Which novels contained elements of urban cultivation and extraterrestrial technology?

I recommend to you the book 'The Lord of the Cultivation City is a Leviathan.' This novel was about a male protagonist, Ling Qianxuan, who was disabled after a car accident. Because of the hatching of the Chaos Kun egg in his body, he obtained the cultivation power of the seven elements of Yin, Yang, and Five Elements. From then on, he began his rise. There are also technological and alien elements in the story. I believe it will suit your taste. I hope you like this fairy's recommendation. Muah ~😗
