Leo turned his head to look at the normal human next to him, obviously he was the only one who could help King Garin decipher the contents and knowledge points of this introduction to cosmology, which also made Leo very curious about what this normal looking human was.

Just as Leo was pondering, a rush of footsteps came in from outside the foyer, and then he saw that the attendant who had arranged for Leo had brought the library manager over for the second time.

In the eyes of the library manager, Leo did not go as mad as he had guessed, but he did not seem to be doing well, as Leo's actions showed that he seemed to be reading a book that he didn't have, and looked at what he was doing from time to time, as if there was a person sitting there.

The administrator didn't know what happened to the people who saw the strange things in the library in the old legends, but none of the people in those legends came to fruition, even those who came into close contact.

Thinking of this, the library manager not only did not come forward to ask Leo what was going on, but pulled the attendant back from the foyer, and then said to the attendant very seriously: "I don't know about this matter, and you don't know either, you just need to serve him like an ordinary attendant in accordance with the rules of the library, as for other things, you don't need to pay attention to it, and you don't need to care." ”

After speaking, regardless of the attendant's reaction, he turned around and left the foyer of the library, leaving only the attendant standing there stupidly, and it took a while for the attendant to return to normal, standing in place for a moment of hesitation, and then cautiously came to the entrance of the forbidden book stack on the second floor, standing far away, without the slightest idea of stepping forward.

Naturally, the small movements of the library manager and the attendant did not escape Leo's perception, and he ignored these things, but focused on the matter at hand.

I saw that he suddenly reported a series of serial passwords to the seemingly normal human in the seat next to him, and after the last symbol of the password came out of his mouth, the seemingly normal human also tried to respond, and reported another serial password.

Leo smiled and was excited when he heard the normal human report the sequence password he had guessed, and after the other party's sequence password came out, he reported another sequence password.

After the password was reported this time, the normal human said: "The identity has been confirmed, the authority has been confirmed, and the secondary management authority has been obtained, and under this authority, the following actions can be performed......"

Hearing the words of the seemingly normal human in front of him, the last trace of doubt in Leo's eyes dissipated, replaced by an excited look.

Just now, Leo carefully analyzed some of the behavior of this human after seeing this human who was invisible to others, and finally judged that this human was not human, but probably some kind of android.

To this end, he used the public identity and secondary permission code of the android that had been made public, and received an immediate response.

The android can be said to be the previous life of the cyborg, the initial appearance of the android was only created by the rich for a special need, but later with the occurrence of some special events, the Earth Federation needs to follow more androids to engage in some low-level services, in order to free up enough population to carry out more important things.

The overall structure of the bionic man is still different from the biochemical man, the bones of the bionic human are a special biological metal, and the muscles, internal organs and skin are also biomimetic materials, almost no different from normal creatures, but the bionic materials are real biomaterials from time to time after all, so from this point of view they are more like robots.

In addition, because of the vigilance of artificial intelligence, the brains installed by the Earth Federation for androids are all brains of low-intelligence systems, and they can only engage in some repetitive and targeted tasks, such as librarians, such as drivers of public transportation, and so on.

In the civilization process of the Earth Federation, the appearance of androids only occupies a short period of time, less than a hundred years before and after, and has little effect on the entire Earth Federation, which also makes the androids only have a short article in the history of science and technology of the Earth Federation, and half of the content of this article is still a public permission code.

After that, the Earth Federation entered a long period of cosmic exploration, and at this time, higher intelligence and more adaptable auxiliary labor were needed to assist human beings in exploring the starry sky, so that cyborgs who had been strictly controlled in terms of lifespan and intelligence, and whose body structure was no different from that of a real person appeared.

Because the android is the predecessor of the cyborg, Leo also paid attention to the relevant information at the beginning, and these materials were naturally recorded, which led to the current permission code.

"Schematic map of the access area. "Leo made sure it was a droid in front of him, and gave the first order of clearance.

As Leo gave the command, the android responded programmatically, and then spread his hand in front of Leo, followed by a holographic projection coming out of his hand, appearing in front of Leo's eyes.

I saw that this holographic projection showed a three-dimensional structure diagram, this structure diagram shows that the place where the android is located is a large library, according to the scale of the facilities marked on the drawing, this library is very large, enough to be called a book city, at this scale estimate, it should be a planet-level super large library.

Leo's focus was not on the facilities of the library, but on the label of the library's holographic diagram, which read the Earth Federation of the First National Library of Thebes.

After seeing this label, Leo couldn't help but be stunned, because in his memory, the star of Thebes had already been destroyed.

Thebes is not prominent among the large and small colonization stars of the Earth Federation, it is neither a habitable immigration star, nor a resource-type containing various precious minerals, this is just a transit station star with a harsh environment, and its biggest role is to provide bearing coordinates for the spacecraft of the Earth Federation in the universe, so as to avoid the waste of resources and manpower by the spacecraft of the Earth Federation because of taking the wrong path.

It's just that even if it's just a transit star, the various facilities here are very perfect, and there are as many as one million people living here, so the facilities that a general colony star should have here are also available, such as this kind of planet-level Central City Library.

However, it is precisely because it is a transit station star, so when the Earth Federation and alien civilizations collide, there will be a large number of attacks against them, in order to cut off the cosmic route of the Earth Federation, and then slow down the reinforcement speed of the Earth Federation.

