In his previous life, he was a national-level chief designer of small arms and a senior engineer. He presided over the development of several main field-installed models. Now, he is a mine slave who is contaminated by radiation and on the verge of death.
Buried alive in the mines, companions waiting for death in despair, slave owners sharpening their knives - the beginning is hell difficulty.
While others are working hard, he is drawing blueprints. While others grabbed a piece of bread, he rebuilt the water purification system, climate-controlled greenhouses, cement factories and power stations. Others fight with brute force, but he fights with the industrial civilization accumulated by mankind over thousands of years.
Starting from an iron spear in the mine, starting from the first furnace of alloy steel, starting from the first crop of green vegetables planted - a new era belonging to the creator is slowly rising on this ruins.
