Once the correct solution is found and the metal cutting project is carried out efficiently.

With the roar of the light diesel engine, the output torque is reduced through a gear transmission and then fed to the cutter's alloy steel flywheel. Mars splashed with "squeaking" sound, and the burnt smell of metal friction spread in the air.

As soon as I got my hand, I felt that the metal outer wall of the "black wall" was not hard, and it was indeed easier to cut. Long Yun carefully cut for a while and stopped to observe. He soon found that the wall panel on the outside of the "black wall" was not too thick, and it was about three or four centimeters deep. The sawing felt like a saw through empty space. The first trace of the saw was made, and stopped to rest for a while before continuing to work. When the four traces were almost connected to each other, Long Yun put down the cutter and turned to using a hand saw and a crowbar to do this.

After all, the large piece of metal plate that was about to be sawed always weighed hundreds of kilograms, so he didn't want to be rashly knocked down by this thing and hit him on his body.

After resting and resting, he tried to pull the crowbar. With a loud "bang" sound of the metal plate hitting the ground, the mechanical structure behind the outer wall finally appeared in front of Long Yun; he raised his hand and sang the dust that was stirred up. He waited carefully for a while, and confirmed that there was no combustible substance such as lubricant oil escaped. Then he carried the acetylene blowtorch and carefully studied the complete set of mechanical transmission parts exposed to the light, and then tried to modify and connect.

While observing the opening and closing mechanism of the air gate leaf, Long Yun also lamented how stupid, big, black and thick the things of the Russians were. However, Long Yun had to admit that this flat push mechanism was very reliable, at least it seemed to be able to move around now.

It is different from the soft "black wall" wall material. The alloy positioning pin that should be controlled by an electromagnet is very strong. It took him a lot of time to scrap several grinding wheels before he could barely cut it off. Then he went back to the maz truck and searched. Fortunately, the engineers of the "Roman General Administration" were experienced veterans, and they knew very well what general parts and mechanical assembly were needed in the absence of support. All the things needed could be found. When the diesel engine, friction clutch, transmission and gear link mechanism were ready, and the driving torque should be enough, it was already past nine o'clock in the evening.

In the desert base where there is no trace of people, time does not mean much to Long Yun. When he looked at the watch, he felt it was still early. He stood next to the complete transmission system he had just completed and took a deep breath unconsciously.

The night was cold, and the temperature began to slowly drop into the side of the "black wall" inside the building. The temperature began to slowly drop. The young man who took off his gloves felt the stickiness caused by sweat. His heart was beating faster and his breathing was a little deeper. He knew very well why he felt nervous and excited.

Start the machine, turn the gate pylon, if everything goes well...

With the rumbling opening of the airlock gate, it should be the moment after he faced the "black wall".

After making all preparations, he held the rocker used to start the diesel engine in his hand. His eyes swept over the transmission structure he had just completed and subconsciously checked it again. Long Yun could feel his hand trembling slightly; the sensation of consciousness told him that the mysterious thoughts behind the "black wall" were still fluctuating, and everything seemed to be the same as before, but no one in this world knew what would appear in front of him once the airlock was opened.

Could it be that the sudden increase in the sense of thought, so strong that he died instantly?

Or is it a terrible scene of hell, with the evil breath of death floating in the air?

Or even, Long Yun was almost fantasizing about whether there would be "dead" in this area where the situation was extremely strange and seemed to happen, would there be "dead" quietly hiding behind the "black wall", just waiting for the airlock to open, roaring out, venting violently, showing him the most terrifying hideous face in the world...

The coldness slowly invaded, and unconsciously fought a cold war. Long Yun, who almost had hallucinations, trembled all over. He rubbed his eyes and looked carefully. There was still the airlock gate that had been covered with dust for a long time in front of him, and there was no other abnormality.

In order to explore the secret, it was really time to unveil the mystery of the "dead city", Long Yun was really hesitant. He reviewed the entire action plan repeatedly and checked the oxygen mask, ak-74 assault rifle and other tools several times, and repeatedly confirmed that everything was ready, so he barely suppressed the tension and fear in his heart.

Yes, there is no doubt that this is a deep fear.

