@Locator i read the novel some years ago so it's hard to remember all points but to be honest, they ruined the ending with fast pace. He fought the last demon king so hardly and after killing him, he found out that there are 72 or around demon kings actually, and the number of demon kings he knew or killed were the weakest, it was revealed that he was reincarnated because of a demon king. one more thing is mc friend who is known as piggy, has some insane powers
