It has been 20 years since he came to a world similar to the modern European background. With his early wisdom, Fei Lin learned a skill and finally became a decent person.

Originally thought that he would marry a wife and have children and live this life in a dull way, but found that there is another world under the shadow of the world.

In that world, there are occultists who practice esoteric techniques and master extraordinary powers.

It is weird to spy on humans in the dark and feed on humans.

There are evil god believers who worship the evil god, please the evil god through bloody sacrifices, and exchange power from the evil god.
