Immortality System: The Last Human's Transmigration

"AuuuuuuughhhhooOOOOOOO!" The creature let out a sky-shaking roar, making the trees around it ruffle and dance while making all the creatures within a kilometer radius freeze in fear.

''It doesn't seem intelligent though...' The snake thought, yet not for a second did it lower its guard in front of this beast, if you could even call it that.

The creature was a complete monster that exceeded in both power and created fear in an opponent. It had countless tentacles and was by itself, much taller than the length of the snake. It had hundreds of eyes that opened on random parts of its body whether that would be the tentacle or within its mouth.

Its body was made out of azure-blue scales mixed in with a few pitch-black ones that stood out under the rays of the sunlight since they would always be the only scales to not reflect any light.

It had no hair but instead seemed to have 2 distinct wooden horns protruding out of its head. The horns seemed sharp but at the same time, they felt dull due to both the texture and luster.

"AuuuuuuughhhhooOOOOOOO!" It let out another roar, yet even though this one was a little quieter than the last one, it still held the same impact on the surrounding environment.

"Sssssstthhhh." The snake let out a low hiss in return for receiving the roar. Right now the battle wasn't about strength, it was about mind games. Who would attack first? Who would lose the advantage of having the unknowns that they could use in dire moments?

Right now, both of the creatures knew nothing about each other, yet that all changed when a subtle booming slamming sound shot through the forest.

One of the unintelligent creature's tentacles hit the ground with an unfathomable power that sent shockwaves through the ground, making everyone within a certain radius feel it.

Countless trees around the creature flew up to the air, some of them having been uprooted from the ground while others just happened to be smashed to pieces, kicking them up into the air alongside a huge dust cloud.

The snake seemed to also lose all care for the environment around it as it slithered through the forest, destroying and creating havoc everywhere it moved.

When it had reached a 100-meter radius from the creature in front of it, it quickly opened its maw and began bearing its fangs towards it before finally...

*Pitu*

The sound of its fangs entering the body of the tentacled creature caused the forest to turn quiet. It was as if nature itself was waiting for the outcome of the clash with anticipation, every second that passed causing it to become more restless.

"AuuuuuuughhhhooOOOOOOO!"

My eyes immediately darted towards the direction of the roar, yet I only did so for a moment since I knew I was about to be attacked in the next few seconds.

However, to my surprise I watched every creature around me freeze in place, eyes wide open and maws left agape in both pure fear and horror. It was as if their muscles stopped working instinctually the moment they heard the roar.

While many of them collapsed out of the shock and the fact that they could not move their body, others stood there like frozen statues unable to even look at me anymore as their eyes had moved to either look at the ground or roll back into unconsciousness.

I on the other hand, while feeling a slight strain in my movements, could still move normally. Yes, sometimes it felt like I was trying to walk through water, but other than that feeling it wasn't too bad especially when you compare it to the feeling of dread I felt almost all the time whenever I fought.

"If I think about it... Nothing compares to the dread that I felt a week before Earth's invasion... Maybe I got a little used to it?" I asked myself before realizing that I had gotten a little sidetracked

Not wanting to waste any more time, I swiftly lunged at an incoming insect and plunged my blade into its head before spinning around and decapitating it with all the strength I could muster.

Without skipping a beat, I once again dashed in another direction, this time plunging my blade into the throat of a wolf and killing it instantly in the process.

[Mission Reinstated!]

[The system has recognized your actions of bravery and courage and due to this, will allow you to redo a mission from your previous life]

"What?!" I exclaimed while barely missing my attack, stabbing a leopard-looking creature in the side rather than in its throat.

[A Prime Tyrannosaurus Ancestor has been detected nearby]

[Mission: Defeat or kill]

[Information: Defeat or kill a Prime Tyrannosaurus Ancestor without sustaining severe injuries. The

[Reward:

-Receive the skill 'Life Drain'

-Instant Level Up

My eyes widened in surprise while my jaw fell out of shock.

'Is it the same one? I mean, how many Tyrannosaurus-Rex Ancestors can there be?'

The thought of revenge had made the corners of my lips curve into a cruel smile. I wanted to avenge my previous death no matter what, and the system had just given me a way to do so while gaining some system benefits.

'If I gain a skill like life drain, I might become invincible. At the same time, life drain can somehow be the weakest skill ever, and since I'm getting it at level 1, I doubt that I'm going to be able to drain the life of a creature in a few seconds.'

With a slightly disappointed sigh, I finally stopped myself from being consumed by the rage that was unknowingly bubbling inside me for the last 4 weeks. Nevertheless, it would be stupid to say that the fire of animosity had been extinguished completely, but only time would tell.

Opening my eyes once again after having calmed myself down a little, I narrowed my eyes and searched the area around me until I saw it.

A faint outline of a silhouette resembling the creature I had fought against a little more than a month ago.

*Boom*

My body turned into a blur of white, black, and crimson red that shot through the forest with a speed unrivaled by any of the creatures around.

[Hp:94/115]

[Mana: 5/20]

*Boom*

I could feel my mana drain out of me for a second, but I was not too worried about that for now. All that was in my mind was all the ways I could end the life of the creature that had killed me earlier, and now that I had been given a chance to do the same to it, I would not let the opportunity slip by easily.

When I finally appeared in front of the T-rex, I quickly halted my movement and landed on a tree branch, looking down at it as it looked up at me.

I could see its eyes widen like saucers while its maw was also left agape due to my appearance.

'Impossible!' It roared through its mind linking ability.

"Tsk." I did not waste another second and stepped off the branch before beginning to plunge towards it with my blade in hand and my rage flaring once again.

The sudden killing intent that dropped onto it like a mountain caused it to stop moving for a second. And that was all it took for me to get the advantage immediately.

When I reached the same height as the t-rex's open maw, a cruel smile once again flashed onto my face. Images of what I had done to it last time crossed its mind as well as mine, meaning it knew exactly what I was about to do.

With the flick of my wrist, I recreated the same scene as last time, throwing my blade into its maw and hitting the back of its throat, making blood spill out while forcing it to drown within that very blood.

Without skipping a beat, I landed on the ground hands first before flipping back and creating some distance by sliding away.

My eyes never stopped looking at it the entire time, but I still couldn't help but quickly analyze its body.

From the black and white vision alone as well as the red that highlighted all living creatures, I could see that the energy within its body was a lot lower than I had expected. Hell, it only double the amount the hippo had, and even then that shouldn't have been the case.

This is a Prime Tyrannosaurus Ancestor we are talking about. There is no way in hell that this creature would have such a small amount of energy.

It was only when I stopped and thought of the situation that I understood what had happened. While I had my suspicions that this T-Rex was the same one that I had fought against and died to, I wasn't too sure. I was simply releasing my anger on a creature that resembled it. Even after it said 'impossible!', I still assumed that it might have said that due to my similarities to the Elves or even the Dwarves that the last T-Rex had talked about.

Now, however, with the energy, speech, power, and similarities I could see, it was difficult to state that the beast in front of me was not the same one that I had fought against before.
