Chapter 520: Heat pipe

After the assembly of more than one hundred soldiers from the internal guards, under the leadership of the officers, they ran towards the main evacuation road of the industrial zone. If Qi Lin was right, these people should be helping to maintain order. The rumor that Vault 909 may be bombed is now spreading wildly among the residents of the refuge. Although no serious conflict has occurred, the small-scale riots have never been interrupted.
　　In the industrial zone, it's okay. After all, there are a lot of soldiers with guns and live ammunition staring at them, but no one knows how long this short-term stable condition can last.
　　 The power of fear is very terrifying. At this time, if a few guys who take the lead in making troubles jump out, the situation is likely to become out of control.
　　 Seeing that the people in the Xuanwu shell are also aware of this problem, then more than one hundred internal guards will be sent out.
　　 But for Qi Lin, this is actually good news. The guard power in the Xuanwu shell is reduced by one-fifth, the density of guards will definitely drop a lot, and the difficulty of sneaking in becomes even lower.
　　 Qi Lin put away the lenses, ran up the stairs full of waste to the first floor, pushed a forklift behind the door, and ran out of the factory.
The whole body of the basalt shell is made of opaque metal. Except for a few entrances and exits, there is no window. People inside can only rely on the surveillance cameras installed outside the basalt shell to see the outside scene.
　　 But in such a complex situation in the industrial zone, there will always be blind spots for surveillance cameras. Qi Lin uses these blind spots to quickly approach the basalt shell from the blind spots of the camera.
There are a total of four entrances and exits for the basalt shell. Two of the smaller entrances and exits are for people to enter and exit, and the other two larger ones are connected to railcar tracks to transport the fuel needed by the reactor and the waste generated.
Whether it is a small entrance or a large entrance, there are a large number of internal guard soldiers guarding it, and the large-caliber heavy machine gun is directly mounted inside the entrance. If an unidentified person wants to forcibly break in, it will take seconds. It would be torn into pieces by a 50-caliber Browning machine gun shell.
As for the trains of railcars used to transport fuel and waste, their energy has long been cut off. Let alone use them to rush into the basalt shell, even if Qi Lin pushes with all his strength, these are locked on the track. The train will not move at all.
　　 But if you want to enter the Xuanwu shell, there is not only one way to enter through these four entrances and exits.
　　 "heat pipe".
　　According to legend, Xuanwu is composed of a giant tortoise and a giant python wrapped around the giant tortoise, and this giant heat dissipation pipe with a diameter of more than four meters is next to the giant python wrapped around the Xuanwu shell.
In order to allow the pipeline to be quickly cooled without overheating, the heat dissipation pipeline is actually divided into four independent channels by a thick cross-shaped partition. Through the adjustment of the valve, the coolant that is vaporized is changed every time. It will only pass through two of the channels and switch every three minutes.
　　 The extremely high temperature of superheated steam can peel off the skin of the human body in just one second, and no one can go forward with the rush of steam, not even Qi Lin who is a Level 5 evolutionary in the game.
　　 The energy-gathering vortex may be able to absorb the energy contained in the steam, but the absorption speed is definitely not as fast as the steam cooks Qi Lin.
　　 But there are two other channels with no steam passing through the insulating partitions. Although the temperature must reach over 100 degrees Celsius, it is already in the tolerable range.
Qi Lin bypassed the four heavily guarded entrances and exits, and climbed along the metal frame outside the basalt shell to the side of a section of heat dissipation pipe. On that section of the pipe, there was a small door for technicians to use for maintenance. door.
The access door is controlled by a hydraulic valve. Fortunately, the design of the Xuanwu shell did not consider the
dead way
of intruders choosing the heat dissipation pipe. Therefore, the hydraulic valve of the access door did not use high-end electronic locks. It is an old-fashioned mechanical lock.
Qi Lin took out a thin iron wire, inserted it into the keyhole, and turned it slightly. Within two minutes, accompanied by a soft "click", a sound of gear rotation came from behind the hydraulic valve. The valve handle turned counterclockwise once, and Qi Lin only needed to turn two more times and pull it out to open the maintenance door.
　　 However, Qi Lin was not in a hurry to open the door—the door was faintly heard with a muffled noise, which was the sound of superheated steam passing through the pipe at high speed.
　　 If Qi Lin opens this inspection door now, it is most likely to be instantly killed by the direct steam.
　　 He waited for more than thirty seconds, the rumbling sound suddenly changed a position, that is, the high temperature steam switched the heat dissipation channel under the adjustment of the main valve, and the next switch was three minutes later.
　　 Qi Lin immediately opened the inspection door, and a scorching heat wave hit his face immediately. This feeling could not help but remind him of the scene when he was driving a simple power armor in the sea of ​​fire when he was at base 404.
The temperature of the inner wall of the pipe is terribly high, let alone knocking an egg, even if you throw a piece of pork belly on it, it can turn into a sizzling barbecue in minutes. Fortunately, Qi Lin is wearing a pair of special combat boots this time, although the appearance is just camouflaged. It’s the same as a pair of tattered goods picked up from the garbage dump, but just for the sole of the boot, Qi Lin spent more than a thousand resource points~EbookFREE.me~The temperature of the inner wall of the pipe may be used for baking iron It is grilled, but it can't melt the soles of these boots.
　　 Qi Lin plunged into the pipe and started to run quickly. He had to enter the inside of the basalt shell within three minutes. In addition, he had to find another access door inside the basalt shell.
　　 The soles of the boots are constantly tapping on the inner wall of the metal pipe, giving out a buzzing sound. Fortunately, thanks to the excellent heat insulation performance of the pipe, the sound insulation effect is quite good.
　　Especially when there is steam rumbling through the passage next door like a train.
Since it is close to the surface of the basalt shell, the heat dissipation pipe presents an arc-shaped curvature. According to what Qi Lin saw outside, he only needs to run down the pipe for less than two hundred meters to enter. To the inside of the basalt shell.
　　 Two hundred meters, it is only a matter of ten seconds.
　　 Due to the special design and structure, the temperature in the channel is dropping rapidly. Although it is still fifty or sixty degrees, a drop of water still begins to condense on the inner wall of the channel and drips onto Qi Lin from time to time.
　　 He has run more than 500 meters. It stands to reason that he should be in the tenth position of the Xuanwu shell. However, up to the present position, Qi Lin has not been able to find a second inspection port...
　　
　　 First set a small goal, such as 1 second to remember: 　shukeju mobile version reading URL:
