Chapter 1225: Second navigation mark

"Beacon," Zhou Qi said calmly.
"The aviation standards are ready," the soldier answered.
I saw soldiers standing next to the drilling platform to build a signal tower with a height of more than one person. The tower's red and blue lights flash alternately, just like the lighthouse that once led the way back at the air force base.
But this is not an ordinary signal tower, but an underwater sound transmission device equipped with hfg-091 electroacoustic conversion and signal processor.
The array, electronic cabinets and auxiliary equipment are all integrated in this signal tower.
At the same time, when he entered the underground river, Zhou Qi 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 thinking about how to transmit information underwater, sonar equipment has become the most critical tool.
Its most important significance is that when it completes its mission in the week, it will use it to find its way back.
The huge maze of underground water roads is intricate and complex. Humans are cruising in it, and they will lose their direction without realizing it.
Zhou Qi also needs such a reference object to determine his own position.
It is true that Zhou Qi is extraordinary in the water system, and can even breathe through the skin underwater, just like a real frogman.
But he also has his limit. When his mental will is exhausted, Zhou Qi must return to the normal way of survival. At that time, he needs to use his nose and mouth to absorb oxygen again.
In the past, Zhou Qi rarely ventured into underground river basins with undefined terrain because it was too dangerous.
According to Zhou Qi's own estimates, his own mental strength can support him to stay underwater for only two hours.
Therefore, he must have a retreat, otherwise he might stay in the underground river forever.
"Improve the level of martial law," Zhou Qi said: "Everyone, hold 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, which counted down 120 minutes.
The soldier 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 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 lay down your life to save you?"
The soldier stunned: "Because of trust?"
Zhou Qi laughed and scolded: "You are so young, I dare to believe anything."
When the soldier saw Zhou Qi in a good mood, he asked more, "Sir, don't you believe it?"
"Me?" Zhou Qi smiled: "I don't know if I believe it or not."
With that, he drilled into the water with his back and disappeared quickly.
Immediately afterwards, the soldiers dropped the signal tower connected to the safety rope into the pipeline. When the red and blue lights sank to the bottom of the pipeline little by little, it was like a twinkling starlight on the far shore.
This underwater acoustic signal tower will be fixed in the underground river by a safety rope, illuminating Zhou Qi's way home.
...
At this moment, the team of Luo Lan and others have already re-started. Although Wang Run knew that there was definitely a problem with the one that just happened, he could not determine where the problem was.
Time is running short, he can't continue to struggle with Luo Lan on the road.
"Do you think Zhou Qi will proceed according to plan," Xu Qi said: "He has said before that entering the underground river will be dangerous, right, if he can't find a route to retreat, he might die. He loves money like that The desperate man, who has made so much money from Chief Qingzhen in these years, how can he be willing to die in such a place?"
Luo Lan smiled: "If you think he only has money in his eyes, then you have misunderstood him, otherwise you think he is willing to come to Central Plains?"
"Do you believe him?" Xu Qi said: "He is the most important part of this plan, if there is an accident there..."
"Don't worry," Luo Lan shook his head: "I believe in him."
During the talk, the team had reached the artificial intelligence building in barrier 61.
There was only a solitary "zero" black signboard on the top floor of the building, and it seemed that others did not know what artificial intelligence was called.
I saw a large number of Wang's troops stationed around this building, Luo Lan whispered: "Do you feel that this thing is like soldier ants, worker ants arching and guarding the queens, it looks really numb. what."
"A bit like it," Xu Qi nodded.
"It seems that Wang Shengzhi is really going to be gone, and this is the general way to prevent mutiny," Luo Lan pouted. "But I haven't heard of anyone in the Wangs who can initiate mutiny. The power is not tightly controlled. Is it in the hands of Wang Shengzhi?"
"Maybe there is something we don't know," Xu Qi said.
Within barrier 61, centered on the building, black armored vehicles were parked at almost every intersection within a kilometer radius, and temporary machine gun positions were built.
As the convoy passed, all Wang soldiers stared at them coldly, without any expression on their faces.
Some people have been waiting there early in Xiamenkou.
Wang Run got off the bus and said to the third elder Qing: "Mr. Qingzhen, you can only have you, Luo Lan, and Xu Qi in the building this time. The rest of the soldiers should wait outside."
Qing Lao San nodded his head gently. This was what they had expected long ago. His current identity is Qing Zhen, and naturally everything is based on his meaning.
