"Leiton, measure the inclination and ductility of the tunnel." Ke Lan said. Although Park Sang-woo said that this tunnel can extend to more than twice the length, Ke Lan still believes in the actual measured data more.

"The inclination angle of the tunnel is twenty-eight. Five degrees, rounding is thirty degrees. The depth of our current position is about fifty meters. According to the formula, you can reach the surface by walking about one hundred meters forward." Leidon

"In addition, I used a probe to detect the strength and ductility of the tunnel... I can only say that the technology of the Alpha civilization is much stronger than ours. Two times the data may still be relatively conservative, according to me

Look, extending three to four times the length is not a problem at all. And the airtightness and heat insulation can be guaranteed. I really don’t know how they built this tunnel.”

"You mean, let's go a hundred meters further and then run to the ground?" said the hound, "Isn't that exposed?"

"Not, the premise of Leiden's algorithm is that it must be a straight rigid tunnel." Ke Lan shook his head, "I asked him to measure the inclination angle just to determine the settlement of the tunnel body in the event of severe cracking of the rock formation.

Depth and tensile stress resistance. Judging from the current situation, even if the entire ground sinks into magma, as long as the exit is still on the ground, the tunnel will be safe."

"I didn't understand." The hound shook his head, "What is the depth of settlement and stress resistance... It sounds like a noun that only those who study civil engineering will use. Have you ever had a life on the construction site before?"

"Because I am interested in the remains structure of the Alpha civilization, I have also read some books on architecture and geology... These two data are very important safety indicators in the two fields of architecture, mainly with the depth of the foundation and architecture

It is related to its own stress structure, and of course, it is also suitable for some buildings built under the surface..."

"Can you say it simple?" The Hound interrupted Ke Lan's long speech.

"It means whether the site selection and structure of the building are strong enough. The stronger the one is, the more weed it is. Isn't that straightforward enough?"

"Wouldn't you be done if you said that earlier?" The hound rolled his eyes.

"You are asking yourself..." Ke Lan made an international friendly gesture to the hunting dog speechlessly.

"Okay okay, just think I'm farting, okay?" The hound was muttering, while taking out a can of food from his backpack, "Damn it, I ran away for a day when I was hungry, nothing had happened before.

I feel that I am temporarily safe, and I realize that my belly is almost fucked to the point of my chest pressing against my back."

But when the hunting dog opened its mask, a suffocating smell of sulfur suddenly penetrated into his nose, and suddenly he choked and burst into tears. Even the can in his hand fell to the ground and rolled down the slope.

Finally, it fell into the semi-solidified magma, and a series of "hissing" sounds appeared.

"Ahem... damn... damn... damn... damn... hype... air is poisonous..."

"Isn't this a normal thing?" Layton said while chewing on the food--just the moment he opened the mask, he closed his eyes, held his breath, and quickly stuffed the food into his mouth

He closed his mask and waited until the air circulation system pulled away the toxic gas from his helmet before he dared to breathe again.

"...Cough cough...I'm careless...Cough cough..." The hunting dog coughed hard. His sense of smell was already very sensitive, and the stimulation he was naturally stronger than others.

Everyone rested on the spot for five minutes, ate some food, and then began to continue along the tunnel.

There are lighting devices in the tunnel. These lighting devices can be started with energy crystals. Only a small piece of lowest energy crystal can light up a tunnel that is dozens of meters long. Ke Lan is not stingy with this crystal.

, Every time a groove is found for energy supply, it will stuff energy crystals into it one by one.

These lighting devices are all-round and without dead corners, just like shadowless lights in the operating room, even the ground under your feet is embedded with light sources. When Ke Lan walked inside, he suddenly thought of the scene in an old movie.

The movie is called "Resident Evil", and there is a similar passage inside. The four walls of the passage are made of glass and mirrors, and light tubes are filled with up, down, left and right. At the end of the passage is a locked safety door—

—Of course, this is not the key. The most serious thing is that high-speed moving cutting lasers will be generated in the channel. This laser can even form a dense network to cover all the spaces in the channel. Those who enter the laboratory together with the protagonist

Several of the mercenaries died under this deadly laser.

Even one of the bosses was finally buried in this laser corridor.

Could it be that the Alpha civilization has similar mechanisms? Ke Lan raised her head and looked at the four walls of the tunnel. If the glass walls in the movie could still be broken, then the material strength of the tunnel was not comparable to glass.

Yes... and even if they have the ability to break the tunnel wall, there are thick rock layers outside... If they are not lucky, there may be magma that flows in backwards.

If you really encounter that kind of mechanism, you will have no place to run.

"By the way, Dr. Park Sangwoo, have you explored this tunnel several times? Have you ever walked the entire journey at one time? Are there any equipment such as institutions triggered?" Ke Lan asked Park Sangwoo with some concern.

"I've walked back and forth by myself, without any mechanism, it's very safe... If you want to say anything, there are probably only these lighting equipment..." Park Sung-woo, who was lying in the lifesaving compartment, replied, "You are worried about having it."

A trap?”

"If you don't worry about that being a purely lie, you don't know if it's a trick or something. Alfa people especially like to set up various trap mechanisms inside their own buildings, except for the lowest-level residential areas.

The more important the place is, the higher the level of danger. And tunnels like this that are not used but spend so much high-end materials must have some important role for them - you want to say that you will always

I wouldn't be surprised to install a trap every three steps." The Hound replied for Ke Lan.

"It is also possible that this is a common channel for Alpha people in mining areas... The expert team once speculated that this tunnel is likely to be a quick channel for transporting Nino alloys, just like the bridge we built on Earth and

Like highways, it is not strange to use high-end materials in infrastructure like this." Park Sang-woo said, "Military bases and laboratories may set up a large number of agencies to prevent outsiders from entering, but on a highway that needs to be accessed every day.

