Zhao Siyu, an unemployed social worker, unexpectedly activates an ancient painting passed down from his ancestors, connecting him to He Jinyan, the Zhenbei general who suffered a defeat in the ancient battlefield. Modern times have encountered continuous extreme disasters (heavy rains, earthquakes, typhoons, plagues, etc.), And ancient times have been mired in war (foreign enemy invasions, internal rebellions, and material shortages). The ancient paintings have become a two-way transmission channel, and the two have reached cooperation through "material exchange" to achieve mutual salvation.
