Yes, the ML is the person made from MC (not MC per se but ummm like ML was made bc of MC would be more suitable I guess), basically like ML has the character that MC likes or type that suits MC. This hints actually really explicit like sometimes MC always said something similar to "This person cold and soft side is always hitting my softspot, his existence is like made esp for me" (ofc not like this but kinda same talking about "personality that just click and suits MC")

If you haven't read the novel I said above, it's gonna be a bit difficult to guess at first, because the MC said it casually, not like foreshadowing imo

Regarding how ML can exist? I leave it to you to read or just read Kassandra bracket spoiler :)

Back to the start, basically to the lowest level of black tower, not back in time (this is important).

Excluding to the fact that ML isn't a real person (he can be considered NPC at some rules, even tho he's born bc of MC) both of them starts together early and climb up high to the highest level, but sadly, just like, maybe you guys already guess, something happened there. The tower makes ML's replica so in that instance, there are two MLs and MC's make some mistakes (got fooled by the tower) (f*ck I REALLY FORGOT WHAT HAPPENED AFTER) but I remember before they got annihilated (supposed to be), MC or/and ML hide their own memories in some thing, ML in the neckales, MC in the...i forgot the name but it's a property, like holy property? you will know later AHAHAH it's the property that broken into pieces, later MC and ML will go to the school instance, if you already on this instance then this is the property that I mean :)

Actually MC already become a legendary big boss in the tower and he also have a powerful guild

It all started with a bet. You know if you know it. (｡•̀ᴗ-) ✧

I'm shipping Lin Zhen and Yu Feizhou.

Of course, I'll spoil a bit, hehe. There are actually two consciousness of the black tower. One is the good, and the other bad. It was formed by the player's bad and good emotions.

And Yan Wei, he have a prop that can cut and fuse. He used that to cut the good consciousness of the black tower. It resulted to Yan Mingguang.

That's why Yan Mingguang always appear to be his ideal type. Either in physical appearance or Yan Mingguang's pure kindness that he wants to have.

I personally don't really like the last instance, because the plot seems too cheap for a final arc, but I think its still fine and okay.

When it was almost nearing the ending, there is theory which said that there was a possibility that people's hatred were created more than one tower, there also a theory about possibility that there had been people who already defeated/destroyed the tower before, and the tower that MC and ML enter just another new tower which appears after the previous tower got destroyed.

For me this like the author just want to milking this story.

and they communicated telepathically and had to be tied together uwu