Wang Run continued: "Moreover, before the three go in, they need to go through a security check and change their clothes to enter. Of course, it is not suspected that you are carrying weapons, but that Chief Wang Shengzhi is weak and has weakened immunity. This inspection is only for bacteria."
"Isn't it afraid that we would go in with weapons and say so grandiose," Luo Lan murmured softly.
Wang Run on the side heard this as if he hadn't heard it.
This time Wang invited Qingzhen to come to the Central Plains. In the final analysis, it was carried out with mutual respect.
Wang Shengzhi hoped that Qinghuan could take over the entire barrier alliance in the future, and he should naturally be given equal respect.
After entering barrier 61, although Wang Run received an order to force them over, it was also because Wang Shengzhi didn't have much time.
But during the period of bringing, even if Luo Lan and their team made a lot of mobs, Wang Run did not have a bad word to face. This was all explained by Wang Shengzhi.
Therefore, even now if you want to search for a body check, the security personnel of the building have to find a decent excuse.
Security personnel began to carry out various inspection instruments to the third elder, Luo Lan, and Xu Qi to conduct strict inspections to ensure that they did not bring any dangerous objects into the ground.
At the same time, the three also entered the arranged room and put on clean clothes.
Under this level of inspection, trying to bring dangerous goods into the ground is almost as difficult as reaching the sky, but Qingzhen's plan has long thought of this, so this plan only needs Zhou Qi to cooperate.
Wang Run was waiting outside the door of the room. He looked at Luo Lan, Qing Lao San, and Xu Qi and said, "Please leave me with the three personal belongings for safekeeping. When you leave the ground, I will remain intact. Return everyone."
Luo Lan shrugged: "I just brought a satellite phone with nothing else."
Wang Run said seriously: "The satellite phone must also be handed over to me."
Luo Lan raised his eyebrows: "Why, did Wang treat the guests like this? Our No. 1 and No. 2 characters from Qing's have come to your Wang's site, and even satellite phones have to be taken away. You are guilty. What? Or did you not even plan to negotiate with Kyungs?"
But even when Luo Lan mentioned this, Wang Run did not intend to give up at all: "All the satellite signals underground are blocked. Boss Luo, even if you take this satellite phone down, it has no effect. I don’t know What security can a satellite phone give you, or is there another mystery in this satellite phone?"
Luo Lan said with a smile: "If you don't take it, don't take it."
With that said, Luo Lan actually threw the satellite phone in his hand into Wang Run's arms, and then walked toward the elevator that went straight to the ground.
Behind him, Wang Run asked people to check the satellite phone with technology, but found nothing abnormal.
This made Wang Run a little puzzled. He clearly felt that Qingzhen, Luo Lan and others had another purpose to come to Zhongyuan, but he couldn't figure out where 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. This requires an underwater acoustic system to serve as a navigation mark.
The second point is even more critical, that is how Zhou Qi finds the server unit underground, and he needs someone to enter the location of the server unit underground to guide him.
The equipment cannot be brought underground. The security procedures of the AI ​​Building are rigorous and complicated to the terrible level. However, Qing Zhen has never wanted to rely on equipment to do this. He relies on people.
Xu Qi.
The abilities of transcendental people basically have their own strengths and exist independently.
It is difficult for each other to collaborate with each other, unless they are as lucky as Ren Xiaosu and can bring together Wang Yun with p5092 and Xun Yeyu.
Now, the means Qingqing uses to ensure that Zhou Qi and Xu Qi cooperate with each other is science.
Prior to this, no one except Qingzhen knew that Xu Qi had become an extraordinary person.
As Qing Zhen once said, if you want to give artificial intelligence a heavy blow, then you have to come up with something that does not even include artificial intelligence.
In these two years, Qing Zhen seemed to have thought of how to destroy the server unit under the barrier 61. Since then, this plan has been born.
During this time, Qing Zhen kept a mysterious track, and rarely communicated with the outside world, that is, to prevent artificial intelligence from obtaining enough information from him.
Xu Qi awakened in the follow-up war with Yang, but after Qing Zhen explained, he rarely revealed his ability in front of the outside world, and his ability was also more hidden: control of the voice.
This ability has always been a bit tasteless in the past.
Because Xu Qi could only emit ultrasound waves around 20,300 Hz, he could not directly cause damage to the human body, which is somewhat different from other extraordinary ones.
Even Xun Yeyu, the white and fat little fat man, has great practical ability in war.
What can the 20300 Hz ultrasonic wave be used for? In general, the hertz number of ultrasonic washing machines in civil industry is several times this value.
