Gu Changfeng, a pillar of the country and a top aviation engine expert, had an accident during the testing of a new hypersonic engine, and his soul traveled back to the "Donghua Republic" more than 40 years ago.
He became a disgraced young technician in the dead of winter.
Here, it is the late 1960s when passion and poverty coexist. With a weak industrial base and a mountain of technological blockades, every step of cutting-edge military industry is extremely difficult. The blades of turbojet engines break frequently due to inadequate materials, and the heart of a fighter jet may stop at any time; the steel plates of battleships are not strong enough to withstand the water pressure of the deep sea...
Facing the faces full of desire and perseverance, facing this country that is full of waste but full of infinite hope, Gu Changfeng's blood boils again.
In his mind, there is a technological blueprint that will lead the world in the next few decades; in his hands, there are tools and drawings that are so crude that they are useless.
Then start with a small turbine blade and use technology and knowledge beyond the times to ignite this fiery furnace called "military industry"!
The dusty workshop is the starting point of his counterattack; the mottled drawings are his picture of rewriting history. Side by side with the tough and intelligent female technician Shen Qinghe, he overcame the challenges of materials science, precision machining, aerodynamics, etc., And turned the impossible into reality.
From falling behind to catching up, from catching up to surpassing.
When the "swords in the sky" roared and pierced the sky, and when the "behemoths of the deep sea" plowed through the vast expanse of blue waves, an era of great power and heavy weapons belonging to Donghua was opened by him.
This is a story about a man who used his knowledge and blood to forge a sword for his country in an era when technology was booming, and eventually became a legend for a generation.
