Siheyuan: Servicing workshop, modified tank

He Yusheng transmigrated to the world of Love in the Courtyard and became He Yuzhu’s younger brother.

While he was dealing with the "beasts" in the small courtyard.

He became the workshop manager.

[Congratulations to the Host for activating the Divine Research System.]

In the beginning, he used the system to repair a scrapped tank.

In the end, it was changed by the system.

He directly fought against seven people and became the strongest tank in China.

Just as the others were thinking about how to earn more money in this era…

He Yusheng quietly began to help the motherland research tanks, warships, aircraft, missiles, rockets, and aircraft carriers.

One by one, high-tech technologies that had been magically modified were created.

Before the world realized it.

China was like a giant dragon.

He soared into the sky!

He stood at the top of the world!
