Yalan looked at the screen, quickly adjusting the screen, the pictures of small windows on the screen, and said, "I'm checking the surveillance." Countless surveillance cameras are installed throughout the shelter, and these cameras, the footage they capture, will be transmitted here. As long as you check carefully, all the recent surveillance, you can find out how this woman got in, what she did, and what she took away. ”

Zhou Ziheng nodded understandingly, and no longer bothered Yalan.

Yalan's ten fingers are like butterflies through flowers, flying on the buttons, and the pictures of thirty-four small windows on the big screen are constantly switching quickly, which is dazzling.

Once the image of a woman is spotted, Yalan changes the screen and drags the window to the top of the screen. Soon, Yalan found out all the woman's whereabouts, and at the top of the screen, there was a row of small windows.

In chronological order, Yalan played the surveillance video.

The image of the woman first appeared near a vent.

It is simply unrealistic for such a huge shelter to achieve a closed circulation of water and air, and it is inevitable that when designing, how to ventilate, take water, and discharge sewage will be considered.

However, even if there is a vent, it will be filtered, purified, disinfected, and so on, and the opening will definitely be very hidden, it is impossible to find it casually. The entire passage is full of mechanisms, and it is impossible to get in easily.

The fact that the woman was able to enter through the vent showed that she knew the structure of the shelter very well, and it was likely that she had seen the full drawings.

The woman's next actions also verified this guess, because wherever she went, she did not take a detour.

The woman came in through the vent and went straight to the central control room, during which there was no trigger, no alarm device. And after every access control, the woman entered the correct password to open it, and there was no brute-force cracking of the password.

She knew the shelter as well as her own.

After the woman came to the central control room, she checked the information for a while, and then found Wang Xiaotian and them. Immediately after, the woman circled the avatars of Wang Xiaotian and Cao Lianyou, pulled them to the top of the screen, and set them with red skull markers.

Zhou Ziheng saw the woman's operation and asked puzzledly, "What is she doing?"

Arran explained, "She's putting these two kids on the top priority target for elimination, and the robot monsters, when they find them, will attack them first. ”

Wang Xiaotian and Zhou Ziheng suddenly realized, no wonder those octopus monsters would rush towards Wang Xiaotian like moths to fire.

Then, Zhou Ziheng saw that the woman came quickly to the room they had just come to.

The room was empty, only a huge box more than ten meters long, more than three meters wide, and more than two meters high, with the words "V-type non-working spaceship engine" written on it.

Zhou Ziheng saw the woman, jumping and jumping happily around the box, and couldn't help but wonder, "What is that, why is she so happy?"

Arlan immediately manipulated the console and enlarged the words on the box. On the huge screen, only "V-shaped non-working spaceship engine" remained, and a few huge words were constantly moving up and down left and right, as if Yalan was looking for something else.

"What is the spaceship engine?" Zhou Ziheng was surprised.

Yalan estimated for a moment in his heart, stopped adjusting the picture, shook his head lightly, and said, "It shouldn't be." The size of this box is too small to be a spaceship engine at all. Or, just a model for validation. Immediately check the database for any information on this. ”

Several white coats quickly pressed the buttons on the workbench and searched separately.

Yalan again looked at the box from all angles, again and again, over and over again, calculating the size of the engine inside, calculating it again and shaking his head, and then calculating it again, shaking his head again.

A few minutes later, a lab coat shouted, "Found it." ”

And then on the big screen, some, extremely complex charts and texts appeared. Yalan quickly skimmed through the charts and text, and said with great certainty: "Sure enough, it's a verification model." ”

Zhou Ziheng said: "Continue to play the video and see how she took things away." He remembered very well that when he entered the room, there were no large boxes inside. In other words, the woman should have carried the box away before he entered...... It's packed into space gear.

Surveillance footage continues to play on the big screen. Zhou Ziheng saw that on the screen, the woman put her hand on the box, and the box disappeared in an instant.

Zhou Ziheng's brows furrowed. He knew that there must be space storage equipment on the woman's body, because in the battle, he had seen the woman quickly change the net gun, and the woman did not carry the net gun.

But Zhou Ziheng didn't expect that the woman's storage equipment was so huge that it could directly fit a box more than ten meters long.

The storage equipment used by Zhou Ziheng is not so big. Moreover, this woman is obviously not a seventh-level Force Master, she can use it, such a large capacity of space storage equipment, and can also carry such a huge item at one time, which is too surprising to him.

Could it be that she is also like Cao Lianyou, with the original crystal? Or does she have a comprehension of the laws of space beyond ordinary people?

After the woman finished loading the large box, she released a spider-like machine from the storage space. She was about to jump up when she suddenly turned to look at the door.

This is, the gate was suddenly pierced by a war knife. The woman did not leave in a hurry, but took out two guns with interest and aimed them at the door. Next is the women's battle Zhou Ziheng.

Seeing this scene, Zhou Ziheng's face was a little unbearable. He is a seventh-level Force Master, and in the entire Eastern Chu Kingdom, he also belongs to the top of the combat power, the top of the pyramid, that small part.

As a result, this woman, holding two strange guns, was beaten in a mess, unable to get close and had nothing to do.

