Zhu Hengyu did not go out to explore in person, sitting in Tianmo Village, Zhu Hengyu was responsible for collecting all the exploration information.

The immigrants who go out to explore are responsible for constantly passing the discoveries on the exploration road back to Tianmo Village.

In just two days, the entire Demon Island was thoroughly explored through the full-scale exploration of more than 3,000 immigrants.

Looking at the large amount of information gathered, Zhu Hengyu quickly made a decision.

The most suitable construction site for Demon City this day is the center of Demon Island.

One came because there was an underground fountain.

Secondly, the magic island was flat on this day, nothing special.

Since there is nothing special, it is naturally built in the very center of the island, next to the island fountain is the most suitable.

The fresh water gushing from the fountain is the only source of fresh water resources in Tenma Island.

The entire Demon City, built with this fountain as the core, is definitely the most suitable.

After deciding the address of Jiancheng ...

Next, under Zhu Hengyu's order.

More than 3,000 immigrants all moved.

The first thing they did was to use mud and weeds to make mud bricks.

After being burned by fire, it will be made into a rock solid fire brick!

The building materials of Demon City will be dominated by these fire bricks.

Don't underestimate the fire bricks, Tianmo Village, the original Anping Village, all the buildings are built from fire bricks.

Although fire bricks are made of clay.

But its strength is stronger than rock.

Especially the clematis growing on the Heavenly Devil Island is as strong and hard as steel!

The buildings built with these special fire bricks are almost indestructible.

Not to mention, how the three thousand immigrants burned fire bricks around the clock to build the Demon City.

the other side……

Accompanied by Zhu Xiaomei, Zhu Hengyu drove all the way to the east of the fountain at the center of Tianmo Island.

According to the information sent by those three thousand immigrants.

Ten miles east of the central fountain, there seems to be a vein!

A small river flowing along the water of the fountain.

Zhu Hengyu and Zhu Xiaomei went all the way to the east.

Walking for more than ten miles all the way, finally, Zhu Hengyu saw what the immigrants said, that mine vein!

Looking at it, the bottom of the clear stream exudes ice blue light under the sunlight.

If it is just light, I am afraid no one will take it too seriously.

But the problem now is that Zhu Hengyu and Zhu Xiaomei were standing by the river, and they felt a icy chill that was spreading from the bottom of the river.

After observing it for a while, Zhu Hengyu was still unable to determine what the vein was.

Between doubtful observation ...

Gao Pengyi ran away from a distance.

Originally, Gao Pengyi was responsible for the firing of fire bricks and the construction of Demon City.

But Gao Pengyi's ability is very strong, but when he really needs to make a decision, he still wants Zhu Hengyu to make up his mind.

Running all the way to Zhu Hengyu, Gao Pengyi was about to ask for instructions, but was interrupted by Zhu Hengyu.

"You came just right, you help me see, what is this mineral vein?" Zhu Hengyu shouted.

Hearing Zhu Hengyu's words, Gao Pengyi temporarily gave up the request and looked down at the bottom of the river.

I only glanced a little ...

Gao Pengyi shook his head in disappointment: "This is just an ice crystal mine. Although it belongs to a rare mineral deposit, it is worthless."

Ice crystal mine?

Hearing Gao Pengyi's words, Zhu Hengyu immediately frowned.

I don't know why, for the name of ice crystal mine, Zhu Hengyu always felt a little familiar.

Where seems to have heard of ...

Looked at Zhu Hengyu's puzzled expression.

Gao Pengyi said: "Generally, when low temperature quenching is needed, some ice crystal ore will be needed, but most of the time, this kind of ore is not very useful."

After hearing Gao Pengyi's words, Zhu Hengyu couldn't help being disappointed.

But I don't know why, Zhu Hengyu always feels where he seems to have heard the name of the ice crystal mine.

And most importantly, this cryolite should be very important!

and many more……

While thinking hard, a flash of light flashed through Zhu Hengyu's mind.

I remembered……

When I talked to Cangshui about the trade between the two tribes, Cangshui once mentioned cryolite!

This cryolite is the circulating currency of the sea snake family.

For the Sea Serpent, this cryolite is a hard currency forever.

The status of cryolite in the Sea Serpent Clan is like the position of the Magic Energy Stone in the Demon Clan.

After taking a long breath, Zhu Hengyu's eyes shining brightly: "You help me to explore, how long is this ice crystal vein, and how much is its reserves?"

She shrugged helplessly.

Gao Pengyi said: "I found this ice crystal mine long ago and have detected it."

This ice crystal vein is almost all over the whole Demon Island.

As long as the turf of Demon Island is lifted up to ten meters, you can see these ice crystal ores.

As for the amount of reserves, there is really no way to detect this temporarily.

All in all, this ice crystal mine, over 100 kilometers in length, covers the entire Demon Island.

As for other parts, it is impossible to detect.

For the time being, Gao Pengyi cannot detect the area below the sea surface.

Perhaps this ice crystal vein is only a hundred miles in diameter.

Perhaps this ice crystal vein can stretch thousands of miles.

As for how much, for the time being, it cannot be detected.

Nodding excitedly, Zhu Hengyu said: "Then you probe, what is the total reserves in the hundreds of kilometers of veins in this area?"

Facing Zhu Hengyu's problem, Gao Pengyi smiled and shook his head bitterly, "This is really hard to say for the time being."

Without really digging, it is impossible to know the quality of this vein.

If they are all primary ice crystals, then the total value of this vein is not much higher.

If they are all superior ice crystals, the value of this vein is crazy.

I want to know exactly the total reserves of this vein.

Then it is necessary to conduct spot sampling throughout the island.

It takes at least three years to detect before it can roughly determine its total reserves.

With a bitter smile, Gao Pengyi sighed: "Unfortunately, the ice crystal mine is useless, if it is the magic energy stone mine."

Magic energy stone mine?

Hearing Gao Pengyi's words, Zhu Hengyu couldn't help laughing.

Yeah, if it's the Mengneng Stone Mine, it's crazy.

It covers an area of ​​more than one hundred kilometers and more than two hundred miles.

The thick layer is all the words of the magic energy stone mine.

How many magic stones can be mined!

Even if they are only primary magic stones, the total number is probably an astronomical number.

Unfortunately, ...

Mo Neng stone mine is owned by the clan of the demonic clan.

Individuals ca n’t dominate.

Even if they are as strong as the Su family, they are not qualified to own a magic stone ore vein.

Looking at the cryolite spreading over the bottom of the river, exuding the coldness of the forest.

Zhu Hengyu could not help but secretly call a fluke ...

In fact, this ice crystal mine is no secret among the Demon Sheep.

Although there are not many people who know, basically, the villagers in Anping Village know.

It stands to reason that such a precious ice crystal mine should have been discovered by the Sea Serpents long ago.

But in fact, it is not so easy.

Unless the leader of the sea snake family, arrived here in person.

Otherwise, they will not be able to discover this ice crystal vein.
