She is the human empress, holding a sword to control the mountains and rivers; he is the orphan of the demon emperor, half-dragon blood, and was nailed to the dragon cliff.
She died for him in the previous life, and he broke his heart for her in this life. The two emperors are bound by a blood contract. They share the same life and death, and are not tolerated by the three realms.
No system, no golden fingers, just two hearts that stand side by side.
She protects him in his rehabilitation, and he protects her from danger; they pet each other and flirt with each other, which is so sweet that it makes them lose their teeth, but also makes them suffocate.
When the world forced them to die, they overturned the world——
"The name of the sword is Changzhao, Changque's Chang, Xuanzhao's Zhao. When the sword is with the person, but the sword breaks - he blocks it for her."
