The Great War of the Four Clans finally ended, and all the tribes withdrew their troops from the front line, returned to their own territories, and began post-war reconstruction work. Even the Terran territories occupied by the three demon clans in the Great War were returned to the Terrans one by one. Under the leadership of the Sage King, the Terrans relocated the mortals from other parts of the Terrans to the previously occupied areas, and began a new round of multiplication. The other three tribes are doing similar work.

After decades of war between the four clans, the creatures in the four realms have decreased dramatically, the pressure on the entire interface has decreased sharply, and the aura of the four clans in the air has become stronger than before. Moreover, because of the decrease in living beings, the resources have become relatively more, and now the cultivation has become a little easier than before.

This is the essence of the battle between the four clans of the Four Realms: when the number of living beings exceeds the limit of the interface, in order to prevent the interface from collapsing, the battle of the four clans can only be used to reduce the number of living beings and give the remaining living beings a chance to survive.

Now, the war between the four clans is over, and the merchant alliance is the first to resume exchanges and trade materials with each other. In a few decades, when the resentment between them has subsided, the monks will have more communication with each other.

However, most of the real resentment existed among the low-ranking monks, and at most spread to the monks of the Edan Sect. Some of the high-level cultivators of the four clans have experienced many wars of the four clans, and they don't have much feeling about this war.

Under the joint initiative of the kings of the four clans, the Yuanying monks of the four clans held many large-scale trade fairs in just one year after the war. Through these fairs, the four clans collected a large number of rare materials, all of which were used to refine the Ancient Teleportation Array.

At this time, the monks of the four clans and some of the monks of the middle stage of the Yuan Infant all entered a state of retreat to prepare for the trip to the Nuwa realm in the near future.

The trip to the Nuwa Realm is not only related to whether the few missing materials in the Ancient Teleportation Array can be collected, but also whether the monks of the late Yuan Infant can find a way to advance into gods. In the eyes of these Yuan Infant monks, especially the late Yuan Infant monks, the advanced transformation of the gods is the most important, and the other qiē are floating clouds.

However, the four clans, including the human race, did not know that in an extremely hidden place of the ghost race, there was a very huge superb yin vein. In the depths of this very huge land of the best Yin veins, there are nearly 50,000 Terran monks in the Yudan period, that is, the Xiaoyao people of Ren Yao, the Imperial Ghost Hall of the Xiaoyao Sect.

After Ren Xiaoyao secretly sneaked into the territory of the ghost clan, he directly dived to the place of the best yin vein, but found that the ghost qi outside the best yin vein was already comparable to the outside world, and it was extremely weak.

After going all the way to the depths of the best yin vein, he found the people of the Imperial Ghost Hall of the Loose Sect who were cultivating frantically.

The depths of the best yin vein are like an underground world, the deeper you go, the richer the ghost qi becomes, the higher the level of the ghost thing, and the stronger the strength. Instructed by Ren Xiaoyao, the Imperial Ghost Hall slowly penetrated from the outside of the best Yin vein to the inside, eating away at the ghost qi in the best Yin vein little by little, and subduing the ghost things in the best Yin vein one by one.

Moreover, at the beginning, Ren Xiaoyao had warned the Xiaoyao people in the Imperial Ghost Hall that they were not allowed to participate in the war unless the human race was in danger of life and death. As a result, these people from the Imperial Ghost Hall have been staying in this superb yin vein for cultivation all along.

Up to now, most of the Xiaoyao people have advanced to the stage of knotting, and many of them have formed pills on their own without knotting Jindan. The remaining few foundation-building monks have also reached the great consummation of the late stage of foundation building, and they are only one step away from Jiedan. Moreover, Ren Xiaoyao, who had condensed the Yuan Infant, was more proficient in the use of the White Snow Ring, and after further purifying the bloodlines of these Great Perfection Xiaoyao clansmen in the late stage of foundation building, it was only a matter of time before they advanced to the Yudan Period.

Seeing Ren Xiaoyao's arrival, everyone in the Imperial Ghost Hall was extremely excited, and seeing that Ren Xiaoyao had advanced to the Yuan Infant Stage, everyone in the Imperial Ghost Hall was even happier.

For the Xiaoyao people in the Imperial Ghost Palace, Ren Xiaoyao was not stingy, each person gave a hundred drops of thousand-year-old spirit milk, and selected a large number of top-grade refining materials from the crystal refining layer to give to everyone, enough for each person to refine a ghost magic weapon. Moreover, Ren Xiaoyao also opened the altar to preach the Fa, and explained his comprehension of the Dao Law, especially the comprehension of the Nine Beast Soul Fire Slashing Technique, to the people in the Imperial Ghost Palace.

All the people in the Imperial Ghost Hall are Xiaoyao people who have the bloodline of Ren Xiaoyao, and they can perform the law of Xiaoyao, and all the exercises performed by the law of Xiaoyao are Ren Xiaoyao's exercises, among which the Nine Beast Soul Fire Slash is the main. Ren Xiaoyao's comprehension of the Dao Law and even the comprehension of the Nine Beast Soul Fire Slashing Technique was very helpful for them to comprehend the supernatural powers in the Freedom of Nature.

Since the war between the four clans has ended, and the outside does not know the existence of the Imperial Ghost Palace, Ren Xiaoyao simply hides the Imperial Ghost Palace deeper and cultivates it as his own personal soldier. Since it is a private soldier, Ren Xiaoyao has to train it to be his killer weapon, or if he doesn't take it out, he has to deter the four clans.

After teaching the Dao method to the Imperial Ghost Hall for half a month in a row, Ren Xiaoyao left the Imperial Ghost Hall in place to continue cultivating, while he entered the depths of the best Yin Vein.

