Shen Ce, 29 years old, is a weapons research and development expert at the country's top military research institute. He is proficient in light weapons, artillery, ammunition, individual equipment, and basic industrial manufacturing. He has a vicious personality, a venomous tongue, and a workaholic. He stays up late and works overtime all the time. His physical fitness is extremely poor, and he extremely cherishes his life. While working overtime to debug a new individual weapon system, he suffered a sudden cardiac death. His soul traveled back to the second year after Qin Shi Huang unified the six kingdoms (220 BC), and possessed a low-level criminal who had just been beaten to death in the suburbs of Xianyang.
No system, only carrying a head full of modern military knowledge, basic theories of materials science, mechanics, and chemistry, as well as a multifunctional military shovel, a tactical flashlight (with only 10% battery left), and half a box of compressed biscuits that he held in his hand before he died.
