Ling Yunxi, the deposed prince of Dayao, and Su Muyan, the protégé of Beilin, once shared a warm stove on a snowy night in the East Palace and talked to each other about their concerns. They were each other's only light in the darkness. A well-planned palace coup turned Ling Yunxi into a fugitive on the charge of "collaborating with the enemy and treason", while Su Muyan was taken back to Beilin and became the "cold-faced war god" who conquered Dayao.
In the next five years, the two clashed repeatedly in the arena and on the battlefield, changing from close friends to old enemies. When swords were facing each other, they always left a three-point leeway in the dark. The sacrifice of one's life on the edge of the cliff to block an arrow and the late-night confession in the ruined temple revealed that the palace coup was a conspiracy colluded by the two monarchs - they were never enemies, just pawns played by fate.
Misunderstandings are resolved, hatred fades away, and the feelings buried deep in the heart gradually become clear. When the conspiracy was exposed and the world was at peace, Ling Yunxi gave up his resettlement, Su Muyan took off his armor, and the two of them retired to the world together, turning the old dreams of the East Palace and the grievances on the battlefield into ordinary fireworks that they would stay together for the rest of their lives.
