The Last Human Returns.
Prologues

A man who had no arms or legs, was sitting on top of a Mountain created from the hundreds of thousands of corpses of Monsters killed by his sword.

"Huh ... Huh ...." His condition was so severe that breathing was already difficult.

Brucks.

Falling down helplessly, the man looked at the sky that was losing its blue color. A red sky reflected in Mera's eyes that looked like ruby gems.

"... It's over." There was no emotion in his hoarse voice.

After a long painful war between mankind and the Monsters, it is now over with the deaths of the 7 Great Disasters, the Devils who lead the destruction on every Planet they encounter.

"Although so .. extinction of mankind is inevitable."

Being the last human alive, his heroic story that killed the 7 Great Disasters could not be spread. Ethan Austin, the mortal who defied the heavens. His name will be buried with the destruction of the Earth.

Ethan could only laugh bitterly, self-deprecatingly struggling so hard for such a stifling moment. Instead of feeling relieved, there was only sadness and loneliness that filled his heart as the last human-living being left.

"I wish I had tried harder and not played around." His hoarse voice whispered to no one. He just wanted to complain, taking out all the burdens of thought that had been stored all this time. "If only I had a second chance .. will everything change?"

Ethan's murmur and grumbling may be heard by the Universe or the Gods. Just then, a pop up appeared before him who was already preparing to accept his death which was so lonely.

[Experience Records count delayed due to external interference.]

[With the will of [Supreme Being], you will be sent to the past.]

Ethan's pupils widened looking at the unexpected message. "Wait on! What does it mean-"

Before he could ask any further, his consciousness slowly began to fade. The scene where the red sun set on the western horizon looked scary and beautiful as his last memory.

***

"Huh!?" The boy with black hair and red eyes woke up with a body full of sweat. His lips were pale as if he was seeing a ghost.

Pensively, the boy who was beginning to calm down looked around. His expression became crooked when he saw the familiar space around him.

"... This was my room 20 years ago, wasn't it?" He muttered.

Although he was not sure, the boy still remembered it. Room with some posters of two-dimensional female characters that she likes. Then, an old computer that he used to play games and spend time.

"Also ...." The boy's gaze was fixed on the Katana stored in the sheath, tucked away in a dark corner of the room.

The boy got up from his bed and walked up to Katana. By biting her lips, she raised Katana with one hand.

"... My first katana, [Black Lily]."

Pulling out the Katana from the scabbard, the boy then took a prepared stance. After taking a breath for a moment, he suddenly made a slash move.

A slash!

"It's not very good." The boy made a comment that would make every Swordsman cursing in annoyance upon hearing it.

According to the current standards, the Sword Science he used was already at the top level. Winning 3 International Swordsmanship Major Competitions was a living testament to his talent. However, his half-and-half talent failed to bring salvation to Earth.

The boy, Ethan Austin, stroked his chin. "I'm actually having regression, huh?"

Though he initially thinks all of this was just a flashback before his death, Ethan becomes convinced that he is now back in time before Earth went through an invasion.

"I'm sure it has to do with the System and the [Supreme Being] mentioned."

Ethan doesn't know who [Supreme Being] is. However, seeing him able to intervene in the Akashic Records made Ethan convinced [Supreme Being] was the closest to the concept of [God] itself.

[You have achieved an incredible achievement.]

[As a gift, you get: Seed World.]

[Your Experience Records changed to Karma.]

[You get 1,000,000 Karma.]

A barrage of pop ups appeared in front of his eyes which made Ethan flinch. The interface screen with a familiar look makes Ethan sure everything he experienced is not a dream.

"... Even so, this is overkill." Ethan smiled bitterly at the gift from Akashic Records.

Karma is the currency that will be used to buy goods in the Shop System. Once the Dimensional Barrier was destroyed, the banknotes would lose their value. The comparison of paper money with Karma at that time was, 1:100,000. Sure, in USD.

Putting aside karma, Ethan was more curious about [World Seed]. This was his first time hearing about [World Seed].

[Seeds of the World]

Description: A Seed that was the beginning of a New World. The speed of growth of the World depends on [Mana] supporting the core of the World.

]

His body gasped as soon as he read the description of the item that seemed unbelievable. He blinked and rubbed his eyes before reading the item description once more. But his writing has not changed.

Ethan's jaw dropped to the floor. "... Seriously. This is too much."

Ethan felt a chill in his spine. Profits come with responsibility. Ethan does not believe in pure goodness.

"... Does, [Supreme Being] want something from me?"

Ethan's mind is full of speculation. However, without any clues, it was impossible to find what Supreme Being wanted from him.

"Let's think about it. Now, there's more to it than that ...." Ethan clenched his hands tightly. The leaking killing intent made the space creak as a result of the pressure from it. "7 Great Disaster .. This time the end result will be different."
