Time passed slowly. One day later, when Zhang Yuan and others urgently developed countermeasures against digital viruses, the high-speed shuttle troops in front successfully returned and brought back valuable close-up photos.


    These ultra-high definition shooting instruments are all specially processed, coupled with the ultra-high-speed movement of the high-speed shuttle, the possibility of virus is very low. Comparing these photos with the video transmitted by the front-line investigation robot may find more effective data.


    After a while, an exploration force from hemispheric civilization sent another message. They really found a series of data anomalies.


    Located 120 kilometers to the east of TOS civilization base, there is a very strange silver white circular field, which is covered with strange "iron balls".


    These strange iron balls are inlaid on the silver square, with a diameter of about 150 meters and a number of more than 150. The optical properties of these iron balls are very strange. They are almost total reflection and bright, just like a large mercury.


    The most important thing is that the hemispheric civilization exploration robots did not explore this site. When they approached the circular square, they all changed their direction and ran to another place.


    This fact was analyzed after data investigation, because almost all robots made this action, as if they were avoiding this circular place, which seemed quite wrong.


    This fact soon attracted the attention of all staff.


    People began to analyze the photos taken by the high-speed shuttle urgently. These photos are more real.


    Zhang Yuan frowned and quickly browsed through photos. There seemed to be a huge transparent glass cover above the silver square. The hemispheric reconnaissance robot turned its direction 12 kilometers away from the ball, but did not jump out of any wrong information. These things seemed to be covered up by an invisible hand.


    If it weren''t for the photos brought back by the high-speed shuttle, people in the hemisphere might really ignore the silver square.


    "Is the function of digital virus just to let the investigation robot avoid that area? Well... Unlikely. "


    Li Zhendong sat in his seat and whispered, "this thing is not a new military weapon built by the TOS civilization, is it?"


    Zhang Yuan shook his head: "it doesn''t look like it. There''s no weapon like this. It''s a bit like a spaceship... With a curvature engine, a round spaceship is also very good."


    "Why did the machines of hemispheric civilization avoid here?"


    "The reason is still under investigation."


    One of the military experts said, "then send one of our robots to have a look."


    "Have our robots been poisoned?"


    "Yes, that''s why, force it to pass and see what happens?"


    Zhang Yuan nodded and said, "then send a p-113 robot to directly attack the circular square with missiles and launch at an iron ball!"


    Li Zhendong felt and thought, "I remember the p-113 missile, which uses gyroscope navigation."


    "Yes, we need to test the characteristics of this digital virus!"


    After issuing this order, people waited patiently for another 20 hours.


    One high-speed shuttle after another ran to take photos. There is no doubt that these soldiers took great risks. Even high-speed shuttles are at risk of being shot down.


    As a result, a p-113 robot of the new human civilization fired a missile, and the result was unexpectedly crooked! Instead of bombing the circular square, the missile landed in a more remote corner and exploded.


    Then, under the mandatory command of human beings, the robot started its own power engine and rushed like a tank. As a result, when it was 12 kilometers away from the ball, it suddenly stopped and turned its forward direction.


    Not even p-113?


    This fact surprised and frightened everyone.


    If the robots of hemispheric civilization deliberately avoid this area, their technology may not be good, or the robots may have some bugs, because the TOS civilization is really good at electromagnetic interference technology in this field.


    But the robots of new human civilization are prepared for this.


    New human civilization and TOS civilization spend a lot of time together, and they also have scientific and technological exchanges with each other. These robots are unlikely to be completely paralyzed at once, even without any information.


    This big square full of round iron balls, there is a problem, there is a big problem!


    After getting this conclusion, everyone took a breath and was a little excited.


    What people fear is that there is no breakthrough, but now a breakthrough has emerged.


    One of the experts said: "... It is a mysterious weapon we don''t know that paralyzed these robots. According to the information we have collected so far, there are several different reasons. "


    "The first is some kind of electronic interference attack. It may be that after reaching the border of 12 kilometers, the square sent a series of electromagnetic pulses, paralyzing our robots."


    "The second is the attack of physical nature. For example, micro laser. A beam of micro laser trauma is only a few millimeters, but it has been able to substantially damage our robot. As long as a few small holes are made in some key parts, the robot will naturally be scrapped. "


    "Third, as Professor Zhang said, digital viruses are playing tricks! The digital virus may have manipulated the operation of the robot and caused it to fail to a certain extent. "


    "I think the last possibility has the greatest probability!"


    When the expert said the last few words, he was obviously nervous, "but it is still difficult for us to judge the logic behind the outbreak of these digital viruses. Is it to protect the silver round square? What are those iron balls above? "


    "Or are digital viruses launched from these iron balls?"


    Zhang Yuan frowned. Digital virus can be regarded as a dimensionality reduction attack of high-level interstellar civilization on low-level civilization. Because low-level civilizations can''t study it at all. If human beings do not have virtual world technology, they may be as blind as hemispheric civilization, even if they know that there is a huge treasure in front of them.


    Level five or level six civilizations have a deeper understanding of the quantum randomness of intelligent life, so they can create a digital program that can change dynamically.


    This digital program is a bit similar to intelligent life, but it is not real life. If according to human understanding, 1 represents real life and 0 represents non intelligent life, it seems to be an intermediate number between 0 and 1, 0.1, or 0.5. This is a completely unimaginable abstraction.


    These digital viruses can spread through electromagnetic waves, almost everywhere, infecting chips with computing power.


    At present, the only digital virus sample of mankind is the "perpetual bug" virus captured during the war with badit civilization. However, the characteristics of the perennial bug and this new virus are completely different, and there is no way to learn from them.


    If human beings can really control unknown digital viruses, they don''t even need to fully control them. They just need to be able to use them, which is a great progress and can reduce the dimension of the remaining four civilizations.
