Review Detail of Lintiun8 in Skill Creation in the Fantasy World

So, I'm here giving 4 stars. I started reading this novel because of the free chapters and to be honest I was intrigued by the idea of ​​the MC creating his own abilities. Well, what can I say, this part that should be the most important is poorly used, very poorly. The mc creates many skills which are quite weak and useless in the future, can he upgrade then? Yes, he can, but he will have to pay more to be able to do it. Things like he doesn't have an affinity for mana, a smart MC would create a skill that would help him have an affinity, he doesn't. Or an inventory, he could create a simple one but he doesn't, he could create a resistance one since he made an agility skill that he basically uses once and his resistance is almost completely depleted, but he doesn't create it and he gets exhausted in fights. And yes, although some skills are expensive, the author already stated by the system that the mc could limit the skills with cooldown or something to make them cheaper, but no, the mc prefers to create stupid skills instead of good ones with some limits that will be better. Now about MC himself, he is from the earth, he died and was transmigrated into a slave boy, now don't think that because he is an adult in a boy's body he will act like an adult, because we won't. If I didn't know he was transmigrated I would have thought he was just another kid, because he acts like one, it doesn't seem like he's an adult, he screams out of nowhere, he has anger issues, he doesn't know how to think straight, he believes very easily in strange people, doesn't know how to create good skills (even when he read a lot of novels in his past life and watched a lot of anime), he basically acts like a child, so if you think that somewhere in the chapters up to 109 (the one I stopped) he will act like an adult, sorry, but he won't. The world building is very good, you het hooked up very easily on it because the author knows how to make a good pace. The updates are good, there is good story development that makes you wondering what is going to happen next. The thing that i like the most was the secondary characters, the author nailed that part. They are not bland, or just there to fill an empty space, no, each one has their own personalities, likes and dislikes, etc, its very good (i think the author forgot about the unofficial members hahaha) Overall I liked it, I was really captured in this novel, and i recommend giving a chance
