I recommend the book, Divine Gathering Technique. The main character's ability was to collect other people's superpowers and magic treasures and increase their power by adding points to them. At the same time, the protagonist also had an ability point adding device, which could add points to other people's abilities. The protagonist searched and collected all kinds of abilities and magic treasures in the city, and constantly improved his strength. There might be three or four female protagonists, so you can learn more about the story as you read. I hope you like this fairy's recommendation. Muah ~😗
