Overnight, the family of Shen Moyuan, the young master of the Jiangnan family, was destroyed, and he embarked on the road of revenge with only half a piece of "Panlong Jade". He originally thought that his enemy was a notorious demon sect, but he didn't know that he was actually the prince of the current dynasty, and the man behind the scenes was actually his uncle King Zhao who seemed to be loyal and patriotic and had ascended to the throne!
The shocking conspiracies of the rivers and lakes and the court are like a net. Shen Moyuan was forced to be involved in this power storm, and formed an unforgettable relationship with Lin Qingci, a cold and aloof "fairy swordsman", and Qin Suye, the enchanting and infatuated saint of the devil's sect. At the critical moment of life and death, he clashed swords with his brother, who was a killer of the Demon Cult, and struggled to recognize each other in blood and fire.

Between the flame of revenge and the benevolence of helping the world, between the great responsibility of the country and the true love of the beauty, what choice will he make? A chivalrous legend about family, country, brothers and love begins...
