Hua Yuan: "Who were those people just now?" I didn't notice it at first, and finally Lu Shuang said that someone was behind me and I noticed it. "That can only say that Huayuan, you are still too tender." Lu Shuang: "A few of us came out of the blood pool, and someone followed, starting with a robot, and when we walked less than five hundred meters, we changed people." Seven waves of people have been changed over and over again, and I stopped the three of us to eat something just to leave time for the copper wall, and lead part of the tail first. Even if you can't shake it off, you can spread the tail out. Here we are most familiar, here we are kings. I don't know who is following, I think some of them are for the copper wall, and most of them are for you. Hua Yuan hurriedly said: "What's the use of me? There's no need to do it to me! Huayuan didn't believe in the safety here: "If we go like this, we can get rid of our tails when we come to this small shop"?

"Don't you know what this place is?" Lu Shuang turned around and asked Hua Yuan. Hua Yuan shook his head.

"Hey, hey!" Lu Shuang smiled happily and said, "This is a characteristic of the empire, and this small shop is a key intermediate station. "What? Key? Huayuan asked. Haven't you heard? Lu Shuang continued to explain: "To put it bluntly, this is an underground passage, and there are multiple secret passages in each room of the entire small building, and each space needs to be opened with a key. You pay the little waiter, and the door will be given to us. We can go through a maximum of thirty-two gates, and I don't know if there are more doors to go. I walked there at most a dozen or so roads, and there was no need for any more. After the encryption of the key, the price is different at different levels, the price we go is considered advanced, and the low-level is basically three doors. ”

Lu Qiang shouted to Lu Shuang from behind: "Wait a minute, rest first, or you have to die." Lu Shuang also sat in the dark passage at the same time, and Lu Shuang used this short break time to briefly introduce Hua Yuan: "There are many key intermediate stations, and the production and craftsmanship are different, and the shop we came to is a century-old store." It is hand-made by the master of the mechanism, Zhao, and it is absolutely safe. The scope of pattern Zhao production is wide, there are many channels, the transformation is complex, and the coverage is also comprehensive. The main thing is that the secrecy is also very high, and it is the top of all the key intermediate stations. There are also some traps in the empire designed by Trick Zhao, which have the opportunity to open your eyes. ”

"Why are there many kinds of key intermediate stations?" Hua Yuan asked strangely. "Yes." Lu Shuang nodded and replied in the affirmative: "There are a lot, this is just one of them, the reason why we came here is that the key intermediate station is professional in this business, and the family we came to has mainly made a living from this for generations." There is also the security designed by the master, if you think about what we do most of the time, it is all illegal transactions, not to mention in human society, even in the empire It is also illegal. At the beginning, the ground trading was highly risky, so it was changed to simple authentic trading as a trading place. At the beginning, it was only a single channel, and finally developed to several underground passages to communicate, and then the technology continued to upgrade and develop, more and more large-scale and commercial, demand is the market, safety is steel demand. In order to safely evade arrest, in the end, someone began to study something more advanced, and the multi-layer tunnel could no longer meet the security needs, and this thing came into being. ”

"Alright, let's go." Lu Qiang urged. Hua Yuan followed Lu Shuang up and down. It's like a rat hole, the zigzag hole is sometimes high and sometimes short, and the space is constantly changing, Hua Yuan is a little skeptical about this: "Then they can force this shopkeeper to tell us where we are going, and then go directly to the database, not the same can also find us." ”

Lu Shuang looked back at Hua Yuan and asked Hua Yuan to walk in front of him. "At first glance, you just don't know this mechanism at all, and in theory, it works. It's just..."Lu Qiang added: "You don't see this key, you can only hold it alone." It doesn't work if someone else takes it. All passwords are encrypted randomly, and this key has a very strong matrix sequence. Even if you want to decipher, it will take thirty or forty minutes, and by the time it is cracked, people will have already run away. This key will randomly open the right door for us. The key is sensible, giving that one is the right direction, once you open the right door, the secret path will also open at least thirty-two random doors at the same time, which is used to confuse the pursuers. None of the thirty-three passage doors are in the same place, and as soon as we open the door, the multiplier increases, and the more doors we open farther, the less chance we have of being discovered. We may have to use the key three or seven times, but of course we control the number of times. ”

"But a little." Lu Qiang explained in more detail: "You only know the first door, but you don't know which second door we entered. Lu Qiang said to Hua Yuan while holding the key. The middle station is actually a large three-dimensional maze with multiple layers up and down. Lu Shuang shook his head: "It's not a large-scale three-dimensional maze, but a three-dimensional Rubik's Cube, all the opening and closing are controlled by the key in your hand, and we are climbing up and down now just to change your judgment of this space." counter-judgment to insiders and anti-judgment to outsiders". Lv Qiang: "The details are too specific, and the makers of the organs are completely secret from the outside world. We haven't figured it out yet, but I've just heard that at our level, the second layer of doors is open sixty-seven doors at the same time. ”

