In the autumn of the third year of Yonghui, General Shen Jinghong rescued Su Qingyuan, the daughter of the Taifu who was kidnapped by Beidi at Yanmen Pass. Under the moonlight in Guanshan, a promise will last a lifetime.
However, the court is treacherous and the traitor has set up a trap. A secret letter of collaboration with the enemy was copied and executed by everyone in the Su family. On the execution ground, she saw him beheading him with her own eyes and cast a poisonous curse: "May you never lose the one you love and be alone for the rest of your life!"
Three years later, she returned under a different name, practiced medicine and poison, and vowed to kill her enemies with her own hands. However, he became a pawn of the traitor, with his hands covered in blood.
Until the Beidi cavalry committed another crime, the dust-covered pocket watch reappeared, and the blood-stained jade pendant was closed - it turns out that the most painful betrayal is the deepest protection; the most poisonous curse is the truest prophecy.
The snow falls again at the border, and old friends finally meet again. This time, should we join hands with the mountains and rivers, or... Go to hell together?
