In the fourth year of Jianwen in the Ming Dynasty, the "Jingnan" army of King Yan Zhu Di captured Nanjing City. The whereabouts of Emperor Jianwen became a mystery and the country changed hands. Lin Chen, a young man, was originally the son of a small official in Nanjing City. His family was involved in the political whirlpool and his family was ruined. He was burdened with a blood feud and a huge secret related to orthodoxy, and was forced to go into exile. From the ruins of Jinling to the beacon fires of Northern Xinjiang, from the far reaches of the rivers and lakes to the heights of the temples, he changed his name and surname, and dealt with old ministers of Jianwen, Jianghu forces, Jin Yiwei and even Mobei Mongolia. Under the glorious appearance of Yongle's prosperous age, he stirred up the storm in the dark. This is a road of revenge full of thorns and choices, as well as a journey to find one's own morality and the destination of home and country.
