed and transformed by "The Devourer" - she is a weapon that can never be destroyed and can never stop functioning.
Four hundred years ago, her loneliness reached its limit and she split into the dark personality "Yun Ye". Yun Ye took away the soul-devouring power and started the catastrophe of annihilation. Yunchu was sealed, and used his remaining demon power to reverse time and space, creating the young Shen Du, sending him back to the past, and giving him the only mission - to kill her in her happiest moment.
Shen Du and the Six Kunlun Sons formed the "Kunlun Seven Sons", traveling through time and space again and again, and meeting Yunchu from different periods again and again. Taolin, Snow Mountain, Jiangnan - in every life, he fell in love with her; in every life, he couldn't stop her; in every life, after discovering the truth, she turned desperate and darkened, destroying the world.
In the original time and space, six fellow disciples died for him one after another. In the last reincarnation, Shen Du returned to the beginning of the world with everyone's sacrifices, and found the newly born Yunchu. She had no memory and had not experienced ten thousand years of loneliness. She only saw a young man kneeling in front of her with tears streaming down his face. She stretched out her hand to wipe his tears, but her body began to disappear transparently.
"Don't cry," she said, "you have water all over your face."
He held her, turned into light together, and fell into the ruins where all things end.
There is no more ancient monster in the world. No one remembers the boy with the golden mark between his eyebrows.
