Yang Mobai was once an inconspicuous nighttime debt collector in the old district of Linjiang, handling shady accounts for small companies. One night, while chasing down a debt, he stumbled upon a bizarre murder in an abandoned urban village. The victim had died in a gruesome manner, yet the scene looked as if someone had arranged it in advance. That same night, he awakened the “Fate Card System,” which let him draw temporary yet powerful abilities, identities, and fragments of memory from a card pool. As one card after another lit up, Yang Mobai discovered that the turf wars, disappearances, and blood debts from illegal loans plaguing Linjiang all concealed the work of an inhuman being who constantly “changed identities” to control the lives of others. Like a hunter moving through different lives, this being specialized in stealing other people’s fates. To survive and uncover the truth behind his father’s violent death, Yang Mobai had no choice but to endure humiliation in the muddy back alleys, pretend to sink into depravity, and inch his way into the heart of the darkness. But when he finally drew close to the truth, he realized that he might have been chosen as that being’s next vessel from the very beginning.