Although the people of the Purification Sect are even more unbearable to this woman, this experience has somewhat damaged his glorious image.

So, Zhou Ziheng hurriedly diverted the topic and said: "What's going on with this engine, have you found a clue?"

Yalan also felt that his face was dull, and he hurriedly switched the picture and said, "Not only this engine, but even the clues to this shelter have been found." This shelter was originally a backup base for a military-industrial complex. ”

"Wait. What is a backup base?"

"At the end of the Old Era, the world was plunged into a great war, and the flames of war burned almost every inch of the planet. All military-industrial complexes on the surface can be targets for the enemy's long-range missiles and underagents. ”

"In order to ensure the normal operation of the war machine and not be paralyzed by the destruction of the enemy, many military industrial enterprises have built factories and arranged production equipment in places close to the enterprises and in solid and hidden places, which are called backup bases. Once the enterprise is destroyed, the backup base is immediately activated to continue production. This backup base should have not had time to be put into use, and a new era explosion occurred. ”

"Oh. I see. Well, you go ahead. ”

"Ugh. Yalan sorted out the train of thought that was interrupted by Zhou Ziheng, and continued: "In addition to the equipment required for the production of the military factory, there was also a data on the newly developed spacecraft engine at that time, as well as a verification model, which was also placed in this shelter for safety. ”

"The verification model is in the box that was taken away by the woman, and the information is ...... I'll check it out. Arlan said as he typed in the command. After two minutes, Yalan sighed helplessly, "It's all taken by that woman, and it can't be recovered." ”

Zhou Ziheng thought for a while and asked tentatively: "What is this engine for?"

"Uh......" Yalan was stunned for a moment, and then remembered that Zhou Ziheng was not like them, and he was often in contact with the technology and products of the old era.

Moreover, many technologies in the old era have been lost, and many powerful products have been shrouded in the fog of history, and even evolved into items in myths and legends, and it is normal for Zhou Ziheng not to understand.

So, Arran explained: "At the end of the old era, when technology was extremely advanced, people built spaceships that could fly into the sky. It's not the kind of flight that is a seventh-level Force Master or an eighth-level Grandmaster. The kind of flight that relies on the Force has an altitude limit, and if you fly too high, you will be dizzy, temporarily unconscious, or even fall from a high altitude and fall to your death.

The spaceships developed by the people of the old era can really fly into the sky, such as to the moon, and even farther, such as Mars and Jupiter.

It is said that there is a large spaceship capable of holding millions of people and can fly to other worlds. Of course, this is just legend. ”

Zhou Ziheng listened and nodded again and again.

Arran continued: "The engine is the thing that pushes the spaceship and flies into the sky. They are so powerful that it would not be an exaggeration to say that they move mountains and reclaim the sea, and they are very sophisticated, they are covered with pipelines, and they generate a lot of heat when they work. ”

"If there is even the slightest flaw in any small place, it will affect the operation of the engine, and even destroy the entire ship. Therefore, before the formal production, a verification model will be made according to the design to see if there are flaws and loopholes in the theory and design ideas. ”

"After the model is verified, we will make further optimization based on the problems and deficiencies that have been checked, and then manufacture and verify the model, and so on until it is confirmed that there are no problems, and then the prototype will be produced. ”

"Then, the prototype is tested under various conditions to look for hidden flaws and problems. After countless times of repeated testing, improvement, and re-testing, until it is confirmed that there are no problems, it will enter official production. ”

Zhou Ziheng said with some confusion when he heard this: "In this way, what the woman took away was only a verification model, not a finished product, why is she so happy?"

Yalan said: "This is complicated to say. Because our current scientific research and industrial system have embarked on a different path. It is not the same thing as the mature and powerful scientific research and industrial system of the old era. Therefore, it is difficult for people who are not familiar with the technology of the old era to understand the scientific research and production system of the old era. ”

Zhou Ziheng was puzzled and said, "Wait a minute, what is scientific research and industrial system?"

Arran was stunned again.

Just like the teacher in the classroom who is tortured by students to the point of vomiting blood by students who always ask stupid questions, Yalan also has a feeling that a mouthful of old blood is blocked in his throat.

However, she could understand in her heart why Zhou Ziheng asked like this. This is also the reason why a mouthful of old blood is blocked in her throat and can't spurt out.

The main reason for these questions asked by Zhou Ziheng is the lack of scientific common sense in the old era.

As a mature individual of this era, his ideological concepts have been basically fixed. Many things, already as common sense, exist in his consciousness, such as the understanding and use of the Force, which is completely subconscious.

The old era was the age of technology, when it formed the basis of the whole social life, and it can be said that it is completely different from what it is now.

For example, the Force did not exist at that time, and people at that time could not understand why the Master of the Force could fly into the sky without relying on any equipment.

Of course, this scene may exist in the imagination of many people of the old era.

Therefore, with the ideas that have now been solidified, looking at the old era, there are indeed many confusing places.

It's like, let people who are used to eating peppers, tomatoes, potatoes, and sweet potatoes, people from the old era and the ancient period, travel to the middle ages of the old era, and they can't even adapt to eating.

If, let them travel through to the present, it is even more uncomfortable, and vice versa.
