Travel through time and become a warlock about to be killed in the Qin Dynasty? Shen Bo was tied to the execution ground at the beginning, and Ying Zheng sneered and wanted to bury him alive. At the critical moment of life and death, Shen Bo shouted: "I can make cement! Build the Great Wall and build the Chi Road, so that the Qin Dynasty will not fall for thousands of years!" Ying Zheng was dubious, but Shen Bo poured out the concrete and hardened it into a steel-hard city wall within a day. The tyrant was overjoyed and directly made him a national advisor. From then on, the Great Wall of Concrete rose from the ground, concrete warships roamed the seas, and the remnants of the Six Kingdoms begged for death. So cool!
