In the tenth year after he ascended the throne, Su Yan was beheaded from the Jinluan Palace by his respected Tai Tu with a sword, and became a prisoner of the Cold Palace. Just when he had accepted to spend the rest of his life with Qin Wan in the cold palace, Li Xi cut off his hope of life with another sword.
When he opened his eyes again, he was reborn in the palace he was familiar with. What he wanted at that moment was not revenge, but finding the "treasure" he had lost.
