I was sound asleep in my room one night, but I suddenly felt unsteady and snapped awake...only to find myself somewhere...weird, I was floating in some fluid, the walls against me felt soft...squishy, and I can hear a heartbeat above me...I moved around gently and I could hear gasping and groaning, I was inside someone, who just laughs and spoke in some alien language as they rubbed their belly, with the inflection in their voice, the monologing and the cackle gave off evil scientist vibes, and with a muffled scream outside followed by a dull thunk only confirmed my suspicions.

I stay still for the time being as I study myself, using my tongue...no tongues to feel around my mouth, I felt an odd set of teeth, some were flat in the back, but most were sharp and raked back like normal snake teeth, I then felt 2 fangs, rather long fangs in fact, flexing them a bit they pop in and out but so did my other teeth, oh good I have the mouth of toothless.

But as my "master" goes about her day I focused on trying to understand her language, as the months went by I slowly grew a bit bigger, and I was already starting to figure out some words based on what she was doing. But without seeing what it was I can't really understand much, but I grew tired of waiting to be born normally so I shove at the wall, causing her to gasp as she dropped her stuff and held her belly, I try again and shoved with everything I had, causing her to groan and knelt to the ground, I shove even harder and actually broke through her womb's wall causing her to yell in pain as I keep shoving at the walls as I got into her chest cavity and my thrashing around caused serious organ damage as I try to force my way out.

The evil scientist spits up blood as her skin stretched, I keep shoving and eventually tore the skin and broke out, she just lays there on the ground as I pull myself out of her twitching corps, she looked down with what strength she had left and looked at me, I glare back at her and watched the life leave her eyes, leaving her for dead I sigh and look around a bit and test out this new body.

"Ok, I got isekaied...not sure how or why but I'm now a 6 eyed snake monster with tentacle arms coming off my head, just went full xenomorph on this bitch, and I'm in her home, alone, covered in blood, and I'm starving." I looked around for anything reflective so I can at least see what I look like fully. I found a bucket of water with the sun shining on it so I looked at the water's reflection, my eyes were all a neon blue color, my main color looked to be an olive green with a mustard yellow underbelly. "Well if I had to be reborn as a monster at least this one has a cute face." Using the bucket as a reference I hedge a guess I was about 2 and a half, maybe 3 inches thick, guessing the bucket was about 2 feet tall I fold myself in 2 foot increments to find I'm about 5 feet long.

My stomach growled louder and I wince from the sensation. "Yeah yeah I hear ya! Let me figure things out first....appraisal. How do I trigger it?" I closed my eyes and focused on what I knew about isekai lore.

<Acquire Skill [Appraisal lv1] for [250] skill points?>

I nearly jumped out of my skin when the system's voice popped up and I squirmed a bit before I collected myself and sigh. "Fucking hell! That scared the shit out of me! But yes, let's get appraisal."

<Acquired Skill [Appraisal lv1]. Remaining Skill Points: [99,750]>

"I have that many points for my starter pack? Even if I have that much I better be frugal with them, for now let's focus on improving my appraisal skill. Now...I got concentration and memory by focusing and trying to remember what I knew, so logically that means using appraisal on things would improve it as well." I focus on the dead body.

"Ok that's better, now to get tele-" I was cut off when I heard a bunch of shuffling in the wall and I focused on tracking it, I could hear squeaking, must be this world's rat analogs.

<Proficiency has reached the required level. Acquired skill [Auditory Enhancement lv1]>

I followed the sound to a hole in the wall and getting in, climbing up as I followed the scent, once in the ceiling I saw a rather large rat about the size of a corgi, I blinked as I appraise it.

I decide to hold off on getting more for now and slowly creep up on the skaven rat, being as stealthy as I can as I get ready to strike. I inch closer to its neck and when it's rubbing its face I sink my fangs into a major artery and start pumping venom into its blood while quickly wrapping around its neck and chest to try and strangle it, putting everything I had into this as it thrashed around, it's health bar slowly getting weaker and weaker the more of my venom I inject, I squeeze even harder every time it exhales and eventually it can't breath enough to keep fighting me.

Finally it was so weak it couldn't fight back at all now, so I start walking my mouth to the rat's face and I just let instinct take over, unhinging my jaw and working my way down it's body, but It wasn't fully dead yet and kicked, despite this thing being a rat it actually tasted rather good.

I made soft glucking and slurping sounds as I worked my prey down, with it being so much bigger than I was my hide was stretched more than I thought it could, I felt tight but I manage to slurp down the tail, I groan but before I could start digesting another one showed up and seemed pissed, this was a level 5 female, I stay still as she moved closer, without thinking I grabbed onto her head and sank my fangs into her skull, she squealed as she tried to pull her head out of my mouth but was rapidly losing health, I figure that was because I was injecting poison into her brain, I start swallowing her down as she grew weaker and weaker, my stomach gurgling and groaning loudly as the bulge shifts about, my hide being so stretched I felt like I was gonna rip myself open.

With significant effort I finished her off and heaved a bit, but managed to keep my food down, but I felt so sick from this, so I just lay there as my stomach tries to digest the 2 giant rats without bursting, my red sp bar, which I can only assume is my stamina, was pretty much empty which explains my exhaustion.

"Woo hoo....that's...a lot...of stuff to remember. I'll...do more...after a nap" I just lay there and fell fast asleep, the constant noises of my stomach actually help relax me into a very deep sleep, my skin sheds as I grow a little larger, already I was dreaming about food.
