Repairman Chen Yuan woke up and found that he had become a prisoner on death row in the Song Dynasty's border army.
Charge: Escape from battle. Punishment: execution by execution.
The executioner was busy sharpening his knife, but he used two spears and several lengths of hemp rope to set up a pulley set on the execution ground, allowing a thin veteran to lift a thousand kilograms of weight with one hand. The whole place was dead silent, and the general supervising the execution narrowed his eyes: "Keep him here."
This is the worst era - there are powerful enemies outside, strife among powerful people inside, the equipment of the border troops is in tatters, and the craftsmen scorn him. This is also the best era - because he is the only one in the world who understands physics, chemistry, and materials science, and there is also a van that traveled with him, filled with modern tools that made the entire Song Dynasty tremble.
Starting from modifying the divine arm crossbow and forging "Chen's Steel", Chen Yuan single-handedly pulled up an assembly line and used standardized production to overwhelm handicraft workshops. When the enemy's cavalry broke through the border town, he lit a Molotov cocktail and used industrial-grade killing to tell the world: in the face of absolute technology, the so-called bravery is just a bunch of cold battle damage figures.
But the edge of technology will eventually penetrate the palace wall of Bianliang. When the emperor's summons and the court's overt and covert arrows arrived at the same time, Chen Yuan knew that the real battlefield was never at the border——
And among the greed of people and the shackles of the times.
Let's take a look at how a modern repairman started as a humble death row prisoner and used gears and steel to create the dawn of industrial civilization on this empire that was about to collapse.
