Just when Lin Xiao was sitting in Tianyun City, in the Netherworld Cave of Wusun Kingdom, Huang Sheng began a new round of exploration of the Netherworld Cave, which was originally discovered by the Sun family of Wusun Kingdom and had been hidden in the snow for hundreds of years.

It's not that the Sun family doesn't know the value of the Netherworld Cave, it's that their strength is not capable of developing at all, even if the Sun family's Daogang cultivator goes down, they can't go far, and the price of refining the Nine Shadows True Water is extremely high.

If it weren't for the rebellion of the beast tide at the beginning, the Sun family would not have had the idea of fighting the Netherworld Cave at all, and after the Battle of Annan, the Netherworld Cave was leased to the Heavenly Saint Sect, at first it was sixty years, but then it continued to increase, and now the contract signed is five hundred years.

The Sun family took this opportunity to get great benefits, especially the Lingming Pill, Lin Xiao took the Lingming Pill as a lure, the Sun family could not refuse, for more than two hundred years, the Sun family got a total of five Lingming Pills, and three of them broke through the Lingguang Period, and the strength of the Sun family has all recovered, and it is better than the Wu family.

The Heavenly Saint Sect also refined tens of thousands of catties of Nine Shades True Water in the Nether Cave before and after, and he consumed most of it, and he could sell it in large quantities, making a lot of profits.

Since Huang Sheng entered the Netherworld Cave, the rest of the Lingguang monks of the Heavenly Saint Sect have not come in, it can be said that the Netherworld Cave is monopolized by Huang Sheng alone, for this reason, Huang Sheng has to provide the sect with one hundred catties of Nine Shadows True Water every year, this number is not difficult for Huang Sheng in the Divine Void Period, it only takes three months a year to refine, and the rest of the time is either practicing or exploring the Netherworld Cave.

After decades of exploration, Huang Sheng entered the underground of the Netherworld Cave for tens of thousands of meters, the Netherworld Cave is a huge underground space, and it overlaps and intertwines with the space cracks, it does not seem to belong to the world of the Immortal Cultivation Realm, but it is like an ancient battlefield in the depths of the desert, because the space is broken, so a unique space is formed.

Huang Sheng chose a spatial crack to enter, and after entering, she found that this was an incomparably vast world, and her divine sense was stretched to the extreme, and she did not find the end.

"The consciousness is broken, and something swallows it up"

Suddenly, Huang Shang's soul moved, and the divine consciousness she extended out suddenly disappeared, Huang Shang's body moved, and she moved in that direction, traveling hundreds of miles, and Huang Sheng actually heard the sound of running water.

"This is the river, so heavy yin"

Huang Shang came to a river, the river was hundreds of meters wide, there were no plants on the riverside, it was bare, the river water was black, and the yin qi coming from the river surface made her feel shocked.

For the Netherworld, they are not without speculation, what they expect is that the Netherworld Cave is directly connected to the Netherworld, whether it is the real Netherworld or the fake Netherworld, it is difficult to say.

In the world of cultivating immortals, there is a distinction between true and false, the real underworld is the legendary hell, which is an extremely mysterious place, no one has ever been to, and the fake underworld is a netherworld place that appears for various reasons, and there are many places.

"Could it be that this is a fake netherworld, the yin qi of this river is too heavy, and there is definitely a negative spiritual vein at the bottom of the river, if this is discovered, it will definitely be a great achievement."

Huang Sheng thought that the most important thing in the Netherworld is the negative spiritual vein, which is the same as the spiritual vein on the earth, although the monk cannot use the negative spiritual vein to cultivate, but the production above is extremely rare in the immortal cultivation world.

Huang Shang walked all the way up along the underground river, traveled dozens of miles, Huang Shang picked up the river water, sniffed it on his nose, and was immediately overjoyed, in the yin qi of the river here, it is enough to refine the Xuanyin heavy water, this Xuanyin heavy water is also a kind of special spiritual water, which can be used for some special things, and people who don't need it naturally feel worthless, but those who need it are worth a thousand gold.

"What people"

Suddenly, Huang Sheng burst into a shout, her divine consciousness skyrocketed, and in her divine consciousness, two figures floated over.

"Blood, blood, blood"

"Spiritual Light Level Ghost Cultivator"

Huang Sheng was shocked, the person who came to her was not a living person, it turned out to be a ghost monk, which made Huang Sheng a little shocked, there was a ghost monk in this place.

"Boom, boom"

Huang Shang didn't say a word, he started directly, the two spiritual light level ghost cultivators were not Huang Shang's opponents at all, one was killed by Huang Sheng in a few rounds, and the other ran away directly, and Huang Sheng didn't chase after him.

The fallen ghost cultivator's yin qi disappeared, leaving behind a soul crystal, which is where the essence of the ghost cultivator's body is, Huang Sheng took the soul crystal and retreated directly, but what Huang Shang didn't know was that not long after she left, several figures appeared in her previous position, and the figures of these people were extremely solid, not weaker than the living.

"I smell the smell of blood"

"It is indeed a living man, and he has not tasted blood for many years, many years"

"I don't want blood, I want the soul of a living person, that taste is really nostalgic"

"Let's go, go back and prepare, they'll come again"

········

"Ghost path monk, is it a living person who practices the ghost path or the soul body ghost path?"

In Tianyun City, Lin Xiao received the news from the night owl, and couldn't help asking, there are two kinds of ghost paths, one is the cultivation of living people, turning themselves into people and ghosts, it is one of the evil demons, and the other is the ghost cultivation of practicing ghost dao exercises with the soul body after death, and it is said that the highest can also be practiced to the realm of ghosts and immortals.

