The Tongyu was blown and covered in bruises and suffered severe internal damage.

However, the excellent military technology of the Chinese Empire was reflected at this moment, preventing the Tongyu No. 1 from being completely sunk.

When Kim Sung-wo and his men were in despair, the Tongyu submarine suddenly hit a ridge, allowing them to see new hope for survival.

"There is actually a ridge here!"

"It's really God won't kill me!"

"Switch the engine off immediately and make no sound!"

The ridge is a mountain in the sea, which is submerged by the sea, but some mountains will form ridges in the ocean, similar to reefs in rivers and lakes.

In the Central Pacific region, there are tens of thousands of islands and reefs of various types, and these islands and reefs are actually formed by the sea level exposed by the sea mountain under the sea.

Mountains are high and low, and those below sea level become ridges.

The Tongyu dives to a depth of 200 meters, which is already the maximum depth. If you dive, it is not that safe.

This place is close to the Marshall Islands and the Mariana Trench. Once a problem occurs, the submarine sinks to the bottom of the sea and will be directly pressed into a cake by water pressure.

At this time, the Tongyu number actually hit the ridge, which was not marked on the chart, and became Jin Chengwu's life-saving straw.

He parked the Copperfish on this unknown ridge, turned off the engine, and forbidden all noises. In this way, when the active sonar of the Pacific Fleet swept over, it would be reflected by the ridge, and the passive sonar could not hear the signal and noise of the Copperfish.

As long as you hold on until night, you can escape from the sky.

On the sea, the anti-submarine formations of the Imperial Chinese Navy suddenly stopped because their sonar system could not detect the location of the Tongyu.

The news came back to the Thunder battleship, and Li Weiguo, Li Weijun, Chen Shen and others who were in the meeting to discuss were all stunned.

"Has it sunk the Tongyu?" Li Weijun asked impatiently.

The communications officer shook his head with a wry smile and replied truthfully: "The anti-submarine formation believes that they have severely damaged the Tongyu, but is not sure whether it has sunk. However, the Tongyu suddenly lost all signals. The anti-submarine formation is further confirming whether it has sunk the Tongyu!"

Li Weijun suddenly turned black and said angrily: "Tell them that if they did not sink the Tongyu number, they would go home and take their children. The Imperial Navy would not need to raise a bunch of waste!"

The communications officer conveyed Li Weijun's orders truthfully, and the commanders of the anti-submarine fleet ships there were also extremely ashamed, pushing one level and increasing efforts to search for the Tongyu.

Here, Li Weiguo also received the news in the Office of Commander Thor.

Li Weijun explained: "Your Majesty, don't worry, the Tongyu No. 1 will definitely not escape!"

Chen Shen added: "Anti-submarine sonar detected many ridges nearby. The Tongyu submarine may temporarily stop and land on the ridge to avoid sonar detection. However, as long as our anti-submarine warships are squatting nearby, they will have to come out when the air on the Tongyu submarine is exhausted."

Li Weijun frowned and said, "It's almost dark, they are afraid they will take advantage of the night!"

Chen Shen said: "I remember that the Pacific Fleet practiced nighttime anti-submarine operations, so there should be no problem!"

Li Weijun immediately glared at Chen Shen. Since Li Weiguo was present, he had to bite the bullet and said, "Of course! It was the night anti-submarine subject I caught with myself. I thought that as long as the Tongyu number came out, it would definitely not be able to escape!"

At this time, Li Weiguodao: "I believe you will handle this matter well! I will not go to Guam and immediately return to Xiaweiyi. At the same time, I telegraphed the cabinet to hold an emergency meeting to convey what I said just now to them and prepare them!"

Li Weijun and Chen Shen immediately received the order.

Under the night, hundreds of warships from the Pacific Fleet were densely distributed within a radius of 500 nautical miles, with bright lights, and the sonar system was still sweeping around the nearby waters over and over again to prevent the Tongyu from escaping.

Under the sea, the Tongyu number was extremely cold. Jin Chengwu and several of his men gathered together, shivering while discussing in a low voice.

"It's already midnight, when can we escape?"

"Wait! The sonar detection has not stopped yet, and they are still waiting for the rabbit. We will die when we go out!"

Jin Chengwu calmly judged that he was an excellent submarine commander, but unfortunately he was not the same as the Chinese Empire.

The sonar system swept over and over again. Every time it hit the submarine guardrail, several people trembled all over, and their nervous faces were pale.

"It seems they've gone far!"

The sonar scanning frequency is getting lower and lower, and the intensity is getting weaker and weaker. It seems that the anti-submarine destroyers on the sea have gone far away.

"Did they give up searching for us?"

"Impossible! They will never let us go! This must be a trap! They must be still on it!"

Jin Chengwu snorted coldly, this trick could not be hidden from him, so he decided to wait.

Sure enough, half an hour later, sonar suddenly came over in intensive calls.

The few people were so scared that they sat on the ground. As expected, Jin Chengwu guessed that the Chinese Empire Navy above did not set up a trap immediately.

Another hour later, the sonar scanning frequency became weaker again.

"They are really leaving this time!"

