After Entering the World of Immortality by Mistake, I Found That I Had Been Tricked

Zhan Xizhi was a swordsman master in the martial arts world in his previous life, and traveled through time to the world of immortality. He looks bright and graceful on the outside, but is dark and cunning on the inside. He met Xuanli, the great demon from the upper world, in a remote valley in the human world. Forced by the situation, the two had no choice but to form a life-and-death contract. From then on, they share life and death, partner with each other, and bravely venture into the world of immortality.
