After Rebirth, He Made a Fortune by Collecting Rags.

Lin Yu, who was heavily in debt, was reincarnated back to when he was five years old. What can a five-year-old do? Many friends are still running around naked! God has given me the opportunity to change my destiny. Then I have to pick up the rags and save some money first! Hey, isn't this Yuan Datou? Oh, you are lucky today! Huh? Isn't this the jade that was put in a museum in a previous life? Oh, take it, take it!
