Darkness is just a fixed perception of the underworld of human beings. In the fairy realm and the god realm, and even the demon realm and the netherworld, the ghosts and ghosts themselves don't think so.

In fact, before human beings came to the human world from the ghost world, they also thought that the mortal world was dark.

Just as humans believe that they will become ghosts when they die, ghosts also believe that they can only be reincarnated as humans after they die. However, immortal ghosts cannot be human, because they cannot adapt to the extreme yang and earth qi of the world and the brilliance of the sun, moon and stars.

The process of reincarnation of a ghost after death is a very natural process like a rebellious assembly line with a mold assembly line.

When entering the human world from the world of the ghost race, they have to go through a yin and yang channel, which is the way of Tai Chi pure yang, and then through the cultivation of the father's essence and mother's blood, in order to gradually dissolve their ghost eyes, ghosts and the dampness of the underworld, and then slowly cultivate the pure yang soul and flesh pills of the human body - that is, the process of becoming a child.

After ten months of offerings from the essence of heaven and earth, such as the sun, moon and stars, a pair of naked eyes that can quickly see light and things clearly in the sun can be cultivated again, and at the same time, the placenta forms a human form - that is, the fetus.

Therefore, the mortal fetus with the naked eye is actually an explanation of the ghost world when it sends farewell to the ghosts who are about to be reincarnated as human beings, and this is not invented by human beings themselves.

It is not easy for ordinary ghosts to be reincarnated as human beings, just as it is as difficult for mortals to cultivate immortals and ascend. If one accidentally misses the opportunity to be reincarnated, he can only become an ownerless lonely soul, wandering at the mouth of the Three Realms, waiting for the time tunnel of the next reincarnation to come.

However, the time tunnel of general reincarnation often takes many years to appear once, and it is very crowded and congested, so it is not easy to squeeze in.

These ownerless lonely souls wander around, once they are sucked away by the Demon Dao, they will become one of the demonic thoughts, and then after a small number of them, these demonic thoughts will merge with each other and fight to become one, becoming a lawless god-breaking demon!

If the countless Godbreaker Demons seize the opportunity to gather again, they will become existences that can kill everywhere in the Three Realms - it is for the Asura Demon Demon God.

However, no matter how powerful the demon god is, he will only live for hundreds or thousands of years, and then he will die, and his ashes will be turned into air and water.

Therefore, as long as there is such a demon god, he will cultivate his own forces and henchmen, and ask for his life from the immortals - he wants to become an immortal.

This is highly consistent with the idea that humans want to live a long life, so they are actually much more powerful than humans.

In their world, the rules of survival are even more ruthless, the living environment is also very harsh, and the competition has become very fierce.

Because after all, inside and outside the Three Realms, only immortals can live endlessly.

It is also because of this that there will be the outbreak of the war between immortals, demons, gods and demons once or twice every few thousand years.

The current netherworld may be about to go to the shadow of a war between the gods and demons of the netherworld!

Because in the world of the Netherworld and Ghost Dao, it is also the gods who do the talking.

In the entire Three Realms and beyond, only the human world and the demon realm are not the territory of the immortals, and the True Heaven Realm and the Sea and Sky Wonderful Sound Realm, and even the Netherworld are all places ruled by the gods, so when the Asura Devil attacks the Heavenly Court, he will send troops to the Ghost Clan's Underworld and the Heavenly Court at the same time.

However, they were relatively close to the Netherworld, and the time difference and spatial dimension between the two realms were similar.

At the same time, since the Shura World was under the Netherworld, if they wanted to attack the Heavenly Court, they must first take the Netherworld.

In view of this, the road from the Asura Realm to Heaven was relatively long and difficult to find, and they could only use the Netherworld. Because if the Asura Realm wants to bypass the Netherworld and go straight to Heaven, it will be too far away, millions of times farther than from the human world to Heaven! Therefore, once the two worlds of immortals and demons go to war, the war will generally start from the netherworld.

"Senior brother, you forgot to open your eyes on the earth." Seeing that I was in a daze, the Holy Spirit smiled at me and said.

"Oh! I was distracted. As I spoke, I opened my eyes on the ground.

"Senior brother, close your human eyes! Otherwise, the ghosts will eat your soul when they see it. Then the Holy Spirit reminded me.

"Thanks for the reminder! I haven't been to the underworld much, and I'm always lost. I closed my eyes in embarrassment.

