The inside of this tunnel cave is relatively normal, occasionally you can see a few bats and ants in the clouds, and it is the addition of these creatures that makes this cave have a trace of vitality.

Despite this, Yun Tian still didn't dare to be careless, who knows what dangers are in this cave, and where demons usually appear, it will not be safe.

Just walk slowly in the cave, after nine bends and eighteen bends, the front suddenly opens up, the cave has disappeared, and a majestic hall appears.

The main hall is up to 3,000 steps wide horizontally and vertically, it can fully accommodate 10,000 people, and people feel particularly small when they stand in it, especially in the four walls of the main hall, which is not an ordinary mountain stone, but a kind of jade full of fairy energy.

This hall is full of vitality, everywhere is full of misty gas, a stream of aura penetrates people's hearts, in this hall, Yuntian does not feel the existence of a little demon.

"That's not right, there is heaven and earth vitality everywhere here, and there is no trace of demon existence at all, why do you want to say that the demon weapon is suppressed here?" Yun Rou looked at the square hall and said with some confusion.

"I don't know, but behind the beauty, there is a mortal danger, so let's be careful. Yun Tian didn't think so, but carefully observed the bits and pieces around him, and refused to let go of the slightest.

Except for one entrance, the rest of the hall is absolutely sealed, and there is nothing strange about the smooth top of this jade wall, as if it was naturally formed.

And the floor of this hall is a kind of black fine sand, which is also unremarkable. But Yuntian has a feeling that there are absolutely hidden secrets in this hall.

Stone Temple!

Jade!

Sand!

Nimbus!

Forming an eternal picture, Yun Tian was in this stone hall, and suddenly had a kind of thought that he didn't want to leave, he hurriedly destroyed the true yuan spiritual qi, his mind was clear for a while, and all distracting thoughts disappeared.

"Huh, the vitality in this hall can actually affect people's spirits, fortunately I have practiced the spirit, otherwise I would have fallen into the path of this aura!" Yun Tian's heart palpitated, seeing that Yun Rou did not have any discomfort, he couldn't help but breathe a sigh of relief, Yun Rou's cultivation in the Golden Pill Realm, this bit of aura fluctuations, naturally could not affect her.

Knock! Knock! Knock!

Suddenly, the sound of war drums sounded in this stone hall, and the sound of war drums was deep, gloomy, and resentful. Every time the war drums sounded, the dense qi in the stone hall would dissipate a little, and after nine sounds, all the breath in the main hall disappeared, leaving only an empty stone hall.

"What is this?"

Yun Tian and Yun Rou stood side by side, looking at the vision of the stone hall, they were both taken aback, and then something even more surprising happened to them.

Suddenly, the stone hall trembled violently as if an earthquake had occurred, and a huge crack suddenly appeared in the fine sandy ground, and the crack was slowly getting bigger, and a deep black gas emanated from the crack.

I didn't know what this black qi was, Yun Tian still chose to dodge, he and Yun Rou took a few steps back and came to the entrance of the stone hall, so that even if they encountered danger, they could escape.

At this time, the ground of the stone hall suddenly collapsed, forming a square cave of three thousand steps, and the cave emitted a substantial black light, which was like a black sun, so that Yun Tian did not dare to look at it directly.

"Bang!"

Suddenly, a loud noise came from the depths of the earth, and in the eyes of Yun Tian, a huge canopy appeared, which was three thousand zhang long and one thousand zhang wide, wrapped in black mist, which looked particularly mysterious.

And just when the sky curtain came out, this stone mountain suddenly shook violently, and then in Yun Tian's shocked gaze, this huge stone mountain was actually pulled up by a strong force, and then this strong force disappeared instantly, Yun Tian's dark path was not good, and Yun Rou flew out of this stone hall quickly.

At the moment when Yun Tian and the others just flew out of the stone hall, the huge stone mountain suddenly shattered, turned into countless large stones, and fell into this cave on the ground.

At this time, there was an additional black canopy of a thousand zhang in the sky, which was the mysterious canopy that Yun Tian had seen before.

This canopy of heaven directly shattered the mountain, and flew out of the ground at an unknown depth, this mana, Yun Rou secretly sighed. You must know that only those strong people in the realm of heaven and man have the power to pull out mountains and reclaim the sea!

Yun Tian and Yun Rou stood in the sky, looking at the canopy above their heads, their hearts could no longer be described as shocked, and Yun Tian's heart was already surging.

"If my estimate is right, this canopy should be the suppressed magic weapon, but the magic weapon has been suppressed, how can it shake off the seal?" Yun Tian looked at this canopy-like thing and muttered.

"I don't know, this thing must not be a treasure weapon, most likely a Dao weapon, but why can't I feel the coercion of the strong? Could it be that this canopy of heaven is showing favor to us?" Yun Rou shook her head, and her words were shocking.

If this canopy of heaven is really a Dao weapon, how can that Dao weapon show favor to them!

It is absolutely impossible for the Dao Weapon to show favor to a person who has cultivated in the Manifestation Realm and the Jindan Realm.

At this moment, this canopy in the sky changed dramatically, and I saw that this canopy was shrinking rapidly at a speed visible to the naked eye, and finally turned into a scroll nine feet long and three feet wide.

Ancient Painting Scrolls!

The open scroll swayed in the sky, as if a gust of wind could blow it away. But Yun Tian knew that no matter how strong the wind was, it would be impossible to blow this scroll away, because this scroll could be a Dao weapon.

Dao instrument, Taoist instrument, is the magic weapon of possessing Taoism.

Yun Tian poured his spirit into his eyes, and he immediately saw this scroll in the sky clearly.

The background on this scroll is pitch black, and in the darkness, there is a huge space faintly, and there are thousands of dormant in this space, no, it should be countless ghosts and ghosts. And in the depths of this ghostly phantom, there is a high mountain faintly, and at the top of the mountain stands a "person" with a blurred face.

It was as if this was not a painting, nor was it a canopy, but a window, a gate, a window that could lead to an unknown space, a door that could lead to death.

There are three things on this scroll, one is the endless ghost, the other is the cave void that I don't know how big, and the last one is the "person" at the top of the current peak.

The endless ghostly shadows, although in the picture, seem to be a void of their own. Definitely not trivial.

Yun Tian knew that the magic weapon that became a cave was already a "Dao weapon" level existence, and the magic weapon had a spirit in it, and that spirit had attained the Tao and could cultivate itself, no less than a strong person in the immortal realm.

Looking at the various things in this scroll, Yuntian has determined that the ghost and the mountain in this scroll are a cave and void, and the "person" at the top of the high mountain is the machine spirit, the machine spirit that has attained the Tao.

Thinking that this was a Dao weapon, Yun Tian didn't have the slightest greed in his heart, he and Yun Rou glanced at each other, and each saw the shock in each other's eyes.

They couldn't help but be shocked, the magic weapon of the Dao weapon, if it is spread out, it can definitely cause a bloody storm, and even cause a war between immortals and demons!

Dao device, too rare!

"I don't know if my predecessors are ......."

Before Yun Tian finished speaking, the scroll in the sky sounded a sound fluctuation, "Your name is Yun Tian, right?" Haha, you think well, I am the instrument spirit of the Ghost Yuan Holy Diagram, and you are the descendant of the Ghost Yuan Sacred Diagram.........
