Cien, a saint in the realm of light, was taught from a young age that light is good and darkness is evil. When she was eighteen years old, she was ordered by the goddess to step into the door of death and experience calamity, but she secretly shouldered the secret order to seize the world-suppressing spiritual pearl and kill Yan Xie, the Holy Son of the Dark Realm.
But she didn't know that ten years ago, she saw a young man in black clothes covered in blood in the crack of the living gate. The drop of blood that passed through the ten thousand-year barrier and landed on her cheek had already quietly entangled the lifelines of light and darkness.
After the reunion, Cien discovered that what was written in the holy scripture was not the whole truth. The dark realm is not only evil, nor is the light always pure. She and Yan Xie walked side by side through ruins, deserted swamps, snowy cities, the Kingdom of Spiritual Beasts, and the Guixu Sea. They saw with their own eyes the past events of symbiosis that had been erased from the history books, and gradually saw clearly the ten thousand-year paranoia behind the goddess's mask of compassion.
When the destiny of the past returns, the goddess wants to use light and darkness to determine good and evil. Say goodbye to kindness and thank you, bring all living beings to bear witness, and write down the new judgment of Tianmen.
Good and evil are not determined by one's origin, but good and evil are determined by one's actions.
Light and darkness can exist in each other, and all living beings should be free.
