[Traveling through ancient times + modern knowledge + counterattack + imperial examination + power in the government and the public + New Deal] Modern young man Zhao Qian traveled to Zhaojia Village in the Wei Dynasty and possessed a poor scholar. When I woke up, I faced the problem of "marry or join the army". An unexpected boost from modern knowledge. Use it to improve tools, set traps, and answer couplets to get bounties. The ability to use scientific and technological means to solve agricultural, military and other problems is in sharp contrast to the villagers' traditional methods. From a poor scholar to a rich man, and then to becoming an official in the court to implement the New Deal, he finally realized the "Zhao Qianzhong" of the Wei Dynasty.
