It tells the story of the modern young man Zhou Yi who sacrificed his life to save others, but his soul traveled to the ancient state of Chen and was demoted to the county magistrate of Pingliang. In a desperate situation, he awakened the strongest material support system and relied on an unlimited supply of rice, mustard and other materials to relieve victims and rally people's hearts. With modern knowledge and systematic props, he built city walls, opened night schools, trained the army, and developed the county economy. He not only fought against foreign enemies such as the Huns and Khitans, but also wiped out the Heifengzhai bandits who colluded with local forces. From just wanting to live a stable life to caring about the world, Zhou Yi gradually transformed the dilapidated border town into a paradise on earth, and was eventually supported by the soldiers and reached the pinnacle of power.
