In the 19th year of the Qianyuan year of the Dayu Dynasty, a double plague of drought and locusts that had never happened in three hundred years swept across the Central Plains. The land was bare for three thousand miles, and the fields were full of hungry people. Jiang Shuyue, who was born in a medical family, embarked on an escape journey to protect her tribe, but encountered the disaster of annihilation along the way. Shen Yan, who had been a scout for the Zhenbei Army, was wanted for disobeying military orders and was forced to join the ranks of refugees. Two desperate people met on the verge of death. With the kindness of doctors and military strategies, they led the refugees to survive in the desperate situation. They rebuilt their homes in the ruins, guarded their original intentions in the conspiracy, and wrote a heart-stirring escape epic with wisdom and passion. When the undercurrent surges in the court and the war breaks out again at the border, can this pair of heroes in troubled times turn the tide and restore peace to the world?
