The teacher and apprentice are on the rise!

Gui Zangzong's collection of books is vast, and it is impossible to guarantee that he really knows what secrets.

Xue Yu didn't care about her nonsense, and looked at Tian Xingzi vigilantly: "What do you mean, what happened to the demons?"

The latter didn't answer him, just smiled charmingly, and suddenly stroked his abdomen exposed outside the tight clothes with one hand, and rested his other forearm on his chest, and gently picked Xue Yu's cheeks when his cheeks were flushed. Said: "My sister is really willing to be for my brother..."

After finishing speaking, his shining eyes glanced at Xue Yu's lower abdomen again.

That gaze seemed to be looking at a piece of fat and thin pork belly, and Xue Yu's hairs stood on end under her stare.

Di Zhao frowned and looked at her: "Don't play charades, what do you know?"

Tian Xingzi sighed in a dignified manner: "It's done, it's useless to say more now."

Di Zhao wanted to ask again, but saw that Tian Xingzi's expression was slightly restrained: "I didn't say it before, because it's not very useful to us, it's just some romantic anecdotes."

She glanced at Xue Yu, and said lightly: "I'm afraid that my brother is thin-skinned, and he will be ashamed all the way after hearing it."

Xue Yu: "Then stop talking."

So Tian Xingzi laughed again.

Di Zhao didn't speak again, but he didn't know what he was thinking, his face turned blue and pale.

She took a breath and looked at Xue Yu, as if she wanted to say something, but finally held back.

"Let's go."

After the episode, everyone continued along the road.

There is almost no need to deliberately identify the direction, they only need to keep walking in the direction of the distant beam of light.

The underground palace is tightly wrapped by rock walls, with a roof and a cover, like a big urn.

It stands to reason that the echo of such an environment must be very loud, but several people deliberately did not make a sound, and the surroundings were really quiet, as if the tens of thousands of demons living in this underground palace were all dead.

The turbid air became thicker as it went in, and the green light of the ground fireflies became denser, and there were gradually scattered traces of houses in front of it.

The people living outside the central circle seem to be ordinary demons. Presumably, the whole family moved here under the leadership of that powerful demon.

There is a house tens of feet away, which is some distance away from other houses, and only one magic cultivator lives in it.

The demon cultivators were much lower than the others, so they definitely couldn't tell whether their meridians were going forward or backward, but since they had real demon cultivators, it would be more convenient for Xue Yu to explore the way than others.

Everyone turned off the lights in their hands, and watched Xue Yu walk towards the house from the sidelines.

The house was completely built of stones, and even the roof was covered with a huge thin stone. The surface of the stone was densely covered with ground moss, and the faint light outlined the square stone house.

The door only has an opening, which is blocked with a big stone in the house.

Xue Yu scanned with his divine sense, and the demons inside were sitting cross-legged on the stone bed, probably cultivating.

A sense of strangeness emerged out of thin air. For some reason, he always felt that something was wrong.

Xue Yu scanned for a long time but couldn't find any feeling, so he simply stopped thinking about it and concentrated on looking at the demons inside.

It was a male demon, wearing ordinary coarse cloth clothes, he was surprisingly thin as if he hadn't eaten enough, and there was no flesh on his body.His appearance is the same as that of Renxiu, but because he has been living underground, his skin is sickly pale.

Xue Yu looked at himself, and felt that he could not tell whether he was white or not with his naked eyes, so he would not reveal his secrets.

There is a certain tribal totem-like pattern tattooed on the neck of the other party. Maybe the luminous plant juice such as firefly moss was added to the dye, and it still glows faintly in the dark. choker.

Xue Yu thought for a while, and got a tattoo on his neck with the same trick as his, and then went straight to call for the door.

He knocked on the stone and deliberately didn't speak, thinking that if he couldn't understand the language, he would pretend to be dumb, but he heard the demon inside ask: "Who is it?"

Xue Yufang said softly: "I want to beg for a drink."

The stone door in front of him was moved away, revealing a skinny and vicissitudes of life face.

The demon cultivator froze for a moment when he saw Xue Yu: "You are—"

Before the other party finished speaking, his eyes shifted to his neck and became vigilant: "Why is your number the same as mine?"

Xue Yu just wanted to exhale some fresh air to prove that he was also a demon like him, but he was stunned when he heard him say that.

serial number?what number?Something like an ID number?