"You're always like this, how can we protect you?" Tianyantong hid in my hair and whispered.

I patted my head, and he stopped talking.

This is only the entrance to the netherworld, a very desolate canyon, there is a hole at the mouth of the valley, and there are a lot of phosphorus fire street lamps in the cave all the way through, looking out of reach, very deep.

Under the street lamp, the black dragon with ink, rain and smoke and a few of their children were standing waiting for me and the Holy Spirit.

"Hurry up! What are you doing? It's so cold standing here, you can't see anyone, so you can't walk faster. Yuyan turned back and urged us.

At the end of the blue and green street lamp, there is indeed a city gate, which is not much different from the Zhonghua Gate, but it looks as if it has just been brushed with green paint from a distance, and the heavy green paint keeps flowing down from the city gate, as if it is inexhaustible.

On the city gate, there are three ghosts and ghosts, and they are incomparably bright red characters: Zhongsu Gate.

These three words are like a demon that eats people, one will become a skeleton, the other will become a child...... The wind gusted and was very terrifying.

She seems to have just learned to close human eyes, and looking at this place is like looking at Jinling City, and she thinks that she has arrived at Zhonghuamen Castle!

"Ink, look! Isn't that Zhonghua Gate? It's just a big battle, and the blood of the strong men dyed these three big characters red! These chengguan don't look for anyone to wash them. Yuyan said loudly.

"Miss, that's not Zhonghua Gate, it's Zhongsu Gate." Miao Miao corrected her and said.

"I heard that the Zhongsu Gate is the first gate for celestials to enter the ghost world, and you can't enter casually without a ghost talisman. I don't know if it's true! "I don't know where I heard the ink, it's very mysterious, and where the rain and smoke are blowing, the cowhide road.

"Did the sister-in-law in Jiming Temple tell you or did the girl on Xinjiekou Street tell you?" The black dragon grinned and began to trick my little apprentice.

"Black Dragon, don't go around him. He has become an immortal, you still give him to take it to the human knowledge! If you want to talk about it, you should talk about it well, make it clear, and just popularize the basic common sense of the fairy family in and out of the ghost world for the children. I shook my head and smiled at the black dragon.

"Pixiu, tell these junior brothers and sisters about it." The black dragon said to Pixiu seriously.

"Okay, uncle." Pixiu agreed, and carefully talked to the rain smoke and ink, as well as the little green cow and the son of heaven, about the rules of the ghost world and some methods for the immortals to enter and exit.

"Senior brothers, junior sisters, we are immortals, so to enter the underworld, you must have a true heaven and earth pass, that is, the Netherworld Ghost Talisman. Only the immortals who hold the Nether Ghost Talisman will not be captured by the great gods of the Netherworld when they enter the underworld. Only with these spirit runes can the immortals enter the underworld to be protected by the ghost king, and they can go out at any time after entering, without restrictions. Pixiu said.

"Senior brother, why don't we have a spirit rune, can't we go back?" Yuyan looked around and asked faintly.

"Our Immortal Academy admission card has activated the permission of the Three Realms to pass through, right in our minds, he will let mortals see us We are mortals, and we are ghosts when the underworld sees us, so you don't have to be careful." Miao Miao explained to Yuyan in a whisper.

"Yes! There are two portals to enter and exit the underworld from the mortal world: Yanzi Gate, which is forty-five and a half degrees northeast; Zhongsu Gate at forty-five and a half degrees to the southwest. There are also two routes from the fairy world to the underworld: the sunrise shadow in the east and the sunset shadow in the west. Xiao Qingniu also joined the discussion with a smile and said.

"Then we should be going to the rising shadow of the East today! Why did you run to the southwest forty-five and a half degrees? The Son of Heaven asked Xiao Qingniu in confusion.

"Because we can't take the immortal road to enter the underworld now, we will be discovered by the demon spirits who attacked the underworld!" Xiao Qingniu said quietly.

"It's not that I'm afraid that a few of you will be scared, that's why Mr. wants to start with humanity!" The Holy Spirit said.

"Don't worry, everyone, wait for me to speak slowly. Cough! Cough! Cough! Pixiu followed the example of the black dragon and shouted.

