Earth, thousands of years after the apocalypse.
As ghosts with terrifying power descend and destroy the world, countless technologies and achievements have been lost in the long river of time.
In the following thousands of years, human beings rebuilt civilization again and again, only to perish again.
No one remembers the past.
No one remembers the glory that mankind has achieved.
Today, everyone lives in a world ruled by ghosts.
-----
A boy with amnesia wakes up in the most dangerous area of the Red Fungus City - the Fungus Zone.
The boy gradually grew up and passed the examination to become the high-status Zephix extractor - a special professional who can harvest the power of ghosts.
Unfortunately, the power of ghosts has long been parasitic in his body, so he has lost his qualifications for the job.
At this moment, a mysterious man suddenly visited.
The gears of fate finally began to turn.
