It is recorded in the history books that the Great Wall was a large-scale military project built by the First Emperor in ancient China to resist the invasion of the nomadic tribal alliance in northern China. The total length is 21,196 kilometers, which is very vast!

This project mobilized nearly one million laborers to build the Great Wall, accounting for one-twentieth of the total population of the country at that time, without any machinery, all by manpower, and the working environment was very difficult with lofty mountains and deep cliffs, so it triggered a rebellion among the people.

However, in later generations, all those who have been to the Great Wall are amazed by its majestic momentum, it brings together the wisdom, will, perseverance and endurance of the ancients, therefore, the Great Wall is a rare treasure, but also an extraordinary cultural relics and monuments, it symbolizes the indestructible and eternal great will and strength of the Chinese nation, is the pride of the Chinese nation.

Of course, these are only what ordinary people can see from history books.

However, how could those ordinary people who played on the Great Wall know that in the depths of the underground of the Great Wall, there is a huge underground palace mausoleum built by the First Emperor.

At this time, there are still many tourists on the Great Wall, Liu Xuan took Qiao San to sit in the helicopter prepared for him by Yao Chenshan and went straight through the main trunks of the Great Wall, which attracted the attention of many tourists, after all, no one has ever come to the Great Wall by helicopter, and his identity is definitely not ordinary.

"Something is wrong!" Liu Xuan looked at the torso of the Great Wall that kept flashing below, and frowned slightly, because the winding Great Wall actually looked like some kind of pattern, and the information of this pattern seemed to be recorded in Emperor Xuanyuan's inheritance information.

Moreover, the lines formed by the Great Wall are completely sorted according to some kind of array, which seems to be a kind of large array, and as the helicopter moves forward, Liu Xuan's feeling becomes stronger.

"Sect Leader Liu, what's wrong!" Qiao San heard Liu Xuan suddenly say something inexplicably, and immediately asked suspiciously.

"Nothing!" Liu Xuan shook his head, and didn't say much to Qiao San, even if he did, it was impossible for the other party to understand.

The helicopter is still moving forward at a constant speed, and the scenery below is indeed going backwards in an orderly manner, the underground palace cemetery of the First Emperor is in the center of the Great Wall, and the vicinity has been blocked by Yanhuang after the real underground palace cemetery of the First Emperor has been discovered, and ordinary people are not allowed to approach.

"Descend on the beacon tower in front of you!" Liu Xuan hurriedly shouted at the driver.

"Yes, Liu Shao!" The pilot was Tenglong's security person, so he naturally knew Liu Xuan's identity, and when he heard his order, he hurriedly pulled the control lever and directly let the helicopter fly diagonally towards the beacon tower that Liu Xuan said.

The helicopters were all helicopter and landing, and the pilot sent by Yao Chenshan to Liu Xuan was top-notch, so he landed the helicopter directly and steadily on the beacon tower.

Liu Xuan jumped down from the helicopter, and then jumped straight off the beacon tower, and before he came to a corner under the beacon tower, he saw that his right arm instantly entered the state of dragonization.

After looking around the beacon for a while, he raised his golden palm and immediately blasted down at a position on the wall.

Rumble! ~

There was a burst of stone chips, and even a section of the Great Wall nearby trembled a little, and when the stone chips were gone, Liu Xuan squatted down to move the stones that had been blown down by himself.

Brush! ~

Qiao San didn't know what Liu Xuan was doing, and he jumped down from it in confusion, but when he saw Liu Xuan clear out the collapsed location and reveal the situation inside, he immediately asked suspiciously, "Sect Master Liu, what is this?" ”

At this time, under the gap, there are circular patterns that are intertwined with each other, and even in this daytime, this pattern is still flashing with a faint light, and a rich aura can clearly float out from the gap.

Liu Xuan frowned and looked at this pattern, and explained: "This is a formation, and it is a small formation!" It's part of a larger array! ”

Seeing this pattern, Liu Xuan knew that he had guessed correctly, the connection of the Great Wall of Ten Thousand Miles was indeed a kind of big array, or a lot of small formations were connected.

Moreover, this large array is still built on a large spiritual vein, so this small array is not driven by spirit stones, but by the aura of gathering spiritual veins, otherwise, the aura emitted by this gap will not be so rich.

However, what made Liu Xuan even more puzzled was that these patterns were all ancient patterns, and the First Emperor actually knew how to use them and used them in such a vast project.

Liu Xuan can be sure that the First Emperor built the Great Wall not simply to defend against the enemy, according to the records of Yan Huang, the First Emperor is unparalleled in force, and with his character, he is definitely not building the Great Wall to defend against foreign enemies, but drawing his sword to attack, and smashing the foreign enemy Huanglong!

However, Liu Xuan didn't know what the effect of this big array was, it was worth the first emperor's great effort, the people and the money, and directly ruined the Great Qin Dynasty.

When the Fujia family in the capital was eradicated, the Fujia family also explained that the purpose of the Ise Palace was to push to the Great Wall, and what was the purpose of the Ise Palace?

Liu Xuan didn't understand a lot of things, but he had a faint feeling that these things were inseparable from him in the end.