Hua Yuan: "How can there be so many doors here?" ”。 Lu Qiang: "There are many large and small doors here, I am for the convenience of walking, and there are many doors that may climb in." I don't know exactly how many. ”

Lu Shuang: "It's just that you have a record, there are many passages, and there are changes in size, tilt angle, rotation direction, space color, and even in an empty room, there is also a breeze and humidity. Even if you have a super memory that can distinguish subtle differences, your cranial nerves are all perceived by this key, and he will quickly change the most subtle differences you remember. You can't keep up with what he has changed, and he will deliberately leave you your mark to charm your judgment. Anyway! This is a genius invention. The entire intermediate station has anti-sealing, anti-detection. I want to find someone here to tell you, just give up, you can't do it at all. The key in our hands is a single independent system, not controlled by anyone. With a next invalidation, we have also talked to Tongqiang before about how to crack this intermediate station passage, but there is no good way. The copper wall is direct, that is, it destroys this place directly. This is the most straightforward approach that everyone recognizes at present. Hopefully, you can find a better way to break this puzzle. ”

"And what if you hack the core database?" Hua Yuan asked rhetorically. "Database!" Lu Shuang smiled: "This organ does not have a core database, the reason why it is called an organ is because the core is a purely mechanical structure, no language is used, and there is no data interaction." Lu Shuang patted the wall of the secret road with his hand. Hear no, no empty sound. Exactly how thick this wall is, no one knows. In order to make the intermediate station safer, each room is controlled by a computer, and this key is used to trigger this large mechanism, which is touched by the computer. The machine just replaces the space and the path in its own mechanical way, and you destroy the computer in this space, and if the computer does not trigger the machine, you will be locked up here forever. ”

Lu Shuang was a little regretful: "It would be nice if Lao Gao was here, this old guy really knows a lot of secrets." I guess Lao Gao knows a lot about this, so if you have a chance, let's go back and ask. Hua Yuan followed Lu Shuang and Lu Qiang in this passage, watching them easily use the key to open one space door after another. Each space is almost the same, there is no change in special color, and there is no change like Lu Qiang and Lu Shuang said. Hua Yuan also felt that the space was constantly changing, four or five people wide side by side had to pass, but some of the space was very narrow and rugged, and some could only allow one person to pass sideways.

Hua Yuan has now fallen from the middle position to the last place, and the huge consumption of physical strength is one of the reasons. And it is here, climbing up and down and going back and forth in the space transformation, Huayuan is a little uncomfortable, the claustrophobic environment of the space, there seems to be no fresh air to blow in. In this way, Hua Yuan walked here in a daze for an hour, passing through different doors. Hua Yuan just felt that the little thing he ate had already been consumed by the vigorous exercise of climbing up and down. The main thing is thirst. The three of them were basically trotting in the secret road, and there was no pause or rest, and Hua Yuan was still muttering in his heart that he didn't know when he would be able to get out.

From the pleasant shopping to the tense and fierce battle, and now the three of them are moving forward rapidly, this series of high-intensity exercises really makes Huayuan a little difficult to cope with in terms of physical exertion. Gradually, he fell from second place to third place, and from third place he broke out of the team. Seeing that Hua Yuan's physical strength may have reached the limit, Lu Shuang also slowed down and changed to slow walking. Lu Qiang waited for Huayuan in the back.

It's not that Hua Yuan is shy, but he feels that he is in his prime, and he should be the most energetic and endurant. I shouldn't have used up all my physical strength so quickly, and I'm embarrassed to ask the two people in front of me to stop and wait, so I can only endure and persevere. Lu Qiang replied in front: "Don't worry, now walk slowly, you can relieve for a while." I'm going out right away, and you don't have to be embarrassed. Huayuan, you have never been a small trader, and you have not let the chengguan chase you. ”

Lu Shuang in front of him also smiled breathlessly and said, "I know about this, Huayuan, let me tell you, when our Lu Qiang was as old as you, people gave him the nickname Scud." No one in the city management of the country has ever caught up with him, and one word is fast. It's just that in a few years, the whole country has been replaced by robot law enforcement, which will be defeated, otherwise I estimate that this reputation can be maintained until now. ”

Hua Yuan also smiled at the end, and saw that Lu Shuang and Lu Qiang in front of him were also sweating profusely. "We've almost passed nine gates, haven't we?" Hua Yuan asked a little breathlessly: "How long will it take to get out of here?" It feels a little depressing here. ”

"Yes! It's almost over, and after holding on for a while, I'm going out. Lu Qiang responded at the front: "I'm not very comfortable here, and I rarely go here to tell you." Hua Yuan also clearly heard that Lu Qiang was also out of breath. Lu Qiang: "We have to go through thirteen gates this time, so it's safer to walk." A few of us killed people inside the empire, this matter may be a big problem, I don't know what it's like outside, and if we go more, we will stay away from the danger point. ”
