It turned out that at that time, Lu Yuan and Zhou Wanzhi were worried that something would happen if Gongsun left alone, so they secretly accompanied them for a while.

Sure enough, I happened to meet my senior sister Mu Rong.

After that, the four were separated. Lu and Tuesday continued to go to Xuantian Sect.

The two of them flew very fast, and it didn't take long for them to come to the gate of Xuantian Sect Mountain.

Lu Yuan looked at this familiar place and was full of emotion.

This is the place where he grew up in childhood, a sad land, but also a blessed land.

Zhou Wanzhi had only heard him talk about this, and when she came here today, she could also understand Lu Yuan's mood.

The current head of the Xuantian Sect, Gao Yang Zhenren, led the whole sect and gave him the highest courtesy welcome.

Lu Yuan first worshiped his mentor Qing Xuanzi, and then participated in a grand dinner.

After the banquet, Lu, Erren and Gao Yang came to the secret room and informed him of the purpose of their trip.

Gao Yang Zhenren looked dazed:

"I've never heard of anything like this before. Our Xuantian Sect has always been a famous and decent family, how could it be possible to bury the remains of the Heavenly Demon? Miss Zhou, could it be that you are mistaken?"

"I can't be wrong," Zhou Wanzhi said, "I'm sure that the stump is in the Xuantian Sect, but I really can't see where it is." ap..

Gao Yang Zhenren thought for a while and said, "Miss Zhou's demon trace technique, we have also heard of it a long time ago. If there are really stumps, then those demons will definitely kill again. When the time comes, it will inevitably be bloody."

He sighed and continued, "Without further ado, I will immediately arrange it and ask the disciples to use all kinds of supernatural powers to find the stump!"

Lu Yuan arched his hand and said, "Youlao is in charge!" ……

Outside the door, the rain rests.

Lu Yuan came to the tomb of Qing Xuanzi alone.

The wreckage of the Demon Suppression Tower was silent, as if it was silently telling the thousand-year-old situation of the Xuantian Sect.

Master, you have knowledge under the spring, and I hope to inform you of the whereabouts of the stump of the Heavenly Demon again.

He prayed silently in his heart.

But he also knew very well that after Qing Xuanzi transformed his own cultivation and remnant soul into Lu Yuan's body, there would never be anything left in the human world.

He stroked Qing Xuanzi's cold tombstone, sat down slowly, and fell into deep thought.

Zhou Wanzhi looked at him quietly from a distance, not daring to come over and say a word.

Lu Yuan just sat quietly, constantly recalling the scenes of his life with his ancestors.

But the consciousness did not stagnate. He still catches up on everything around him.

I don't know how long he sat there, but a flash of inspiration suddenly flashed in his mind, and he recalled Qing Xuanzi's words.

Many years ago, he absorbed Qing Xuanzi's cultivation and memories and found the whereabouts of the Silent Demon Sword. Look at the book

In addition, he also discovered another memory of Qing Xuanzi: deeper under the Demon Suppression Tower, there is a huge space.

It's just that when Qing Xuanzi's remnant soul wanted to probe down, it was blocked by a powerful force.

Because at that time, the Xuantian Sect was occupied by the Immortal Sect, so Lu Yuan didn't have time to think about it.

Now that the Immortal Gate has long been wiped out, and the huge space in Qing Xuanzi's memory will be where the stump is located?

As soon as he thought of this, Lu Yuan immediately probed his divine sense to the underground of the remains of the Demon Suppression Tower.

The spirit realm at the beginning of the fourth order was already a legendary-level existence.

Rao is so, and the search is still extremely difficult.

There are only a few messy wastes underground, and the occasional monster creature.

Under Lu Yuan's powerful divine sense, they retreated and fled one after another.

Those who cultivate the mystic have patience.

After this boring search lasted for more than an hour, his divine consciousness finally felt the power of an obstacle.

Lu Yuan was overjoyed.

It looks like there's really something!

In Lu Yuan's opinion, that layer of blocking power is quite like a weapon used by children when they play at home.

It broke through it without much effort.

A little further down, there is another layer of blocking power, but it is stronger than before

Some.

Lu Yuan still broke through with an understatement.

There are seventeen such powers.

For the last force, Lu Yuan still took a little effort.

However, in the face of absolute strength, all obstacles are in vain.

With a muffled sound, Lu Yuan's eyes suddenly lit up!

At this time, there is an infinite bright space.

From time to time, black lightning streaked in front of him.

The sound of a spell echoed softly in his ears.

What surprised him even more was that-

Not far away, there is actually a huge demon tower!

The Demon Suppression Tower emitted bursts of demonic energy, but no matter how they were released, they could only float in a small area outside the tower.

It seems that something ties them firmly around the tower.

Lu Yuan looked carefully with his eyes and found that there were a lot of pale yellow rune papers floating on the outside of the tower.

If it weren't for the true eyes of the unicorn, I wouldn't be able to see it normally.

Looks like my guess was correct! Sure enough, there was something under the tower.

It turns out that the real Demon Suppression Tower is in it!

With curiosity and vigilance, Lu Yuan's divine sense slowly swam over.

Approaching the side of the tower, an old voice suddenly sounded in his ears:

"After all these years, someone finally got here."

Lu Yuan was taken aback: Is there anyone else here? How did I not notice it?

However, it seems that the voice is not aggressive.

Thinking of this, Lu Yuan immediately said:

"Senpai! The juniors are polite!"

A pale yellow figure gradually appeared not far in front of him.

It is an old man with crane hair and a childish face and fairy wind bones.

Seeing Lu Yuan, the old man asked in a calm voice:

"Who are you?"

"I was a disciple of the Xuantian Sect."

"Oh? Was it?"

Lu Yuan simply told him where he came from.

At times like these, there is little point in deceiving.

After listening to Lu Yuan's words, the old man stroked his beard and smiled, "It turned out to be my disciple and grandson. Good, good, good. This seat is the founding head of the Xuantian Sect - Wuyazi."

No cliffs?!

Lu Yuan was taken aback.

"Senpai, you...... Didn't you die hundreds of years ago?"

Wu Yazi said, "That's right. So you're seeing my remnant."

Lu Yuan understood this time.

Xuantian Sect does have its own unique cultivation method in terms of preserving remnant souls.

Then, Wu Yazi told the story of the incident.

It turns out that more than 1,000 years ago, the Heavenly Demons invaded the human world. Many ancient powers defeated it and decomposed.

Wu Yazi is responsible for guarding the right leg of the Heavenly Demon.

As a casual cultivator, he guarded for nearly a thousand years.

Later, knowing that his end was near, he founded the Xuantian Sect and trained monks to continue to protect it.

To this end, he specially built two demon towers.

One specializes in suppressing the stumps of the Heavenly Demons, and the other suppresses the monsters that do not need to be killed for the time being, in order to convert their energy into the power to suppress the Heavenly Demons.

The two towers are inside and outside each other. If something happens to the outer tower, it will definitely cause chaos in the tower.

At that time, for the sake of secrecy, all the powers swore that they would not tell anyone the secret of the repression.

Therefore, their descendants only know that they are guarding something very important and dangerous.

As for what exactly, it is unknown.

So Qing Xuanzi only knew that he had to take care of the demon tower outside.

As for Rita, he had absolutely no idea.

Hearing this, Lu Yuan gradually understood Shangguan Yu's true intention of attacking Xuantian Sect many years ago.
