Dreaming of Xianxia

After Wanyu was hit by a car, his soul came to a world with a cultivation civilization for some reason. His soul merged with this world and the remnant soul of a practitioner with the same name to form a new soul. Two different souls, two different personalities, cruelty and kindness in common. What will such a person who shouldn't exist bring to this absurd world? Survival or destruction is only a matter of thought.
