Siheyuan: I Lie Flat, but the System Forces Me to Become a Tycoon

Reincarnated as the deaf old lady's own grandson, I planned to lie flat in 1960, relying on my household registration and house. Then I awakened a God-Tier sign-in System that gave me ration coupons for grain, meat, and industrial goods every day. While everyone in the compound was scheming over half a catty of white flour, my warehouse was already piled high. The more I lie flat, the richer I get. The more those beasts scheme, the poorer they become.
