"After you level up, it takes a lot more xp to level up again"
MC reaching Lvl 843 after 3 days
Also MC being an incorrigible asshole whilst refusing to assist a person incapable of civil conduct
MC getting fucked by a chicken is by far the best scene in this whole manga. Our goddess keeps throwing away her pride to please this douchebag, giving him all his powers and the opportunities to gain more, and still he does that shit. Man.
