And when the foundation stone had risen to a height of seven feet, it ceased to rise and was fixed there. After the cornerstone was settled, a sonorous sound sounded under the cornerstone, as if it was made by the collision of metal, dull and harsh, and after a while, only a loud click was heard, and after the loud noise, the whole valley was completely silent.

Seeing this, the multi-eyed old Taoist jumped on the cornerstone first, and everyone followed closely behind, and they also jumped on the cornerstone. At this time, sure enough, in the four directions of the cornerstone, there was a circular hole the size of a zhang appeared out of thin air, looking down into the deep darkness, and it was impossible to see the situation inside.

"You fellow Daoists must be no strangers to the Four Elephants Gathering Spirit Array here, these four holes are the four formation gates of the Four Elephant Spirit Gathering Array. Of the four array gates, only this White Tiger Seven Star Array Gate was opened by the Qingniu real person, and he could enter from here. However, you must remember that when you will go down with the poor road, you must support your feet with the qi control technique and sink down at a uniform speed. This passage is about 100 zhang long, because the cornerstone of this door is made of a whole piece of Xuan Soul Jade, so in the process of going down, all Taoist friends must remember not to release their divine sense to check, otherwise once the Yuan Shen is absorbed by the Xuan Soul Jade, it will fall here, don't blame the poor Dao for not reminding. After the multi-eyed old man solemnly explained to everyone, he first used his mana to use the qi control technique, and the wind was under his feet, and he jumped into the hole in the White Tiger Seven Star Array Gate in the west.

One by one, everyone cautiously used the qi control technique, and also jumped into the hole and sank down.

Entering the hole is very different from the outside. This Soul Jade is really wonderful, it can emit a brilliant blue light in the dark, and the entire hole that shines is green. But standing on top of the cornerstone, you don't seem to feel any light below.

The distance of 100 zhang, under the condition that everyone has the heart to control the speed of zhì, it took a whole meal to go down to the bottom.

Although he was already familiar with the terrain below, Wu Yan was still deeply shocked after breaking away from the hole in the cornerstone and falling into the central square of a huge underground palace.

The cornerstone of the Soul Jade was just a little above the spatial dome of this underground cave. Below this, there was a huge underground cavern with a radius of about ten miles.

As if the ground had been hollowed out, the floor of the palace was about a hundred feet high from the dome above. The dome is inlaid with all kinds of gems and pearls, any of which is a priceless treasure in the secular world, but here it is like a clod of earth and rubble, randomly inlaid on the blue stone wall of the dome, and placed as stars dotting the night sky.

In the space of this Fang Dong Mansion, there will be no feeling of oppression at all. Standing in the middle of it, it is as if you are in another small world. The sky is blue, and the blue sky is full of stars of various sizes, which is very beautiful.

It's like a space that is forever in the blue night, with no day, only night when the stars twinkle.

The hole that everyone came down from was open in the sky dome at this time, as if it was a full moon with a black hole on the night of the entire sky dome, which was really weird.

Everyone fell to the ground, and many people looked at the scene in front of them in amazement, unable to speak for a long time. Among the twelve, only Mo Ao, Duomu, Boss Hu and Na Xiuyuan looked blank, and they didn't seem to be much surprised.

The crowd was now standing on top of a jade square about a mile in radius. On the four sides of the square, according to the orientation of the four elephants, there are four palace clusters. The style of the palace building is different in each place, and under the blue night, it stands quietly in the underground cave.

Although it is an abandoned underground cave mansion, at this scale, looking at the current immortal cultivation world, I am afraid that no sect or powerful monk can build such a brilliant and huge cave mansion.

However, the strange thing is that after so many years, this place has not been occupied by anyone or sect as a private cave house.

"Fellow Daoists, this palace on all sides was emptied more than a thousand years ago. Moreover, the forbidden magic circles in many places within it are still powerful, and if they break into it rashly, they will definitely be in danger. Therefore, please follow the poor road, and don't take the wrong path. The old man reminded him at the right time, and then walked towards the palace to the east.

Among the people, those who were familiar with the terrain knew that he was walking in the right direction, and those who were not familiar with the terrain naturally did not break in, so they all followed him and walked towards the palace complex.

Wu Yan knew that among this underground palace, the palace in the north was the Dao palace where the master of this cave mansion had cultivated, and the palace in the south was the place where the ancient teleportation array was located, and the palaces on the east and west sides should be the palaces of the disciples and Taoist masters of this cave mansion.

The palace group where everyone is going now is the palace where the original master and disciple of the cave house lived. Everyone followed the old way and walked all the way to the palace. Wu Yan secretly observed around as he walked, and Mo Ao followed behind Wu Yan and also looked around. After walking out of Baizhang, the two looked at each other secretly and nodded.

