Compared with other underground shelters, it should be more appropriate to call it the "control room" or "master control center".

The last underground building is about 200m2, and the largest area is a device in the middle that is similar to a signal transmission tower, or simply called a radar.

The facilities here surprised the three including Su Heng.

The entire building is well powered, and there is a huge console next to the radar unit.

Next to the console are two 15-inch electronic screens.

The electronic screen monitors the temperature, humidity, oxygen, air pressure, and other data related to living conditions in all shelters in the mountain.

The other electronic screen is a green screen with vertical and horizontal lines intersecting.

A variety of machines and components are piled up in the building, large and small, and it is completely a computer room.

"Your wish seems to have come true." Yan Wan said calmly.

Su Heng said before that he wanted a portable radar that could detect any creatures around him, which would greatly improve the safety of outdoor activities.

And this screen is really like the most primitive radar of the last century.

A series of question marks?

The attribute of this entry is outrageous.

"If it's radar, why is there only one dot on the screen?"

Su Heng stared at this display screen in detail.

The sentry radar he placed at the base, whether it is a person, a beast, or a robot, can be clearly displayed.

And this radar display only shows one coordinate.

There are currently three humans, one alien beast, and four robots on Wuqu Mountain.

"It's very simple, just look at which coordinate to know its functionality."

Su Heng immediately launched an experiment.

It turned out that the green dot on the radar screen would only move when Lolo was moving.

In other words, this is an instrument that can only monitor mutated genes.

Don't look at the old display screen and operating system, but the technology it contains can even be described as an exaggeration.

Just now, when Su Heng gave the robot brother outside the movement order, Xiao Hei was obviously sluggish and delayed for several seconds before executing Su Heng's order.

It can be seen that the frequency band emitted by the huge radar device in the middle is very special, and it can even affect the instructions given to the robot.

Su Heng believes that when these people made this thing, they must have made targeted technical designs.

"Then it's easy to understand."

Su Heng boldly speculated that this machine was probably created to lock the movement trajectory of the alien.

Why are the aliens afraid of Wuqu Mountain?

Probably because of the existence of this machine.

A certain part of the alien's body should be able to feel the electromagnetic waves emitted by this machine.

As long as the machine is functioning normally, it does not dare to approach, and only dares to test at the edge.

Inferring like this, many of Su Heng's previous assumptions can stand up perfectly.

According to Yin Yanyan, she has been attacked by alien beasts many times.

But the scale of each attack is not large, and it will only harass her a few times and leave quickly.

It may also be affected by this electromagnetic wave.

This device may not be an active defense facility like an electromagnetic fence, but it is like a sentry tower. As long as it enters its launch range, it will be subtly affected.

The higher the level of the alien beast, the more sensitive it will be to detect electromagnetic waves, and the greater the response will be.

Luoluo is a 3-star alien beast, but it was very active when it first went up the mountain. As time went on, it became less and less energetic, and yawned several times, and it was a little confused when walking.

This state further proves the machine's ability to influence alien beasts.

Although the function is not as comprehensive as the sentry radar, this function is not inferior to the sentry radar at all.

Being able to accurately lock alien beasts and alien creatures in units of m is simply black technology!

"Wow! Brother Xiao Su, you are so tired!"

"It's nothing great, but I have more experience."

Su Heng was able to deduce all of this because he had more experience, and he had come into contact with and seen more things than ordinary people.

In fact, as long as ordinary people stay in this computer room for a day or two, they can understand its working principle and nature of work.

Here, we have to mention a system bug.

Unowned robots can be incorporated for their own use.

But these unowned underground shelters cannot be used as their own shelters.

Possibly due to [unplaced safe house model] or balance.

So far, Yin Yanyan's basic technology is still in a very backward state.

The underground shelter does not recognize Yin Yanyan as the owner at all, she is just a 'temporary resident'.

Whether it is the basic technology or the survival score of the ladder leaderboard, this set of shelters is not recognized at all.

After walking around in the computer room, everyone also found that there was a room in the computer room that could be called a 'weapon store'.

