Everyone was anxiously busy, and the formation had been reduced from fifteen kilometers to three kilometers, and the strength of the formation had more than doubled.

The range of the formation has been reduced, and the surrounding defensive circle has also been strengthened. The masters stood shoulder to shoulder, forming a battle formation to meet the challenge that would erupt at any time.

The challenge came as soon as it was said, and Wang Ruiyang's worries were fulfilled.

The juice of ginseng is not easy to use, and the two methods that Zhou Xueyao studied before are also ineffective. The demon beasts thrown into the formation became food for flying insects and were able to reproduce rapidly.

"Stop!" Nangong Zhi stopped throwing demon beasts inward, and asked everyone to just strengthen the formation. Also, if you have the chance, be sure to get some samples.

Get the sample to Zhou Xueyao, so that Zhou Xueyao can work out the solution. At present, the mutation of flying insects has nothing to do with Zhou Xueyao, and everyone still understands this reason.

But danger came faster than you could have imagined. These new mutated flying insects only took about a minute to break through the formation!

You must know that the current Heaven and Earth Sealing Array uses the technology of the Ocean Group, and it has been reduced to three kilometers. Its defensive capability was almost four times that of the previous Xuanhuang Group's Heaven and Earth Sealing Array.

However, such a large array was easily broken through by flying insects.

Seeing this, Wang Ruiyang's pupils contracted.

Seeing this, Nangong Zhi screamed: "Attack, supernatural powers!!"

This time, the masters were prepared, and almost immediately, the Great Array of Heaven and Earth was wrapped by the divine power that was close to the end of the world.

The flying insects that had just broken out of the large array instantly fell into the quagmire.

However, more flying insects swarmed out in the rear, and although the Great Array of Heaven and Earth Sealing Array continued to repair itself, it had almost no effect. A large number of scarlet flying insects followed.

Three minutes later, the outside of the Heaven Sealing Earth Sealing Array was almost covered with flying insects, and the Heaven Sealing Earth Sealing Array itself was almost invisible.

However, for the time being, the flying insects were suppressed by the supernatural powers on the surface of the large array. However, at this time, the faces of the masters were solemn and even frightened. For these newly mutated flying insects, it is gradually a little unbearable!

As the number of flying insects increases, the supernatural powers are gradually becoming more and more difficult. Suddenly, several Transformation Stages let out an exclamation, and their supernatural powers collapsed because they couldn't suppress too many flying insects.

Almost instantly, these flying insects crawled all over the bodies of the three god transformation stages. In the blink of an eye, the three transformation periods disappeared, and the number of flying insects doubled!

Zhou Xueyao couldn't help but gasp when she saw it, "The flight speed of these flying insects has more than doubled, and the devouring speed and reproduction speed have also doubled!"

The next few god transformation periods reacted quickly, and once again used their magical powers to suppress the flying insects. But everyone is struggling.

Nangong Zhi immediately commanded, and the two magic masters passed, and the two supernatural powers went down to trap these flying insects.

took out some and sent them to Zhou Xueyao for research, and the rest took the stupid methods of the past again - using supernatural powers, sword qi, etc., to split the flying insects into small balls, and then incinerate them with real fire.

The flying insects are really a lot stronger, but fortunately, they are still afraid of fire, especially the true fire of the master of the law. However, the masters of the law have said: These flying insects are more resistant to burning!

Zhou Xueyao was not idle, with the help of the masters of the Dayang Group, plus her own assistants, etc., she started the experiment again.

However, half an hour passed, and sweat appeared on Zhou Xueyao's sideburns;

An hour passed, and sweat came out of the tip of Zhou Xueyao's nose, and beads of sweat stuck to the white and tender skin, and the reddish tip of the nose was like a white lotus condensed under the morning mist. However, no one paid attention to this at this time.

What everyone pays more attention to is Zhou Xueyao's research results.

"All poisons are invasive!" Zhou Xueyao's face was a little pale, "At present, all the means that can be thought of have been used, whether it is viruses, bacteria, fungi, or all kinds of poisons, pills, etc. At best, these new flying insects are somewhat uncomfortable at first, but they recover quickly and antibodies are produced in the body.

It feels like ...... I opened a door and let out the devil in the back!

At present, the conditions are limited, and it is temporarily impossible to observe and study the genes of flying insects. But I have a feeling that this kind of flying insect is not naturally generated, but is an artificial product, an artificial life.

It is impossible for nature to produce such a terrifying flying insect that mutates so quickly!"

Zu Qianyue frowned slightly when he heard this. Actually, I don't pay attention to your speculations, I just care about one thing: you still have a way!

However, at this time, Zu Qianyue's tone was also a little anxious and even impatient.

Zhou Xueyao glanced at Zu Qianyue quietly, and said calmly: "I'm not an immortal, for the time being, I can only say that we haven't found a way yet." Moreover, ordinary research and experimental methods are no longer useful.

It is time to observe the genes of flying insects and design a target virus to block the action of their genes.

