The MC in this one undergoes the horrible experience of being forced to become a merciless killing machine. He had to kill dozens of other children only to survive. This has consequences both for him and his sense of self and for the bastards that did this.

The first arc is the training arc, the second arc is the revenge arc. The third arc is about him trying to reorient himself in the world after survival and revenge are not his only goal. Of course he is too powerful to be left alone and tragedy strikes again, but not to a ridiculous degree yet.

This isn't a happy series, but it is action packed and has many moments to satisfy the blood thirsty. The MC is really the type not to take shit from anyone, which is fun, but he isn't vicious or needlessly cruel. He probably killed innocent people, but not for fun or to make money.

Really trash.

The story starts off unengaging and completely unoriginal. Had the MC been killed and reincarnated, I'd have sworn this was a Chinese copy!

After 7 years of supposed training, the MC and the remaining kids - now around age 21 - head out to their mission, only to be betrayed. Rather than take revenge against those who put him through hell for 7 years, or those who betrayed him, MC illogically decides to complete the hit.

Yes, it's dumb and readers are calling this dude "clever".
The already androgynous MC (I thought it was a girl until someone called him, "he" in chapter 12 or 13) then becomes a blonde, tall, meta-tranny, the artwork turns to crap, he kills a room full of people because they joke as to his gender... it's just AWFUL.

I'd have given this a 1 if the Heavenly Demon rip-off & betrayal arc wasn't mildly entertaining.

Dropped and never going back. Avoid this over-rated stinker.

Starts out cliche but a bit interesting as long as you don’t think too hard about it. As soon as the origin story is done, it turns into grrr! Argh! Rampage! Teeth! Gah! Blood! — Not in an interesting way. The MC is massively op, has powers for no goddamn reason whatsoever, and looks…. Just so stupid. I mean so, so, so stupid. Jesus, but he looks stupid.

super average, kind of bad even. i dont understand why this is so hyped. this manhwa feels so amateuristic, the storytelling feels surface-level

Just drags on and feels like your getting your knee caps smashed for hoping something interesting to happen

Pyo Wol isn't a tasteless brute.

Revenge is a dish best served ice cold.

Comion? Moderation? Morality? Self reflection? Who's she?

"An eye for an eye will make everybody blind?"

Hah. So, what?

No faction or person in this is anywhere near "good" or even "good enough". There's no one to root for. No one.

Amazing.

Finally, a story where the MC really IS as ruthless and as cold as a villain protagonist should be. The only reason he's not just a straight up villain is because everyone else is just as bad if not waaaay worse than him, and MC is...uh...not a nice person.

He has no redeeming qualities...except the barest minimum of courtesy he very, VERY rarely shows to anyone. Safe to say that if he's being "considerate" the person he's showing manners towards is 100% dead.

the writing is like your imagination right before you head to bed. it's not detailed and it feels like they just meh when writing it. the characters are bland and flat.

Mc is supposed to be smart, but is he really?? For example, right after the failed mission. he could've used the girl's face as a disguise(the one that slept with the womanizer), yet he had to go that far to use a random farmer's face just to get caught and make things complicated. he wouldnt get caught if he disguise and escape on the spot.

addition to that, they kept adding in unnecessary information to readers for the sake of drama and emotions. it may leave a bit of impression to readers but itll be forgotten in the next chapter, needless to say it didnt give a big impact to the story.

maybe the author is not at fault here, but the adaption is so bad.

Overall this is quite good but i feel that at times this is uselessly dragged, i think this is because author made our protagonist too powerful. For example : Some characters that our protagonist didn't finish off when he could, came back biting at him later or when our protagonist could have settled issues if he just explained or be a little more communicative (well can't be helped since this is in his character).
So far it looks like our protagonist is looking for emotion/human feelings (my personal opinion). He looks quite apathetic and detached most of times. Unlike other assassins, the protagonist possesses not merely great assassin skills but also great martial skills. He is also smart and have a good memory. For example he can decipher coded message almost instantly or memorize content by simply flipping books.
Appearance wise he is often described as more beautiful than any woman. His body is emanating an odor that make women feel hot. The more intense his feelings are, the stronger his body odor is (mentioned at c41 of the novel but it seems author forgot that point? Since if this is true he can be easily tracked down by assassins by following his odor). He had undying energy and sxual desire. So unlike other works, our protagonist here is sxually active.

For those who are curious if any other assassins survived :

The answer is Yes. One of them reappears at chapter 294 in novel.

First part really interesting, second part boring slow and inconsequential, recomended up to the fall on the vipers nest. so? rated as an 8 then a 2.. so average is a 5.