The deeper the best yin vein, the stronger the ghost qi becomes, and before Ren Xiaoyao was only in the knot stage, his strength was not enough, and he could not deeply explore the best yin vein. Now that he has been promoted to the Yuan Infant Stage, it is natural to take a good look.

Moreover, the best Yin vein is hidden in the ground for hundreds of miles, and there is no trace of it from the surface, as if a natural magic circle has been formed on the surface to hide the best Yin vein. This point seems to be in the best yin vein of artificial signs, which makes Ren Xiaoyao care very much.

After escaping into the depths of the best yin veins for hundreds of miles, there is still no bottom, but the richness of the ghost qi has increased more than a hundred times. The rich ghostly aura floated in the air like a black cloud, reaching out to touch it, like a texture. But the entire underground was pitch black everywhere, and the sight was no longer useful, so I could only use my mind to investigate.

One by one, the ghost kings with different appearances are cultivating in their respective territories, and they do not invade each other, just like another ghost clan's land. These ghost kings, all of whom have reached the stage of cultivating to form a pill, have condensed the ghost pill, and have evolved a complete spiritual wisdom.

Ren Yao, who performed the shadowless slash, was like an invisible god of death, passing through the territory of the ghost kings one by one, and secretly ingested the ghost kings of the Dan period into the Hundred Ghost Drill Diagram for the Ghost King in the Hundred Ghost Drill Diagram to devour. Moreover, wherever Ren Xiaoyao passed, as long as there were some valuable ghost clan materials, they were all included in the storage bag by Ren Xiaoyao.

This is already the depths of the best yin vein, there are a large number of ghost kings in the Dan period, and the higher the cultivation of the ghost king, maybe there will be a ghost king in the Yuan infant stage, Ren Xiaoyao doesn't want everyone in the Imperial Ghost Hall to come here to risk in vain, so this task of collecting treasures is completed by himself.

Soon, Ren Xiaoyao secretly captured hundreds of ghost kings in the Yudan period into his own Hundred Ghost Drill Diagram. The thirty-six mutated ghost kings in the Hundred Ghost Drill Diagram were already on the verge of promotion after devouring hundreds of ghost kings in the Yudan stage. At this time, Ren Xiaoyao had to stop continuing to capture the ghost king, and instead dived into the depths of the best yin veins alone.

However, as Ren Xiaoyao continued to advance into the depths, he did not find the Yuan Infant Ghost King, and the number of Ghost Kings connected to the Dan Stage was getting smaller and smaller. In the environment, the ghost qi became less and less, and another unique and strange aura slowly increased, eroding and devouring other qiē powers.

"What kind of breath is this, it is a hundred times more powerful than death qi!" Ren Xiaoyao was shocked in his heart, and urged the mana in his body with all his strength, forming a defensive shield on the surface of his body, so as to resist this strange aura.

However, this strange aura was devouring Ren Xiaoyao's mana at an extremely fast speed, even if Ren Xiaoyao's body had enough mana, he had to take a few drops of thousand-year-old spirit milk every half an hour to replenish his mana.

"Hey, the Immortal Stone!" Continuing to move forward for dozens of miles, Ren Xiaoyao suddenly found that there were some small and small Immortal Stones scattered on the ground, and that strange aura emanated from this Immortal Stone.

Ren Xiaoyao turned into a hand, grabbed one of the spirit stones and looked at it carefully, with doubts on his face: "Although these stones look like spirit stones, they emit not dead air, but another kind of aura that is more powerful than dead air. Could it be that these stones are not dark stones, but something more powerful than the dark stones? ”

"Could this be the real Netherstone These weird breaths can't be the legendary Netherworld unique Netherworld Qi, right?" Ren Xiaoyao looked at the stone in his hand that resembled the Netherstone in his hand, and his heart was shocked again.

When Ren Xiaoyao was still a Qi refining cultivator, he had found some stones similar to the Immortal Stone in the Qingyun Space, which exuded a strong dead aura. Later, with the richness of Ren Xiaoyao's experience, he did not think that the stones he once found were the Immortal Stones, but the stones he saw now were more like the Immortal Stones.

It's just that in the legend, the Underworld Stone is also known as the Netherstone Stone, but it is a unique stone in the underworld.

Is this the underworld, or the way to the underworld?

For a while, Ren Xiaoyao felt a little jealous, and there was some hesitation in his heart about whether to continue to move forward.

The underworld is a place where only the undead can go, and if Ren Yao is now a living person, if he dares to move forward, he may be killing himself.

"Anyway, let's collect some real Nether Stones first. Ren Xiaoyao thought about it, and after all, he couldn't help but put the pieces of Netherstone on the ground into the Blue Yin Pool.

The Netherworld aura emitted by the Netherstone was too domineering and too dangerous, and Ren Xiaoyao didn't dare to casually put it in the cave layer. There is a large amount of Kuiyin heavy water at the bottom of the Biyin Pond, which can be used to place these Netherworld Stones.

While collecting the Nether Stone, Ren Yao moved forward cautiously.

After advancing for dozens of miles, Ren Yao had collected tens of thousands of Netherstone stones. Moreover, the deeper you go, the more and more the Netherstone number and volume, and the more intense the Netherworld Qi emitted. Even in the end, almost every time a pillar of incense passed, Ren Xiaoyao had to take a hundred drops of thousand-year-old spiritual milk to replenish the mana consumed extremely quickly.

Suddenly, Ren Xiaoyao, who was slowly picking up the Netherstone Stone, heard the sound of running water in front of him and was taken aback again
