"You know the opcode about this?" Sylvia asked Leo as she looked at a strange thing that had been sent from the grocery store just now, and at her half-lightened pocket.

This strange thing is not very large, almost the size of two palms, and the shape looks like a mirror, except that the surface of the mirror is covered with patterns composed of various metal wires, these patterns have no mysterious power, but they are unconventional, and people feel very comfortable to look at.

"I don't know, I'll have to try it to know. Leo said with some uncertainty as he looked at the old Earth era electronics in front of him.

In the memory data, Leo knew that this electronic device was a universal encoder for the Earth Age, and it was mainly used in various large machinery, In terms of medical equipment application writing, if necessary, users can easily reset the running program of a large machine with the module that comes with the encoder, so that a machine originally used for mining can become a fighting machine, and a medical equipment used for surgery can also be turned into internal medicine equipment, in short, this equipment is basically a necessary equipment for engineers in the old earth era.

When he returned from the examination room, Leo saw the device in the grocery store, and according to the owner, it was something that had flowed from the inner city, saying that it was an item from the ancient Qulanxi.

Leo had never used such a device, so it was unclear if the general-purpose encoder would be able to read the data from the metal card in which it was written.

After carefully reviewing the information on how to use this device, Leo found that there were only the most basic instructions for use in those materials, and there was very little content about application coding, only a table of coding correspondence and two examples.

However, this information was enough for Leo, who quickly mastered how to use the device and tried to open it.

As he had guessed beforehand, the device was unresponsive, and it was obvious that the people in Lanxi's inner city would not have taken it out and sold it to the grocery store as an antique if they hadn't seen that the device had broken down. This also proves that this equipment is not an important item in the inner city of Lanxi, otherwise even if the equipment is broken, there are still a large number of parts that cannot be manufactured here that can be used to make replacement parts for other equipment of the same type.

Using the universal tool in the Universal Recorder, Leo turns the device on and then scans the components in the device.

Although in terms of the scientific and technological content of the equipment, there is a civilization gap between the Supreme Council's universal recorder and this encoder in the old earth era that spans dozens of levels, but when the Supreme Council of the Universe made the universal recorder, it considered the applicability of this tool, and after reducing some powerful and unique functions in the tool, it extended the scope of use of this tool, and its scope almost spanned the entire universe of civilizations of all levels.

From the original intra-satellite mechanical civilization to the highest interdimensional civilization, you can find suitable basic tools on this universal recorder, these basic tools can not help these civilizations obtain any advanced civilization technology, but can provide users with convenience that their civilization does not have.

For example, the universal tools used by Leo today include not only mechanical tools to disassemble encoders, but also scanners to scan faults and repairs to repair faults.

After scanning the entire device, the universal recorder instantly simulates the working principle of the encoder, finds the faulty components of the equipment, and repairs the components at the picometer level through the repairer.

In Sylvia's opinion, Leo only used the tool on his wrist to send out a row of gratings, and then swept over a plate with various small pottery shards that had been disassembled from the device, and then reassembled the object and opened it again.

The encoder, which had not worked just now, was immediately activated, and a three-dimensional operation interface appeared on the surface of the encoder.

"Can this thing be used?" asked Sylvia, looking at the scene in front of her.

"It should be fine, I'll try first. Leo followed the method in the user manual and put the metal card in his hand into the operation interface.

The chip data inside the metal plate is immediately read by the encoder, and then displayed in front of Leo in the form of a hologram under the guidance of the encoder's intelligent program.

This hologram not only contains the image module created by Leo's previous scan, but also some other data collected after the body scan, identity information, etc., and all the information related to the text is displayed in the common language of a country in the Old Earth era.

Leo understands the language, and although he is not very proficient in using it, after one or two times, there are no major problems.

At this time, he also began to call up the encoding program and began to re-encode the internal data in the metal plate.

Because it is a product of the old earth era, the governments of the earth at that time still used very basic large database artificial intelligence, the level of artificial intelligence completely depends on the size of the large database, and the geoscientists at that time had great anxiety about artificial intelligence, believing that if artificial intelligence is allowed to develop, artificial intelligence will replace human beings.

Therefore, a series of later artificial intelligence products have added a lot of restrictions, and the use of artificial intelligence will also be restricted in some key places, and the way to use artificial intelligence is always triggered, rather than intelligent active assistance.

It is precisely for this reason that Leo, who has become accustomed to intelligent assistance, has to analyze, crack and re-enter the modified code himself, and the whole process is very slow.

Sylvia on the side watched Leo perform repetitive and tedious operations on the illusory image that appeared in front of her for a while, and soon felt bored, so she said to Leo and left the hotel room to go for a walk outside.

Leo didn't say anything, most of his mind was on the code on the hologram, although it was not difficult for him to analyze, crack and rewrite the code, but the way of re-entering was too backward, far from being able to enter automatically on the machine of the Bachelor's Club.

He can only enter manually through this encoder, and the manual input of the key module is so anti-human that he can't imagine why the original person would design such a logical input button module, as if the designer designed it to torture the user.

It took far longer than he had estimated, and Leo finally changed the status level on his metal plate to the highest level, and with the modification of the academic level, the Universal Recorder also detected a radio wave emitted by the metal plate, followed by another radio wave.

