Siheyuan: I Asked You to Repair a Lathe, Not Build a Missile!

Yi Ran opens his eyes to find he has become a fifteen-year-old orphan in a welfare home in the 1950s?

With a tragic past, he now lives in a courtyard full of scheming neighbors? Luckily, he awakens the [Master Craftsman System]!

Mechanical blueprints and engineering techniques come to him as easily as breathing!

From sewing machines to artillery, from cars to missiles, he rewrites industrial history with his own hands!

After reuniting with his family in the courtyard, he finds himself envied and plotted against by all the neighbors?

Granny Deaf wants to treat him as a backup retirement plan?

Qin Huairu wants to rope him into raising someone else’s child?

Xu Damao spreads rumors behind his back?

The Jia family mother and son throw tantrums and provoke him?

Yi Ran uses one System blueprint after another to face-slap them all, until officials come right to his door to recruit him!

Building artillery, developing missiles, manufacturing new car models...

He rises through the ranks, wins a chest full of medals, and astonishes the world!

The courtyard’s scheming neighbors bitterly regret everything:

How did we ever dare provoke this mighty figure?!
