The weakest martial artist? One punch and he's leveled up a whole realm!

A passageway that allows only one person to pass at a time.

Whether it's people coming in or people leaving.

Once an identity discrepancy is detected.

Therefore, escaping would be almost impossible.

At this moment, Ye Xiao's heart was already beating faster and faster.

Because he knew it very well.

He couldn't let others see the unusual nature of his identity.

soon.

The foreman led this group of workers from District 7 to their destination.

Meanwhile, the workers in the sixth section stopped working and handed over their duties.

The two teams began to change shifts.

It was the workers' turn in Zone 7 to begin their work for the day.

Ye Xiao is currently in the group.

He secretly surveyed the surrounding scenery.

he noticed.

At the entrance to this sophisticated industrial facility.

It is continuously supplying magic iron ore into it.

I saw this scene.

Ye Xiao had a vague idea of ​​what was going on.

"There's a high probability that some kind of substance can be extracted from the magic iron ore!"

Suddenly.

Ye Xiao's heart skipped a beat: "Could it be that demonic iron ore can be refined to extract spiritual energy?"

Once the idea comes to mind, you can't stop thinking about it.

Just then.

The foreman shouted, "Now, begin assigning today's work tasks!"

"You! Go to the access point!"

"You and you! Go to the filter end!"

"You go to the core conversion reactor!"

"The rest of you go to the separation and injection ends!"

Hearing the foreman's explanation of the process, Ye Xiao's guess was pretty much right.

This group of people are actually using magic iron ore to refine something!

Ye Xiao's task was assigned to the separation and injection end.

Since Ye Xiao didn't know the way, he followed behind the other workers.

Along the way.

Ye Xiao could also take this opportunity to see exactly how the entire conversion and filtration machine works.

.......

The Demonic Energy Conversion Array is a top secret of the human world.

It is located deep underground in the Chiyuan mine and was jointly built by Taichu Pharmaceutical and Wanqi Heavy Industry.

On the surface, it is an auxiliary facility of the "hematite vein".

In reality, it is the core device of the high-level human alliance that extracts demonic energy and transforms it into spiritual energy.

The location is a group of caves hundreds of meters underground in the Chiyuan mine, and the core device is the size of a football field.

There are seven large reactors, a pipeline network of tens of kilometers, and a rune array covering thousands of square meters.

The heat generated during operation keeps the temperature of the ore vein at several hundred degrees Celsius year-round.

This is the real reason why the mineral vein is "red".

It's not the color of the ore, but the color of the rock that's been heated red.

.......

The first place Ye Xiao passed through.

It is the access point for the "Abyss Rift".

This port serves two purposes.

One is a natural spatial rift connecting the deep parts of the Chiyuan mine.

The human world uses arrays and special metal probes to "pierce" through the cracks into the abyss world and extract demonic energy.

There are nine probes in total, each ten feet long.

Forged from "Demon-Devouring Alloy" specially made by Wanqi Heavy Industry, it can withstand the corrosion of high concentrations of demonic energy.

Another use is for refining magic iron ore.

The magic iron ore itself contains abundant demonic energy.

At the same time, compared to extracting demonic energy with probes, it is more controllable and efficient.

The magical energy absorbed by the probe can be automatically refined and transformed.

But these workers are here to send the magic iron ore into it and speed up the refining process.

After Ye Xiao passed through the first section of the area.

The second area is the "Demonic Energy Coarse Filter Tower".

There are a total of seven giant towers, each 20 meters high and 5 meters in diameter.

The interior is filled with multiple layers of filter materials: monster bone powder, activated carbon, spirit stone fragments, and the forbidden "soul crystal".

The demonic energy entered the bottom of the tower and passed through the filter layer from bottom to top, where some impurities were absorbed.

The primary function of the filtration tower is to remove solid particles, corrosive substances, and some fragments of the Abyss's will from the demonic energy.

However, the filtered demonic energy was still dark red, its toxicity reduced, but it was still corrosive.

In this state, the demonic energy cannot be directly absorbed by the human body.

We must go through the next area.

That is, the third section: the core conversion vessel.

This is a spherical container with a diameter of thirty meters and a wall thickness of three meters, cast from a demon-devouring alloy.

The surface of the cauldron was covered with runes.

The outer layer consists of suppressive runes to prevent the leakage of demonic energy.

The middle layer contains transformation runes, which is the core conversion mechanism for transforming demonic energy into spiritual energy.

The inner layer is an isolation rune, whose main function is to prevent demonic energy from coming into contact with the outside world.

The temperature inside the vessel reaches thousands of degrees Celsius, and the pressure is hundreds of times that of the outside environment.

Therefore, when Ye Xiao was in this space, he could clearly feel that the surrounding temperature was much hotter.

The main operating logic of the core conversion reactor is:

Under high temperature and pressure, and with the help of runes, the demonic energy molecules are broken down and reassembled into spiritual energy molecules.

The process is similar to "cracking," and it also requires a large amount of energy.

But here, there is a large quantity of magic iron stone.

Therefore, magic iron stone itself can also be used as one of the sources of energy.

The demonic energy that has been processed in the previous three areas.

Finally, we will enter the fourth section.

That is, the separation tower.

Here, through multi-layer condensation, adsorption, and sieving, the spiritual energy is separated from other byproducts.

The spiritual energy is transported through pipes to the "spiritual energy infusion point" of the mine, and then injected into the relevant products to make them "rich in spiritual power".

There are several types of by-products.

The first type is high-concentration sulfides, which will be directly discharged into the lava river.

The second type is waste heat, which is dissipated through heat sinks, raising the temperature of the ore vein.

The third type is a black, viscous liquid called "Abyssal Pitch," which was secretly recycled by Taichu Pharmaceuticals for use in the production of banned drugs.

.......

Ye Xiao had already arrived in front of the Separation Tower.

Just now.

Ye Xiao had seen it all clearly.

How exactly does this colossal machine refine the demonic energy from a piece of demonic iron ore, filter it through layers of filtration, and ultimately transform it into the spiritual energy before our eyes?

However, if the method of converting demonic energy into spiritual energy is safe.

So why would this group of people do such a thing in secret?

This is something that is clearly beneficial to mankind.

It's like it's something that can't be seen in the light of day?

.......

Soon, Ye Xiao joined the other workers who had been assigned to the area and began working.

Among this group of people was a man who appeared to be the leader.

All the other workers' eyes were fixed on him.

They seemed to be waiting for him to assign them tasks.

The man scanned the field.

That is, about ten people.

However, it is indeed in the final process, namely the separation tower.

There aren't many things I can do.

The man said, "The same old rule applies. Everyone, first check the safety of the separation tower. Collect any signs of aging pipes, worn runes, etc., and then hand them over to me."

The workers on the field all nodded in agreement.

Ye Xiao was also among them, preparing to go and inspect the separation tower together.

But at that moment...

The man's gaze remained fixed solely on him.

And he called out, "You stay here first."
