After the global "Abyss Tide" incident three years ago, the rules of the world changed drastically, and some humans awakened to the ability to control cards. As an unawakened ordinary person, Chen Mo dropped out of school after his sister (the only relative) became seriously ill and worked at a card recycling station under the "Tianqiong Group". He comes into contact with discarded battle cards eliminated by extraordinary beings every day, until he is accidentally injured and the discarded cards are soaked with blood, awakening the talent of "Abyss Extraction" - he can extract raw energy and even hidden attributes from any discarded cards, but each extraction requires his own life force.
