Seeing this, Chen Chen did not let his guard down. Instead, he took a few more steps back.
He still remembered a few jokes in science fiction. One of them went like this:
In science fiction, people from the future would always travel on a spaceship and encounter a planet that was almost identical to Earth. For example, the atmospheric pressure was the same, the air composition was the same, and so on. Only the flora and fauna were different.
Therefore, the crew of these spaceships would wear ordinary clothes and step onto this planet without any protection.
However, "Microbiology" proved that this was a suicidal behavior.
This was because the same natural environment did not mean that the microbial system was the same. After all, humans grew up on Earth. Humans and the countless microorganisms on Earth coexisted and evolved together, finally forming the human immune system today.
In other words, as early as tens of thousands of years ago, humans had evolved an immune system to deal with nature. This immune system was constantly updated along with nature. This was the real reason why humans could live on Earth.
However, if they were to step onto another planet, even if the planet met the requirements of humans in terms of oxygen content and atmospheric composition, the microorganisms on the planet were completely different. The human immune system had never come into contact with these new bacteria and viruses.
Even if most of the bacteria and viruses on this planet were harmless and only one percent of them were harmful, it was still a huge number.
If there were only one or two harmful microorganisms, the human immune system might be able to resist them. However, on a foreign planet, there were more than tens of millions of harmful microorganisms.
There was no doubt that these people were dead meat.
Previously, the USB drive could not transmit any living matter. However, now that the passage had completely turned into a hole, it was obvious that it was allowing people to enter and exit. Therefore, it was very likely that the nature of the USB drive had changed...
"Little X, have the Black Knights outside put on protective suits."
Chen Chen thought for a moment and quickly instructed. At the same time, he said to the clone warrior again, "A0012, retract your hand and turn off the computer."
Following Chen Chen's order, A0012 immediately did as he was told. Sure enough, the moment the computer was turned off, the black hole immediately disappeared.
Seeing this, Chen Chen's heart gradually relaxed.
He first kept A0012 motionless, then left the main control room and waited silently outside the main control room.
After a while, several Black Knights wearing positive pressure protective suits walked in and placed A0012 into the isolation chamber, then dragged it out.
Following that, the main control room was completely locked down. A0012 was also sent to the Spire's laboratory and was released after a series of measurements.
Because the result was that A0012 did not show any signs of microbial infection.
Even so, Chen Chen did not let his guard down. He had the three Black Knights form the USB drive inspection team and enter the main control room again.
At this time, a negative pressure isolation tent had been set up in front of the main control room. Anyone entering or leaving the main control room would have to undergo sterilization. As the Black Knights entered, Chen Chen ordered them to turn on the computer again and click on the movie Chronicle on the USB drive.
Suddenly, the surveillance screen turned black. When it recovered, a pitch-black hole appeared in the surveillance screen.
At this moment, one of the cloned warriors put on the connected camera and walked directly into the black tunnel.
On the monitor, Chen Chen only saw that the cloned warrior seemed to be flattened as it slowly melted into the black circular passage. After that, it completely disappeared before everyone's eyes.
Chen Chen quickly looked at the corresponding camera image of the cloned warrior, only to find that after the warrior entered the black tunnel, the image completely turned into static and there was no signal.
Chen Chen looked at the connected wire on the ground and suddenly ordered, "A0006, pull that wire back a little."
Following Chen Chen's order, one of the cloned warriors bent down and picked up the wire connected to the camera. However, as he picked it up, he found that the wire had been completely cut off...
The cut was as smooth as a mirror, without a trace of being cut as if it had always been like this.
"A person can go in, but why was the wire cut off?"
Chen Chen wore a thoughtful expression and then said again, "The other two will take the handheld camera and enter the tunnel. After you enter, if you see A0012, bring it back. If you can't find it, you must return within five minutes and record everything on the other side of the tunnel."
The remaining two cloned warriors replaced the connected camera with the handheld camera and then walked into the tunnel without hesitation.
In an instant, the entire main control room was empty. The original three people had completely disappeared, leaving only the pitch-black tunnel that still stood there like a black well.
"Sir Godfather, the USB drive has changed!" At this moment, Little X's voice suddenly came.
Chen Chen had specially installed a camera and pointed the image at the USB drive, keeping it in close-up mode. At this time, when Chen Chen heard this, he saw that the starlight on the USB drive had faded significantly and the density was visibly reduced.
"The starlight has decreased by about a third."
"According to the weight of a cloned warrior plus the total weight of the equipment on them, the total weight is 80 kilograms, so the three of them weigh 240 kilograms. The USB drive originally had 1 billion kilowatt-hours of electricity, which can store 833 kilograms of material, as expected..."
Chen Chen made a quick calculation and immediately understood the changes in the USB drive. "In other words, this kind of tunnel doesn't consume energy when it's maintained, but only when material passes through it will it consume energy?"
Just as Chen Chen was thinking, the black tunnel suddenly flashed again. The entire monitor image flickered with static as if it was being interfered with.
However, this phenomenon only lasted for a moment. After a few seconds, the image stabilized again. At this time, Chen Chen saw that the three cloned warriors had returned.
Seeing this, Chen Chen was slightly relieved. Regardless of what was on the other side of the tunnel, at least it proved that the tunnel was not one-way and that it could be used to go back and forth.
Chen Chen was not afraid of other dangers, but he was afraid of going to the other side of the tunnel and not being able to return. That was the most frustrating thing.
With this in mind, Chen Chen looked at the USB drive in another image, only to find that the density of starlight in the USB drive had decreased again, only about a third remained.
Now, it could be confirmed that the starlight was the indicator of the amount of energy.
The three cloned warriors left the main control room after being disinfected. The cameras and other accessories they used were also sealed and sent to the Spire laboratory for testing.
The test results were still the same, there were no abnormal microorganisms. Not only that, but the number of microorganisms on these cameras was pitifully small.
It was as if the black tunnel had filtered all the microorganisms, but after returning to reality and coming into contact with the air, a small number of microorganisms contaminated the cameras.
Of course, this explanation was very far-fetched because there were countless E. coli microorganisms in the human body. Even the trillions of cells that made up the human body were microorganisms. If the tunnel filtered all microorganisms, there was no reason that humans could enter and exit at will.
In that case, there seemed to be only one answer.
The world on the other side of the tunnel was a world without microorganisms...
