Lin Ye, a young man from a village in the city, is forced to pick up garbage to make a living because of his rent arrears. However, he accidentally picks up half a broken mirror engraved with strange symbols. This mirror not only allowed him to see the ink vortex deep in his left eye, but also involved him in a conspiracy that spanned eighteen years - the Xuanmen pursuit, the mysterious shadow in black robe, the secret of the blood moon...
He soon discovered that he was not an ordinary orphan, but an abandoned infant from Xuanmen known as the "Son of the Blood Moon." His left eye contained the core of the "Soul Mirror" that could subvert the world, and was closely related to a stone door that sealed "Original Sin." The mysterious death of Lao Wangtou, the text message guidance from the mysterious man, the crazy pursuit of the Xinxuan sect, the appearance of other "vessels" one after another... All clues point to the truth: is what the mother sealed with her life eighteen years ago, the hope of redemption, or the beginning of destruction?
When the seven soul-suppressing mirror fragments are gathered together, and when the power of the left eye is completely awakened, Lin Ye must make a choice between the righteous path of Xuanmen, the ambition of the Neo-Xuansect, and the temptation of the "abyss" - to become the key to the abyss, or to be the light that reverses fate?
This is a story about loneliness and redemption, as well as an adventure that travels between the fireworks of the city and the secrets of the Mysterious Gate. Every seemingly ordinary person hides a secret that subverts cognition; every seemingly accidental encounter is a foreshadowing of fate that has already been written.
