At the bottom of the cliff of Wuyin Mountain, Princess Zhaoming of the Jiang Kingdom rescued the dying enemy general Jiangsheng out of compassion. The day and night treatment at the Princess Mansion allowed the iron-blooded general to take off his guard and let the golden branches and jade leaves secretly fall in love, but in the end they could not withstand the fateful shackles of "the two enemies". The parting words of "No need to show mercy when we meet on the battlefield" finally became a prophecy - he led the Rong Kingdom's cavalry to cross the border of Jiang Kingdom, while she stood on the tower holding a flute with tears in her eyes. In the light of swords and shadows, can his hidden protection and her unconcealed concern break through the barriers of family and country, and let this love that spans blood and hatred find a glimmer of hope?
