As soon as this was said, everyone had an ominous premonition. The enemy has come within a hundred nautical miles from them, but they do not know how terrible it is?

Lu Guangbo nodded to himself, which is worthy of the white family. The news was so smart and his observation was extremely meticulous. He found so many things in a short time.

If it's really like what Bai Qifeng said, they just have to go to the place where the other party refers to investigate or surround them, and they may really be able to tear up the nest of each other.

But Tang Yu thought a little, frowned and said, "Uncle Bai, according to what you said, the cherry blossom country has sonar in the range of 100 nautical miles in the northeast, which has spread to our side. Can you tell me what they do with their sonar? Don't they know the sonar will reveal where they are? "

"If there is a base, it should be to expel marine life. After all, if a base is built in the sea or at sea level, we must stop marine life from destroying the base."

Bai explained.

Tang Yu shook his head: "in this case, they can completely reduce the sonar range to less than one nautical mile. They just need to surround their base. They don't need to spread to 100 nautical miles. This wastes energy and risks being found. I don't believe that there are so many people in their base that they need to be within 100 nautical miles To accommodate. "

"Tang Yu, what do you think is the reason?"

When Tang Yu said this, Bai Kaifeng was stunned and began to doubt his theory. Yes, since the sonar is released, why should the other party release the distance of 100 nautical miles for them to find out? Is the other person's head broken?

Tang Yu pointed to the position of Bai Kaifeng's painting before, and said, "if the other party really set up a base in this 100 nautical mile place, there is no reason why Xia state would not know. In this sea area, it is the boundary of Xia state.

It takes a long time to build a base, and it's hard. I don't believe Xia can't find a clue for such a long time. If it doesn't, it only shows that there is something wrong with the people in the eastern naval district. "

"It's reasonable to say that if it's really a base, it can't be built completely in a day, and it's almost impossible to build a long-term construction without being discovered."

Lu Guangbo nodded in agreement: "but, Xiaoyu, how do you explain the dolphin and sonar? Is this not the enemy's attack? "

"No

Tang Yu's eyes were bright and bright, and he analyzed: "Uncle Bai said that the dolphin was hurt by a powerful sonar. I don't think uncle Bai would be wrong. But if I am the enemy, I will never do something that is easily found out by the opponent. Therefore, I believe that this is a smoke bomb. The other party just uses this sonar to attract our attention and let us think in the wrong direction.

Let me take an example. Jin Chenghu should know about this matter sooner or later. After all, they are not idiots. It is only a matter of time before they can discover such a vision. Wait for them to find out, what will they do? "

"Well, I'm afraid they'll think the same way?" Bai Qifeng was shocked and said: "if you really think so, you will certainly go to investigate and even send large troops to the past."

"It's true that, even with anyone's ideas, they will send large troops to the past. If we don't have enough manpower, even if we find someone there, we may be able to escape. It's not worth the loss. "

Tang Yu chuckled and said, "at the same time, if I were from the cherry blossom Kingdom, I would use this method to avoid the large forces of Xia state, turn ashore and sneak into Xia state, or take advantage of the emptiness of the eastern naval area of Xia state, and destroy the eastern naval area."

"It's... Impossible, absolutely impossible!"

Bai Qifeng shook his head in a hurry and said, "I have explored this sea area for many times. There is absolutely no person from Sakura kingdom within the range of 100 nautical miles. If these people want to take advantage of our people being transferred by the sonar, they must hide within the range of 100 nautical miles, or even within 50 nautical miles before they can be sure to sneak in while our military area is empty, but this is absolutely impossible! "

"Uncle Bai, don't say that. How can you be sure that they are not hiding near our base?"

Tang Yu narrowed his eyes and said, "the so-called detection is only a preliminary detection. Can we really not detect anything?"

"We have sonar detection on our side, but it's not destructive. After all, this is our sea area, so it's better not to damage the ecological environment." Bai Qifeng seriously said: "so, this is absolutely not."

"No, the more you say that, the more you make me believe it is."

Tang Yu said with a smile, "some things, such as sonar and radar, can't be detected. For example, what about stealth submarines? Can you really detect this stealth submarine made of materials that ignore sonar frequency? "

"Stealth submarine?"

As soon as he said this, Bai Qifeng, Lu Guangbo and others all exclaimed in surprise and were greatly shocked. Yes, they didn't think of it. If the other side really uses the stealth submarine, it is very likely to hide in a place very close to them now!"Xiaoyu, if it's really like what you think, what should we do?" Lu Guangbo changed his face and said anxiously, "it's necessary to let Jin Chenghu know about it, otherwise there will be endless troubles."

"Don't worry, old man. All this is our analysis and conjecture, and there is no substantial evidence, how to say? What's more, do you think if you just tell Jin Chenghu, Jin Chenghu will believe it? "

Tang Yu said lazily, "don't worry about it. Jin Chenghu is the commander-in-chief here. Even if we do, what can we do if they don't give us soldiers? The surprise troops of the other side are all experts. If some ordinary soldiers go up there, they will be killed. There is no need for us to wait here.

What's more, you are not under their jurisdiction now, so don't worry about it. Just do our duty well. Mountain people have their own tricks

Listening to Tang Yu's words, Bai Kaifeng's eyes brightened, and he felt relieved. But he knew that Tang Yu was so powerful. In terms of wisdom, apart from the magpie king, who can compete with Tang Yu?

At the same time, Jin Chenghu's room.

Jin Chenghu's face was furious. Looking at an old man wearing a medicine robe and a goatee, he pressed down his anger and asked in a hurry: "Purple medicine, how is my son?"

"The situation is not very good. The channels on my body were burned by the fire, and some of them were broken."

The goatee old man said slowly, "however, when I refine a mailuodan for him to take, he will recover in a short time, but the trace on his face, I'm afraid, can't get rid of it. The person who started the attack is really a cruel means. If there is no master Xuandan to refine the vein pill for Jinshi, it will take at least 10 years for Jinshi to recover! "
