"Dark Aura...... Is it really something that needs to be mined to get it? Lu Yao's heart was shocked inexplicably.

If the development location of the Dark Aura is the same as the mine, then how many Dark Demons will be born around that mine? If the dark aura spreads out, how many living beings will be destroyed?

Lu Yao couldn't imagine it.

"As I said before, dark aura is not an invention in the sky, but a discovery." An Yun looked at Lu Yao's surprised expression and explained softly.

"Although I don't mean to excuse the Sky Society, the fact is that even if there is no Sky Society, there will be the Earth Society, the Fire Society, or some other force, or even the official discovery of this substance.

Regardless of who it falls into, experiments on the production of dark demons will be carried out. After all...... It's the perfect biological weapon. ”

Lu Yao took a deep breath and nodded heavily: "I understand, Sister An Yun, but at the very least, I still hope that a place like the Dark Aura Mine can be firmly controlled by an organization like Shengjing University."

So, what do we need to do to be able to lock down the location of that mine? ”

An Yun pressed her chin and pondered for a long time before saying, "Show me the location map of all the strongholds of the Sky Society." ”

Lu Yao didn't dare to slack off, and hurriedly called up the locations of the more than twenty cities with Sky Society strongholds from his mobile phone and handed them to An Yun.

The latter zoomed out the map and said, "You two come and see." ”

Hearing this, Lu Yao and An Ran leaned over left and right, looking at the map on the screen curiously.

"If you look closely, do these more than 20 cities, as well as the location of the two headquarters, span several provinces and form an irregular circle?"

Lu Yao and An Ran looked at each other, just this distribution location, is it too hasty to say that it is a circle?

"Don't worry about the irregular rules of this circle, what you need to see is the center of this circle." An Yun raised her hand and knocked one of the two people next to her on the head.

After An Yun mentioned it, the two of them suddenly came to their senses, and when they looked closely, they found that between these cities was a huge mountain range.

When they didn't know that there was a concept of a dark aura mining area, they naturally ignored the existence of this mountain range, after all, no city was built on this mountain range, and they couldn't let the sky build a stronghold in the mountain and go into the mountains to be a wild man.

However, when the concept of the Dark Aura Mining Area was learned, the mountain range became extremely suspicious, and the sky might have a stronghold inside.

The Dark Aura Mine is not something that can be found in downtown areas, it must be located in the wilderness, so its location can eliminate all the cities where the Sky Guild is located in one go.

And the Dark Aura Mine is the basic disk of the Sky Society, and their stronghold must not be too far away from the mining area, since this is the case, it is obvious that there is a problem in this mountain range.

"However, even if we can lock the location in this mountain range, the scope is still a bit large, and it will take at least a month or two to search it thoroughly.

With such a long buffer time, the people of the Sky Club must have already made arrangements. Lu Yao raised another difficulty.

He suddenly found that in terms of IQ and brains, he and An Ran combined were not as good as An Yun, who had been bedridden for nearly three years and could still analyze everything in the outside world.

It should be said that it is worthy of the specialized ability of the brain.

"If you want to lock down the Dark Aura Mine more precisely, it's up to you to do so." An Yun said with a smile.

Lu Yao hurriedly said: "Please give Sister An Yun some advice." ”

"Actually, it's just a stupid solution, according to what you said, among the small strongholds you have destroyed, there are dark aura, dark demons, and the existence of researchers.

In other words, these strongholds have a certain connection with the dark aura mining area, and at least there is a team responsible for receiving the dark aura energy. After all, it is impossible to transfer the mined dark aura to the headquarters first, and then the headquarters will distribute it to the branches one by one.

Some branches are thousands of kilometers away from the headquarters, which is completely cost-effective. It is far less convenient for each branch to go to the joint location on the mountain to pick up the goods.

Starting from the researcher who took over the dark aura, to the minions who carried the dark aura, to the person in charge of managing the dark aura...... If you go through this trial layer by layer, there is a high probability that you will be able to find that joint team and develop this team into a leading party, which will save you 95% of the search time. An Yun explained.

After hearing this, Lu Yao slapped his palm, almost clapped his palm, and muttered: "This method is definitely feasible!" Sister An Yun, you are simply a genius! ”

An Yun smiled, a little proud.

