Hearing Lu Ban's words, Old Song smiled.

"I understand what you mean, but it is not easy to pull the future of this foreign land back to the limits of Hegra. We have tried everything, but we can only stabilize the pollution here, but we cannot slow down the pace of the Outer Gods' revival."

"We will make the final decision in three days at the earliest."

He said.

"Can we go take a look near the core?"

Lu Ban asked again.

"Near the core? Are you crazy?"

Old Song glanced at the gradually dimming beam of light in the center of the island.

"The pollution there is far beyond imagination. Even if we wear such protective clothing, we can only stay in it for dozens of minutes."

"You should also confirm the situation here in the end, you can take me with you."

Lu Ban did not retreat because of this.

"You can take me with you, too."

Shia also said.

"...Okay, when night falls, I will take people to confirm the status of the core one last time. You can follow me then, but it is very dangerous there, so you'd better be careful."

Old Song seemed to be persuaded by Lu Ban, and he answered.

After nightfall, the island did not become cold, but the hot, grainy wind continued to blow.

When the sun fades and night falls, the red color in the center of the island becomes faintly visible, like an everlasting sunset.

Although Old Song said he was ready to run away, he still conscientiously prepared two small protective suits for Lu Ban and Xiya.

This protective suit looks like just a layer of cloth, but it fits well and is breathable yet can block pollution. Lu Ban tried it and found that ordinary sharp weapons could not cut through the clothes. He jumped into the water and the clothes could even help him absorb oxygen from the water.

Lu Ban thinks this kind of high technology is great.

Of course, he and Xia couldn't walk as fast as the giants. Of course, judging by their size, they couldn't stand on the shoulders of the giants, so they sat on the hands of the two giants.

Crossing the beach, the team led by Lao Song entered the forest of the island.

The forest had already mutated due to pollution, but due to the suppression of the core, it had not yet reached the point of chaos. The leaves were dark purple, azure blue, bright yellow and other metallic colors, and the tender buds on the branches had begun to wriggle, as if new branches were about to grow.

There are no other animals on the island. Those creatures had turned into monsters when the pollution first spread and were cleared out by the people in the Brilliant Realm. At this moment, there was silence and even the moonlight was intoxicated.

clatter--

A crisp sound suddenly came from the white box hanging on Lao Song's shoulder, like the sound of a clock turning.

clatter--

The sound came at a certain rhythm, once every tens of seconds.

"This is an instrument that can detect pollution concentration. When the frequency of the sound becomes higher, it means that the surrounding pollution concentration has increased."

Old Song knocked on the box.

"Believe me, you won't want to hear it get loud."

clatter--

As soon as he finished speaking, the box made another sound.

"The pollution here is already under control quite well. Using deep well technology, we are able to confine the pollution from the Outer Gods to a radius of no more than three kilometers in the center of the island, but the pollution is always leaking out."

Lao Song explained as he walked steadily through the woods. The surroundings became increasingly darker, but the feeling of silence had disappeared, replaced by a subtle noise.

The noise was rustling, coming from the top of every plant, from under every fallen leaf, and from every crack in the rocks.

Everything grows, and all plants want to sprout again.

The sound of the plants crawling was so creepy that it made your teeth ache.

But to people in the Brilliant Realm, these are just noise.

"It seems that the impact of pollution here has deepened again."

Old Song said this and waved his hand.

One of the giants pulled a firearm from the containment unit they were hauling.

Taking it in his hand, he pulled the trigger.

The next moment, a blazing flame gushed out from the muzzle of the gun, and the almost blue-green flame suddenly swept away all the plants in front.

There were no ashes, no fire spreading, everything sublimated and turned into gas in an instant.

Even the ground was burned into the appearance of crystal glass.

Lu Ban couldn't help but take a closer look at the spray gun.

[It can burn without oxygen, clean, no pollution]

[It can burn most of the organic matter and is the best choice for cleaning]

[Exquisite design, industrial standard, can be used as car interior decoration]

“That’s amazing.”

Lu Ban exclaimed in admiration.

"The core area is ahead."

Old Song ignored Lu Ban's admiration and pointed forward.

After the forest was burned, the view suddenly became wider.

I saw that in the center of the island, where the mountains should have been, there was only a black pillar.

The cross-section of the pillar was a perfect circle, encompassing an area with a radius of about three kilometers.

Some kind of light shone through the black pillar, illuminating the night sky with a crimson glow.

“This is the deep well.”

Old Song said as he walked forward.

"Through some technology, we can fold space. As long as the curvature of the folded space is higher than the speed at which pollution escapes, we can control the pollution within this area."

His words are easy to understand.

The spread of pollution has a speed. No matter what kind of pollution it is, it is impossible for it not to spread and pollute other people. Just like Lu Ban, if he had not seen Aldebaran, then the great existence of Aldebaran would never be able to find him.

For ordinary people, the lower limit of the speed of pollution diffusion is close to the speed of light. In other words, when you see those gods, you have already been polluted.

So in theory, if a foreign area can escape from the pollution source at a speed faster than this diffusion speed, then this foreign area will never be polluted.

This is also one of the more feasible plans among the several plans envisioned by the Glorious Realm for the survival of civilization.

But the problem is that with current technology, people in the Glorious Realm are unable to create equipment that would allow them to travel safely beyond this speed limit.

However, while studying these plans, Brilliant Realm unexpectedly obtained some other technologies, such as the deep well technology currently being used.

There are several directions in the research on the speed of pollution diffusion. One is the acceleration school that advocates active escape, and the other is the restraint school that advocates restraining pollution. The restraint school proposes that if an infinitely expandable space can be researched, then is it possible to place the source of pollution in this space, allowing the space to extend infinitely, thereby achieving the result of sealing the pollution source?

Although truly infinite space has not yet been achieved, they have indeed built a deep well device that can limit the spread of pollution to the greatest extent.

"In the deep well, the Outer God is sleeping."

As soon as Old Song finished speaking, he heard a slight roar coming from the dark pillar.
