As the investigation deepened, the contradictions became more and more numerous.

The remains of the enemy forces of the Toth civilization have not been found.

The in-depth investigation of various things, the full power of the astronomical observation equipment, the wreckage of the spaceship found and the wreckage of the robots on the base are basically the Torth civilization itself.

"Or, the Thoth civilization is overwhelmingly crushed and has no power to fight back...... Either it's really a civil war. ”

Before figuring out the situation, that unknown risk has always existed, and it may even berain the Kyushu in the next second, and people can't be careless.

Fortunately, at present, the "Kyushu" is relatively far away from that area, a full 10-hour speed of light, even if there is any risk, there should be time to react, and you can't just run away without investigating anything......

But this heart-pounding feeling has always been there, as if the risk will grow and increase over time......

During this discussion, suddenly, a flash of inspiration flashed in Zhang Yuan's mind, and he felt that he and the others seemed to have missed something. This omission was extremely important and dangerous, and he immediately followed the glimmer of light and meditated.

"What is the reason for the chaos in the Toth civilization? Isn't our exploration plan too simple? ”

"Let's take a simple scene, a strange phenomenon suddenly appeared on the surface of the colonized planet and was discovered by the Thoth civilization. They began to investigate carefully, and perhaps even more cautiously than we did! ”

"But in the end, there was total chaos...... So much so that a civil war broke out?!"

"Something is wrong, this is absolutely wrong!"

After he figured out the key points, he was so frightened that he immediately stood up from his position and shouted loudly: "Wait a minute, everyone, we must not overestimate ourselves, think that we are safe enough if we do enough measures?" Isn't it because of this mentality that the Torth civilization has collapsed? ”

"Could it be that an unknown enemy has already launched an attack on us? What exactly is the unknown attack method of a Level 5 civilization...... There's only one thing I can think of, a digital virus! ”

Yes, digital viruses were widely used in high-level civilization warfare, which people had heard of in the interstellar trading market.

At the time, it was just a kind of anecdotal gossip, but now, people may actually encounter it!

Everyone in the room was stunned.

Zhang Yuan calmed down the emotions in his heart a little, and continued: "If a digital virus, after infecting the computer, hides itself again, will not destroy the original function, and even hide it from our security inspectors, I don't doubt the level of security personnel...... But in the face of the unknown, we must be cautious, and it is inaccurate to judge other digital viruses with the characteristics of the 10,000-year-old worm virus!! ”

When the worm infects a computer, it will paralyze the computer and then infect it in all directions through communication radio waves.

This feature is so obvious that it is easy to spot, and it is also protected by humans.

But that's not the case with all digital viruses.

Zhang Yuan said loudly: "All in all, the more time passes, the more machines will be infected with latent viruses. Now is not the time to explore, but the time to finally investigate! ”

He almost yelled out the last few words: "Power off, check!" ”

Power-off investigation and start-up investigation are two different levels!

Zhang Yuan's words immediately quieted down the originally lively conference room. The cost of a region-wide outage is undoubtedly enormous. Which of the various safety facilities does not use electricity? What is the difference between being out of power and being blind and deaf and deaf?

Although it is a bit suspicious of fighting wits with the air, in the face of an unknown digital virus that may exist, no matter how careful you are, you should be careful.

"I agree!" One of the leaders of the hemispheric civilization also immediately nodded: "We don't know anything about digital viruses...... This is indeed a unique attack method of a Level 5 civilization, and it is extremely efficient, far superior to other conventional weapons. ”

"That's right, let's do it, we don't have to discuss it anymore, hurry up." When Captain Feng heard the word digital virus, he knocked on the table hard.

At that moment, people cut off all electromagnetic wave communication to the outside world, and began to arrange manpower to check all communication devices.

As for the hemisphere side, experts have also begun to urgently organize, and it is possible that the digital virus has spread along electromagnetic communications. It's just that there aren't enough experts on the human side to reinforce them for the time being.

This is also the trouble of the alliance between the two sides, due to the uneven strength, after discovering the problem, it is a bit of a big tail, and there is no way to do it directly by giving orders like a single civilization. Human beings have virtual world technology and have been studying digital viruses for a while, but hemispheric civilizations do not have them.

Fortunately, this time the hemisphere civilization side was quite cooperative, in the face of an unknown mysterious product, coupled with a living example of the remains of a fourth-level civilization in front of them, no matter how cautious they were, they quickly organized a large number of experts and began to investigate the whole region.

This large batch is really a large batch, there are thousands of people, and all kinds of unrelated professional talents have come over!

Hemispheres don't want to be too careless and provoke such troublesome things.

In the end, Professor Ichiro Yamamoto, who was in charge of this area, had a few more conversations with the leader of the hemispheres, discussed the inspection process, and assigned several expert-level personnel in the past, which made them feel a little relieved.

The "10,000-year-old worm virus" that humans have been exposed to in the past is the product of a war between advanced civilizations millions of years ago. It's just the simplest digital virus, and there are theoretically more complex and comprehensive types. No matter how many battle stars a fourth-level civilization has, it is completely insufficient to fight in front of this thing, and if the protective measures are a little insufficient, it will be paralyzed in minutes.

After 30 minutes, all the electromagnetic receivers were cut off, and people could only use astronomical telescopes to observe the ruins from afar, and at the same time communicate with each other through the simplest lights.

"Let's go, let's go!"

Zhang Yuan took a deep breath and stepped onto a transport spaceship, accompanied by Professor Ichiro Yamamoto, more than a dozen scientists, and seven or eight soldiers. The transport spacecraft has changed from autopilot to manual piloting mode, and all the surface communication rooms have been closed, so it can be seen that the pilot in front of him is also a little nervous.

"Hum", there was a soft sound on the deck, and the tail of the spacecraft spewed out a violent blue plasma, and it took off successfully.

The large communication base station in front, about 5 light-seconds away from the Kyushu battle star, is the signal receiving center of the entire survey force. If you are really infected with the virus, it must be this space base station that is infected first.

The communication stations of hemispheric civilizations are also nearby. Since the communication technology of the two sides is not the same, and the programming language is also different, they can only check each other.

Zhang Yuan is recalling in his heart the various measures taken by the new human civilization to deal with the digital virus......

There are not many ways to deal with digital viruses, and the simplest and most bottom-up method is to cut off the power, so Professor Yamamoto suggested that hemispheric civilizations should directly cut off power if they can't detect anything.

But if the power goes out for too long, the alliance itself is dangerous, maybe there is an enemy who is eyeing you and waiting for you to cut off the power?