Seventeen years ago in the parallel world, all the researchers at the "Roman" base suddenly devoured all the researchers on the "Roman" base on a tragic night. This extremely terrifying power may now be dormant after the "black wall", waiting for the victims to come to the door; looking back at the adventure of entering the "Dead City", although it has not been harmed by mysterious forces so far, what will the situation become if the blocking is lifted?

There was no way to answer this question. Long Yun, who had been standing next to the equipment for a long time and had barely calmed down his mood, slowly took action. He walked to the lamp stand step by step, put on an oxygen mask, picked up the ak-74 assault rifle, and then landed on the starting rod with one hand and activated the diesel engine with the help of compressed air.

What is coming is coming anyway. Since it has reached this point, I can only try it myself.

Abandoning all distracting thoughts and focusing on dealing with the current situation, Long Yun covered his body on the side of the diesel engine that was making a "boom". He barely hid in the tool pile, held the ak-74 firmly in front of him, stabilized his breathing first, and then relaxed the pull rod that controlled the clutch.

As the torque was transmitted, a sharp and sharp metal scraping sound broke out in the open building space, and the heavy airlock looked motionless. Just when Long Yun thought that his work was wrong and wanted to get up to see what was going on, he heard a slight whistling of air. Then a dull "rolling" sound followed. The originally tightly closed airlock gate slightly retreated, and then slowly slid into one wall on one side of the gate with a "rumbling" rumble.

Since the tragedy, the "black wall" that had been covered with for more than ten years has finally been slowly opened by him.

Seeing that the airlock gate was slowly opened, no abnormality was found. Long Yun, who was aiming at the gun, waited carefully for a while, and his ears carefully distinguished the movements around him. However, under the noise of the diesel engine, he could not hear anything, and his ears were full of "rumbling" machines. After hesitating for a while, Long Yun slowly fell to the next side of the diesel engine, turned the switch of the machine, and waited until the diesel engine stopped completely and the noise disappeared, he listened carefully to the surrounding noise again.

There was silence; there was no sound around.

It was late at night, just outside the dark "Black Wall" air gate, Long Yun could only hear the sound of wind coming from afar. Apart from that, there was no abnormal movement. In this deserted forgotten place, after the air gate was opened, no other strange sounds appeared. Instead, because there was an open door hole with a sound absorption effect in front of him, Long Yun, who held the gun in his hand, felt that it was even quieter now than when he first came in.

In this tense silence, Long Yun realized something after a moment. The sensation of consciousness spying is indeed stronger now than before the airlock is opened.

As for his intuitive feeling, the amplitude of this enhancement is not very obvious, but he is still on the side of the wall for the time being and has not really stepped into it. Perhaps the world behind the "black wall" is not enhanced in this way.

So……

The airlock has been opened, what will happen inside the door?

Subconsciously, he held the handle of the ak-74 gun tightly and approached the opened air gate. Long Yun himself didn't know what he was holding the gun, or he had to beware of what was behind the "black wall". He looked into the door through the glass of the oxygen mask, and for a moment he could only see the ground, and the others were all black and could not see clearly.

It seems that since the gate has been opened, I can only go in and find out in person.

Thinking of entering the world behind the "black wall", even Long Yun, who had been through many battles, couldn't help but have a little cold hair. He repeatedly checked the gate and found nothing unusual. He carefully found two high-strength telescopic struts to support the gate opening and closing to prevent any force from resetting the gate, locking himself in, then fumbled to check the equipment on his body, lifted another acetylene blowtorch on the ground, and slowly walked forward into the dark air gate hole.

Step by step, he walked through the slightly sunken air gate, raised the gas lamp and looked around, and found that he had suddenly entered the depressing space of the extreme darkness.

The so-called "extreme darkness" does not mean that there is no light at all, but that there is no background of reflected light around, and the ambient light is too dim, which makes Long Yun's pupil unable to fully adapt for a while. Thinking of this, the young man with his heart pounding and clamps the ak-74 rifle stock on his waist, put his fingers into the trigger guard ring, ready to fire at any time. He slowly adjusted the blowtorch mask to make the light directly into his pupils as weak as possible.

Eliminating the interference of direct light, Long Yun, who had extraordinary vision, gradually adapted to the dim light around him, and he finally slowly saw the situation behind the "black wall".