She looked at Lu Yao who couldn't wait, but was embarrassed to go, and said reasonably: "Go and implement this plan, don't be polite, I just have An Ran with me here." ”

Hearing this, Lu Yao scratched his head a little embarrassed, and said embarrassedly: "Sister An Yun, I'm really sorry, after I'm done, I will definitely accompany you with An Ran." ”

"Go quickly, if you can really completely wipe out the sky, it will be the best gift for me and An Ran." An Yun smiled and waved her hand.

Lu Yao nodded heavily, turned his head and walked towards the vice principal's office.

In the office, Lu Yao quickly explained the situation to the two vice principals.

After the two of them got this information, they also had a sense of sudden enlightenment, and the three of them took direct action, went to the place where the prisoners of the Sky Society were detained, interrogated one by one, followed the vine, and got to the bottom of it, and sure enough, from the group of captives, they found three teams of capable people who connected with the Dark Spiritual Qi mining area.

After interrogating all the team members separately, the results were basically the same, they all received the mined dark aura from the meeting point somewhere in the mountain range in the area called the Gua Mountains.

After getting the news, the three of them were extremely excited, and immediately began to gather the team covertly, Jiang Lan led the team, led a team of perceptual ability, and then brought the Lu Yao team and the other two B-level combat teams, and bet on the captains of the three Sky Junction teams, a total of twenty-one people. I left on time an hour after the mission was announced.

As soon as night fell, the team from Shengjing University descended into the Gua Mountains.

This mountain range stretches endlessly, and in the light of the moon, it is like a creeping beast, if there are ordinary people who are lost in it, they will never think of it in this life.

The only thing that is friendly to humans is that this mountain range miraculously does not have A-class demon beasts, and everyone used to think that it was because the Gua Mountain Range was too close to human cities, so A-class demon beasts avoided it.

But now it seems that this strange phenomenon may have something to do with the Dark Aura Mining Area.

It is precisely because there are no A-level demon beasts here, even at night, Lu Yao and the others can walk sideways.

They asked the three Sky Society team leaders to point out their joint locations, and after some tossing and recording, Jiang Lan and the others found that the joint locations that these three people went to were completely different, although they were on the same mountain, but their directions were completely different.

However, this was not difficult for the people of Shengjing University, and after analyzing the three joint locations, they pulled them into a straight line, locked the point where the three lines intersected, and decided to start the search from there.

Just like the twenty-odd cities with strongholds of the Sky Guild, the joints they extend out of are also revolving around the exact location of the Dark Aura Mine.

After squeezing out all the value of the three squad leaders, Lu Yao knocked them out one by one and threw them into the exclusive space.

Then, under the leadership of Jiang Lan, the four teams from Shengjing University came to the locked position non-stop, and the five professional perception people were full of firepower, probing everything within a radius of more than ten kilometers.

It only took about an hour, and one of the perceivers said, "Report, I sensed the presence of the aura of the capable person, ten kilometers due west. ”

"Okay, one of the perception team will continue to investigate, and the other four will rest for a while." Jiang Lan wanted to cheer twice excitedly, but because there were so many juniors around to watch, she was embarrassed, so she had to command with a straight face.

"Yes." The perception team consulted among themselves, and selected four people who needed to rest.

"Everyone else, cheer me up, today's surprise attack must be fast, accurate, and ruthless! Biting this mining area off the Sky Society at once, you can't give them a chance to react! Jiang Lan said in a deep voice, "Get ready, just follow me!" ”

"Yes!" The crowd replied with their voices suppressed.

Then, under the guidance of the perceptual person, Jiang Lan led the team, followed by Lu Yao and An Ran, and behind him were the most elite teams of the entire academy, a total of twenty-one people, silently, daring to go towards the direction of the suspected dark aura mining area.

"More and more capable people are appearing, and it can be determined that it is a large stronghold of lawless forces!" As the distance approaches. The Sentient discovered more information.

"Okay, keep looking." Jiang Lan encouraged.

Suddenly, the perceptual person's face turned pale: "In that stronghold, a large number of chaotic and tyrannical energy substances have appeared, which is extremely dangerous!" ”

"It's crazy to have a stronghold right next to the mine." Jiang Lan ordered everyone to stop first and glanced at Lu Yao.

