With professionals in the team, the deployment of the ruins was invisible in Liu Yuxin's eyes, and they were careful to avoid the monitoring equipment and patrols, and they came to the core of the ruins.

There was a twist in the air, and Liu Dongfa closed the invisible camouflage to reveal his figure. Reaching out and groping back and forth on a section of collapsed wall, and then his face was happy

"Found it"

Reaching out and pulling tools from his body, he removed a well-camouflaged plate from the wall, revealing a hole.

This is actually a vent disguised to the sky, and it is only thanks to an experienced reconnaissance pioneer like Liu Dongfa that it can be discovered.

"The security inside the base is a hundred times stricter than the outside, or you can only go through the ventilation duct if you don't be discovered."

Liu Dongfa smiled apologetically, the alert level of this base exceeded his expectations. Several attempts during the day were almost discovered, and he sneaked in alone so reluctantly, so he didn't have to think about taking two rookies to the front door again.

The three of them got in one after another, and at the end, Liu Dongfa restored the lid and climbed to the front to lead the way

"The design of this base is very complex, each section of the passage is effectively isolated, and the difficulty of infiltrating is almost as high as the S-level in the textbook"

Liu Dongfa, who was crawling, explained to his companions in a low voice. It has been many years since humanity stopped the civil war that it has been such a complex anti-infiltration design, and the most recent successful infiltration has been documented in the revised training syllabus more than forty years ago.

The entire ventilation duct was twisting and meandering, and after climbing for a while, Liu Yuxin had lost her sense of direction, and only knew that the machinery had to follow the two people in front of her and keep moving her own coordinates. Suddenly, Liu Dongfa stopped, and Liu Yuxin, who was caught off guard, bumped into it.

Liu Yuxin, who looked confused, was about to ask a question, but saw Liu Dongfa looking at his index finger and making a silent gesture. Liu Yuxin came to her senses and carefully moved her body back a little.

"Damn, as a third-order evolutionary, I stay in this ghost place where birds don't every day, and I really bumped into evil when I signed up here!"

"It's not the fault of this generous welfare, don't complain, you can go home and enjoy the blessings after working here for a few years"

"Say, what are we studying? Everyone who has been to the core has come back mysterious? ”

"How do I know? If you're not afraid of violating the NDA, you can ask them yourself......"

……

The conversation between the two men accompanied the footsteps from far to near, and then faded away and became inaudible.

Liu Dongfa smiled at Liu Yuxin, who kept winking at him and asked, and said in a low voice

"It seems that the secret of this base is in that so-called core area, but it should be very difficult to infiltrate. At least not by the ventilation ducts, the place should be an isolated space with another circulation system. ”

Liu Yuxin opened her mouth and couldn't give any advice, then twisted her head to Lin Feng again, and said secretly in her heart: It's time to die, right? It's time to go back! It's been such a hard day, I need to go back and catch up on my sleep! By the way, it's better to have a late-night snack or something.

Lin Feng ignored Liu Yuxin's hopeful eyes and lowered his head to think for a while

"Listening to the meaning of the two base personnel just now, it seems that there are a lot of researchers here. They should have access to the core area, maybe we can figure out a way from them"

Liu Dongfa nodded approvingly and began to lead the way again.

Liu Yuxin glanced at Lin Feng sadly and said: No wonder the handsome guy Lin is still a virgin, and he doesn't know how to pity the fragrance and cherish the jade at all! Obviously, there is such a big beauty around her, but she thinks about what researcher to find all day long, she is really blind to such a good resource.

Such an idea popped up, but it made Liu Yuxin excited:

Liu Yuxin, Liu Yuxin, is it really good for you to think like this as a big man? It can't be that the women's clothes are worn too much, and the temperament has also changed!

Although Liu Yuxin, who was extremely frightened, was extremely reluctant, he had to speed up his crawling speed to follow them, and as a road idiot, it was an impossible task for him to go home alone. Besides, Liu Yuxin is not a person who will leave his companions halfway and run alone.

After nine turns and eighteen turns, Liu Dongfa, who was moving forward, stopped again. Liu Yuxin knew that there was a situation again, so she lay down and found a comfortable position to stick to the pipe wall.

After more than ten minutes, there was a sound of the electromagnetic door opening

"Dean Su, why don't you rest?"

A male voice came up clearly through the air filter

"Well, I already have some eyebrows on this topic, let's study it for a while, you can go first"

This Dean Su should not be young, and his voice is a little old

"Then you always pay attention to your body, don't be too tired"

As the electromagnetic door closed, the whole space fell silent again

Liu Dongfa and Lin Feng glanced at each other and nodded at the same time, that's right, just choose this Dean Su.

Removing the cover lightly, several people jumped down one after another.

