As soon as the three of them entered the underground black hole, a very cold yin qi came from the surface, and as soon as the mana in Lin Xin and Lin Xue's bodies worked, a faint spiritual defense film appeared on the skin of the two women, blocking the yin qi from the outside.

The yin qi in the Ten Thousand Ghost Cave is different from the yin qi in other places, it is with a trace of the yin qi of the Nine Ghost Realm.

If a monk's physical body is infected by this yin qi for a long time, it will cause the yang qi of life to weaken, and not only will his strength drop by three points in the future, but his cultivation qualifications will also decrease to a certain extent.

Contrary to the two women, Chu Xun felt that these yin qi were only good for his body, and there was no harm, allowing those yin qi to burrow into his skin.

Touch!

A powerful ghost that came out of the wall, which was equivalent to the triple practice of qi, was smashed by Lin Xin's palm.

Woo woo woo~

At this time, a gust of yin wind came from the depths of the cave, and Chu Xun and the three of them looked down, and it was dozens of black shadows rushing upwards outside, the faces of those black shadows were hideous and terrifying, constantly changing all kinds of grimaces, there were men, women, old people, children, and excited ghost cries came out of their mouths.

The aura on these ghost creatures is not strong, that is, it is equivalent to the appearance of one to three levels of qi training, if it is placed in the mortal world, it is an extremely fierce ghost.

And in front of Chu Xun, the three foundation building monks, they didn't even count the qualifications of ants, and the three of them didn't make a move, but just released the foundation building power on their bodies, and crushed the dozens of ghosts to pieces.

Since Chu Xun and the three of them released the power of Zhuji, the ghosts they encountered, feeling the breath on their bodies, all screamed and burrowed into the walls of the cave, and when the three of them went away, they carefully drilled out of the wall, feeling that there was no danger, and wandered around again.

In fact, Chu Xun also studied the walls around the cave and found that the hardness of the walls was comparable to the level of Dao weapons, and with his strength, he could only leave a shallow trace on it.

He buckled a piece of soil from the wall, found that this soil was no different from ordinary soil, and asked his two wives, only to know that this Ten Thousand Ghost Cave was a huge magic circle.

There was once a Jindan ancestor who thought that the existence of the Ten Thousand Ghost Cave would one day be a disaster for the cultivation of immortals in Beizhou, so he passionately several Jindan Ancestors tried to destroy the cave one by one, but found that a passage had just been destroyed, and after a while, the passage that was destroyed that day was restored to its original state.

"By the way, although the ghost creatures in this passage are all below the fourth level of Qi cultivation, there are hundreds of thousands of them, how did those Qi cultivation period cultivators pass through the passage and enter the world under the Ten Thousand Ghost Cave?"

Chu Xun opened his mouth and asked the two women.

You must know that although these low-level cultivators can't withstand the coercion of the foundation building monks, if they swarm in, even the Qi Cultivation Ninefold Cultivators will be instantly devoured by the yang qi and turned into a pile of white bones.

"That's because before they come in, they will buy ghost qi talismans from the Heavenly Ghost Gate, and they will exude ghost qi when they bring them on their bodies, and those ghost things will say that they will treat them as ghost things, and they will not attack. ”

Lin Xue spoke, her voice was like a ding dong of spring water, with a hint of ethereal, and an ethereal sound, like a heavenly sound.

Half an hour later, Chu Xun and the three of them passed through the underground passage and entered the underground world, it is said that this underground world was opened up by the powerful monks of the ghost world back then, and it was mixed between the human world and the nine ghost worlds, and it was somewhat similar to the independent small world of the secret realm.

Chu Xun, Lin Xue, and Lin Xin were all in this world under the Ten Thousand Ghost Cave for the first time, and their eyes looked around.

There is no light source in this underground world, but it is not the kind of darkness that you can't see your fingers, but a strange gray dimness, that is, you can see the distant scenery without your sense.

"What's that?"

Chu Xun asked, pointing to the sky in the distance.

It was a black sun like the sun, emitting hundreds of millions of cold black lights, and Chu Xun was shocked to find that those black lights were pure yin qi, as if the yin qi in the entire world below was provided by the black sun.

