Wolf Warrior and the others subconsciously raised their guns and aimed them at the door.

Correspondingly, dozens of soldiers on Zhao Yu's side also reflexively raised their guns at them.

The wolf warrior suddenly sweated on his forehead, and said with a little nervousness: "Who are you?!" ”

The other five survivors, who were still a little elated, couldn't help but panic when they saw this scene and squatted down in the corner again.

The thin monkey was also a little nervous, although Zhao Yu said that they were residents of the neighborhood, but he didn't know what the other party's real purpose was.

He turned his head to look at Zhao Yu, "Zhao Baichang ......"

Zhao Yu glanced at him, looked at Wolf Warrior and the others, and repeated what he had said before, saying: "We are residents of the neighborhood, and there are survivors who have escaped from here, saying that there are monsters here, so let's take a look at the situation, and by the way, see if we can save people out......"

Residents of the neighborhood?!

The wolf looked left and right, looking at the warriors who were heavily armed and had resolute faces, and only felt ridiculous.

But he didn't dare to believe it, "I see, we are from the Rizhao Group, and we heard that Vault 12988 was missing, so we came to see the situation......

Rizhao Group!

Zhao Yu thought to himself, this alien in the refuge, I am afraid that they released it.

But he didn't embarrass the soldiers, after all, they had no decision-making power, and it seemed that the squad was clearly being used as cannon fodder.

"yes, it looks dangerous here, my people were killed by monsters just now......"

Zhao Yu nodded, saw that there seemed to be a few people hidden in the room, and asked, "How many people are there among you?!" ”

"There are also a few residents of the shelter......" Wolf Warrior gave up, revealing the five survivors hiding in the corner.

These five survivors didn't know that the strongest force at the moment was Zhao Yu and the others, and they got up uneasily.

Zhao Yu, like the wolf warrior and the others before, inquired about the situation in the shelter for the five people.

The results were consistent with his suspicions, a few days ago there had been a mutation, a monster had appeared, and the time was comparable to his departure from the chemical plant.

"Understood, since that's the case, then I'll send you out first!"

The five of them were ecstatic and hurriedly expressed their gratitude.

Wolf Warrior and the others were a little dazed, they were also warriors, and they came out on a mission this time.

"Head, we're going back like this?!" Fire Chili asked in a low voice.

The wolf warrior glanced at his teammates who were still lying in the hall at the moment, gritted his teeth and said, "Go back, the mission failed......"

On this trip, they lost half of their manpower.

People of Rizhao Group......

Zhao Yu thought about it for a while, and then decided to let go of Wolf Warrior and the others.

After all, there were five survivors with them, and there was no way he would kill people in order to prevent the news from his side from getting out.

Moreover, the quest mentions that he will be rewarded with 5 tech points for each person rescued, which is what he lacks the most right now.

"Then let's go, I'll send you out first, and then I'll rescue the others......"

Soon, the ten survivors gathered together and were arranged by Zhao Yu to the center of the team.

The five survivors looked at the so many soldiers on the periphery, and they were suddenly full of security, and their eyes looking at Zhao Yu were full of gratitude.

"Zhao Baichang, I don't know what the force you belong to is...... After we went out, we wanted to go to your place to thank ......"

Power......

Zhao Yu thought about it, he didn't seem to have named the force yet, and every time he said that the nearby residents didn't seem to be reliable.

suddenly came up with a name, but he couldn't think of it, so he simply gave it a similar and simple name like Meng Xian.

"We are ...... in Zhaojiazhuang"

"Zhaojiazhuang?!"

Several people looked at each other, but they couldn't tell whether it was true or not, after all, they were all isolated survivors of the shelter.

"Zhao Baichang, thank you this time, after we go out, we will definitely find an opportunity to go to Zhaojiazhuang to repay your life-saving kindness......"

Zhaojiazhuang sounds like an ordinary gathering place for survivors.

Zhao Yu had previously heard from the survivors that after the end of the world, the forces in the wilderness were basically arranged in order of scale and strength, villages, villages, villages, and towns.

