"Navigation mark," Zhou Qi said calmly.
"The beacon is ready," the soldier replied.
I saw soldiers setting up a signal tower as tall as a person next to the drilling platform. The red and blue lights on the tower flashed alternately, just like the lighthouse that used to guide the way back at the air force base.
But this is not an ordinary signal tower, but an underwater sound transmission equipment equipped with HFG-091 electroacoustic conversion and signal processor.
The base array, electronic cabinets and auxiliary equipment are all integrated in this signal tower.
At the same time, when Zhou Qi enters the underground river, he will also carry an active sonar device the size of a suitcase to receive the coordinates of the signal tower.
The propagation efficiency of underwater electromagnetic waves is very low, so when Qing was thinking about how to transmit information underwater, sonar equipment became the most critical tool.
Its most important significance is that when Zhou completes his mission, he will use it to find his way back.
The huge maze of underground waterways is so intricate that humans will lose their way without even realizing it when wandering around in it.
Zhou Qi also needs such a reference object to determine his own position.
It’s true that Zhou Qi is a water supernatural being. He can even breathe through his skin underwater, just like a real frogman.
But he also has his limits. When his spiritual will is exhausted, Zhou Qi must return to the way of normal people to survive. At that time, he needs to use his mouth and nose to absorb oxygen again.
In the past, Zhou Qi rarely ventured into underground river basins with unclear terrain because it was too dangerous.
According to Zhou Qi's own estimation, his own mental strength could support him staying underwater for only two hours.
So, he must have a way out, otherwise he may stay in the underground river forever.
"Raise the level of martial law," Zhou Qi said: "Everyone, hold on here, my retreat is in your hands. Check the time. If I don't come back within two hours, you don't have to wait for me. ”
As he spoke, Zhou Qi started the countdown on his waterproof electronic watch, counting down to 120 minutes.
The soldiers will also start the countdown.
When everything was ready, Zhou Qi no longer hesitated. He picked up the active sonar equipment and sat on the edge of the pipe leading to the underground abyss.
At this time, Zhou Qi suddenly asked the soldier in front of him: "Why do you think someone is willing to risk his life to save you?"
The soldier was stunned: "Because of trust?"< /p>
Zhou Qi smiled and cursed: "It's great to be young, I dare to believe anything."
Seeing that Zhou Qi was in a good mood, the soldier asked one more question: "Sir, don't you believe it?" ?"
"Me?" Zhou Qi smiled: "I don't know if I believe it or not."
As he said that, he dived into the water and disappeared quickly.
Immediately afterwards, the soldiers put the signal tower connected to the safety rope into the pipe, with a little red and blue light.When a little bit sinks to the bottom of the pipe, it is like the twinkling stars on the far shore.
This underwater acoustic signal tower will be fixed in the underground river by a safety rope, lighting up Zhou Qi’s way home.
......
At this moment, the convoy of Luo Lan and others had set off again. Although Wang Run knew that there must be something wrong with the incident just now, he could not be sure what the problem was. Where.
Time was running out and he could not continue to tangle with Luo Lan on the road.
"Do you think Zhou Qi will proceed as planned?" Xu Hao said: "He himself said before that entering the underground river would be dangerous, right? If he cannot find a retreat route, he may die. . How can a person like him, who loves money as much as his life, be willing to die in a place like this after making so much money from Chief Qingzhen over the years?"
Luo Lan smiled: "If you? If you think he only cares about money, then you are wrong about him. Otherwise, why do you think he is willing to come to the Central Plains?"
"Do you believe him?" Xu Hao said, "This is his plan? The most important part, if something happens to him..."
"Don't worry," Luo Lan shook his head: "I believe him."
As he spoke, the team was already here. We have arrived at the artificial intelligence building in Fortress 61.
There is only a lonely black sign with the word "zero" on the top floor of the building, as if it is afraid that others will not know what artificial intelligence is called.
I saw a large number of Wang's troops stationed around the building. Luo Lan whispered: "Do you feel that this thing is like soldier ants and worker ants guarding the queen? Look at it. It’s really nerve-wracking.”
“It’s a bit like it,” Xu Mao nodded.
"It seems that old boy Wang Shengzhi is really going to die. This is the only way to prevent mutiny," Luo Lan curled her lips and said, "But I haven't heard that anyone in the Wang family can launch a mutiny. , isn’t the power firmly in Wang Shengzhi’s hands?”
“Maybe there is something inside that we don’t know,” Xu Hao said.
In Barrier No. 61, with the building as the center, black armored vehicles were parked at almost every intersection within a radius of one kilometer, and temporary machine gun positions were set up.
When the convoy passed by, all the Wang soldiers stared at them coldly, without any expression on their faces.
At the entrance of the building, people were already waiting there.
