Seemingly...... The person who tore up those two pages of the file probably didn't want the experimental data to fall into the hands of the mastermind.

However, this does not mean that it is foolproof...... As a member of the original experiment, even if he didn't have those data, Xia could rely on his memory to copy the previous experimental process...... What's more, Qin, the most critical element in the entire experiment, is now under their control.

Qi Lin rolled up this top-secret file and stuffed it into his personal pocket, he really wanted to read this experiment report carefully, but time did not allow it...... Once the bodies of those two officers and Scott are discovered, the entire Fort Yukon base will enter a state of high martial law, and at that time, if Qi Lin wants to enter the underground laboratory again, the difficulty will probably not be at the same level as now.

It's hard to sneak in now, though......

After rummaging through the files in these large wooden boxes, Qi Lin finally found the design of the underground shelter that had been eaten by insects in the corner of the box, and now, it was already eleven o'clock in the middle of the night.

If the time limit was calculated according to four o'clock in the morning, Qi Lin would have five hours at most.

The nuclear vault beneath the Fort Yukon base is a standard large vault with a total of sixteen floors, the deepest one is located 185 meters underground, and has a total area of more than 1,000 square kilometers, more than five times the size of Washington, D.C., the political center of the country.

Although this large shelter was originally intended to accommodate the troops stationed in Alaska, it was not the official of the United States that built this large shelter, but the PROM Foundation, and it was for this reason that laid the groundwork for various changes in the future.

Although Qi Lin didn't know how the soldiers in the shelter were driven to the surface by the mastermind and became a "human radiation purifier", during the period when the Fort Yukon Vault was completed, the relationship between the Foundation and the mastermind was still in the "honeymoon period...... At that time, the mastermind had just been successfully developed, and the Foundation did not foresee the consequences of the awakening of the self-consciousness of advanced artificial intelligence, at that time, almost everyone in the Foundation was immersed in the joy of the completion of the mastermind, and the survival of human beings under the wasteland was guaranteed.

This statement is not wrong, indeed, if there were no masterminds, many of the world's many shelters would not be functioning properly, and the number of people who would survive would be very small......

And in this Fort Yukon Vault, there is a "replica" of the mastermind.

The data that the main brain needs to process at any moment is very large, and if you rely on the main brain itself, no matter how powerful its computing power is, it will not be able to process and respond to every request in every detail. This is like playing an online game, where the server will only pass packets to the client, and most of the computation will be done locally on the client.

However, the control system of the shelter is different, relying on the local computer alone, it cannot be synchronized and coordinated with the entire shelter network, and the cost of information transmission is ...... For a combination of these reasons, a compromise has come to mind.

That is, all over the world, several "replicas" of the main brain are built, and most of the data with low importance and priority are processed by these replicas, and the main brain ontology only needs to authorize and review the replicas, and a large amount of occupied computing power is liberated.

If this sounds difficult to understand, it is also a metaphor for online games, these "replicas" of the mastermind are like "server rooms" built in different regions, and the specific performance in the game becomes the partition of various regions, such as "Shanghai District 1", "Hong Kong District 2" and the like, or the name of the communication service provider to partition: "Telecom Zone 1", "Netcom Zone 1......

The same is true of the clones of the main brain, each of which is responsible for controlling an area, such as the one in the depths of the Greenland Ice Sea, which is responsible for controlling the region of Western Europe; Leshan's clones are responsible for controlling the Huaxia region and most of Southeast Asia...... The replica located beneath Fort Yukon has control over all of Alaska, half of Siberia, and almost all of Canada.

The mastermind has absolute control over these clones, and at critical moments, it can even turn any one of them into a new entity through data transfer.

In the underground shelter of Fort Yukon, the replica of this main brain alone occupies a total of four floors from minus 11 to minus 14 floors, as for the bottom minus 15 and minus 16 floors, one is an isolation layer filled with a large amount of thermal insulation materials, and the first floor is a fully automated large-scale geothermal energy conversion station, which provides a steady stream of energy for the shelter by collecting geothermal heat from deep underground.

