The majority of the series is 9/10, although there is a arc near the end (from around ch. 90 to ch. 115 ish) that drops down the ball in terms of pacing and character development. Makes the series feel like a 7/10 at that point. Still a great series if you're a fan of the fantasy genre and the immortality trope. This was one of my first and still one of my favorite manhwas, and I'm writing this after almost finishing my re-reading. Even with the nostalgia glasses on, this is still a great series with well-built characters, well-designed lore that builds off the protagonist'simmortality, interesting combat/magic mechanics, and fairly stereotypical yet engaging theme of the curse of not dying when the ones close to you pass away.
