The sun slowly climbed up from the east. Under the sunlight, the sea surface was sparkling and very beautiful.

Eight meters below the sea level, Huang Shuai was pressing his face against the periscope, staring at the transport fleet that was slowly passing in front of the submarine.

"Bow angle: 90 degrees."

"Speed: 6 knots."

"Distance: 3400 meters."

"Torpedo depth: 3.5 meters."

"Set torpedo speed: 42 knots."

"Torpedo tube No. 1 on the bow."

"emission!"

puff!

The Squid's No. 1 launch tube spits out a heavy torpedo weighing 1.2 tons.

When the torpedo leaves the launch tube, the air valve and fuel valve are opened, and under pressure, they are sprayed together into a special mixing vessel, where the fuel is mixed with air and then injected into the four-cylinder engine.

Under the strong power provided by the engine, the two propellers at the tail of the torpedo rotated rapidly in opposite directions, and the torpedo quickly shot out towards the troop transport ship like an arrow off the string.

Huang Shuai did not order to dive, but just stared.

This is a troop transport ship of approximately 3,000 tons. It is a commercial ship capable of both passenger and cargo use. It is currently severely overloaded and carries two brigades of nearly 3,000 people.

Don't think it's outrageous, every country has done this kind of thing. After all, it's not a long-distance voyage, but a temporary dock across the Tsushima Strait from Japan to North Korea, which is very close.

When Japan's transportation capacity and resources are seriously insufficient and there are no external threats, overloading is overloading.

After all, sending two brigades aboard at one time is equivalent to saving the transportation capacity of a ship. Even in the eyes of army veterans, this is a good deal.

But the ship is not big after all. The two brigades filled almost all the places on the ship where people can stand. The outside was fine. The soldiers inside the cabin not only had to endure the harsh environment, but also had to hold back and not be able to go to the toilet because there was no room.

superior.

"what is that?"

"Is it a fish?"

"Are you fainting from hunger? Those are bubbles, but why are the bubbles arranged in a line?"

The soldiers on the ship discovered the torpedo tracks, but did not realize the seriousness of the matter.

Not to mention Japan at this time, even an ordinary British or American may not realize what is going on.

Not to mention the Japanese who are quite ignorant, poor and ill-informed.

After all, although torpedoes have been around for many years, they are still a high-tech weapon that most people have only heard of but never seen.

Torpedoes really became famous. After Germany started unrestricted submarine warfare, torpedo attacks became famous with U-boats.

"It's coming towards us."

"It can't be a sea monster, right?"

"so fast."

"Go and call the captain!"

Boom!

The torpedo hit the middle of the transport ship, causing a huge explosion at a position 3.5 meters underwater in the middle of the transport ship.

The energy generated by the equivalent of more than 300 kilograms of TNT was completely released within a few tenths of a second. The huge energy lifted the transport ship up, and then slammed it into the water.

The keel of the transport ship could not withstand such a large movement and broke directly. After losing its support, the severely overloaded transport ship began to tear apart from the middle part.

In Huang Shuai's eyes, the explosion stirred up a huge water column dozens of meters high. The transport ship jumped twice on the water along with the water column. Then, the transport ship began to break.

The soldiers on the deck of the transport ship were thrown into the water like dumplings, and soldiers kept running out from inside the ship.

"The bow angle is 70 degrees to starboard, the other parameters remain unchanged, and the No. 2 torpedo tube is fired!" Huang Shuai took advantage of the victory and pursued the target, aiming at the ship behind the transport ship.

puff!

Another torpedo flew out, leaving a white trail on the water.

Huang Shuai clearly saw that his target ship was turning, but the ship's draft was too deep and the turning speed was very slow.

This troop transport ship is much larger than the previous one, with a displacement of more than 5,000 tons. It is still a passenger and cargo ship. Its name is written in Chinese characters, called Feiyuwan.

On top were soldiers from a regiment, as well as the command structure of a brigade, headed by an army major general who had just been transferred from the reserves and promoted.

Huang Shuai looked through the periscope and saw panicked sailors, army soldiers who jumped off the ship in fear, and an officer standing on the deck wearing a dark Japanese army uniform.

Boom!

The fate of Flying Fish Ball was not better than that of the previous transport ship just because of its larger tonnage. The hull was lifted up and then smashed down.