Lu Yao understood, took out protective clothing directly from the exclusive space, and distributed it to everyone.

These protective suits, all based on the protective clothing worn by researchers who study dark aura, are not only more airtight, more tenacious materials, but also independent gas cylinders, which can minimize the possibility of being infected by dark aura.

After everyone changed into protective clothing, they continued to act.

Soon, quietly, I touched the edge of the Sky Meeting stronghold.

Here, I haven't seen anything yet, but I can already hear a deafening roar of inhumanity.

Five Generations of Rivers, Mountains and Moons

It was the roar of the Dark Demon.

"I'm afraid, this mine is an experimental field that is even bigger than the second headquarters of the Sky Society!" An Ran said softly.

In the second headquarters of Anzhou City, the scale is still a little too small, and it is still in the city, so how can it be fast and convenient to use local materials?

"It looks like there's a tough battle to be fought today. However, if we don't have an A-level powerhouse, we definitely won't lose! Lu Yao smiled.

This is not conceited, but based on the judgment of their existing strength, their lineup this time is too luxurious, counting him and An Ran, there are three B-level peak combat power, and it is not an exaggeration to say that his combat power is more than the vast majority of B-level peaks, such as the two vice masters of the Sky Society, he has no big problem alone.

In this mine, there may be strong people, but can there be more strong people in the two headquarters of the Sky Society combined? Or will there be a hidden A-class in the sky? This is impossible, the birth of every A-level powerhouse will cause a sensation, and it can't be hidden!

Therefore, the only thing to guard against is an unknown number of Dark Demons.

"Lu Yao, get rid of the sentry of this stronghold!" After seeing a wall more than ten meters high, and the group of guards on the wall, Jiang Lan commanded.

Lu Yao nodded lightly, asked the perceptual person about the location of all the guards, and after confirming that nothing was missed, he summoned a silver-blooded small sword.

In the moonless night, this small sword with the length of a finger looms, and if you don't look closely, you won't notice it at all.

As soon as Lu Yao's mind moved, dozens of silver-blooded swords shot out silently, heading towards the guards on the wall.

Almost at the same time, a slight, but extremely slight cutting sound sounded.

Then I saw that all the guards on the wall were all clutched and fell down.

When they were halfway down, Lu Yao also thoughtfully supported their bodies with a silver-blooded little sword and slowly lowered them to the ground, so that they didn't even make the sound of falling to the ground.

The only sound, only the faint sound of blood dripping.

A large amount of potential upgrade points are credited to the account, to be honest, the strength of these guards is not bad, and all of them are C-level, but unfortunately, in the case of defenselessness, they can only end up being killed by Lu Yao in seconds.

It's not that they're weak, it's that Lu Yao's hands are too dark.

Except for Jiang Lan and everyone in Lu Yao's team, everyone else looked at Lu Yao in surprise.

For this young genius who had made a name for himself, they had only heard that he had divine blood, so he could match the powerhouses of the peak of the B rank when he first entered the B rank.

In this regard, in fact, some people are not convinced, after all, the effect of divine blood is the same for everyone, and this junior brother named Lu Yao just happened to have shit luck.

But looking at it with your own eyes, the truth is that even without the blood of the Ancestor of the Gods, this sword technique alone is enough to kill most of the people present.

And this junior brother Lu Yao is even a multi-capable person! This strength may only be a fraction of his overall strength.

It's scary.

"Dive in!" Jiang Lan gave an order, and everyone immediately took action, for them, the ten-meter wall was almost equivalent to flat ground, and they could cross it with their legs.

It seems that for fear of being counter-detected, there is no modern reconnaissance equipment installed here, so their infiltration operation this time is extremely smooth.

After entering the wall, everyone saw a somewhat gloomy looking mountain town. This is where the miners of the Sky Society live.

Jiang Lan lowered her voice and said: "The people who live in this mining area, they all have great value, we try to take the method of capturing alive, the soldiers are divided into two ways, one household by one to search, after being knocked unconscious, they will be controlled, and they will be sent to Lu Yao's exclusive space." ”

"Yes!"