Lin Xin opened his mouth and said, "It is said that it is a supreme ghost weapon, which can draw a steady stream of yin qi from the Nine Ghost Realm and supply this underground world, and it is also the formation eye of the entire Ten Thousand Ghost Cave Underground World. ”

"Then why don't you destroy it, in that case, won't the underground world of the Ten Thousand Ghost Caves lose its yin qi and collapse and disappear on its own?"

Chu Xun wondered!

Lin Xin opened his mouth and said: "It is said that the size of the world under this is equivalent to one-fifth of the Beizhou Xiuxianli, if it collapses, the entire Beizhou Xiuxianli will collapse and sink to the bottom of the sea." ”

Lin Xin paused, and then spoke: "It is said that the great power of the Tribulation Period who was invited back then, after seeing the black sun, shook his head and said that the black sun could not be destroyed, so he sealed the Ten Thousand Ghosts Hall and forbade the high-level ghosts above the golden pill from walking out of the Ten Thousand Ghosts Palace. ”

"I think that the powerful monk of the Tribulation Period is not unable to destroy the Black Sun, but he is unwilling!"

Chu Xun said with great certainty:

"Are you saying that the Tribulation Period Power didn't want to destroy the Black Sun, and left it on purpose?"

Lin Xue, Lin Xin was a little incredulous, and the two women spoke at the same time: "If that powerful senior in the Tribulation Period is capable, then why doesn't he destroy the Black Sun?"

"Didn't you just say that if the world underneath collapses, the entire Beizhou Immortal Cultivation will collapse and sink to the bottom of the sea? ”

As soon as Chu Xun said this, Lin Xue and Lin Xin understood in an instant, and their eyes were different when they looked at him, it turned out that their husbands were not only terrifying in battle, but also looked at the problem so thoroughly.

This underworld has existed for more than 30,000 years, and the Beizhou Immortal Cultivation Realm has already drawn a map here.

Soon, Chu Xun identified the direction they were in according to the nearby mountains and rivers, and flew towards the tomb with the two girls.

Woo woo woo~

A moment later, a burst of ghost crying and howling came from the sky, and Chu Xun and the three of them looked up.

It was several black clouds that were hundreds of feet in size, and they were outflanking them at a very fast speed.

"Oh no! We've been spotted by the patrols. ”

Lin Xin and Lin Xue looked a little nervous, and instantly entered a state of preparation, and quickly spoke, explaining:

"The patrol ghost soldiers are composed of ghost generals in the foundation building period, and tens of thousands of ghost soldiers equivalent to more than seven levels of qi training, specializing in hunting and killing the foundation building monks who came in from the Beizhou Xiuxian, and that black cloud is a patrol ghost soldier legion, and it is also a ghost formation, which is comparable to the Great Perfection monks in the later stage of foundation building. ”

"However, the ghost qi talisman made by the Heavenly Ghost Gate can only cover up the yang energy on the body of the Qi cultivation period monks, and cannot cover up the existence above the foundation building period, so usually, there are very few foundation building monks in the underground world of the Ten Thousand Ghost Caves, and those who come down are all Qi cultivation period monks who come in to subdue the ghost slaves, or look for genius earth treasures. ”

At this moment, the three of them were surrounded by several teams of patrolling ghost soldiers who were equivalent to the Great Perfection of the Foundation, and the palms of Lin Xue and Lin Xin were in cold sweat.

In each black cloud, there were ten ghost generals, nine thousand nine hundred and ninety ghost soldiers, exactly ten thousand.

Among the ten ghost generals, there is one equivalent to the middle stage of foundation building, the middle stage of the ghost general. Nine early monks who built the foundation, early ghost generals.

There are a total of eight black clouds, surrounding Chu Xun and the three of them, and if you calculate carefully, it is equivalent to eighty foundation building monks, and nearly eighty thousand late-stage Qi cultivation monks.

Kill, kill, kill!

Suddenly, the roar of a demon came from the black clouds, and immediately, hundreds of pitch-black arrows were shot out of the eight black clouds!
