Zhou Yunhai stared at the distance between the two ships on the big screen in front of him, 1.5 km, 1.2 km, 1 km! "Tiger Shark unlocked! Put! Turn right 30 degrees! Zhou Yunhai ordered loudly, and the crew, who were already in an extremely nervous state, immediately started the relevant operations, and the 331 ship made a beautiful throwing action at the bottom of the sea, and suddenly turned around at a distance of a few hundred meters from the Canglong-class submarine!

"Chinese are really cowards" Koizumi swallowed a mouthful of spit secretly, just now the opponent showed a decisive posture that made Koizumi's vest break out in a cold sweat, but Koizumi knows that his upper peak Haneda is also a madman, he will never take the initiative to avoid in this situation, in this case, what Koizumi can do is to stare at the opponent's position change, ready to adjust the depth of the submarine at any time, to ensure that in the final stage can float, avoid head-on collision, aim at the weak point of the opponent's bridge.

But at the last moment, the Chinese retreated, much to Koizumi's great relief.

"Turn left 30 degrees!" Haneda Chong did not give him nonsense, but while staring at the turn of the Chinese submarine, he ordered that he would catch up and damage or even sink this Chinese submarine!

"Haneda, what is this!" After Koizumi carried out the order, he was surprised to find that after the Chinese submarine flashed away, there was a small black dot behind it appeared on the sonar screen, and from the noise analysis results displayed by the side sonar, it should be a miniature submarine! And the ship's anti-torpedo system did not respond, which also means that it is not a torpedo.

But how could such a small submarine follow behind the Chinese?

In the face of this sudden change, Haneda Chong, who originally had a cold face, couldn't help but change his complexion, at this moment, the Canglong submarine had just performed a steering, and the speed had suddenly decreased a lot, and it was impossible to do a steering maneuver again immediately, "Urgently float!" Haneda Chong was anxious and ordered that at this moment, the miniature submarine was only more than 200 meters away from the Canglong submarine, and Haneda Chong could dodge if he wanted to.

"Puff" There was a low and huge muffled sound, which made everyone on the 331 ship a few hundred meters away feel a strong tremor, "Success!" As Li Tiancheng, who had been nervously operating the tiger shark remotely, cheered, the crew in the command cabin immediately boiled, "Attention units!" Anti-torpedo systems ready! Beware of devil dogs jumping off the wall! Full speed away! Zhou Yunhai ordered loudly, although his heart was also very excited at the moment, but in the current situation, he must strengthen his vigilance to prevent the devil from attacking madly in a dying situation.

The 331 ship drove the S-1 nuclear reactor to the maximum capacity, and the submarine, which had been slowed down a little due to the steering, immediately began to accelerate away, "Lao Li, now play back the video from the last period to see if you can confirm the part of the impact?" Seeing that the submarine was getting farther and farther away from the devil, Zhou Yunhai asked.

"It should be near the bridge." Li Tiancheng said confidently as he operated the touch screen to recall the video data before the impact, "I have seen the bridge of the devil submarine very clearly in the final stage. ”

Soon Li Tiancheng called up the video data uploaded back by the tiger shark, and fast-forward to the final stage, and he could clearly see that the tiger shark was facing the junction between the bridge and the hull of the devil submarine. "Hehe, this is enough for the devil to drink a pot!" Zhou Yunhai looked at this video clip, and then laughed happily. This position is relatively vulnerable on the submarine, and the tiger shark of several tens of tons directly hit it at a relative speed of more than 30 knots, even if it did not directly knock off the bridge of the devil.

At this moment, the command system of the devil submarine must have failed.

Zhou Yunhai thought while looking at the detection information from the sonar in the direction of the side direction, the devil's Canglong submarine has now lost its speed, and only inertia is left to move forward.

"Report to the detachment, the Tiger Shark has inflicted heavy damage on the opponent, and the 331 ship requests to return!" Seeing this result, Zhou Yunhai relieved himself and began to report the results to his superiors.

The next day, the spokesman of the Ministry of Foreign Affairs announced with deep sorrow that a Chinese scientific research submersible violently collided with a submarine of unknown nationality while carrying out a scientific research mission in the Chiwei waters, and that the collision incident resulted in the complete destruction of the submersible and the loss of a large number of scientific research materials, causing great losses to the Chinese scientific expedition.

The bridge was seriously damaged, causing the personnel of the command center of the devil Canglong submarine to die instantly, and the Canglong submarine, which lost its command, soon ran aground and sank in the Chiwei Sea. However, due to the suddenness of the incident, the devil sea did not understand what happened at that time, and the submarine sent out for rescue could not open the exit of the severely deformed Canglong-class submarine, so they had to tow the submarine to a suitable depth to allow the personnel in the submarine to escape from the torpedo launcher.

However, with the death of all the personnel in the command center, there are only some remnants of sonar records that can be inferred, and the devil intelligence analysts only learned that this submarine had previously conducted a confrontational demonstration with a Chinese submarine, and then there was a collision with a Chinese "scientific research" submersible.

Unable to find any evidence of an attack by the Chinese side, this mute man had no choice but to knock out his teeth and swallow blood.

Seeing that the navy's method was working, Mr. Liu, who had a great deal of bad breath, ordered this tactic to be widely used in the waters of the East China Sea, striving to turn the bottom of the East China Sea into a devil's sea area that terrified the Japanese invaders.

In the next month or so, Zhou Yunhai's detachment succeeded in this way, and successively used the tiger shark to hit several different types of Japanese submarines, although the luck was not as good as the first time, and directly hit the vital point of the Japanese submarine and sank, but some of them had a rear-end collision with the butt of the Japanese submarine, seriously damaging its tail rudder and power drive, and some were head-on and destroyed the bow of the Japanese submarine, and there was also an opening in the center of the ship...... And so on and so forth.

It will take at least several months to repair these Japanese submarines, which have been badly damaged in various "accidents", after they have worked hard to get them back. Such a serious loss forced the Japanese side to suspend its activities in the East China Sea and concentrate on studying and cracking this new tactic of the Chinese side.

In terms of the study of submarine miniature submersibles, the Japanese even had a better advantage in this regard, so after studying in detail the situation of several wrecked submarines, the Japanese quickly figured out the main points of the Chinese side's tactics, and they decided to use the same tactics to confront the Chinese side.

However, with the Zhou Yunhai detachment, which has been extremely proficient in tactical exercises, the Japanese are just doing this to imitate the east, and reduce the losses a little, in this undeclared submarine dark war, every month there are Japanese submarines are hit and damaged, and the optimized and improved Tiger Shark has become the common name of the navy for this special submarine, with stronger speed and better shape, and the front of the submarine is made of ultra-high-strength special steel developed by Dushi Heavy Industries, which makes it more sharp in the impact.

As a result, the Chinese side gained the upper hand in this undersea battle, causing heavy losses to the Japanese submarines.
