The fire of the demon soul obtained by the fusion of the corpse and soul of the Enma demon, after the refining of Ren Xiaoyao's Nine Beast Soul Fire Slash**, formed a transparent demon soul fire, which is very different from the previous beast soul fire.

Moreover, Ren Xiaoyao has a feeling that when this transparent demonic fire is cultivated to a high depth, it will no longer be isolated, but will completely turn itself into nothingness, and let its own entity become an empty body.

Moreover, with this shadowless slash, in the face of a crisis, Ren Yaoyao's escape probability has greatly increased.

In order to properly comprehend this shadowless slash, Ren Xiaoyao even took dozens of Meditation Enlightenment Pills mixed with wine, and practiced in the secret room of the Cave Sky Tower for half a year.

Half a year later, Ren Xiaoyao left the cave layer, and under the double concealment of the purple mirror and the double concealment of the shadowless escape, he secretly came to the bottom of the abyss, between the ninth and tenth layers, on the cliff of the bottomless abyss.

In the final analysis, the bottomless abyss is a huge pit, and the wall of the giant pit is also called the cliff, because it has been invaded by chaotic qi all the year round, countless caves and holes have been formed on it, and countless strange things and strange spirits have also been reproduced, and its danger is even worse than that of the Four Spirit Valley. Of course, the walls of the crater are also a great place to hunt for treasures.

The bottomless abyss has been blocked for so many years, and even though the danger is better than that of the Valley of the Four Spirits, the number of monks searching for treasures on the walls of the giant pit has gradually increased.

On this day, Ren Xiaoyao took Luo Feng to a certain place on the cliff, pointed to one of the ordinary caves on the cliff and asked, "This is where you call the location of the ore vein?"

Because the cliff is affected by the weathering of chaos all the year round, the rocks on the cliff show an extremely strange texture, and the wind blows through and there is a faint sound of ghosts crying and howling. Wherever Ren Xiaoyao pointed, there were hundreds of caves of different sizes, from which there was a thick black gas and evil wind blowing out, and some caves also heard the sound of evil spirits crying and howling.

Obviously, there is an unknown danger inside these caves.

"Yes, master, the cave through guò will lead you to the location of the vein. I was chased and killed by others, and when I fled here, I was exhausted, and I chose one of the caves to hide in the mind, but I didn't want to find an extremely hidden crack in the cave, and there was an extremely narrow passage in the crack, and I could reach the location of the ore vein by going about ten miles through the guò passage. Luo Feng said honestly.

With Luo Feng's current situation, he has no reason to lie in front of Ren Xiaoyao, and with his strength, he can't lie in front of Ren Xiaoyao. However, such a strange cave may still have some dangers that Luo Feng does not know, which has to make Ren Xiaoyao worried.

"What's the danger in the cave?" Ren Xiaoyao asked.

"This cave is very small, and I haven't found any living beings in it, but the chaotic aura in it seems to be much stronger than other places, and you need to take a few more Four Spirit Pills to enter it. Luo Feng replied.

Hearing Luo Feng say this, it seemed that there was no danger in it, and the ore veins that Luo Feng said were too attractive, Ren Xiaoyao hesitated slightly, and finally made up his mind to enter this cave.

"You go back and hide for a while, with your current strength, if you really encounter any danger, I may not be able to take care of you. Ren Xiaoyao said, stretched out his hand, and summoned Luo Feng back to the cave layer.

Then, Ren Xiaoyao summoned the golden battle king armor, put on the phantom clothes, and then cast the sixth slash of the Nine Beasts Soul Fire Slash, turning himself into nothingness, and then slowly sneaked into the cave.

Sure enough, the chaotic qi in the cave was much richer than outside, but for Ren Xiaoyao, who had already taken the Four Spirit Pills, these chaotic qi did not have much effect.

The whole cave just accommodates only one person, and the cave is full of gray-black mountain stones, which have long been weathered by the chaotic atmosphere for many years, and have already become extremely smooth and hard. These mountain stones were originally supposed to be just ordinary stones, but they have been affected by the chaotic qi for many years, and now they can be regarded as refining materials, and they can refine some spiritual weapons.

The drowsy chaotic aura blew out from the depths of the cave, blowing through the rocks inside the cave, making a sound similar to that of a ghost's howl.

Walking a hundred meters into the cave, according to Luo Feng's previous description, in a hidden place, Ren Yao removed a mountain stone embedded in the edge of the cave wall like a wedge, and found a crack three feet high and eight feet wide.

To get into this crevasse, you have to climb into it almost sideways like a crab. Ren Xiaoyao couldn't help but want to laugh when he thought that he was going to climb in like a crab, but there were no outsiders here, and Ren Xiaoyao didn't care, after blessing a few defensive talismans and light talismans on his body, his body floated horizontally and slowly crawled into the crack.

The rift was not dangerous except for the thick aura of chaos. Ren Xiaoyao followed the narrow passage behind the crack, passed dozens of bends, advanced for about ten miles, and came to a circular open land with a diameter of about 100 zhang.

The edge of the stone wall in this circular open field is inlaid with various mineral materials of various sizes, ranging in age from a few hundred to a thousand years. Some of the stone walls also have grooves and excavated marks, apparently mined by Luofeng before.

In addition, at the other corner of the stone wall, there is another small passage that leads to the depths of the cliff.

According to Shi Luofeng, since he discovered this vein, he has come here alone to mine more than a dozen times, like this kind of circular open land is what he mined, the deeper he goes, there are more than a dozen such circular open land. This circular open field was the first to be mined at the very edge, and the mineral materials in the vicinity were also the lowest.

