"No, no, no, nonononono" I can't believe it, i'm a fucking monster!?

CONGRATULATIONS, YOU HAVE SURVIVED THE FIRST ROUND. THE BARRIERS WILL FALL NOW.

Wait, what? What barrieeeee... Okay THOSE barriers. I was dumbfounded as i looked to the sky, I saw big red glass-like domes breaking one after the other, when the one i was on broke with a 'pop' i could start hearing screams, so i did the first thing that came to my mind. I climbed a tree.

"GYAAAAaaaah?"

Shit, it's another one of those, i don't think it can see me from here.

As if to prove me right it started looking left and right, and seeing no one, it just took off runing and screaming again.

"GYAAAAAaaaaaaaaaaa..."

Okay, it's gone, but how the hell do i get out of here? Think ,think, think... Wait. First round? Hung*r games? So this is a battle royale kind of competition and the first test was a one-on-one? Alright, i can work with that, now the question is, short-term or long-term? If we are supposed to get out fast i need to follow the survivors, i can go stealth two or three days tops so i can wait and kill the last one when it is exhausted from battle. But if we are supposed to be here weeks i need to find actual shelter like a cave and procure materials, make traps, i can play it slow then. Wait, no, i don't know how this place works, how their... OUR body works, do we even need to eat and defecate? This IS hell, i need more info...

As i was climbing down the tree to inspect the corpse of the one i killed i realized one thing. It isn't there. The corpse had dissapeared, i hadn't seen the other carrying it and no other had come after so... It dissapeared? What the fucking fuck? How? What? WHY? But if we are souls and it dissapears after being killed then, what? is this time definitive or? Fuck. Okay, it's decided then, follow, and learn. Last one went past there so...

I went after it at a moderate pace, i don't want to tire and don't know the endurance this body has so a slow jog should do.

After a couple of minutes and gradual increase in volume of the screams i finally make it, it's a cliff, there is a group of them surrounding a portion of the cliff in a clearing from the cliff to the forest, at a distance of each other, i stay in the forest and climb a tree in the second outmost line, and wait.

"GYAAAAAAAH"

Another one comes and starts attacking the one nearest but stops suddenly when it sees everyone staring at it, it stays in tension.

What are you all gonna do now?

Surprisingly enough they just move a bit to make room for the newcomer. When they move i see what they are surrounding.

A cave, but just what is inside...
