Siheyuan: I, He Yuzhu, Am Devoted to Scientific Research

After waking up, he transmigrates to 1950s China, to the Beast-Filled Siheyuan, only to be schemed against by the courtyard's residents from the start, who want him to grow old alone and without an heir?

Don't panic, the God-Tier sign-in System is activated!

Sign in at the steel mill, and earn Grandmaster-level metalworking skills! Sign in at the Academy of Sciences, and earn future technology! Sign in at the nation's border, and earn unrivaled contributions to the country!

While the courtyard's residents are still scheming over petty gains, He Yuzhu is quietly developing lithography machines, building fighter jets, and cracking enemy codes. With his strength alone, he drives the technological progress of the entire nation!

The Eagle: We must eliminate him at any cost! The Bear: We must share his technology immediately!

Facing a global encirclement, He Yuzhu, now a decorated general, puts an arm around his breathtakingly beautiful wife and smiles faintly. "Sorry, but I've already put you on my blacklist."
