Let's start by analyzing the sun

Heavenly Ring B.

Underground.

An important experiment is underway.

Over two hundred Mystics from various minor spirit realms are present, as a matter of course.

Naturally, Li Xu and Zhao Qihuan, the two Mystics from the Tai'an Minor Spirit Realm, are among them.

In the distance.

A large expanse of mottled, faint haze is slowly swirling in the underground space, creating a rather fantastical scene.

This is precisely the most troublesome thing in spring - spore clouds.

The two Mystics simultaneously cast wind-based Mystic Arts, creating a gentle breeze to keep the spore clouds at bay.

At the very center of the crowd.

Wen Xueqing, the Mystic in charge of the Heavenly Banyan Hall, holds a communication device in his right hand and says in a deep voice, "Activate the monitoring array!"

"Yes!"

"Understood!"

Several responses sound one after another.

In just one second.

A miraculous sight appears.

Six objects resembling wooden stakes around them spew out streams of green light, converging into a green halo, which then transforms into a light green image.

The picture clearly shows an extremely complex underground area, teeming with a large number of Void Insects gnawing on wood.

"Buzz… buzz…"

The sound of gnawing is quite dense.

Even with just a cursory glance, it can be determined that there are at least two hundred insects in the swarm.

This is undoubtedly a small-scale Void Insect swarm.

A slight commotion immediately ripples through the crowd, and faces are etched with surprise.

Some Mystics can't help but whisper to each other.

"This effect… doesn't it look a lot like a Mystic Array for image monitoring?"

"It really does, just a little blurry, but not by much."

"What kind of method is this?"

Every Mystic present can see that the image looks like a Mystic Array, but it definitely isn't one.

Because there are no "Mystic Discs" carved with Mystic Runes, or "Mystic Crystal Panels" to control the array.

Wen Xueqing takes in everyone's reactions, a smile appearing on his lips.

This Mystic in charge suddenly walks to the side of the image and gently fiddles with it.

With this action, the image rotates slightly.

Wen Xueqing then fiddles in the opposite direction, and the image rotates in the opposite direction accordingly.

He then swipes downwards forcefully, and the image quickly flips over, turning the top into the bottom and the bottom into the top.

Such a display can simply be described as "controlled by will."

A large group of Mystics are completely stunned.

Although Mystic Arrays can also perform this kind of operation, it requires manipulating the Mystic Crystal Panel and consuming a certain amount of mental energy.

But the Mystic in charge simply moved his hand… this truly subverts everyone's understanding.

A Mystic can't suppress his curiosity and asks, "Please enlighten us, Master Wen, what kind of method is this?"

Everyone else pricks up their ears, waiting for the master's answer.

Wen Xueqing says in a light and casual tone, "This is a little trick that Vice-Hall Master Cheng of our hall came up with in his spare time, called 'Tree Spirit Secret Guard.'"

He points to the six tree stumps on the ground and roughly explains, "These are the 'Tree Spirit Cores,' which can rely on the power of the Divine Banyan Tree to connect to the 'Secret Guard Eyes' in the distance."

As soon as these words are spoken.

The Mystics are truly shocked.

How could this be a small trick?

It's clearly an incredible skill!

The Divine Banyan Tree is an existence of extremely high level, and only wood-spirit type Mystic Seals above the Third Order, that is, Mystic Seals at the Mystic Overseer level, can sense the power of the Divine Banyan Tree.

Perception is already so difficult, let alone borrowing the power of the Divine Banyan Tree.

Wen Xueqing immediately adds, "Everyone, this is not the focus of today's experiment."

The Mystics look at each other with subtle expressions.

Not the focus?

This is the damn focus!

Although everyone already knew that Special Envoy Cheng has the ability to leverage the power of the Divine Banyan Tree, no one expected that this powerful ability could be "granted" to others.

Every Mystic understands that there's a huge difference between using it yourself and letting everyone use it together.

Wen Xueqing uses one sentence to bring the straying topic back, "Everyone, today's experiment will begin in ten seconds."

The crowd immediately quiets down.

Today's demonstration is precisely – the method of using poisonous spores to eliminate Void Insects.

This is also the main purpose of the Heavenly Banyan Hall gathering Mystics from various minor spirit realms.

In the image.

The Void Insects are still diligently gnawing away, as they have done for tens of thousands of years.

And not far away.

Several apprentices are starting two Science-Magic internal combustion engines, and several Red Armor Army warriors are dragging two pipes and connecting them to the blowers.

Everything is ready.

Ten seconds later.

"Bang! Bang!"

Continuous light sounds come from the two internal combustion engines.

The machines are started.

Wen Xueqing says with a smile, "A month ago, I participated in an experiment to clean up Void Insects, and at that time the internal combustion engines were as loud as explosions.

"And after several batches of Void Insects were killed by the poisonous spores, they actually evolved insects with very keen senses, able to hear the sound of the machines from several kilometers away.

"When the machines were started at that time, all the Void Insects within a few kilometers radius quickly fled far away."

From these words, it can be seen that the adaptability of the Void Insects is ridiculously strong, and their rate of evolution is also unimaginably fast.

It's not without reason that these things can pose a considerable threat to the Divine Banyan Tree.

Wen Xueqing points to the machines and adds, "This is the latest model of internal combustion engine that our hall has researched and developed after a series of improvements.

