Chapter 737

Zhang Yuan took a deep breath and threw those thoughts behind him. He shouted, "let's start. As soon as possible, first cut off part of the power supply, only keep a small part of the operation of electronic instruments, and cut off external communication!"

The soldiers who followed behind directly disconnected the main cables and six spare cables inside the spacecraft after some inspection. The spacecraft was powered off, followed by a "click" sound, and the backup battery was switched on again. These original safety designs turned into trouble again.

"Report! We expect to remove all the backup batteries and stop most of the devices in 3 minutes! "

"I see."

In addition to power failure, the second way to resist digital viruses is to isolate the Internet, cut off communication and prevent transmission. This is also a double-edged sword that kills an enemy 100 and damages itself 1000. In order to prevent virus invasion, the headphones, Bluetooth and other communication devices in power a have been removed, making communication quite difficult. Fortunately, there is air inside the spacecraft, and the sound can be barely transmitted. It can only be communicated by shouting, telegram and other primitive ways.

Without high-tech communication, the level of human war has regressed to the period of World War I.

Now people defend against digital viruses through multi-level technology, which is also isolated to a certain extent from the physical level. The forward detection robot first sends the communication signal to base station a, then base station a sends it to spacecraft B, and B sends it to C. There are several detection links in the middle. Each link has different audit methods and different security mechanisms. Even if one of them is infected, it will not affect the whole.

Moreover, whether the digital virus can spread over a distance of dozens of astronomical units is also a problem.

According to the test data of the "perpetual bug" virus, the distance it can spread is only a few light seconds at most. There are a lot of electromagnetic noise in the universe. The farther the distance, the greater the interference and the weaker the propagation ability.

As for the rest, a better way is naturally to use various technical protection means.

For example, the "protection lock" is a digital virus defense measure developed by the illusory laboratory. It is composed of a biological brain and 17 physical inspection devices. Basically, each supercomputer is equipped with this kind of hardware.

People only know that it can easily crack the "perpetual bug". No one is sure whether it is useful for other digital viruses.

In addition, the "overload computing system" is a technology that instantly eats all the computing power of the computer. It is a kind of technology that instantly kills the "perennial bug" by crowding out the computing power.

These technologies are related to the virtual world and basically do not engage in foreign trade. Zhang Yuan is not sure what happens to the hemispherics and whether the defense measures are sufficient.

After a few minutes, seeing that the power was almost off, Zhang Yuan said, "let's start."

A staff member took out a special computer from the trunk, connected it to the signal base station, took a deep breath and pressed one of the buttons.

The screen jumps in an instant.

It doesn't matter if you don't check the result. You'll be surprised if you check it!

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

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

Zhang Yuan's face turned green when he saw this scene. He was surprised and afraid. Several young people behind him jumped up in an instant and hit the ship deck all at once!

"Digital virus, it's really a digital virus!"

At first, they felt a little fussy. They thought that the civilized high-level made such a big noise because of a little suspicion. They didn't think so, but now

At the thought that this thing might wreak havoc within civilization, everyone felt their scalp numb and their backs kept sweating.

Now the volume of new human civilization is not what it used to be. There are only one or two spaceships, but two war stars!

If the digital virus really spreads wantonly on the Internet, it is too difficult to really put out the virus. Moreover, human beings are still in a state of ignorance about this virus. No one knows its characteristics and when it will completely attack

"Don't be nervous."

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

The supercomputer began to work normally.

After power failure and reconnection, the automatic code generation function inside the "protection lock" disappears and becomes a series of rigid data

It shows that these things also follow the fundamentals of digital viruses, and "dead" can't "live" again.

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

"Notify the rear and use the sixth war preparation scheme!"

Sixth plan?!

A soldier nearby was stunned for a moment, then immediately saluted and shouted, "yes!"

The sixth war preparation plan is the highest level preparation plan in military exercises. It is specially used to prepare for digital viruses and biological viruses. It is equivalent to isolating all the population, interrupting communication, cutting off the power supply, stopping almost all industries and retaining only the most basic survival part!

This is quite dangerous for a civilization. The loss of communication in the universe is no different from the loss of perception of eyes, ears and mouth by a normal person, which means that you can only be beaten but can't fight back.

Who knows if there are enemies in this damn place!

But there is no way. Now we must race against time. It may be really late if we are a minute late!

This is a small spaceship. The lights shine a few times.

Then, the rear personnel received the information and sent the last message, cutting off the contact between them.

The hemispheric scientists on another base station were simply stupid. They recognized what light communication meant. When they wanted to ask a few more questions, they found that the new human civilization was directly switched off. The lights on the Kyushu began to go out.

In fact, they didn't detect anything. In their eyes, all machines are normal

Because the scientific and technological systems of the two sides are different, it is of little use to dispatch human experts in the past.

"What's going on?"

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

All the people in the hemisphere gathered together for discussion were in a dull state.

This kind of switch off and power-off has great economic losses, especially in many automation industries. Once the power is disconnected, the whole batch of products will be scrapped, and restarting requires a lot of manpower and material resources. Some people in the elevator may be trapped and cause social chaos.

Promes, the hemispheric leader, shook his head. Now is not the time to consider the economy. Since new human civilizations are beginning to shrink, they must shrink too. If something really happens, their hemispheric civilization can't resist it.

"Switch off, we also switch off! And let the War Star Karina in the rear also be powered off! "

"Execute, execute!"

"Yes!"

After a while, the War Star "Kalina" behind the hemispheric civilization also entered a dark state.

Three huge battle stars, one in front and two in the back, float in the peripheral area of the planetary system, and the original lively venues become quiet.

All kinds of weapons have lost their luster, but all their muscles are useless.

Inside the war star, naturally, chickens fly and dogs jump.

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

"Emergency evacuation notice, all personnel evacuate to their own shelters! People trapped in the elevator, please don't panic, the rescue team is coming! "

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

"What happened?"

"Leave it alone and just do it!"

The people didn't even know what had happened. They spread their feet and all began to take emergency refuge. Fortunately, similar exercises have been trained many times, but there was not much confusion during them. This can be regarded as the standard quality requirement of interstellar citizens.

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

It is strange that its infectious ability does not seem to be strong, much weaker than the once "perpetual bug" virus, and the surrounding electronic devices have not been infected on a large scale. Like the perennial bug in those days, it immediately paralyzed as soon as it met, but now it seems that the infectivity of this one is not high.
