I love this series I do not regret discovering it, I am so hooked on it. I have re-read it like 5 times and it still delivers each time. I promise you will not regret it. If you have finished Solo Leveling, this is the next one you should read. The only downside is that when you catch up to the author, the cliff hangers hurt a lot. you will always be left in suspense and it will crush you and cause your to heart ache. Though once you start reading it, YOU WILL NEVER STOP!
