So far up until chapter 70+ while he is starting in the academy the story seems interesting. The concept is quite good yet I have a few concerns.The fact that this was reincarnation after being regarded as a "Grandmaster scholar" of some sort you would think that he should have the knowledge needed to exceed every one. The fact that he became like that before reincarnation should entail that he should have at least the ability to increase his white core among other things. Frankly, his having the knowledge of the past even as a "Grandmaster scholar" shows no particular big advantage to him and to the story. With his knowledge of the past he should have exceeded every kid in the academy but it was basically not the case in the story. I see no point of him being that "grandmaster scholar" in his previous life since the story would be no different if he was a simple scholar. Another one is the pattern of the story. To be honest, it was quite predictable. Its full of a sort of down path (the challenges for the MC) when in a good story it goes like rise before going down. In here, he basically experience continous challenges that seems too annoying since the world doesnt work that way no matter how fictional it may be there will always be a "good or awesome even or encounter" so to speak.
