Review Detail of Axenzzx in Diamond Kingdoms Space Mage ( Completed )

Worst power progression I’ve ever seen, mc becomes a captain by the age of 15 WITHOUT his grimoire and then after 7 years is still the same strength, the other captains and his own students are as strong as him. Makes a captain kneel by only using mana but can barely defeat any of them in a battle. Some random spy is stronger than him in a lot of instances even though she uses sound magic against his space magic, which is like mud magic against Julius Novachronos time magic, completely impossible to win. Grammar is terrible, readable but mistakes literally every sentence, not to mention the author adds the most random things in sentences out of nowhere. The only good thing about this book is the steady chapters coming out, it’s not surprising to me that his other book only has a 3.8 rating. How this has a 4.8 rating baffles me.
