In the Siheyuan, I Propose the Nantianmen Project to the Nation

Zhang Bin wakes up to find that he has been reborn in 1949 as an ordinary boy from Love in the Courtyard! Watching the planes fly past twice during the founding ceremony, his blood surges, and he vows to shake the heavens!

Fortunately, his sign-in System awakens, rewarding him with the [Nine-Turn Immortal Body] on the very first day!

From then on, his life goes into overdrive:

Infiltrating Korea: He becomes a phantom on the battlefield, saving lives with his martial arts, meets the love of his life, and turns the tide of battle with sign-in rewards of cutting-edge technology, forging an immortal legend!

Lying low in the courtyard: While the vultures squabble over trivial matters, he anonymously submits crucial strategies for the nation, quietly propelling China's technology forward!

Commanding the Nantianmen: The Luan Niao aerospace carrier patrols the skies, Xuannü fighter jets enter service, and Chengying mechs make their debut! The steel army he builds with his own hands shocks the universe!

From poverty and deprivation to the stars and the sea, from a grandmaster of traditional martial arts to the father of mechs.

He restores the dignity of young people treated like beasts of burden, lets the elders who devoted their lives to the country enjoy their old age, and raises the Five-Star Red Flag high above an alien base!

When the era of universal evolution arrives, his auxiliary System, [Core Foundation Stone], safeguards the nation's fortunes. Anyone who threatens the country is struck down by the backlash!

In this life, Zhang Bin will not only make up for every regret, but lead the entire nation to the dazzling heights of the galaxy!
