In the vast world, there are real immortals underground.

Inherited for thousands of years, there are caves in the city.

Master and the four of them stood outside this huge glass-like transparent dome, the people who came out of the three dungeons did not feel shocked, the only one who felt incredible was Master, Master He looked up at this incomparably brilliant and modern city, his heart was now truly excited, and the level of science and technology here made Master, a person in cultivation, feel incredible.

The three of them did not rush to urge my master to move forward, but accompanied him, waiting for my master to wake up from that shocked state, not for a long time, the master breathed a long sigh of relief, muttered in his mouth, and said: "I didn't expect that the dungeon here is really as rumored, it is really better to be famous than to meet, and it is better to meet than to be famous, to be able to see this scene with my own eyes is also my creation, and the feeling of being in the scene is different." ”

After listening to my master's words, Xin laughed out loud and said: "Actually, it's nothing, your human beings on the ground have experienced many major natural disasters and wars, and many civilizations have come to naught, but this is not the case with our dungeon, our civilization and race have been able to develop and continue for thousands of years, so the technological level of our dungeon is unimaginable for humans on the ground." As he spoke, the four of us walked towards the entrance to the city.

In the process of walking towards the entrance, Master made a special observation of the situation here, when they passed through a small canyon-like terrain, on both sides of the canyon, Master saw many extinct animals and plants on the surface of the earth, such as dinosaurs, and mammoths, these animals that had not existed for tens of thousands of years ago still lived well here, Master saw that most of the dinosaurs here were not like those drawn in some textbooks. It feels like modern people have put together the bones of different dinosaurs, and then, taking it for granted, dinosaurs are like that, remembering that the humans on the ground are really ridiculous and pitiful, and the spliced dinosaurs look a bit nondescript.

My master found that in the space of this dungeon, there is also a sky, but the sky does not look like the sky of the earthly world is blue, the sky here seems to be illuminated by a warm light, it looks a little yellow, and it feels more like a sunset color to Master, but it is much more comfortable than the sunset shining on people.

Master and they continued to move forward, and finally the four of them came to the entrance of the dungeon, the entrance did not see anyone guarding, but this entrance is very peculiar and strange, that is, on both sides of the two tall stone pillars, the diameter of the stone pillars seems to be at least one meter, at the very top of the stone pillar is inlaid with a red gem, this gem exudes a soft halo, it does not look dazzling, but from the inside to the outside seems to have a radioactive light, shining on the body of everyone we arrived at the entrance, This feels like a device that scans identity information.

At this time, Xin, who was standing on the side, spoke to my master and said, "Brother Dao, this is the entrance to our dungeon, and the stone pillars on both sides are the magic circles we set up at the entrance, but don't worry, the light just now is scanning the identity information of each of us, if someone wants to force their way through, they will be attacked mercilessly, and they will also call the city to the police." The light just now also has a special effect, if the person who enters the dungeon is our friend, the light will play a role in purifying the body, shining on the body of an ordinary person, will make him heal some diseases. Master nodded in amazement as he listened to Xin's introduction, and soon Xin, my master, and the four of them passed through the scanning of the entrance.

Master, after scanning the stone pillars, behind them, is the real entrance of the dungeon, and at the entrance is a square light curtain, which looks brilliant, giving people a very sci-fi visual impact.

When Master and the four of them entered the formation light curtain, what appeared in front of them was a long corridor, and on both sides of the corridor hung an unknown crystal stone, which emitted a soft but not dazzling light, illuminating the passage of the entire corridor. Moreover, the master also smelled a faint fragrance in the air, and the master asked Xin beside him to know that this aroma was a medicine used to purify the dirt on the body of people who entered the underground city, which was specially set up to ensure that the environment in the underground city was relatively pure.

This corridor is very long, Master and their group walked through the corridor for more than twenty minutes, when they passed through a square light curtain again, what appeared in front of their eyes was the real entrance of the huge glass dome, this entrance was also shrouded by a kind of light curtain, Xin made a gesture to my master, Master glanced at this light curtain, without the slightest hesitation, raised his legs and stepped in.

