After his death, college student Xingye gained the ability to fully possess others. Yet he unexpectedly possessed a corpse that had been reanimated. This reanimated corpse had once been the holder of a system. Its death and transformation into a reanimated corpse were entirely caused by its own system. This system would assign suicidal missions regardless of the host's level. But Xingye discovered that, as a reanimated corpse, he and this death-defying system actually worked surprisingly well together? Hahaha, I'm already dead. What's there to fear about courting death?(Source: Tencent, translated)
