Yunzhuo returned in the cold night, eight of his nine lives had been cut off, and each one was engraved with Lu Ye's name. The betrayal in the bloody rain seven years ago caused him to evaporate from the world. Now he returns to the city with a body reshaped by the forbidden power, just to find his last life - the afterimage of his soul sealed in the mirror by Lu Ye himself. In the darkness of the city, superpower hunting, soul weapon trading, and blood moon contracts are all awakening, and Lu Ye is in charge of the black market that devours lives as a "soul keeper". When Yunzhuo's fingertips touched the mirror, the gears of their fate meshed again. This time, it was not killing, but atonement.