Through the guò passage, Ren Xiaoyao advanced more than five miles again, and found another round open land where Luofeng had mined, and found that the quality of the mineral materials here was slightly better. However, mineral materials of this quality cannot enter the eyes of Ren Yao.

Then he advanced more than three miles, and Ren Xiaoyao found another round open field. After that, every mile away, there was a circular open field, which had been mined by Luofeng before.

It wasn't until the seventeenth circular open field that the last circular open land was finally mined at Luofeng. On the surrounding stone wall, the inlaid mineral materials are more than 10,000 years old, and the number is also significantly more than before.

However, this place is already the extreme depth of the bottomless abyss cliff, and the mountain stones on the stone wall are all purple and black, and its hardness is no longer inferior to the ordinary inferior magic weapon. Mining mineral materials here can be easily understood. There are a lot of raw Xuanhua crystal sand minerals on the stone wall, and the value is incalculable, but the Xuanhua crystal sand that Luo Feng sold to the Wushuang Treasure Building at the beginning was a little bit, just enough.

Facing this treasure mountain, Ren Xiaoyao couldn't help but feel a little difficult. Although these mineral materials are extremely valuable, they are also very difficult to mine, and Ren Xiaoyao is not willing to spend decades or even hundreds of years here as a miner.

In the middle of hesitation, Ren Xiaoyao suddenly had an idea, and his mind communicated with the cave heavenly layer and summoned the white tiger over.

The white tiger was originally evolved from the psychic treasure hunting rat swallowing the demon spirit bead, although it has been showing people in the form of a white tiger now, but its psychic treasure hunting rat's ability has not disappeared. At this time, with Ren Yaoyao's instructions, the white tiger once again changed back to the appearance of a psychic treasure hunting mouse, and as soon as it appeared, he immediately shook his spiritual nose and sniffed everywhere.

Suddenly, the treasure mouse's eyes flashed wildly, and he screamed a few times at Ren Xiaoyao with a "squeak" in his mouth, and then plunged into the stone wall and disappeared.

Seeing this situation, Ren Yao couldn't help but marvel at the mastery of the treasure hunting mouse's earth escape technique, and hurriedly blessed himself with a few superb earth escape charms and the best gold escape charms, and also followed the treasure hunting mouse into the stone wall.

With Ren Xiaoyao's current cultivation, he can use the Earth Escape Technique or the Golden Escape Technique to shuttle among the mountains and rocks, but the speed is very slow, far from being comparable to the treasure hunting mouse. In order to keep up with the speed of the treasure hunting mouse, Ren Xiaoyao also had to use spirit runes.

In this way, the psychic treasure hunting rat was in front, and Ren Yao was behind, quickly shuttling through the mountains and rocks.

The deeper he went, the more surprised Ren Yao became, the number of various mineral roughs whizzing past him was increasing, and the vintage was getting higher and higher. In the end, there were no mountain rocks, and there were dense rough stones of various minerals everywhere.

At this time, Ren Xiaoyao finally couldn't help but be ecstatic in his heart.

"The best vein, the absolute best vein!"

Like this kind of vein, there are all kinds of rare materials when you reach out and grab them, and they are old and pure, and they can almost be used directly like refining materials.

Moreover, what made Ren Xiaoyao even happier was that the psychic treasure hunting mouse seemed to look down on these superb mineral rough stones, and after discovering these superb mineral rough stones, his face showed a more anthropomorphic ecstasy and continued to drill deeper.

"Is there a treasure of greater value?" Ren Xiaoyao couldn't help but guess in his heart, looking at the earth escape talisman and gold escape talisman that had been consumed sharply on his body, Ren Xiaoyao couldn't care about feeling distressed, and directly slapped a few top-grade spirit talismans on his body.

Finally, after discovering the best ore vein, the psychic treasure hunting mouse took Ren Yao forward for more than a hundred miles, and suddenly there was no barrier from various mineral rough stones, and a huge and incomparably large hole appeared in front of him.

On the top of the big hole, there is a huge bell stone that is 100 zhang long hanging upside down, and the bell stone is wet and shining with a white halo, and drops of white liquid fall from the bell stone. At the bottom of the large cave under the bell stone, there is a lake with the same diameter of hundreds of zhang. In the lake, there is a white water, emitting a white light, illuminating the entire big hole in a hazy light, which can be seen but not really.

In the entire big cave, there was an incomparably rich aura, almost like a mist.

After the psychic treasure hunting rat came to this cave, he plunged directly into the white lake and drank wildly.

Looking at the prospect, Ren Xiaoyao's eyes widened, and he couldn't help but swallow his saliva, and his heart beat violently because of ecstasy.

Lingru, the legendary Lingru that contains endless spiritual power!

Looking at the quality of this spiritual ru, referring to the records in ancient books, Ren Xiaoyao can almost conclude that these spiritual rue are at least a thousand years old.

In other words, there is a lake full of thousand-year-old spirits!

According to ancient records, one drop of the thousand-year-old spirit can instantly replenish the mana in the body of the monk of Jiedan, and five drops can instantly replenish the mana in the body of the Yuanying monk. This lake full of spirits, Ren Xiaoyao will no longer have to worry about mana in the battle, whether it is a knot pill or a yuan infant or even a god in the future.

Moreover, another anti-heaven value of the thousand-year-old spirit ru is that it can be used as an alchemy material, greatly improving the quality of the elixir.

The value of this lake's thousand-year-old spirit is countless times more precious than the previous superb ore veins