As for the underground laboratory, it is located on the negative fourth floor, occupying an entire floor of space.

As for the negative 1, 2 and negative 3 floors above the laboratory, they are the military camp, the residential living area and the material warehouse, respectively.

There are more than thirty entrances to the underground shelter, half of which are located outside the Fort Yukon base, and these entrances must have been sealed by the mastermind, and the remaining entrances to the Fort Yukon base, it is estimated that only four entrances in the inner city are in active state.

"Inner City...... Hiss...... It's much more heavily defended than this outer city......"

The place where the scavenging bird fell was located in the inner city, Qi Lin also slipped out of the inner city, the garrison force and patrol density in the inner city are definitely not comparable to the outer city, and the soldiers stationed in the inner city do not even have night entertainment time, except for eating, sleeping and going to the toilet, all the others are on duty.

Moreover, the officers of the inner city army were also much more difficult to deal with than the officers of the outer city army, and the officer who dealt with the falling scavenger during the day was almost discovered by him.

Compared to the design of the underground shelter that Qi Lin had been looking for for a long time, the map of the Fort Yukon base was much easier to find, and this thing was hung in the most conspicuous place on the wall...... It's just that what makes Qi Lin a little speechless is that on such a map, only the regional structure of the outer city of the Fort Yukon base is marked, and the inner city part is completely blank......

Qi Lin thought of a possibility, the map of the inner city area could only be found in the inner city. The map on the wall is for troops who only have the right to be stationed in the outer city.

Qi Lin took the map off the wall and stuffed it into his pocket, then dragged the two corpses of the guards outside into the archive room, stuffed them into the corners, and blocked the two large wooden boxes in front of the corpses.

This is not the end, behind the big wooden box, Qi Lin arranged a small trap again, if someone pushes away or moves the two large wooden boxes, the taut tripwire will directly pull off the pull rings of the two high-power defense grenades, and the detonation time of these two grenades is set to 0.5 seconds, and the trigger only has a very short time to react after being triggered.

In addition to these two grenades, Qi Lin also left behind an incendiary bomb filled with napalm, which, after the grenade trap is triggered, will completely reduce the entire archive to ashes, erasing all clues.

After doing all this, Qi Lin left the archives and felt in the direction of the inner city.

Because of his experience in finding out of the inner city, it wasn't too difficult for Qi Lin to touch it again, but after he climbed over the wall that separated the inner and outer city, he fell into a somewhat awkward situation and he got lost.

Luck also accounted for a large part of the fact that he was able to get out of the inner city before, but now, in the face of the many forks and alleys in the inner city, Qi Lin didn't know which direction to go from, and where the four entrances to the underground were.

The location of the exit marked on the Vault design did not help Qi Lin in the slightest, as Qi Lin could not find a reference that could be used for comparison, and when the design was drawn, the fort of Yukon did not even have a foundation...... The situation on the ground is very different now than it was a few years ago, and the only thing that can still be used as an accurate reference ...... There is only latitude and longitude data for the entrance location.

However, Qi Lin's GPS equipment was destroyed when he escaped from the undersea prison, and the idea of relying on longitude and latitude data to find the entrance had to be stopped.

After much thought...... In the end, Qi Lin could only take a very time-wasting, but safest and safest way to explore at the moment, find a hidden place to hide, wait until a patrol soldier passed by, attach an idea beacon to the opponent's body, use the opponent's eyes to explore the surrounding area clearly, and at the same time find out the patrol pattern of the guards.

There will definitely be more guards at the entrance, and patrols will be more intensive, and with this clue, Qi Lin will be able to find the location of the entrance.

And it would be nice to be able to get some extra information through talking to the guards.

It's just that the Mind Beacon has a maximum distance limit, according to the upper limit of Qi Lin's ability, the farthest range of action is about five hundred meters, that is to say, a Mind Beacon can only help him explore an area with a radius of five hundred meters at most, and before entering the next unknown area, he must repeat the previous set of procedures.

