That Cloth Sticker, Don't Run Away

Xian Yi met an old woman dressed strangely at work one day because she had no money to buy breakfast. She kindly bought two buns and a cup of soy milk for her. In return, her mother-in-law gave Xian Yi a pair of jeans with several cartoon patches on them, saying that the pants would protect him if he was in danger. When he encountered a danger, a cloth patch disappeared. When he encountered a car accident, all the cloth patches on his pants were gone, but he was still wearing pants at that time. So in order to survive, with the help of the system, he had to go to various worlds to find cloth patches that transformed into various people.
