I recommend "I'm Strong, I'm Arrogant". The main character of this fantasy novel had an inexhaustible supply of spiritual power, and his alchemy and medical skills were unparalleled. Moreover, he was very arrogant at the beginning. It was not wrong to act tough, but it was reasonable to act tough! He was strong, so he was arrogant. If you like powerful and arrogant protagonists, you can't miss this novel. I hope you like this fairy's recommendation. Muah ~😗
