Siheyuan: Don't You Dare Come Over Here!

Shen Yun, a core researcher at a top-secret national laboratory, used the advanced knowledge he carried over from his previous life to make unmatched contributions to the country’s heavy industry and national defense.

He took up a post as deputy director of a steel mill and moved into the Red Star Courtyard.

He’s an iron wall the local ruffians can’t budge, and a steel drill the beauties can’t melt!
