Although there were no half-ancestor monks in the Heavenly Pole Valley, they occupied a separate star field alone. Although this star field is not large, it is quite full of aura.

It stands to reason that such a resource-rich land could fall into the hands of the Heavenly Pole Valley.

But this has to start with the royal family of the Yin Luo clan.

Although the Yin Luo clan is the same as the human race, the distribution of power is composed of many families, sects, and scattered cultivators. But unlike the human race, there is a royal family in the Yin Luo clan.

The royal family does not refer to a certain noble bloodline of the Yin Luo clan, in fact, it is also a force, a force built by recruiting countless powerful people of the Yin Luo clan.

The meaning of the existence of the royal family is to suppress the various forces of all sizes in the Yin Luo clan, so that the Yin Luo clan will not have a large-scale monk war, and with a wide range of territorial competition, even the monks of the half-ancestor realm will not be allowed to make a move at will.

For example, the reason why the Tianyin Hall of the Blood Bat Clan was qualified to control the Fire Desert together with the Emperor Extreme Sect was that the ancestor of the Emperor Extreme Sect was evil, and he couldn't act at will.

With the existence of the royal family, the entire Yin Luo clan can develop in a good direction, and its strength will become stronger and stronger. It is the current Yin Luo clan, which is definitely a veritable powerful race.

In fact, it is not only the Yin Luo clan, but also other strong clans.

Even the demon clans adjacent to the human race have an organization similar to the Yin Luo royal clan such as the Ten Thousand Demon Palace.

It is worth mentioning that the reason why Hong Ying was co-opted by the Sky Fox Holy Maiden to deal with Dongfang Mo was that the Sky Fox Holy Maiden promised this woman a condition, that is, after Red Sakura cultivated to break through to the Breaking Dao Realm, she would be given a place to enter the Ten Thousand Demon Palace.

Only the Terrans, each force is in its own position, even if there are demons and underworlds on the left and right, but every once in a while, a civil war breaks out within the Terrans. I'm afraid that the reason why the human race is weak also has something to do with this.

Interestingly, the half-ancestor realm cultivators in the human race also have their own agreement, that is, after cultivating to reach the half-ancestor, they cannot meddle in sect disputes or interfere in the development of other forces. And this, they call "rules".

Back then, Dongfang Yu personally appeared in the Low Law Star Domain, and the old man who rode a bull prevented Dongfang Mo from killing Bu Zhenren, which was against the rules.

And with the existence of the Yin Luo Clan's royal family, a force like Tianji Valley that can occupy a star field alone is actually not a small number among the Yin Luo Clan. As long as there is no half-ancestor realm cultivator to make a move, other forces want to fight against Tianji Valley to compete for cultivation resources, and they must also weigh their own weight.

Tianyin Cave is in the extreme north of this star field occupied by Tianji Valley. There is no sunlight all year round, and it is damp and dark, and even the aura that fills it is extremely cold.

It is said that in the extreme north of this star field, there was a tragic battle between the monks of the Demi-Ancestor Realm, and more than one or two Demi-Ancestors participated in it. It is said that two demi-ancestors fell here, and those two demi-ancestors were the bodies of yin spirits, and after their deaths, they formed a land of extreme yin here.

As long as the land of extreme yin is formed, it will be like a whirlpool, constantly attracting the power of yin and cold. In the end, in this land of extreme yin, there was the birth of the Xuansha extreme yin.

As a result, this Tianyin Cave has also become an important secret realm in Tianji Valley.

The entrance of Tianyin Cave is on a cliff wall with a length and width of about 1,000 zhang, and the black and swarthy entrance of the cave is oval.

Plumes of thick black smoke continued to be spewed out from it, which looked a little eerie.

And these black smoke are a kind of yin qi that has the effect of eroding mana and physical body.

Although these Yin Qi are not as violent as the evil qi in the Ancient Evil Land, if someone stays in it all year round, it will inevitably be greatly affected.

And as it goes deeper, the yin qi will become more and more intense, and the effect of erosion will also increase exponentially.

For example, in a place where the Xuan Sha Extreme Yin can be born, the intensity of its Yin Qi is so strong that even if a Dao Breaking Realm monk does not have the exercises or magic weapons to restrain this thing, I am afraid it will be difficult to get close.

At this time, Dongfang Mo and Han Ling's figure appeared in front of the entrance of the Tianyin Palace, standing in the air beyond the cliff.

Looking at the huge hole in front of them, which was constantly spitting out yin qi and was more than a hundred zhang in size, the two glanced at each other, then nodded, and their bodies disappeared into it.

At the moment when he was swallowed by the yin qi, Dongfang Mo suddenly felt a faint sense of coldness, but even if he didn't stir up his mana, there was nothing wrong with this coldness. In his opinion, even Ning Dan Monk could easily resist it.

Immediately, he swept towards it with Han Ling.

As the two of them went deeper, they sensed that the coldness of the Tianyin Cave was gradually improving.

But all this was as they expected, and the two of them were not surprised in the slightest, but continued to go deeper without slowing down the slightest.

The structure of the Tianyin Cave is very distinctive, and after extending for about a thousand zhang in front of the cliff, it will change sharply in one direction and go deeper into the ground.

And all the way to the underground, after going deep into 100,000 zhang, you will see a cold swampy land.

That swampy land is the place where the Xuan Sha Ji Yin can really be born.

The area of this place is extremely vast, and the divine sense is greatly limited, even the scope that Tianji Valley has explored over the years has not covered the swamp land, and there are still many places that cannot be explored.

Therefore, if Dongfang Mo and the others want to find the Xuansha Extreme Yin, they must go to the depths.

