I hope he doesn't just left, but bring his corps to continue investigation later.

I don't know history of China that much and I don't read this "Three Kingdoms" or whatever and any other secondary titles that based on that, so I have no idea if he exists or not, it's a judgement based on that translator note, that he wasn't included. But since you and PepperLegs87 said that, then I was wrong.

So, TLDR this is made-up character that not even included in the stories this manhwa based on?

I think he know/expect that there was a poison, thats why he don't let his disciples to eat that food.

No, Bichir find you first.

I was wondering if author forgot about this technique, this is Genesis that he used against Samyung Goram - one of the strongest monarch in Chaos (chapter 66-71), we also saw him as a skin later in first floor of the Metabus.as a skin.

I have been reading, the problem with contradiction of this theory: "his body is weak, so let him limit his stats, so that he keep being weak."
Instead of: "his body is weak, so he need to be stronger in order to lift restrictions."

What should be done is instead his skill level should be bound to his physique. So that he can use mastered skills only to the level of his body can handle - this would make way more sense to me.

Something didn't add up to that explanation. We clearly know that he trained his physique manually, so his body was trained. It also didn't make sense because if he get stronger stats, then his body would be healthier.
When he used that mana I had 2 theories:
1) he convert his life force into mana, basically shortening his lifespan or
2) he using mana without using system, like magic that Jung Sangwoo tried to do in that monster pit

but then this explanation ditch those options and spill some bs...

Looks like this guy pissed himself even before he meet Jaehwan

Seems to be Yuria was also affected by that seduction (based on her hearts in eyes)

Why does he just don't get rid of both silently? Nobody would suspect him and he would get rid of that annoyance. Alec wouldn't protect anyone, he is only a hindrance. And an egoistic as well.

Ah, I remembering this name vaguely. Still I thought it was more like a place/continent in this abyss realm.

Ok, what the heck with those Monarcs then? When MC was in chaos they were located to the other side. Jaehwan traveled here and he is now in the godly realm. Then I was expecting that Monarcs residing here, but they are not. Where the heck are they? There would be a 3rd dimension where MC will travel later to meet monarcs?

Honestly I can't beleive with all his upgrades how he was not killed anyone in the past, like when he upgraded roots they destroyed so much land and there was no casualties...

Spoiler: At the end of this refinement he is 1-start Grandmaster, during next chapters with hunting for ship key he would be in a traders ship where he would eat expensive fruits and become 2-star. It's about 335 chapter or so. Currently this translation is lagging behind for at least 15 chapters from ongoing.

The author is spineless p**sy. I know it will be coming, so I didn't even cared about that brutality in 50-68 chapters.

It is strange, that you weren't using "tama", because your avatar from Gintama. You should be master of any type of tama wherer it's gin or kin.

in the earlier chapters he make fist out of trunk, so he just morphing it's form into anything

I think it is similar to what in Fire Force Shinra do with fire abilities.
