Guitou Lie is the humblest "blank slate" in Guzhong Village - he has no life card and no rank. Even if he is killed, he has to pick up the rags and replace them with coffins. He plucked broken cards from the pile of corpses and gnawed on rotten rice to survive until he found a stone plate under a withered skeleton. It was a portable training room—a space that could infinitely dismantle and reorganize card rules. From then on, he began to farm like crazy: in the first volume, he built a defensive village, in the third volume, he cracked the batch card-making technology, and in the sixth volume, he raised a loophole army full of blank slates. When the Mido family's samurai crushed him with high-level cards, he smiled and paid ten years of life to activate a useless card that was despised by everyone: "Perish together" - a loophole in the rules allowed him to fight back against the nobles. But every promotion comes with a price: organs, lifespan, and the lives of companions. At the end of the second volume, Nekomata Nadeshiko blocks a fatal blow for him; in the fifth volume, the bone ghoul demon Zang's soul is scattered. Tragedy is the background, and humor is the antidote. Guitou Lie stood on the enemy's bone mound and bowed deeply: "Thank you for not killing me back then. Now it's my turn to slaughter the country."