Before Liu Xuan returned to the helicopter, he checked the location of two beacon towers and a pass in a row, and also found a formation drawn with ancient patterns, and it was also surging with a rich aura, which showed that under the Great Wall, there must be a very large spiritual vein, but the aura of this spiritual vein was suppressed and absorbed by the large array, so it could not be emitted, and this large array was built on the basis of this spiritual vein.

It's just that Liu Xuan didn't find out the position of all the small arrays, and it was difficult for him to know what kind of big array this was from the inheritance information of Xuanyuan Yellow Emperor!

"Liu Shao, where are we going next?" The pilot of the helicopter turned to Liu Xuan and asked.

"No need, go straight to the center!" Liu Xuan shook his head and said.

"Okay!" The pilot nodded, and the helicopter started again, heading for the center of the Great Wall.

The center of the Great Wall is in the middle of several mountains, which are basically inhabited, except for some distant donkeys, no one will come here, but since the discovery of the underground palace cemetery, Yan Huang has sent people to conduct secret sentinels here to stop those ordinary people who are approaching.

In the very center, a huge crack spread out in the ground, and beneath that crack was a heavy, iron gate of unknown material.

This gate does not stand vertically, but vertically down, and those who have entered the underground palace cemetery know that under this gate is a long staircase.

In addition to this door that goes straight into the underground palace, in fact, there are many people who try to dig tunnels in other places to enter the underground palace cemetery when the underground palace cemetery is not opened, but very few people can come out. When this door is automatically opened, most of the mechanisms in the underground palace cemetery will be closed, and all the mechanisms are fully open at other times, even the heaven-level ability walkers dare not say that they can avoid all the mechanisms safely.

The most important thing is that when you enter from other directions of the underground palace cemetery, you will almost face a maze, and the location of the way out of this maze is still changing, and various poisonous gases will be released in the maze, and this poisonous gas will not even dare to say that it can be resisted unharmed, and those who enter the maze have never come out at all.

This also fully shows the wisdom of the ancient people, with only their hands, and without any high-tech help, they can build such a magnificent underground palace.

Therefore, this time, not many people were bored with themselves, waiting for the moment of opening of the underground palace cemetery outside the huge crack with peace of mind.

Moreover, almost all the people from the various cultivation sects and cultivation families in Huaxia came, and in ancient times, they could almost hold a martial arts conference, but each cultivation sect and family was far away from each other, and they were wary of each other, because after entering the underground palace cemetery, if they really encountered any pills or treasures, there would definitely be a fight between them.

There used to be two sects in order to compete for an elixir that could break through the half-step innate innate pill, but as a result, everyone who came was killed and defeated, and finally they were wiped out by the sect that came from behind.

This time, a total of 4 people came to Qingyunmen, and the leader was the strongest master of Qingyunmen, with the strength of the half-step innate peak, and the purpose of his coming to the underground palace cemetery this time was to find a way to break through to the innate one! And the other 3 people also have the strength of the heavenly rank, because this time Qingyunmen got a remnant map of the depths of the inner palace, and knew a path to the depths of the cemetery, and the people with low strength entered the depths to definitely look for death, so this time they did not bring the people of the ground level to come.

At this time, an old man walked towards the four people of Qingyunmen, and as soon as the old man approached, the three heavenly steps of Qingyunmen stood up vigilantly.

"The head of the Qingcheng faction, Wu Dayong, I don't know what you have to do?" The master of Qingyun Gate recognized the identity of the old man.

"Master Li Jingmen, I haven't seen you for many years, but your demeanor is still the same!" Wu Da said with a laugh.

"It's all an old man, what else do you have?" Li Jing smiled faintly: "Master Wu came to me and said something directly!" ”

"Since Master Li is so quick to speak, I will also say it directly." Wu Dayong hurriedly said: "Now the name of the new leader of the Rising Sun Sect is very loud, and when he was in Tieling, he was even more powerful, but his divine power is on the heads of our Qingyun and Qingcheng, does the master of the Li Sect want to swallow his anger?" ”

To say that the grudge between the Qingcheng faction and Liu Xuan is really big and cannot be resolved, and these cultivation sects are very concerned about the problem of face, of course the Qingcheng faction can't just forget it with Liu Xuan, Wu Da's purpose to find Li Jing is very simple, that is, to join forces to destroy Liu Xuan!

"Hmph, kill my Qingyunmen elder, use my Qingyunmen as a stepping stone to establish power, this matter is not so easy to calculate, and besides, listen to the report of the disciples who came back from Tieling! The Cult of the Rising Sun still has a way to make people become deviants, and I want to know that too! Li Jing sneered.

"Then I'll tell the truth to the Li Sect Master, Liu Xuan already has a half-step innate strength, and he has the ability to mutate, and I am not sure that he can defeat him, so I want to join forces with the Li Sect Master to deal with Liu Xuan, and besides, the Rising Sun Sect has mastered the method that can make people have the ability to mutate, but not only the Li Sect Master is interested, I have also contacted other people, and I will definitely be able to leave Liu Xuan here forever without fail!"