Wang Run got out of the car and said to Qing Laosan: "Mr. Qing Zhen, only you, Luo Lan, and Xu Hao can enter the building this time. The rest of the soldiers please wait outside."
p>Qing Laosan nodded slightly. This was what they had expected. His current identity was Qing Zhen, so naturally everything was subject to his wishes.
Wang Run continued: "Besides, before the three of you go in, you need to go through a security check and change your clothes. Of course, it is not that you are suspected of carrying weapons, but that Chief Wang Shengzhi is weak and has low immunity. This test is done to prevent you from carrying allergens and bacteria. ”
"Aren't you afraid that we would go in with weapons? You said it so grandly," Luo Lan muttered in a low voice.
Wang Run on the side heard this and acted as if he had not heard it.
This time Wang invited Qing Zhen to the Central Plains. In the final analysis, it was done with an attitude of mutual respect.
Wang Shengzhi hopes that Qing Zhen can take over the entire barrier alliance in the future, so he must give Qing Zhen equal respect.
After entering Barrier 61, although Wang Run received an order to forcefully bring them here, this was also because Wang Shengzhi did not have much time.
But during the time they were brought there, even though Luo Lan and his team made a big fuss, Wang Run never said a bad word to him. This was all what Wang Shengzhi had explained.
So, now even if they want to conduct a body search, the building security personnel have to find a decent excuse.
The security personnel began to use various detection instruments to conduct strict inspections on Qing Laosan, Luo Lan, and Xu Hao to ensure that they did not carry any dangerous items underground.
At the same time, the three of them entered the arranged rooms and changed into dust-free clothes.
Under this level of inspection, it would be extremely difficult to bring dangerous goods underground. However, Qing Zhen had already thought of this in his plan, so this plan required Zhou Qi's cooperation.
Wang Run was waiting outside the room door. He looked at Luo Lan, Qing Laosan, and Xu Hao and said, "Please leave your belongings to me for safekeeping until you leave the underground. , I will return it to you intact."
Luo Lan shrugged: "I just brought a satellite phone and nothing else."
Wang Run said seriously. Said: "The satellite phone must also be handed over to me."
Luo Lan raised her eyebrows: "Why, is this how the Wang family treats guests? The number one and number two figures of our Qing family are here. Your Wang family has taken over the territory, and you even want to take away the satellite phone. What are you feeling guilty about? Or are you not planning to have a good negotiation with the Qing family at all?"
But even if Luo Lan said this, , but Wang Run had no intention of giving in: "All the satellite signals underground have been blocked. Boss Luo, even if you take this satellite phone down, it will have no effect. I don't know what sense of security a satellite phone can give you." , Or is there another mystery behind this satellite phone?"
Luo Lan chuckled and said, "If you don't want to take it, just take it."
As he said that, Luo Lan actually said. He threw the satellite phone in Wang Run's arms and walked towards the elevator that led directly to the underground.
Wang Run, who was behind him, had someone use technology to check the satellite phone, but no abnormalities were found.
This made Wang Run a little confused. He clearly felt that Qing Zhen, Luo Lan and others came to the Central Plains for another purpose, but he couldn't figure out what the problem was.
In fact, there were two key points in Zhou Qi’s actions. One was how to return after the mission was completed, which required an underwater acoustic system to serve as a navigation beacon.
The second point is moreThe key is how Zhou Qi finds the location of the underground server unit. He needs someone to enter the location of the underground server unit to guide him.
Equipments cannot be brought underground. The current security procedures of the Artificial Intelligence Building are rigorous and horrifyingly complex. However, Qing Zhen never wanted to rely on equipment to do this. He relied on people.
Hold it.
The abilities of extraordinary people basically have their own strengths and exist independently.
It is difficult for them to cooperate with each other, unless they are as lucky as Ren Xiaosu and can bring Wang Yun, P5092, Xun Yeyu and others together.
Now, the method Qing Zhen uses to ensure that Zhou Qi and Xu Huo cooperate with each other is science.
Before this, no one except Qing Zhen knew that Xu Hao had become a transcendent.
As Qing Zhen once said, if you want to inflict heavy damage on artificial intelligence, you must come up with something that is not even included in artificial intelligence.
In the past two years, Qing Zhen seemed to have already thought of how to destroy the server unit under the 61st barrier. From then on, this plan was born.
During this period, Qing Zhen has always maintained a mysterious whereabouts and rarely communicated with the outside world, in order to prevent artificial intelligence from obtaining enough information from him.
Xu Miao awakened in the subsequent war with the Yang family, but after Qing Zhen confessed, he rarely showed his abilities to the outside world, and his abilities were also more hidden: the ability to control sounds. Take control.
This ability has been somewhat useless in the past.
Because Xu Miao can only emit ultrasonic waves around 20,300 Hz, he cannot directly cause damage to the human body, which is somewhat different from other extraordinary beings.
Even Xun Yeyu, a fair little fat guy, has strong practical application ability in war.