A set of names was formed for spontaneous judgment of the size of the force.

Of course, there were also weak organizations that claimed to be the town in vain, and later caused the owner of the village surnamed Xu to be dissatisfied, and said "What grade are you" and directly sent troops to destroy it.

Since then, there has been no corresponding strength, and few of the various gathering places dare to name across strengths.

Zhuangzi is very good, it will not attract the attention of the village, and it is stronger than the power of the village.

Zhaojiazhuang?!

The wolf warrior and the red pepper looked at each other, they have been to this place a few times, and they have never heard of a Zhaojiazhuang.

It is suspected that Zhao Yu is talking nonsense, and they may be people from some big force.

The wolf warrior followed the team, but his eyes kept looking at the soldiers around him.

Especially the tall and strong Menghu beside Zhao Yu.

After observing for a while, his brow furrowed, and from what he could see, these soldiers were disciplined and meticulous in carrying out their tasks.

There was no superfluous word, and the movements were not deformed because no one noticed, and he always maintained a military posture and walked and stood.

This kind of attitude is not at all something that a mere Zhaojiazhuang can afford!

Could they be the people of the Reed Group?!

Wolf Warrior felt that only the Reed Group, which was also one of the three major groups, was qualified and had the strength to train so many soldiers.

"Ascend Pedal ~"

Just then, there was another sound in the exhaust pipe.

"Stop!"

Zhao Yu immediately gave the order and made the entire team stop.

The ten survivors suddenly came to their senses and stood still, not daring to move.

The wolf warrior no longer speculated about Zhao Yu's background at this moment, and followed the others, raised his head, stared at the exhaust pipe above his head, and listened to the movements of the alien.

"Dangdang!"

The sound in the exhaust duct came from far and near, and everyone became nervous.

Zhao Yu also slowly raised his hand, as long as his hand fell, the soldiers would get the signal and shoot as soon as possible.

But just as he was about to reach the farthest head of the soldier, the sound stopped abruptly.

There was a sudden silence in the shelter.

Everyone didn't dare to gasp and stared nervously at the top of their heads.

"Shop around~~!"

At this time, movement sounded again in another direction, which immediately diverted everyone's attention.

"Another head?!"

Zhao Yu frowned slightly, is this the alien using the strategy of striking the east and the west?!

As depicted in the film, Xenomorphs are very hunter-gathering, often able to launch sneak attacks from angles that humans don't expect.

In reality, not long ago, they encountered an alien.

At that time, there was a noise in the pipe, and they all thought it was an alien, but it turned out to be a thin monkey.

Judging from the condition of the alien walking through the exhaust pipe, it seems that there is no reason for the skinny monkey to stay in it for so long and still be safe.

If you think about it in the worst-case direction, the reason why the thin monkey is safe is likely to be intentional by the alien.

They know that there are more living people down there, and they want the skinny monkey to attract the attention of others.

What do aliens rely on to distinguish their prey?

According to the movie description, there are many types of aliens, some have eyes, some have no eyes.

Some rely on heat to sense their prey, while others rely on hearing and sight.

However, most of the xenomorphs rely on pheromones, which can sense secretions specific to other organisms.

To put it simply, it is to distinguish the location of prey by smell.

More advanced, Xenomorphs can even judge the mental state and emotions of their prey.

For example, whether the prey is afraid, afraid or even excited, can sense and make corresponding judgments.

"Climb and kick~~~!"

The alien on the other end, the voice also slowly approached from a distance, and disappeared again when it was about to reach the top of the soldier's head.

The invisible pressure enveloped them, and the ten survivors in the middle area were sweating profusely, and their faces were full of fear.

Even the well-trained Wolf Warrior and others were no exception, staring nervously at the ceiling with guns in both hands.

If Zhao Yu hadn't said in advance that they wouldn't do anything after the war, someone might have been unable to help but shoot.

Looking at their reactions, Zhao Yu understood that these aliens were indeed quite smart, they were natural hunters, and they were much stronger than other monsters.

But he didn't panic, his soldiers were robots, and they didn't know what fear was.

