All together, it took about 18 hours dissecting the entire corpse and setting each piece of it aside. It was shorter than expected, but this gelationsourace (self-named) was mostly liquid weight, or maybe jelly weight would be a more appropriate description given how vicious its blood substitute is. It would have been even quicker if various creatures had not attacked or tried to attack him during this time. However, such attacks gave him more insight into the strange bioweapons that inhabited this world, so he wasn't upset.
First off, they just appear at certain points and distances away with no indicators of their existence before that point. His best guess was that they normally lived in another dimension layered closely enough to this one to sense energy from it and cross over whenever they find a source of power they want to consume. The process of coming over can't be easy or done anywhere though; otherwise, they'd just spawn right next to him and attack immediately all the time. This also explained why, after the hooved panther first appeared out of a cut in space, it never tried to retreat and try for another surprise attack.
The next insight he gained was that these things fell into two categories: those who were weird by the standards of his own world and the laws of biology there but made logical sense, and those who were just plain silly. In the first category, you had things like the gelationsourace. While the fact that its lower body was made of a Newtonian fluid and its insides were mostly really thick blood was weird, it at least explained how it could support its own weight; bone density isn't a problem when you don't have bones after all. In the next category, you had the monsters who defied any logic or sense, like the flying cat head or more recently the worm swarm. A single normal-looking small worm that could crawl through matter and multiplied if burned or cut in half—that thing, those things, were a pain and a half to get rid of. Unfortunately, he hadn't gotten to study any of the latter type of creature yet due to them all dying in ways that didn't leave behind a body.
The biggest and most relieving revelation though was that the vast, vast, vast majority of these bioweapons would die just to his heat shielding being turned up to max, and the few that could survive that would die to his flamethrower. The gelationsourace and hooved panther being exceptions to that rule all but confirmed that, given the small amount of energy he was leaking relative to back when he had his core out in the open and just blasting out power, would only attract lesser bioweapons, while the big fish focused on searching for larger power sources and conserved energy otherwise. If it wasn't for that, he'd be forced to abandon this corpse entirely and just hope he could make it to civilization without being destroyed before he left the forest.
He looked around at the dissected and organized parts of the gelationsourace and decided to record his findings before he got to work making them into something useful.
"Audio record start"
"The autopsy of the creature designated 'gelationsourace' starts now.
Total weight: 44 tons, less than half the expected weight of a creature this size, especially given the earlier ground shaking it caused. I suspect previously noted life force energy is also being used to enhance the creature's strength and provide additional abilities instead of just powering it.
Dimensions: 80 ft tall, 30 ft wide, a normally impossible height for a land-based organic creature to reach but one made possible by the creature's unique blood and legs.
BLOOD: The creature's "blood" is a thick jelly-like pseudo-solid that pulls quadruple duty as its muscles, blood, bones, and heart. Given how thick it is, it's unlikely that it would flow; instead, I suspect that the blood remains stationary and directly produces everything they need on-site using life force—it's the only way this makes sense. Also, it's extremely heat-resistant; despite being exposed to maximum heat shielding and my flamethrower multiple times, it sustained virtually no damage, although it did still transfer heat as expected, scorching the ground beneath it.
Brain: It was reduced to irradiated ash and was not able to be examined.
Skull: The only source of bone found, it's thicker and more dense than would be expected, and there's a hole in it where my spear pierced. But outside of that and its extraordinary heat resistance, it's as expected. It was also much, much, much smaller than expected, but that was because it only seemed to protect the brain and composed no other part of the monster's face.
Legs: Perfection—these four beautiful masses of perfectium (self-named) are perfect. Heat-resistant, impact-resistant, even somewhat stab-resistant, although not to the degree of its other near immunities. It acts as a non-Newtonian fluid should, only better in every way. I wish I could take all of this with me back home for use in the great war, even if only to see what could be done with it using our forges. Absolutely no idea how the gelationsourace managed to control these things; there's no BLOOD in them, but they were attached to the creature's body as legs normally are. My suspicion is that they were also controlled by life force, but they give off no signs of such energy.
Fur: Aside from the near immunity to fire and heat, it also has no opening of any kind—no pores of any kind. The fur functions more as a container for the BLOOD than anything else outside of its heat resistance; its resistance to physical attacks is mediocre.
Internal organs: All function as normal and are as expected, protected by a barrier of BLOOD.
Tusks: The silver tusks are each around a meter long and perfectly straight with no curve. The silver tusks are of similar durability to an enhanced titanium block back home despite only being