However, another feature of ultrasonic waves was noticed by Qing Zhen: Ultrasonic waves have extremely strong underwater propagation capabilities.
At this moment, Zhou Qi and Xu Qi reached the most perfect way of cooperation because of the sonar equipment.
Xu Qi is another navigation mark of Zhou Qi.
There is never any useless ability in this world. It can only be seen if you find someone who can use it.
...
Under water, Zhou Qi quickly moved with his sonar equipment in hand. He obviously didn't even swing his legs, but he was as fast as a fish.
The screen on the sonar device looks like an underwater radar, and the green scanning optical axis keeps turning.
The screen showed that just behind Zhou Qi there was a red dot flashing. He knew that it was the beacon of the direction of the sand field.
What he needs to do is to continue in the opposite direction, and then wait for Xu Qi to enter the ground of the artificial intelligence building and release him another navigation mark.
Zhou Qi glanced at the waterproof electronic watch on his hand, and there were 103 minutes left in the countdown.
He calculated in his heart that the real effective time was only 43 minutes, because it would take some time for him to return to the ground, otherwise he would be trapped to the bottom if his mental strength was exhausted.
Therefore, if Zhou Qi still cannot receive the beacon from Xu Qi after these 43 minutes have passed, then he can only return.
On the sonar display device, the green dot represented by Zhou Qi is getting farther and farther from the red dot behind him.
He closed his eyes and continued to move along with the current, trying to ensure that he could stay underwater for a while with minimal mental effort.
There is no trace of external light source in the underground river, only the sonar display device in his hand is like a firefly, wagging.
There is boundless darkness here, but Zhou Qi is not afraid at all. This dark and peaceful environment seems very suitable for thinking.
Indistinctly, Zhou Qi seemed to hear a burst of singing, just like the stream in the back of Ginkgo Hill. Luo Lan sang goodbye friends, everyone.
This is Luo Lan's favorite song, but Zhou Qi always scornfully says that this song is too obscure.
But Zhou Qi had not told Luo Lan, Qing Zhen, and Qing Yi before. In fact, the days when he stole Ginkgo from Ginkgo Hill was the happiest time in his life. At that time, he almost believed in friendship.
The next moment, a new red dot appeared on his sonar display 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, there is the location of the server unit.
Zhou Qi opened his eyes suddenly, but he immediately noticed that something was wrong, because the red dot in front was approaching him at a very fast speed.
He took a subconscious look at his watch and counted down 89 minutes and 12 seconds.
...
When the elevator began to sink quickly, Wang Run's eyes did not squint, and Luo Lan, Qing Lao San, Xu Qi three people suddenly looked into a huge underground space.
Numerous pieces of vacuum glass are embedded on the other side of the underground space. Luo Lan and they seem to have come to the aquarium, except that the aquarium displays fish, but the huge server unit of artificial intelligence is displayed here.
The high-speed flowing underground river naturally becomes the natural cooling external of the unit, and ensures the normal operation of the server.
There is no extra thing here, no decoration, no daily necessities, clean...like the hall cleaned by Qinghuang in Ginkgo Manor.
And very similarly, there are black lakes in both places.
The black lake of Ginkgo Manor is the polished marble floor, and here, there is really a black underground river.
At one moment Luo Lan felt that this black lake seemed to symbolize the other party's thinking, pure and deep.
Qingzhen and Wang Shengzhi also have certain things in common, which is probably the commonality of those who are good at calculating.
Many people are used to ignoring Wang Shengzhi's ability, but in fact, Wang Shengzhi's means of attacking his opponents are more diverse and broader in dimension than Qingzhen's attacks: politics, economy, humanities, popular support, etc. .
At this time, Wang Shengzhi sat alone in a wheelchair, facing the server unit outside the underground space, and did not know what to think.
When he heard the sound of the elevator, he turned around in a wheelchair and smiled weakly: "Welcome three people to visit Wang's masterpiece, artificial intelligence zero. I'm sorry I didn't give you a rest, but my body Can't allow me to continue to delay."
Mr. Qing said: "It doesn't matter, since Wang has already come, it doesn't matter whether you take a break or not. What matters is what kind of agreement Mr. Wang Shengzhi wants to reach with Qing."
Luo Lan carefully observed Wang Shengzhi. Now he is very sure that Wang Run has not lied. Wang Shengzhi may not really have long.
Probably there is still a hint of obsession supporting each other before they can insist on the arrival of "Qingzheng" and Luo Lan.
