Xiao Nian had been identified as the heir of the family before, so he was still very familiar with the ancestral land of the family, and when he came to the lake, he searched a little and opened the entrance to the lake!

Whoa!

The surface of the water slowly disappears, and finally a huge dungeon is revealed!

"It's ...... Chiyou Underground Palace? ”

Lu Yuan was slightly stunned, but he felt a little incredible.

"No, this is not the Chiyou Underground Palace, this is the place where the ancestor lived before, only by entering here, can you have the opportunity to reach the Chiyou Underground Palace!"

Lu Yuan nodded slightly, indeed, although this huge underground palace is very magnificent, but according to the specifications of Chi You's life back then, such a dungeon is too small.

Several people are well-cultivated existences, even if the underground palace is some distance away from them at this moment, they still jump down directly, not only that, Lu Yuan has always blocked this place with his divine thoughts, unless he is also a master of the saint realm, he will not find the movement here at all!

In the end, the four of them found the entrance to the underground palace, and after the gate of the underground palace was opened, Lu Yuan suddenly saw that the river water above was irrigated again, and after everyone entered the underground palace, the gate was closed again, and those rivers covered the entire underground palace again.

In the dungeon, no one has been here for many years, so here, I can't feel any breath, only the smell of corruption reaches the tip of everyone's nose.

Although it was already a dungeon thousands of years ago, it still remains the same as it was then.

Lu Yuan took a slight look, this is probably a place to live, Ao Xiao should have lived here for a long, long time, and many things here are similar to the decorations of the Dragon Clan, it can be seen that even if Ao Xiao left the Dragon Clan, he still misses the race that gave birth to him and raised him.

On top of the stone wall, there is a picture scroll.

On the picture scroll is a pair of lovers embracing each other, the man is handsome and extraordinary, and the woman is also captivating, but above this woman, there is a distinctive feature that shows her identity.

That's the conspicuous horn.

"Sure enough, this woman should be Chiyou's daughter, but I don't know if this is Chiyou's eldest daughter or the youngest daughter......"

Lu Yuan sighed, the Jiuli Nation back then was also a legend in the ancient world of China.

According to Lu Yuan's understanding, Chiyou had two daughters, the eldest daughter Jiaoxi and the youngest daughter Meng Ying, both of whom were rare heroines, but after the defeat of the Jiuli Nationality, the whereabouts of Chiyou's two daughters were also unknown.

Now it seems that one of the daughters should be married to Ao Xiao, and the two of them are like fairy couples hiding in this underground palace, giving birth to children and living a happy life.

In fact, Lu Yuan originally complained about Ao Xiao, but now, he understands Ao Xiao a little, and after having a family, there are some things that really don't need to be cared about too much.

"Patriarch, after the ancestral underground palace, it is the Chiyou underground palace, but our ancestors have never passed down the method of opening the underground palace, so we can only rely on the patriarch!"

Xiao Nian can only do this step, the way to open the dungeon back then should only be owned by Chi You's daughter, even if Ao Xiao and her are husband and wife, Chi You's daughter should not tell Ao Xiao the secret of opening the dungeon.

Several people walked through the underground palace where Ao Xiao lived, and sure enough, they saw that in the cave where they lived, there was a stone brick that could be moved.

Open the stone bricks, and a space that can probably accommodate a person appears.

"Xiao Nian, you are behind me, Lao Feng, you are the last."

Lu Yuan arranged it, and then the four of them walked down in an orderly manner.

At first, it was a little crowded, but in the back, it suddenly opened up, and finally it became a broad road!

Lu Yuan was slightly stunned, and sure enough, as soon as he arrived below, he felt a strong sense of slaughter!

The Jiuli nationality started with the war back then!

At the beginning, as the heir of the Shennong clan, Chi You originally did not have much real power, but with his strong combat effectiveness, he forcibly opened up the Jiuli country from the rule of Shennong Qing Emperor and Emperor Bai, which is enough to prove how warlike this Jiuli country was back then.

This is also the reason why Chiyou was not recognized by the Five Emperors, originally the Five Emperors had already divided the ancient Kyushu into governance, but there was a Chiyou, and it was the kind that was murderous at every turn, who could stand it, so the conflict between the Five Emperors Group and Chiyou would become bigger and bigger, and finally it reached the point of inextricability!

Lu Yuan also understood Chi You's choice, under the background of the time, he had no other way than to fight to the end.

If he didn't lead the people of the Jiuli Nationality to resist, the Five Emperors Group would not be able to let him continue to develop.

It's just that Ao Yuan, the patriarch of the Golden Dragon back then, although he also admired Chi You in his heart, he still chose to help Orthodoxy, after all, Chi You is like a time bomb, and no one knows when this madman will fight you.

