Review Detail of Khaled_Azzam in Holy Necromancer: Rebirth of the Strongest Mage

currently on chapter 400 and I think this is a great novel. However, a problem i had with it was that most of the time alot of the characters know something about the secrets of the MC that the MC himself doesn't know about, at first it was okay bit it kept happening again and again that it got annoying. One more problem is that the MC seems super OP yet not OP at the same time and I'm all for it but the way its presented is annoying. He's super talented that he can absorb many crystals easily to improve and he stole alot of crystals from the academy. Moreover he has two grimoires(2 of the strongest elements),3 ancestral staffs and has high proficiency in 3 elements and he no longer has problems with his physical body due to the necklace. why the he'll does he struggle to kill the Holy Lord of wind when he was in the academy he should be able to wipe the floor with him. Moreover after Gabriel defeats izen its supposed to be something great introducing that he was a little brother of a guy on a mountain and that the world they currently live in is a desolate world takes away from the victory and makes you feel that instead of winning he failed by attracting attention of more enemies.and why does everyone know that Gabriel is karyk while he doesn't its super annoying that you just want to scream at Gabriel to figure out the obvious. To summarise 1) The others know more about the MC than the MC himself 2)The MC is not wiping the floor with others simply because of Plot instead of a good reason 3)Whenever the MC wins you figure out that the opponent beaten has a stronger opponents behind him
