Siheyuan: Sister-in-Law Qin, Open Up! It's Your Brother

Su Yang transmigrates to a courtyard compound and binds to a ten-thousandfold rebate System. To activate the System, he has to give supplies to beautiful women with looks rated above 90, and get rebates in return! I'll give, give, give! He gives away cooking oil and gets back the universal, top-grade Jade-Fat Immortal Oil, which prolongs life and cures all diseases! He gives away old books and newspapers and gets a bronze tripod and an original Tang Bohu painting! He gives away toy guns and gets advanced drones and electromagnetic cannons in return! He gives away study materials, and the principles of quantum computers and alien technology flood into his mind! In the fight for the position of First Lady, the white lotus tears into the scheming green tea and cries as she begs Su Haoran to marry her! Su Haoran can only say, “I never wanted to be a simp.” But the System is just too generous! Dragon Country: “Whoever dares touch Su Haoran, drag them out and shoot them ten thousand times!”
