Siheyuan: I’m a Master Craftsman of a Great Power, and I Keep Everyone in Check!

Transmigrating to a courtyard house in 1980, he becomes a sickly weakling everyone can bully?

No problem, his God-Tier Sign-In System activates!

From the start, he signs in for Marrow-Washing Fluid and Level 8 Fitter skills, transforming from a frail invalid into a master craftsman of the nation in an instant!

The neighborhood bullies mock him? He sells a Lu Ban stool for a fortune, and the whole courtyard falls to its knees! Xu Damao gets jealous and tries to copy him? He only makes a fool of himself in public! Bang Geng tries to steal his craft? A swarm of bees sends him running, covered in welts!

Daily sign-ins bring god-tier jade carving, ancient ink-making techniques, aircraft engines... He has more cutting-edge technology than he can use!

While the neighborhood schemers are still plotting over a single bite of meat, Chen Jianguo is quietly laying plans across the globe, stunning Hong Kong tycoons, directing the tides of international affairs, and preparing to build an aircraft carrier by hand!

Years later, facing the astonishment of the entire world, Chen Jianguo smiles calmly. "I am a master craftsman of the nation. I can crush anyone who dares defy me!"