"They use special sound-absorbing materials and are also engraved with spirit runes to reduce noise. Now the running sound is not much louder than speaking.

"Originally, the ground vibration was very obvious, and standing close to it would make your feet numb. Now you can't feel any vibration on the ground at all."

The above comparative explanation immediately gives the Mystics the most direct impression.

That is – the Heavenly Banyan Hall is an extremely serious, responsible, and effective institution.

Li Xu and Zhao Qihuan exchange a look, and at the same time, a thought arises in their minds – this seemingly unintentional explanation is actually a highly purposeful promotion.

The only intention is to enhance the influence of the Heavenly Banyan Hall.

It must be said that this approach works extremely well.

The two Mystics have only been in the Mystic Palace for a few days, and they vaguely have an impression in their minds – among the many institutions in the Mystic Palace, the Heavenly Banyan Hall is the most outstanding one.

Soon.

There is new movement in the image.

Several Void Insects, who were originally happily gnawing on wood, suddenly start attacking each other frantically, as if they have gone mad.

The Mystics are all watching intently.

Wen Xueqing lightly taps a Void Insect from afar and makes an "enlarging" gesture with his hands.

The light and shadow change in mid-air, and the insect is immediately magnified ten times.

Everyone clearly sees that the Void Insect's eyeballs become completely red, and a dark green liquid is constantly flowing from its orifices.

Its behavior becomes extremely manic, first biting its companions to death, and then tearing its own abdomen fiercely.

"Buzz… buzz…"

The scene of the stomach rotting and the intestines being pierced is extremely disgusting and frightening.

Wen Xueqing begins to explain again, "Over the past few months, the Heavenly Banyan Hall has conducted many experiments and summarized an important rule.

"If a type of poisonous spore is used multiple times, the Void Insect swarm will evolve resistance, which Special Envoy Cheng has named 'Poisonous Spore Antibodies.'

"After changing to another type of poisonous spore, the same thing will happen as long as the experiment reaches a certain number of times, and the Void Insects will also have antibodies against the new poisonous spore."

The faces of a group of Mystics change.

Wen Xueqing suddenly changes the subject, "However, the above is not absolute."

He continues to talk eloquently, "We have also discovered another rule: when Void Insects have five to eight types of antibodies, they will not develop new antibodies.

"In other words, there is a limit to the resistance of Void Insects. As long as the poisonous spores are changed continuously, this method can still effectively eliminate Void Insects."

The faces of the Mystics relax somewhat.

Wen Xueqing adds, "To date, the Heavenly Banyan Hall has researched and developed as many as twelve different types of poisonous spores."

At this time, in the image.

This crazy Void Insect, insatiably greedy, has gnawed off most of its own abdomen and finally dies.

Such a scene is simply hair-raising.

Wen Xueqing smiles and says, "What you are seeing now is the 'Hunger Poisonous Spore' that our hall has recently developed.

"This poisonous spore can greatly stimulate the Void Insects' desire for flesh and blood, causing them to kill each other, or even gnaw themselves to death alive."

Hearing this.

The Mystics feel more and more that the work of the Heavenly Banyan Hall is not only outstanding, but simply outstanding to the extreme.

In just a few months, they have created as many as twelve types.

A quarter of an hour later.

The experiment is over.

The results are immediately available.

The entire Void Insect swarm in the image, along with the surrounding insects, a total of more than six hundred and eighty, have been killed.

This "visible" good effect is more convincing than any language, and immediately "conquers" all the Mystics.

A Mystic can't wait to ask, "Master Wen, when can our 'Hundred Harmony Minor Spirit Realm' receive the Science-Magic internal combustion engine and the poisonous spores for killing insects?"

Other Mystics also start talking at once.

"Our Chengxi Minor Spirit Realm also wants them!"

"Please issue them as soon as possible, Heavenly Banyan Hall, so that our Zhengjun Minor Spirit Realm can also use them as soon as possible."

For a time.

The scene is quite enthusiastic, everyone fearing to fall behind.

Wen Xueqing promises with a smile, "The Heavenly Banyan Hall will issue the related equipment the day after tomorrow, each minor spirit realm will have a set. Everyone, please enjoy yourselves in the Mystic Palace for one day tomorrow."

An enthusiastic response immediately comes.

"Thank you, Master!"

"The Heavenly Banyan Hall has really done a great thing!"

Faced with this scene.

Li Xu and Zhao Qihuan have many feelings.

Not only did they do a good thing, but they also did it in an impressive and extremely beautiful way, earning unanimous praise from all the minor spirit realms, which is rare in the entire Mystic Palace.

It can be foreseen that once the poisonous spore insect killing method is rolled out on a large scale, when the major Mystic Pavilions report to the Mystic Palace, there will definitely be no shortage of words of praise.

It goes without saying that Special Envoy Cheng's guidance is indispensable behind this.

In comparison.

In the past, some institutions in the Mystic Palace have not done good things that "benefit the palace and the people," but they did not attach so much importance to publicity, and more or less seemed a little黯然失色.

*

The next day.

Li Xu and Zhao Qihuan got up early on purpose, intending to go to Heavenly Ring C to admire the giant ship made of stone, which is famous.

This stone ship, which is talked about everywhere in the Mystic Palace, has a rather strange name – aircraft carrier.

No one knows why Special Envoy Cheng would take such a name.

Having finished writing about the aircraft carrier, it's time to wander outside the Mystic Palace and see the world outside.
