Siheyuan: Bound to the Wang Duoyu System from the Start

By accident, I transmigrated into the world of the Siheyuan and became He Yuzhu. But something about this Siheyuan world seemed different. The people were the same, and their personalities were mostly unchanged, but the parallel world’s setting was much like the 21st century!

From the start, He Yuzhu was bound to the Wang Duoyu System. If he spent ten billion within a year, he would receive fifty billion in assets for real!

What would happen when Silly Zhu stopped being a pushover and became a secret tycoon?
