Even if the goddess and the world oppose him, he will be wizard

I speak Spanish, sorry if my English is bad, I accept corrections.

Niles in his previous life was very smart but he was also a disaster, when he was summoned by the goddess to be reincarnated, he was misbehaved with her and ended up with a malformation that makes it difficult for him to use magic in a world very dependent on it. He will be able to solve the problems and move in a totally different direction to the world but it will not be easy because his father and the kingdom have different plans as they are unaware of his talent for research. Will he be able to balance a life of infiltration and sabotage for the kingdom while he researches and achieves his goals?
