This manhwa is actually fun to read. At first few chapters, the art was lacking and the cgi they used are standing out like a sore thumb. The characters felt out of place with background but later the art improved a lot. Early art: 6/10 Latest art: 8/10 The storyline isnt so different than most regressor manhwa where mc go back time to save the world. But i like the progression as it isn't rushed and built up well. Storyline: 7/10 The characters, to me, i like the mc because he is not your average know-it-all guy and plot-armour was rarely used. He is a human that has his owncomplexity as he didnt have a good past life. From there, you can see his development from cold rude bastard to decent human.
For the side characters, they are well-written. They dont feel like props that added to make mc shine the most. They have their own story and personality.

Characters: 7.5/10

Most people dont like this manhwa because the mc arent acting like they want. They dont seem to understand that mc has witness the death of his comrades after fighting RIDICULOUSLY strong dragons in his past life. So, obviously mc has no room for romance because he want to focus on the war. Though, i hope after he achieved his goal he will start consider romance.

Overall: 8/10 because i felt like it.
