It is recorded in historical books that the Great Wall was a huge military project built by the First Emperor in ancient China to resist the invasion of the nomadic tribe alliance in the north of the North. The total length is 21,196 kilometers, which is very vast!

This project used nearly one million laborers to build the Great Wall, accounting for one-twentieth of the total population of the country at that time. It had no machinery and was completed by manpower. The working environment was also high mountains and steep cliffs and deep valleys, which was very difficult, which triggered a rebellion for the people.

However, in later generations, everyone who has visited the Great Wall was amazed at its majestic momentum. It gathered the wisdom, will, perseverance and tolerance of the ancients. Therefore, the Great Wall is a rare treasure and an extraordinary cultural relics and monument. It symbolizes the indestructible and eternal will of the Chinese nation, and is the pride of the Chinese nation.

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

However, how could those ordinary people who were playing on the Great Wall know that deep underground in the Great Wall, there is a huge underground palace and cemetery built by the First Emperor.

At this season, there are still many tourists on the Great Wall. Liu Xuan took Qiao San to take the helicopter prepared by Yao Chenshan and passed through the main trunks of the Great Wall, which attracted the attention of many tourists. After all, no one has ever taken a helicopter to visit the Great Wall, and his identity is definitely not ordinary.

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

Moreover, the patterns formed by the Great Wall are completely sorted in a certain array, and seem to be a large array of connections. As the helicopter moves forward, Liu Xuan's feeling becomes stronger.

"Master Liu, what's wrong!" Qiao San asked in confusion when he heard Liu Xuan say something inexplicably.

"Nothing!" Liu Xuan shook his head and did not say anything to Qiao Sanduo. Even if he said that, the other party would not understand.

The helicopter was still moving forward at a constant speed, and the scenery below was indeed retreating in a well-organized manner. The underground palace cemetery of the First Emperor was located in the center of the Great Wall. Nearby, after the real underground palace cemetery of the First Emperor was discovered, it was blocked by Yanhuang and ordinary people were not allowed to approach.

"Land down first at the beacon tower in front!" Liu Xuan hurriedly shouted to the driver.

"Yes, Mr. Liu!" The pilot was Tenglong's guardian, so he naturally knew Liu Xuan's identity. He heard his order and quickly pulled the control rod and let the helicopter fly slanted towards the beacon tower that Liu Xuan said.

The helicopters are all helicopters and direct landings. In addition, the pilot assigned by Yao Chenshan to Liu Xuan is top-notch, so he actually landed the helicopter directly and steadily on the beacon tower.

Liu Xuan jumped off the helicopter, then jumped straight off the beacon tower, and before he arrived at a corner of the wall below the beacon tower, he saw his right arm instantly enter a dragon-making state.

After watching the beacon tower for a while, he raised his golden palm and immediately rushed towards a position on the wall.

Boom! ~

A burst of stone chips flew, and even a piece of the nearby Great Wall trembled. When the stone chips dissipated, Liu Xuan squatted down and moved the stones that had been smashed away by himself.

Brush! ~

Qiao San didn't know what Liu Xuan was doing, so he jumped from above in confusion. However, when he saw Liu Xuan clearing out the collapsed position and revealing the situation inside, he immediately asked in confusion: "Master Liu, what is this?"

At this time, under the gap, there were circular patterns with patterns entangled with each other. Even during the day, the patterns still flashed with a faint light, and it was obvious that a stream of rich aura floated out of the gap.

Liu Xuan frowned and looked at the pattern and explained: "This is a formation, and it is a small formation! It is part of a large formation!"

Seeing this pattern, Liu Xuan knew that he was right. The connection between the Great Wall is indeed a large formation, and many small formations are connected.

Moreover, this large array is built on a large spiritual vein, so this small array is not activated by spirit stones, but is activated by the spiritual energy gathered from the spiritual vein. Otherwise, the spiritual energy emitted from the gap would not be so rich.

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

Liu Xuan was sure that the First Emperor built the Great Wall not simply to resist the enemy. According to Yanhuang records, the First Emperor had unparalleled military power. With his personality, his personality was definitely not to build the Great Wall to defend against foreign enemies, but to draw his sword to attack and attack the foreign enemy Huanglong!

However, Liu Xuan didn't know what the role of this formation was. It was worthy of the First Emperor's great trouble, and it was so exhausting that the people and money were directly ruined.