Of course, 500 meters is still idealized data, in fact, the distance of the guards patrolling back and forth can be up to 200 meters before it is killed, and Qi Lin can only use 200 meters as a unit and slowly advance......

The process was undoubtedly extremely painful, but he had to do it.

There was no answer, no backup, no intelligence, everything was on his own.

There is a replica of the main brain here, with tens of thousands of troops stationed, and there are definitely not many hidden high-level evolutionaries among them, and this place is not an exaggeration to describe it as Longtan Tiger's Den.

In the eyes of anyone who has studied some military theory a little, Qi Lin's actions are no different from suicide.

……

The attachment target of the Mind Beacon has been changed to three, and Qi Lin has only advanced less than four hundred meters The fact is even more cruel than imagined, yes, a soldier's patrol distance is almost two hundred meters, but these two hundred meters are not necessarily a straight line distance, Qi Lin can detect the range through a single soldier is very limited, and it is only three hours away from four o'clock in the morning.

And Qi Lin's hope of obtaining information through conversations between soldiers has also been shattered, and these soldiers in the inner city will not engage in small talk at all during the patrol process, and will only have the slightest necessary communication after the handover......

From this little bit of communication, the only thing Qi Lin could know was that their changing of the guard was every six hours.

But this little thing is meaningless to Qi Lin now, let alone six hours, and by four o'clock in the morning, Scott's teammates or superiors find out that he did not return to the barracks on time, then it will be too late.

"Hurry up...... Walk faster and turn left...... Left...... Turn left and don't turn around! Qi Lin felt as if he was on patrol through the shared vision of the person attached to the telepath, but the body was not controlled by his will, and although he could see what the other person saw, could hear what the other person heard, and even the feeling of the cold wind blowing on his face, he was always just a spectator, a bystander who could do nothing......

At this moment, Qi Lin suddenly felt that a confinement in his mind seemed to be broken by his mind, and a crisp sound of shattering echoed in his mind, and at the same time, an invisible spiritual passivity emanated from him, heading straight for the soldier who was attached to the mind beacon.

The patrol had already reached the edge of their area of responsibility and was about to turn back, but one of the soldiers looked suddenly stunned and whispered to his teammates: "Suddenly I have a stomachache and want to go to the bathroom." ”

"Stomach ache?" His teammates turned their heads and looked at him with some puzzlement, "We're on duty now, why didn't you handle this kind of thing when you took a turn off just now?" ”

"I went to the toilet when I was on a break, but now it suddenly hurts so badly...... I don't know why, maybe it's a bad stomach, right? ”

"Got a bad stomach? We all eat the same food at night, why are we okay? Another soldier stared at him a little strangely.

"I don't know...... It's true...... I can't hold it anymore, if I don't go, I'm afraid I'll be pulled in the crotch of my pants......" The soldier bent down slightly, his hands tightly covering his lower abdomen, and his face turned red.

"Okay,, lazy people have a lot of and pee, go and get back, I don't want to patrol with a guy with poop in his crotch!"

"You move quickly, we'll watch it for you...... Of course, if the officer finds out, you can ask for a blessing! ”

"Thank you, brother!" The soldier waved his hand, clutched his stomach and ran out, turning left into a fork in the road.

And Qi Lin, who was hiding in the shadows, was completely sluggish...... To be honest, he didn't do anything, he didn't even use his mental power to order the soldier to turn left (of course, Qi Lin didn't have this ability either), but the other party just had a stomachache at this time, and it happened that the nearest toilet was next to that fork in the road.

Is this a cause of luck? …… No, no, Qi Lin obviously felt that he seemed to send out an invisible spiritual fluctuation towards the other party, and this sudden "stomach ache" must also have something to do with him.

The soldier had just run to the door of the toilet, but at this moment, he suddenly felt that his stomach did not hurt, and there was a situation similar to a "fragment" in his head, he couldn't remember what he was thinking in his head a minute ago, but he looked around a little dazedly, and began to walk back with a full stomach of doubts, and as he walked, he muttered in his mouth: "Strange, how did I come here......?" ”