As soon as Master's feet stepped inside, a magical scene happened, the appearance of the city that I saw from the entrance just now, when I entered, it changed, and it was completely different from what I saw from the outside, Master saw an incomparably modern city, there were often all kinds of strange flying machines flying in the sky, and they kept shuttling at different heights and different locations above the city, and the buildings in this city were scattered, and some of the buildings themselves exuded light. Master knew that it was definitely not the kind of thing that was used to use electricity on the ground to shine, and the height of some of the tall buildings in those high-rise buildings was simply incredible, and Master found that some of the high-rise buildings were actually more than 2,000 meters high, or more than 600 floors.

At this time, the master asked with some curiosity, "Brother Xin, is this an independent space?" It's not the same scene as what I just saw outside, it's really amazing. "Hahaha, this can be said to be another method of blinding, this is mainly to confuse the eyes of some cultivators on your earth, there are many powerful cultivators on your earth, you can see the appearance of the dungeon with the eye of heaven, in order to deceive the real situation here, therefore, we have adopted a combination of higher technology and formation to conceal the truth." Xin explained to the master, and the master showed a sudden realization.

What my master originally thought was that when he was meditating, he had already seen the situation in the dungeon clearly, and he had explored it countless times with the eye of heaven, and he didn't have any new feelings about the dungeon here, but after this immersion, he found that the scene he saw on the ground before was all an illusion, and he didn't expect that the real situation was completely different from what he saw.

When Master and the others entered, there were already several people dressed in white costumes that looked a bit like those of ancient China, standing at the entrance and waiting, each of them standing on top of a platform-shaped flying machine, with only a handrail that looked simple and couldn't be simpler.

I heard one of the people in white clothes come out and respectfully said to Xin, "Elder Xin, you have worked your trip this time, and now the elders are waiting for your arrival in the council hall and sent us to pick you up." Xin nodded when he heard this, so he beckoned Master and the four of them to get on the aircraft of the white-clothed messenger.

Master is also a little curious, the function of this flying machine, when my master stood on the flying machine piloted by a white-clothed envoy, the flying machine itself emitted a soft halo, wrapping the white-clothed envoy and the master in it, and the flying machines that Xin and the others were riding on were also the same as my master's situation, they were all shrouded in a halo.

Soon the aircraft started silently, it left the ground more than a meter high, and drove quickly towards the center of the city, but the people in the halo could not feel the wind at all, so the aircraft was flying forward rapidly.

Taking advantage of the time of the flight, Master talked to the white-clothed envoy beside him, and the white-clothed envoy briefly introduced the dungeon to my master. It turns out that this underground world is more than 220 kilometers straight down from the surface, that is, it has reached the center of the earth's space. The magma is within 200 kilometers, and it can also be said that outside the center of the earth, this center is a hollow space.

The humans in the center of the earth are not as belligerent and aggressive as the humans on the earth, and there is no war in the center of the earth. The countries here do not exist in the form of states, they are divided by regions, and they are divided by regions to facilitate management and coordination, and the system is a system of elders.

Master found that most of the people here were yellow-skinned like the Chinese, and it was known that the population of the city was about two billion. The total population of the entire Inner World is about 10 billion, which is more than the total population of the earth, which is about 7 billion people. The language spoken by the people of the center of the earth is similar to that of the people on the surface, and there are languages similar to Chinese and English.

The Master and the white-clothed messenger chatted as they observed the various buildings around them and the various types of flying machines that flew back and forth between them.

These aircraft are like those seen in science fiction movies and television, floating in the air with a kind of maglev similar to maglev, and most of the maglev cars are unmanned, most of the passengers are sitting in the back, and there are maglev trains in the air of this city shuttling in the air from time to time, and my master is a little dazzled to watch.

Although the city is modern, it is also a tree-lined city, all kinds of vegetation that has not been seen on the ground are planted in different corners of the city, and the whole city is covered with a large number of greenery.

It didn't take long for Master and his group to stop in front of the tallest building in the city, and my Master stepped off the flying machine, and now he can observe this building more closely, standing under this building, and really understand what it means to be towering into the clouds, the tallest building on the surface of the earth is six or seven hundred meters, but this high-rise building has more than 2,000 meters, and the above-ground human beings have completely lost to the underground human beings in terms of architecture.

