In the midst of the monster beast's smirk, Xu Yu, who was holding the general outline of the third-level formation, suddenly froze with surprise on his face.

Because he suddenly remembered that he was afraid that even if he really mastered the general outline of this three-level formation at the fastest speed, he would not be able to cast a large array outside Tianxing Mountain.

A large array or prohibition, the most important thing is that in addition to the formation diagram, the things that need to be arranged in the array, such as the formation base, the array eye and other spiritual objects, are even more indispensable!

After all, the Great Array is something that can always exist, even if it is not as powerful as the Monk's Control, in order to achieve such a degree, there must be corresponding spiritual objects to support the operation of the Great Array.

This kind of spiritual creature is the base of the formation, the eye of the formation!

For example, a psychedelic array is a kind of water travel formation, and it must have a corresponding water spirit object to mobilize the water spirit power between heaven and earth in order to operate.

And there is no doubt that the higher the level of the big array, the stronger the spiritual objects such as the formation base and array eye will be.

That's the problem.

Although there is a lot of storage in Xu Yu's storage ring now, and there is more support from the Nanming faction behind it, his income, as well as the storage of the Nanming faction, are all from the outside world, and the collection of the three faction formations in the outside world is only a first-level formation, where to find the formation base and array eye spiritual objects that can support the operation of the third-level large array?

Thinking of this, Xu Yu smiled bitterly completely.

Feelings, he was overjoyed just now, only the general outline of the formation, and there was no formation base array eye spiritual object, and it was nothing.

Even many times, a high-level formation or prohibition, formation diagram or outline knowledge is easier to obtain, and the formation base array eye is something that makes people distressed, after all, these outline knowledge and formation diagrams, as long as you take a blank jade slip, you can rub it, it can't be simpler, but the formation base, the formation eye spiritual object, the more advanced the more precious, it is definitely one less piece, if you want to continue to search, I don't know how many years you have to wait to be born.

Just when Xu Yu turned from surprise to bitter smile, the demon beast also froze suddenly, and then a trace of doubt flashed in his eyes, and then he suddenly realized that he spit out another round card from his mouth.

From this round card, a mysterious aura immediately emanated to the surroundings, and the weirdness of the aura directly attracted Xu Yu to look up, and then saw a palm-sized, crystal black jade plaque, flying towards him.

"Huh?"

With a light sigh in his mouth, Xu Yu glanced at the demon beast in surprise before taking the jade card, and almost at the same time, a stream of thoughts suddenly came out of the jade card and surged towards Xu Yu's mind.

Those thoughts were all a huge amount of information, and after Xu Yu gradually sorted out some of the information, the whole person was instantly stunned, and the expression on his face became extremely interesting.

Even he glanced at the demon beast with some surprise, this guy's intelligence is really so high?

He had just remembered the troubles of the Formation Foundation and the Array Eye Treasure, and it sent this jade plaque?

Although this jade plaque is not a spiritual object of the formation base, the information contained in it really made Xu Yu a little surprised and inexplicable, and even more shocked!

Because this is actually information related to a hidden super cave.

Thousand Water River!

The location of Beiling Mansion is in the Kunlun Mountains and the Qinghai-Tibet Plateau, of which the location of Qinghai is the birthplace of the motherland, the Yangtze River, the Yellow River and the Lancang River, and it is not an exaggeration to call it the source of ten thousand waters in the land of Kyushu.

The Qianshui River is the real source of the three major water systems.

After the blockade of those many rivers by the Lock Spirit Array, the secular people in the outside world could not find out the real source, but the Qianshui River also has a huge river basin in the Beiling Mansion, covering almost half of the central and eastern regions.

The super cave house mentioned in the jade plaque is under an open river channel in the middle reaches of the Qianshui River Basin.

This super cave is not an ownerless thing, but the relic of a former ancient monk, and what the former ancient monk is best at is formation!

And the most precious thing in the relic mansion is the general outline of formations at all levels, as well as a kind of array base treasure, and even heavy treasures such as array eyes.

