Siheyuan: From College Graduation to Joining the Ministry!

Lu Changfeng transmigrates to a Beijing courtyard house in 1959, becoming the eldest son of Lu Jianguo, a Level Five lathe operator.

In his previous life, he was a nationally renowned military-industrial titan. From the start, he presents plans for an aircraft engine, shocking the highest authorities!

To protect this "National Treasure No. 001" from assassination by enemy agents, the higher-ups make a decision overnight: hide him in plain sight!

After graduating from Yenching University as the top student in his department, Lu Changfeng is unexpectedly "reassigned" to work as an archivist in a basement, earning a fixed salary of 27.5 yuan.

The whole courtyard laughs themselves silly!

Jia Zhangshi mocks him relentlessly. "What good is a degree from a famous university? Your pay's still lower than my Dongxu's!"

Faced with the neighbors' outrage, Lu Changfeng scoffs.

Why get worked up over rats in the sewer?

His destination is the stars and the ocean!

While everyone in the courtyard is still fighting like dogs over half a jin of cornmeal, Lu Changfeng has unlimited classified funding to build the nation's most powerful weapons by hand!

Years later, when his identity is declassified and fighter jets roar into the sky...

The whole courtyard watches the news and collapses to the floor in fright!
