A long time ago.

There is such a group of people.

They have a curiosity and insight that is unimaginable to ordinary people.

With the help of that keen insight, they gradually discovered some phenomena and laws that were different from the common sense of the world.

As they continue to explore these phenomena and laws, they gradually become aware of the existence of a world that is completely different from the world in which mortals live......

They believe that the world is inaccessible to mortals.

It is the abode of the immortals high above, the nine secluded places where the yellow springs flow, and the place of constant contradictions.

And gave it a lot of names.

The fairy world, the underworld, the pure land, the vacuum hometown......

Now, it's known to the world as the "Illusory World."

It is rumored that the secret of immortals and immortality is hidden in the fantasy world......

Therefore, throughout the ages, the world's pursuit and exploration of the illusion world has never stopped.

The "invisible technique" is a method that uses the hidden knowledge from the illusory world to pry the laws of the world and perform incredible techniques.

And now, Jiang Ge suspected that the shadow he encountered was the creation of the formless technique.

No, no doubt.

It must be the creation of the invisible art.

And it is the most troublesome of the intangible creations.

It's like a sword can't hurt a disembodied goblin.

Normal physical attacks don't work against that shadow either.

It was only during an attempt that he discovered that the light of fire could stop the shadow's movements.

And only the light of the fire can, and the light of the electric light has no effect at all.

Maybe sunlight should work as well.

Because that shadow never appears during the day, it disappears before dawn every day.

Sitting in the cafeteria of Longgong University, Jiang Ge thought while chewing wax and dealing with the food in front of him.

"The fear of mortals about the invisible art is not because of its destructive power, but because of the strangeness that ordinary people cannot understand."

This is the content of a book he interprets.

Originally, he didn't quite understand the meaning of this sentence.

Now he felt like he probably understood.

It's not that he didn't think about asking for help from other people or even the authorities, the problem is that no one but him can see that shadow.

His report was obviously perfunctory, and he has not been heard back to so far.

Some people around him thought he was ill and hallucinating.

There's even a stupid... The good Samaritan recommended phlebotomy to him.

"So, now the only way I can deal with that shadow is the invisible technique that also comes from the Illusion Realm!"

A fierce look flashed in Jiang Ge's eyes.

"Teacher Jiang Ge, are you going out?"

A familiar voice came from beside him.

Jiang Ge followed the voice and looked.

A young man with glasses who was bald at a young age and had the demeanor of a big man sat beside him with a dinner plate.

Wang De, a lecturer in literary history who was recruited by Ryugu University with him this year, is five or six years older than him, but the relationship between the two is okay.

"Teacher Wang De." Jiang Ge nodded, in response, "There are some things to go out and deal with." ”

Wang De looked at Jiang Ge's face and said with concern, "Teacher Jiang Ge, I heard that you have been on leave for several days......

Seriously, if the doctors in the hospital really can't cure you.

Then why don't you try the phlebotomy I told you before, it's amazing, I had hemorrhoids last time......"

The corners of Jiang Ge's mouth twitched slightly, and he said a few vaguely, "Hmm... Thank you, I'll try it if I have the chance. ”

Then he shoved the rest of the food into his mouth in a few bites, picked up the plate and ran away without looking back.

Yes, this teacher Wang De is the fool who recommended bloodletting therapy to him... Good Samaritans.

Nice and helpful people who like to try something new.

In recent years, with the Empire's invasion of the Second Mountain and Sea, some strange customs have also been passed down there, including this bloodletting therapy.

According to Wang De, once he had hemorrhoids, he was curious to try it, and wow, it was really cured.

Jiang Ge didn't know how to cure hemorrhoids by bloodletting.

But he was not sensitive to this.

He was blinded by that shadow, and then bled the whole thing.

That's not a direct ascension.

Leave Ryugu University.

Jiang Ge got on the train to the shopping street.

Ten minutes later.

Shopping street.

"Hostess, have you arrived with my pre-order?"

Jiang Ge came to a flower shop and asked.

"It's already here, take a look, guest, it's all just picked this morning."

The proprietress took out a small wooden box and handed it to Jiang Ge.

Jiang Ge opened the wooden box, and inside was an ice pack for freshness preservation and a small bag of white flower petals.

It is a laurel petal.

This was one of the materials for the invisible spell he was going to perform next.

Confirm that there is no problem.

Jiang Ge nodded, paid and left.

Then he walked around and down to an old grocery store in the dark depths of the shopping street.

The owner of the grocery store is a middle-aged man with a treacherous face.

"Guest, it's really unfortunate, the five-color glass you want, it's out of stock over there, I bought a batch of new goods from other places, the condition is definitely better than the previous batch, but the price is a little more expensive......"

"How much?" Jiang Ge frowned.

The boss rubbed his fingers and sneered, "It's 10 silver coins and 20 silver coins more expensive than the previous batch." ”

…………

Leaving Jiang Ge from the grocery store was a little unpleasant.

Looking at the boss's performance, he knew that 20 silver coins was definitely a loss.

However, he was not in the mood to bargain right now.

"Fortunately, the most important five-color glass has arrived......"

In Jiang Ge's hands, a glass bead in the sun, refracting colorful colors, like a dream.

The invisible art he mastered was a ritual called the Ritual of the Mirror.

He got it when he was reading a book called "The Origin of Mirrors".

The materials required for the ceremony include:

"Mirrors, laurel petals, five-colored glass"

The mirror he had already prepared.

Now the laurel petals and five-colored glaze are also in hand.

"Next, it's time to find a suitable venue for the ceremony."

Jiang Ge thought for a moment, and then went straight out of the city.

…………

Outside Ryugu Castle, an abandoned factory.

The surrounding area is barren and rarely inhabited.

Jiang Ge stepped on the knee-high grass and walked into the abandoned factory.

The roof of one part of the factory was in disrepair and decayed, and a large hole with a diameter of three or four meters was broken.

A large expanse of clear blue sky is exposed.

Jiang Ge nodded slightly, the ritual of the mirror is not very demanding on the environment, only in the celestial phenomena.

So it's just right here.

From finding an iron rod covered with rust, Jiang Ge cleaned up the open space under the big hole a little, and threw the iron rod aside.

"By the way, the beast is also a problem......"

Jiang Ge went to the periphery of the factory again, inspected it, and confirmed that there were no traces of wild beasts.

But a little bit of it was done just in case.

Then he went back to rest in the clearing.

While waiting for the night to come.
