Hunter Market

100 years ago, the world experienced a disaster when portals appeared from the world's energy expanding. This also leads to the creation of hunters, who go in and delay portal outbreaks. Noah awakens a weird non combat ability, Market, and a devastating penalty that makes him need 10x as much exp than other hunters to level up. Along with many other things that makes him unable to become a hunter. Or does this ability allows him to become the strongest protector? BTW this is my first ever novel and I have many more ideas for novels, but I do not want to ruin them until I get better so please critique this for me to get better. Also expect slow updates
