City: the Strongest Immortal Cultivation System

Night Breeze traveled to a parallel world. The difference in this world is that there are warriors. Powerful warriors can even fly across the sky and ignore most thermal weapons. Although this world is a technological world, there are only yellow people, and only four empires rule the world. And Ye Feng has awakened the most powerful system of cultivating immortals. While others are practicing martial arts, I am cultivating immortals, creating wind and lightning along the way. This novel and its characters are purely fictitious.
