After a soft snort, Xu Yu, who was happy, found himself standing firmly in a quiet void.

Almost at the same time, a familiar thought came to his mind.

"The intensity of the aura is appropriate, the reserve of third-class aura 9, can be fused with fourth-grade aura 1, no energy consumption, is it fusion?"

As soon as this idea appeared, Xu Yu became ecstatic again, fourth-class aura!

In this super cave mansion, he really has the capital that can allow him to fuse fourth-class aura, and when he looks at it, all he can see is a space filled with second-class aura.

This space is limited, it is not a forbidden space, but a real cave, and when he releases his divine thoughts, he will envelop the entire cave, but its size is about the same as the urban area of Linzhou, it is a flat valley, although it is underground, but it is also sunny, plus the river surrounds, it looks like it is peaceful and beautiful to the extreme.

Especially when all of this is bred under the second-class aura, it brings out a layer of psychedelic luster, even the verdant grass growing in the valley and rivers exudes amazing spiritual power fluctuations.

Xu Yu even sensed the breath of life in those rivers, which were all swimming fish, shrimps and crabs, almost all of them had some spiritual spirit beasts, and many other weak spirit beasts sensed Xu Yu's divine thoughts, although they were all panicked and avoided everywhere at first, but they were only quiet for a short time, and they all looked at his location with a hint of curiosity.

This is one of the extremely rare super cave mansions in the entire Quilt Spirit Mansion!

A complete hideaway view.

In the center of the entire cave, there were several simple buildings scattered up, and layers of intoxicating colorful glow shot out from several houses, all of which were the alluring luster emitted by the seventh or eighth level spiritual objects.

"Fusion. ”

After a quick look at the aura in the cave, Xu Yu suddenly gave an order to the thoughts in his body, although the spiritual objects and array in front of him were extremely important, but the fourth-rank aura was the key to making him even more excited.

With the order, nine third-grade spiritual qi immediately began to converge in one place, and where Xu Yu was standing, a large amount of second-grade spiritual energy also surged towards his body like crazy.

After nearly half an hour, when all the spiritual energy within a radius of hundreds of meters around him was consumed, the nine third-grade spiritual qi suddenly burst out into a dazzling luster, and the brilliance was exhausted, and a new spiritual energy appeared in Xu Yu's eyes.

If the first-class aura is clear, the second-class aura is gorgeous, and the third-class aura is noble, then the new aura in front of him is washed away, and the appearance is extremely plain, but Xu Yu faintly felt a mysterious aura, which was quietly emanating from the aura.

This is the fourth-class aura!

Looking at the fourth-class aura, Xu Yu fused into his body, and a terrifying pain immediately poured out of his body, and a ** dense sweat directly converged on the surface of his body and flowed downward.

But unexpectedly, in addition to the pain, he actually found that there was no new stupidity in this fourth-rank aura, and it was far from being full of predatory desires as soon as the third-rank aura appeared.

"Isn't there an additional effect of the fourth-rank aura?" A trace of doubt flashed in his mind, Xu Yu barely endured the pain, and his whole body arrived outside a house in front of him, and then rolled up a chapter of jade slips that had been standing quietly and held it in the palm of his hand.

There is no stupidity, or maybe the effect of the aura is more special.

But what surprised him again was that in addition to the most basic fusion, this fourth-level aura still didn't have any new stupidity, and it was just like a first-class and second-class aura, completely imprinting the things in the jade slip into his mind.

"Strange, is it the wrong method, or is the effect of the fourth-rank aura more special?" A trace of doubt flashed in his mind, Xu Yu just wanted to continue experimenting with other methods, not far in front of him, in a small river, a huge blue crab with a large body and a radius of one meter, but suddenly crawled out of the river, and then opened his mouth and spewed out an ice arrow.

This ice arrow was not aimed at Xu Yu, but towards a strange spirit grass, and after the ice arrow pounced on the grass stem, the entire spirit grass was immediately frozen, but the strange thing was that in the ice, there was a tendency to bloom in the depths of the grass.

Just as the grass was blooming, Xu Yu immediately exclaimed, turned his head to look at the place, he was not surprised by what the herb was, but the fourth-order aura that had not moved had been moving, and it was actually stupid.

The stupid destination was the small Xiaoice arrow released against the giant crab.

"Demon magic?" Shocked again, Xu Yu's expression moved, and he pounced on the demon magic according to the induction in his heart, and then in a short moment, how the ice arrow of the giant crab was cast was clearly touched by him.

But this is not the key, after all, the third-class aura has this effect, the key is that after figuring out all this, Xu Yu's mind was flooded with new ideas, and the information of those thoughts was all to show him how to release his divine thoughts at this time, and mobilize the spiritual power of the left and right water to enhance the power of the ice arrow.

"Enhancement spells?"

A hint of surprise flashed in his eyes, Xu Yu immediately chose one of the ways in which his intention was expressed, and used his divine thoughts to mobilize the spiritual power of the left and right waters, and fused it to the ice arrow, almost at the same time, the ice arrow, which was originally the thickness of a finger, skyrocketed at a speed visible to the naked eye, and in an instant, it became the thickness of an arm, and it was even more terrifying and terrifying!

