Dressed as a Prisoner of the Qin Dynasty: I Built Mechas for the First Emperor

Mo Heng, a doctor of materials science, woke up and traveled across the Qin Dynasty, becoming a "demon" waiting to die at the Lishan Mausoleum construction site! In order to survive, he had to use future technology to fool Qin Shihuang: flesh and blood are weak, but steel is soaring! As a result, Mo Heng became the chief technician, but saw with his own eyes: the craftsmen were crushed like ants, and the empire turned into a furnace of flesh and blood. Did he build a boat of eternal life or a demon that would destroy the world? Mo Heng stood on the edge of destruction. On one side are the steel gods and demons who forged with their own hands and only seek destruction; on the other are the cosmic natural disasters that devour all things and come from deep space. How can a body of flesh and blood face this eternal river of steel and deep space? Is it to ignite the spark of humanity and prove the true meaning of "protection" to the cold machine? Or detonate the last technology and cast a faint coordinate for human civilization in the dark forest of the universe? Flesh is bitter and weak, steel soars. One thought can create gods and demons, and one person can face the universe!
