32 days

Layer upon layer, at least 100 meters of concrete is buried above the living space of Yi Alan, which makes one feel suffocated when one thinks about it.

Yi Alan walked desperately to the refuge room on the fifth basement floor. Zhou Yan'an was right, at least he didn't lose his life because of it.

Suddenly, he heard a sound, click, click, faint but regular sound of electronic equipment.Under the ground buried in thick soil, it looks very strange.

Yi Alan stood still, turned her ears to listen carefully, and then followed the sound, looking for it lightly.

He confirmed that the voice came from this office, and the door plate said "Military Equipment Data Recording Room", which should be responsible for recording and screening the purchase and consumption of weapons.Pushing open the door, no surprise, there is no one inside, there are four desks in the field of vision behind the door, several computers and piles of folders are placed on the desks.The weird sound came from the printer on the other side of the room. It was still working, and a piece of A4 paper was spit out.

Then, the printer went into working mode again, humming and printing.

Yi Alan took a step back. This scene inexplicably reminded him of horror movies, such as the classic segment of repeatedly tapping the typewriter in "The Shining".

Standing quietly for a few seconds, Yi Alan finally couldn't help the curiosity in his heart, walked over, still thinking in his heart, he is now like the bewitched person in the horror movie, going to sign the contract uncontrollably Under the devil's contract.

There were three lines of characters written on the paper, and the format looked like a letter from a distance.

Yi Alan didn't touch the paper, but leaned forward and took a few glances from the air.

His pale face, which was similar to white paper, seemed to have been splashed with lively colored ink in an instant, and surprise, shock, and surprise emerged one after another.

I saw that it was written in correct Song style on the paper:

"Little A:

I am aware of your plight, and if you want to leave, I will help you, but you have to take risks, and your life may even be in danger, but you are actually safe now.

If you don't want to, you don't need to read the following content, just go to the refuge room.

Joker”

Surprised and surprised, Yi Alan blurted out "Joker" in disbelief, although Joker will not answer him now.What makes Yi Alan happy is that he has not completely lost contact with the outside world, which gives him great comfort.

After being shocked, Yi Alan suddenly realized after a little thought.

No need to wonder how the Joker knew he was trapped underground, the uncrowned king of this world would not be able to hide such a big event as a missile launch. Joker must have traced the missile all the way to here through his hacking method, and found that the person attacked was actually Yi Alan.

The damage to the signal adapter and the accumulation of concrete all affected the transmission of satellite radio signals, so Yi Alan and Zhou Yanan lost contact.But the currently affected radios are actually radio waves in the VHF and UHF frequency bands that carry a large amount of information.However, VLF and ULF, which carry little information, can still pass through thick concrete with difficulty.Because of its better penetration, very low frequency and ultra-low frequency communication technologies were mostly used in deep-sea submarines before, but limited by the small amount of transmitted information, they are usually only used for emergency contact. Submarines in deep seas receive ultra-low frequency radio transmissions. Incoming emergency instructions, it will float to the surface of the sea to receive high-frequency signals with more specific instructions.

Apparently Joker is using very low frequency and ultra low frequency communication at this time, sending out information compiled in Morse code or other relatively simple information forms, and then translating on the ground to print out what he wants to say from the printer.

Then why did Joker save himself?Yi Alan has always felt that Joker is neutral, but at the same time a bit paranoid and innocent.It would be better for him to observe these events indifferently than to interfere with them.

As if knowing what Yi Alan was thinking, the next piece of paper spit out by the printer answered his question.

This time, Yi Alan reached out and took the paper and read it carefully:

"You are the first and only resident of my Internet world. Maybe you have an extraordinary symbolic meaning to me. If you are trapped here, you will never be able to live in my Internet world , I don’t want to see this kind of thing happen, so after hesitating, I decided to rescue you. I want to tell you my method, without my explaining, you can see the danger, and you can make a decision after weighing it.”

The solution is still in the third sheet being printed.

The waiting time was extremely long, and Yi Alan couldn't wait to pull it out to see before it was completely spit out.

Bold and crazy ideas.This was Yi Alan's first reaction after reading it.

If you fail, you will really die.It was an inevitable second thought.

Yi Alan pinched the paper, and the lines of words that were printed so clearly gradually turned into a whirlpool of madness in his eyes, and he was caught in a tug.

A fourth sheet was also printed.

"If you wish, this is the preparation you need to do next: first put on a set of the thickest and highest-spec explosion-proof suit, in the fifth military equipment depot on the left side of the corridor on the fourth floor underground. Then put on the full-body mechanical exoskeleton , I know you know how to use an exoskeleton. The photo of you representing your school in the exoskeleton research and development team during your postgraduate period is still hanging in a corner of your school’s official website. Maybe there are differences in how you use it, but you should understand after a while...

If you don't want to, I can't get your answer, so I can only proceed rigidly according to the original plan, so you only have three or ten minutes now, either follow my instructions, or go to the refuge room to hide. "

Seeing the last line of words, Yi Alan was shocked, and there was not much time left for him to think.He has to make his own decisions and no one can help him.

He just had to ask himself one question.

Is there anything out there that cannot be given up anyway?Is it important enough to be brave enough to bet your life?

Yi Alan thought of Zhou Yan'an.

Zhou Yan'an was on the way flying over. Thinking of this scene, Yi Alan felt sour emotions in his heart again. After his eyes turned red, he immediately turned his head and ran out of the office. Instead of going to the refuge room on the fifth floor, he climbed up to the fourth floor. Floor, find the explosion-proof suit and military mechanical exoskeleton.

