Please recommend some fantasy novels with two main characters.

I recommend the following two novels to you: 1. The Story of Rebirth: How the Protagonist Fell: This was a fantasy romance novel about a different world. The story was about a cannon fodder villain who wanted to change his fate and learned excellent personal qualities. He wanted to become the main character, but he accidentally discovered that the fall of a main character was a restart of another story. It was very interesting. 2. " My Brother Is the Main Character " was an Oriental fantasy novel. The story was about a person who had been reincarnated into the Divine Wilderness Continent, cultivating and training with his brother and other characters. It had many mysterious colors and was very thought-provoking. I hope you will like these two novels.
