One Thousand Two Hundred and Twenty-Five, the Second Beacon

"Beacon," Zhou Qi said calmly.

"The beacon is ready," the soldier replied.

I saw the soldiers set up a signal tower as high as one person next to the drilling platform. The red and blue lights on the tower flashed alternately, just like the beacon that used to guide the way back in the air force base.

But this is not an ordinary signal tower, but an underwater sound transmission device equipped with HFG-091 electro-acoustic conversion and signal processor.

The array, electronic cabinets and auxiliary equipment are all integrated in this signal tower.

At the same time, when Zhou Qi entered the underground river, he also carried a suitcase-sized active sonar device 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.

The most important meaning of it is that when Zhou Qi completes the task, he will use it to find his way back.

The huge underground labyrinth is intricate, and humans cruising in it will lose their way unconsciously.

Zhou Qi also needs such a reference to determine his own position.

It is true that Zhou Qi is a water superhuman, and he can even breathe underwater through his skin, just like a real frogman.

But he also has his limits. When his mental will is exhausted, Zhou Qi must return to the way of a normal person to survive. At that time, he needs to use his nose and mouth to absorb oxygen again.

In the past, Zhou Qi rarely ventured into the underground river basin with unclear terrain, because it was too dangerous.

According to Zhou Qi's own estimation, his own mental power can support him for only two hours underwater.

Therefore, 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."

With that said, Zhou Qi started the countdown of his waterproof electronic watch, counting down 120 minutes.

Soldiers will also start a countdown.

When everything was ready, Zhou Qi no longer hesitated, he picked up the active sonar equipment and sat on the edge of the pipeline 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 give their life to save you?"

The soldier was stunned: "Because of trust?"

Zhou Qi laughed and scolded: "It's so good 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."

Saying that, he dived into the water with his back and quickly disappeared.

Immediately afterwards, the soldiers also put the signal tower connected to the safety rope into the pipeline. When the red and blue lights sank into the bottom of the pipeline little by little, it was like the twinkling of stars on the distant shore.

This underwater acoustic signal tower will be fixed by the safety rope in the underground river, lighting up Zhou Qi's way home.

...

At this moment, the convoy of Luo Lan and others had already set off again. Although Wang Run knew that there must be a problem with the incident just now, he could not determine where the problem was.

Time was running out, and he couldn't continue to entangle with Luo Lan on the road.

"Do you think Zhou Qi will follow the plan?" Xu Xu said, "He also said before that entering the underground river would be very dangerous, right? If he can't find a way to escape, he may die. His love for money is like A man who has made so much money from Chief Qing Zhen over the years, how could he be willing to die in such a place?"

Luo Lan smiled: "If you think he only has money in his eyes, 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 Xu said, "He is the most important part of the plan, if something happens to him..."

"Don't worry," Luo Lan shook his head: "I believe him."

While speaking, the convoy had arrived at the artificial intelligence building in the No. 61 barrier.

There was only a solitary black signboard with the word "zero" on the top floor of the building, as if they were afraid that others would not know what artificial intelligence was called.

Seeing that there were a large number of Wang's troops stationed around this building, Luo Lan whispered: "Do you feel that this thing is like soldier ants and worker ants defending the queen, it looks really numb to the scalp. what."

"It's a bit similar," Xu Xu nodded.

"It seems that the old boy Wang Shengzhi is really going to die. Generally speaking, preventing mutiny is just like this," Luo Lan said with a pouting lip: "But I haven't heard of anyone in the Wang family who started mutiny, and the power is not firmly grasped. Is it in Wang Shengzhi's hands?"

"Maybe there is something we don't know," Xu Xu said.

Inside the No. 61 barrier, 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 the slightest expression on their faces.

At the entrance of the building, someone was already waiting there.

Wang Run got out of the car and said to Mr. Qing, "Mr. Qing Zhen, this time you, Luo Lan, and Xu Gu can only enter the building. The rest of the soldiers please wait outside."

Qing Laosan nodded lightly, this was what they had expected for a long time. His current identity is Qing Zhen, so naturally everything is subject to his will.

Wang Run continued: "Moreover, before the three of you enter, you still need to go through a security check and change your clothes to enter. Of course, it's not that you suspect that you are carrying weapons, but that Chief Wang Shengzhi is weak and has a low immunity. In order to prevent you from carrying allergens and Bacteria, this is the only way to check.”

