The sudden opening of the nine-yuan killing array caught Yun Tian off guard, he originally knew that the power of the nine-yuan killing array was amazing, but he had also thought that the formation could only be opened at least when someone broke through to the vicinity of the ninth layer of the enchantment and triggered the ninth layer of the enchantment, and before he had heard that there was already a fog between the eighth layer of the enchantment and the ninth layer of the enchantment, so it stands to reason that those who had entered should touch the mist first before opening the ninth layer of the enchantment. According to Yun Tian's judgment of the Nine Yuan Killing Array, there will be a special transition layer between the eighth layer of the enchantment and the ninth layer of the enchantment, and the space of this transition layer will be very large, because the existence of this transition layer is to dilute the mutual interference between the light true qi and the dark true qi.

No matter how the depraved line of the light system colludes with the dark system, there is always an opposition between the elements of the light system and the elements of the dark system, and once the light system true qi and the dark system true qi come into contact at any time, there will inevitably be a violent opposing reaction, and for a formation that strives for stability, this kind of opposing reaction is not advisable, so arranging this kind of magic circle will definitely not arrange the enchantment of the light system and the dark system too close.

And the reason why Yun Tian knew that a cloud of mist would form on the periphery of this ninth layer enchantment was because he understood what the function of that fog was. The mist lies between the eighth layer of the dark elemental enchantment and the ninth layer of the light elemental enchantment, which is actually a kind of blocking effect, to put it bluntly, the mist is a kind of transition agent, a neutralizing agent, so that there will be no violent reaction between the true qi of the two opposing attributes, so as to ensure the stability of the formation.

But Yun Tian never thought that the change would be so sudden, he didn't have time to withdraw from the passage at all, and the ninth layer of the enchantment was suddenly opened, and in this way, the Nine Yuan Killing Array was quickly opened.

And what surprised Yun Tian was that the Nine Yuan Killing Array experienced a rapid contraction the moment it opened, which greatly reduced the scope of the entire Nine Yuan Killing Array, but unfortunately, the Nine Yuan Killing Array let go of the group of people who fled before, but it just restrained Yun Tian in the array.

At this time, Yun Tian wanted to cry, why was he so unlucky, but he was bound within the formation?

He wanted to leave as soon as possible, but once the Nine-Yuan Killing Array was opened, how could it be so easy to escape? Almost at this moment, the most powerful effect of the Nine-Yuan Killing Array after it was opened was also produced.

Nine Yuan Killing Array, as the name suggests, this is not a docile and gentle formation, but a killing array, and it is a terrifying compound killing array!

The compound killing array is the most terrifying of all formations, because the attacks it releases are complex and sharp and deadly, and the formation itself has its own energy source, and it will continue to absorb the surrounding true qi to replenish itself when fighting with the enemies in the formation, especially the compound killing array, it is very likely that it will absorb a large amount of energy from the living forces in the formation after the formation is launched, so as to further enhance itself. In other words, some high-grade compound killing arrays may become stronger and more powerful, and this nine-yuan killing array belongs to this category.

Just after the Nine Yuan Killing Array was opened, its first reaction was to start quickly absorbing the true qi in the formation, trying to form a vacuum of true qi in the formation, so that the people in the formation could not get the source of the true qi.

This is a terrifying feature of the Nine Yuan Killing Array, which can make the true qi of the people in the array gradually consume, thus making it difficult for the true qi to continue, and eventually the true qi will dry up and die.

Fortunately, Yuntian is not a soft persimmon that can be kneaded by others, he has his own sea knowledge space, which can provide him with a steady supply of true qi, and at the same time, although the nine-yuan killing array will drain the true qi in the formation, its principle is to use the nine-element elements to target the people in the formation, for example, if you have the golden true qi, then use the restraint of your fire true qi to absorb your true qi, in short, it is to form a true qi advantage for the people in the formation.

The problem is that Yun Tian is a special case, he is an extremely rare martial cultivator who can control a large number of different elements, and at the same time he is a formation mage who is familiar with the Nine Yuan Killing Array, and he can provide and supplement the nine true qi involved in the Nine Yuan Killing Array, and even more, he has mastered more true qi that does not belong to the Nine Yuan elements, such as thunder elements, such as true dragon qi, such as Xingchen true qi, although the number is not much, but they all belong to the nine elements of the nine, this time the Nine Yuan Killing Array squeezed Yun Tian's true qi, but was immediately judged by Yun Tian and targeted。

Since he knew that the Nine Yuan Killing Array could extract the true qi of the trapped person, of course Yun Tian would not sit idly by, so he immediately converted the true qi in his body into thunder true qi, of course, it was better to convert it into true dragon qi and star true qi, the problem was that Yun Tian's current strength could not do that, so the thunder true qi became his best choice.

It was also because of his decision that the Nine Yuan Killing Array suddenly realized that there was an outlier in the formation, and the reason for the self-control of the large array was that when the Nine Yuan Killing Array was launched, it selectively "ignored" Yuntian.

The Great Array was still activated, but it was not Yuntian who was harmed, but those who were in the mist between the eighth and ninth layers of the barrier.

"Hey, why is my true qi flowing as fast as flowing water?"

"Oh no, I feel my true qi disappearing quickly!"

"Quickly swallow the pill to replenish the true qi, quickly!"

"Who has the pill, give me some pills, my true qi will be completely consumed if it goes on like this!"

The people trapped in the mist shouted in horror, they could already feel the rapid flow of true qi in their bodies, but there were almost no alchemists in the people present, even if there were, it was impossible to have too many pills in their hands, not to mention that relying on pills to maintain the true qi in the body was not an effective way to deal with it, no matter how your true qi was replenished, it would eventually be absorbed by the Nine Yuan Killing Array, there could be no exceptions, the only exception was to secretly look at the lively Yuntian in the eighth layer of the enchantment, he was almost unaffected at this time, and was carefully observing the changes in the Nine Yuan Killing Array inside。

And in that mist, as the true qi continued to flow, the people in the formation also became a little irrational.

"Damn, whoever dares to get close to me, you all stay away from me, otherwise Hugh blames me for being unkind!"

"No one wants to get close to me, don't try to absorb my true qi!"

"What are you doing so close to me, do you have bad intentions?"

People became suspicious, and some people were short-tempered and disagreed, so some people actually started to move.

The sound of fighting in the fog continued, and this kind of fighting further intensified the conflict, which made the martial cultivators present gradually lose consciousness and attack each other frantically.

From time to time, people were killed, and the blood and qi of those who were killed were absorbed by the Nine Yuan Killing Array, and soon only the dried corpses were left behind.
