Review Detail of bereftreader in Life Hunter

Obviously the author's first novel so it has some faults. However, the main character is inexplicably overpowered for almost no reason. It's just a power trip of strong man bashing people for fun. Within the first 5 chapters he's mastered all forms of magic and can create any spell he imagines and just one shots everything. Reads like a fan-made rewrite of summoned slaughterer. If you want actual story, you won't find it here.
