As soon as Dong Lin's words came out, it was equivalent to breaking an iron law on the side of the domain, and everyone present felt incredible.

The entire hall fell silent.

Dong Lin loves face more, in fact, he also had a preliminary idea through the simulation of divine consciousness, as for whether he can succeed, he himself has no bottom in his heart, but such a questioning gaze makes Dong Lin very uncomfortable.

Qian Jue may have seen Dong Lin's dissatisfaction, and explained with a smile: "Hehe, senior, I don't mean anything else, this sonic function is resolved, it's the first time we've heard of it, it's just a little surprised!"

"Hmph, what's this?!There are always some things in this world that you don't know, just as the so-called world is full of wonders! It's just a small sonic wave, and the poor Dao does have the means to counteract this sound bat demon sound!" Dong Lin had to put on an unfathomable appearance in order to increase his credibility, "Let me tell you the simplest way first, you quickly order someone to dig a dungeon deep underground, it doesn't matter if it's simple, as long as you can live in people, this is very simple for cultivators!" Then let those disciples hide inside, leave the vents, and temporarily seal the other exits with boulders!

This is actually a simple treatment of the first plan, but this kind of magic sound in front of him is not a simple sound, it is extremely penetrating, what is the effect, Dong Lin is not easy to say, at least the deep formation should be able to block a certain magic sound, it is better than nothing.

However, the elders looked at each other, no one moved, and the effect of Dong Lin's words did not seem to be ideal.

Thinking about it, it is also true that he can't show superior strength, and it is difficult to impress the monks of the Ning Dan period with his bluff alone, but fortunately, he knows the root of the matter, and he is the head of the four, so he always feels that this situation will not become worse.

So he appeased the other three and nodded in agreement to Dong Lin's request.

This scene made Dong Lin hold a breath of anger in his stomach, strode towards the center of the formation arrangement, and reached out to take the array plate in his hand.

As a Xuan-level formation, the Earth Spirit Formation is actually a relatively cumbersome formation, through the refining array, you can control the arranged array flag, Dong Lin sneaked his divine sense into the array, and it didn't take much effort to use his divine sense to drill and figure out the operation mode of the entire formation.

The earth spirit formation is basically to absorb the spiritual energy in the valley through a special magic circle with the help of the array flags laid out, forming a spiritual power barrier that can absorb attacks, but the main application is the earth spiritual power.

It doesn't matter what spiritual power is used, the key is how to make the circle can neutralize the attack of the sound wave.

Dong Lin got the array plate and flew into the sky with the array plate.

Seeing this, several elders didn't say much, and followed closely behind Dong Lin to see how to counteract the magic sound of the sound bat.

Dong Lin flew all the way to the spiritual power barrier, and because he controlled the array disk, Dong Lin could arbitrarily integrate his divine sense into the protective barrier and feel the subtle changes in the protective barrier.

In fact, the Earth Spirit Barrier is not useless at all, in fact, the Earth Spirit Barrier is also a diagonally flowing Earth Spirit Power to form a protective circle, and when the sound wave passes through the barrier, it has actually been weakened by the barrier.

It's just that the earth spiritual power is only a spiritual power after all, not an entity, and it can't completely block sound waves like a thick rock wall.

But it is this kind of malleable spiritual power that allows Dong Lin to realize the second plan.

It is easy to figure out the operation mode of spiritual power, but if you want to change the fixed mode of spiritual power and perform high-frequency vibration according to Dong Lin's ideas, then this work is very difficult, very tedious, and the mental consumption is immeasurable.

Even if Dong Lin's divine sense was comparable to the Ning Dan Period, he was a little overwhelmed by the calculation.

As a last resort, Dong Lin could only wake up Xu Can and let Xu Can hide in the Qiankun Treasure Wheel and cooperate with himself to perform divine sense calculations.

Time passed minute by minute, Dong Lin stood in mid-air and never moved, and the elders of the Zitian Sword Sect were already a little whispering, but fortunately, they were afraid of Dong Lin's face, and these elders were all talking with a voice.

However, it didn't take a while, and one of the elders who went to arrange for the excavation of the underground palace rushed back, clearly saying that Dong Lin's method of explaining worked, and the disciples who were simply hiding from the demon sound in the palace obviously reduced their pain a lot.

The deep stratum blocked some of the magic sounds, but it only weakened the strength of the magic sounds, so that most of the disciples in the foundation building period could withstand the magic sounds, and it was still impossible to fall asleep.

With this as a guarantee, everyone suddenly ignited hope that this mysterious Qingzhen might really be able to solve the crisis in front of them.

