It is a good light pokemon fic if you have nothing better to read you can give it a try, note: it has questionable things for certain pokemon connoisseurs and quite a few bad flags for self-insert regulars
Personally, I think he has many cheats, some of them are not consistent with each other;
He can steal data and do tasks, that alone is more than enough to reach the top not only in the world of pokemon but also in other types of worlds (See WoMW Leylin Farlier).
Gacha, come on, that's super lazy.
A minor world, legendary pokemons.
A backpack with most (or all) of the Pokemon * 900 items up to B / W 2.
Not to mention the system with "hidden tasks" is my personal enemy in the vast majority of stories.
Anyone of those is enough to make a fic on your own, having them all not only makes it less serious, if not the point where they feel they are not taking advantage of it.
Original Pokemon are fine as long as they are not abused, only one so far and it is an Eevee that sooner or later will bring out a dragon type in the canon.
Many interactions are missing, it feels like a game record rather than a story, the MC does not interact with anyone, there are only actions and certain ones are quite ridiculous even by the pokemon standards.
He doesn't seem to have a complete plan for the story, just a bunch of ideas stuck together like a collage, an experiment to say the least, or maybe a rough draft for a better story later when his writing gets better.
