North of the city, natural gas control station. Pen, fun, and www.biquge.info

Lin Xuan arrived at the natural gas control terminal after running for half an hour, but there are not many zombies here, probably because the surrounding residential areas are far away.

There were only a few scattered zombies in overalls tilting their heads and wandering aimlessly around the doorway, and nothing else.

Lin Xuan didn't even cut out the claw form, for the zombie who was limping and trotting immediately after seeing him, he gave a punch one by one after close and flew up and lay on the ground, the hit part as if it had been run over by a truck.

Very unimpressively spit on the still convulsive corpse, Lin Xuan strode into the gate of the natural gas control station, and the moment he pushed open the glass door, a cold wind that should not exist rushed towards him and hit him in the face, and the temperature was significantly lower than the outside world, making Lin Xuan shiver.

How can it be so cold here?

The temperature inside the control station is unusually low, although it is autumn, the temperature outside can still be roughly maintained at about 20 degrees, but the inside of the control station is only 12 degrees according to rough estimates, which is too strange to be the temperature that is too unreasonable.

Realizing that this was a bit unexpected, Lin Xuan, who felt that something was wrong, subconsciously frowned, slowed down his pace of progress, and carefully examined every detail on the road.

A rough diagram of the structure of the building hangs on the wall in the center of the hall, and the main control room for adjusting the pipes is not far away, but now there is no electricity supply in the whole city, and after four days, I don't know if the backup power stored inside to supply emergency power will still be available.

Call~

The obviously menacing air flow blew from the internal passage, Lin Xuan, who was in the hall, really felt the changes brought by the cold current, it is estimated that the low temperature of five degrees had broken through at that moment, although it was not so cold after the cold current disappeared, but this inexplicable cold current still made Lin Xuan curious.

Lin Xuan is just not very accustomed to the sudden drop in temperature, even if it is minus twenty degrees Celsius, his body can guarantee the activity, so he just wants to go to the natural gas control room now to see the situation, and the rest will be said later.

Curiosity doesn't just kill cats, so don't always try to figure it out.

Came to the general control room, the temperature here was about the same as the hall, unscrewed the door handle, and found that the door was locked from the inside, Lin Xuan violently kicked open the door of the general control room, and the iron door that broke away from the door frame under the violence just pressed the two zombies inside under the door.

Fiercely stepped on the door a few times, and there were bursts of crisp clicks under the door one after another, and then the fierce resistance below completely disappeared, and the two zombies that were suppressed turned into mud.

Ignoring the black blood flowing wantonly on the floor, Lin Xuan walked to the panel of the main control room, fortunately, the backup power supply was still running, that is, the main control room could still be used.

After looking for a long time on the pipeline deployment map as complex as an ant's nest, Lin Xuan, whose eyes were sore, finally found the pipeline under the mother nest, and roughly estimated the pipeline flow, which should be no problem.

Well? Lin Xuan was just about to adjust the switch of the pipeline, the red icon flashed on the screen of the main control room, it seemed that a valve was blocked by something, if you want the gas accumulation to explode and blow up the mother nest located on the surface, you must open the valve to make the input pipeline unblocked.

However, the blocked pipeline did not explode? After repeatedly checking the situation of the surrounding pipelines, it was confirmed that there was no safety incident, which made Lin Xuan puzzled, could it be that something was stealing gas?

Thinking of the strange low temperature in the control station, Lin Xuan couldn't help but retreat a little, what type of infected body is this time?

After setting the status of the other pipelines, Lin Xuan left the general control room and went to the underground passage, from where he could go to the underground pipe, and he wanted to see what was going on with that pipeline.

Even if there was a new infection with a strange form, its DNA might be able to unlock useful new abilities for Lin Xuan, and for Lin Xuan, every opportunity to become stronger could not be missed.

Passing through several halls, Lin Xuan also used violent means to open the door of the underground passage, and the cold air that faintly emerged from it proved to Lin Xuan that the location here was abnormal, and this low temperature was mostly related to something underground.

The underground passage is probably enough for three people to walk side by side, but it is still narrow, and for some reason, the lights on the walls do not respond, is it that there is no power?

Relying on the detection of virus sonar, Lin Xuan walked steadily in the underground passage with almost no light, the environment here was surprisingly quiet, nothing could be seen, nothing could be heard, and it was as panicked as a century-old grave.

The only thing that walked with Lin Xuan was the sound of his breathing and footsteps, and the two faint voices that were usually unnoticeable were now the only things that could prove that Lin Xuan was still in the real world.

Ka~Ka~

There seemed to be a sound echoing in the underground passage, because there were no other sounds mixed in, Lin Xuan could hear it very clearly, but because the sound was not very loud, and there were endless echoes in this underground passage, he couldn't hear what the sound was.

Get closer to find out.

Sensing that the unknown object that might be blocking the pipe was ahead, Lin Xuan became nervous and continued to follow the feedback image of the virus sonar, but the speed of progress slowed down, and he was more careful when moving.

Airplanes~

The strange sound of the horn spread through the underground passages without warning, low and thick, without any emotional fragments, only simple sounds.

But Lin Xuan felt that it was more like the howl of some kind of creature, with no other basis, it was purely an inner intuition.

zi~la~

Not long after the trumpet subsided, another voice sounded not to be outdone, with a strong sense of provocation, as if to challenge it.

What the hell is it? There seems to be more than one.

Lin Xuan stopped, pricked up his ears and listened to the movement in front of him: it seemed that there was a dispute between the two, the passage in front was no longer calm, a smiling but conspicuous point of light appeared in Lin Xuan's sight, and the dense explosion sounded like fireworks for the New Year.

z~i~la！

One of them seemed to have suffered a loss, in Lin Xuan's sight, the azure light bloomed violently, and at the same time, there was a cool air flow along the passage, and the sound of fighting was getting farther and farther away, but there was no intention of stopping.

Lin Xuan waited in place for another ten minutes, the sound of the fierce fight had long since passed, and only a little of the luster of the flames could be seen at a glance in the endless darkness, which was very dazzling.

It was speculated that the two unknown creatures had indeed gone far away, and after opening the virus sonar again and searching in detail, Lin Xuan was relieved to check the scene left behind during their fight.

Scorching flames and biting ice crystals appeared in one place at the same time. The walls of the passage seemed to have been dug open by unknown creatures, forming a space the size of a football field, where some unextinguished flames were still burning, along with large chunks of ice fixed irregularly to the wall, braving the cold.
