Siheyuan: I, He Yuzhu, am a trendsetter of the times

This is a courtyard full of love, there is not so much hostility, and the people here each have their own appearance.

Reborn as Why Yuzhu, he carries a system that can be upgraded from a supermarket to a king-level factory.

I want to create my own excitement.

After all, the courtyard is too small, and the people inside are just microcosms of that era.

I will not offend others unless they offend me.

There are calculations and struggles, the characters' IQs are online, and the plot is interesting.