According to the jade information, the cave mansion contains a large number of formation outlines from level one to eight, as well as various formation base treasures corresponding to them.

"Eighth-level prohibition?!plus all kinds of formation bases and array eye spiritual objects required?" After receiving this information, Xu Yu directly gasped, it was an eighth-level prohibition, a super formation that could form its own space.

If there is only the general outline of the formation in this, the key is still the large number of spiritual objects such as the formation base, and the latter is the most tempting for him at present.

Not to mention anything else, even if he just wants to give a third-level array, he must have the corresponding spiritual objects, otherwise everything is empty talk.

It seems that this Thousand Water Cave Mansion is going to take a trip.

Even more suddenly came to his mind, and that was the high-level prohibition.

If he could really get the eighth-level prohibition general outline from it, Xu Yudu suddenly felt that if he could directly break the ban on the cave mansion of Baicaoya on Liuling Island, Baicaoya should be at least a sixth-level prohibition.

If you can break it, you won't have to wait until every ten years to enter it.

It can be said that the temptation of this Thousand Water Cave Mansion is simply too great for him.

In the ecstasy again, Xu Yu was stunned for a moment, and looked straight at the demon beast, "This three-level formation general outline, you got it from the Thousand Water Cave Mansion?"

When the demon beast first told him that it had the general outline of the formation, he thought that the other party was a relic obtained by killing a certain monk, but now it seems that things are not like that.

Because he suddenly remembered that this guy was originally an amphibious demon beast, maybe because its lair might be under the water, he accidentally broke into this Thousand Water Cave Mansion and got these things.

With his inquiry, the demon beast immediately nodded again, but at the same time, the demon beast's eyes also showed a trace of horror and misery, as if it had encountered unimaginable things in the Thousand Water Cave Mansion.

Xu Yu was silent again, closed his eyes, and continued to sort out the information in the jade tablet, and after a short moment, his original ecstasy immediately became extremely strange.

Sensudong ...... According to the reminder of the jade plate's thoughts, this Thousand Water Cave Mansion turned out to be extremely strange, and what the monk laid outside the Thousand Water Cave Mansion was an eight-level prohibition, which was divided into two provinces, inside and outside.

Among them, the outer mansion is placed in the general outline of the first to fifth level formations, the formation base, and the array eye spiritual objects, if you want to obtain these things, it is easy to say that it is easy, but it is also extremely difficult to say that it is difficult.

It must be tested enough to obtain it.

Because it was a self-contained space of the eighth-level prohibition, the scope was extremely large, and those treasures were scattered all over the place, and ordinary monks could only try their luck if they wanted to get it.

Only by holding this black jade plaque can you clearly know where there are treasures and where there are none, and even which treasures are more valuable can be sensed.

It can be said that this black jade plate is the key to the entire Cave Mansion, and if you get it, everything in the entire Outer Mansion is basically clearly visible, even if it is not clear at a glance, and it is the key to entering the Inner Mansion.

Only those who hold jade plates can enter the inner mansion, and what is placed in the inner mansion is the prohibition of level 6 or above, as well as the array eye and array base spiritual objects.

However, if you want to enter the Inner Mansion, it is not so easy, then you must collect a set of Level 1 to 5 Great Arrays in the Outer Mansion, including the general outline of the formation, as well as the array eye and the formation base spiritual objects!

Although this jade plaque has an eye-catching effect, it will automatically indicate where there is a formation base array eye spiritual object, as well as the general outline of the formation.

But damn it, all the other people who entered the outer mansion would have an inexplicable feeling in their minds, that is, the general direction of this jade plaque, as well as its unique mysterious aura.

This kind of mysterious aura is just in the outside world, it's just mysterious, and it only covers a range of more than ten meters, if it is included in the storage ring, there will not be the slightest breath leakage, but in the Qianshui Cave Mansion, then everyone can sense that this jade card is the key to getting the entire Cave Mansion!!

In other words, all the people or demon beasts who enter the Thousand Water Cave Mansion can know that only getting this jade plate is the key to getting the entire cave mansion, but there is only one jade plate.

