Siheyuan: A Rogue by Day, Building Military Hardware by Night

Engineer Lin Wei woke up to find that he had transmigrated to the capital in 1953, becoming a young man with no one to rely on in a Siheyuan.

Facing the bullying and schemes of the beasts filling the courtyard, including the Jia family’s greed, Sha Zhu’s thuggishness, and Xu Damao’s treachery, he awakened the Dual Life System.

In the surface world, he is the object of everyone’s scorn in the Siheyuan, a notorious womanizer. His flirtatious back-and-forth with Qin Huairu is just an appetizer. He hoards vast supplies, disciplines the beasts in the whole courtyard, collects their negative emotions, and exchanges them for everything he needs to survive. He lives the good life, to everyone else’s envy.

In the hidden world, when night falls, he becomes a mysterious national treasure known by the codename Artisan. With knowledge beyond his era and the System’s astonishing technology, he quietly gives the struggling nation a series of crucial assists: from improving high-yield crop seeds to optimizing industrial machine-tool blueprints and providing vital strategic intelligence...

This is the story of an ordinary man’s rise, and a glimpse of a great nation’s resurgence. Years later, with a beauty in one arm and the nation’s future in the other, Lin Wei looks back at the beasts filling the courtyard and offers only a smile, his achievements hidden from view.