He didn't want Zhou Yan'an to fly here, so he could only hover lonely, and there was always 100 meters of concrete between them.

The explosion-proof suit weighed one hundred catties, and Yi Alan, who had no relevant training, was so crushed that she could hardly walk when she put it on.Fortunately, the exoskeleton warehouse is in the next room. Yi Alan, who was dressed like a black bear, struggled to move over there, and swiped the commander card he got at the beginning to enter the warehouse.

The atmosphere of the horror movie is more intense. When you first enter the exoskeleton warehouse, it is like entering a hell full of skeletons.

A mechanical exoskeleton is a power mechanical structure composed of metals. The more common ones include various prosthetics. Military exoskeletons are more prominent in performance and have a wider range of uses. They are often used for special operations in complex and dangerous environments.

The whole-body mechanical exoskeleton can fit the human body in multiple directions, strengthen the strength of the limbs, and have a protective effect.Although it seems that this kind of exoskeleton stands there like a bare skeleton, if the research can continue, it will develop the prototype of the mecha in science fiction works.

Yi Alan found a full-body exoskeleton with a relatively large size, and put it on awkwardly.Now he already has the dual protection of explosion-proof suit and exoskeleton.

Of course, Joker wants him to wear an exoskeleton, not just for protection.

According to the exoskeleton experience in memory, Yi Alan can barely use it after a little exploration.Because the extension of the exoskeleton in the past has greatly increased his body strength, so that his body seems to be supported by something now, so he doesn't feel that the explosion-proof suit is particularly heavy.The exoskeleton on the sides of the legs and the soles of the feet can provide forward momentum, allowing him to walk like flying even with a heavy load on his back.

Although you suddenly get the help of external forces, you may not be able to adapt.At the beginning, Yi Alan couldn't hold back her speed and didn't have time to turn, so she bumped into the wall and fell to the ground.

Well, it doesn't hurt at all.Yi Alan in the shell cheered himself up, and the exoskeleton on his arms supported him lightly on the floor, which gave him enough strength to make him stand up easily.

Yi Alan plucked up his courage and walked towards the place Joker told him.

On the way, Yi Alan heard a familiar voice again. When he passed an open door, he saw a printer working inside.Yi Alan walked in, raised his heavy hand, the extremely hard metal claws of the exoskeleton, gently picked up the piece of paper with the strength of sniffing the rose.

"You need not be afraid of the terror of the night, nor of the arrows of the day; nor of the plague that spreads in the dark, nor of the poison that ravages at noon. Though a thousand men fall by your side, and ten thousand men fall by your right hand , but no disaster will come near you."

Yi Alan is still going up, all the way to the third floor underground.

The ceilings of the three basement floors fell down, the power was cut off, and the building was pitch black and chaotic. Fortunately, the basic framework was still maintained and did not completely collapse.

The helmet lights up, and by manipulating the hard exoskeleton claws in his hands, Yi Alan can smash and remove the ceiling, broken walls, office utensils, etc. in front of him without difficulty, and clean up a walkable path. Come on the trail.However, the current exoskeleton technology can only provide a certain amount of help, and it cannot prevent and kill gods.Yi Alan could only choose the best way to go, carefully walking through the messy floor.

Yi Alan looked at the time, more than 20 minutes had passed.He has to hurry up.

The position he came to was at the edge of the entire building.From the perspective of the all-knowing architectural plan drawings, the underground building is roughly hexagonal. At this time, Yi Alan is standing near one corner of the hexagon. The concrete about three meters thick is composed of soil and rocks. the crust.

Yi Alan quickly found a location in the area given by Joker. He hid under a huge and thick solid wood table, curled up slightly, covered his head with his hands, and closed his eyes to wait.

Wait for that crazy and daring escape plan.

And 10 minutes ago, a ground-penetrating missile equipped with a conventional warhead was launched from a missile silo in the territory of Huaguo, and its destination was the Zhonghe City Army Base, which was the place that had been devastated by two missiles.

Zhou Yanan's airborne radar detected the missile, and he only hoped that Yi Alan had already hid in the refuge room.

Hidden well, come on.

In the dark, Yi Alan recalled the method proposed by Joker, let him go to the top floor where he can go, and then protect himself at the edge. Joker will hack into a missile launch system and launch a ground-penetrating missile to land near the building. At that time, the ground-penetrating missile will penetrate the surface of the ground, and the shock wave generated by the explosion will lift off rocks, soil and walls, blasting a large open pit .

This requires extremely accurate data. The position and depth of the missile landing must be just right. It needs to have enough energy to break through the thick wall, but not too deep, otherwise the interior of the building will be messed up, so that As for the complete collapse, Yi Alan will be buried to death at that time.

And Yi Alan had to be right on the edge of the shock wave, he couldn't be injured by the shock wave, and he couldn't be too far away from the open pit that was about to be formed, otherwise he wouldn't be able to pass through the already crumbling and completely blocked by the third bombing. Three floors underground.After these many stringent conditions are met, he can rely on himself and the strength of the exoskeleton to break through the last layer of obstacles, enter the open pit, and leave the closed underground building.

One link went wrong, and he was either blown to death alive or crushed to death by a heavy object. The best result was buried in the ground and then suffocated to death.

The author has something to say:

"You need not be afraid of the terror of the night, nor of the arrows of the day; nor of the plague that spreads in the dark, nor of the poison that ravages at noon. Though a thousand men fall by your side, and ten thousand men fall by your right hand , but no disaster will come near you.” Quoted from the Old Testament Psalms.
