The hedging strategy is the most difficult point for the robot group to deal with. This strategy is simply the most clever one that a robot designer has ever added. Without this strategy, the evolutionary trap scheme would have been enough to deal with the robot group.

Xiao Yun was also stubbornly blocked from this strategy and could not move forward. Even, even the deception plan adopted by Xiao Yun at the moment could not bypass the restrictions of the separate hedging strategy. Because it has a hard and fast rule that robots, no matter what you are facing, you must have a part of you choose not to believe. Even in the face of the deception plan, even if the virtual world built by the deception plan is extremely real, there will definitely be some robots who choose not to believe it.

If they don't believe it, then they won't go to the sun, and they won't die.

At this moment, the old man directly raised this core question.

Xiao Yun said: "That's right, it's true that as you said, the deception plan cannot bypass the restrictions of the separate hedging strategy, and there will still be some robots that will not be deceived, and the deception plan cannot completely destroy the robots in this universe." But...... What does it matter? ”

Xiao Yun looked at the old man with a smile, but the old man was silent.

After a moment, the old man slowly shook his head: "I'm sorry, I don't understand what you mean. ”

Xiao Yun supported his body with his hands, changed himself into a slightly more comfortable position, and then said: "Don't forget, the purpose of our human civilization is not to completely destroy robots, but to make the robot group not affect us. It doesn't affect us is the most important thing, does it matter if the robot is completely extinguished or not? ”

"Why doesn't it matter?" The old man said, "Even if there is only one robot left, it will multiply and grow in a short time, and at that time, will you repeat the deception plan again?" I wonder if the robot group will still believe this lie after the hedging of the risk? Or do you need to develop a new lie with the same nature but different content? ”

"There is no need to repeat the deception plan, in fact, we don't have to do anything." Xiao Yun shook his head lightly, "You must know that the hedging strategy also has its weaknesses. The way it works is that if the number of robots is too low, then the number is used to ensure that they are hedged separately, and if the number is large, then the proportion is used to ensure that they are hedged separately. Before the execution of the deception plan, the robot legion must have adopted a proportional hedging mode. ”

"So what?" The old man asked.

"Before the deception plan was executed, there were a lot of robots in this universe. According to my personal estimates, this number is at least in the 100,000 terabyte range. Xiao Yun said, "This number is very large, so the hedging strategy will take effect according to the proportion, and the number of robots that choose to hedge will be about 100 billion." These 100 billion robots will not be deceived and will not die. ”

The old man nodded slightly.

"They will continue to replicate themselves in our universe, but ...... Even if they only copied one robot, the number of robots would exceed the maximum number of hedging robots, and for each robot they copied, another robot would choose to believe the lie and fly to the stars to another world. ”

Xiao Yun paused, and then said in an accentuated tone: "In other words, the number of robots is fixed to death, and for every new one born, an old one will die. Deception schemes are like a shackle that they cannot break through, so their number can only be limited to this level forever and can never be increased. Of course, in reality, the method of determining the number of hedging and confirming the number of existing groups will be very complex and far from being as simple as the distance, communication, group calculation mode, etc., but the fundamental principle is unchanged, and the result is also unchanged.

Either way, they will no longer be a problem for human civilization. Because the starry sky is vast, it will take a long time for the remaining 100 billion robots scattered all over the galaxy to gather together, and it will take time to reach the solar system. When they finally arrived in the solar system, human civilization at that time did not know what it would look like.

As for how to finally eliminate these 100 billion robots...... That's not my thing. ”

Xiao Yun let out a long breath and said lightly: "That's the future of human civilization. I believe that as long as human civilization develops for a period of time, it will be very easy to destroy a robot group that is unable to increase the number of 100 billion units and cannot develop its own technology. ”

It also takes a huge amount of robots to develop their own technology. 100 billion units is not enough to meet this requirement. Therefore, when the quantity is locked, it means that the robot's technology is locked. But human civilization is different, and human science and technology will always advance. One is stagnant, the other is progressing, and the technological gap between the two will get bigger and bigger. And the greater the technological gap, the easier it will be to destroy robots.

The old man sighed, "I understand, I understand completely. According to the principle of the deception plan, it is obvious how the Martian civilization destroyed the infinite replication robots in the two South Gate galaxies. ”

Xiao Yun said: "Yes. The original Martian civilization must have destroyed those demons through a deception plan - even if the specific content is different, the principle must be the same. That's why the Martians will leave the words "robots are stupid". The difference is that the Martians are faced with a very low level of robotics, so the difficulty of the deception plan will be reduced. The robot group that our human civilization faces is relatively high-tech, and the difficulty of deception plans is also very high. In general, the difficulty of the deception plan is positively correlated with the technology of the robot group, and the technology level of the robot group is positively correlated with the technology level of the intelligent civilization. ”

"Yes." The old man nodded, "Moreover, the Robot Group will always be less technologically advanced than the civilization that created it. This means that no matter which civilization creates an infinite copy robot, that civilization has the ability to destroy it. Of course, choose the right method. ”

"Do you have any questions about the deception plan?" Xiao Yun asked.

The old man said, "No." ”

"So...... It's up to you to answer my question. Xiao Yun said, "What is it that has copied another of my group?" What purpose do they have? Why did they create something like a robot? Why did the bots let me go instead of killing me in the first place? ”

The old man was silent for a long time before he sighed: "Without your clone, the robot group has nothing to do with you." ”

"Oh?" Xiao Yun expressed doubts.

