As a modern archaeologist, Yun Jin accidentally died and his soul traveled to the last years of the Northern Yan Dynasty, where he became the deposed emperor who was besieged and killed by the rebels. On the verge of death, he and his rival Ji Ye, who traveled through time at the same time, awakened their past life memories in a pool of blood - it turned out that the two were once monarchs and ministers of the same dynasty, but were torn apart by fate. After rebirth, Yun Jin looked at the world with cold eyes, but Ji Ye stood behind him with a sword in his hand and shocked the six armies with the words "Your Majesty, I am late." When the iron cavalry broke through the city gate, when the old ministers knelt in the dust, Yun Jin raised his head, Ji Ye's sword pointed at his crown - in this life, they were no longer enemies, only to rebuild the mountains and rivers.