It seems that there are indeed disciples of the Demon Mansion hidden here. Many of the places were very clean and seemed to have been cleaned, while others were covered in a thick layer of dust, obviously unimportant and untouched.

Mo Ao made a careful gesture to Wu Yan, and Wu Yan nodded secretly. The crowd walked all the way to the stairs of the palace complex. I saw that the door of the temple above the steps of the temple was opened, and I walked through the door of the temple and entered the hall, but the inside was a ruin. Most of the houses collapsed and turned to gray stone, and the few remaining houses were also crumbling and could collapse at any time.

In the middle of the ruins was a strange tomb ten feet in diameter. The tomb was shaped like an inverted giant bowl, and the whole thing was closely attached to the blue rock of the main hall on the ground, without any gaps. On the four sides of the tomb, connected to the tomb were four strange black columns, about ten feet high. At the top of the pillar, four huge statues of green bull heads are carved lifelikely.

When everyone saw this tomb, their eyes lit up. It seems that this is the tomb of the green ox mentioned in the mouth of the old man.

"Fellow Daoist, could it be that this is the Qingniu Tomb you said?" Mo Ao observed for a moment, frowned slightly, and asked.

"Yes, fellow Daoists, don't be fooled by the green ox tomb you see in front of you. This was originally the hall of a large hall, and the ground was paved with solid green rock, and a few years ago, when Poor Road first came in, he witnessed this green cow tomb slowly rising from the bottom of the green rock. It's just that the forbidden array of this Qingniu Tomb is very strange, and it can actually make the tomb body and this Qingyan bond so closely. The old man nodded and said.

"Then how can we break the forbidden formation of this Green Ox Tomb and enter it?" everyone was puzzled, and several people asked this question at the same time.

"Daoist friend asked well, this is also the doubt of poor Dao. Although the poor path has some experience in the way of formation, if you want to break this forbidden formation, you still need to study and study it again. All the Daoists invited this time, if there is any Daoist who is proficient in the way of the forbidden formation, you may wish to refer to it together. The multi-eyed old man's eyes flashed, and he glanced at everyone meaningfully and said.

"What?

Indeed, before entering this underground cave, the multi-eyed old man patted his chest and assured everyone that after everyone came in, they only needed to contribute, and as for the way to crack it, he already knew it. Now that he said that, everyone was naturally very dissatisfied.

"Duomu Daoist, are you going to say, who can think of a way to crack it, once the tomb of the green cow is opened, you can take one more thing from the tomb?"

"Haha, of course Poor Dao didn't say that. However, although this matter was initiated by the poor Dao, how to solve it requires everyone's collective efforts, right? For those who contribute more to cracking the tomb of the green ox, if they can't get a little more benefits, it must be unfair. I don't know if Poor Dao said this, how many Daoists can agree?" said with a smile.

The crowd fell silent. Although everyone is secretly scolding in their hearts, if they really don't arrange it like this, I'm afraid that if they want to break through this green cow tomb, they really can't do it with their own ability.

Because, in the moment of speaking, several people who were proficient in the formation had already tried to use some of their own small means to try the forbidden formation of the Green Ox Tomb. However, after trying it, the faces of several people don't seem to look very good.

Mo Ao took out a fixed astrolabe, and before he could get close to the Qingniu Tomb, the pole yuan needle in the fixed astrolabe hissed and turned, and it was impossible to use at all. The white eyebrow also took out eight special subtle needle-shaped magic weapons, and inserted them into the bluestone on the ground, trying to escape into the magic circle of the Qingniu Tomb with this magic weapon, and used the technique of "Eight Poles to Fix the Star" to determine the direction of the array eye, who knew that the needle-shaped magic weapon could not be inserted into the bluestone on the ground at all, and could not even leave some traces on it.

No matter how hard the rock is, it is just a stone, and it is impossible to resist the power of the monk's magic weapon in the foundation building period, but the rock here is strange, and the magic weapon is difficult to move at all.

"White-eyed Daoist friends don't have to work in vain. The Qingyan within a radius of twenty zhang from this Qingniu Tomb has all been affected by the forbidden array in the Qingniu Tomb, and has become harder and stronger than steel.......

"I didn't expect that Baimei Daoist and this Mo Feng Daoist are actually formation masters, haha, I don't know if the two Daoists can see something?" The Xiuyuan master who was standing with Boss Hu suddenly laughed and asked Bai Mei Gong and Mo Ao. However, looking at the expression on his face, he looked quite disdainful, and seemed to be quite unimpressed by the two of them's trial methods.
