In the thirteenth year of the Wei Dynasty, Wei Hansheng, the third prince of the Wei Kingdom, and Nan Xiao, the son of the Minister of Civil Affairs, became brothers under a willow tree and vowed to depend on each other for life and death from now on. However, even they themselves did not know that this love had gone far beyond friendship. As their love for each other grew day by day, the affair between the two quietly spread in the Wei Kingdom. Wei Hansheng even contradicted the Holy Master many times for Nan Xiao. In anger, Emperor Wei suddenly issued an order to exchange Nanxiao as a pledge to the enemy country - Qin. The fate of the two people turned upside down overnight. Watching Nan Xiao's carriage going away, Wei Hansheng made a poisonous oath: He would march to conquer Qin, kill all those who had betrayed him, and protect him for the rest of his life. This begins a bloody love-hate relationship.
