Zhang Yuan took a deep breath, put those distracting thoughts behind him, and said loudly: "Let's start, as soon as possible, first cut off a part of the power supply, only keep a small part of the electronic instruments running, and cut off external communications!" ”

The soldiers who followed behind him, after some inspection, directly disconnected the main cable inside the spaceship and the six spare cables. The spacecraft lost power, followed by a soft "click", and the backup battery was reconnected to the power supply, and these original safety designs turned into trouble again.

"Report! We expect to be able to remove all spare batteries and stop most of the equipment in less than 3 minutes! ”

"Got it."

In addition to power outages, the second way to defend against digital viruses is internet isolation, cutting off communications and stopping the spread. This is also a double-edged sword that kills a hundred enemies and damages a thousand. In order to prevent the virus from invading, the headphones, Bluetooth and other communication devices in the power armor were all removed, and communication was quite difficult. Fortunately, there was air inside the spaceship, and the sound could barely be heard, and it could only be communicated through primitive means such as yelling or telegraph.

Without high-tech communications, the level of human warfare regressed to the time of World War I.

Nowadays, people use multi-layered technology to defend against digital viruses, and there is also a certain degree of isolation from the physical level. The detection robot in front first sends the communication signal to the signal base station A, and then the base station A sends it to spacecraft B, and B sends it to C, and there are several detection links in between. Each link has a different way of auditing, different security mechanisms, even if one of them is infected, it will not affect the whole.

Moreover, it is also a question whether the digital virus can spread over ultra-long distances from a distance of tens of astronomical units.

According to the test data of the "10,000-year-old worm" virus, the distance it can spread is only a few light seconds at most. There is a lot of electromagnetic noise in the universe, and the farther away it is, the greater the interference and the weaker the propagation ability.

As for the rest, it would be better to use various technical means of protection.

For example, the "Protective Lock" is a digital virus defense measure developed by Unreal Labs, consisting of a biological brain and 17 physical examination devices, which are installed on almost every supercomputer.

People only know that it can crack the "10,000-year-old bug" very easily, and no one is sure whether it is useful for other digital viruses.

There is also an "overload computing system", which is a technology that eats up all the computing power of a computer in an instant, and kills the "10,000-year-old worm" in an instant by squeezing out the computing power, which is a kind of technology that fights poison with poison.

These technologies are related to the virtual world, which is basically not foreign trade, what is going on on the hemisphere's side, and whether the defensive measures are sufficient, Zhang Yuan is not sure.

After a few minutes, seeing that the power was almost gone, Zhang Yuan said, "Let's start." ”

A staff member took out a special computer from the trunk he carried, connected it to the base station, exhaled deeply, and pressed one of the buttons.

The screen jumped instantly.

It doesn't matter if you don't check the results, you will be shocked when you check it!

Inside many "protective lock" programs, there are strange and complex codes, and these codes are very strange digital signals......

This kind of automatically generated number jumps densely, as if it does not affect the operation of the signal base station itself.

When Zhang Yuan saw this scene, his face turned green, he was shocked and frightened, and several young people who followed behind also bounced in an instant, and hit the deck of the spaceship at once!

"Digital virus, really digital virus!"

At first, they thought it was a bit of a fuss, and they felt that the high-level civilization had made such a big move because of a little suspicion, and they were a little unimpressed, but now, ......

The thought of the possibility of this thing wreaking havoc within civilization made everyone's scalps tingle and cold sweats broke out on their backs.

Now the size of the new human civilization is not the same as before, there are only one or two spaceships, but two battle stars!

If a digital virus is really spreading on the Internet, it will be too difficult to actually extinguish the virus. Moreover, human beings are still in a state of ignorance about this virus, and no one knows what its characteristics are, and when it will completely attack......

"Don't be nervous just yet."

Zhang Yuan swallowed a mouthful of saliva, did a small experiment, and turned on the power of another signal base station again.

The supercomputer was up and running.

After the power is turned off and reconnected, the automatic code generation function inside the "protection lock" disappears, and becomes a series of rigid data......

It shows that these things still follow the fundamentals of digital viruses, and if they are "dead", they cannot be "lived" again.

He turned his head deeply and said loudly, "Turn off all the communication devices inside the spaceship, and use the light signal ......"

"Inform the rear, use the sixth preparation plan!"

Sixth preparation plan?!

A soldier around was stunned for a moment, then immediately saluted and shouted, "Yes!" ”

The sixth preparation plan is the highest level of preparation plan in military exercises, which is specially designed to deal with digital viruses and biological viruses, which is equivalent to the isolation of all the population, the interruption of communications, the cutting off of power supply, and the cessation of almost all industries, leaving only the most basic survival part!

This is quite dangerous for a civilization, losing communication in the universe, and a normal person losing his eyes, ears, mouth, etc., is no different, which means that he can only be beaten but cannot fight back.

Who knows if there are any enemies in this hellish place!

But there is no way, now we have to race against the clock, and a minute late may be really late!

The lights of this small spaceship flashed a few times.

Immediately after that, the rear personnel received the message, and after sending the last message, cut off contact with each other.

The hemispherical scientists on the other base station were dumbfounded, they recognized what the light communication meant, and when they wanted to ask a few more words, they found that the new human civilization had directly pulled the power off. The various lights on the Kyushu began to go out.

They didn't actually detect anything, and everything in their eyes was normal......

Due to the different scientific and technological systems of the two sides, the dispatch of human experts from the past did not come in handy.

"What's going on?"

"Long ...... Sir? Our scientists haven't sent a signal yet. ”

These hemispheres who gathered around to discuss were all in a state of sluggishness.

The economic loss of this kind of power outage is extremely large, especially in many automated industries, once the power supply is disconnected, the entire batch of products will be scrapped, and it takes a lot of manpower and material resources to restart. There are also some people in the elevator room, who may be trapped and cause social chaos.

Prometheus, the leader of the hemispheres, shook his head sharply, now was not the time to think about the economy. Since the new human civilization has begun to shrink, they must also shrink, and if something really happens, their hemisphere civilization will not be able to resist it.

"Pull the gate, and we'll pull the gate too! And let the Karina battle star in the rear also lose power! ”

"Execute, execute!"

"Yes!"

After a burst of chickens and dogs, the battle star "Karina" in the rear of the hemisphere civilization also entered a dark state.

Three huge battle stars, one in front and two in the back, floated in the outer regions of the planetary system, and the originally lively activity place became quiet.

All kinds of weapons have lost their luster, but a body of muscles is useless.

And inside the battle star, it is naturally chickens flying and dogs jumping.

"Emergency evacuation notice, this is not a drill! This is not a drill! ”

"Emergency Evacuation Notice, all personnel evacuated to their respective shelters! Those trapped in the elevator room, please don't panic, the rescue team is coming! ”

"Emergency evacuation notice, this is not a drill!"

"What happened?"

"Leave it alone, just do it!"

The masses of the people didn't even know what was going on, and they all began to take emergency shelter. Luckily, there were many similar drills that were drilled without much confusion. This is also a standard quality requirement for interstellar citizens.

At the communication spacecraft on the front line, Zhang Yuan and others are also constantly checking the characteristics of this new digital virus.

Strangely, it doesn't seem to be very contagious, much weaker than the former "10,000-year-old bug" virus, and the surrounding electronic devices have not been infected on a large scale. I think that the 10,000-year-old insect was paralyzed immediately when it was encountered, but the one I encountered now does not seem to be very contagious.
