[You have died]
[Initiating System Activation...]
Those were the words that rang in my ears the moment my vision had turned black. But unlike others who were thrown into the same situation as me, I didn’t die.

[Immortality System has been activated]

I was thrown 300 million years back in time to an era where the weak were preyed on, and the strong ruled with iron fists. An era of magical creatures beyond human understanding. An era of intelligent creatures that could rule over humanity with the power of their stare alone, and ones who could dissipate a hurricane with the snap of their fingers.

An era with magic and evolution that would allow me to climb to the top…

Thrown into the wild with no one to rely on, I was forced to turn towards the only semblance of hope in this cruel and uncaring world. The only thing that could help me survive this madness.

The light at the end of the tunnel for the last human who persisted until the end.

The only system worthy for the last survivor, and humanity's final anchor. 

[Welcome to the Immortality System. A system that makes sure you never die as long as you work for it!]

Author's Note:
The story will have elements of psychology and will explore the main character's mental health. It might also sometimes have information dumps but I'll try to keep it to a minimum. 

This is not a novel with an overpowered MC. The mc, while being immortal to an extent, starts off very weak and slowly gains strength.

WARNING: For the first 30 or so chapters, the mc is barely survives by the skin of his teeth. Give the novel a chance because the mc does become much stronger from chapter 40 and onwards.

NO HAREM!

Immortality System: The Last Human's Transmigration

As the two of us walked closer to the castle in the distance, I glanced in the direction Klive, and the others went before sighing in exasperation.

A few minutes quickly passed, and eventually, I found myself standing in front of the castle, my eyes lingering on the gate in front of us while the Head General turned to me with a raised brow.

"So where are you from?" He asked, a clicking sound coming from behind him as the gat slowly opened.

"I don't really know. I'm an orphan but the orphanage told me that I was a mixbreed." I explained with a shrug.

"A mix-breed?" The Head General scanned me, and with a frown, he remembered the first time he met me.

While he could not understand why his king would want to meet someone who had not even reached the gaseous stage, he understood that his king was very rarely wrong about his strange feelings, so he would not dare overlook the random man who seemed to have appeared out of nowhere.