When the Wor family in the capital was eradicated, the Wor family also explained that the purpose of Ise Palace was to push it to the Great Wall. What is the purpose of Ise Palace?

Liu Xuan couldn't understand many things, but he felt a vague feeling that these things were inseparable from him in the end.

Liu Xuan returned to the helicopter and checked the two beacon towers and a pass again. He also found a formation drawn with ancient patterns, which was also surging with rich spiritual energy. This shows that there must be a large spiritual vein under the Great Wall. However, the spiritual energy of this spiritual vein was suppressed and absorbed by the large array, so it could not be emitted. This formation was based on this spiritual vein.

However, Liu Xuan did not find out the arrangement of all the small arrays, and it was difficult for him to know which kind of large array this was from the inheritance information of Xuanyuan Huangdi!

"Mr. Liu, where will we go next?" the helicopter pilot turned to Liu Xuan and asked.

"No need, just drive towards the center!" Liu Xuan shook his head and said.

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

The center of the Great Wall is among several mountains, which is basically sparsely populated here. Except for some distant donkeys, no one will come here. However, after the underground palace and cemetery was discovered, Yan Huang has sent people to secretly whistle here to stop the ordinary people approaching.

But at the center of the ground, a huge crack spreads open, and under the crack is a thick iron gate made of unknown material.

This gate does not stand up vertically, but goes down vertically. Anyone who has entered the underground palace and cemetery knows that under this gate are a long staircase.

In addition to this door that goes straight into the underground palace, there are actually 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 mechanisms are open at other times. Even the Heavenly-level supernatural practitioners dare not say that they can safely avoid all mechanisms.

The most important thing is that when entering from other directions of the underground palace and cemetery, almost all the mazes faced, and the location of the maze's way out is still changing, and various poisonous gases will be released in the maze. This poisonous gas cannot even be said to be safe and sound, and those who enter the maze have never walked out again.

This also fully demonstrates the wisdom of ancient people. Such a magnificent underground palace could be built with just hands and without any high-tech help.

So, this time, not many people were bored, and were waiting for the opening of the underground palace cemetery outside the huge crack.

Moreover, almost everyone from the various cultivation sects and cultivation families in China came. In ancient times, a martial arts conference could be held. However, each cultivation sect was far apart and was on guard against each other, because after entering the underground palace and cemetery, if you really encounter any elixirs or treasures, there would definitely be a fight between each other.

There were two sects who once fought for a pill that could break through half a step innate nature, but they all killed each other and suffered losses, and were finally destroyed by the sects that came from behind.

This time, a total of 4 people came to Qingyun Sect. The leader of Qingyun Sect was the strongest sect leader, who had the strength of the half-step innate peak. His purpose of coming to the underground palace cemetery this time was to find a way to break through to the innate! The other three people also had the strength of the heavenly level, because this time Qingyun Sect got a residual picture deep in the inner palace and knew a path to the depths of the cemetery. People with low strength were definitely looking for death when entering the depths, so this time, no people from the earthly level came.

At this time, an old man walked towards the four people in Qingyun Sect. As soon as the old man approached, the three heavenly steps of Qingyun Sect stood up with caution.

"The head of Qingcheng Sect, Wu Dayong, I wonder what you are doing?" The leader of Qingyun Sect recognized the old man's identity.

"Master Li Jing, I haven't seen you for many years, and your style is still the same!" Wu Dayong said with a laugh.

"It's all the time to be an old man, what kind of style?" Li Jing smiled faintly and said, "President Wu is here to find me and tell me if you have anything to do!"

"Since Master Li is so quick and easy to speak, I'll just say it." Wu Dayong hurriedly said: "Now the name of the new leader of the Xuri Sect is very loud, and he was even more powerful when he was in Tieling. However, his power was exposed to our Qingyun and Qingcheng. Does Master Li want to swallow his anger?"

If we say that the hatred between Qingcheng Sect and Liu Xuan is really big and cannot be resolved, and these cultivation sects care about face issues. Of course, Qingcheng Sect cannot just let it go with Liu Xuan. Wu Da’s purpose of finding Li Jing is very simple, that is, to join forces to destroy Liu Xuan!

"Hmph, kill me, the elder of Qingyun Sect and use my Qingyun Sect as a stepping stone to establish his authority. This matter is not that easy. Moreover, listen to the reports of the disciples who have returned from Tieling! The Xuri Sect still has the method to become a mutant, and I want to know too!" Li Jing sneered.
