"Open the door and deliver the courier!"

"The beef fried rice, green pepper fried rice, and egg fried rice you ordered are almost cold, and you haven't opened the door to get them. ”

"If you don't take it, I'll eat it myself!"

One after another, the sound came into the underground experimental base.

Inside, more than a dozen experimenters wearing ghost masks looked at each other.

"What should I do?"

"He's coming!"

"This?!"

The faces of the people were a little frightened.

On the contrary, in the iron cage, the man who was dying and had no spirit before had his eyes shining at the moment.

Du Hei and the others brought him a lot of surprises.

At first, when he heard that it was only two fifth-order junior people, he was terrified and uneasy in his heart, and he wanted to die.

In particular, when he saw a masked man, holding a fire candle, followed by the monster, he couldn't help but shudder.

He remembered it clearly.

At the beginning, when he led a team into this place to investigate.

First, he encountered a fifth-order junior opponent, who was a man with a grimace mask.

The two fought two or three moves, and they didn't know whether they won or lost.

But then, when the monster appeared, the situation changed in an instant.

's little fan sister was directly injured.

And when he was concerned about the chaos, he didn't hold on to the monster for a moment.

But after sobering up afterwards, the man also recalled slightly, he knew that even if he didn't have the slightest carelessness, he could hold on for two or three seconds at most, and he would lose.

The speed and power of the monster's impact were too terrifying.

Naturally, in this case, it is impossible not to despair.

In his thoughts, I was afraid that it would only take a few minutes before bad news came.

But the real truth was that a few minutes later, he heard a terrified chatter.

"What's going on?!"

"Oni Seven is dead?"

"In an instant, I was killed in seconds?!"

"How is that possible!"

A group of ghost-faced masked men panicked.

Naturally, they don't know what is going on in the outside world.

It's not hard to understand.

You know, what is this place?

Highland area.

Moreover, it is not only the plateau area, but also a place hundreds of miles away from the safety zone, and the safety factor is not guaranteed.

Naturally, it is impossible to pull a cable and install any surveillance camera here.

Ordinary fuel consumption, power generation, etc., are all made from iron ash ore.

And, most importantly, whether it's the people who used to mine here, or the Grimace organization that conducted experiments here in the future, they don't think there is any need to install any surveillance.

The former, who are ordinary miners, do not dare at all, let alone take away the ore in front of professionals.

The latter is that there is a formation.

Formations, perhaps, are omnipotent.

But the formation that these people have come up with is not omnipotent.

For example, the formation that exists here is a perceptual type of formation.

From the time Du Hei and Long Hao entered the vicinity of the mine, they were perceived.

However, this type of perception formation is closer to a thermal induction system.

Click, someone came in.

Well, I perceived it, the energy intensity is not low, it is a full fifth order.

Well, I perceive it, and from the scope of the existence of energy, I can judge that it is a person, and how tall it is.

But no matter how it is, you can't see things directly.

So, just now, the feedback given to them by the formation was that one of the opponents suddenly made a move, and then his companion threw out.

Immediately after that, it was hung up directly.

They didn't think it would be a monster of their own making.

After all, the monster that was brought out just now, although it was not a finished product, could still be controlled by the black fire candle.

In their imagination, the opponent knocked his companion away with a single blow, and then the residual power exploded, killing him in an instant.

Of course, if that were all there was to it, they wouldn't have been so frightened.

Researchers.

Although it is a fifth-order, it is normal that it is not usually very active, and its combat power is not high.

It's like two fat people of 200 pounds, one who often plays basketball, is always stronger than the one who stays at home.

What really scared them was.

In the perception formation, the other party only sent one person, and their ace demon was dragged down.

Even, through the energy model transmitted back by the perception formation, it can be seen that the demon's arm is broken.

One person has terrifying combat power!!

In this way, how can you not panic?

......

Du Hei didn't know that the people inside were actually afraid at this moment.

He just banged on the door and said some gibberish.

After a long time, without getting a response, Du Hei's brows furrowed.

"What are these guys doing?"

"Or is there no one in there?"

Du Hei didn't know much about the situation inside, so he could only guess whether the other party would have fled.

But on second thought, this is too unlikely.

First of all.

The other party's reaction, the grimace mask man before, but he looked full of confidence, this expression is not pretended.

And, the most important point is:

This mountain range, endless, longitudinal and horizontal, I don't know how many miles, want to open up from the other end?

The odds are slim to none.

"Looks like these guys aren't going to open the door. ”

Du Hei muttered to himself, but his gaze was extremely calm.

If you don't open the door, you think you can't help it?

Perhaps, other professionals, in the face of this situation, may really be a little helpless.

After all, attacking the iron gate may cause the mountain to collapse and bury yourself.

And it is obviously not so easy to resist the landslide.

People rely on the formation, and the internal structure is definitely more stable than the mine, after all, it can be inhabited, and the degree of stability is not bad.

Moreover, the most important thing is that depending on the formation, people can also inject energy into the formation all the time.

And when he didn't arrange the formation, he naturally could only rely on his spiritual power to protect himself.

Among them, the gap in the degree of utilization of spiritual power is large.

But as a summoner, do you need to care about that?

Du Hei sneered, turned around and walked towards the outside of the mine.

......

Du Hei's departure made everyone inside look happy.

"This guy, retreat!"

"He didn't dare to risk the mountain collapsing and forcibly break the formation here!"

"Don't be careless, though!"

"Quick, send a message to the leader!"

"Let him bring people back to help!"

"We rely on the formation and we can stick to it. ”

"Yes, maybe he'll go for support, if there's a formation mage, we'll be unstable. ”

These people began to talk nonsense.

At this time, Du Hei returned to the place where Long Hao fought with the monster before.

I saw it at a glance, looking like a dog, almost without Long Hao panting on his stomach.
