Chapter 118: "Four hundred and four-Not-Found"

　　 "Boom!"
　　 The can slammed on the airtight door, making a more dull sound, but other than that, nothing happened.
　　 "Is it thermal infrared sensor?"
With a sound, Qi Lin wiped a burning rod, and then threw it away. The red and white fire from the burning rod instantly illuminated this small area. Although the burning rod was a low-temperature flame, it was used to Triggering thermal infrared detection is also completely enough... However, Qi Lin's "predicted" mechanism was still not triggered.
　　 "……"
　　 Qi Lin was silent for two seconds, only then cautiously walked to the air-tight door and wiped off the loess covering the door with his hand.
　　 In addition to the mottled national emblem of the Republic, the airtight door is also painted with three corner-cut square font numbers-"404".
　　 Seeing these three numbers, Qi Lin could not help but blurt out: "404, Not-Found?"
　　 "404, Not-Found" This is a well-known HTTP status code on the Internet in the old age, and its meaning is that the address entered by the user cannot be indexed or does not exist when the user is browsing the web.
　　 And in the early years of China, there was also a city called "404". It was a city that could not be found on the map. When the city was established, it was to set up a base for research on nuclear weapons.
　　 Although the city has gradually ceased to be a secret, the "404 City" still cannot be found on ordinary maps, and any mail or express cannot be sent to this "non-existent" city.
　　 Then, whether it is the 404 error code on the Internet or the "non-existent" city, what does it have to do with the airtight door...this arsenal?
　　 Could it be said that this is an arsenal that "does not exist" and "cannot be found"?
　　 Qi Lin's heart became more and more confused, and the motion range of his hand increased again, and soon, all the loess stained on the airtight door was scraped off.
　　 After the entire circular airtight door appeared, Qi Lin found a very inconspicuous card slot in the lower right corner.
　　 Qi Lin put the gray card on the card slot and compared it, the size is exactly the same.
　　 "That should be here, yes..."
　　 aligning the gray card with the card slot, Qi Lin cautiously inserted the entire gray card in.
　　 "呲"
After the gray card was inserted into the card slot, Qi Lin clearly heard the sound of a gas jet coming from behind the metal airtight door. Then, the entire airtight door that had been sealed with dust for many years began to rotate slowly.
A lot of dust was shaken down instantly and filled the secret road. Qi Lin quickly covered his mouth and nose. The air-tight door turned a full three hundred and sixty degrees before it retracted back ten centimeters, rolling One side after entering the door.
Airtight doors like this are all large hydraulic systems. The thickness of the door panel alone is fifty centimeters thick, which is almost twice as thick as the actual refuge door. This kind of door cannot be violently used. To break, unless it is directly exploded with a micro nuclear bomb, or a laser cutter is used for ten days and a half...
The two-meter-diameter airtight door slowly opened. Qi Lin used his dark vision to the fullest and looked inside. However, inside was just a metal corridor for one person to pass through. It was about a hundred meters long. A corner made Qi Lin's eyes unable to peep deeper.
　　 "Is this really... an arsenal?"
　　 Qi Lin wondered, it was not that he had never seen a facility like the arsenal, but it was the first time he had seen it like this.
　　 put out the burning rod, Qi Lin climbed into this corridor.
　　 When his feet just touched the metal ground of the tunnel, a row of faint blue cold light lights up in the tunnel, and the air-tight door behind him suddenly slammed and overlapped.
　　 "Grass?!"
Qi Lin immediately ran to the airtight door, and saw that the gray card was spit out from another card slot behind the door, but when Qi Lin wanted to insert the card back in, the card slot seemed to be blocked. The same, I can't get it in.
　　 "One-way channel?"
　　 After many attempts to no avail, Qi Lin turned his head and looked at the corridor that had been rendered into a blue by the cold light, and a strange illusion could not help but rise in his heart.
This tunnel is full of a strong sci-fi style. When you are in it, you seem to have traveled through certain sci-fi movies. In Qi Lin’s impression, only those research institutions and other facilities like to create this tune. And China’s military has always liked the fortitude and iron-blooded style. If this is an arsenal, it should definitely not be like this!
Qi Lin first carefully inspected the metal walls on both sides of the tunnel, as well as the ceiling and the ground, and found that the tunnel seemed to be made of a single piece of metal, and there was no gap in the splicing at all. This also confirmed Qi Lin's Guess, if the military does, even if it is to reinforce the tunnel, there is no need to use such a flashy method.
　　 Moreover, the air inside this corridor is still very fresh after it has been closed for so long. In other words, there should be a ventilation duct connected to the outside in this "404 Arsenal".
　　 Qi Lin dipped his index finger with a circle of saliva, then stretched it into the air
"what?"
　　 As usual ~EbookFREE.me~ If there is fresh air, the direction of the influx should be the end of the tunnel, but after three minutes, there is almost no difference in the speed of water evaporation in all directions of the index finger.
Qi Lin then once again set his sights on the metal wall of the tunnel-in the old days, there was indeed a nano-metal material, which looked very flat and smooth, but in fact there were countless small holes that could not be seen by the naked eye. The gas molecules pass through-but the price of this material is very expensive. If this one hundred-meter-long corridor is all made of that material, plus the rear ventilation device...
　　 That is simply a sky-high price!
　　 "Here...what exactly is this place?"
　　 Obviously, if you want to know the answer, you can only go inside.
　　 With the faint blue light, Qi Lin held the gun and began to slowly move forward along the corridor, but every step forward, the uneasiness in his heart would deepen.
The rubber-soled army boots stepped on the smooth metal floor, and the sound made people can't help but feel a bit creepy. Qi Lin suddenly felt that this scene should not be a pure science fiction film, but a science fiction similar to Resident Evil and Alien. The thriller was out.
The zombies in Resident Evil can be seen everywhere in the wasteland now. As for the monster of the opposite sex, the strength of the E-level to D-level will be the only thing that is frightening. The sense of tension and unknown that people hang up every nerve.
If a few zombies suddenly rushed out from the end of the tunnel, croaking and gnawing on Qi Lin’s nose, the stone hanging in Qi Lin’s heart could be put down in half, even if he was a soldier of the opposite or a predator. But I just don’t know what is waiting for me at the end of the tunnel, this is the most terrible!