"That's right. There are still some differences between the underworld and the netherworld! Everyone will know all the way. The ten kings of the underworld are in charge of the ghosts and spirits of mortal flesh and mortal wombs, that is, the souls of the dead. The human body is dead, but their consciousness and soul are not dead! This is a cyclical regeneration process of soul reincarnation, becoming a human and a ghost, and this process is very complicated, and it will not be explained clearly for a while. I'll tell you about the underworld and the underworld.

What we are entering now is the underworld. One hundred and eight thousand miles below the underworld, that is the vast netherworld, and that is where we will finally reach. In some dark corners of the netherworld, there are scattered large and small Asura Demon Realms, and this is the approximate path to enter and exit the Human Ghost Realm Shura Realm. Pixiu said seriously.

"Then why is this city gate built like the Zhonghua Gate Castle! Even the three words are pretty much the same. Yuyan said faintly.

Knowing that this was the first gate of the underworld, she was still a little scared, and her body couldn't help but lean towards the ink very honestly.

Shui Mo looked at the look of horror in her eyes, and gently grabbed her hand and held it tightly.

Yuyan glanced at the ink with a calm look, and her mood slowly calmed down.

"This is because the underworld is very close to the human world, and their path of life and death is constantly circulating in the two worlds of yin and yang, so in order to find each other's realms in an unconscious state, their territories are roughly equal." Pixiu said.

"Oh! That's good! When I go to the underworld as I am in the mortal world, I will not be afraid. Yuyan leaned her head on Ink's shoulder and laughed.

"Not exactly. The human and heavenly realms are colorful, while the ghost realm is a single-color world, and there are only two colors, and everyone will know it all the way. Pixiu said with a smile.

He said this because most of us had never been to the ghost world.

"Hey! I talked about it for a long time, but I didn't understand anything. Old? When they arrive, let's go. The black dragon interrupted Pixiu's introduction and took the lead and walked towards the Zhongsu Gate.

"Heaven and earth are endless, and there is clarity everywhere! From the underworld to the human world, and the immortals, this is the continuous evolution and transformation process from a low-level civilization to a high-level civilization, which is very complicated. In the future, everyone will slowly realize. The black dragon kept saying as he walked towards the Zhongsu Gate.

"Isn't it okay to say that: the demon path is close to the ghost race, the ghost race is close to the human race, and the human race can only be close to the immortals?" Ink asked the black dragon puzzled.

"Your understanding is still very naïve, but it is very close to the truth. If the boundaries are flat, then this understanding is understandable. However, all walks of life are made up of large and small spherical objects, so they cannot be treated so hastily. The black dragon said with a smile.

"Ink, only the underworld, the human world, and the immortal world have a height, because these three worlds are all within the sphere of influence of the Lingxiao Palace. In addition to the Three Realms, there are many nameless worlds, their existence is multi-dimensional eight-dimensional and even ten-dimensional space, such as the Asura Realm, the Heavenless Realm, the Infernal Realm, etc., the creatures of these worlds are non-human, non-god, non-immortal, non-ghost creatures, I usually call it the Demon Realm! That is, the world of black hollows. People and immortals generally can't enter that world, and the ghost world is closer to which world. The Holy Spirit said to them.

"Huh! Ink, look, the three words 'Zhonghua Gate' are dripping blood! Yuyan buried his head in Ink's arms and said quietly.

"Where! You're dazzled. It's freshly painted, and it's still emitting dark green smoke! Don't be afraid, it could be because it's steaming underground. Shui Mo pulled Yuyan and comforted her as she walked.

"There are a thousand Hamlets in the eyes of a thousand people, but there are only two or three shades of the ghost world in the eyes of ten thousand people: red, blue, and green. The red is the food, the blue is the light, and the green is their blood. Pixiu deliberately said loudly to Miao Miao.

The implication is to tell ink and rain and smoke not to be afraid.

"It's not that complicated! There is no color difference in the ghost eye, and it can only distinguish simple red, black and green, blue is the common color of hope from all walks of life, because the fairy world is blue and transparent, so the lights inside and outside the Three Realms are all one color, which is blue. It represents hope. The black dragon said with a smile.

As we spoke, we had already walked to the gate of the ghost world.

The three big characters of Zhongsumen are like a group of red imps, who are trying to drag and carry a Fang Tian painting halberd, which is very funny and ridiculous, but secretly reveals a strange majesty, which makes people secretly marvel at it, dare not approach easily, and dare not speak loudly casually.
