The two chatted and unknowingly arrived at the door of the last room. There was only one entrance to the external interaction, which was the secret room of the entire tower.

After using his own authority to open the room door, Lai took Qu Xiao into it. The structure inside the room showed circuits everywhere, which looked quite complicated and chaotic.

However, this room is still very well protected by the internal machines. Even the circuits exposed outside are not damaged or failed due to the passage of time. The air pressure inside the room is very tight. The moment the two of them opened the door, they could even hear the movement of pressure relief. kano ん 5

Qu Xiao also heard a similar sound when he first entered the gate. This made him understand why the things in this building were preserved so well.

It seems that the designers who designed this building have long considered the issue of "preserving internal resources". In order to greatly extend the retention integrity of the internal resources of this building, they specially designed some things to create vacuum environments.

Although this design is not foolproof from the current situation, it has indeed delayed the damage to the internal resources of the tower to a large extent. If it were not for such a design, everything that everyone sees now would probably be corrupted into colloidal black mud like the substances outside.

Walking to the center of the room, there is an electronic terminal that can control the mysterious device at the bottom of the tower. Because there are currently two crystal human-faced beasts that continue to supply electricity, there is no difficulty in starting the electronic terminal.

After verifying his identity, Lai was allowed to enter the second-level operation interface. Qu Xiao was a little puzzled when he saw this. Compared with this big machine that looked very extraordinary, this verification seemed a bit sloppy.

"This way it's ready to use?"

"Yes." Lai turned his head and looked at him, "Does it be in your impression that if you start a program, do something else to do?"

"It's not that in my impression... I just feel that this thing looks very advanced, and just use the permissions to activate it. I always feel like something is missing..."

"Your feeling is not wrong." Lai smiled, "This was in the pre-world period, so verification was naturally not that simple. However, at that time, the building suddenly entered an emergency blockade, so to activate this thing, you only need to reactivate its active use permissions."

"What do you mean is that this thing has always been verified and passed?" Qu Xiao was a little surprised. "As long as the emergency blockade of this building is lifted, can it be used directly?"

"It can be understood so."

"Then you just need to swipe the permissions to lift the emergency blockade?!"

"To be precise, as long as people at level 2 or above are not granted access to the building, as long as they can find a way to enter here, they can still use their own identity permission to lift the emergency blockade of the building."

Lai explained, "In other words, although this device was secret in the previous era, it was easily accessible to outsiders in this era. Do you still remember what I talked to you when I was outside just now? In addition to us, there should be outsiders in this place."

"So their purpose here is also for this device?"

"I don't know, but probably... yes."

"But when we came in just now, we heard the urge to relieve pressure

Chapter 113                                                             

"This is also something that I feel strange." Lai thought, "but things like air pressure can actually be faked through the form of a restart. I think someone must have been here before, but they don't want us to know, so they deliberately restored the scene to a certain extent before leaving."

Qu Xiao was puzzled by this: "What is the meaning of their doing this?"

"I don't know." Lai shook his head and turned his gaze back to the terminal. He suddenly frowned.

"What's wrong?" Qu Xiao asked.

Lai replied: "I seem to have found some unusual traces..."

"What trace?" Looking at Lai's sudden change of expression, Qu Xiao suddenly became nervous, "Is it a trace of being visited?"

"That's right..." Lai looked at it a few more times and finally confirmed that he was not wrong. "I retrieved a string of codes in the background that did not belong to the original operation code of this machine. Logically speaking, after repeated inspections by the company, such obvious bugs would definitely be eliminated, but......the string of codes was kept intact. This would definitely not happen if it were placed at that time."

"So, is this left behind by later outsiders invading the system?"

"I can't confirm it yet, but I should be able to think about it from this aspect." Lai did not directly deny Qu Xiao's guess, "But I still feel very strange, because in a sense, the intruders who can hack into it should not make such low-level mistakes... It's really incredible that such obvious traces have not been cleaned up."

"Is there a possibility that this is the code that already exists in the system?"

Although Qu Xiao does not understand the knowledge of code writing, his guess is still very reasonable. Lai immediately adjusted his thinking and re-checked it. Then he found that Qu Xiao's speech "a blind cat hits a dead mouse" really has hidden logic!

"You know this, too?"

He subconsciously thought that Qu Xiao also had relevant knowledge as a foundation, but Lai still felt very strange in his heart. In his opinion, artificial humans with the identity of guards should not have the ability to involve the field of code writing in any case.

"Haha, I don't understand." Qu Xiao smiled awkwardly, "I just think you said that, and the other party would definitely not be so stupid... So I guess if this thing was originally in this system. Judging from your current appearance, I guessed it right?"

"Yes." Lai nodded with a serious expression, "I just tried to run the simulation once, and the program... there was no error."

"So that's what this string of code itself is from this system?"

"Yes." Lai nodded, "But I can guarantee that it is definitely not within the scope of the original code."

"Uh, can you say it a little more plainly?"

"It means that this thing should have been hidden at the beginning, but for some reason, it was activated artificially and mixed into the operation of the program in the middle."

“So what impact does it have?”

“I’m still watching…

After about a minute or two, Lai's movements gradually slowed down.

"How is it?" Qu Xiao asked uneasy. From Lai's expression, he could already see that things might have exceeded the latter's previous estimate. "What has this code changed?"

“The operation mode of this device.”

"Ah?!" Qu Xiao didn't react for a moment, "What?!"

"The overall operation mode of this device has been changed by the addition of this string of codes." Lai said in a deep voice. "I just simulated it again. This change is very subtle from a small perspective, because it does not change the effect of the details, but... the overall transmission and reception mode of the external signal of this device."

"To put it more simply, the effectiveness of this device has been activated into another form. Didn't I say I wanted to use it to find someone? Now, I'm afraid it won't work."

"You mean, the function of this device has been completely changed?!"

"It can be understood this way."

"Just because of a string of code?!"

"Don't underestimate this string of code." Lai sighed, "Although it is very different from the original code in terms of structure and can be easily found at a glance, in terms of performance, this string of code is far more difficult than the original code. People who can write such a code with "reverse writing efficiency" are definitely powerful even in this era, at least... I can't."

"What does the reverse writing performance... mean?"

"You can understand that it recodes all the original codes' operating rules." Lai raised his hand and rubbed his forehead. "Now the function of this device is no longer signal monitoring, but signal transmission. I was actually quite surprised why the company designed such a cone-shaped building. Now... I understand."

"You mean, from the very beginning, Gaota Company has already made plans to treat the entire building as a base station that sends signals?"

"I'm afraid it's like this." Lai nodded, "Although this device is underground, its veins have already extended along the elevator shaft to the top floor of the building, a height of several hundred meters. Combined with the load capacity of the device itself, this is simply a huge signal transmitter!"

"Then why should the company do this?!"

"Why...hehe, why..."

Lai's expression at this time had turned dead.

"If you think about it a little, you can guess it..."

"I... just couldn't believe it."

Qu Xiao wanted to speak but stopped.

"If this signal is transmitted to space..."

"For human civilization, it is like being illuminated from the night with a flare."

Lai responded.

"As far as I know, since the establishment of the former World Republic Federation, the Tower Company has set up such a building in almost every large city. If the installations under these buildings have been uniformly modified to operate, the spread of this signal will lead to the complete exposure of the planet we live in to the monitoring of foreign civilizations!"
