Zheng Quchi, an expert in civil engineering, unexpectedly transmigrates to ancient times and becomes the ugly second son of a carpenter’s family, disguised as a man.
The moment she wakes up, she’s conscripted: the government is forcing every craftsman in the county to build a military camp?
They can handle houses, sheep pens, horse stalls, and storehouses, but canals, beacon towers, and all kinds of equipment... The country craftsmen are dumbfounded. We don’t know how to do that!
Zheng Quchi: Oh, this is right up my alley.

Zheng Quchi discovers that Da Ye has very few craftsmen who truly understand technology. From basic engineering to military construction, the country relies entirely on imports.
If not for General Yuwen, a fearsome god of war, holding the line, enemy nations would have carved up and occupied the country long ago.
Yuwen Sheng thinks Zheng Quchi is just a humble carpenter. Later, when both their disguises are revealed, he watches proudly as she takes on the top architects, shipbuilders, and carriage-makers of seven kingdoms all by herself... and returns victorious.
My lady, with the enemy army at our gates, I will stand atop the fortress you built and fight for you, risk my life for you, and gladly lay it down. What does it matter?
Behind you, there will surely be me and the great military power I have forged, cheering you on and helping you triumph over all your foes.
