After a long time, Yang Yan's mind was taken back from the jade slip, and the slightest wave was set off in his usually calm eyes, and his heart trembled slightly, as if he had seen something incredible, and even he couldn't keep calm.

What was recorded in the jade slip was the Yunxiao Sword Formation, which was not wrong, but it was not the same as the sword formation of the fourth layer as he guessed, and the two could not be compared at all, they belonged to different levels.

According to the brief description of the Yunxiao Sword Array in the Jade Slip, this array was obtained by a genius disciple of the Yunxiao Divine Sect in a ruin by chance, and after refinement, it was found that it was powerful, and it was invincible among its peers.

This genius sect master can be described as a legend of the Yunxiao Divine Sect, and his statement is far and wide, not only admired by the disciples of the Divine Sect, but also known to everyone in the entire vast Qianyu, and even several major states close to the Qianyu have left traces of him.

His name is invincible, and the sword is invincible!

This is not his real name, but the name changed after the rise, because he started with the sword, and reached a peak in the way of the sword, the sword refers to, the invincible, and the name of the sword is invincible, from which the name of the sword is invincible, these three words are enough to make his enemies frightened, and make those who admire him bow down and worship, as for his original name, no one has known it for a long time, and no one has ever mentioned it.

In his life, he has fought countless battles, challenged countless geniuses, and has not been defeated.

He regarded the sword as his second life, inseparable, and even never married a wife in his life, using the sword as his companion, even if he no longer needed to use the sword, he still carried the sword that accompanied him all his life.

It was the Cloud Sword Formation that forged his legendary life, but it was also his own superhuman talent and amazing understanding, as well as a firm martial arts heart, he evolved all kinds of powerful sword attack methods from the original Cloud Sword Array, creating his super combat power.

The Yunxiao Divine Sect did not practice the way of the sword, or the way of the sword was not strong, but since the invincible sword took charge of the Divine Sect, the way of the sword has risen rapidly and has become an inseparable lineage of the Yunxiao Divine Sect.

Later, after Jian Invincible left the Yunxiao Sword Array, he left the Divine Sect alone, one person and one sword, and there was no news of him since.

This is the end of the description of him in the jade slip, this jade slip is not the original version that Sword Invincible got from the ruins, but he carved it according to his lifelong perception of the way of the sword, but it is also extremely precious, many disciples of the Divine Sect can not get it, and these introductions seem to be dictated by himself.

Invincible to the sword, after Yang Yan read Yu Jian's account, he also had to admire, a hundred years of rise, this is a predecessor who was born for the sword, is obsessed with the way of the sword, and deserves the respect of many people.

But what made his mood fluctuate even more was the specific description of the Cloud Sword Formation in the back.

The Yunxiao Sword Formation, to be precise, is not a specific sword formation, it only has the most primitive formation structure, and all the sword formation methods are generated based on this primitive structure, which can be said to be extremely flexible and unpredictable.

The core content of it is a sword-forging method, which pays attention to the traction of all the pure qi in the world, ingests into the weapon, forges the inside of the weapon, and removes all impurities, even if it is just mortal iron, it can also make it solid, and the quality is improved by more than one grade, and the power is powerful.

The sword cast by this method of sword casting, the sword is invincible and called the Yunxiao sword, and once the Yunxiao sword is cast, it forms a Yunxiao sword array, and hundreds of millions of Yunxiao swords fly together, so powerful, destroy the heavens and the earth, drive away evil spirits and subdue demons, punish gods and subdue demons, no problem!

However, the more powerful the means, the more difficult it is to cultivate, and this sword-forging technique is naturally the same.

To forge the Cloud Sword, the most basic thing is to draw the pure qi of the world to forge the sword used to form the sword array, and the so-called pure qi is the purest power in the world, such as pure yang qi, pure yin qi, thunder power, etc., what kind of power depends on what kind of power the cultivator cultivates, and there is not much restriction on this.

This sounds very simple, but in fact, this kind of power is scattered in every corner of the world, and martial artists can use it when they cultivate to a certain extent, but these powers are often not pure, and cannot be regarded as pure qi.

And on top of this, how to pull these pure qi forging swords is also a problem, this is not a matter of brute force to press into the sword, there must also be a special forging method to forge the sword into an indestructible cloud sword, and this, but also requires the soul strength of the forger, only a strong enough soul power can support the precision of forging, otherwise a bad one, so that the sword and the pure qi explosion are possible.

In addition, the demand for pure qi is also a big problem, because most of the forces existing in the world are not pure, to exercise them pure, then a large amount of this power support is needed, and the pure qi required to forge a cloud sword is also extremely large, the higher the grade of the sword to be forged, this demand increases exponentially, and the difficulty of forging is also greater.

Another point, although this sword forging technique does not have clear requirements for the sword used, only you have enough ability, even if it is just a sharp weapon, but in fact, the sword grade used for forging cannot be low, because the low-grade sword can't withstand the forging of pure qi at all, if you force it, before you can forge it, the sword will blow up.

