Facts have proved that Xie Yuanshan's movements are still very fast.

Less than half an hour after he left, a team of black uniforms walked in front of Chen Kai in a neat queue.

They are tall and tall, with a resolute look on their faces, and their every move is full of the iron and blood wind unique to the military.

"It's worthy of the elite team in Xie Yuan's mountain pass."

Chen Kai probed their ranks, and was secretly shocked in his heart.

Except for the two officers in the lead, who were bronze-level, the rest turned out to be black iron level, and they were all black iron level high-level.

With such strength, thirty people in this line are enough to be called elite!

"You're Chief Chen, aren't you?"

"Chief Xie has ordered, and this operation will be commanded by you."

"The two of us will serve as vice-captains to help you complete this mission."

One of the leading black uniforms respectfully walked up to Chen Kai and saluted.

Chen Kai glanced at the military badges on their shoulders, both of them were second lieutenant ranks, and their ranks were not low.

It seems that Xie Yuanshan attaches great importance to this investigation.

"How long will it take you to prepare before you can go?" Chen Kai asked him.

"We're ready to go." He replied in a sonorous voice.

Chen Kai nodded with satisfaction and slowly stood up from the ground.

After this recovery, his body is no longer as tired as it was at the beginning.

"Let's go now, then."

He really didn't want to waste too much time here.

"As you wish." The man saluted Chen Kai again.

"That's right...... I forgot to introduce myself to you, my name is Li Baisha."

"The person next to me is called Zhang Huacheng, you can call us Lao Li and Lao Zhang."

After a short conversation.

Surrounded by two bronze and twenty-eight black iron ranks, Chen Kai came all the way to the edge of the town.

After witnessing the scenery outside the town, Rao is Chen Kai was mentally prepared in advance, and he couldn't help but be shocked at this time.

The level of pollution in the extradimensional space can be much worse than that of the earth.

Although the earth is heavily polluted, it is also full of human civilization.

Doomsday barriers stand in the bronze walls, scattered in the land of China, protecting the last fire of mankind.

But here, there is only an endless stretch of purple filth.

There was no sign of life as far as the eye could see. qδ

There are no colorful flowers and trees, no birds and animals, just an endless desolate purple soil.

Some areas even evaporated purple filth, condensing like a haze that could not be dispersed all year round.

"We're calling the area of this town the safe zone." Lao Li explained to Chen Kai.

"In the safe zone, there are our people patrolling 24 hours a day, so it's relatively safe."

"But it's different outside the safe zone, and it's full of ferocious beasts."

"They're like a source of pollution, and everywhere they pass, the soil is filthy and no grass grows."

"If it weren't for the fact that all the beasts that invaded the earth from here were all exterminated by us, I'm afraid our earth would have become like this."

Listening to Lao Li's words, Chen Kai nodded thoughtfully.

If those invading beasts are allowed to roam the earth, the environment of the earth will only get worse and worse due to the influence of the filth on their bodies.

"There really isn't a paradise in this world." Chen Kai couldn't help but sigh.

"Not necessarily." Lao Zhang, who had been silent, spoke.

"Someone once strayed into the fourth layer of another dimensional space, and then escaped back."

"According to him, in the fourth dimension, a place like this polluted by filth is only one

A small part."

"Most of the area is beautiful, and although there are strange beasts, they are far less numerous than the first three floors."

"So he thinks that the reason why there are so many alien beasts in the first three layers of the interdimensional space is probably because they were artificially driven out."

"According to that person, the first three layers of the extradimensional space should be regarded as a place of exile, and it is specially used to exile alien beasts."

"Of course...... This is just his personal speculation, and we don't know if it's true or not."

It's possible.

Humanity's awareness of the fourth level of extradimensional space is close to zero.

In such a situation, all speculations can come true.

"How are we going to get out of town and walk freely in the dirt?"

Looking at the endless filthy soil in front of him, Chen Kai felt a little difficult in his heart.

In normal times, he would not have this kind of trouble.

But he had just consumed a lot of beast power, and he could no longer drive the slime to release the purification skill.

Naturally, he could not lead a group of soldiers to walk in the dirt.

"Don't worry, sir."

Lao Li waved his hand, and a mechanical exoskeleton that was three meters tall and had a streamlined shape appeared in front of him.

And as he set an example, a group of soldiers summoned the same mechanical exoskeleton.

The powerful alloy mount, the alloy armor attached to the mount, the jet-black grenade rifle mounted on the arm......

Almost every design, even every element, can tug at Chen Kai's heartstrings.

At the same time, he also noticed that the soldiers were wearing a spatial ring on their hands.

Obviously, these mechanical exoskeletons were previously stored in their spatial rings, which could be easily removed.

"The outer shells of these power armors are made of alloys that are immune to dirt erosion."

"With these power armors, we can walk on the filthy soil normally without worrying about being eroded by the filthy soil."

Looking at Chen Kai's surprised appearance, Lao Li's words were full of pride.

Chen Kai's tone carried a hint of envy: "I really didn't expect that you would have such a good thing."

"If only I could drive this thing......

Twenty minutes later.

Chen Kai and his entourage of 31 people wore power armor and walked in the filthy soil.

Chen Kai's limbs were wrapped inside this power armor, and his entire body was supported by a bracket made of alloy.

Walking is not as heavy as expected, but light and fluttering, and it makes the sizzling sound of the device running.

With each step, the power armor creates a massive impact that leaves deep footprints on the ground.

Looking at the legs of the power armor again, there was no sign of erosion.

Chen Kai had never heard of an alloy that was completely immune to the erosion of filthy soil.

"It's kind of interesting."

He ran hard a few times, and the whole person jumped several meters away as if he was weightless.

It felt like losing gravity, and the multi-ton power armor fluttered like a feather.

In addition, he studied the rifle on the armor.

This rifle fires not only large-caliber bullets, but also howitzers.

In addition to the surprise, he also had a question.

"Is this power armor really a creation that can be researched with the level of technology on Earth?"
