Refine demon spirits, and soar through the sky and burrow beneath the earth!
In the modern city, spiritual qi revival means humanity is no longer the master of civilization.
Back then, sunlight could no longer be seen through the sky, which was covered by flying beasts. The ground was stained red with blood, and humans had become strays and prey. It was a true living hell. Humanity only escaped extinction on the day an ingenious martial artist fused the demon spirit left behind by a dead monster into his dantian.
By refining demon spirits, people could gain the ability to fly through the sky and burrow beneath the earth like monsters. A man who had already died returned to the age of eighteen because of a monster.
That day happened to be the annual Demon Spirit Awakening Day.
That day, he refined an evil spirit...
An evil spirit: an ominous, wicked presence!
