Steel steam and flame

Soon, the surrounding warm temperature began to drop sharply, and dry and cold air poured in from the end of the long tunnel. In the light of the searchlights arranged in a triangle, you can also see small snowflakes that have not been swallowed up by the beam.

The tunnel is very large, with two neatly arranged railways intersecting inside it. At regular intervals, you can also see an indicator light that is always on. The sound boomed here, constantly superimposed, oppressing the ears of everyone on the queue.

The warehouse is located in the middle of the Xuefeng Mountain. It will take about a few minutes for this long heavy train to drive out of the Xuefeng Mountain. We are still in the stage of gradually accelerating. The speed of rearrangement of fully loaded goods can only increase slowly, which is a time-consuming process. The strength of the connection structure between carriages is limited, and there is always a limit to breaking. Speeding up too quickly may cause it to disconnect.

The heavy train made a huge noise and moved forward slowly in the tunnel. Shanerna stayed in the control room by herself, sitting on a chair to rest. She placed the sniper rifle on the console, and the indicator light illuminated his body with red, blue, and green lights.

Shan Erna originally had golden pupils, and there was not much racial difference among the people on the mainland. Now she was looking at her sniper rifle in a daze under the bright lights in the control room, her hand stroking the dark gun body from time to time, thinking about something.

She was very tired, from all kinds of physical exertion, and now she wanted to take a good rest. But she still remembered that the enemy had not been eliminated, but she was not sure whether that person was on the rear line, and his position was completely undetectable. After a while, there was no longer any clue about the enemy.

"It's also possible that this train didn't get on the train at all." Shan Erna sighed. She touched her torn hair at this time, hoping that this would be the case. This result may be the best for herself and her enemies. The relationship between the two has become very fair, which may lead to an uncontrollable situation as a result of their battle. She just wants to leave here as soon as possible and return to her country.

She vaguely felt that the enemy might have seen through her detection method through some phenomena. As a basis for being an excellent sniper, this ability is an extremely important secret to Shan Erna herself. This does not mean that all the strength today is based on this point, but it is definitely an important part of this strength.

Not many people know the specific situation. When she underwent staged surgical transformation, she was already an excellent student. Some things are already clear in her heart, and she doesn't need others to remind her. It has always been well hidden. After all, according to the characteristics of the operator's body, the pair of dark green eyes that can be described as mutated have indeed become a unique and powerful weapon.

Now this ability may no longer have a specific effect on the enemy, which makes Shan Erna feel a little uneasy. There were only a few people left alive, and even the teachers and inspectors were all turned into corpses. She doesn't care about fighting now. Without absolute certainty, she is more inclined not to conflict with the enemy. If you are not careful, you will lose your life, and no one can bear the price.

After sitting in the control room for a while and feeling her body re-energized, Shanerna stood up and moved her body in the limited space, doing simple stretching movements. After the tunnel was re-listed, she had to gather those who were still alive in the re-listed tunnel.

Everything went black before my eyes. After the reset, the temperature on the surface of the red copper pipe increased by a few degrees. It was not a good experience to be caught in it now.

The huge steel wheels were rolling loudly in front of them. The huge collision and friction sounds already caused a slight pain in the ears.

Fortunately, the dry and cold wind howled from underneath the car, and Cassia felt a little better. He was holding a revolver at this time and was regularly tapping the red copper pipes around him with the handle of the gun. There was indeed a clear percussion sound, but under the huge noise of the rearrangement itself, this sound was completely absorbed by the noise before it could be dissipated.

But there is still a way to capture these percussion sounds, which are transmitted through the steel medium of the rearrangement. If you put your ears on the steel structures of the rearrangement and calm down, you may be able to capture it, but it is not certain.

He was sending code words to Major Barron who was hiding in the cargo compartment, hiding among cold, temperatureless steel objects. The major's own heat really worried Cassia. He himself did not understand the details of the enemy's method of detecting temperature. He didn't know to what extent the detection method could be refined, and whether it would always require eyes as an organ to activate it.

And there will definitely be a limit to this method. According to the colonel's original description of the battle in the forest, he and several captains stayed at the enemy's feet for a long time. But at that time, the enemy did not use this method to discover that the major and the others were hiding under their feet.

Then, by the time the sniper actually discovered the captains, it was already the moment when the captains had just emerged from the shell holes. So there must be a rough limit within it, perhaps the radius of the circle of about six hundred meters. And when the intervening medium layer is thick, this detection method will also lose its effect. As for the specific value of this limit, Cassia does not know now. The fragmented information was not enough for him to push it aside.

I have hit the code word with the butt of my gun several times. Every time Cassia repeated it, she increased the intensity of the tapping, making the sound louder and the speed also increased. The rearrangement was still in the dark tunnel, so it was the best time for the major to move his position. The enemies hiding in the cargo compartment will also come out at a certain time. According to the rearrangement, the actual departure time is not exactly 4 p.m. So Cassia speculated that the final result should be that the enemy side won. But Cassia did not fully understand how many people survived in the end and where they were on the train now. He has been hiding in the cracks of the red copper pipes, and it is not convenient for him to move around.

It had been cycled ten times, and the cycle was completed. Just when Cassia was about to start the eleventh time, he finally caught the same rhythmic sound with his ears pressed against the bottom of the car.

"Received, thank you." The loop continued until Cassia typed out a reply, and then it stopped.

In that code word, he briefly explained the conjecture that the enemy could detect the temperature, and told the major that it was best to hide secretly. It would not necessarily be beneficial to fight with the enemy now.

Soon after, the major also moved to the bottom of the car, holding the heating pipe. It was much more convenient for the two of them to talk through the connected pipe.

"You're so lucky. Without you, I might have died hiding in the cargo compartment without even knowing." This was the major's first sentence, although this emotion could not be reflected in the knocking sound transmitted inside the metal. a little.

"Temperature detection does have a huge advantage against us surgeons. I think this is the same as those second-class creatures. Because of the infection of dragons, they, like humans, are moving forward in their own evolution. One step. During the process of growing up, due to the influence of environmental factors, various strange abilities were developed to survive in the cruel natural environment." Major Barron typed a long series of code words in one breath. , "You have to know that our impact on the natural environment has tens of thousands of times more feedback information than ordinary people. Like those second-class creatures, our evolution speed has been accelerated a lot because of these."
