Lu Beichen, the Dragon King of the North, the patron saint of China, was betrayed by his love and brothers in the peak battle. He was poisoned by a strange poison, his dragon bones were taken away, and he fell into the vast East China Sea.
When he was rescued by the kind-hearted daughter of the Su family and hid in the city pretending to have amnesia, he accidentally became her "shield" for rejecting the family marriage.
The former king has become a son-in-law, and all forces are secretly watching, and murderous intentions are everywhere.
But he doesn't know that the alluring fiancée who betrayed him has climbed to the top with her keel and is laying a dragnet, vowing to squeeze out the last of his worth...
When he takes off his disguise and returns to the north, the whole world will tremble!
