Ok I know I rated this a two, but I have to get this off my chest. The first 100 chapters? Absolute cinema. The start had me hooked and excited. The Barbarian Arc was easily the peak. Aiyen and the Balak tribe gave the story so much soul and stakes. I was ready for the legendary  run this manwha would do, but man, did the author really dropped the ball.

As soon as the School Arc starts, the story just… dies. We went from a dark, revenge plot to the most generic, bottom tier tropes you’ve seen a thousand times. Commoners vs. Nobles? Sure why not. Hiding his power for no reason? It can't get worse than this right?. Endless, boring school tournaments? Need I say more.
I could’ve forgiven it if it was a quick 20-chapter detour, but finding out this "academy" nonsense is basically 50-60% of the entire manhwa? My patience is already cooked.

THIS NEXT PART CONTAINS SOME SPOILERS

And it gets worse. It stops even trying to be its own thing and turns into mid tier Tower slopwith a Solo Leveling-style system and "Class vs. Class" battles that nobody asked for. Then just when you think he’s finally going to do something he goes to prison, fakes his death, and hides his powers for another 100+ chapters.

SPOILERS END

It’s like the author forgot the title of their own book. It’s called Revenge of the Iron-Blooded Sword Hound, not The Constant Hiding and Pointless Schooling of a Professional Time Waster. If you loved the barbarian arc, honestly, just stop there and imagine he lived happily ever after, because everything after is a snooze fest. Overall 2.5, can't be bothered to continue this slop.
