Everyone followed Natalia to the gate, where a soldier stood on the left and right of the gate, and at Natalia's signal, the two took out the key and inserted it into the keyholes on both sides of the gate, and then Natalia put her palm on a scanning screen in the center of the gate to scan her palmprints.

After the scan was completed, the two soldiers turned the key at the same time, only to hear a click, the door was divided into two and slowly opened from the middle to the outside, Natalia and the two soldiers took a few steps back, and waited until the gate was fully opened, and then led everyone into the gate.

Wei Dong squinted at the two metal gates, which were nearly 1 meter thick, and Wei Dong couldn't help but wonder in his heart: "So deep underground, such a thick gate, what are they guarding against? Nuclear bombs?"

After everyone entered the gate, the gate slowly closed, and listening to the reverberating click of the gate behind him, Wei Dong's heart became more and more nervous and uneasy.

The scene inside the gate amazed everyone, this is a very large space, the space is visually square, about 100 meters long and wide, about 20 meters high, the walls and ceiling of the space are covered with steel frames, and countless lamps are inlaid on the steel frames to illuminate this space.

And the most terrifying thing for everyone was that between the steel frames, the walls and the roof were covered with weapons, all of which pointed to the middle of the space.

Wei Dong became more and more puzzled in his heart: "These Soviets, as for them, the laboratory was built so deep underground, and they went to great lengths to build such a solid defense structure, and there are still such terrifying weapons here, even if the Americans are powerful, they can't get in!"

Thinking of this, Wei Dong looked back at the others, everyone looked nervous, their feelings should be similar to Wei Dong, but everyone, including Wei Dong, did not ask or express their uneasiness under an inexplicable oppression, and still quietly followed Natalia forward.

After walking out of the section, everyone found that the metal gate was connected to an iron bridge, and the iron bridge was assumed to be in the air about ten meters above the ground in the space, and the other end of the iron bridge was connected to the top floor of a four-story white building built in the center of the space.

Endless questions continued to flash in Wei Dong's mind: "Why do you want to design the passage in the air? Why build such a large space, why build a laboratory in the center of this space, do you want to install the laboratory in a specific environment? If so, then this environment is also space! I really don't understand." ”

Soon, everyone walked along the iron bridge into the door of the building.

The door closes, and inside is a small room, the whole room is white, with occasional red signs or Russian prompts on either side, a series of cubicles on each side, and at the other end of the room stand two staff members in yellow biochemical suits.

Natalia turned around and smiled and said to everyone: "We are about to enter the laboratory, please enter the locker room to change into biochemical clothes, on the left of the man and on the right of the woman, everyone put their clothes and belongings in the cubicle, thank you for your cooperation!" After speaking, Natalia looked at Wei Dong, Wei Dong understood, and nodded at Natalia, meaning that he understood what he said just now.

Everyone entered the locker room and quickly got dressed, all yellow biochemical suits, biochemical suits with hoods, and the face part was a transparent isolation film, through which everyone's faces could be seen, and even so, on the chest of each person's biochemical suit were labeled with everyone's name and specialty, of course, all in Russian.

Natalia also changed into biochemical suits and led everyone to the other end of the room, where the two staff members carefully checked everyone's clothes, and after each inspection, they put one into the door.

After a few minutes, everyone entered the gate, and inside the door was a white passage of about ten meters, the passage was very narrow, probably only two adults could walk side by side, and a row of spouts was installed at the top of the passage.

Natalia turned to everyone and said, "We're going to disinfect everyone here, please follow me slowly." ”

Everyone lined up and followed Natalia forward, the sprinklers above their heads spewing white gas, a scene that reminded Wei Dong of the gas chambers where the Nazis killed Jews.

Soon everyone walked through the disinfection passage of more than ten meters, and the door on the other side of the passage opened, and everyone walked out of the passage under the leadership of Natalia.

What presented to everyone was a different scene, a whole different world compared to the outside.

It was a very spacious room, the room was well lit, the floor was covered with various instruments and equipment, and many staff members were busy in biochemical suits between the equipment.

"This is what scientific research should look like!" Wei Dong couldn't help muttering in his heart.

"We've been waiting for everyone, welcome to the underground test site!"

Suddenly, a man in a biochemical suit stood in front of everyone and shouted, everyone looked into the mask, it turned out to be General Victor, it seemed that he was already here.

"Please come with me and let me show you the miracle!" said Victor, as he walked indoors with Natalia's support.

Following Victor, everyone came to the back of the laboratory, there is a structure like a pillar, there is a door on it, the door opens, everyone walks in, the space inside is very small, just enough to fit Wei Dong and others, after closing the door, Wei Dong knew that this is another elevator, the elevator sinks, about a distance of one or two floors, and soon the door opens.

Outside the door is a wider space than the upper floor, the light in the space is dim, the stairs are gradually downward, and on each floor of the stairs are filled with various equipment and instruments, dozens of workers wearing biochemical suits next to the instruments are busy, this environment is very similar to the satellite launch control center, the only difference is that the only difference is at the front, that is, at the bottom of the stairs is a wide transparent glass wall about six or seven meters wide and two meters high.

Victor led everyone to the glass wall, which was pitch black.

"Everyone, the blue stone is behind this wall, for safety reasons, we have designed this impregnable diamond glass wall to resist the huge energy and radiation from the blue stone, are you ready?"

As he spoke, Victor turned his head to the staff behind him, and the staff turned on the spotlights behind the glass wall.

Under the illumination of the spotlights, we can see clearly that behind the glass is a boxy showroom, the spotlights are arranged in the four corners of the showroom, shining towards the center of the showroom, it is incredible that the showroom is very bright all around, but in the center of the showroom, the place where the lights converge is a cloud of black.

What makes people even more puzzling is that the walls behind this dark shadow are covered with crosses of various sizes, making people wonder if this is a normal science laboratory or a religious place.

The phenomenon behind the glass wall stunned those present, and they all instinctively came to the conclusion that the light disappeared in the center of the showroom, and many questioned why there were so many crosses hanging inside.

Victor begins by explaining the cross: "I'm sure everyone wants to know why there are so many crosses, which is a kind of belief in the past...... Respect, we all have lofty communist beliefs now, please don't care, let's pay attention to this black shadow!"

Victor's perfunctory explanation did not cause everyone to feel uncomfortable, because everyone's attention was almost on the dark shadow, and Victor obviously did not want to stay on the topic of the cross for too long, and then he said proudly: "That's right, the blue stone is in the darkness you see, what does this phenomenon make everyone think of?" Victor stopped and looked at everyone.

At this time, everyone could no longer express their amazement at the phenomenon in front of them, and they stared at Victor one by one.

"Yes, Black Hole!"
