I Was Weirdly Picking up Trash and Was Called the Cursed King

This is a cursed world. Eighty percent of the world's land has been cursed and turned into wasteland. There are only five major regions left in the world, and human beings are divided into seven levels. My name is Lin Yan, and I am the seventh-class citizen of this world. In poverty, Lin Yan planned to sell himself and go to the cursed land to pick up garbage on behalf of the nobles! Entering the abandoned subway tunnel, he met a kobold carrying a briefcase and holding a ghost coin. Entering the Internet-famous Holy Infant Hospital, the priests and nuns had crosses hanging on their chests, and their smiles had sharp teeth. In the fairy tale-like paradise, there are corpse chasers walking in a hurry; under the Ferris wheel, a man wearing a fox doll costume is kneeling on the ground, shouting for his soul; even the frog doll is abnormal. He is carrying a clothes drying pole with a piece of cloth tied to it, saying that he belongs to the Taiping Legion! … Not only that, but there are also first-class nobles with braids and dragon robes; black-hearted agricultural companies; everyone in this world has eight hundred evil intentions. But what troubled him the most was that he picked up a cursed notebook. When the cursed monsters saw the notebook, they knelt on the ground with a plop and called him the King of Curses!
