I recommend " Invincible Immortal Cultivator Monster ", a novel about urban life, to you. The main character, Chu Yunfei, was originally a playboy abandoned by a large family. However, because of a cosmic mystic light, he had completely changed and become a demonic immortal cultivator. He had become the pride of the city and had written a supreme legend. He gradually became invincible on the path of cultivation, but at the same time, he did not want to acknowledge his family. This novel fits the plot you requested, and the main character is also very powerful in cultivation. It definitely won't disappoint you. I hope you like my recommendation.😗
