Expelled from his family on a rainy night, Yan Shu knelt in the heavy rain and watched the door close, but at the moment of death, he awakened the "devouring destiny" power - he could steal other people's luck for his own use. Three years later, he returned under the name "Underworld" of the underground black market, and Lu Qiwu, who had been watching with cold eyes, became the target that he had to kill with his own hands. But when she knelt in front of him holding the blood-stained dagger and said, "I have shouldered the blame for you for twenty years," Yan Shu discovered that there was already a trace of his bones and blood entangled in the life mark he devoured.
