Siheyuan: I Sign In to Do Research and Face-Slap the Whole Courtyard

Lin Xiang transmigrates to 1962 and arrives in the world of Birds Filling the Courtyard.

As soon as he gets home, he discovers that Grandma Jia and a few other beasts have taken over his house!

He expects to struggle through life in an era of scarce resources, but fortunately, he awakens a System and receives the memories of a mid-level engineer from the start, followed by those of a Grade Eight lathe operator. His status and standing improve at once!

And this is only the beginning.

From then on, the electric fans, watches, and radios I make myself are better than the ones for sale!

Synthetic meat, meal replacements, chemical fertilizers, and pesticides all go into mass production!

The Type 77, Type 81, radar... familiar pieces of advanced military equipment appear ahead of schedule!

Lin Xiang battles the beasts, conducts research, and gets to know beautiful women along the way.

Years later, Lin Xiang looks up from his work developing the country and sees that Longguo has become a world power!