Feeling that there were suddenly a few more people in his office, Dean Su, who had silver hair, looked up in shock, and then continued to bury his head in the information in front of him

"You're not from this base, are you? Why break in here? ”

The tone was flat, and there was no panic at all

Liu Dongfa secretly felt sorry for Dean Su's bearing when he collapsed in Mount Tai without changing color, but things still had to be done

"We would like to ask Dean Su to take us to see the things in the core area."

"Oh? You know this? Looks like you're prepared! But I can't help it. ”

Dean Su glanced at them in surprise, and then continued to write and paint to study the topic in his hand

"Then do you know how many hurtful things these institutes have done for those things!"

Lin Feng took over the topic with a little excitement, what the Nangong family did to his captain, even if they had a big reason in hand, they didn't approve of it!

Dean Su stopped the pen in his hand and set his eyes on Lin Feng. He had also heard of rumors of various research institutes doing things to speed up their research, and the righteous indignation on the face of this handsome young man had obviously been hurt by their approach, but he was only a researcher and was powerless to change this trend

"Kid, you also have a family involved, right? Give it up as if they gave everything they had for the progress of all mankind! You must know that every great invention that advances the progress of the times will always be accompanied by the sacrifice of countless people......"

"Smack"

Liu Yuxin slapped his hands on the table with all his might, his face flushed, he was the person who couldn't stand this kind of remarks. What is the right sacrifice to be made for everyone's sake? Do the disadvantaged have to be sacrificed by the majority in defiance of their own will? What kind of bullshit is this? Shouldn't sacrifice be based on voluntariness? What is the difference between the strong and the aliens out there by forcibly sacrificing them in defiance of the will of the weak? According to that logic, isn't humanity, hated by all xenomorphs, the most deserving of sacrifice? Could it be that the death of mankind is the most correct choice for this world?

"Why are you so excited?"

Lin Feng was taken aback by Liu Yuxin's sudden frenzy, afraid that she would dare to hold Dean Su's hand tightly

Dean Su's attention was also attracted from his subject by Liu Yuxin's movements, and he looked the imposing girl up and down. When his eyes swept over Liu Yuxin's bracelet, his face suddenly changed, and then he said slowly

"Okay, if you want to go and see it, follow up! Go, find a few sets of researcher's clothes to change into."

Lin Feng's face was pleasantly surprised, why did this stubborn old man suddenly open his mind? I thought it was a tough battle...... He asked in disbelief: "Old Su, what do you mean~?"

Dean Su threw out a few sets of white coats with identification cards on them, and said impatiently

"Aren't you going down and looking? I will show you the rise and fall and the demise of mankind."

This seems like a big problem, huh?

Hearing Dean Su say this, several people present trembled in their hearts, not knowing what kind of scene they would face.

When the three of them changed their clothes and were about to go out with Dean Su

"Wait!"

Lin Feng opened his mouth to stop everyone, only to see him circle around Liu Yuxin a few times, and his brows turned into a Sichuan character

"What's wrong? I? ”

Liu Yuxin felt very strange, was there something wrong with her?

He didn't know yet, it wasn't that he was wrong, but that she was wrong.

A small man, a beautiful face, and a crisp and sweet voice. This kind of person will never forget it as long as he meets him, right? Suddenly such a beauty appeared, as long as there is even a little bit of brain capacity, people will feel strange!

At this time, Liu Dongfa also reacted, changed his invisible camouflage to Liu Yuxin, and taught him how to use it.

Liu Yuxin didn't consciously play with it, and soon mastered the use of this equipment. As soon as the equipment was activated, the light in the air was in a trance, and the whole person had disappeared.

"Hey, where's the girl? I'm not going to take you down if she's not here."

Seeing that Liu Yuxin was gone, Dean Su became anxious

"Hee-hee, I'm by your side! Can't you see it? Is it old and dizzy? ”

Liu Yuxin's laughter was heard in the air

Liu Dongfa looked at Dean Su with an apologetic look

"This optical camouflage can not only refract natural light, but also make cognitive impairment to the eyes and monitoring equipment, and can also isolate the prying eyes of various life detection devices to the greatest extent. It can be said that the person who wears this dress does not exist in this world. We were afraid that she would be too conspicuous, so we asked her to hide and follow us."

Dean Su showed a look of surprise, and then opened the electromagnetic door

"From now on, you're my research assistant, and I'll open the curfew all the way later, so you can follow closely. Remember, no matter who talks to you, don't bother with them, I'll take care of everything."

Everyone couldn't help but feel strange when they heard this, this Dean Su was too cooperative, right? actually took the initiative to take care of everything, and it seemed that we were more anxious to go down to the core area. What made him change his mind?