In the Tianyin Palace, the most dangerous thing is that in addition to the deeper and deeper, the more cold the yin qi becomes, there are also many yin spirits born in the depths.

As soon as he thought of the Yin Spirit, Dongfang Mo remembered the Blood Clan Bone Mountain back then, as well as the Land of the Ghost Mound, which also gave birth to such a thing as the Yin Spirit because of a lot of evil qi.

It's just that the Yin Spirit on the Bone Mountain back then, the cultivation level was the foundation building period, even if it was the land of the Ghost Mound, the Yin Spirit with the highest cultivation was only the Ning Dan Realm. But the yin spirit in the Tianyin Cave is very different.

Because this place is a high law star field, there is no suppression of the power of the law, and the yin qi is extremely abundant, it is said that countless years ago, there were also Yin spirits in the realm of Guiyi in this place. Some people speculated that the Yin Spirit was the soul of a half-ancestor who had died at the beginning, but it was later besieged and killed by several Returning Realm monks in the Heavenly Pole Valley at the same time.

Since there has been a Unified Realm Yin Spirit appearing, then the Dao Breaking Realm Yin Spirit naturally also exists, but this kind of Yin Spirit is still very rare, at least in the past hundred years, the Heavenly Pole Valley cultivator who stepped into the Tianyin Cave has not seen it.

In addition to the Yin Spirit, there is also a Yin Snake that feeds on Yin Qi in the swamp. Although the strength of this kind of Yin Snake is not strong, they have a strange magical power, that is, the teeth are extremely sharp, and they can rush up like a ghost from the swamp below as fast as lightning, and easily pierce the monk's body protection qi.

If they were bitten, with the strong poison of these Yin Snakes, those who cultivated below the Divine Journey Realm would definitely die.

In addition, it should be noted that there is a monk of the Heavenly Pole Valley in the Tianyin Cave.

Although Tianji Valley has clear regulations that private fights are strictly prohibited in the sect, in the Tianyin Cave, if you encounter an enemy or someone who wants to make money, it is also very common for people to die.

Not to mention Tianji Valley, this is not uncommon in any place.

As long as there is no big movement, Tianji Valley will also turn a blind eye, because this may also stimulate the strength and fighting spirit of these disciples.

Whether it was the Yin Spirit or the Yin Snake, or the monks of the Heavenly Pole Valley, it didn't seem to be a big threat to Dongfang Mo and Han Ling. Even if they encountered a Dao Breaking Realm cultivator, the two of them were not afraid.

At a certain moment, the two of them swept down at an extremely fast speed, and finally came to the bottom of the ground at a depth of 100,000 zhang.

As soon as they swept their senses, they found that the ground under their feet was a swamp of mud mixed with a kind of turbid black water, and from time to time they could hear the sound of gurgling, bubbles bubbling and bursting. At the same time, you can smell a faint fishy smell here, which is unique to the swamp.

After arriving here, the two of them froze, and then their divine consciousness probed from the center of their eyebrows.

Although the Yin Qi will greatly hinder the Divine Sense, the Yin Qi in this place is not too thick, and with the cultivation of the two of them, it is still very easy to cover the radius.

And in the shrouded divine consciousness of the two, they soon found that there were three stone pillars that stood up thousands of zhang away, dozens of zhang high.

These three stone pillars were deliberately set up here in the Heavenly Pole Valley in order to be able to identify the direction.

After observing the order and direction of the three stone pillars, the two of them moved and swept in a certain direction.

Dongfang Mo and the others have a very clear purpose, and this trip goes directly to the depths of the southwest of this swampy land, where the yin qi is the thickest, so the probability of the birth of Xuansha Extreme Yin is also the greatest.

After about half a day passed, Dongfang Mo's divine sense was greatly limited, and at this time, they could only cover the distance of five thousand zhang in a radius

"Whew!"

At a certain moment, suddenly a sound of breaking the air sounded.

A black arrow rushed out of the yin qi in front of him like lightning.

As soon as Fang appeared, this black arrow was like a spiritual intelligence, and it suddenly froze, as if it didn't expect to meet Dongfang Mo and the others, but in the next breath, it still shot towards the nearest Dongfang Mo eyebrows.

"Buzz!"

Dongfang Mo's body erupted with a repulsive force, and the next moment, this black arrow was blocked by an invisible force, unable to move.

Only then did he see that it was a black snake with a length of feet and the thickness of a finger.

The black snake had a ball of flesh the size of a fingernail on the top of its head, and its sharp mouth opened at this time, revealing two sharp fangs. After being confined outside Zhangxu, he also spit out a snake letter and made a "hissing" sound.

Dongfang Mo didn't expect to encounter the Yin Snake so soon, which surprised him.

The next moment, he still stretched out his hand and took a picture of the object.

With a "whoosh", this black yin snake was suddenly captured by him in the air, and then it was wrapped in a layer of mana condensed qi, and looked at it in front of him.

And after this beast was imprisoned, it actually rampaged in the gang qi, making a thumping sound, trying to open the gang qi's confinement.

It's just that the strength of this yin snake is really too low, so naturally it can't break free from Dongfang Mo's palm.

"Huh!"

Just when Dongfang Mo looked at the Yin Snake that was rushing in his anger with interest, another sound of breaking wind sounded. Then a young man dressed in the costume of Tianji Valley swept out of the yin qi in front of him.

As soon as Fang appeared, the young man's figure also paused suddenly, and then looked at Dongfang Mo and Han Ling in disbelief, obviously he didn't expect that there would be two people silently blocking the front.

And when he saw the Yin Snake that was caught in the palm of Dongfang Mo's palm and couldn't move, the young man's expression couldn't help but change.
