Siheyuan: A Pioneer of a Technological Powerhouse

After waking from a nap, Zhou Kai, a top all-around engineer from 2025, found himself back in the sweltering summer of 1960.

That year, after a prolonged drought, the whole country was facing its most severe shortage of supplies.

That year, the “beasts” in Courtyard No. 95 on Nanluoguxiang were scheming to steal the last mouthful of food from an honest man.

A graduate of Harbin Institute of Technology and a 13th-grade technician from the start, Zhou Kai possessed the Great Nation Technology System. Looking at the neighbors with their hidden agendas, he gave a cold laugh.

“Leeching off me? Expecting me to support you in your old age? Guilt-tripping me? Around here, all that matters is precision engineering and absolute logic.”

He hand-built an era-defying “mother machine” from a pile of scrap, then used official factory documents to crush his rivals at a courtyard meeting.

But the path he envisioned stretched far beyond this tiny courtyard.

From high-precision machine tools to specialty metallurgy, from early integrated circuits to the heart of a 10,000-ton ship, from aerospace materials to smart devices that could change the nation’s fate.

With his own hands, he set the gears of the entire industrial chain turning in that barren land without semiconductors.

This is more than the story of survival in a Beijing courtyard. It is one man’s audacious sprint to rebuild his nation’s backbone and claim global industrial supremacy!
