Everyone in the Great Zhou Dynasty knew that Xiao Chengyuan, the king of Zhenbei, was ruthless, ruthless, and had great military exploits. He was a god of war that even the enemy armies were frightened by. But no one knows that the most troublesome thing for this prince recently is not the border war report or the strife between the government and the government, but the fact that Princess Su Wan ran away again.
Su Wan was originally an orphan of a general. On the surface, she was a fun-loving and daring princess, but in fact, she had learned about disguise, traps, and pharmacology since she was a child. She also had a secret involving an old case hidden in her heart. When she married into the palace, she originally wanted to use her status as princess to find out the truth behind the Su family's downfall. However, the rumored unkind prince ended up arresting, protecting, and favoring people in person time and time again, and the whole capital was in panic.
One desperately wants to run away, while the other appears to be letting him go, but is actually closing the net step by step; one wants to make peace, and the other secretly defends him from the knife; from the chaos in the palace, to the undercurrent in the court, to the renewed war at the border, the two are bickering and fighting wits, while joining forces to uncover the truth about an old case from twenty years ago. When Su Wan finally realized that she could not escape from Xiao Chengyuan's grasp, the whole world had been turned upside down by them.
