When Qin Ning spoke.

There was a loud bang outside the building.

It sounded like a cannonball exploding.

"Boom!"

There was a loud thud, as if something heavy had fallen to the ground.

Even in the maintenance department, a slight shaking of the ground can already be felt.

Seeing this, Tang Ming also knew that the situation was not good.

Although he now has more than 10,000 layers of armor on his body.

Not afraid of getting hurt.

But he still followed Qin Ning and withdrew to the subway tunnel at a very fast speed.

Not only them, but the rest of the maintenance department retreated very quickly.

There should be relevant drills in advance.

Seeing that it was safe, Tang Xiang asked Qin Ning beside him:

"What's going on? What do you mean by a fourth-level creature? ”

Retreating to the ground, Qin Ning was obviously relieved, and when he heard Tang Ming's inquiry, he immediately began to explain:

"The camp divides the mutated creatures of the wasteland into six levels."

"Level 1 is a creature that has no attack power, such as a hairy beast."

"Level 2 is something that a person can easily deal with with with a firearm."

"Level 3 requires the cooperation of a squad to kill, and Daredevil belongs to this level."

"Level 4 requires a lot of heavy firepower to cover before it can be killed."

"Level 5 is an existence that requires all the strength of the camp to solve."

"As for the sixth level.."

Qin Ning paused when he said this, and then continued: "This highest-level mutant creature is also called a serial number creature. ”

"Named in the order in which they were discovered, these ordinal creatures are all beings that cannot be solved by human beings."

"The only way to meet them is to escape."

Tang Ming nodded when he heard this, the hierarchical differentiation of the green snake was quite reasonable.

But..

"If it's just a fourth-level creature, it shouldn't be difficult to solve it with the firepower of the camp, right?"

Tang Ming was puzzled, with the Green Snake's ability to monitor the surroundings of the camp, there were fourth-level creatures approaching, and he should have discovered it a long time ago.

But looking at the situation now, it seems that the other party only noticed it after he came to the top of the camp.

"Maybe you have the ability to fly, right?"

Qin Ning heard Tang Ming's doubts, and he was also a little puzzled by this.

If it's night, the light is too dim to be able to understand the other person at the first time, but this is during the day.

"Let's see what the Legion Commander has to say later, there's no point in us guessing here."

Hearing Qin Ning say this, Tang Ming looked at the entrance.

At this moment, there are still many people rushing down from above one after another.

In addition to the paramedics, he also saw people he had never seen before.

The temperament of these people is very different from the people around them.

In addition, the speed of these people's retreat was also unhurried, and there was no nervous look on their faces.

It seems that there is no need to evacuate at all.

"These are the researchers in the camp."

Qin Ning saw Tang Ming looking at the researchers who came down from behind, and opened his mouth to introduce it.

And from his words, it is not difficult to hear the meaning of envy.

Maintenance workers like them can only be regarded as mid-level personnel in the camp, and although the pay is not bad, compared to these researchers, it is completely inadequate.

As long as you can enter the research department.

In the entire Green Snake camp, you don't have to obey anyone's orders except for those few legion commanders.

On top of that, you can also deploy your soldiers to do whatever you want.

"It's better to just start in the past than to stay in the maintenance department."

Qin Ning sighed with emotion.

There are a lot of nice girls in the camp, and most of them choose to spend the rest of their lives with the people in the research department.

To put it simply, entering the research department means that you have the right to choose a mate first, which is what Qin Ning envies the most.

"Researchers?"

Tang Ming looked at those people, his eyes flickered, maybe he could sneak into the research department to have a look.

You might be able to learn the secrets of the Stone Forest.

And just when Tang Ming was thinking like this in his heart.

Sudden change!

"Winter!"

A dull thud came from overhead.

"Boom! Rumble! Rumble! ”

The dull sound was accompanied by a violent roar.

The entire subway tunnel shook violently.

It was as if the sky was about to fall.

"What's going on up there!"

In the midst of a violent tremor, someone let out an exclamation.

And the question asked by this exclamation was quickly answered.

"Above. . . The building above collapsed. ”

The voice was a little dazed, as if he didn't expect such a situation.

"What!"

However, when they heard his answer, all the people who took refuge were stunned.

After reacting, various emotions appeared on his face.

"Good thing I ran fast enough."

I'm glad I escaped.

"How could it collapse? Isn't it just a fourth-level creature? ”

This fact cannot be accepted.

"Damn! What the hell are those soldiers doing! ”

Angry.

But the people who have sadness on their faces are the majority.

Either they have friends or relatives, but they can't evacuate.

The noise overhead, after the collapse of the building, quickly returned to calm.

The battle came and ended quickly.

"Medic! Medic! ”

Soon a green snake soldier came and shouted:

"And you, too, go up with me to save people."

With that, the soldier hurried away, as if someone else was going to inform him.

"Let's hurry up."

Seeing this, Qin Ning hurriedly opened his mouth and said to Tang Ming.

Hearing this, Tang Ming didn't say anything, and as the crowd quickly walked out from the subway entrance on the other side, which had not yet collapsed.

Only the tech building they were in was attacked.

At this moment, this science and technology building has become a ruin.

And under the cover of this ruin, a mutated creature with a huge body can be faintly seen.

This should be the fourth-level creature that attacked the Green Snake camp, but since its body was completely covered by masonry, it was impossible to see what kind it was.

While Tang Ming was looking at these, the rescue operation had already begun.

The hundreds of people who came out of the subway tunnel, with the cooperation of the surrounding Green Snake soldiers, began to carry bricks and stones, looking for those who might still survive.

After Tang Ming glanced at it, he also stepped forward to help.

However, he was looking for the ruins of the first few floors of the tech building.

I hope to save people and find some valuable items at the same time.

He has a lot of strength, and most of the bricks and stones can be moved by him at will.

He soon found some broken bottles and cans.

It contained the tissues of some mutated creatures, but they were all shattered at the moment.

Obviously, it was impossible to see what the Green Snake was trying to do when he was studying these things.

Tang Ming continued to search, except for those unknown biological tissues, but he really let him find two researchers.

These two people probably felt that there was no threat to the fourth-level creatures, so they didn't even run away and chose to continue experimenting in the laboratory.

It's like a person who has encountered a magnitude four or five earthquake, and feels that there is no need to escape from this tremor.

And for not cherishing their lives, these two people also paid the corresponding price.

One fell into a permanent sleep, and the other lost both legs.

"Huh? Still have kids here? ”

After rummaging for a while, Tang Ming was stunned.

A little boy of eight or nine years old, with silver hair and a bandage around his body, was dug out of the rubble by him.

Tang Ming, who originally wondered why there were children here, instantly realized after seeing the bandages on the other party's body.

This is probably some of the Green Snake's legion commanders he doesn't know.
