He is 6 years old, for crying out loud; he should be more lowkey because he can be easily scammed due to his lack of information and dragged into trouble due to his age. It fells like the MC is just being forced to be dumb just for the plot. He is smart, however instead of checking if he is safe to experiment in that place, he just continue to do his shit. Now, there are some people who is looking for him — because they see him casting a strong spell that can obliterate a country.

The Writing Quality is nice, the world building was Ok. I'm just vexed on how the MC act. He is intelligent when it comes to magic and things regarding battles; however the MC lacks some common sense and vigilance. He don't know how to stay lowkey and he should collect more information before he act. He's lack of vigilance to his surroundings causes him inconveniences. Lastly, he should open more common skill gatcha, even if he can't level them up at the same time - at least he has a lot of skill in his arsenal that can be useful to him when some unforeseen accident arrives. He can also acquire some passive skill that can help him hide his mana fluctuation and can automatically sense if there is someone spying on him.