The dragons don't want to care about so many things, in fact, the dragons are very lazy, they don't even want to talk much, the dragons' favorite things to do in current words are eating, sleeping and popping, oh, by the way, and they like to collect rare treasures.

The dragon clan really doesn't have much interest in who rules this world, he just wants to rule the world is a stable figure.

At least Emperor Xuanyuan is much more stable than Chiyou.

This also led to the dragon clan making that choice, and this choice may have also changed the trajectory of the dragon clan.

Walking on this ancient road, Lu Yuan began to have a trace of conjecture in his heart.

If the Golden Dragon Patriarch in his body had chosen to help Chi You, then Chi You might not have lost, and the Dragon Clan might not have been slaughtered by the Dragon Slayer controlled by Xuanyuan Yudao.

It's just that what happened has already happened, even if Lu Yuan has now achieved the saint realm, he has no way to change what has happened.

The ancient gate finally appeared in front of everyone.

"Shake the Mountain!"

Lu Yuan's eyes were slightly cold, he didn't expect that the Chiyou Underground Palace was actually built with Shaking Mountain Stone, although the Shaking Mountain Stone was not as strong as basalt stone in terms of solidity, but it was also a rare solidity in the ancient world at that time, it seems that this should be the real Chiyou Underground Palace, otherwise with Chiyou's temperament, he would never waste so many Shaking Mountain Stones to build a fake underground palace!

Of course, if he hadn't really seen the dungeon appear in front of him, Lu Yuan would never have believed that there would be a Chiyou dungeon here, and the most important thing was that he had been in Ao Xiao's dungeon, and Lu Yuan didn't even find this Chiyou dungeon when he opened his consciousness!

Looking at it now, Lu Yuan really saw that there seemed to be a dim light in the sky, and according to Lu Yuan's speculation, it should be the formation that played a role in it.

Now Lu Yuan began to be curious, who was the person who helped Chi You build the underground palace back then, and why was his formation technique far better than that of the Shennong Qingdi at that time in Lu Yuan's opinion?

Otherwise, why did the Five Emperors Group come here so many times, but they didn't find the Chiyou Underground Palace.

"Xiao Nian, did your ancestor record what was in the Chiyou Underground Palace?"

Lu Yuan suddenly asked.

Xiao Nian shook his head, and continued: "When the ancestor left, he just said that the Chiyou Zhan map was hidden in the underground palace, but he would not tell the descendants how to open the underground palace, if there are children in the descendants of the Xiao family who are destined for the underground palace, one day, the underground palace will see the light of day again!" ”

Lu Yuan savored this sentence carefully, he understood Ao Xiao's character, since he had lived near the Chiyou Underground Palace all his life, it was absolutely impossible not to want to open the Chiyou Underground Palace, and the sentence he left should contain the information of opening the Chiyou Underground Palace, but the descendants of the Xiao family have never understood Ao Xiao's meaning.

Looking at this magnificent palace, Lu Yuan gave up his plan to open it directly by force.

There is also a huge difference between basalt and mountain-shaking stone, that is, although a single basalt block is much stronger than a mountain-shaking stone, the mountain-shaking stone is far easier to build into a city wall than a basalt stone, and after it is built, the strength of the mountain-shaking stone is much higher than that of a single mountain-shaking stone.

Lu Yuan believed that not to mention that he was only a saint in the early stage of cultivation, even Emperor Xuanyuan, who was at the peak of the saint back then, might not be able to break through this ancient city gate by force.

Lu Yuan encountered difficulties here, but tonight, there was more than one wave of people coming to Chi You's hometown.

"They look like they're already in......"

Still by the same lake, the two figures whispered.

"I didn't expect that Xiaolong to be so scheming, when I saved Xiao Nian, I knew that he was making a move for the big secret hidden by the Xiao family, and sure enough, now, this guy is a little impatient!"

"Don't underestimate him, Emperor Xuan has already said that this kid should be a saint realm cultivator now, and the two of us together may not be his opponent!"

The other voice seemed a little unconfident, this kid, when did he get in front of them?

"Hehe, just the two of us, it's true that we don't have enough confidence, but what if it's an outsider......"

"What did you say!"

The figure suddenly became acute, and at this moment, a black vortex suddenly opened not far from them.

"It is said that Chiyou is an ancient demon god, do you think that Chiyou's title of demon god is just a simple title?"

The voice that spoke before was full of madness at the moment, and then he seemed to be worshipping: "Who would know, there is also a cave of extraterritorial demons in the Chiyou Underground Palace, haha, this time, I will let Lu Yuan's group of people die here!" ”

The water of the lake became muddy again, and huge waves were constantly generated, all of which seemed to be the end of the world!
