A modern top materials scientist, whose lifelong obsession was to develop epoch-making super materials and powerful weapons, died accidentally in an experimental accident. His soul traveled to the Qin Dynasty in parallel time and space, and became the foolish legitimate son of the then Prime Minister Li Si. The original owner fell into the water and was in a coma for a month. After waking up, his temperament changed drastically. On the surface, he was still stupid and dull, but secretly he used modern scientific thinking to research crazily. Under the cover of his loyal maid, he secretly conquered a super new material that was hundreds of times stronger than the current hardware.
From secretly experimenting and encountering repeated suspicions, to overcoming all difficulties to refine the first pair of magic daggers; from being unable to mass-produce and falling into trouble, to the First Emperor calling for the help of the whole country and recruiting capable people and raw materials; the protagonist used modern science to ignite the black technology of the Qin Dynasty, and finally realized the large-scale casting of new materials and new weapons. In one fell swoop, he reversed the crisis of the Qin Dynasty's backward armament and humiliated borders. As a "moron", he became the true god of forging swords in the Qin Dynasty.
