Siheyuan: A Dual-Qualified Engineer, Shocking the Entire Factory!

Lin Changqing transmigrates to 1955 as a top technician returning from the Soviet Union, and he's also a cheat with the Industrial Master Machine System.

He only wants to help build the country in peace, but fate lands him in the Beast-Filled Courtyard.

The Jia family is asking for trouble by trying to seize his home? Silly Zhu wants to play the lovesick hero?

Lin Changqing: “Enough pretending. I'm a hot-tempered engineer.”

He has grandmaster-level fighting skills to protect himself, as well as industrial technology that is decades ahead of its time.

His pocket space is packed with supplies, and his braised pork makes the neighbor's kids drool;

His portable factory can produce parts with limitless precision, and his hand-crafted aerospace-grade components leave Soviet experts stunned.

On his first day at the rolling mill, he spots a flaw in the blueprints that has stumped the entire department for half a month. The chief of the technical department is immediately won over!

Yi Zhonghai: “I just wanted someone to look after me in my old age. How did I end up provoking this living King of Hell?”

Director Yang: “Anyone who so much as lays a finger on Engineer Lin is picking a fight with the entire rolling mill!”
