The soldier of this famous voice department is called Xie Tian, because their family has three generations of single transmission, to his parents' generation, has not come out, the two elders went everywhere to pray to God and worship Buddha, until the age of forty gave birth to Xie Tian, forty years old in this era can be regarded as a child, so, the two old people have a feeling of thanks, just their family name Xie, so they named their son Xie Tian.

Xie Tian likes military life, but the two elders are reluctant to let him join the army, for fear that he will have an accident. Later, the sonar department recruited people in their hometown, and Xie Tian ran to sign up for the army, but the two elders did not agree, but later learned that this sonar department was not a combat unit, so they reluctantly agreed.

It was Xie Tian's turn to be on duty tonight, in fact, he had already heard an abnormal sound from the bottom of the boat, but because he was inexperienced, he was not sure if there was a situation, and now he heard the sound suddenly became louder, which made him have a very bad feeling, so he decided to report the situation.

"Knock knock", Xie Tian quickly ran to the splint on the upper floor, and came to the office of the sonar department, the air quality in the cabin at the bottom was the worst, the light was dim and stuffy, and it was generally used to store supplies, and few people worked and lived here. Even sonar clubs only go down to the bottom floor when they are on duty, and when they are not on duty, they go back to their dormitories or offices on the upper floor.

Their department ~ chief was in the office with the "Sonar Department" sign hanging at the door, Xie Tian entered the office and was about to report, but found that the two members of the same group were also there. He was taken aback and immediately figured out that the two of them must have also noticed an unusual sound coming from the bottom of the boat, and they came to report it earlier than him.

As he expected, as soon as he saw him coming, one of them said, "Thank God, why are you only here now, it's too slow." "This person's name is Shen Yue, and he is the person in charge of the monitoring work in the front cabin.

Obviously, he also guessed the purpose of Xie Tian's coming here. Xie Tian didn't make an excuse, he went straight to their leader, gave a military salute, and said, "Report to the ~ chief, my subordinates heard an unusual sound coming from the bottom of the boat. ”

The minister~ chief smiled, looked at the two subordinates who came before, and then said to Xie Tian: "Okay, you have all made meritorious contributions tonight, thank God, although you came late, I will count you as a share." Tell me what you heard. ”

"Yes! Department ~ long. At first, there was a 'knock knock' sound, much like the sound of someone chiseling a chisel from the bottom of a boat. The sound is not a single source, but it is relatively dense, but it is far and near, and it sounds as if there are more than 20 sound sources at the same time. ”

Hearing this, the head of the department ~ nodded secretly, Xie Tian can hear so much information, which proves that he has completed the usual training subjects very well, but he is indeed a little sluggish, and he is the slowest among the three people, but this is also related to the fact that he is a recruit.

It is common for a recruit to lack a string in his head, and he is not vigilant enough for some abnormal things, as long as he is allowed to go through it a few more times, he can grow into a qualified sonarman.

But before the minister~ could think about it, Xie Tian continued: "Later, those voices changed. ”

"Changed? How about becoming? The minister~ asked the chief.

"It's a lot louder, like hitting with a lot of force, and it's very different from the chiseling sound we hear in training. But the sound is also much more sparse, as if each stroke has to be separated by a long time. "Thank God.

Hearing this, the head of the department~ his face changed, and the two sonar officers in front of him did not hear the change in the sound at the bottom of the boat because they came up early, and now he was surprised to hear Xie Tian's report. Although he believed that these cement ships would not be scuttled by people, who knew if the Soochow people would come up with some moths, and what if they found a way to destroy the hull of the cement ship?

This is not impossible, there are spears and shields in this world, and there are unbreakable cement ships that can also be destroyed. What you can't imagine yourself may not be what others can't imagine.

"Let's go down and listen." The ministry ~ chief gave an order, and walked out first.

"Ministry~Chief," at this moment, Xie Tian stopped the Ministry~ Chief, who had already raised his feet and walked out of the office door, "Ministry~Chief, should we notify the alert troops first and then go over to listen, otherwise it will be too late if something happens." ”

The ~ chief paused, and before he could speak, one of the other two sonarists patted Xie Tian on the shoulder and said, "Thank God, you are a turtle grandson, do you still need to teach this?" The head of the ministry ~ has already notified the alert troops, maybe they have already taken action now, go quickly, go quickly, if you go slowly, you may not be able to hear your voice. ”

After speaking, he also followed the head of the ministry ~ out of the office, and the head of the department ~ heard someone explain to him, and without saying much, he continued to raise his legs and walk to the bottom of the boat. The sonarman was right, the head of the department ~ had already reported to the alert unit as soon as he received the report from the first sonarman, and it had been a while since Xie Tian came late.

Sooner or later, the sonar crews on the six ships had already heard the abnormal sound coming from the bottom of the ship, and each ship had summed up the abnormal situation on the flagship through mutual communication, and after the analysis of the staff headquarters on the flagship, it had been basically determined that there was an enemy "water ghost" carrying out a sneak attack on the ship.

However, there is one difference between reality and the sonarman's suspicion, that is, the vigilance force has not yet taken action, because they have not yet been able to determine the course of action, and the flagship's combat conference room is still being debated.

The main reason for the argument is that they have a great appetite and want to wipe out the enemy "water ghosts" that will be committed in the future. It's not easy to do that. At first, it was proposed that the "water ghosts" should be used to fight the "water ghosts" of their own side to the bottom of the ship and fight the enemy's water ghosts head-on.

This is the most traditional and basic method, and in the understanding of ordinary people, only "water ghosts" can deal with "water ghosts". The "water ghosts" are hidden under the water, so hidden that people cannot find their whereabouts on the water.

The darkness of the night has infinitely increased this concealment, making the "water ghosts" almost come and go without a trace. If you can't find the traces of the "water ghosts", you can't deal with the "water ghosts".

And the only way to find the "water ghost" is to go down to the bottom of the water. Cruising and groping in the water, half by seeing and half by touching, so that there is the possibility of discovering the other party's "water ghost". That is why only "water ghosts" can be used against "water ghosts".

However, after this operational policy was proposed, it was immediately questioned by many people, and the biggest problem with this operational policy was that the number of "water ghosts" on the six cement ships was not large; judging from the sound of the scuttling of the boats heard by the sonar crews of each ship, the enemy's "water ghosts" numbered at least 100 people, but each cement ship had 10 "water ghosts," and the total number of the six ships was only 60.

The number of "Water Ghosts" on your side is only half that of the enemy. The quantity is not comparable to the enemy, and the quality is not comparable to the estimates. Although I don't want to admit it, Soochow's "water ghost team" is recognized as the strongest among the three countries. The quality and quantity are not as good as others, how can you fight with others?
