Review Detail of DeMolay in SPELLCRAFT: Reincarnation Of A Magic Scholar

The author forgot that the MC is a reincarnated Great Sage of Magic. The MC is a boy with a huge ego and a knowledge of magic, he is not a Great Sage of Magic. The MC's biggest idiocy is going to school!!! He is rich! It was enough to hire teachers for practical classes. Why waste time with children? The whole arc of the academy is very forced.
