Let's start by analyzing the sun

Yellow sand filled the sky.

A group of figures appeared on a sand dune.

One of them was none other than Cheng Han.

Having arrived in the Mirage Sand World for two days, he had a general understanding of the basic situation of this small world.

For example.

The temperature difference between day and night in this world was terrifying. The daytime temperature could reach above seventy degrees, while at night it would suddenly drop to minus thirty degrees.

In the deep night, it often snowed in the desert.

It was not the common flaky snowflakes.

But spherical snow grains.

Also, for example.

This world was not an absolute dead zone.

Despite the extremely harsh environment, life continued to survive tenaciously, and there were many species in the boundless sea of sand.

Among them, the most numerous and widely distributed species was – sand ants.

"Gacha!"

"Gacha!"

Accompanied by the sound of stepping on sand.

Cheng Han stepped onto the top of the sand dune.

The main purpose of his trip was to conduct an on-the-spot investigation of the desert conditions in order to complete the exploration task assigned by the Heavenly Killing God Lord.

Behind him.

Two Mystics and several Mystics followed closely behind, all with cautious expressions.

At this time.

The temperature had already exceeded fifty degrees. If ordinary people took a breath of air, it would definitely cause burns to the respiratory tract or lungs.

Even the Mystics had to carry a Mystic artifact called the "Pure Domain Ring".

After this thing was activated, it could maintain the temperature within a certain range at a more comfortable level, and purify various debris and harmful substances in the air.

In short.

The Pure Domain Ring was equivalent to a transcendent version of an air conditioner plus an air purifier.

However.

Cheng Han did not use the Mystic artifact.

Within a two-meter radius around him, an invisible barrier formed, which not only maintained the temperature at around twenty degrees, but also isolated all dust.

A group of Mystics and Arcanists occasionally peeked at Special Envoy Cheng, all with a hint of surprise on their faces.

Because their naked eyes could see the Special Envoy, but their mental power could not sense him at all, as if Special Envoy Cheng did not exist at all.

The most incredible thing was that if they used a transcendent perspective to observe, the area where Special Envoy Cheng was standing was actually just a blank space.

This was really a very confusing thing.

The Mystics could not figure out the mystery, they just felt that the Special Envoy's methods were extremely novel, and it was really the first time they had ever seen it.

The two Mystics were stronger and noticed something different.

They vaguely sensed that within the invisible barrier around Special Envoy Cheng, it seemed to be another completely different world, and their mental power was swallowed up when they extended it.

In fact.

This was exactly a new method mastered by Cheng Han.

After following the Light Shuttle God General for an unprecedented space shuttle, the All-Knowing Eye analyzed a large number of mysteries about space.

The Space Inscription that had been condensed before was also completed to the second level.

Cheng Han drew on the God General's light egg for shuttling through space, and combined it with what he had learned, to deduce a powerful secret method – the Mirage Space.

The "Space" in it represents the space-based Mystic method.

The "Mirage" in it symbolizes the law of true and false illusions.

All in all.

This is a composite new Mystic method.

Even measured by the standards of a Mystic Overseer, it is enough to describe it as "powerful".

Soon.

Cheng Han took the lead in climbing to the top of the sand dune and began to look into the distance.

The Arcanists stopped when they saw this.

"Whoosh!"

The scorching wind swept across.

Rolling up the sky with sand and dust.

Cheng Han looked around, his eyes locked on the northeast direction, and his eyes flickered slightly: "The large sand dunes over there will soon collapse."

The Arcanists looked at each other, all half-believing.

After just a few glances, he said that the sand dunes dozens of kilometers away were about to collapse, really?

A Mystic named "Nie Zhou" boldly asked: "May I ask Special Envoy Cheng, what is the reason for this?"

Cheng Han did not play tricks and replied: "The rock layer supporting the sand dunes has been almost completely hollowed out, and it may collapse at any time."

Nie Zhou said "Oh": "I see."

The Arcanists were even more suspicious.

Can you judge the underground situation from such a distance?

But because of the origin of the God Lord's special envoy, no one dared to question it.

