Siheyuan: I Hand-Build a Computer and Shock the Nation

Li Xiao transmigrates to 1950 and becomes an engineering prodigy ranked among the top three in his year at Peking University. He also finds himself with two younger sisters who have lost their father and have no one else to rely on.

The original owner was just beaten to death in a robbery by Zhang Ermazi, and now the man has come back to demand money.

Li Xiao takes a fountain pen and drives it through his palm, then cripples the thug with a kick. Yi Zhonghai and everyone in the courtyard immediately step back.

But his real goal isn't to fight with the courtyard's assorted scoundrels over housing.

The computer in his pocket dimension contains industrial knowledge from the future. Starting with machinery repairs and engine modifications, he sends plans for gas-cylinder cannons, rocket launchers, and vehicles to the testing grounds, one by one.

At last, his sisters have enough to eat and warm clothes to wear. Wang Fang watches him go from a university student to a protected military-industrial prodigy.

While the people in the courtyard are still getting jealous over a few pounds of meat, the country is already waiting for Li Xiao to unveil his next major invention.