"Isn't it just that we were afraid that we would carry weapons in? It's so grand," Luo Lan whispered.

When Wang Run on the side heard this, it was as if he hadn't heard it.

This time, Wang's invitation to Qing Zhen to the Central Plains was done with mutual respect in the final analysis.

Wang Shengzhi hopes that Qing Zhen can take over the entire barrier alliance in the future, and naturally he must give Qing Zhen the same respect.

After entering the No. 61 barrier, although Wang Run received an order to force them over, this was also because Wang Shengzhi did not have much time.

But during the period, even though Luo Lan and his team made a lot of trouble, Wang Run didn't say anything bad, which was all explained by Wang Shengzhi.

Therefore, even if they want to search the body, the security personnel of the building have to find a decent excuse.

Security personnel began to use various detection instruments to conduct strict inspections on Qing Laosan, Luo Lan, and Xu Gu to ensure that they did not carry any dangerous items into the ground.

At the same time, the three of them also entered the arranged rooms and changed into clean clothes.

Under this level of inspection, it would be difficult to bring dangerous goods into the ground, but Qing Zhen had already thought of this in his plan, so this plan needed Zhou Qi's cooperation.

Wang Run was waiting outside the door of the room. He looked at Luo Lan, Qing Lao San, and Xu Gu and said, "Please leave the three belongings to me for safekeeping. When you leave the underground, I will keep them intact. Return to you."

Luo Lan shrugged: "I just brought a satellite phone, nothing else."

Wang Run said seriously: "The satellite phone must also be handed over to me."

Luo Lan raised his eyebrows: "Why, is Wang's hospitality like this? Our Qing's No. 1 and No. 2 people have come to your Wang's site, and even the satellite phone has to be taken away. You are guilty. What? Or are you not planning to negotiate with the Qing family at all?"

But even if Luo Lan mentioned this, Wang Run did not intend to back down: "The satellite signals underground are all blocked, Boss Luo, even if you go down with this satellite phone, it will have no effect. I don't know a What kind of security can a satellite phone give you, or is there another mystery in this satellite phone?"

Luo Lan smiled and said, "If you don't bring it, don't bring it."

With that said, Luo Lan threw the satellite phone in Wang Run's arms, and walked towards the elevator that went straight to the ground.

Behind him, Wang Run asked someone to test the satellite phone with technology, but found nothing unusual.

This made Wang Run a little puzzled. He obviously 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 are two key points in Zhou Qi's actions. One is how to return after the mission is completed, which requires an underwater acoustic system to act as a beacon.

The second point is more critical, that 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.

Equipment cannot be brought into the ground. Today's security procedures in the artificial intelligence building are rigorous and complex to a terrifying level. However, Qing Zhen never wanted to rely on equipment to do this. He relies on people.

Xu concealed.

The abilities of the extraordinary are basically different and exist independently.

It is difficult to cooperate with each other, unless they are as lucky as Ren Xiaosu and can bring Wang Yun, P5092, Xun Yeyu and the others together.

But now, the method Qing Zhen used to ensure that Zhou Qi and Xu Hui cooperated with each other was science.

Before that, no one except Qing Zhen knew that Xu Cong had also become an extraordinary person.

As Qing Zhen once said, if you want to deal heavy damage to artificial intelligence, then you must come up with something that does not even count artificial intelligence.

In the past two years, Qing Zhen seems to have long thought of how to destroy the server unit under the No. 61 barrier. Since then, this plan has been born.

During this period of time, Qing Zhen has always maintained a mysterious whereabouts, and rarely communicated with the outside world, just to prevent the artificial intelligence from getting enough information from him.

Xu Xu awakened in the follow-up war with the Yang family, but after Qing Zhen explained, he rarely revealed his ability to the outside world, and his ability was also more hidden: the control of voice.

This ability has always been a bit tasteless in the past.

Because Xu Hsu can only emit ultrasonic waves of around 20300 Hz, he cannot directly cause damage to the human body, which is somewhat different from other extraordinary people.

Even Xun Yeyu, a white and clean little fat man, has a very strong practical application ability in war.

