Resurrection of Reiki: Get the Thunder Fruit at the beginning

three days later.

The situation is not optimistic.

Dozens of sites where open pit ore has been found have been visited.

No high black iron and magic crystal veins were found underground.

Could it be that their predictions were wrong.

According to the common sense of Blue Star's veins.

After a small amount of ore was found in the open pit.

There should be a lot of ore under the ground.

But that's clearly not the case now.

These are places where black iron and magic crystals are found in the open air.

In three days, dozens of places have been explored.

Thousands of holes were drilled, but a large number of black iron and magic crystal veins could not be detected.

The content of these substances in the soil is very low.

Ye Feihong saw the results of a new round of investigation.

Sitting helplessly on the ground.

He said to Yuan Lao: "Is there something wrong with their detection equipment? It is impossible to search for so many days without even finding a rich ore lode."

Yuan Lao: "The instrument scientific research team has tested it repeatedly, and there is no problem. I have another guess."

Ye Feihong: "You don't want to say that the race that was exterminated by the Queen of Pain has collected all the magic crystals and black iron in the underground of the entire devil's cave many years ago, right?"

Yuan Lao: "We thought of going together."

"Think about it carefully, when we entered the lair of the Queen of Pain, the metal of all the buildings inside seemed to be made of black iron."

Ye Feihong: "So, we can only have black iron and magic crystals by attacking the Queen of Pain's lair?"

Old Yuan: "Not necessarily. That kind of creature is suitable for living underground. It is impossible for the cunning rabbit to have only one nest. Otherwise, they would not be able to develop a basic civilization at all, and would have been destroyed long ago."

Hear Yuan Lao's analysis.

Ye Feihong also understood.

Ginger is really old and spicy.

Ye Feihong said: "You mean, we should change the target of our exploration, like looking for caves that might enter the underground world."

Yuan Lao: "That's what it means to me. Even if there is no black iron and magic crystal stored by the vanished race in those caves, we can still explore thousands of meters deep underground to see if the black iron and magic crystal are there. Deeper under the ground."

After discussing it, the two decided that this path was feasible.

Yuan Lao took out his quantum computer and sent a message to the City Defense Army.

Let all the reconnaissance satellites search for all possible caves.

Dozens of reconnaissance satellites in the sky immediately changed their search targets.

Dominate the three tribes from the point of view of the Mighty Eye, Queen of Pain, and Shadow.

Start in the Morden, looking for cave entrances that might go deep underground.

Numerous scientific researchers began to get busy, setting up new AI intelligent analysis solutions.

The reconnaissance satellites began to scan the environment of the Devil's Lair line by line, trying to find more valid openings.

Not every hole goes deep into the ground. Some holes look huge, but they may only be tens of meters deep, and some holes look small, but they may go thousands of meters deep.

It is obviously unrealistic to tell the depth of the hole just by looking at the size of the hole.

It is also necessary to combine the characteristics of the surrounding geological environment.

And this set of AI was not so perfect before. After all, the role of reconnaissance satellites is mainly to observe the situation of the group of beasts that pose the greatest threat to Tianmen Pass.

At the same time, Ye Feihong was not idle.

Harness the power of the mind web.

Ye Feihong explored a large number of caves within dozens of kilometers around.

Hope to find the nearest deep underground cave.

Unexpectedly, Ye Feihong actually found one, and it was not far away from them.

Only a dozen kilometers.

The speed of Ye Feihong and Yuan Lao.

Such a short distance, that is, 10 minutes.

The two quickly arrived at the cave.

The entrance is already overgrown with brambles and vines.

Apparently, the cave has been abandoned for a long time.

Yuan Lao cut through the vines with his weapon.

It's just a very small cave two meters high and three meters wide.

With such a small cave, many ferocious beasts cannot enter it.

That's why it was abandoned inside.

If the entrance to the cave was a little bigger.

Many ferocious beasts like to live in such caves.

Yuan Lao actually lit a wooden stick.

Throw it into the hole.

This is a very simple way to test for oxygen.

Inside many caves, because the air does not circulate.

The oxygen inside will be replaced by poisonous gas.

After people enter, they may not unconsciously suffocate due to lack of oxygen.

Yuan Lao asked with a smile: "Boy, I don't understand why I did this."

Yuan Laogang wanted to understand the principle behind this.

Ye Feihong took out a drone from the space ring.

There is an air detection instrument below.

Ye Feihong said: "To check the air quality, you can use this now."

Yuan Lao hadn't finished speaking, but was held back in his stomach.

He sighed and said, "Hey, I'm getting old, and the things of young people won't be used anymore."

Ye Feihong activated the drone switch.

This drone has a radar system and will automatically fly towards the interior of the cave.

At the same time, the composition in the air will be detected at any time and sent to Ye Feihong's mobile phone.

The revived world of spiritual energy did not let the technology of Dragon Kingdom regress.

This is also thanks to the fact that Long Country was the only country that controlled the production industry of Blue Star's entire technology chain before the spiritual energy recovered.

Especially in terms of drones, it was ahead of Bluestar before.

This equipment is very advanced.

After the drone is running, Ye Feihong doesn't need to control it at all.

It will go deep into the ground by itself, directly ascertaining the air content in the cave.

On the screen of Ye Feihong's mobile phone, a row of green lines were displayed.

Ye Feihong said: "Old Yuan, let's go in, the air content in this cave is normal."

Two people entered this dark cave.

Yuan Lao was about to take a torch to light up.

He saw Ye Feihong's hands waving two bolts of lightning.

Follow the walls on both sides of the cave, all the way to the depths of the cave.

In an instant, the entire cave was lit up.

Elder Yuan reluctantly put the torch he had just taken out back into the space ring again.

Xindao: Young people really know how to play.

The cave was bright, and the two walked several hundred meters along the cave.

Immediately discovered the abnormal condition of this cave.

The caves in the depths are not naturally formed.

Instead, there are obvious traces of artificial excavation.

The walls inside began to level out.

But it's a little short, the highest and lowest places are only two meters high and a small tunnel with a width of one meter.

This just proved they were in the right place.

The extinct race.

They are very short in stature, about the height of a dwarf.

Such a cave is just right for them to live in.

They accidentally discovered the place where that species used to live.

Will there be a lot of black iron and magic crystals in it?

Ye Feihong and Yuan Lao accelerated their progress. They both wanted to know whether there were the most needed materials inside this cave.