When he cracked the analysis code, he found that it was not enough to modify the identity level in the metal card, but also to connect to the central computer on the Prometheus and modify the identity level information there, and there are two ways to modify it, one is to export and import through the equipment of the Bachelor's Club, and the other is to use the network system that comes with the metal card to connect to the central computer and modify it.

Leo naturally chose the second method first, and only when the second method failed would he choose to sneak into the academy and use the device, and the reason why he was not completely sure about the second method was because he did not know if the network receiving module of the Prometheus's central computer was still functioning normally after so many years.

Things turned out much better than he expected, everything went very smoothly, there was no problem with the identity level of his modified academic certificate, and he was accepted by the central computer smoothly, and now he can be said to be one of the highest-ranking people in the entire Prometheus transformed Lanxi City, at least on the central computer.

Leo turned off the encoder, took the metal card in his hand, looked at it, and hung it around his neck, all he had to do was experiment with the use of the metal card.

At this moment, the door opened, and Sylvia walked in from the outside, and she had a very quaint-looking stone statue in her hand than when she had left.

Leo didn't feel any energy fluctuations from the stone statue, it seems that this stone statue should be an ordinary artifact, but what is not ordinary is that the stone statue is engraved with a symbol that looks like a commercial label, and this symbol Leo recognizes is the original coat of arms of the Belmont family.

"Is this something from your Belmont family?" asked Leo directly after discovering the badge.

"Hmm!" Sylvia nodded and said, "I just stumbled upon the person who sold this thing and said that this thing was made by a Gulansi family living in the inner city of Lanxi, and that family specializes in carving god statues for outsiders from various different god realms, and I think it may be the origin of our Belmont family." ”

Leo easily understood Sylvia's thoughts and said, "You want to go and see it?"

Sylvia nodded and said, "If you don't know, it's fine, now that you know, I'm sure I'm going to take a look, although I don't think it's meaningful, but I just want to see it." ”

Although it would be a waste of some time and even cause some trouble, Leo didn't care, he nodded, stretched out his hand towards Sylvia, and said, "Give me your study card, and I'll give you permission to change your identity now." ”

Because of the previous experience and the code that can be applied, Leo's revision of Sylvia's certificate was very smooth, and it only took less than a third of the time to modify Sylvia's certificate level to the highest level.

"It's that simple?" Sylvia said as she looked at the metal card she had handed back to her.

Leo said, "It's just that you look simple. It's not clear in detail, you just need to know that the identity of the two of us is Lan Xi's higher bachelor now, but it can't be said that it has been successful yet, so let's go to the experiment to see if we already have the authority that a higher bachelor should have. ”

"Where to try?" asked Sylvia.

Leo thought for a moment and said, "Go to the top floor." ”

Although according to the regulations, as long as the basic academic certificate is obtained, every place in the public area up to 90 floors can be entered, and every public area equipment can be used, but in fact, this permission needs to be slightly discounted, for example, the top floor of the twenty-four public areas in Lanxi City is a special area that is not eligible to enter even if you have a basic academic certificate.

In this public area where Leo is located, the top floor is the ninetieth floor, which is where the entrance and exit to the inner city are located, according to the regulations, only locals of Lanxi City, diplomats and clergy with special status, and bachelors who have obtained a certificate of level 10 or higher can enter this area, and in a certain way entering this area is equivalent to entering the inner city, and the procedures required to enter the inner city from this area are just routine, and basically there will be no too difficult review.

To enter the top floor from the ninety-eighth floor, the only way to enter is through ten direct elevators, each elevator has an identity authentication device, bachelors need academic certificates, diplomats need diplomatic certificates, only Lanxi natives do not need any documents, because since they were born, their growth data has been included in the Prometheus database.

There have also been some daring people who tried to climb from the outer wall to the ninetieth floor, so as to blend into the inner city, but in the end, these people did not take it well, no one knew what happened during their climb, only that these people eventually fell from the top and fell into flesh, and even some dependents with unique abilities were not spared, and over time, no one dared to do such opportunistic things again.

After revising the level of the academic certificate, Leo and Sylvia went to the ninety-eighth floor of the public area, and in the process of entering the lower thirty floors to the middle thirty floors, and then entering the upper thirty floors, they also went through two identity checks, and did not encounter any accidents, and the modification of the academic certificate permission level was perfect.

Came to the elevator leading to the top floor, this elevator was empty, Leo directly imitated the actions of a bachelor not far away, put the academic certificate in his hand on a small platform at the entrance, and then the closed elevator door opened smoothly, and he walked in naturally.

Behind him, Sylvia also followed his movements, and passed the inspection of the elevator inspection program smoothly.

The elevator automatically rises after closing the door, and when the door opens again, they have come to the top floor, perhaps because of the lack of people, the space on the top floor looks very large, very empty, and the environment is better, more technological, unlike the bottom because it is a public area, the overall look dirty, like a chaotic town on a marginal planet.

After testing the effect of the modified proof, Leo and Sylvia did not stay on the top floor for long, and returned to the public area, although they could also enter the inner city at that time, but in the state of not knowing the actual situation of the inner city, there would only be some unnecessary errors and problems when they ventured into the inner city, so they would collect some intelligence information related to the inner city as much as possible in the past two days, and when all the useful things in the public area have been explored by them, they will enter the inner city to continue exploring.
