Siheyuan: I specialize in machinery to benefit China!

Li Qing travels through the world of “Love in a Courtyard” and awakens the sign-in and check-in system.

The yard is full of farts and beasts everywhere!

He even tampered with his father Li Dong’s funeral ceremony, and directly gave all the money to the old Li’s family!

Even forcing my mother to sell the house at a low price?

Of course I can’t bear it! Li Qing violently punished all the beasts, and sent Yan Bugui and Jia Zhang inside without mercy.

As a college student majoring in mechanical engineering, he has been blessed by the system, and he has been racing all the way.

Countless products that do not belong to this era have been manufactured one by one.

Benefit China!

Qiao Jingjing: My husband is the most family-friendly!

Director Yang: Engineer Li is the most patriotic person!

Qin Huairu: My dear Qingzi, my sister made a mistake, please forgive me this time…
