During the Dayin Dynasty, the palace walls were covered with winter snow. Yun Zhi, a concubine of the Yun family, entered the palace as a chess piece, but fell into the love and conspiracy of the emperor Xiao Yan. He is the monarch who bears the vengeance of his mother's unjust death, and she is the spy planted by the family. When they first met, the palace lantern reflected the dragon robe, and his words of "good color" entangled the two of them in a ten-year-old case and thousands of miles of history.
Taiye Pond was attacked, Chun hunted for arrows, and the secret edict was frightening. He worked step by step to eliminate the late emperor's secret chess, and she struggled between the family's mission and her true heart; from the maidservant in Chenyi Palace to the queen in charge of the Phoenix Seal, from blocking arrows on the battlefield in Lingnan to following the life and death of Northern Xinjiang, they uncovered the mystery of Tiao Bao's life experience, burned all the evidence of King Jing'an's crime, and tied the true heart in the blood feud with a knot of unity.
Xiao Yan split his robes and refused to protect her, so she burned blood to hide his birthmark in a book. The plots within the palace walls, the fights on the battlefield, and the counterattacks of the aristocratic family finally turned into a few words in the history books when the snow fell in the plum forest: "My life is a mystery, but I will live in peace." Only the couple who have been tied together for ten years remember their first meeting under the palace wall, the vow of "live and die together" in the flames of war, and how the emperor and she lived each other's only "peace for the rest of their lives" amid intrigues and love and hate.