Originally, Su Heng was still a little excited, and he was able to pick up the weapons and equipment of those advanced civilizations, but he was left empty.

Su Heng took a brief look. This arsenal should be able to store a full set of weapons and equipment for about 6 people.

Protective clothing, main battle weapons, and secondary weapons are all storage spaces for 6 people.

However, the weapon rack was empty, except for two daggers and some throwing weapons that could not be taken away.

"There is no one in the engine room, and the arsenal is empty."

"Could it be that these people went out to fight aliens, and the whole army was wiped out?"

Yan Wanxiu frowned.

"This possibility cannot be ruled out."

Facts now prove that the previous batch of human sages had already dealt with aliens.

Su Heng felt that this possibility could not be ruled out.

"It shouldn't be possible that the entire army will be wiped out. Have you forgotten the people living below?"

"I feel like they should have won, but it was a big sacrifice."

"Not only did he win the fight, but he also scared the aliens."

"But why the infighting happened later, this is not clear. Maybe only by looking for a linguistics expert and deciphering the contents of the diaries."

Yan Wan seemed to see something, so she immediately leaned down and touched the bottom of the weapon rack.

"There's another box here!"

When Su Heng heard this, his eyes suddenly lit up.

Are there any weapons you took away?

The black box hidden at the bottom of the weapon rack was so heavy that Yan Wan couldn't even pull it out with one hand. It was Su Heng who helped to drag the box out.

"What the heck, it's so heavy."

The box is rectangular in shape, two circles larger than a handbag.

Open it up and take a look.

[T-32 Transformation Grenade Launcher]

[Quality: Top class]

[Grade: Rare]

[Ammo capacity: 6]

[Function: Can launch high-explosive, smoke, lighting, tracer, impact, shock, burst, organic chemistry and other types of grenades]

The general grenade launcher is a down-mounted design located at the muzzle of the mainstream rifle, and this grenade launcher is a wheel type, which is specially used for grenades.

"These are two types of grenades. The one on the left is a high-explosive bomb, and the one on the right is marked with a skull and crossbones. It should be a chemical bomb, and it may be specially used to deal with aliens."

The 80mm muzzle is very exaggerated, and the mortars in the previous island countries were only 50mm caliber.

This also led to a series of designs, especially weight issues.

Su Heng, a big man, tried his best to pick up an unloaded grenade gun.

As for Yan Wan and Yin Yanyan, needless to say, they couldn't hold them at all.

Su Heng suddenly understood why this weapon was not taken away. It might be that even those people were too heavy to move at all. Unless his teammates took cover, it would be a target.

With this weapon, Su Heng feels that it will be much better when he kills aliens tomorrow.

"I've already figured out how to fight that alien tomorrow."

Su Heng had already made a series of plans in his heart.

Yin Yanyan has no combat experience, and expecting her to have no role in the battlefield.

Leaving aside the question of whether people are willing to go, even if she goes with Su Heng and Yan Wan, she is still carrying a medical kit and ammunition.

It's good not to mess with yourself.

"Yan Wan, you leave her the walkie-talkie, let her be behind this electronic screen tomorrow, locate us according to Lolo, and guide us remotely against the alien creature."

"Ah?? Me?"

Yin Yanyan was a little flustered.

"Brother Xiao Su, are you really going to kill that alien?"

"After listening to your description of the alien, I feel very dangerous..."

"Since it is afraid of electromagnetic waves, it will definitely hide it far away."

"If Brother Xiao Su, you really want to go, then we can make a detailed plan, so you don't have to go in such a hurry."

Su Heng shook his head.

There are systematic time-limited tasks on him.

Once the specified time is exceeded, the reward will not be available.

There is no way to mine without killing the xenomorph.

For Su Heng, 5000 Doomsday Honor Points have huge appeal and allure.

"Oh well…"

Yan Wan took off the walkie-talkie from her waist and taught her how to use it, and Su Heng began to explain in detail the battle plan for tomorrow and the backup plan.