Can you tell me what the 20300 Hz ultrasound can be used for? Under normal circumstances, the Hertz number of ultrasonic washing machines in the civilian industry is several times this value.
However, another characteristic of ultrasonic waves has attracted Qingzhen's attention: ultrasonic waves have extremely strong underwater propagation capabilities.
At this moment, Zhou Qi and Xu Miao reached the most perfect way of cooperation because of the sonar equipment.
Xu Miao is another beacon for Zhou Qi.
There is never a useless ability in this world, it just depends on whether you can find someone who can use it.
......
Underwater, Zhou Qi was moving quickly with a sonar device in his hand. He didn't even swing his legs, but he was as fast as a fish.
The screen on the sonar device is like an underwater radar, with the green scanning optical axis constantly rotating.
The screen showed that a red dot was flashing just behind Zhou Qi. He knew that it was a navigation beacon in the direction of the mud sand field.
What he needs to do is to continue moving in the opposite direction, and then wait for Xu Mao to enter the underground of the artificial intelligence building and release him.Place another beacon.
Zhou Qi glanced at the waterproof electronic watch in his hand and saw that there were 103 minutes left in the countdown.
He calculated in his mind that the real effective time was only 43 minutes, because it would take some time for him to return to the surface, otherwise if his mental power was exhausted, he would be trapped and die underwater.
So, if Zhou Qi still cannot receive the navigation beacon from Xu Hao after these 43 minutes have passed, then he will have no choice but to return.
On the sonar display device, the green dot represented by Zhou himself was getting further and further away from the red dot behind him.
He closed his eyes and continued to move forward with the current, trying to ensure that he could stay underwater for a while with the minimum mental expenditure.
There is no external light source in the underground river, and only the sonar display device in his hand is swaying like a firefly.
There is boundless darkness here, but Zhou Qi is not afraid at all. This dark and quiet environment seems very suitable for thinking.
Vaguely, Zhou Qi seemed to hear a burst of singing, as if Luo Lan was singing "Goodbye, friend" to everyone by the stream in the mountain behind Ginkgo.
This is Luo Lan's favorite song, but Zhou Qi always despises that this song is too unlucky.
But Zhou Qi had never told Luo Lan, Qing Zhen, and Qing Yi before that the days when he stole ginkgo nuts in Ginkgo Mountain were actually the happiest time in his life. At that time, he almost believed it. friendship.
The next moment, a new red dot appeared on the sonar monitor in his arms, right in front of him.
The red dot means that the device has found the signal source. According to the original plan, when the second red dot appears, that is where the server unit is located.
Zhou Qi opened his eyes immediately, but he immediately noticed something was wrong, because the red dot in front was approaching him at an extremely fast speed.
He subconsciously glanced at his watch, which counted down to 89 minutes and 12 seconds.
......
When the elevator began to sink rapidly, Wang Run did not squint, while Luo Lan, Qing Laosan, and Xu Hao suddenly saw the reflection of a huge underground space. Come into view.
Countless pieces of vacuum glass are inlaid on the other side of the underground space. Luo Lan and the others seem to be in an aquarium, except that what is displayed in the aquarium is fish, but what is displayed here is artificial intelligence. Huge server fleet.
The high-speed flowing underground river naturally becomes the natural cooling device of the unit and ensures the normal operation of the server.
There is no redundant object here, no decoration, no daily necessities, clean... just like the hall in Ginkgo Manor that has been cleaned by Qing Zhen.
And what is very similar is that both places have black lakes.
The black lake in Ginkgo Manor is the polished marble floor, and here, there is really a black underground river.
At a certain moment, Luo Lan felt that the black lake seemed to symbolize the other person’s thoughts, pureAnd profound.
Qing Zhen and Wang Shengzhi also have something in common, which is probably the commonality of people who are good at planning.
Many people are accustomed to ignoring Wang Shengzhi’s ability, but in fact, the methods Wang Shengzhi displayed when attacking his opponents were more diversified and broader than Qing Zhen’s attack methods: political, economic , humanities, people's hearts, etc.
At this time, Wang Shengzhi was sitting alone in a wheelchair, facing the server unit outside the underground space, not knowing what he was thinking.
When he heard the sound of the elevator, he pushed his wheelchair and turned around, smiling weakly: "Welcome you three to visit Wang's masterpiece, Artificial Intelligence Zero. I'm sorry for not letting you all take a moment. I need to rest, but my body can’t tolerate me procrastinating any longer.”
Qing Laosan said: “It doesn’t matter, since we have already arrived at the Wang family, it doesn’t matter whether we rest or not, what matters is Mr. Wang Shengzhi. What kind of agreement do you want to reach with the Qing family?"
Luo Lan observed Wang Shengzhi carefully. Now he was very sure that Wang Run was not lying. Wang Shengzhi might not have long left.
Probably because there is still a trace of obsession supporting the other party, he can persist until "Qing Zhen" and Luo Lan arrive.
