Sci-fi and mech are the main parts of this novel. Enjoyable but very confusing. Especially in the medical aspects. They can 'cure' broken bones that are smashed to dust or mutilated body parts but can't come up with regenerative medicine to repair body parts or even throw in bionic eyes for the blind?

Being xianxia, there isn't one possible way to like you know, regrow a limb or two?

Funniest thing yet is that when it comes to xianxia, the thing that pops up into my head first is 'ALCHEMY'. Sure there is artifact creating which is literally crafting and refining but blown up together with modern manufacturing and sci-fi fusion. Probably since the author emphasizes resources are not enough, things like pill concocting probably got replaced or is simply nonexistent.

Too much logic problems and logic armour throughout that it becomes really mind boggling when the author adds more information or brings up new concepts that are used in the weirdest ways.
E.g. those 5 types of cultivations... zzz

and the competition arc is starting to pick up. Unlike normal Xianxia, 40MC has the protag being looked upon favorably by some major powers, and one of the cliche "I'm better than you, you trash" characters is getting her eyes opened.

When it doesn’t terrify me, I actually like the “nationalism” in this story. Partly, that’s because it’s not nationalism: nations are forgotten, and no area of people seems to think it's better than another area. It's actually humanism. And partly, it’s because it’s reasonable for it to exist, and is a major building block of the story. In the setting, humanity has just recently freed itself from its nonhuman overlords, and is still in the shaky process of establishing its territory and beating back the monsters. Of course the Federation will propagandize how humans must stay united against everything else. The result is that civilians are in awe of militants and soldiers who have gotten injured fighting for humanity, while soldiers in turn are willing to sacrifice themselves to protect the civilians. It makes for some emotive and awesome scenes. But it’s also likely that the MC will someday be forced to realize that non-humans aren’t automatically bad, and that humans aren’t necessarily in the right. We’ve had hints of that all along.

a young female author gives him a pair of novels to read. He forces himself to skim through the Shoujo one. Then he turns to the second, realizes that it's BL, starts sweating, and ‘Nope!’s out of there.

He survives an attempt from a ghost of an expert cultivator to spiritually possess him and has spiritually grown a lot because of this. Not nearly enough to be a genius but simply to have the ability to eventually bridge the gap between him and the geniuses, which is far more logical than to become a genius amongst geniuses just because of one simple fortunate encouter.

Technological items such as a 3D hologram projector which fuctions as a 3D television to watch the news and other entertainment has a lot of small technical parts and is powered by cultivation resources such as Glyphs and Runes.

There is a whole market system based on the development of new technology/magical items where for example the stock prices of certain armor refiner sects goes down because a new improved flying sword has been released by a flying sword refining sect. This type of detail for economics and global market workings you will find reoccuring in almost every other aspect of this world and is in my honest opinion praiseworthy.