This may be the reason why the aliens have been slow to attack, they can't figure out what the soldiers are.

"Dangdang~~!"

There was a rattle in the exhaust pipe in the third direction.

The ten survivors in the field felt that their breathing was about to stop, and several of them turned pale and their holes were enlarged, as if they were suffering from something.

"Don't worry!"

Seeing this, Zhao Yu knew that they had reached the limit of fear, and hurriedly spoke out to reassure.

"If they are strong enough, they can fight head-on, and it is precisely because they know that they can't beat us, so they will engage in these tactical strategies......

After Zhao Yu said this, everyone's nervous demeanor relaxed slightly.

But Wolf Warrior and the others are a little dazed, and the monster still knows tactics and strategies?!

They don't understand, but they shake with big hands.

But right now, what Zhao Yu said seems to be true, otherwise why didn't the monster attack for a long time, but kept making noises and affecting everyone's emotions?!

"Bang~~!" "Bang~" "Bang! ”

In the distance, a burst of gunfire rang out, and everyone was startled.

Zhao Yu turned his head to see that the soldiers over there had automatically triggered the attack command and launched an attack on the unknown creature.

"Stay here, I'll take a look!"

After Zhao Yu left the next sentence, he quickly led people to rush over there.

Several survivors took a look at the soldiers around them and were relieved to see that they were not moving.

The wolf hesitated for a moment and followed.

Seeing this, Huo Chili was worried that the wolf warrior alone would cause a misunderstanding, so he immediately followed.

After all, she is a woman, and in this case, she can also clear up some misunderstandings of Zhao Yu.

Soon, the group arrived at the scene.

In this room, seven or eight soldiers were forming a circle, firing incessantly into the middle.

"Zizizi~~~!"

In addition to the sound of gunfire, there was a strange sound at the scene.

This sound made the wolf warrior and the red pepper a little stunned, could it be that this monster's cry is like this?!

But then he discovered the truth.

The sizzling sound was not the cry of a monster at all, but the sound of the monster's blood corroding against the ground.

"Killed?!" Red Chili pepper asked, slightly nervous.

Zhao Yu got a little closer, and when he saw the alien corpse lying on the ground and no longer moving, he nodded and said, "Kill it!" ”

Wolf Warrior and Red Pepper glanced at each other, and there was a thrill of revenge in their eyes.

The two of them hurriedly stepped forward to check.

In the middle of the scene, a huge monster with its head beaten to slag was lying in a pit where the ground was mostly corroded and some of it had collapsed.

On the monster's tail, there is also a soldier who has been stabbed through the body.

"He ......"

Red Hot Chili pepper's eyes widened, a little incredulous.

She noticed that the soldier had a rope around his waist and the other end wrapped around the monster's tail.

The wolf warrior also saw this scene, and his face became solemn.

So far, he still doesn't know what happened to the success of this hunt.

Obviously, it was the soldier who sacrificed his life to forcibly drag the monster that attacked him, which gave the other soldiers a chance to attack and kill.

At the same time, he finally realized what these soldiers were doing with ropes wrapped around their bodies!

They came here with the determination to die!

The wolf couldn't help but be in awe, folded his legs, straightened his body, and saluted seriously.

Seeing this, Huo Chili also saluted, for them fighters, such a soldier is really worthy of their respect.

Zhao Yu squatted next to the alien, and there was no system prompt in his mind, which indicated that there were other aliens in the shelter.

Wait a minute!

The wolf suddenly realized that since these people had ropes wrapped around their waists, didn't it mean that they already knew the information of this kind of monster?

And also made a corresponding battle plan based on this?!

If that's the case, then could this monster be created by them?!

In the last few years, he had never seen this kind of monster before, and it was obviously a new type of monster.

With the background of Zhao Yu and the others who seem to be the Reed Group, this monster is likely to be developed by them!

Thinking about it like this, he couldn't help but feel shocked, only to think that the Reed Group might be doing a stupid thing to bring humanity to extinction.

After all, these monsters are strategic and tactical, and with their intelligence, they may evolve to an even more terrifying level.

