Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory?

Earth, thousands of years after the apocalypse.

Countless technologies and advances had been lost to time as the Specters, horrifying beings with terrifying powers, arrived and destroyed the world.

Over the coming thousands of years, humanity had built itself up but always died again.

Nobody remembers the past.

Nobody remembers what humanity had once accomplished.

Now, everyone is living in a world where the Specters reign supreme.

A boy with amnesia woke up in the middle of the Dregs, the worst part of Crimson Fungus City.

The boy grows up and manages to become strong enough to pass an exam for one of the most prestigious jobs in existence, a Zephyx Extractor, someone that can harvest the powers of Specters.

Sadly, he had already gained a power from a Specter in the past, which made him ineligible for the position.

But then, a mysterious man visits him.

And his luck finally turns around.
