我在人间立地成仙

No it was mentioned that how rei is A but that the highest evaluation that association can give and her power is beyond that.

I forgot the name but the some ghost legends in Japan are like this, some old and neglected things transforms into ghost.

Finger licking good

Referencing the anime and manga kind of breaks the immersion of the novel.

Just cut off their legs

Why does this overlap with agility

He also immortal even without the dengeon because of his title so I don't know why he is freaking out.

It would have been funny if author had used the infinity war reference with him killing other zombie like two zombie standing together at edge of the cliff and MC say "sorry little one" and throws the other zombie.

So he was supposed to get system before he died or was it just system being slow.

Kind of make sense in context of the story/plot to get physical improvement genes but the genes he got are too trash like the finger improvement, its not totally useless but it's literally can be replaced by an guns as they do much better job than an half assed ability but it does make sense as MC probably won't able to get his hand on a gun but he won't knows unless he tries right, buying one for protection is not wrong for an student who has an accident before. The leg ability has its merit for both casual and life saving moments but its just for one leg which makes it not worth it. Also I can't describe MC luck as I don't know if it's ridiculously good ridiculously bad because there should be many negative effect gene out there but there should also some good one so I can't tell without seeing other characters gene to tell if MC got an good deal.

This is the most logical decision but I wanted see psyonic abilities . Leg ability are too lame.

We call that plot armor

Why not mention this when he was planning to run away.

So initial impression is okay, grammar is good. Not the best start as comedy is not my cup of tea but okay, transmigration explanation was unnecessary in my opinion as having some mystery around it would keep the readers guessing while coming up with their own explanations. Same goes for the destruction of the universe where the universe doesn't even feels like an universe (I know) because it's too small, probably like size of an solar system (which is still quite big) but an solar system is just an tiny insignificant part of the universe that we live in so it's like an ant trying to destroy the earth it doesn't make sense even for most fantasy gods their powers at most can destroy planets which the "the world". It would have made sense to use dimension or realm rather that universe as it is more believable. This just some suggestions as it's author's novel he gets to decide what the universe is.

Multiverse is unimaginably big like take dnd for example the are uncountable amount of world in Multiverse so it doesn't make sense to one up this also if this was an fan fic then it would have made sense to have an omniverse. Also very few stories can reach the Multiverse without being trash power fantasy.

So does the parasite like like her or the previous host just liked her and that is explained here.

That why I saying he should show his talent in creation might get some good resources

I already don't like this two characters first of all both their mindsets are trash, as talent, background, ect arc secondary things in immortal path rather the willpower and the Dao heart is that matter the most, if are reliaing on other thing then are 'not enough to reach the apex'. Second thing both them look down on other you might think that Lin seem modest but pride is deep in her bone it is just she is humble brager, just here this chapter you she gave that material skill to him with her insights in it then are you saying Mc don't have what take to master the that which already public like at most it just less the time he need to master it And our native MC will be probably be very impressed by her and will praise her every two chapter or so.