The giant crab that was performing witchcraft was completely frozen in place, and a layer of boundless doubt erupted in a pair of eyes, why did his demon power suddenly become so strong?

But this kind of doubt turned into panic as quickly as possible, because the giant crab suddenly discovered at this moment that this demonic power became stronger and stronger, but it also became uncontrollable.

In a series of soft sounds, the ice arrow turned suddenly, and with a bang, it shot at a flat ground in front of it, smashing out a deep pit, and the demonic power in the giant crab's body began to flow at several times the speed.

The cancer is completely panicked, what the hell is going on?

The demonic power is getting stronger and losing control, just consuming its demonic power at an alarming rate?

............ "This is the fourth-class aura?!" Xu Yu on the side was also stunned at this moment, after following the idea in his heart just now to enhance the power of the ice arrow, he inexplicably found that he had become the controller of the ice arrow, this kind of control was like his own spell.

That turned out to be the demon magic and spell that others or other demon beasts were casting, and after increasing their power, they became under his control, but consumed a large amount of the opponent's demon power and true yuan power?

Even he had a feeling that even if he wanted to attack the giant crab with that ice arrow just now, it would be as easy as a finger.

Use the opponent's magic and consume the opponent's demonic power, and attack the opponent in turn, which ...... Even when he increased the power of the Ice Archery, he still had a loss of divine thoughts, but this was really not worth mentioning compared to the effectiveness of the fourth-rank aura.

He suddenly discovered that if the effect of the third-class aura was already quite evil, this fourth-class aura was the real insidious!!

Insidious to the point of no attachment!

Overshocked, Xu Yu almost forgot the pain on his body, but then he quickly came to his senses, after all, the fusion of fourth-rank aura was too painful under the first contact.

After waking up, he became ecstatic again, these fourth-class spiritual qi is insidious and insidious, but the practical surname is absolutely unimaginable.

For example, when he encountered the Wind Wing Beast, if he had a fourth-rank aura in his body, after fusing the powerful demon of the Wind Wing Beast, he controlled those demon transformations, but what he had been consuming was the Demon Power of the Wind Wing Beast, and the consequences would be absolutely unimaginable.

Zhizhi was pleasantly surprised for a long time, and then he gradually calmed down again, and began to pay attention to the information that was being read by his habitual surname in the jade slip, since he had already understood the effectiveness of the fourth-rank aura, then the remaining formation bases were another key.

And now this information is related to the sixth-level ban.

The sixth-level prohibition can already be a space of its own, if a monk or demon beast who does not know how to crack it enters, then whether it is an attack and kill prohibition or a defensive ban, it has the same effect, easy to enter and difficult to exit!

Because it is all infinite space, and without a way to crack it, it is difficult to find a way out.

At this point, the sixth-level ban is the real protective weapon, which is much more terrifying than any psychedelic array and defensive array below the sixth level, and even in the sixth-level prohibition, in addition to the general offensive and defensive prohibition, there is also a very special prohibition, that is, a strong prohibition.

That is, the forbidden giver can get a certain degree of effect increase in the forbidden space.

This increase may be strength, speed, or other special aspects, such as doubling cultivation, doubling the absorption of aura, and so on.

As long as it is the giver or with the consent of the giver, it can be used to stimulate one or two times or more of the strengthening effect by consuming the spiritual power of the sixth-level spiritual object.

Just like the swallowing ban that everyone gave in the first sect.

However, according to Yu Jian, strong prohibitions are rarer and rarer than ordinary attack and kill prohibitions, especially those related to cultivation. Even the owner of this Far Thousand Water Cave Mansion had only heard about it, and there were no relevant forbidden formations, spiritual objects, etc.

One of the most significant features of the seventh-level prohibition is that it can rely on the further exploration of space power to cast a teleportation array. No matter how huge the space of the sixth-level prohibition itself is, in the real world, the place it occupies has a certain limit, and the seventh-level prohibition is the super forbidden law that can cut through the real space and make the two originally unrelated places become one.

Of course, the seventh-level prohibition is not only a spatial teleportation array, and other offensive and killing protection, or strength, is much stronger than the sixth-level one.

When Na Yu Jian introduced the seventh-level prohibition, he even revealed a piece of information that surprised Xu Yu inexplicably, in this Thousand Water Cave Mansion, there were two teleportation arrays that had been deployed.

As long as the person who gets the inner mansion transfers one of the magic circles, and then places it anywhere in the outside world, and then places the required seventh-level spiritual object, he can travel back and forth between the outside world and the spiritual mansion at any time.

This could not be surprised by Xu Yu, in this way, as long as he took a teleportation array and put it in the Heavenly Star Mountain, wouldn't he be able to enter and leave the Thousand Water Cave Mansion at any time?

If Li Honghui and others are allowed to cultivate at this time, the effect will only be better!

And with such a secret base, the security of the Nanming faction will be even more solid.

Perhaps the only thing that made him regret this was that even the far master of this cave mansion did not have a strong prohibition on cultivation.

But even so, as long as he thought about the efficacy of the fourth-level aura, as well as everything in the Super Cave Mansion, Xu Yu couldn't help but be ecstatic again.

The trip to Qianshuidong Mansion is really worth it!
