Tokyo: My Hundred Demon Scroll

"Gu Yun's grandfather actually studied martial arts?"

Hiratsuka Shizuka's eyes sparkled: "Sugawari!!"

Gu Yun: Aren't you even a little bit suspicious?!

"May I become his apprentice?"

"Please, Gu Yun, next time you go back to the countryside, could you take me with you?"

Looking at the excited Hiratsuka Shizuka, Gu Yun silently apologized to his grandfather in his heart: I'm sorry, old man.

"Is this the master's friend?"

Unbeknownst to them, next to the Hiratsuka family's dojo, Hannya, Shiro, and the three-tailed fox were watching the two playfully fighting.

Prajna's eyes were full of envy; he also really wanted to play with Gu Yun.

Chapter 18 Psychic Vision

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

"came back?"

Aside from matters involving yokai, his mother never restricted Gu Yun in any way, such as his relationship with Hiratsuka Shizuka or his life plans.

In short, as long as it's not like that stinky old man, she'll support it.

"Mother, I'm going to rest."

"OK, good night."

Tamaki Iijima still had to work, so Nao Hayasaka stayed with her.

"Now, let's begin learning magic."

Gu Yun's return to Tokyo did not mean that his training in magic had come to an end.

As the saying goes, spiritual practice is like rowing against the current; if you don't advance, you'll fall behind.

A half-hearted approach to self-cultivation will leave you with nothing but regret when the time comes to actually use it.

Therefore, Gu Yun set a plan for herself.

He lives like an ordinary person during the day, but at night he sets aside time to practice magic.

Fortunately, due to the presence of spiritual energy, Gu Yun's physical condition has greatly improved, and his need for sleep has also decreased.

As things stand, five hours of sleep should be enough for Gu Yun to fully recover her energy.

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

Little White snuggled into Gu Yun's arms, wagging its tail and asking curiously.

"Spiritual vision."

"Spiritual vision?"

When Xiaobai first heard about this spell, he asked, "What is this?"

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

"So-called spiritual vision is the magic that allows one to see demons and monsters."

"Isn't that just 'seeing ghosts'? You need to practice that?"

Not only Shiro, but even the Three-Tailed Fox, Hannya, and Zashiki-warashi were somewhat confused.

The ability to 'see ghosts' is probably similar to Gu Yun's talent.

What is the point of practicing it?

"Little White, something's not right. The art of spiritual vision isn't that simple."

In fact, at first, Gu Yun thought the same as Xiao Bai: to see demons and monsters, that requires cultivation, isn't that just the instinct of people with spiritual power?

However, this is not the case.

"Let me explain it to you."

Gu Yun conveyed the knowledge his grandfather had taught him to Xiao Bai and the Three-Tailed Fox, among other shikigami: "Simply put, in addition to the horizontal multiple spaces such as the present world and the hidden world, there are also several different dimensions in the vertical dimension of our world."

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

"Look."

Gu Yun took out three transparent plastic sheets—red, yellow, and blue—from the backpack inside the room.

“When yellow and blue overlap,” Gu Yun turned on the light, placed two pieces of plastic sheeting together under the light, and said, “it will look like this.”

"It's turned green!"

Little White looked surprised, and its fox tail began to swing rapidly: "Why? Why?"

"The underlying principle is somewhat complicated."

Gu Yun didn't explain further; he was just using the three primary colors as an example: "You just need to know that the world we live in is made up of multiple dimensions overlapping and merging together."

“Master, do you mean that we live in multiple dimensions,” the three-tailed fox said, “but because of different states, we can only perceive parts of the world, is that right?”

"Yes."

Gu Yun nodded and said, "Sister Fox, Little White, Hannya, and Little Zashiki, although you are all yokai, you are not the same kind."

Both the Three-Tailed Fox and Hakuzosu are fox spirits who have cultivated themselves into human form.

The Hannya and Zashiki-warashi are more like spirits who, for various reasons, have transformed into their current forms.

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

Gu Yun picked up the stack of yellow and blue colored papers: "Let's assume that humans are green, which is the result of blue and yellow."

"Now, I will extract the blue part."

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

The shikigami exchanged glances, and Hannya hesitated before saying, "Yes, a corpse?"

"right."

Gu Yun said, "A living person is a human being; once dead, they become a corpse."

“We call living people people, but we don’t call corpses people,” Gu Yun said. “Perhaps ethically, we would respect it and protect it.”

"In essence, a corpse is just a piece of flesh that has begun to rot; it is a dead thing."

According to my grandfather, the world in which the human body exists is called the 'present world,' which is what we often call the 'human world.'

After a person dies, they become a ghost, what Easterners call a spirit.

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

“The monsters and ghosts are located on the second level,” Gu Yun said, “so ordinary people cannot see or touch them.”

Just like Hannya and Zashiki-warashi at this moment, they are actually unable to directly touch humans or things in the real world.

"Yeah, I got it."

The Zashiki-warashi clapped its hands, then happily walked towards the wall, passed through it, and poked its head in from the outside: "Is it like me?"

"Correct."

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

"Ah."

"As for me, I can still do certain sorcery."

The three-tailed fox stated that she could use a special kind of magic that allowed her to move through shadows.

But this is different from a Zashiki-warashi.

Zashiki and Hannya possess these spiritual characteristics by themselves, while the three-tailed fox and Hakuzosu need to use demonic power to travel through matter.

"Therefore, in legends, there are often stories of fox spirits and white snakes being accidentally injured by humans, and then being rescued by them."

If the three-tailed fox and Hakuzosu do not use their demonic powers, they will still not be seen by ordinary people, but that's all they will be—they will simply be invisible.

It's like a three-tailed fox standing there, and if someone runs towards it, the three-tailed fox doesn't intend to avoid them.

Then the opponent will crash into the three-tailed fox, as if hitting an invisible wall.

"This is the demonic power of a monster."

“By using demonic power, demons can regulate their own state,” Gu Yun explained. “As spirits, Kozashiki and Hannya, you can use demonic power to contact others.”

"As for Sister Fox and Little White, you can use your demonic power to make yourself untouchable by ordinary people."

Therefore, spiritual power, like demonic power, can also allow Gu Yun to come into contact with other worlds through specific means.

"However, just as forces are reciprocal."

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

The ability to see through things is not as simple as most people imagine; it is actually a forbidden technique with extremely high risks.

"Master, after you use your spiritual vision technique, will you disappear from our sight?"

"will not."

Gu Yun quickly shook her head and said, "I won't disappear."

"The ability to see through vision will not prevent those who could see me from seeing me."

"Spiritual vision is the ability to see things that I couldn't see before, and things that I couldn't see before."

If we compare dimensions to stairs, ordinary people stand on the first step, while demons and ghosts stand on the second step.

So, those with spiritual power like Gu Yun and Iijima Tamaki essentially have one foot on an ordinary person and the other on a demon, allowing their bodies to straddle two steps simultaneously.

This also means that if Gu Yun and her son slap someone, whether it's a ghostly Zashiki-warashi or a three-tailed fox with a physical body, they will be hit.

Of course, this is on the premise that neither of them uses sorcery or dodges.

"I see."

The shikigami suddenly realized that, as demons, they had never studied their own true nature.
