Seeing this scene, Chen Chen not only did not relax, but took a few steps back again.

He also remembers several jokes from science fiction, one of which went like this:

In science fiction stories, there will always be people in the future who take a spaceship and encounter a planet with almost the same environment as the earth, such as the same atmospheric pressure, the same air composition, etc., only the animals and plants are different.

So the members of these ships stepped into the planet wearing ordinary clothes and without any protection.

However, Microbiology proves that this practice is a suicidal act.

Because the same natural environment does not mean that the microbial system is also the same, after all, human beings grew up on the earth, and human beings and countless microorganisms on the earth coexist and evolve with each other, and finally form the human immune system today.

In other words, as early as tens of millions of years ago, human beings evolved an immune system to deal with nature, and this immune system is constantly renewed with nature, which is the real reason why human beings can live on earth.

However, if you set foot on another planet, even if the planet meets human requirements in terms of oxygen content and atmospheric composition, the microbes associated with the planet are completely different, and the human immune system has never been exposed to these new bacteria and viruses.

Even if most of the bacteria and viruses on this planet were harmless, only one percent was harmful, that would be a huge amount.

If there are only one or two harmful microorganisms, the human immune system may still be able to resist it, but on a strange planet, there are thousands of harmful microorganisms.

There is no doubt that these people are dead.

It is true that the USB flash drive could not transmit any living matter before, but at this time, the passage has completely become a hole, which obviously has the meaning of letting people in and out, so it is very likely that the nature of the USB flash drive has changed......

"Little X, let the black knights outside put on protective suits."

Chen Chen thought for a moment and quickly instructed, and at the same time he said to the clone warrior again, "A0012, retract your hand, and then turn off the computer." ”

Following Chen Chen's order, A0012 immediately complied, and sure enough, the moment the computer was turned off, the black hole immediately disappeared.

Seeing this scene, Chen Chen's heart gradually relaxed.

He kept A0012 still before exiting the main control room, waiting silently outside the main control room to fetch it.

After a few moments, several black knights wearing positive pressure suits walked in, placed the number A0012 in the isolation compartment, and dragged it out.

Next, the main control room was completely cordoned off, and Designation A0012 was sent to the Spire Labs, where it was released again after some measurements.

As a result, A0012 showed no signs of microbial infection.

However, Chen Chen did not take it lightly, but let the three black knights form a USB flash drive expedition team and enter the main control room again.

At this time, a negative pressure isolation tent has been set up at the entrance of the main control room, and anyone who enters and exits the main control room needs to be disinfected and sterilized.

Suddenly, as the monitoring screen went black, when it was restored again, a pitch-black hole appeared in the monitoring.

At this moment, one of the clone warriors put on a connected camera and walked directly into the black passage.

On the surveillance, Chen Chen only saw that the clone warrior seemed to be flattened, and little by little it merged into the black circular passage, and then completely disappeared in front of everyone's eyes.

Chen Chen hurriedly looked at the camera screen of the corresponding clone warrior, but found that after the other party entered the black channel, the picture completely became a snowflake and lost the signal.

Chen Chen looked at the wire that was dragging on the ground, and suddenly ordered, "A0006, pull that wire back." ”

Following Chen Chen's order, a clone warrior bent down and picked up the wire connected to the camera, but when he picked it up, he found that the wire had been completely broken......

The fracture is as horizontal as a mirror, without a trace of cutting, as if it were originally so.

"People can get in, but why are the wires cut?"

Chen Chen showed a thoughtful look, and then said again, "The remaining two people take the handheld camera, and all enter the passage, if they see A0012 after entering, bring it back, if they can't find it, they must return within five minutes, and record everything on the other side of the passage." ”

The remaining two clone warriors replaced the wired cameras with hand-held cameras, and then walked into the passage without hesitation.

Suddenly, the entire main control room was empty, and the original three people disappeared completely, leaving only the black passage still standing, like a black well.

"Your Excellency Godfather, the USB flash drive has changed!" At this moment, Xiao X's voice suddenly came.

Chen Chen deliberately installed a camera before, pointed the picture at the USB flash drive, and kept it in a close-up state, at this time, Chen Chen looked at it when he heard the words, but found that the starlight on the USB flash drive had faded a lot, and the density was visibly reduced.

"Starlight is about a third off."

"According to the weight of a clone warrior and the total weight of the equipment on his body is 80 kilograms, then the three of them weigh a total of 240 kilograms, and the USB flash drive originally had 1 billion trillion hours of electricity, which can ingest 833 kilograms of substances, and it is really ......"

Chen Chen estimated a little, and immediately understood the changes in the USB flash drive, "In other words, this channel does not consume energy when it is maintained, and only consumes energy when matter passes through?" ”

Just as Chen Chen was thinking, the black channel suddenly flashed again, and the entire monitoring screen flashed with snowflakes, as if it had been disturbed by something.

However, this phenomenon was only for a moment, and after a few seconds, the picture stabilized again, and only then did Chen Chen see that the three clone warriors had returned.

Seeing this scene, Chen Chen breathed a sigh of relief, no matter what the passage was, at least it proved that the passage was not one-way, but could go back and forth.

Chen Chen was not afraid of other dangers, he was afraid that he would not be able to return to the other side of the passage, which was the most devastating.

Thinking of this, Chen Chen looked at the USB flash drive in another picture again, but found that the starlight density of the USB flash drive had decreased again, and only about one-third was left.

Now it is basically certain that those starlights are an indication of the amount of energy.

The three clone warriors left the main control room after being disinfected, and the camera and other pendants they were using were encapsulated and handed over to the Spire Labs for testing.

The results of the assay were still the same, with no anomalous microorganisms present, and not only that, but there were even a pitiful number of microorganisms on the cameras.

It's as if the black channel filtered all the microbes, but it only came into contact with the air after returning to reality, so a small amount of microbes got on the camera.

Of course, this explanation is far-fetched, because there are countless E. coli microorganisms in the human body, and even the trillions of cells that make up the human body are also microorganisms, and if the channel filters all the microorganisms, it makes no sense that humans can go in and out at will.

Then there seems to be only one answer.

That's the world on the other side of the tunnel, a world without microbes......
