The Ninth Prince Tianyong is actually the orphan of the Feng family, a powerful organization family that was wiped out ten years ago. After ten years of dormancy, he stole the national treasure "Linglong Box" in order to take revenge, directing and acting on his own, thus setting up a trap and vowing to lead out the real culprit.
The knight-errant Jiang Leng was ordered by her master to escort a secret key back to its original owner. However, she was involved in a storm and met Shen Yan who was fishing for law enforcement. The two went from distrusting each other to rescue each other, to making an agreement to cooperate, and embarked on a dangerous journey to find the remaining keys and uncover the truth behind the family's destruction.
When the truth gradually emerged, pointing to the supreme imperial power, Shen Yan would not hesitate to take revenge at all costs, even if he wanted to sacrifice his own life. And Jiang Leng, who has always been at his side, has become the only variable in his crazy plan. In the final showdown, he used his body as the key to not only unlock the centuries-old secrets hidden in the exquisite box, but also to open the door to his frozen heart.

Jiang Leng became his only queen and sword. Together, they benefited the world with the mechanism in the exquisite box, and achieved common growth from destruction to rebirth.
