Review Detail of Mav12 in My Summons Can Learn Skills

its liked reading teletubies in a novel. what i mean is, the novel wrote just base on around 2 metter radius bubble of the mc. What worse is that the story jump all over the places. The story doesnt has any goal whatsover, there no solid foundation in world building, the character are all there just create platform for the mc to perform,but then again our mc just THERE, he just doesnt has any reason to exist in that story really....its bassicaly slice of life but with power building story just so that he doesnt get killed. The story is really blurry, only the mc is slightly not,then again the mc still vague because the story is just all over the place. Ch 1 he brave the danger and survive, 5 chapter then the mc suddenly becoming a super inteligent and bravest knight there is. What he got after 3 years skip of training doesnt even got any explaination....is he sword user? is he magic user? how good he is with close combat? how good is he with intelectual thinking? the story just progress as if telling you, "Yo mate, this is the mc, he's talented and he is THE MC, after hes training for 3 year any problem that come hes way is solveble and he is THE MC, oh yeah and the scene where he is fighting, the close call scene, the intelectual connan scene, and the scheming unveil scene is just to make it more dramatic, he is THE MC so of course you dont need to know how good he is compare to other, he just there and any problem solve."
