In this world, orphans or just anyone without any hope for this world can apply to become a “walking target”.

These students need “walking targets” to test their training on living, walking beings of flesh and blood.
In exchange, they will be provided with food & shelter.
Their existence value is lower than a slave, but if they manage to survive a few years they can receive a life long pension.

Xiao Han is such a “walking target”. One time he witnessed a powerful Demon Hunter disposing a demon. When the demon died, a fragment of the demon that managed to escape entered Xiao Han’s heart. No one saw that, and even Xiao Han himself only felt some discomfort for an instant.

But that thing in his heart soon gave Xiao Han visions, and the first one is of a cultivation method which allows Xiao Han to absorb damage to enhance his body. A perfect cultivation method for a “walking target”.

She was reborn back to 11 years ago, when everything was fine, her family was still alive and she had not experienced the pain of destruction. Since she had the chance to restart, she decided to seek revenge on those who had hurt her! She would also leverage her knowledge and strength to lead her family to a prosperous life. However, she has a regret: despite being reborn, she still ended up marrying him, a man who was difficult to approach...

Mystery is the nourishment that keeps me from being ordinary.

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.

There is an evil god who wanders outside the world, peeps at the world, and only infiltrates the power of scales and claws, which is enough to cause people to fall.

With the mystery as nourishment, he is no longer ordinary after 20 years of ordinary.