Can you hide what this 20300 Hz ultrasound can be used for? Under normal circumstances, the Hertz number of the ultrasonic washing machine in the civilian industry is several times this value.

However, another feature of ultrasonic waves has been noticed by Qing Zhen: ultrasonic waves have extremely strong underwater propagation capabilities.

At this moment, Zhou Qi and Xu Hu have reached the most perfect way of cooperation because of the sonar equipment.

Xu Concealment was another beacon of Zhou Qi.

There is never a useless ability in this world, you can only see if you can find someone who can use it.

...

Under the water, Zhou Qi was moving fast with a sonar device in his hand. He clearly 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, and the green scanning light axis keeps turning.

The screen showed that there was a red dot flashing right behind Zhou Qi, and he knew that it was the navigation mark for the azimuth of the sand field.

What he needs to do is to continue moving in the opposite direction, and then wait for Xu Hui to enter the ground of the artificial intelligence building and release another beacon for him.

Zhou Qi glanced at the waterproof electronic watch in his hand, and 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 ground, otherwise, if his mental strength was exhausted, he would be trapped in the water.

Therefore, if Zhou Qi still can't receive the beacon from Xu Hsu after these 43 minutes have passed, then he can only return.

On the sonar display device, the green dot represented by Zhou himself is getting farther and farther from the red dot behind him.

He closed his eyes and moved on with the current, trying to keep himself underwater for a while with minimal mental exertion.

There was no outside light source in the underground river, only the sonar display device in his hand swayed like a firefly.

There is boundless darkness here, but Zhou Qi is not afraid at all. This dark and peaceful environment seems to be suitable for thinking.

Vaguely, Zhou Qi seemed to hear a burst of singing, as if Luo Lan sang it to everyone by the stream in the mountain behind the ginkgo tree, goodbye friends.

This is Luo Lan's favorite song, but Zhou Qi always said that this song was too unlucky.

But Zhou Qi didn't tell Luo Lan, Qing Zhen and Qing Yi before. In fact, the days of stealing ginkgo nuts in Ginkgo Mountain were the happiest time in his life. At that time, he almost believed in friendship.

The next moment, a new red dot appeared on the sonar display in his arms, just in front of him.

The red dot means that the device has searched for the signal source. According to the original plan, when the second red dot appears, there is the location of the server unit.

Zhou Qi opened his eyes immediately, but he immediately noticed that something was wrong, because the red dot in front was approaching him at a very fast speed.

He glanced at his watch subconsciously, and counted down 89 minutes and 12 seconds.

...

When the elevator began to sink rapidly, Wang Run didn't squint, while Luo Lan, Qing Laosan, and Xu Gu suddenly saw a huge underground space.

Numerous pieces of vacuum glass were inlaid on the other side of the underground space. Luo Lan and the others seemed to be in an aquarium, but the aquarium displayed fish, but the huge server unit of artificial intelligence was displayed here.

The high-speed flow of the underground river naturally becomes the natural cooling of the unit and ensures the normal operation of the server.

There is no superfluous object, no decoration, no daily necessities, and it is clean... just like the hall in the Ginkgo Manor that was cleaned by Qing Zhen.

And very similar, both places have black lake water.

The black lake of 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 water seemed to symbolize the thinking of the other party, pure and profound.

Qing Zhen and Wang Shengzhi also have something in common, which is probably the commonality of people who are good at calculating.

Many people are accustomed to ignoring Wang Shengzhi's ability, but in fact, Wang Shengzhi's means of attacking his opponents are more diversified and broader than Qing Zhen's attack methods: politics, economy, humanities, people's hearts, etc. .

At this moment, 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, and smiled weakly: "Welcome to the three of you to visit Wang's masterpiece, AI Zero. I'm sorry I didn't let you rest for a while, it's just my body. I can't afford to delay any longer."

Qing Lao San said: "It doesn't matter, since everyone has come to the Wang family, it is not important to rest or not. The important thing is what kind of agreement Mr. Wang Shengzhi wants to reach with the Qing family."

Luo Lan carefully observed Wang Shengzhi, and now he is very sure that Wang Run did not lie, and Wang Shengzhi may not have been around for a long time.

Probably there is still a bit of obsession to support the other party, so that they can persist until "Qing Zhen" and Luo Lan arrive.