Dong Lin put in ten percent of his efforts for the sake of his own face, and in a short period of time, in fact, Dong Lin himself relied on this divine sense to manipulate and explore, and he had already formed a prototype of a magic circle to crack the magic sound.

The next thing is to try, the earth spirit formation is a fixed array, and a fixed rune array has been depicted on it, Dong Lin wants to change the array, it is impossible, once it is forcibly changed, it means that the entire magic array is destroyed, and he can only find another way.

Dong Lin had to improvise a formation disk, and through a principle similar to a parallel circuit, he linked it with the original Earth Spirit Array to gain more refined control.

In the eyes of others, two arrays, one large and one small, hung in front of Dong Lin, and Dong Lin kept trying to trim on the small array, and then the earth spirit barrier in mid-air began to fluctuate.

With the secret support of Xu Can, Dong Lin used the new array disk to change the fluctuation of spiritual power little by little, and sure enough, the influence of the magic sound fluctuated strongly and weakly, indicating that the effect of the magic sound could be changed through the fluctuation of spiritual power.

This made Dong Lin's confidence greatly increased, so he still let go of his courage and adjusted the strength and frequency of fluctuations of his spiritual power little by little according to the results of the divine consciousness simulation.

Although there are individual differences in the demon bats, after all, they are a race, and the magic sounds emitted are also concentrated in one band, as long as Dong Lin finds out the inverse frequency of this band, then it can basically be said that it is done.

"Qingzhen Daoist, there are really some doorways, no wonder the sect master values it so much!" Feeling that the intensity of this magic sound decreased little by little, Tong Hu couldn't help but open his mouth to express his admiration.

"Yes, I told you a long time ago, this Qingzhen is not simple, I once broke into the demon camp alone, retrieved the antidote and saved the Chixia Fairy, this Peiyuan period is estimated to be just a trick for others!

Qianjue followed and explained, in fact, his heart just now had been hanging, if Dong Lin was really powerless, then it would be difficult for him to do it, not only could he not blame Dong Lin, but he also had to think of comfort, and he had to help explain on his side, and he would definitely be in a dilemma at that time.

Now that the situation is very good, then he is prescient, and the pride in his heart is gone.

Elder Wei seemed to have some doubts, "You said that Daoist Qingzhen is a senior master, but why is his spiritual strength comparable to ours at most, and there doesn't seem to be much surprising about it?"

Qian never thought so, "The seniors have always done things inscrutablely, how can we see the depths? Maybe in his old man's opinion, just using the cultivation of the Ning Dan stage is enough to solve this problem, and he can't show it in front of us juniors!"

But as soon as Qianjue's words fell, the entire Earth Spirit Formation suddenly shook, and it actually stopped running?!

For a moment, the ice blade fireball fell from the sky, and the entire quiet valley was filled with a demonic roar.

It happened suddenly, fortunately, most of the low-level disciples were hiding in the underground palace, and the demonic attack of the Ice and Fire Demon Bat destroyed some buildings in the valley, and did not cause casualties, and the elders of the Heavenly Sword Sect who were present immediately rose into the air and used their respective immortal sword skills to attack.

And the demon bats that reacted were also black and oppressive, and pounced directly towards the quiet valley.

And the culprit Dong Lin still doesn't care, nervously operating this array, he can't do anything, if he wants to completely change the function of the Earth Spirit Array, he has to break and stand, stop the Array, and redeploy, after Dong Lin finds out the law, he must re-modify the Earth Spirit Array according to his own ideas, and before the modification is completed, the Heavenly Sword Sect must resist the attack of the demon bat, which is not a difficult thing for the Thousand Peerless Elders.

The only thing that is a little regrettable is that Dong Lin is too involved and forgets to say a word to them.

Qian Jue and the others looked at the demon bats that were killing more and more, and they couldn't help but have some drums in their hearts, what kind of situation is this, this late night, there is no prohibition to support, such a loud fighting sound, if the other demon beast groups are provoked, the Sword Sect will be completely finished that day!

At the moment, this situation is too dangerous, Qian Jue has to be in a hurry, but he can't help it, the array is in Dong Lin's hands, and even if he wants to return to the array on his side, it can't be opened, the elders of the Heavenly Sword Sect are not good at formation!

Fortunately, Dong Lin didn't make these elders anxious for long, as the joy on his face appeared, the entire formation restarted, and after this activation, the entire magic circle appeared with colorful halos of different shades, like hitting colored bubbles of different sizes, blocking the attacking magic sounds one by one.

The moment the circle was raised, the magic sound that had been filling my mind disappeared!
