Which skill levels?

I recommend the fantasy novel " The System Only Has Proficiency ". The main character, Job, had transmigrated to the Barbaric Continent and had a useless but morally unconstrained system. It only had proficiency and no practical help. However, Job still firmly believed that he was the protagonist. Through his tireless efforts, he was able to show off his skills in this world where spells were flying everywhere. I hope you will like this novel. Go and take a look!😋