"Our air is almost exhausted, and I feel troubled in breathing!"

"You're psychological, so scared!"

Jin Chengwu snorted coldly: "The theoretical air reserves of our Tongyu submarine can last 72 hours, but in fact, they will almost be exhausted. We must last 24 hours before they will give up searching for us!"

One of the men said in horror: "Then aren't we all suffocated to death?"

Jin Chengwu said, "Don't worry, you can't die! Don't forget that we only have five people now, but there are dozens of people. The extra air is our final hope for breaking through."

The few subordinates calmed down and looked at Jin Chengwu admiringly. Unexpectedly, their boss even planned to plot against this.

"I planned to escape in the dark at night, but the other party would think of this, so we must not escape at night. We just lurked like this. After 24 hours, they would believe that we were suffocated to death or had already escaped. When they relaxed their vigilance, we would succeed."

Jin Chengwu said proudly, there is no time to make him prouder than this.

However, at this moment, a sneer came from behind him.

"Kim Sung-woo, you traitors of the empire, you can't escape!"

"Who?"

Jin Chengwu looked back and was immediately scared to death.

I saw a bloody man standing at the door of the second cabin, covering his left chest with his hands, looking at them coldly, very terrifying and gloomy.

"Chen Dachun? You are not dead?"

Jin Chengwu quickly recognized the bloody man, Chen Dachun, the captain of the Tongyu submarine.

It turned out that Chen Dachun and others were caught off guard and were attacked and killed by Kim Sung-wo and his men.

Chen Dachun was shot in his left chest and heart, and blood splattered on the spot. Everyone thought he was dead.

However, Chen Dachun did not die because his heart grew more to the right than ordinary people, avoiding the deadly bullets.

However, Chen Dachun's lungs were penetrated, and blood blocked the trachea, causing him to suffocate and faint. Jin Chengwu and his men thought Chen Dachun was dead, so they threw the bodies of him and other submarine officers and soldiers into the rest cabin.

When throwing the corpse, the blood in the trachea happened to flow backwards, and the impact made Chen Dachun come back to life.

Because Jin Chengwu had too few people and time was tight, his subordinates did not check carefully, so Chen Dachun escaped the disaster again.

However, Chen Dachun was shot in the chest and lost too much blood. Although he woke up, he had no energy and was afraid of being discovered, so he could only hide it first.

It was not until the Tongyu was attacked and lurked secretly on the ridge that Jin Chengwu's men all went to the command cabin, which gave Chen Dachun the opportunity.

Chen Dachun first quietly went to the infirmary, bandaged himself briefly, and then gave him a shot of the paradise. Only then did he gain some energy and staggered to the command room.

In fact, Chen Dachun wanted to get the backup weapon and killed Jin Chengwu and his men, but unfortunately the weapon was on the other side of the command room, and Chen Dachun couldn't get through.

"Chen Dachun, what can you do if you are alive? You don't have a gun! How can you beat the five of us?"

Jin Chengwu snorted coldly. His attitude towards Chen Dachun was very complicated. The two have been together for more than five years and still have feelings. If it were not forbidden, he would not have killed Chen Dachun.

At this moment, Jin Chengwu wanted to let Chen Dachun go, provided that Chen Dachun surrendered obediently.

"Haha! I can't beat you, but I can die with you!"

"You traitors from the empire, all go to die!"

Chen Dachun shouted violently, his eyes filled with anger, and he reached out to close the hatch door.

When Jin Chengwu saw it, he was shocked and said in horror: "No! Stop him quickly and don't let him lock the hatch door!"

However, it was too late. When Jin Chengwu and his friends rushed over, Chen Dachun had already closed the hatch door and pulled down the gantry gate at the same time.

The gantry gate, as the name suggests, is an emergency equipment above each cabin door of the submarine. When the submarine is attacked and water enters the cabin, the gantry gate is lowered to completely isolate the water inlet compartment. Once the gantry gate is dropped, it cannot be opened again.

This was originally used to protect submarine personnel, because submarines of the Imperial Chinese Navy often had accidents, and most of the shipwrecked personnel were drowned because they had no time to escape.

Therefore, the Navy Equipment Department developed a gantry gate. When water in one cabin of a submarine cannot be stopped, it will open the gantry gate and completely lock the cabin, thereby protecting other cabins and buying time for rescue personnel.

Chen Dachun pulled down the dragon gate to isolate Jin Chengwu and the other two in the front of the command cabin together.

In this way, Chen Dachun had enough time to do something in the back of the submarine.

Several subordinates tried to open the gantry gate, but in vain, and then looked at Jin Chengwu and waited for him to speak.

Jin Chengwu smiled bitterly and sat on the ground.

He had already guessed what Chen Dachun would do. After so many years of partnering, he really knew Chen Dachun too much.

"Head, what should I do?"

"If I guess correctly, Chen Dachun will definitely start the engine and make noise to the greatest extent, or he will directly open the Tonghai valve and sink the copper fish number!"

"Then he is different from his death? Isn't he afraid of death?"

Jin Chengwu smiled bitterly and said, "Of course he is not afraid of death! Soldiers who can serve on submarines will not be afraid of death!"
