Siheyuan: My Blueprints Were Classified as Top Secret

After transmigrating as a steelworker's apprentice, Chen Yuan faces a deadly double blow: a neighborhood meeting pressures him to donate his wages, and someone steals the tools needed for his workshop assessment.

He quietly spreads out a blueprint. "I don't have any wages to give, but this technology can double the factory's pass rate. I'll donate that."

From then on, everything spirals out of control.

Hand-ground gears leave military industry experts speechless, while a crudely modified lathe takes on a top-secret project.

Schemes in the courtyard come one after another: stealing his notes, spreading rumors, and even trying to make him "disappear."

But they don't understand: when Chen Yuan's name appears on the national project list, the times are already on his side.

From an apprentice forced to donate his wages to an engineer solving bottleneck problems, he uses a file to carve out an industrial golden age of his own.
