After playing with Hiratsuka Shizu for a while, Gu Yun returned home.

"came back?"

Mother never restricted Gu Yun in anything except monster matters, such as his relationship with Shizuka Hiratsuka and his life plan.

Anyway, as long as it doesn't look like that smelly old man, she supports it.

"Mom, I'm going to rest."

"OK, good night."

Tamaki Iijima still had to work, and Nao Hayasaka accompanied her.

"Then now, let's start learning spells."

Gu Yun's return to Tokyo does not mean that the practice of magic has come to an end.

If you have a way, practicing is like sailing against the current. If you don't advance, you will retreat.

The cultivation method of fishing for three days and drying the net for two days, when it comes time to use it, it will be too late to regret it.

So Gu Yun made a plan for himself.

Be an ordinary person during the day, and take time to practice magic at night.

Fortunately, because of the existence of spiritual power, Gu Yun's physical fitness has been greatly improved, and his need for sleep has also been reduced.

Looking at it now, 5 hours of sleep is enough for Gu Yun to restore all his energy.

"Master, what spells are you going to practice today?"

Xiao Bai got into Gu Yun's arms, wagging his tail and asking curiously.

"Spiritual Vision."

"Vision?"

Xiaobai heard this spell for the first time: "What is this?"

Gu Yun's current spiritual power is not too much, probably equivalent to the level of the weakest lower-level demon.

"The so-called spiritual vision is the magic of seeing monsters and ghosts."

"Isn't that just 'hell'? This still needs practice?"

Not only Xiaobai, but also the three-tailed fox, Hannya and Zashiki Warashi are a little confused.

In other words, the ability to "see ghosts" should be similar to Gu Yun's talent.

What’s the point of practicing it?

"Xiao Bai, that's not right. The art of spiritual vision is not that simple."

In fact, Gu Yun had the same idea as Xiao Bai at the beginning. He could see monsters and ghosts. This still requires practice. Isn't that the instinct of people with spiritual power?

However, this is not the case.

"Let me explain it to you."

Gu Yun conveyed the knowledge that his grandfather told him to Xiaobai, the three-tailed fox and other shikigami: "To put it simply, in the world we live in, in addition to the multiple spaces such as the real world and the hidden world horizontally, there are also digital spaces vertically.

A different dimension.”

This dimension is not simply space, but more like the overlapping of three primary colors.

"Look."

Gu Yun took out three pieces of red, yellow and blue transparent plastic paper from the schoolbag he visited in the room.

"When yellow and blue overlap," Gu Yun turns on the light, overlaps two pieces of plastic paper and puts them under the light: "It will look like this."

"It's turning green!"

Xiaobai showed a surprised look, and the fox tail began to swing rapidly: "Why why?"

"In terms of the principle, it's a bit complicated."

Gu Yun didn't explain much. He just took the three primary colors as an example: "You just need to know that the world we live in is made up of multiple overlapping dimensions."

"Master, what you mean is that we live in multiple spaces," the three-tailed fox said, "It's just because of different states that we can only feel part of the world, right?"

"That's right."

Gu Yun nodded and said: "Sister Fox, Xiao Bai, Hannya, and Xiao Zashiki, although you are all monsters, your types are different."

The three-tailed fox and Bai Zangzhu were both trained as spirits by foxes.

Hannya and Zashiki Warashi are more like spiritual bodies that have changed into what they are now due to various reasons.

"Grandpa said that humans and monsters are in different worlds."

Gu Yun picked up the stacked yellow and blue colored papers: "Suppose that humans are green made from blue and yellow."

"Then, I'll adjust the blue part now."

Gu Yun separated the two pieces of paper and said, "We use this blue part to refer to the soul, so what is the remaining yellow part?"

All the shikigami looked at each other, and Prajna said hesitantly: "Yes, corpse?"

"right."

Gu Yun said: "The living ones are human beings. Once they die, they become corpses."

"We call living people people, but we don't call corpses people," Gu Yun said. "Perhaps ethically, we will respect it and protect it."

"But essentially, a corpse is just a piece of meat that has begun to rot, a dead object."