However, because it hit the front of the hull, the stress did not break the ship. The hull was only slowly capsized instead of breaking into two sections.

The previous transport ship had been torn into two pieces under the influence of stress and was sinking quickly.

Those soldiers who failed to escape could only sink with the hull of the ship. Those who escaped were not safe. A vortex would be formed when the hull sank. If they were sucked in, they would still be dead.

Boom boom boom...

The old cruiser escorting it opened fire, its boilers were burning brightly, and it quickly approached the direction of the Squid.

But Huang Shuai was not worried at all, because they did not feel the shock of the explosion, which proved that the artillery hit was very far, which meant that they were not discovered.

"Reload the torpedo cabin, dive to 25 meters, turn left 70 degrees, and move forward at full speed." Huang Shuai put away the periscope.

"Captain, the torpedoes in the bow torpedo room are exhausted, and there are only two torpedoes left in the stern torpedo room." the first mate reminded.

The sneak attack on the combined fleet and the transport fleet had already used up the four torpedoes on the bow of the Squid.

After all, it's not a combat submarine, and the torpedoes are just for precaution.

"Then just go forward and run in front of them." Huang Shuai thought for a while, moving here and there was not good and dangerous.

Half an hour later, Huang Shuai ordered to float to the height of the periscope again.

"They are following up, and they are very scattered this time." The Squid successfully moved around to the front of the transport fleet, and is now directly ahead.

"Do you want to attack now?" The first mate looked at the chart and frowned slightly.

"The Japanese are very scattered. Our position is not very good. We only have two torpedoes, so we can't waste them." Huang Shuai observed the targets worth attacking.

Torpedoes are not cheap. Each one costs tens of thousands to build. They are also consumables. A small broken Japanese ship may not necessarily be as valuable as a torpedo.

Huang Shuai first skipped those small and old ships, unless they were densely packed with sailors, which had enough added value.

"If we go any further, we will enter shallow water, which will be very dangerous," the first mate said.

The Squid was only twenty kilometers away from the land when it was lost. Later, after discovering the Japanese transport fleet, it moved a few kilometers south. This is how the vertical position came about.

But now it has changed its course and is approaching the land. The closer it is to the land, the shallower the water and the more various reefs there are, making it extremely dangerous.

What is an island? If there is no water, it is a mountain. When water comes, it becomes a reef when it is submerged. If it is not submerged, it is an island. If it is not submerged and there is still a road access, it is a peninsula.

There are many islands nearby, which means there are also many reefs.

"Is this so?" Huang Shuai looked at the map and saw that we were only a dozen kilometers away from the shore.

"Turn five degrees to the left and maintain the speed of four knots." Huang Shuai took a look and found the largest boat.

It's about 130 to 40 meters long and about 30 meters wide. It's the shape of a cruise ship, but it's not very close.

"The torpedo is set at a speed of 42 knots and a depth of five meters."

"Fill the stern torpedo room with water and stop the engine." After silently estimating the distance, Huang Shuai chose to stop and wait.

The Japanese were already alert. This position was not ideal, and there were not enough torpedoes to carry out a fan attack, so they could only attack at close range.

After waiting for about five minutes, no one spoke on the Squid for five whole minutes, and one could even hear each other breathing.

"The distance is two thousand four hundred, the speed is ten knots, the attack angle is normal, and the torpedoes are launched from the stern of the ship!" Huang Shuai thought that the Japanese must not be able to run away from this distance before giving the order.

puff!

The torpedo tube on the Squid's stern made a pop sound, like a fart, and released the torpedo.

Boom!

Suddenly a shell exploded not far from the periscope, and water even splashed onto the periscope.

"Retract the periscope, dive slowly to fifteen meters, turn 90 degrees to the left, and sail quickly."

I didn't feel much vibration. After all, it exploded on the water surface, and the caliber of the cannon was not large. It should be a rapid-fire cannon with a caliber of about 150 mm. It did not pose much of a threat to the Squid, which was about eight meters underwater.

Buzz…

rumble……

As soon as the submarine started moving, Huang Shuai heard a dull explosion, which proved that the torpedo had hit the target and exploded.

I looked at my watch, it was less than two minutes.

The distance between the two sides is 2,400 meters, the torpedo speed is 42 knots, the ship's speed is about 10 knots, the relative closing speed is 52 knots, and it only takes 90 seconds to cross 2,400 meters.
