Three Hundred Years Ago·Predestined(Background Dark Line)
At that time, she was not the Saint of the Netherworld Sea, but an orphan girl who was regarded as a "disaster" in the mortal world. He went down the mountain for training and saw that she was about to be burned to death by the villagers, so he came to save her. She was burdened with the body of annihilation, and he searched all over the world for her to no avail. Finally, he broke into Tianji Pavilion alone, and at the cost of his own three hundred years of life, he tampered with the book of cause and effect and changed her "destiny of death" to "destiny of cultivating immortality."
Those who tamper with cause and effect will be hated by heaven. The cinnabar mole between his eyebrows is the mark of heaven, and every full moon he suffers the pain of being bitten by thousands of ants.
He sent her into the Netherworld Sea - because only demonic techniques can suppress the body of destruction. When she woke up, she saw another disciple of Xuantian Sect (his junior brother) standing beside her, and mistakenly thought that he was her savior.
He never explains. The explanation is to expose the tampering of cause and effect, and Heaven will immediately take away her life.
