Chapter 728

Zhang Yuan took a deep breath and put those thoughts behind him. He said in a loud voice, "let's start as soon as possible. First of all, cut off part of the power supply. Only a small part of the electronic instruments will be kept running, and the external communication will be cut off!"

Several soldiers who followed immediately after, after some inspection, directly disconnected the main cables inside the spacecraft and six spare cables. The spacecraft was powered off, followed by a "click" sound, and the backup battery was re connected to the power supply. The original safety design turned into trouble.

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

"I see."

In addition to power failure, the second way to resist digital viruses is to isolate the Internet, cut off communication, and stop the spread. It is also a double-edged sword that can kill one hundred enemies and lose one thousand. In order to prevent virus invasion, the earphone, Bluetooth and other communication devices in power a have all been removed, which makes communication very difficult. Fortunately, there is air inside the spaceship, so the sound can be barely transmitted, and it can only be communicated through primitive means such as yelling or telegraph.

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

Now people use multi-level technology to defend against digital viruses, and there is a certain degree of isolation from the physical level. The detection robot in front sends the communication signal to the signal base station a, then the base station a sends it to the spacecraft B, and B sends it to C. There are several detection links in the middle. Every link has different audit methods and 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 a very long distance at a distance of dozens of astronomical units.

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

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

For example, the "protection lock" is a digital virus defense measure developed by the virtual laboratory. It consists of a biological brain and 17 kinds of physical examination devices. Basically, every supercomputer is equipped with this kind of hardware.

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

There is also the "overload computing system", which is a technology that can instantly eat all the computing power of the computer, and kill the "perpetual bug" instantly by crowding out the computing power. It is a technology that uses poison to fight poison.

These technologies are related to the virtual world. Basically, they do not trade with foreign countries. Zhang Yuan is not sure about the situation of hemispheric people and whether the defensive measures are enough.

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

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 we don't check the results. We'll be surprised if we check!

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

This kind of automatically generated digital, closely jump, as if does not affect the operation of the signal base station itself.

When Zhang Yuan saw this scene, his face turned green, and he was scared and frightened. Several young people who followed him jumped up and hit the deck of the spaceship!

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

At the beginning, they thought it was a bit of a fuss. They thought that the high level of civilization had made such a big noise because of a little suspicion. They didn't think it was right. But now

At the thought that this thing might be rampant in the interior of civilization, everyone felt numb on their scalp and cold sweat on their back.

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

If the digital virus is really spread in the Internet, it is too difficult to fight 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 yet."

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 run 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 still follow the fundamentals of digital virus, and "dead" can't "live" again.

He turned his head and said in a loud voice, "turn off all the communication devices inside the spaceship and use the light signals..."

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

Sixth plan for war preparation?!

A soldier around was stunned for a moment, then immediately saluted and cried, "yes!"The sixth preparation plan is the highest level preparation plan in military exercises, which is specially used to deal with digital virus and biological virus. It means that all the population is isolated, communication is interrupted, power is cut off, almost all industries are stopped, and only the most basic survival part is reserved!

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

Who knows if there are enemies in this ghost place!

But there is no way, now we have to race against the clock, one minute later, maybe it's really late!

The light of this small ship flashed so many times.

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

The hemispheric scientists on another base station were just silly. They recognized what light communication meant. When they wanted to ask a few more questions, they found that the new human civilization had turned off the power supply. The lights on the Kyushu began to go out.

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

Because the scientific and technological systems of the two sides are not the same, the deployment of human experts in the past is of little use.

"What's the matter?"

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

All the hemispheric people who gathered to discuss were in a state of dullness.

The economic loss of this kind of switch off power is great, especially in many automation industries, once the power is cut off, the whole 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 lobby who may be trapped, causing social chaos.

Promis, the hemispheric leader, shook his head. Now is not the time to think about the economy. Since the new human civilization began to shrink, they must also shrink. If something really happened, their hemispheric civilization could not resist it.

"Pull the gate, we'll pull the gate, too! And turn off the power to the Kalina Battlestar in the rear! "

"Go ahead, go ahead!"

"Yes

After a while, Kalina, the war star behind hemispheric civilization, also entered a dark state.

Three huge battle stars, one in the front and two in the back, float in the outer region of the planetary system, making the originally lively places of activity quiet.

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

And inside the Battlestar, naturally, it's flying.

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

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

"Emergency evacuation notice, this is not an exercise!"

"What happened?"

"Leave it alone, just do it!"

The people didn't even know what had happened. They all started to take refuge. Fortunately, similar exercises have been trained many times, but there has not been much confusion. This is also 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.

Strangely enough, it seems that its infectious ability is not strong. It is much weaker than the previous "perpetual bug" virus. The surrounding electronic devices have not been infected on a large scale. In the past, when it came to the perennial bug, it was paralyzed immediately. But now, it seems that the infection of this one is not high.