The result is absolutely predictable.

Whoever holds the jade medal will become the target of everyone else, and when the time comes, let alone inherit the cave mansion, it is a question of whether he can survive or not.

This is the test of strength made by the original owner of the cave to the successor!!

Of course, it seems impossible to do that alone, so those who hold jade medals will also get some favor.

For example, speed, whoever holds the jade card, the aura emitted through the jade card in the forbidden space, its speed will increase by two to three times, and there is also the fact that if the strength of the holder of the jade card is in the Ning Yuan period, then the other people who enter the cave will never exceed the Ning Yuan period, unless he can break the eighth-level prohibition.

This can be regarded as a kind of protection for the holder, otherwise it would be impossible for ordinary people to complete such a test.

Then there is psychedelia, if you want to collect level 1 to 5 formations by relying on the jade plaque in the cave, you don't have to complete it at once, you can enter and exit at any time, after all, the unique aura of this jade plaque can be easily concealed in the outside world.

In order to ensure the safety of the jade card holder in the outside world, the jade card holder can use the power of the jade card to conjure up any kind of appearance to confuse others, unless others can see through the protection of the eight-level prohibition, otherwise as long as the jade card holder escapes from the cave, it is impossible to be chased and killed outside the cave by relying on his face.

Such a jade plate and such a Thousand Water Cave Mansion are indeed very weird.

But even if he felt weird, Xu Yu then laughed again, it seemed that this guy must have broken in by mistake, and then was attracted by the breath of this jade plate, and rushed over to get it in his hand.

However, he was also a little puzzled, the Thousand Water Cave Mansion should be hidden deeper, and how many people would know where it was, and then go in to grab the treasure?

Could it be that there are other oddities in this?

He really didn't know that it was really weird!

As long as the jade plate holder steps into the Thousand Water Cave Mansion, the entire Thousand Water Cave Mansion will bloom with an amazing glow, showing its location to the left and right, and the auspiciousness of that glow, even a fool can know that a treasure is born, and it will definitely attract a large number of monks and demon beasts.

What Xu Yu didn't know was that the Qianshui Cave Mansion already enjoyed a prestigious reputation in the Beiling Mansion, and it contained a large number of formation bases, array eye spiritual objects, and level one to five formations, even if it was Lingxiao Gate, Guiyi Sect, and Pilgrimage Mountain, they were all coveted.

Because the level of auspiciousness of the glow in the current world of the cave mansion is presented by a large number of seventh- or eighth-level spiritual objects, almost every one of them is a rare treasure, even if the three giants are swaying and can't help themselves!

The last time since this demon beast accidentally broke into the Thousand Water Cave Mansion, and then obtained the jade plate to make the Thousand Water Cave Mansion appear for the first time, the huge Northern Spirit Mansion was all shocked.

Everyone rushed towards the local area in unison, although the others did not have jade plates, but there were also those who were extremely lucky, and they landed directly near some strange treasures, and easily obtained the heavy treasures that they had dreamed of before.

Immediately after feeling the breath of the jade card, he became extremely fanatical, even if it was other monks or demon beasts who didn't get the treasure, it was because they went to the auspiciousness of the eighth-level spiritual object, and when they sensed the jade card, it was the key, and they wouldn't miss it.

As a result, this demon beast suddenly found that it was an ordinary low-grade demon beast, and it wanted to fight against the entire Beiling Mansion, so it was directly frightened, and it relied on the jade card to increase its speed several times, and only then escaped from the Qianshui Cave Mansion as soon as possible.

And as long as the jade card holder leaves the cave, the Qianshui Cave Mansion will be closed again, and other entrants will also be automatically transmitted by the eighth-level ban, so the Beiling Mansion at that time was dumbfounded for a while, and some people were tracking the breath when they occasionally found some treasures, and they were about to get them, but they were suddenly thrown out again, and then the entire cave mansion disappeared completely, that feeling was too bad, I could only linger in the Qianshui River and never forget, trying to find the cave, but no one knew that the key to opening the cave was actually on a monster beast that passed by。
