Siheyuan: Garrison Commander, with Li Yunlong as a Subordinate

[The rating just came out, it'll go up, haha]

[Handcrafted + Siheyuan + Bright Sword + Strong Military Industry + No System]

With a string of military achievements and peerless talent for military engineering...

When Cao Chen arrives at No. 95 Nanluoguxiang in an American jeep, accompanied by an armed guard squad, the animals of the Siheyuan are completely dumbfounded!

In this era of scarce supplies:

Third Uncle is still scheming over two heads of Chinese cabbage? Cao Chen produces a single military requisition document and legally reclaims the unused side room!

Yi Zhonghai uses his status as an eighth-grade worker to bully younger colleagues and slack off in the workshop? Cao Chen charges him with deliberately sabotaging the country's military production, strips him of his rank in front of everyone, denounces him across the whole factory, and sends him to a labor camp!

Jia Zhangshi throws herself on the ground, making a scene and demanding meat? She spreads rumors defaming an active-duty senior military officer, so the military police haul her away and lock her up!

He Daqing abandons his family and children, lets lust cloud his judgment, and runs off with a widow? One special wartime conscription order forcibly sends him into the army, with his monthly pay deducted and sent straight to Sha Zhu and his sister, completely smashing Yi Zhonghai's scheme to rely on him in old age!

In the courtyard, Cao Chen watches with cold indifference. He doesn't bicker or play the saint. He uses an iron military hand to bring the whole pack of animals to heel.

He marries Su Qing, a female ballistics expert who studied overseas and returned to China. They are in perfect harmony, and their life is full of joy.

Beyond the courtyard, he is the undisputed mastermind behind China's defense industry!

The synopsis doesn't do it justice, so please read the novel!