Before Master and his party reached the gate of this tall building, the crowd of people who had already stood to greet them on the high steps here were separated from low to high on both sides of the steps, and inside them were a group of men and women of different colors, all dressed in dark blue clothes with quiet and peaceful faces.

After Xin and my master got down from their respective aircraft, the white-clothed envoys on the four aircraft saluted the master and the four of them, and then drove the aircraft to leave.

Master saw more than 20 people walking down from the top of the steps, dressed in different colors, and one of them, a middle-aged man in black and white who walked at the front, caught Master's attention.

I saw that the person who came was nearly two meters tall, with yellow skin, sword eyebrows, a high nose bridge, a shaved head, a slightly upturned mouth, a strand of long hair of three centimeters on the chin, and a deep scar at the corner of the left eye, which added a bit of majestic temperament to this person.

He led a group of people, walked quickly to my master's side, raised his right hand into a fist, placed the flat end on his chest, and bowed slightly and said: "Welcome to Master Jueming, the envoy of the Above-Earth Cultivation Alliance, I am the great elder of this underground city elder's name is Jie Xiu, and I am leading all the members of our elders' council to welcome your arrival!" As he spoke, he bowed slightly to my master again, and all the elders standing behind Jie Xiu also bowed to my master like Elder Jie Xiu.

When the master saw this, he hurriedly folded his hands and bowed to the crowd who came to greet him, and said, "Elder Jiexiu is serious, and I am flattered to bother you to come to greet you." Hearing this, Jie Xiu laughed out loud, took my master's hand and walked towards the building.

Great Elder Jie Xiu nodded to Xin beside him as he walked and said, "Elder Xin, you have worked hard this time, the Elders Council has already given you a lot of credit, and I will give you a few days off to rest when I go back." "Thank you Great Elder, it's nothing, it's all what I should do" Xin sincerely excused himself, and at this time, some other elders next to him also expressed their blessings to him, everyone looked like a family and was very harmonious, and the master who watched this scene was also deeply touched, it seems that the human mentality of this dungeon is very warm.

Through the process of holding hands with Elder Jie Xiu, my master also had a general understanding of Elder Jie Xiu's cultivation, and his master's realm was between the two and the middle, and they both reached the realm of the Five Qi Dynasty.

People crowded around my master, a cultivator from the underworld, and walked towards the building, and the master walked with firm steps, and his mood was very excited and apprehensive, because the purpose of this trip was to understand the attitude of the people in the underworld towards the two alliances, and to see if it was possible to cooperate.

People have entered the interior of the building one after another, Master looked up and found that the walls inside the building are carved with the history of the development of human beings in different periods, the depiction is vivid, the first floor is a circular hall, with a radius of nearly 1,000 square meters, at the top of this hall is a crystal ball that radiates white light, it illuminates the whole hall as bright as day, on both sides of the hall there are ring-shaped marble stairs leading to the second floor, the height of the entire hall, my master visually found that there are more than 100 meters, At this time, Grand Elder Jiexiu led my master up the stairs on the left to the second floor.

When my master entered the second floor, he was even more stunned by the scenery in front of him, this second floor is also a huge circular space, the radius is at least close to 1,000 square meters, which is smaller than the hall on the first floor below, but the roof height of this second floor is indeed nearly 200 meters high, in some spaces on the second floor there are several suspended crystal balls radiating white light, the walls are carved with some symbols, and there are some runes that even the master can't understand.

In the center of the hall on the second floor, there was a huge oval-shaped white table, and my master and the elders sat down according to their respective positions, while my master sat opposite the elder Jiexiu.