Under various conditions, it can be seen how difficult it is to forge the Sky Sword, even if ordinary people spend their whole lives, it is difficult to forge a Cloud Sword.

And even if the Sky Sword is just cast, how to form a formation is the most critical issue.

It is mentioned in the jade slip that the Yunxiao Sword Formation can be a sword battle array or a pure sword array. The so-called sword battle array, is the main body of the sword formation is not a sword, but a person, one person and a sword, the formation of the formation actually belongs to the category of the battle array, the standard sword battle array, in addition to the requirements for the sword, there are also requirements for people, the number of people who form the sword battle array, the number is determined by the scale of the sword battle array, and these people must be cultivated to be similar in strength, and have the same kind of attribute power that fits the Yunxiao Sword, but also cooperate with each other tacitly, figure it out, and work together.

As for the pure sword array, it is a simple sword array, which is launched by the person who cultivates this array, without the cooperation of others, and the sword moves when it is intended, and in a single thought, ten thousand swords come out together, killing everything.

However, this pure sword array requires the soul power of the initiator to reach an extremely high level, after all, the launch of the pure sword array is controlled by the mind of the initiator, and the mind is directly linked to the soul power of the warrior, the soul power is not strong, it is difficult to control a sword, and how to kill the enemy in a formation.

Relatively speaking, the sword battle array has no requirements for people's soul power, as long as they can control the sword in their hands, it is enough.

These two kinds of sword formations have their own advantages and disadvantages, whether to choose the sword battle array or the pure sword array, it depends on how the cultivator chooses, not to mention that this is not a contradiction, nor is it a question of choosing one or the other, as long as there are conditions, you can cultivate both, of course, for the lone wanderer, it is natural that you can only cultivate the pure sword formation.

Since the Yunxiao Sword Array is only a primitive structure, the attack methods of the Sword Array are all based on the intention of the initiator, so the natural flexibility is extremely strong and it is not easy to be targeted, but for beginners, the lack of attack means will cause the power of the Sword Array to be greatly reduced, and it will not be able to cause the intended effect.

Just like the sword formation on the fourth layer, that's it, the attack method is monotonous, so that Yang Yan has an opportunity to take advantage of, otherwise it is difficult to say whether he can break the formation, of course, in this case, it will be difficult for some strong people, after all, Yang Yan also took a lot of effort to break out of the formation.

This is not to say that the sword array is the Yunxiao Sword Array, it is still too far away, it is just that it is imitated according to the characteristics of the Yunxiao Sword Array using the real sword to test the trialists, if it is really the Yunxiao Sword Array, even if it is the weakest kind, it can instantly tear Yang Yan into nothingness.

And in fact, this imitation of the Yunxiao Sword Array, its power is also very considerable, equivalent to a weakened version of the Yunxiao Sword Array, the cultivation conditions have also been reduced to the minimum, there is no need for pure qi forging, and the people who form the Sword Battle Array do not need the same attribute, of course, it is naturally the best to be able to have the same attribute, for the cultivators of the pure sword array, although the requirements for soul power still exist, otherwise how to control so many swords at the same time, but it is also reduced a lot.

Although the sword that forms the sword formation no longer requires the forging of pure qi, it must be of the same grade, and the shape must be the same, but compared to the real cloud sword formation, the starting point is lower I don't know how much, as long as you want to, even all weapons can form a sword formation to kill the enemy.

Originally, after Sword Invincible obtained the Yunxiao Sword Array, he did not cultivate it immediately, but reluctantly cultivated a weakened version of the Yunxiao Sword Array, and the result surprised him, such a sword formation was still strong, allowing him to show his prominence among many geniuses and make a statement.

The first time he practiced the real Yunxiao Sword Formation was when he was at the peak of his Qi Refining Realm, he reluctantly forged thirty-six Yunxiao Swords with human-level high-grade treasures, and forcefully crossed the chasm to obliterate the strong people of the Lingyuan Realm.

What is the strength of the so-called Venerable, Yang Yan is not clear, but even the powerhouse of the Tianxuan Realm does not have such a title, he must be a peerless powerhouse above the Tianxuan Realm, but he was destroyed under the Yunxiao Sword Array, which shows the strength of the Yunxiao Sword Array.

He didn't know how many Yunxiao Swords had been forged in the end, and what level of strength had reached, but if hundreds of millions of Yunxiao Swords really came out together, destroying the heavens and destroying the earth, and punishing the gods and subduing the demons, it would not be a lie.

And in the life of the invincible sword, he used the Yunxiao Sword Formation as the base, created many powerful swordsmanship, and the attack methods of the Yunxiao Sword Formation also summed up some offensive techniques, all of which were left in the jade slip, which was really a valuable asset for Yang Yan, after all, this can be regarded as making up for the lack of fixed attack methods in the Yunxiao Sword Formation.

Perhaps, in the future, Yang Yan will be able to exert the full power of the Cloud Sword Array without relying on these means, but now, these attack techniques are too important.
