"Alright! You go back and tell your boss that you don't have to send any more books here tomorrow. Leo gave the money for the books to the grocery store clerk who had come to deliver them, and motioned for him to leave.

At this time, Sylvia quickly found the books that Leo hadn't read in the past two days and put them aside, and finally sorted out all the books, she only found three books that Leo hadn't read, and the rest of the books Leo had read in the library in the public area.

Leo picked up the three books and flipped through them briefly, then set them aside.

"You haven't read these three books, have you?" Sylvia asked after seeing Leo's movements.

"I haven't read it, but the content is in other books, so there's no need to read it again. Leo explained briefly and asked, "Do you have any other places to visit here?"

Sylvia shook her head and said, "Let's go! ”

Hearing Sylvia's words, Leo didn't say anything more, and the books and useless sundries in the room didn't bother to clean up, leaving them to the people in the hotel, and then he and Sylvia checked out of the hotel directly, and went directly to the top floor with the modified study card, and began to go through the procedures for entering the inner city.

The process of going through the procedures is also very simple, that is, use a scanner, the scanner at the entrance scans the identity level in the academic card, and the door to the inner city will open when the level is reached, and under normal circumstances, people who can take the elevator to enter the top floor are also considered to have the qualifications by default, and the procedures after that are just routine.

After a casual inspection, Leo passed through the small door at the entrance and entered an internal passageway.

Obviously, the passage was rebuilt from a maintenance passage, which was a bit narrow and could only support up to four people walking side by side, but the security measures inside the passage were very adequate, and Leo had seen a large number of micro-frequency particle emitters on the wall panels above and below the passage.

Although for the Earth Federation, the overall technology of the Old Earth Age is very backward, this does not mean that the scientific and technological products of the Earth Age have no value, in fact, many of the scientific and technological products of the Old Earth Era have been used in the Earth Federation era when Leo was sitting at the time, and the micro-frequency particle emitter is one of the few products of the Old Earth Era that is still on the list of weapons of the Earth Federation.

The application range of micro-frequency particle emitters is very wide, from the micro-frequency particle cutter used for mining ores to the micro-frequency particle beamer used on space warships, all of which are derived from this weapon of the old earth era, which is enough to show that the power of this weapon is very powerful, even if it is placed in the powerful weapons of other cosmic civilizations, it is definitely ranked first.

Seeing these micro-frequency particle emitters, Leo also put away his contempt for the Prometheus' defense system, because he knew very well that with his current strength as a sixth-level psionic person, micro-frequency particles still posed a mortal threat to him.

Sensing Leo's change in mood, Sylvia immediately asked, "What's wrong?"

Leo didn't hide it, pointing to the micro-frequency particle emitter on the wall, explaining the power of this weapon.

Sylvia was also surprised when she heard this, but after hearing Leo mention the world-destroying weapons of the starry sky civilization these days, she obviously had some antibodies to weapons like the micro-frequency particle emitter, and she had never seen a battleship-class micro-frequency particle beamer, so naturally she couldn't have the same awe of the motherland as Leo.

The passage filled with micro-frequency particle emitters wasn't very long, and the two of them walked for a few minutes before they came to the end, which led to the same entrance, and at the end there was also an identity scanner.

After scanning the metal plates of the two people's academic certificates, the door began to open, and an intelligent hologram appeared in front of the two of them behind the door, saying, "Please come with me to change clothes and disinfect your body." ”

The hologram then turned and led the two to a room where they had to change their clothes, where there were several very old disinfection pods, and a set of bachelor's clothes neatly arranged on the shelves next to the cabins.

At this point, the hologram separates two doppelgangers and shows them how to change clothes and disinfect them.

Leo is no stranger to this set, signaled to Sylvia, took off the clothes on his body directly, and entered the disinfection cabin, and a disinfection grating with special energy was immediately shot out on the bulkhead, which was repeatedly illuminated from head to toe several times, Sylvia didn't say anything when he saw this, according to Leo's actions, undressed and disinfected, and then changed into the prepared bachelor's clothes.

After changing into the bachelor's clothes, Sylvia didn't have any special feelings, but felt that this set of clothes had a simple and capable feeling after wearing them, but Leo was different, because after he changed into this bachelor's clothes, he saw the shadow of the Earth Federation clerk's costume from some costume details.

In fact, when he found out that Lanxi City was actually Prometheus, Leo felt very strange in his heart, because according to common sense, the clothes worn by the highest-ranking scholars in Lanxi City should be the clothes of the old Earth era, but now they are wearing clothes with the characteristics of the Earth Federation against common sense, which is really incomprehensible.

Guided by the hologram, Leo and Sylvia walked through the small passage at the other end of the disinfection pod and walked out through a small door that opened, and the moment they walked out, Sylvia was completely shocked by everything in front of her, she had a long mouth, and she didn't know what to say for a long time, and on the side, Leo looked at everything in front of her and had an inexplicable feeling of going home.

The tall metal buildings could not be seen as far as the eye could see, and various levitating cars flew back and forth between these high-rise buildings, and the sky was covered by artificial suns, artificial clouds, and all other earth-related meteorology generated by the weather generation device, all of which reminded Leo of the colony city of the edge galaxy where he was stationed on his first mission.

If the clothes he was wearing made Leo suspect that this city also had the culture and technology of the Earth Federation, then now this city with the application of Earth Federation technology products everywhere completely confirmed Leo's guess.