I know you don't understand (very arrogant). To put it simply, the experimental conditions here are not suitable for studying these flying insects for the time being. I only hope that the holy flames of the Tiandu Sect, the Ming Sect, and the Immortal Yin Sect can come over soon. ”

Hearing Zhou Xueyao say this, Zu Qianyue opened his mouth, but he couldn't say a word, and finally could only sigh together and turn away.

Since Zhou Xueyao can't produce results in a short period of time, she can only work hard and look forward to the arrival of the holy flame.

As the night gradually sank, the sunset reluctantly set down the mountain, but high in the sky, the air carrier turned on its headlights, and it was clearly visible within a radius of three kilometers, and it was also clearly distinguishable within a radius of five kilometers.

Although everyone is a master, in the face of these tiny flying insects, it is better to have light.

More and more flying insects are gathering outside, and it is becoming more and more difficult to rely solely on supernatural powers to block them. Masters need to rest too!

However, everyone is not stupid, they are also dividing the flying insects, and constantly refining them with real fire. If there is no real fire, or the temperature of the real fire is not enough, use the formation.

The formation induced by the high-grade spirit stone is very powerful.

Also, because the Heaven Sealing Array is a one-way pass, some people will also attack to stuff the flying insects back into the formation. But all this can only treat the symptoms, not the root cause.

Everyone was busy in an orderly manner, and even the masters of the Ocean Group and the strategic alliance took over part of the defense.

At this moment, everyone is working together and cooperating intimately. No one would have imagined that the two sides, which were fighting for life and death more than a month ago, would be able to work together in the face of the common crisis of mankind.

Time passed minute by minute, and Zhou Xueyao's research was already in trouble. Conventional methods are no longer working, and Ms. Zhou is now trying to synthesize an enzyme, or a new hormone that can affect flying insects.

But for a while, Zhou Xueyao didn't know where to start.

Suddenly, one of Zhou Xueyao's assistants and students couldn't help but speak, "Teacher, I have an idea. ”

Zhou Xueyao looked at her student, a sweet-looking girl in her early twenties. But she is the most clever little girl under her own hands.

Giving Miao Xiaoyu an encouraging look, Miao Xiaoyu whispered, "Teacher, your previous two temporary methods were superficially beneficial to flying insects, so they were made to accept them and not cause resistance.

But for living beings, the biggest benefit is actually longevity!

The lifespans of the flying insects are very short, so can we increase their lifespan?

I remember that my teacher used to have a study that the lazier you live, the longer you live. For example, turtles. And trees generally have a very long lifespan, and they don't move at all!"

After speaking, Miao Xiaoyu looked at Zhou Xueyao nervously. However, Zhou Xueyao's eyes brightened, "Yes, go on." ”

"Ah...... Oh, teacher, I remember earlier we studied a kind of aluminate after spiritualization, which can cause nervous system retardation, etc. But a larger effect can inhibit the division of genes.

When the gene division is suppressed, the lifespan will naturally be longer. But it can also cause sluggishness, sluggishness, and even dementia in life!"

Zhou Xueyao's eyes suddenly burst into brilliant light, "It seems to be a kind of spiritualized alum, which has such an effect!"

With the direction, it took less than thirty minutes for Zhou Xueyao to have research results again. Sure enough, the new drug did not cause an immune response from the flying insects, and was absorbed by the flying insects.

Then the insects crawled lazily in the vessel.

Reactions begin about 15 minutes after flying insect poisoning, reaching the limit after 30 minutes.

Spiritualized alum?

Zu Qianyue's eyes brightened again. Just 10 kilometers away, they excavated an alum mine, roughly estimated to be three kilometers in circumference.

Wang Ruiyang muttered beside him, "I have heard before that all poisonous snakes and poisonous insects must have an antidote within three steps! This is the way of heaven! Perhaps, this alum is the 'antidote' to flying insects!"

It's just that not everyone can find an antidote!"

Zhou Xueyao nodded to Wang Ruiyang, and Zu Qianyue immediately organized personnel to excavate alum. The spiritualized alum is beautiful, as gorgeous as a diamond.

However, no one studied these at this time, and the alum was crushed and stuffed into the body of the demon beast. Under the effect of the spell, the bones and flesh of the demon beast were all filled with alum, and then a wisp of true yuan was left in the heart of the demon beast to continue its life, and it was thrown into the formation.

Some people even directly crushed the alum, mixed the spiritual spring to dissolve the rain, and sprinkled the solution into the large array.

This time the effect is even better. As soon as the demon beasts and others were thrown in, there was a dispute among the flying insects. The flying insects that grabbed the flesh and blood of the demon beasts first were killed by more flying insects because they were a little slower to react.

The results were jaw-dropping. Even some flying insects that had already flown out of the formation turned around and returned.

After more than an hour, the flying insect curled up back into the cave again, leaving a red cloud with a diameter of one kilometer slowly surging.

The red clouds swelled, falling and contracting. The flying insects also flew more and more slowly, and many of them simply stopped on the rocks and stopped moving.

Wang Ruiyang swallowed a mouthful of saliva and stammered to ask Zhou Xueyao what she should do.

Zhou Xueyao looked at it and proposed: "I think, don't intensify these flying insects for the time being, and strengthen the defense and wind seal first." Wait for the flame to arrive. ”