Xiao Yun has always believed that the creator of the robot legion is a copy of himself, because this is what General Emmerk told Xiao Yun at the beginning.

The old man said, "Those are all fake. ”

Xiao Yun was silent and listened quietly.

"When I was passing through the vicinity of the Raqqa system, I received a strange signal that seemed to describe a mechanism that could replicate itself infinitely. After analysis, I confirmed that the signal was coming from the Raqqa system and the destination was another galaxy, but I happened to be passing by there, so I happened to eavesdrop on this message. I immediately set out for the Raqqa system to try to stop the research and development of these unknown individuals, and along the way began to look for a way to fight the infinite replication robots.

By the time I arrived in the Raqqa system, I found that the robots had gone out of control, and the robot research and development base that was supposed to exist was gone—I suspect that the research and development base and its personnel have all been destroyed by the out-of-control robots. And I also found you who have established a research base on the planet Raqqa.

I tried to warn you, but it was too late, and your base has been overrun by robots. In a hurry, I unleashed my own long-term deception weapon in an attempt to save the people trapped in the base - unlike your deception plan, my weapon will release specially designed signals to interfere with the robot's recognition module, and if successful, the robot will recognize humans as its own kind.

However, the probability of failure of this weapon is high and it is very unstable. As a result, everyone in your base was killed except you, and you escaped because you were lucky enough to be recognized by the robot as your own kind.

After you escaped, I began to investigate the robot incident, but Raqa Star was no longer able to get close, and it is impossible to know who developed the infinite replication robot, where, and by what means. After confirming that the truth could not be found, I began to study ways to destroy the robot group, and began to pay attention to the every move of human civilization.

In the course of my research, I recognized the limitations of my abilities and knew that I could not do anything about it. After that, I began to look for people in human civilization who have the potential to solve this crisis, and after comparing tens of thousands of outstanding computational scientists, I finally chose you. ”

Xiao Yun smiled a little bitterly: "Finally chose me?" Why? ”

"Although you are not the most outstanding academically, you have the kind of potential you need to solve problems. You are strong enough, brave enough that difficulties can't knock you down, and you're dedicated enough. In the case of not much difference between wisdom and knowledge, these traits have become the most important indicators for me to find candidates. "I've been through something similar, and I know how important these traits are to a problem solver. And it turned out that I made the right choice. ”

"You've experienced something similar?" Xiao Yun asked, "What's the matter?" ”

The old man didn't answer Xiao Yun's question, but continued: "After choosing you as the problem solver, I did something. These things include forging challenges against you, fakes that you've ever had a genetic record, fakes an indication of the existence of your clones, and so on. All this is to let the original human civilization government know your importance, believe in you, value you, and provide you with resources. Because I know that without resources and attention, even if you are an immortal, you will not be able to destroy the robot group. ”

Xiao Yun was stunned for a moment, and then laughed: "So that's it, so that's it." I don't have any doubts. ”

So far, the mystery in the hearts of the two has basically been solved.

After a pause, Xiao Yun said again: "There is one more thing that has not been confirmed. That is, whether the people who created the infinite replication robots in the first place are dead. There is no trace of them in the Raqqa system, and it is possible that they fled early. ”

The old man said, "I will investigate this matter." I'll make sure if those people are dead, and if not, where they are now. I couldn't get close to the previous Raqqa system, but now that the deception plan is in effect, I plan to go back to the Raqqa system to look for clues. ”

"Good, good." Xiao Yun nodded, "We must find them." Even if they are dead, know who they are. The robot group has dealt such a huge blow to our human civilization that I want them to be nailed to the pillar of shame in human history even if they die. ”

The old man glanced at Xiao Yun and seemed to have seen through Xiao Yun's heart directly. Xiao Yun said with some sadness: "You must know that my friend and my lover have all died at the hands of robots. I can't let them die like this, I must find out who planned this. ”

The old man said, "Your purpose does not conflict with mine. ”

The old man was silent for a moment, as if thinking about something, and then continued: "Xiao Yun, I invite you to come with me, to go with me to the Raqqa system, and to find the culprit who caused this crisis. ”

Xiao Yun hesitated: "But...... I'm afraid my physical condition doesn't allow it. ”

"It doesn't matter." The old man smiled and said, "I have a deep study of life science, and I have a special medicine that can improve your physical condition." It won't restore you to the same state, but it will at least extend your life by fifty years. With the aid of hibernation equipment, you can live for at least five hundred years - I have been working on this drug since the time you decided to carry out the doping program, but unfortunately, by the time I did, your companions were already dead. ”

Xiao Yun sighed, and then made a decision.

"It's an honor to go with you to find the truth of the matter, I wonder when we will leave?"

The old man said, "Now." ”

The two looked at each other and laughed together.

Five hours later, General Cherf found Xiao Yun gone. This was a very serious accident, and General Cherf and the people searched for several days but could not find Xiao Yun, and finally had to give up.

The self-government still had a lot to do, and General Cherf could not afford to devote much time to it.

Occasionally, in his rare moments of leisure, General Cherf would sit on the ground, looking up at the bright and peaceful starry sky, and wondering, "When will you return, fellow citizens who fled from Earth?" ”

and...... "Xiao Yun, where the hell have you been?" ”
