The wish fulfillment is so thick in this story that I can't help but wonder if the author is still okay. This feels almost like his swansong before doing something terrible and irreversible to himself.
Other than that, the attitude the MC exedus is quite gruesome. If he was still the weak, ugly, obese person, it would look natural. But he's not. His looks are now fitting for a professional model, apparently, and he has the myriad cheat skills that make him a total superman. His language cheat alone could make him an internationally famous person, if he so wanted, because he could translate forgotten languages as well. Also, he actually has an "int" attribute as well, which is in the hundreds if not thousands already. Wouldn't that make him a genius? He could probably master mathematics, physics, and such with minimal efforts.
Yet he's all the time acting like he's nothing and the most worthless person on Earth. How would that look like to people who actually still are miserable and bullied (like he used to be), without his incomprehensible cheats? It's like at a gas station a single parent working two jobs and still barely able to afford their mortgage, supporting the children, and paying for some very ordinary, old used car listening to some Gucci and Armani wearing Lamborghini owner millionaire complaining about the fuel prices. Dude should get his head out of his ass and realise he's the luckiest and most fortunate person on Earth (and another planet). Bloody idiot, despite his high int.
