The South China Sea is roaring, and the blood flag is hunting. In order to protect the royal tribute Yunjin, the loyal Su family fought bloody battles on the Merman Island to seize the treasure. However, they were ambushed by "pirates" and their children were killed and injured. This was the beginning of the vicious plan of Xiao Chi, the powerful king of Ning. Framing, plundering, and killing, Xiao Chi pressed hard step by step to seize the Su family's Yunjin secret skills and Jiangnan wealth. Eventually, the blood of his loyal minister Su Wenyuan was splashed in the palace, and his daughter Su Mingxue was brutally humiliated. The century-old Su family collapsed.
The mantis stalks the cicada, followed by the oriole. The new emperor tolerated his plan and finally knocked the domineering prince off the altar. Prince Ning, who had gone through great changes in the past, was shackled and became a prisoner exiled to the border. The cruel gears of fate were turning on the desolate border - Xiao Chi unexpectedly met Su Mingxue, who also lived here and bore a blood feud.
Is it revenge of an enemy, or a mockery of fate? Beacon smoke suddenly rises in the north, iron hoofs knock on the gates, and the country is hanging by a thread. The exiled sinful king and the orphan girl tempered by blood and tears were forced to face each other in a desperate situation. The sand and war on the border, as well as the reflection of Su Mingxue's unyielding soul, violently shook Xiao Chi's heart, which was blinded by the desire for power. From a selfish and ruthless schemer to a barrier protecting his family and country, a thorny and bloody road of redemption stretches at his feet.
Can the sins of the past be repaid? Can the broken loyal soul rest in peace? A piece of blood-stained brocade implicated the grudges of two generations, and finally weaved a majestic tragic song about betrayal, redemption, and the righteousness of the family and country amid the border smoke, witnessing the legendary transformation of a sinner king who will be remembered throughout the ages.
