An Individual from Earth finds themselves in the Shinobi World, equipped with a Scientific System. From that moment, he delved into scientific research far ahead of its time.

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.

Oh, whatever, now that it’s come to this, the only way to survive is to raise the male lead into a sane and stable adult! The first step to avoiding death by the hands of the tyrant male lead is changing this extremely frightened child’s life.

“It must be very inconvenient for you to have me suddenly show up on your doorstep, I’m sorry. You can tell me to go away, I’ll be fine.”

“Nonsense. Do I look like someone who could be inconvenienced by a little boy like you? Also, what do you mean by you’ll be fine even if told to go away? It’s not like you have anywhere to go back to, kid.”

The little boy burst into tears.

‘Oh, this is so not it.’ Was what the witch thought to herself as the little boy sobbed
