"OK."

Hearing that his grandfather wanted to take him to visit relatives and friends, Gu Yun was naturally willing.

He liked this supernatural world very much and wanted to visit more.

However, the old man did not take him immediately. Instead, he waited at Iijima's old house all afternoon. It was not until 11 o'clock in the evening that he called him to his side.

"Out-of-body experience?"

"Um."

Grandpa smiled and said: "Those friends of mine have been dead for many years, but they still live in Huangquan and have not embarked on the road to the afterlife."

The place Grandpa will take Gu Yun to tonight is nowhere else but the place where all living beings return after death - the other side of the Yellow Spring.

"The underworld is in another dimension, and there is no material world there."

They can use spiritual vision to enhance their existence and come into contact with the spirit of the underworld, but that is too troublesome.

The best way is to leave the body and then go to the afterlife like ordinary dead people according to the rules.

"The most difficult thing about going to Huangquan is not how to get there, but how to come back after going there."

This has nothing to do with the strength of the warlock, it mainly depends on spells and connections.

The former refers to a method similar to psychic vision, which can travel through the world, similar to drilling loopholes in the rules of the world, so as to escape opportunistically.

Network means whether you know the gods.

The status of the gods is higher than the spirits of the underworld, so they can bring some souls back to the living world.

Of course, the soul here refers to people who have not died.

The underworld has its own rules. The dead cannot come back, and the guidance of gods is of no use.

"You can't come back if you die?"

"Can't come back."

Grandpa said: "But our souls just left the body and are not considered dead. The laws of hell cannot control us."

Therefore, Gu Yun and Grandpa can go to the underworld, and then return to the human world with the help of gods or using spiritual vision.

Grandpa's spiritual vision is not advanced enough, and he cannot travel through various worlds at will like Mr. Kogoro.

However, my grandfather knew many powerful gods. In the past, before going to the underworld, he would make an appointment with them in advance or borrow some artifacts so that he could travel back and forth between life and death.

"Xiao Kong..."

Gu Yun asked: "Is it okay?"

"sure!"

Grandpa smiled and said, "With Master Tianhu, it will be much more convenient for you, Gu Yun, to travel between the two places than it is for me, Grandpa."

Friends are just friends after all, and the gods are willing to help grandpa.

They have simple personalities, and helping grandpa is like making friends with him. They wish he would come and play with them more often.

But Grandpa felt a little embarrassed for troublesome people again and again.

Conceptually speaking, grandpa is of the "no too much contact" group. He had mentioned to Gu Yun before not to go too deep into another world.

"It doesn't matter Xiaokong, she is one of our own!"

Kong Huan is different, she is Gu Yun's fox, and it is only natural to help Gu Yun travel to and from the underworld.

"We have a god in our family," Grandpa said with a smile, "It really makes people feel at ease."

"Okay, let's get started."

The grandfather and grandson came to the bedroom, where there were two quilts, one large and one small.

The two told Yaeko's mother-in-law and Iijima Juanjuan that they would rest in the same room tonight.

"Prajna, Xiaobai."

Gu Yun summoned two shikigami: "After my grandfather and I went to Huangquan, I asked you to take care of my body."

After the soul leaves the body, the body will enter a deep sleep state.

At this time, if someone with intentions discovers and destroys it, the spirit body will be judged as 'dead'.

If he happened to be in Huangquan again at that time, he would not leave.

Then, the entire underworld will directly regard you as a 'dead person'.

In other words, you can't come back.

Even with the help of gods, you can't come back.

"Leave it to us, Master."

With Prajna and Xiaobai here, and the several higher-level demon-level shikigami prepared by grandpa, no one can touch their bodies unless the big demon comes in person.

"Um."

Gu Yun lay down and then recited the mantra silently in his heart.

Not long after, a person who looked exactly like Gu Yun appeared from his body like smoke.

"Is this an out-of-body experience?"

Gu Yun glanced at himself lying down and felt very strange.

"The state of the soul is indeed very convenient."

"Why?"

When Gu Yun heard this, his eyes widened and he asked, "You, are you grandpa?"

I saw that the person standing in front of Gu Yun at this time was not an old man, but a young man wearing an old kimono.

He wears round glasses, looks handsome and gentle, just like a Japanese scholar from the previous era.

"Um?"

As the young man spoke, his body shape changed and he took on the appearance of an old man again: "Just now was my appearance when I was young. Is this the first time Gu Yun has seen me?"

"So grandpa was like this when he was young!"

Gu Yun asked: "Could it be said that in the spirit state, we can change our appearance at will?"

After saying that, Gu Yun also started to use his spiritual power, wanting to become an adult.

It's a pity that no matter what he does, Gu Yun is still the same as he is now.

"Um…"

Grandpa looked at Gu Yun's actions and laughed loudly: "Little Gu Yun, do you want to become an adult?"

"I tried it just now and it doesn't seem to work."

Gu Yun found that he could not grow bigger, which made him a little confused.

Therefore, Gu Yun looked at the old man expectantly, hoping that he would teach him how to change his age at will while in the spirit state.

"Is there a spell that can make a spirit body grow older?"

"Well, if it's a deception, it does exist."

"But really getting bigger," Grandpa shook his head and said, "I can't do it."

"its not right!"

Gu Yun just used his spiritual vision to see his grandfather's youthful state. He definitely didn't use blindness or illusion, but really made his soul become younger.

"This is the soul engraving technique."

To put it simply, it is to artificially imprint a spirit body for easy use when you grow old in the future.

In fact, many powerful female sorcerers will keep their spiritual bodies in the most youthful and beautiful state.

However, this imprinting technique is unique.

In other words, you can only freeze one form, and you can change it, but you can only engrave one form at a time, and it must be the state you are in at that time.

Gu Yun's physical body is still a child.

If he becomes a teenager in the future, he can freeze his youth form. When he gets old, he can still choose to freeze his body to keep his spirit body youthful.

But if you want to grow bigger now, it's impossible.

"Maybe there are other spells that can do this kind of thing, but grandpa really doesn't know how to do that kind of spell."

Grandpa said helplessly: "I will teach you the spell later, but given your age, Gu Yun, you probably won't be able to use this spell for the time being, right?"

"Um…"

Gu Yun said speechlessly: "In addition to being beautiful, this spell also has..."

"Ah."

Grandpa laughed softly, then changed into a young man's posture, and opened his arms for Gu Yun to observe carefully.
