I recommend the following fantasy novels where the main characters cultivate magic: 1. "Global Martial Arts: Transmigration Begins with Demonic Cultivation": The protagonist Liu Zhenfei transmigrated to a demonic cultivator and became a god. 2. The main character, Chen Qingchou, became a devil cultivator and eventually became the world's devil emperor. 3. "The Sword Emperor of the Demon Domain": The protagonist Yun Fangjing cultivates the way of the sword. He has the mountain and river pattern carving. He has reached the peak of the world. He suppresses the demons as his subjects and enslaves the gods of the world. 4. [Calamity God: The main character has magical Dao techniques and special techniques that can kill gods and demons.] I hope you like my recommendation. Muah ~