Cheng Han keenly noticed the thoughts of the Arcanists.

The corner of his mouth curved, his eyes turned to Nie Zhou, and he asked: "You should be practicing the Stone Spirit Mystic method, right?"

Nie Zhou respectfully replied: "Yes!"

Cheng Han pointed to a place not far away and issued an order: "Use your earth-shaking secret method and aim a shot there."

Nie Zhou immediately obeyed the order.

A majestic wave surged in this person's body, and a cloud of gray light emerged from his right hand, which then condensed into a gray spear.

Nie Zhou took a step forward and waved his hand forcefully to throw the gray spear out.

The gray spear instantly passed more than two kilometers and quickly fell towards a concave valley between the sand dunes.

It can be seen from the attack distance alone that this Mystic's strength is quite strong and is definitely a leader in the Mystic group.

Immediately afterwards.

The gray spear hit the sand and turned into a gray light that disappeared below the sand layer.

Next second.

"Boom!"

A loud noise.

The ground shook violently.

The sand dune where everyone was standing was affected by the vibration, and a large amount of sand rolled down quickly.

The Arcanists could not stand firmly and all flew up with the wind.

After a while.

"Rumble!"

An even louder bang.

The source was the sand dunes in the distance.

The Arcanists were shocked and subconsciously turned their heads to look over.

Subsequently.

They saw the vast scene of mountains collapsing and the earth cracking.

I saw several large sand dunes suddenly sinking a large section downwards, and violent sand and dust rose up instantly, instantly covering the sand dunes.

"Boom!"

"Boom!"

Muffled sounds continued one after another.

The vibration also continued non-stop.

After another ten seconds.

The sand and dust subsided slightly, and the outline of the sand dunes could barely be seen.

A group of Arcanists glanced at it and were all stunned.

As far as the eye can see.

But I saw several thousand-meter-high sand dunes, all of which were half as short out of thin air.

This undoubtedly confirmed Special Envoy Cheng's judgment.

There were a large number of cavities in the rock layer at the bottom of the sand dunes.

When the rock was vibrated, causing the cavity to completely collapse, the sand dunes would naturally fall downwards.

Therefore.

Then there is the scene in front of you.

At this moment.

A group of Arcanists were finally convinced.

Nie Zhou sincerely praised: "Special Envoy Cheng has unparalleled insight!"

Others nodded in agreement.

Cheng Han smiled slightly, and then gave an explanation: "If I guessed correctly, the thing that hollowed out the rock layer should be a type of sand ant called 'Stone-Eating Ant'.

"This kind of ant colony, which mainly lives underground, likes to gnaw on 'black phosphorus rock' in order to obtain the nutrients in it.

"After thousands of years of gnawing by the ant colony, countless cavities have appeared inside the rock layer, and the foundation of the sand dunes is already crumbling."

Including the two Mystics, a group of Arcanists listened very carefully.

This group of people had not been in the Mirage Sand World for long, and they knew very little about the local species groups. This was the first time they had heard about the Stone-Eating Ants.

In fact.

All of the above.

All are information sensed by the third-level Life Crown Inscription.

Just now, during the process of climbing the sand dunes.

The powerful power of this Mystic Seal sensed all life within dozens of kilometers.

This includes Stone-Eating Ants.

Next.

Cheng Han again used the power of the Life Crown to perceive the underground rock layer through the ant colony.

Then he saw the continuous cavities, so he judged that the rock layer was about to collapse.

After a few seconds.

The vibration gradually subsided.

Cheng Han issued a new order in a timely manner: "Notify the other outposts to immediately search for sand ants underground, and then send the samples over."

Nie Zhou quickly responded: "Yes!"

Previously.

Cheng Han had been scratching his head, wondering how to search for abnormal traces in the vast sea of sand, and then determine whether the Nest of Calamity was hidden in this world.

After all, this world does not have a world will, and there is no way to use external force.

But now.

He finally found the key to breaking the situation.

That is – these tiny lives living in the rock formation.

Cheng Han waved his right hand again: "Let's go! Continue to investigate!"