It was in this environment that Thebes was destroyed in the war between the Earth Federation and other cosmic civilizations, just like thousands of other transit stations.

Leo even remembered the time of the destruction of Thebes, because according to that time, the same day after the past ten Earth years was the first truce between the Earth Federation and an alien civilization, which was recorded in the history books and written in great color.

Under normal circumstances, this First Library should have been turned into cosmic dust along with Thebes, but now it is here.

"Open the city map. Leo thought of this and ordered.

Hearing this, the android answered, and then after a long while, it responded: "Data failure, unable to connect to the city map host, unable to contact the alternate server......"

With a series of unreachable misinformation announced, Leo had already roughly analyzed some of the situation in his mind.

"Turn on the Library Facilities Function Check. Leo commanded again.

This time the feedback information was soon available, and the holographic diagram of the library soon appeared with a large number of red warning signs showing as faults, and only three places in the entire library were well preserved, one was the main library, one was the backup server room, and the last one was the projection network system.

Leo didn't know what the current situation was like with this library, and how it could have overlapped with this forbidden library, but when he saw that the spare server room was still in good condition, he knew that what he wanted to know was settled.

So, he issued another command: "Access the library to monitor the backup data." ”

As his command fell, the hologram in front of Leo's eyes did not appear as he wanted, but instead appeared with the source code data that covered the entire hologram frame and kept moving downward.

Leo was stunned for a moment, and then commanded the android, "Transcode." ”

The android responded, "Transcoding requires first-level permissions. ”

Leo frowned, and then took out the Universal Recorder, controlling the direct recording of those original code data on the holographic image in the form of images, and when he had time, he could write a transcoding program, and he could transform these source code data into city image information.

"The screen is switched to the main library monitoring device. Leo recorded all the source code data, put things away, and then commanded.

However, in the face of this command, the android was silent for a moment, as if a normal person was thinking, and then said to Leo, "The command cannot be executed. ”

Leo asked, "Why? Is it because the authority is not enough?"

The android replied, "The authority is already there, but the instruction violates the third fundamental law of federated intelligent behavior and is classified as a discarded instruction." ”

"The Third Basic Law of Federal Intelligent Behavior?" Leo was stunned, the Basic Law of Federal Intelligent Behavior was so familiar to him, because when he was a cyborg, the top-level authority of his brain database was the Basic Law of Federal Intelligent Behavior, which regulated all his behaviors, even his death behavior.

The third basic law is very simple, that is, it is not allowed to execute any instructions that are harmful to human life, and such instructions will be classified as obsolete instructions, and no authority is allowed to execute them.

Although it was later discovered that there was a loophole in this third cardinal law, and the instruction issuer could bypass this instruction in other ways and let the androids carry out such instructions that harm humans, and the Earth Federation added a supplementary law to make up for the loopholes, but even then it was still full of other loopholes, and eventually this set of Federated Basic Laws of Intelligent Behavior became a set of basic instructions for behavioral norms, and was no longer a law.

Obviously, the basic law of federal intelligent behavior of this android has not been deleted and supplemented, and it is the original basic law of federal intelligent behavior, so it refuses to carry out Leo's instructions on the grounds of the third basic law, that is, when the surveillance screen appears in front of Leo's eyes in the form of a holographic projection, Leo's life will be in danger.

Leo would not think that this was a misjudgment by the android, because according to the strict restrictions on artificial intelligence at that time, any instruction that violated the basic laws would be strictly reviewed and carefully analyzed by all artificial intelligence products, and the rigor of its review and analysis was far from the ritualized audit and analysis of the later cyborgs, so the probability of errors was infinitely close to zero.

Just let people see the images that can kill people, not to mention the world of Velen and Poseidon worlds with various mysterious existences, even in the universe there are not a few similar situations, the spacecraft has to turn on the image masking and modification device on the way to the flight, to screen out those images that are harmful to humans and other ordinary alien races, so that human beings can safely observe the entire universe.

Otherwise, those cosmic observers will either go crazy or die in observation, and there will be no third way.

So Leo thinks that the android's judgment should be right, and the surveillance screen will have a lethal effect, but even if it is right, he does not intend to carry out this judgment, and is still ready to use the way to bypass the third basic law to turn on the surveillance video to see what is going on with the library guard.

The reason why he did this was not because he was not afraid of death, but because he felt that the judgment made by the android might not be applicable to him, because when the android was still in use, there was no psyker in the Earth Federation, and the basic human value in the third basic law of the android was actually analyzed based on the comprehensive quality of ordinary people.

But Leo is now half of a seventh-level psionic person, and the life form level and psionic level have reached an inhuman state, and in the universe, he is a strong man who can fight against the ship alone, and in this case, the image that is fatal to ordinary people may not have any effect on him.

Thinking of this, Leo began to try to use loopholes to bypass the third basic law, and the method he used was very simple, that is, to cover his body with psionic energy to shield all the subtle fluctuations caused by human bodily functions on his body, and disguise himself as an inhuman being.

After all this was done, Leo re-reported a string of identity and permission codes, this time a first-level permission code, as he expected, the permission code passed quickly, and then he directly commanded: "Screen switch, main library monitoring device." ”

This time, the android was silent for a moment, and then did not report any permissions as before, but completely switched the screen to the library's surveillance device, as Leo thought, showing the environment in front of Leo now.