How could this magic cultivator tell what number he was at a glance?

The other party's gaze was so obvious that Xue Yu recognized that he was looking at his neck almost instantly.

What's on his neck?

It's that totem pattern!

Xue Yu looked at the demon's neck suddenly, and his back was covered in cold sweat.

Only now did he realize, what kind of totem pattern is this?It's a string of slender numbers squeezed together!

The numbers were written with twists and turns in an extremely artistic manner. Although they were still written in the world of cultivating immortals, they couldn't be read at a glance.

How could someone print their ID number on their necks!

Xue Yu raised his hand to directly restrain the man, and signaled to his distant partners to come over.

The intricate patterns on the surrounding stone walls disappeared in a flash, Tantai Jue gave everyone a wink, indicating that the formation in the room has been set up, and they can do whatever they want.

"He recognized it just by meeting him." Xue Yu pointed to the pattern on Moxiu's neck annoyedly, "Each of them should have a number like this on their necks, but I didn't recognize it at first, and they changed into identical ones. .”

Wu Hongyan snickered at the side: "I said before that we should just grab one."

Di Zhao said: "The ordinary demons on the edge should not know anything, and there is no need to entangle with them."

After all, she sent a message to Lingbi, telling the other teams about the number tattooed on the neck of the Mozu.

Naturally, the other teams didn't have half-demons who could act as undercover agents. They all focused on lurking and observing. They didn't go up to deceive people like them, so they didn't expose their whereabouts in front of the other demon cultivators.

After reading Di Zhao's warning, the other companions in Lingbi were quite surprised: number?The demons also numbered each clansman?

At first, Di Zhao regretted that he agreed to this plan of pretending to be a demon in a daze, but having such a harvest can hardly be regarded as a pleasant surprise.

With a gentle expression on her face, she comforted the demon cultivator and said, "Don't be afraid, we just entered by accident from the outside and saw that there are people living here, so we came forward to inquire because we were very curious."

The demon clan was confused: "Where is the outside?"

Zhan Ling interrupted: "It's just outside the stone wall."

"Beyond the stone wall?" The other party was stunned, as if he still didn't understand what Zhan Ling meant.

He couldn't see the cultivation of the people in front of him, he only looked at those white necks, and saw Xue Yu who had black lines covering his neck just now. At this time, the lines disappeared. Shrinking his neck, he said cautiously: "But you come from the inner city, and you are an adult who works in school?"

Everyone was silent for a moment.

Xue Yu stopped Di Zhao who was about to say something, smiled and climbed up the pole: "Yes, that's right, that's it."

Gan Bingmu—that is, the poor demon who was unlucky and blocked the door before, saw that there was a big man visiting his home, so he went out excitedly with a net bag and came back with a bagful of firefly moss.

The pocket of luminous moss that has not yet withered is like a small light bulb, illuminating the entire stone house for several degrees.

This small stone house is barely the size of an ordinary bedroom, and the furniture is the same as prehistoric stone platforms and stone beds.

If it weren't for the fact that the house is really barren, I'm afraid it would still look very cramped if all seven of them entered the house.

In contrast, Gan Bingmu also specially picked a bundle of Tendrica moss for lighting, which obviously paid great attention to them.

Xue Yu let his companions do whatever they wanted, while he himself watched the other party rushing about with an unfathomable expression, as if the emperor was making a private visit in disguise.

Well frogs can't talk about the sea, summer insects can't talk about ice, their worries about exposing themselves as human cultivators are unnecessary.

If you tell the demons that you are from outside the stone wall, it is like a group of people suddenly returning to the dynasty that still had a "round sky" in their cognition of the universe and saying that they are aliens.

The ancients would not sneer and say that you have lied to me or that you are sick, but they simply do not understand what you mean.

When Confucius met a grasshopper, he would say that there are three seasons in a year. Xue Yu guessed based on their previous conversations that most of the demons are like the grasshopper that grows in spring and grows old in autumn. Maybe they are born in this prison. In the novel, they think that the world has boundaries, and there is no concept of "beyond the stone wall" at all.But intelligent beings are still different from plants and insects after all. Gan Bingmu doesn't know that he is living in a cage. Anyone who knows can tell him that the powerful demon clan who used himself as a container back then knew that he was living in a cage. They escaped from the vast ground into the ground.

But Gan Bingmu did not receive this kind of education—or, the "ruler" here—if he had any, he deliberately made these ordinary demons so ignorant.

