My Sign-in system in Marvel(AU)

I'm adding this as a secondary thing cause I thought of another possible function.

How do people feel about a blood assimilation function?

Basically if luck has it and she gets say...Hulk's blood, it would enter her bloodstream, no not from drinking it would just disappear upon interacting with it in the inventory, she would go through physical and possibly sometimes appearance wise changes.

How would you like that? I am genuinely curious because it'd also be a way to boost her more quickly, and unlike my other stories I don't think I'm gonna introduce pet summons or servant summons unlike people really want it.

Also someone asked about the beginning of the story and I admit I wasn't feeling the best when making and kinda rushed through, but at the same time I wanted to give the being a kinda 'you're just another reincarnation person, here's some stuff go' kinda vibe and I hope it kind worked.

Next I wanna mention something that I'll be adding at some point, now I've read my fair share of fanfics on here especially system ones, and a lot people don't like it when a system doesn't have a level up/stat point thing, so at some point, either in my next chapter or chapters, it will be added as I'm trying to think about the best way to incorporate it into the quests I had in mind.

Also here's a question, do you guys want it to be pure MCU? Or MCU mixed with Inhumans, Mutants, and certain things like it?

Next thing I wanna talk about is the 'Soulmate' now I'm not sure if my explanation in the first chapter confused many or if they understood, but either way here's a, hopefully, better explanation: Basically the way I'll have it play out is when my character sees their 'soulmate' both parties will feel it, like something snapping in place and drawing them to each other.

Now I'm not saying it'll he an instant 'wanna bang' kind of connection as the soulmate and Katerina will actually have to go on dates and actually build up that relationship.

Now at the mention of soulmates, do you think I should stick to one or should she have a few? And if so how many?

Obviously I'm not gonna go crazy and give her...say 100.. but maybe more then 3 to 5? Still unsure about it let me know.