When everyone sat down, the first to speak was Elder Jiexiu, and he said: "Master Jueming, let's go straight to the point, Qin Ming, the messenger sent by our dungeon, once made an agreement with the elder of your alliance, Xiao Shi, in Huashan, that he should convey the meaning of our dungeon humans to you, our existence has been to protect our earth from the very beginning, and we have been protecting, we have been fighting against some alien dark forces, I think you should also be very clear." "Master listened to Elder Jiexiu's words and nodded from time to time, because Master knew that the history of the existence of this underground human race can be a long history of human beings on the ground, and I don't know how long it has been, and my master also knows that what Elder Jiexiu said is all true.

Grand Elder Jie Xiu nodded as Master listened to him, so he continued: "Our underground human beings love peace, although we are in different regions and have different regional cultures, but we are a whole, there has never been a dispute, we have never hesitated or compromised in the face of major events, we also understand and cherish this planet more, and do not have so many greedy natures of human beings on the ground, so it has contributed to this historic dialogue between our underground and your above-ground cultivation alliance. "My master heard that Elder Jie Xiu said that he was here, looked around with a smile, nodded and said: "Yes, this is really a historic meeting, in the past, our cultivation realm has long known about the existence of your underground human beings, but there has been too much contact, but history has gone through countless years, and that final time node is about to come, all of us, whether it is an above-ground human or an underground human being, are waiting, the moment when we enter the future, the higher authorities sent me here, It is intended to cooperate with the people of our dungeon, enter the future together, and open the ultimate secret of the moon. ”

Great Elder Jie Xiu also laughed and said: "We are all cultivators, and we are happy to speak, yes, we also got half of the key to the moon by accident, and it may be fate, according to the legends of our previous elders, it was still in ancient times, in the Kunlun Mountain area, there was a local tribal elder who handed us a sword hilt in the dungeon, and the kind of tribal elder at that time seemed to be called Haotian, At that time, our Great Elder and that Elder Haotian became good friends by chance, according to what Elder Haotian said, the hilt of the sword has a great relationship, it is the key to whether or not it can enter the future, and it is also the key to unlocking the true dusty history of the moon, not to mention the preciousness, just like that, since that time, our dungeon has been keeping and protecting the hilt of the sword until today. When Elder Jiexiu talked about the moon's activation key and the hilt of the sword, all the elders present also pricked up their ears and listened carefully, because they were also very concerned about the activation of the moon, and their hearts were also full of curiosity.

My master listened to Elder Jie Xiu talk about some of the history of the sword hilt, and he also listened carefully there, when Elder Jie Xiu finished introducing it, my master also nodded frequently, and said: "I didn't expect that after these thousands of years, it is not easy for you to keep the sword hilt intact, that sword is really too important, but unfortunately our Xiuzhen Alliance failed to get the sword blade, it is really a pity, this time the alliance asked me to come over mainly to talk about the sword hilt, to see if we can hand over the sword hilt to our alliance for safekeeping, Because in the moon, there are very important items of several elders of our alliance in the ancient period, that is, the hope for entering the future, I wonder if you elders can agree to our request? ”

After hearing my master's words, there was a brief silence in the hall for a few seconds, but after a while, the hall resounded with the voices of several elders, and my master was not in a hurry to come up with a result, but sat there quietly waiting.

Grand Elder Jiexiu, who was sitting across from my master, did not sit there like everyone else, but sat there quietly without speaking, listening to the chatter around him without moving.

Then the hall fell into an eerie silence, and my master knew that they were exchanging opinions in a special way of communication, like telepathy, which was unknown to outsiders.

My master sat in his seat and waited with a smile, and after a short time, he heard Elder Jiexiu say with a smile: "Hahaha, okay, it's decided like this, Master Jueming just now we elders discussed it together, and we all agreed to hand over the hilt of the sword to your alliance, and we formed an alliance and walked into that future together." "That's great! On behalf of my alliance, I would like to express my gratitude and welcome, and here we are in this moment, we are in an alliance! My master got up and said, and the Great Elder Jiexiu who was sitting opposite also stood up at the same time and walked towards each other, and the palms of the two people struck together, which was like an incomparably sacred oath to us cultivators, and at the same time, they said loudly in their mouths: "Alliance is one, never turn your back!" The elders sitting around also applauded, and the scene was extremely enthusiastic.

