I Support My Wife by Collecting Scraps

Song Lan traveled to the ancient times when nothing happened, and a system told him that he was bound to a modern scrap collection station and could exchange scraps of equal value. The recycling price of old clothes is 20 cents per catty, and they can be sold for 100 cents a piece in ancient times, a thousand times profit. Song Lansheng, a top student in finance: I have a head start. Song Lansheng was disgraced and dug mushrooms for a long time, hoping to exchange for fifty pounds of old clothes and sell them to the ancients. His small business could go global. He contacted the owner of the scrap station, who said casually: New type of fraud? Song Lansheng jumped: I was defrauded by the system! System: It's true! The boss is Jiang Ce, you two know each other! Song Lansheng didn't know why Jiang Ce, a popular figure in high school, was reduced to guarding an old scrap station, looking useless and decadent. However, it was Jiang Ce's misfortune to encounter such a struggling person like him. "Your scrap station is full of cardboard boxes. From now on, you will collect old clothes first. These are the best to sell." "Drink bottles, glass jars, sweet potato vines..." "I also want an abandoned bicycle. You can repair it and give it to me." "Brother (*/ω＼*), how are you?" Jiang Ce: "..." What can he do with his first love? When I wake up in the middle of the night, I have to ride a three-wheeled car in the streets and alleys to collect scraps. Later, the trading system continued to upgrade, abandoned love letters (?), Illegal construction, cement roads, old city renovation... In a country that is investing heavily in infrastructure construction, there are so many things to buy! Song Lansheng became a great lord in another world, accumulated some assets, and asked the system: "How many gold mountains can buy that trash?" System: What rubbish! Mr. Jiang has now become the richest man by selling scrap products! Song Lansheng became angry: Should I sell it or not? It's not bad here either. Jiang Ce: Sell. ——Welcome to my city. Daily buying and selling of scraps, everyone is welcome to sell scraps to the protagonist. Purpose: Turn waste into treasure