For example, the climate generator that is now imitating summer showers is a product of the Earth Federation, because most of the colonized planets of the Earth Federation are resource planets, and those planets are not suitable for human habitation, but because those planets have all kinds of resources that human beings need, the Earth Federation will spare no effort to colonize those planets.

Because of the influence of the environment, the colonized cities of the Earth Federation on those planets are either built underground, in a relatively isolated state from the outside world, or they are built a colonial city completely protected by a protective cover, almost completely isolated from the outside environment.

Because of this, in order to be able to create a habitable environment in this closed state, the scientists of the Earth Federation have created a climate generator that mimics the various climatic environments on Earth, even the sun and moon when it changes day and night.

Because of its simplicity and obvious effect, this climate generator has made this device quickly spread in the Earth Federation, and has become the standard device for the Earth Federation's colony stars.

However, this symbol technology of a medium civilization that will only appear in the Earth Federation after tens of thousands of years has appeared in the Prometheus, the highest technological product of the old Earth era, so there are only two possibilities to explain this matter.

One is that after the humans of the Prometheus settled down, they developed technology and developed a technological product similar to the climate generator, and the other is that the humans of the Prometheus got a complete set of colonization technology of the Earth Federation, which means that a colonial fleet carrying all the colonial technology equipment also came here, and fused with the people of the Prometheus, and also fused the technology together.

Compared with the first one, Leo thinks that the second one is more likely, because even if it can develop a technological product such as a climate generator, what about the other technology and civilization products of the Earth Federation in this city?

"Where are we going now?" Sylvia asked, still a little overwhelmed, as she turned to Leo.

Leo thought for a moment and said, "Let's find a place to live first, as originally planned, we should stay here for a few more days." ”

Although it was the first time for the two of them to come to this inner city, it was not difficult to find a suitable place to live here, and they only needed to place the metal plate of the academic certificate on any scanning table in the corridor, and activate the artificial intelligence of the city service system to get a service similar to that of a guide.

Leo didn't find this too new, after all, any of the frontier colonies of the Earth Federation had similar equipment, and Sylvia was very interested in this artificial intelligence, and after getting the information she wanted, she still asked a lot of questions to the artificial intelligence program.

It's just that this AI is obviously still a very rudimentary AI program, and can only provide dogmatic answers to questions that can trigger critical chains, and for those tricky questions, this AI often has only one response, that is, it cannot recognize the content of the problem.

Although Sylvia asked a little childishly nonsense, some of her casual questions did bring some benefits that Leo hadn't anticipated beforehand.

For example, in the process of asking questions, Sylvia asked the artificial intelligence program to obtain the map of the inner city within their permission, and as a result, they got a map of the inner city, a complete map of the inner city, not only including the map of residential areas, but also some forbidden areas on the Prometheus that are not open to ordinary Lanxi people, it can be said that this map is all the areas explored and controlled by the locals of Lanxi.

At that time, when this map appeared in front of the two of them in the form of a holographic image, both of them were surprised, obviously this map should be the top secret of Lanxi City in their opinion, but then they imagined it carefully, and it was not difficult to understand why this was so, because their academic certificate authority level was the highest level in the entire Bachelor's Association, and they were eligible to obtain all the knowledge that Lanxi City knew.

Luckily, Leo and Sylvia were in a very small area, and the people who came and went were too hurried to pay attention to the others, so when the map appeared, they saw the map, but they didn't think much about it, and they didn't see any difference between the map and the one they knew.

"It's much worse than Sarah. Sylvia shook her head slightly and said after she gradually lost interest in this artificial intelligence.

"Sara?" Leo was stunned for a moment, not remembering the origin of the name Sylvia had mentioned.

"It's the castle elves of Saran. Sylvia reminded.

Leo quickly remembered what Sylvia was talking about Sarah, and smiled, saying, "Of course it's a lot worse, hundreds of thousands of years away." This kind of artificial intelligence is only the most basic triggered information chain artificial intelligence, and that Sara already has intelligence similar to that of humans in a certain aspect, and even far surpasses humans in analyzing data. ”

Sylvia didn't fully understand Leo's words, but she could get the general idea, and just as she was about to say something, a loud noise suddenly came from the far side of the city, and she and Leo looked over where the ultrasonic sound came from.

The pedestrians in the surrounding aisles, although they were also frightened by the loud noise, did not show panic, and after looking at the location of the loud noise, they all ignored it and continued their journey, even if the loud noise was heard again later, they did not turn their heads to look more.

Sylvia closed her eyes slightly, as if she was feeling something, and after a while, she said in a deep voice: "I feel the power of the abyss!"

"It is indeed the power of the abyss. Leo also nodded, and quickly analyzed the location of the source of the sound, compared it with the map he had just obtained, and said, "That's the thirty-sixth round." ”

"Thirty-six rounds?" Sylvia looked at Leo with some blankness.

Leo explained as he recalled the relevant information: "It is responsible for handling all dangerous items, which are defined as comforts that can threaten Lanxi City, and it is also the concentration of supernatural power owners in the entire Lanxi City, except for those important scholars and special department supernatural power guards, all the supernatural power owners in the inner city are concentrated there, responsible for cleaning up those dangerous objects that infiltrate the city. As he spoke, he paused suddenly, as if he had found something interesting, and then before Sylvia opened his mouth to ask, he said with a little meaning: "This thirty-sixth game may have something to do with you?"

"What does it have to do with me?" Sylvia looked puzzled, feeling that Leo was joking, it was her first time here.

Leo said with a smile: "According to the information I just got, the director of the thirty-sixth bureau is called Ferenza Belmont, and he is the patriarch of the Belmont family in the city. ”