You won't be digging a hole, right?"

"Hey... although I'm not willing..." The hunting dog shook his neck hard, "But I have to say, these few words make a fucking sense..."

At this moment, Leiden, who was walking in the front to open the road, suddenly stopped and raised his arm: "It seems that there is something in front!"

"Is it the enemy?" The hound turned around instantly, skillfully picked up the firearm hanging on his chest, and pointed it at the tunnel directly in front of him.

"I don't know... It seems like someone lying on the ground..." Leiden said, while throwing out the drone, and galloping out with four wheels that are larger than the body, and then jumped violently.

When he got up, four blue flames ejected from the bottom and directly attached to the top wall of the tunnel.

After seeing the picture sent back by the drone, everyone breathed a sigh of relief - they were three humans who fell to the ground, life and death unknown, and the protective suits they wore were marked as the base.

"It's my own people, but they can't monitor their heartbeat, so they should be dead." said the Hound.

"Let's go and take a look." Ke Lan picked up the gun and ran towards the three corpses first.

...

The three deceased were all males, aged between 35 and 40. Based on Ivan's autopsy results and the reading of the pressure gauge that almost zeroed on the oxygen tank, we can know that the cause of death of the three people was hypoxia and asphyxiation.

I think it was because I was too hasty when I was evacuating and didn’t remember to bring enough oxygen generators.

"Looking at the outfit, it seems like the researcher at the base. Could it be that co-worker of that stick?" The hound checked the body and said.

"It's simple. Just ask Team Leader Breya to scan the facial features of these three people."

Although the faces of the three dead were severely distorted due to the pain of suffocation, the identification method adopted by the Security Bureau is mainly based on the bone structure - commonly known as "bone phase" rather than "skin phase". In this way,

Some wanted criminals can still be identified even after makeup and micro plastic surgery. Unless they have the courage to use large-scale drills on their facial bones, they can escape the facial recognition device of the security bureau.

"It was found out...the three people are Dr. Bern Ferry, an expert in aerodynamics, senior researcher at the Institute; Dr. Muller von Guderian, an expert in architecture, and an expert in archaeology of ruins.

, Intermediate Researcher of the Institute; another one is called 'Huang Renxun'. Although he is not an editor at the Institute, he is an authoritative in the field of Alpha Technology. His name was in the team that cracked the energy crystal converter back then..."

Ya Breya said.

"Good guy... any of these three people are all famous in this field. This one is called 'Borne Ferry'. She has published several times in the magazine "Aircraft" about Aircraft several times.

The paper on how to use the ship vector thruster in combination with anti-gravity device is one thing that he does have unique insights in this regard. When I transformed Valkyrie, I also referred to his design ideas... I didn't expect that they actually died.

Leighton sighed with some regret.

But before Ke Lan could say something, Park Sang-woo in the lifesaving pod suddenly started yelling: "What... Whose body did you find? I seem to... I seem to hear you talking about Muller... and Bourne

?”

"What's wrong? Do you know these people? Bourne Ferry, Muller von Guderian and Huang Renxun, we found their bodies." Leiden replied.

"What did you say?!" Park Sang-woo's reaction was like a lightning strike. "Did you confirm it is the bodies of the three of them? Didn't you admit your mistake?"

"I'm not mistaken. The work signs hanging on my chest have names and identification numbers. We also scanned their facial features and the files retained by the Security Bureau were also completely correct." Layton said.

"From the archives, Dr. Park Sangwoo and the three of them were transferred to the smelting mining area at the same time. They should have also participated in the project to restart Yaguna Kotol, and are Dr. Park Sangwoo's colleagues." Aya said on the other hand

Looking through the files, he said.

"Let me down, I want to see them with my own eyes! I don't believe it!" Park Sang-woo shouted.

"Oh... I really can't do anything to you. Are these three people having a good relationship with you? Why are you so excited?" Leiden sighed, removed the lifesaving compartment from the bracket, erected it on the ground, and let the compartment have it come to the ground.

The porthole on the door can face the three corpses lying on the ground, "Here, aren't it? Look at it yourself... By the way, have you already agreed that everyone except you have died? Why are you so responsive now?

?”

Ke Lan also looked at Park Sang-woo with some confusion. Through the porthole, he could see his facial muscles trembling constantly, as if he had seen something extremely terrifying.

He sucked for a long time before he spoke:

"They... they are indeed my colleagues... and also participants in the 'restart' project...but, but they shouldn't die here!"

"Yes, they are all rare talents. It's a pity to die here... But things have happened, and no one can revive them. You have to accept this reality." Leiden held the lifesaving pole and comforted him with kind words.

road.

"No...I don't mean it!" Park Sang-woo shouted hysterically, "They...they...they were three of the four experts who volunteered to enter the magma passage! They...how did their bodies appear here?

Woolen cloth?!"

As soon as this said, the surroundings suddenly fell into silence.

"You... are you right? Are you sure they entered the magma channel?" The hound broke the silence first, "Are you too nervous to remember the wrong place, and the magma lake No. 1 in the center of the mining area,

There are hundreds of thousands of miles apart!"

"No! I watched them get into the vehicle with my own eyes! I still remember Mueller told me before he set out that if he couldn't come back, I would ask me to help keep him in the computer. The two articles were not too late.

Post the published paper...hell! Why is he here! This is impossible! It is impossible!"

"It's not entirely impossible..." Ke Lan said suddenly, "That ancient warship has hovered over the mining area for a while, right? Did they take this opportunity to escape and come here?