Yin Yanyan listened carefully throughout the whole process, for fear of missing any details.

It can be seen that she still attaches great importance to Su Heng's actions.

"It's getting late, let's be here today."

After Su Heng explained everything, he also yawned.

"With so many shelters open, we can actually sleep separately and don't have to worry about privacy issues."

Su Heng suggested.

"Except for the room where people have died, the rest are fairly clean, and it's definitely fine to spend the night."

Su Heng felt that it was a bit too embarrassing to be in the same room with two women.

There are so many shelters that are empty and empty. Sleeping separately can effectively alleviate this problem. There is no need for three people to squeeze into one room, and it is not without this condition.

"Brother Xiao Su, can we not sleep separately?"

Su Heng: ? ? ?

"I am a little scared…"

Yan Wan secretly glanced at Yin Yanyan.

"What are you afraid of, didn't you sleep alone before?"

"I didn't know that aliens were so terrifying!" Yin Yanyan had a very aggrieved expression.

"And you think, Brother Xiao Su, if the other rooms have been empty for so long, there must be a lot of bacteria growing."

"If you have any skin disease or other diseases, it is very dangerous."

"When I moved out, I bought a lot of alcohol for disinfection at the exchange, and it took two days for the wind to pass before I dared to live in."

Su Heng thought about it carefully.

What Yin Yanyan said seemed to make sense.

When exploring these underground shelters, neither Su Heng nor Yan Wan wore protective measures.

If it is infected, it may have been infected in the moment of going down.

Moreover, Su Heng also has alcohol on his body, which can play a role in disinfection.

Of course, some stubborn germs cannot be ruled out.

After all, Yin Yanyan's two reasons are a bit far-fetched.

But Yan Wan changed her words and suggested that she wanted to go to the top of the mountain to see.

"Sister Yan, are you going to the top of the mountain?"

"It's so late, it's better to take a rest early. Brother Xiao Su means that when the day dawns, you're going to leave?"

Yin Yanyan did not want to take Yan Wan to the top of the mountain.

Yan Wan always felt that she was hiding something from her and Su Heng.

From the beginning, she noticed that something was wrong with Yin Yanyan, and various intuitions made her more and more worried about Yin Yanyan.

"We're leaving tomorrow, but the preparations have to be done."

"The electromagnetic wave transmitter also relies on electricity to function properly. If there is a problem with the power supply system tomorrow, then your brother Xiao Su and I may be in danger. UU reading www.uukanshu.com"

"Anyway, it's only a few steps away, and I'll get down soon without delaying my sleep time."

Yan Wan gave a reason that Yin Yanyan couldn't refuse.

All this, Su Heng saw it all.

But he remained silent.

In other words, Su Heng acquiesced to Yan Wan's approach.

He knew what Yan Wan was thinking, and she always had a slight suspicion of Yin Yanyan.

Going up to have a look may completely dispel her doubts about Yin Yanyan.

"Alright, then I'll take you up."

After walking for about ten minutes, three people and one tiger came to the top of the mountain.

The area of ​​the top of the mountain is not small, and it feels like the size of a football field.

There are standard electric energy absorption boards densely placed on it, 10 of which are in a row, a total of 100, which is the same number as Yin Yanyan said.

It is worth mentioning that these standard power absorption boards are placed at the same angle as Su Heng, which is 45°, which is the most scientific and efficient way to place them.

On the other side, there is 100m2 of standard disaster-resistant soil.

However, these soils are a bit miserable.

After a long time of abandonment, no one has planted seeds, and with the destruction of those flying beasts, only 2m2 of 100m2 can be used.

If Su Heng is not mistaken, the 2m2 planted seems to be kiwi.

The wires are connected to the inside of the mountain and directly to the power distribution box of the equipment room.

There is nothing strange, and nothing is hidden from them.

Su Heng felt that Yan Wan should feel at ease now.

"Sister Yan, I'll help you with lighting. You can check these solar panels to see if there is any problem."

"Uuuuu, the pain of art students, I knew that I chose science that year."
