In 2024, Lin Chen, the chief engineer of a certain type of national aerospace engine, died in the line of duty. When he opened his eyes again, he became a technician at a state-owned parts factory on the verge of bankruptcy in the Dragon Kingdom in the parallel world in 1985.
The Dragon Kingdom in this world has been trapped in a technological blockade for thirty years: fighter planes have to be purchased from foreign countries, warships are ridiculed as the "yellow water navy", and the important weapons of great powers have become a laughing stock.
In the face of denial, siege, and assassination, Lin Chen started from a blueprint and used wisdom beyond the times to lead the team to conquer technical restricted areas one after another. When the empire's fleet approached the territorial waters again, what greeted them was the great weapon of the country forged by Lin Chen himself.