My master's trip to the underground was so simple and successful, and he reached an alliance with the humans in the dungeon, which is a big deal, and Master wants to take the hilt of his sword and rush back to the alliance headquarters to report the situation here.

So, my master put forward the idea of rushing back immediately with the hilt of the sword, and the Great Elder Jie Xiu nodded in agreement without ink, and listened to the Great Elder Jie Xiu say: "Master Jueming, I also have this intention, and I will do it right away without further ado, I can't hide it, during this period of time, our dungeon here is not very peaceful, there are some alien evil forces waiting for the opportunity to wreak havoc, we have already had some people die in their hands, although we have repelled their attacks many times, but there are also casualties among each other." You come with me to see the hilt of the sword, and then I will arrange for someone to escort you back with the hilt. My master nodded, thinking that these evil forces have a really keen sense of smell, and they have already touched here, but it is better to bring this sword hilt back, so that the people here in the dungeon will no longer be disturbed by them, and there are many cultivators in the alliance compared to the dungeon, so they can better protect this sword hilt.

Grand Elder Jiexiu led my master and a group of elders to the front of this hall, a circular open space surrounded by white light, when everyone stood still, they saw that the circular white light on the ground kept flickering, and when the brightness reached a dazzling level for a moment, a light curtain was generated in the white light, enveloping all the people in it, and the people disappeared in place.

There was only a moment of suffocation, and when Master looked at the surrounding scene again, it was no longer in the hall on the second floor, but according to Grand Elder Jiexiu, this was the highest room in the building, and the hilt of the sword was kept here.

My master found that this room was not very large, and it was more than 100 square meters as far as the eye could see, but my master felt that the surroundings of this room were wrapped in a very special energy field, and there was an invisible pressure imprisoning the surroundings.

In the center of this room, there is a transparent glass container, in which a black and shiny hilt lies quietly there, this is the hilt of the sword, there are nine dragon-shaped patterns on the hilt, it looks vivid as if it is about to take off, the dragon's mouth is facing the tail of the hilt, it looks like there is an invincible momentum, so that people unconsciously want to surrender from the bottom of their hearts when they see it.

Even when the well-informed master saw the hilt of this sword, he couldn't help but sigh, this divine sword really gave people a different feeling, and if it was in good condition, it would be so powerful.

My master was still thinking about his thoughts, when he saw the words in the mouth of the elder Jiexiu on the side, and at the same time quickly made a few handprints on his hand, and when the elder Jiexiu made the last handprint, he saw that the hilt of the sword in the glass container slowly rose and floated in the air.

At the same time, he instructed an elder to take a wooden box and put the hilt of the sword into it, my master looked at it with some doubts, and the elder Jie Xiu explained: "This hilt is very magical, it has its own space, so unlike other items that can be put into some of its own space, this hilt can't put it into any space, it's very strange, so I can only prepare a wooden box for you." "My master suddenly said in his heart: It seems that this escort task should be doubly careful.

My master took the wooden box and carried it on his back, and also recited the mantra in his mouth, and made a few handprints, and saw that the wooden box behind my master slowly disappeared in the eyes of everyone.

Grand Elder Jie Xiu couldn't help nodding when he saw this, and secretly said in his heart that this Jueming Master was really powerful, and he applied the blinding method so skillfully. At the same time, he called a few elders beside him, and listened to him say: "Qin Ming and Xin, you two elders, this time I will trouble you to escort Master Jueming back to the headquarters of the Ground Alliance safely." "Yes! We're done! The two of them stepped out of the crowd and responded loudly.

My master looked at them, smiled and nodded, after all, everyone is familiar with each other, and there is no nonsense, so my master and their group took the transportation they came to back to the entrance of the dungeon.

Ziming and Xue'er, the two husbands and wives, they still followed all the way, and when the three of us stood at the entrance of the dungeon again, we heard Ziming say loudly to a few of us: "Brother Jueming Dao, take care all the way!" We are waiting here for Qin Ming and Brother Xin, you to return safely! As we spoke, we saluted each other, and the three of us stepped into the teleportation array again.

I saw a burst of brilliance in the teleportation array, and a few of us slowly disappeared.