Why?Xue Yu was a little confused.Is it just to make these demons stay underground willingly?

In the light of the gathered ground fireflies, everyone asked Gan Bingmu what the so-called number on their necks meant by the name of the so-called test.

Gan Bingmu replied, saying that the first few digits of the number represent his village, and the middle digits represent the birth order of the people in the village.

The latter two are more special, representing the aptitude of the person's parents.

"Qualification?"

Xue Yu can still understand the serial number in front, isn't it just the ID number, but the qualification?Why is the qualification written on the ID number?

It's like putting everyone's high school and college entrance examination results into their ID cards, how can the scumbags live!

Gan Bingmu said honestly as if he was reciting a text to the teacher: "Mother is in front of father and father is in back. Sort from one to nine from low to high. One is the worst and nine is the best."

"Then your parents' qualifications are not very good!" Wu Hongyanhu interjected.

Xue Yu took advantage of the situation and looked at Gan Bingmu's neck.

Huh, isn't it?The two "twos" glow faintly at the end.

"Yes..." Otherwise, he wouldn't have been living on the edge of the city.

Gan Bingmu blushed and puffed out his chest secretly: "But I haven't given the gift yet, maybe... maybe my aptitude is particularly good."

Xue Yu continued to ask in a tone of "let me test you" very habitually: "What is the gift?"

"Giving the gift is to be led by the ceremonial officials to the sacrificial hall for one night, and then you will know your qualifications." Gan Bingmu replied loudly, "If my qualifications are particularly good, I can move to Zhongcheng!"

After all, he also added that personal qualifications will be added to the number after the ceremony.

And because the number will become longer and longer, in order to avoid confusion, the number representing personal qualifications will also be tattooed in red to distinguish them.

Xue Yu's expression immediately became indescribable.

This is the real way to add the test scores to the ID number!

Horror!

Xue Yu was still feeling grateful for the noble hand of the Education Bureau, only to hear Di Zhao asked abruptly: "What were you doing in the sacrificial hall that night?"

Gan Bingmu got stuck, blushed and couldn't answer for a long time.

"Oh, it's okay if you don't know, after all you haven't been there yet." Xue Yu blushed lovingly, and said persuasively, "Then do you know when you will go to give the gift?"

"It's all arranged by the ceremonial officials..." Gan Bingmu murmured like a mosquito, plucking up the courage to look at Xue Yu, "If my lord sees that I have worked well, can I tell the ceremonial officials Let me just say..."

Xue Yu said nonsense: "It must be."

The partners exchanged glances with each other, it seems that Gan Bingmu, as a demon in the outer city, is just like a slave in a feudal dynasty, even how to live is arranged by the big shots.

The world of cultivating immortals does not have such a complete household registration system. Others may not understand the "ID card number" of the demons, but Xue Yu knows that this is the control and rule of ordinary demons by the so-called big men.

Every demon clan is registered, which means that the life of the black household is difficult, and it is difficult for outsiders to mix in.

However, in modern society, ID numbers are not printed on people's necks, and the numbers are engraved on the skin like a stamp, only the livestock on the farm.

That very wrong feeling came again.

Before, Xue Yu just thought that the demons were forced to move underground, and being unknown in history was just a kind of hero buried.

However, there are various signs that the underground is not a peach blossom garden, and those demons do not seem to be living leisurely and happily without Renxiu's killing.

The demon clan powerhouse kept his tribe underground, like raising a group of pigs waiting to be slaughtered.

What is special about the demons?

Only aura.

The relationship between demons and other creatures in the world is like plants and other creatures in modern society.

Plants absorb carbon dioxide to produce oxygen necessary for living things, and demons absorb turbid air to produce aura necessary for living things.

It's just that the monks will not suffer from "oxygen poisoning" when the oxygen concentration is too high like the creatures on the earth, so the monks can practice with all their heart on the ground with only rich aura.

Someone gathered the demons in an urn and used it as an "oxygen tank" for the monks.

Looking at the ignorant Gan Bingmu in front of him, Xue Yu only felt a chill in his heart.

Did the action of Qingshi really seek happiness for the creatures in the world?Cen Shuling's mansion has been entrenched in the hostility for thousands of years, is there also the cry of the demons?

Xue Yu took a deep breath to calm down, and said in the tone of a teacher spot-checking the endorsement: "Let me see—"

"Show me your work."