According to Grandpa, the world in which the human body lives is called the ‘present world’, which is what we often call the ‘human world’.

After a person dies, he or she will become a ghost, which is what Easterners call a ghost.

"Ordinary people are like standing on the first floor."

"Monsters and ghosts are located on the second floor," Gu Yun said, "so ordinary people cannot see monsters and ghosts, nor can they touch them."

Just like Hannya and Zashiki Warashi at this time, they are actually unable to directly touch human beings and things in the real world.

"Yeah, I got it."

Zashiki Warashi clapped his hands, then happily walked towards the wall, then passed through the wall, and then got his head in from the outside: "Is it like me?"

"right."

Gu Yun smiled slightly: "In this process, Xiao Zashiki, you didn't use any demonic power at all, right?"

"Um."

"As for me, certain sorcery can still be done."

The three-tailed fox said that she can use a special magic that allows her to travel through the shadows.

But this is different from Zashiki Warashi.

Zashiki and Prajna already possess this spiritual property, while the three-tailed fox and Hakuzoshu need to use demon power to travel through matter.

"So in legends, there are often stories of demon foxes and white snakes being accidentally injured by humans and then being rescued by humans."

If the three-tailed fox and Bai Zangzhu didn't use their demon power, they would still not be seen by ordinary people, but they would just not be able to see them.

Just like a three-tailed fox standing there, if someone comes running in front of it, the three-tailed fox has no intention of avoiding it.

Then the opponent will hit the three-tailed fox, as if hitting a wall of air.

"This is the power of monsters."

"Using your demonic power, youkai can adjust their own state," Gu Yun explained: "As spirit bodies, Kozashiki and Hannya, you can use your demonic power to contact others."

"As for Sister Fox and Xiaobai, you can use your demon power to prevent ordinary people from touching you."

Therefore, spiritual power, like demonic power, can also allow Gu Yun to contact other worlds through specific forms.

"But, just like the forces acting on each other."

"I can see and touch them," Gu Yun said. "In turn, they can see me and touch me."

The art of psychic vision is not as simple as most people think. It is actually a forbidden art and carries great risks.

"Then Master, after you use spiritual vision, will you disappear from our eyes?"

"Won't."

Gu Yun quickly shook his head and said, "I will not disappear."

"Spiritual vision will not make people who can see me unable to see me."

"Spiritual vision allows you to see things that you couldn't see me and things that I couldn't see."

If the dimensions are compared to a ladder, ordinary people stand on the first section, and demons and ghosts stand on the second section.

So with the spiritual power of Gu Yun and Iijima Tamaki, they actually have one foot on ordinary people and the other on demons, so that their bodies can cross two steps at the same time.

This also means that if Tan Yun and her son slap, whether it is the ghost Zashiki boy or the physical three-tailed fox, they will be hit by them.

Of course, the premise is that the two do not use magic or dodge.

"I see."

A group of shikigami suddenly realized that they were demons, but they had never studied their own nature.

In fact, this is not Grandpa Gu Yun’s research.

The art of spiritual vision was the work of a close friend of my grandfather's. That man lived in Kamakura, his name was Kotaki Goshiro, and he passed away a few years ago.

"What I have to do now is to stretch my steps so that I can take a few more steps."

Theoretically, with Gu Yun's spiritual power, he should be able to see all the world by nature.

However, this is too dangerous.

Humans are animals capable of self-protection, and so is Gu Yun.

He is still very weak, so his body instinctively resists receiving extremely dangerous information.

In the words of his grandfather, even if Gu Yun does not learn the art of spiritual vision, as his strength increases, his spiritual sense will be greatly improved.

And when that time comes, Gu Yun doesn't want to see more, but to cover his own light, so that he can see as few things as possible, and reduce the prying eyes of those high-latitude monsters.

"So, my purpose of learning psychic vision now is not to see more."

Gu Yun said: "It's just to be more peaceful in the future."

The art of spiritual vision can enhance a person's spiritual sense, and in turn, can also cover up a person's light. This is why his grandfather taught him the art of spiritual vision.

The old man wanted to protect his grandson and hide his traces.