"Back to the master, Huang Laozu sent a message that it was the Soul Body Ghost Dao, she killed a fifth-order ghost cultivator equivalent to the spiritual light period, there is a soul crystal left, and it is on the way to be sent, and it is expected to arrive in two days."

"I understand, spread Ye Nanyu, let him send someone over first, I will come over after a while, I won't go, they are not allowed to act privately"

"Yes, Master"

The night owl disciple left, and two days later, Lin Xiao got the soul crystal and played with it in his hand.

Soul crystals have a lot of functions for monks, and high-level puppets must have soul crystals to refine, so as to ensure that the puppets have a certain spirituality, and monks can operate flexibly.

And the soul crystal also has an extremely important influence on the magic weapon, the difference between the magic weapon and the magic weapon is to see if there is spirituality, if the magic weapon wants to let the monk use the vitality to nourish, don't think about it for thousands of years, so like the magic weapons of the major sects, all of them are cultivated by generations, which is extremely rare.

But if there is a high-level soul crystal integrated into it, it can greatly shorten this time, and even directly refine the magic weapon, which also makes the soul crystal extremely valuable, and this fifth-order soul crystal is worth at least hundreds of thousands of Xuan crystals.

There are very few soul crystals in the immortal cultivation world, because this thing is only available to ghost cultivators, and most of the areas in the immortal cultivation realm are not suitable for ghost cultivation life and cultivation, and they can only be achieved in a specific environment.

It took Lin Xiao a few days to deal with the affairs of Tianyun City, and handed over the matter to someone to deal with, and he came to Wusun Country secretly.

At this time, Ye Nanyu, Iron Lion, Huang Sheng and others were all there, as well as some night owls, within a radius of ten miles from the Netherworld Cave, it had already become the territory of the Heavenly Saint Sect, and even the Sun family had no power to touch it.

"I've seen the boss"

"Have you gone down?"

"No, they are all waiting for the order of the master"

"Huang Shang, tell me, what's the situation below?"

"Yes, the master, the Netherworld Cave goes down to about 10,000 meters, there will be a large area of underground space, go a hundred miles to the northwest, there will be a chaotic space, there are many space cracks in it, self-contained, I have explored more than 20 space cracks, all of them are small worlds, the small ones are only a few hundred meters in size, I found that this ghost cultivation is a big world, how big I don't know, I searched for hundreds of miles, it is estimated that it is still the tip of the iceberg, there is a Yin Water River in it, the Yin Qi is extremely heavy, and the Xuanyin Heavy Water can be refined, and then the ghost Xiu wanted to sneak attack me, and I found it in advance, I felt that there were more than one or two ghost cultivators, so I withdrew, and I didn't dare to act rashly”

"Xuanyin heavy water, it seems that this Netherworld Cave still has great development value"

"So to speak, but the underground yin qi is too heavy, not suitable for low-level disciples, I estimate that at worst, it will take the spiritual light period to not be affected, otherwise the yin qi may hurt the disciple's foundation."

"I see, let's go, go down and see"

Lin Xiao nodded, Huang Sheng said that it was not as good as going to see it in person, Lin Xiao and the four of them went down, and the rest were guarding on the ground.

Iron Lion has also broken through the Divine Void Period at this time, and he has just been out of the customs for a few years, but he is the weakest of the four, if it weren't for his relationship with Huang Shang, Lin Xiao would not let him down.

The four of them were not disturbed by the Yin Qi, and came directly to the underground of the Netherworld Cave, where the Yin Qi was extremely heavy, and it was easier to refine the Nine Shadows True Water.

"Yin Qi and Demon Qi belong to the same sect and different origins, the Demon Qi of Demon Cultivation..."

On the way, Huang Sheng was also explaining to Lin Xiao the difference between ghost cultivation and demon cultivation, demon qi is a kind of energy fused with yin qi and xuan qi, which is more complicated, while yin qi is much purer, and it is the opposite of xuan qi, yin qi and demon qi both belong to the dark type of energy, which is regarded as the same sect.

Lin Xiao naturally knew these theories, and Lin Xiao didn't stop them, and the four of them entered the spatial crack that Huang Sheng said, and there was a small world inside.

This kind of small world is somewhat similar to the secret realm, and it is also independent of the outside world, but the secret realm is artificially created and can be controlled by monks, and these small worlds are the kind that monks cannot control.

As soon as the four of them entered, they found traces of ghost cultivators, and those ghost cultivators also found Lin Xiao and others, Ye Nanyu took the lead in rushing over and grabbed one of them.

"Master, I have seen his memory with the God Search Spell, it is very confusing, but basically I have found it clear, this is indeed a fake netherworld, the area is extremely vast, the memory of this ghost cultivator is not less than thousands of miles, and there are many ghost cultivators in his memory, I am afraid we have entered the ghost country"

"I know, they're coming"

Lin Xiao nodded, Lin Xiao's divine sense was much stronger than theirs, and he had already discovered the traces of the other party, and there were a large number of ghost cultivators advancing, led by a seventh-order ghost cultivator, which was enough to be called a ghost king.

"There are a lot of ghost cultivators, no less than three thousand"

Soon, Ye Nanyu also found out, and immediately exclaimed, he couldn't understand how there could be so many ghost cultivators in this kind of place.

"Attack, defeat them, catch a few high-level live mouths, and see what is going on here"

Lin Xiao nodded, and then took the initiative to attack and went towards the ghost cultivator, Lin Xiao wanted to see what the situation was here.
