It's all a fever dream caused by the bite on his arm from the previous chapter.

Possibly the memories of the smart zombie that bit him (I can't remember who bit him, but I thought it was a girl...)

Just like all the other's, he is a Fanatic.

Willing to do anything in his worship of Thananos

Well the most cliched option would be him transforming into a dragon and everyone flying on his back..

She implied that she wanted to, she actually only said she wanted to spend the night with him.

That said, it is most likely a sexual thing, but if it also makes her stronger...

Depends on the Mythology, In some she had no mother, in others Zeus Ate her mother and she was born inside him and then escaped through his forehead.

No I'm saying she might not be fucking them, Just killing them and taking their Yang energy.

I'm guessing the mage looking guy who gave him the teleportation orb is after Garbage and she is a princess or something.

Classic :P

It's not really explained in detail in the novel.

Just that touching the Waypoint records that waypoint and allows you to transport between them.
I'm assuming there is a normal path between floors that you can walk that's a lot slower than the Merchant pathways, but so far in the novel the MC has never tried to take that path.

Might not be 100% sexual, Gotta assume she needs men's Yang to help her cultivate.

?

Only people born in the Tower can become Wandering Merchants or Mercenaries and use their pathways.

As for how he eventually gets around this problem: (Spoiler) There are farm deeds that teleport you to the floor they are on when you activate them

Why Tungsten and not Osmium?

Of course the MC has the same nationality of the Author... He is the Author (He entered his own story)

OOoh, Is he not only Korean but he also read the novel and is freaking out that the Author is there?

I just feel pity for the hell he is about to go through...

Half Brother, Same Father, Different Mothers.

And they and their followers typically hated each other in most stories (weak cowards vs hotheaded idiots)
Eg: Athens vs Sparta.

Yeah I think your right, whoever claims the soul probably becomes him.

I'm assuming he will kill them all and take their runes.

Understandable, I only remembered it because I recently played that Horrible Assassin's Creed game...