The world is getting more and more chaotic!

"Pack up and take them out......"

The alien corpse, Zhao Yu doesn't plan to let it go, this is a special flesh and blood, although the corresponding class has not yet appeared, but the future is promising, and it can be kept in reserve.

When he came out this time, knowing that it was to deal with aliens, Zhao Yu made preparations in advance.

Alien blood is corrosive, a molecular acid, and there are many ways to prevent it from being corrosive.

Glass, ceramic or silicate materials, as well as some inactive metals or metals that do not react with sulfuric acid.

However, before that, Zhao Yu needed to see how acidic the blood of this alien was.

The alien that I killed last time didn't think about researching it, and sent it directly to the recovery furnace.

Zhao Yu took a piece of dead wood from a soldier's hand and slowly inserted it into the blood flowing outside the alien.

"Zizi~~!"

Amazingly, even metal can corrode the blood of a large pit, and when it hits wood, the corrosion is very weak.

"Preference for dilute sulfuric acid ......"

Zhao Yu took out the wood and took a look, except for some blackening, the overall structure was complete.

He nodded slightly, but he could understand that concentrated sulfuric acid can be dehydrated and oxidized, and it can turn the host into a dry corpse in the alien body, so the blood in its body is dilute sulfuric acid.

Zhao Yu got up and beckoned to a soldier in the distance, "Take out the things!" ”

Soon, the soldier took out a pile of bottles and cans, all of which were glass.

Shaped blood is corrosive and is ultimately an inorganic compound that can be decomposed into an industrial raw material.

It can be used in a wide range of ways, such as fertilizers, such as medicines, pigments, batteries, and so on.

But for Zhao Yu, the most important thing about this sulfuric acid is that it can be broken down into the compounds needed for explosives.

At the moment, the resource recovery plant has not yet been established, and it is a bit of a waste to throw it directly into the arsenal, so Zhao Yu wants to collect some alien blood first and wait for the resource recovery plant to be completed.

When the time comes, the resources will not be wasted, and some ammunition will be replenished.

It will take a little time for the blood to flow cleanly, Zhao Yu naturally won't let everyone waste here, and after handing over the collection work to a few soldiers, he will lead the team on the road again.

The rest of the survivors, as they passed by the corpses, were equally shocked to see the soldiers tying the monster with ropes.

"See the rope on them?"

"I didn't expect them to be willing to sacrifice themselves in order to kill monsters......"

"No, I mean, all the soldiers present seem to be ready to sacrifice themselves, except for the leader!"

Everyone was shocked, and they just thought that this group of soldiers was different from the others they had seen.

Even a few of Wolf Warrior's teammates were the same, asking themselves, would they be willing to let them tie the rope like this, ready to sacrifice at any time?!

Perhaps, it takes a little courage!

Fire Chili sighed, she didn't want to die, maybe she would choose to die with the alien when she was going to die.

The rest of the road was surprisingly easy, and there were no new alien attacks.

When he came to the mouth of the patio, Zhao Yu flashed his flashlight up a few times, and got a response from the soldiers on the ground, so he turned his head and said, "It's okay, you can go up!" ”

There are a lot of flashlights, and the patio is illuminated, so you can be sure that there are no aliens lurking here.

Soon, at the urging of Zhao Yu, ten survivors climbed up along the rope one after another.

When they completely left the patio and returned to the ground, Zhao Yu also received a prompt from the system.

[Rescue 10 survivors and reward 50 technology points.] 】

"Cool!"

Zhao Yu's face was ecstatic, this mission was worth it, this has not been completed, so he gave 50 technology points first, which is equivalent to the daily task of the previous day.

Although two mobilized soldiers were sacrificed, it was not worth mentioning compared to the harvest.

According to his assumption, even if five mobilized soldiers are exchanged for one survivor, after all, what he lacks most at the moment is science and technology, but other material resources, which are enough for the time being.

Zhao Yu didn't linger near the patio, and said excitedly: "All of them, continue to go deeper, rescue the survivors!" ”
