"Listen up folks! I’m living my life with the demon queen!"
Let see what is the selling point. Story is your generic isekai. Nothing new and original here. First few chapters,there's already hint that the MC is the so called chosen one in prophecy. Typical cliche in many story. Maybe he is reincarnation of God or descendant of God,creator. No originality. Then in recent chapters,there are also hint of time travelling. First major arc is tournament arc,also another cliche and it's too long and dragging. So even if the story has no originality,maybe the demon queen is great? Again,nope. She is another generic cliche,a tsundere. Not to mention she is not a pure girl(other males get to grope her,so much for being demon queen,more like demon whore where every males get to grop her),so not a good waifu material. There's really isn't any selling point to this manhua. This manhua did not do anything new that other Japanese manga never done. You are not going to miss anything if you skip this.
It was ok to read when bored. The storyline is typical. But what annoyed me the most is the fact that in chapter 22 mc has no magic and in chapter 33 he said he can't created phone because he dont know the mechanisms of it and yet in chapter 41 he could created mecha, he don't have magic nor prior knowledge of using magic in this world and he couldn't created phone, how did he created that mecha? He just suddenly know how to and that spoiled it for me.
Story - Very slow story and romance progress. Tournament arc is the worst tournament arc I ever seen. There is nothing much I can said here due to the story being too slow. Action scenes are terrible. If you want a action show,just stick to Attack on Titan,Naruto,One Piece,Hunter x Hunter,Fullmetal Alchemist etc. There are people specialize in mage class,combat class,sword class etc but no one ever thought of hybrid among them? Oh well. Art - Definitely the strongest point of this manhua. The artist and the author are two different person and the artist did a much better job than the author. Artist>author Characters - Xiang Ye is alright. He cares a lot for Isabella. Isabella is your one dimensional cardboard typical tsundere girl. Emotionless and no personality outside her tsundere tropes. Villains are edgy as hell. The rest of the side characters are not good and unncescessary screen time wasted on them. Overall - In addition to the slow pace,there are lots of terrible cliffhanger and chapters delay so it's hard to find enjoyment. You know it's bad when you feel more stress than enjoyment reading this manhua. Isabella got defile when other male got to hug her. I prefer my waifu remain pure like many waifu from Japanese romance/harem manga. This manhua has some comedy moments but it's rare. Sometimes,I found it funny,sometimes I cringe at the unfunny jokes. At first,it's interesting to see Xiang Ye use technology from Earth to fight in this fantasy world but later, his knowledge has actually surpass our current knowledge and there's just no limit to his scientific knowledge.
