Review Detail of Master_Of_gu in Final Boss of the Multiverse

My friend, the beginning was wonderful, smart and exciting, as I had high expectations for the future of this novel, his special ability was great, the speed was medium at the beginning and good, but the events began at an imaginary speed as soon as he went to the people Marilyn, here the novel began to deteriorate, quickly joined the army (Where Are the dialogues?! Where is the clever deception?! Where are the exciting and dangerous events, I overcame them with an imaginary speed), and quickly killed Zeke, and the giant of the jaw (talk?! Lying?! Deception?! Scenario?! Circumstances?! Nonexistent as well), and quickly! I killed Eren and the rest without a word, without a plan, without any enthusiasm, I don't even know how Annie became frozen in the giant wall and killed her, though in the story in the inner region in the depths of the earth trapped, yet the strange and wondrous twists of the novel did not end, where the hero He began to help the Eldian people to develop and contributed his knowledge and secrets to the development of this people, as he exposed himself that he is not from this world easily, and you say that he is evil and cruel, but why does he care about the welfare and peace of the world, saving the innocent and justice, that he is not of them (this is a contradiction where he killed all The peoples but left the people of Ymir and became kind to them and just?!?), Error 33 his incarnation In the strongest and smartest person in the universe, and having this imaginary intelligence, he can easily make anything he wants. How could he destroy the moon in an instant, with a device he invented in hours?!?! This is crazy, even his cheating power is no longer used?!, Although it is the only thing special in this novel, but I ignored it, sorry for my comment, I hope you benefit from it, so that the enthusiasm and fun that was at the beginning of the novel has gone, and the chapters became a lot of information about physics and machinery industry
