My Parents Skinned Me to Save My Younger Brother's Life. I Returned from the Coffin.

The black sun hangs in the sky, and the darkness is as gray as snow. Since the "dark disaster" came, the living people were worse than dogs, and the streets were full of dead people. In order to prolong the life of their frail and sick younger brother, their parents personally peeled off the human skin of their older brother Feng Tianqi and made it into a "human skin lantern" that could ward off evil spirits. Feng Tianqi, who was abandoned in a mass grave, woke up in a coffin covered with paper. He found that his body had become a paper-pricked person with bamboo strips as bones and white paper as flesh. When the strange suona sound sounded in his mind, he picked up the paintbrush and added a pair of scarlet eyes to his paper body. "Since you are no longer a human being, then you will become... A living Yama in this world."
