The sailors aboard the Brave at this time did not know that the danger was approaching. The Brave actually had some sailors on patrol, but they were more concerned about the situation on the water, and from time to time they used the searchlights prepared on the warships and imported from the Chinese Empire to scan the surface of the water, and no one thought that the danger came from underwater.

"Torpedo tubes No. 1 and No. 2 are ready." Hess commanded in a low voice, and then he ordered, "Torpedo tube No. 3 loading." To be on the safe side, he attached the torpedo tubes in the stern of the boat to the torpedoes.

"No. 1, No. 2 launches." With Hess's order, two torpedoes slid out of the launch tubes.

In order to ensure the hit rate, the U21 submarine was only more than 100 meters away from the 'Brave', and it was easier to hit the target when it was close, but it was easy to be injured by mistake at such a close distance, so after the torpedo was fired, Hess immediately ordered the submarine to turn around and retreat into the distance.

There were two loud bangs, "boom" and "boom", and the distance of more than 100 meters passed in an instant, and the two torpedoes accurately hit the side of the "Brave", and the huge water wave made Hess's submarine shake for a while.

The ironclad's fragile waterline armor could not withstand the attack of the high-explosive torpedoes, and two large holes appeared at the waterline of the 'Brave', and then the influx of sea water flooded the boiler room, fortunately, it was docked, and the boiler did not catch fire, but the 'Brave''s unreasonable watertight compartment could not withstand such a fierce attack, and it immediately began to tilt and quickly sank to the berth.

The huge explosion alarmed the fleet, the alarm in the harbor was loud, and the fleet commander thought that the fleet of the Yaman Empire was coming, and all the warships were ordered to light fire and prepare to go to sea to meet the battle, and taking advantage of the chaos, Hess sent three cruisers to the bottom of the sea with three torpedoes.

Due to the close distance, the hit rate of the torpedoes was very high, and the continuous explosions caused chaos in the entire military port, and even the batteries began to fire indiscriminately at the vast night of the open sea.

"Captain, we still have a torpedo, let's go back after sinking one of his cruisers." The first mate has now admired Hess, and he has the courage to run into someone's military port to make a fuss, and he has succeeded.

Hess smiled and said: "Don't worry, let's leave the port slowly, and then fight when we have the opportunity, I will be of great use to the last torpedo." ”

The panicked warships in the harbor began to leave the port one after another, and the first was naturally a relatively fast cruiser, a 'Kokang' class cruiser, which slowly entered the narrow exit channel and sailed out of the port. Hess, who had been observing with a periscope, immediately spotted it: "It's now, torpedo tube No. 3 is launched." ”

At Hess's order, the last torpedo in the tail torpedo tube of the U21 submarine was also fired, and the huge torpedo slammed straight into the bow of the cruiser with the surging waves. "There's a torpedo." The sailors on the cruiser finally spotted the torpedo, but unfortunately the cruiser was in a narrow channel and there was no room for maneuver at all.

The torpedo slammed straight into the cruiser's bow, tearing a hole in its waterline, and the cruiser sank in the course at a speed visible to the naked eye. Hess laughed, "What do you think?" This cruiser sank on the exit channel, and it was possible to blockade the port of Liverpool for half a month, to say the least. ”

The first mate was pleasantly surprised: "Captain, you are really a god, you can think of such a bad trick." ”

Hess knocked him on the head and laughed and scolded, "Are you praising me or hurting me?" ”

The commander of the Saar Imperial Navy, Field Marshal Jericho, was called by the adjutant before he could get up, and when he heard that the Liverpool military port had been attacked, he immediately rushed to the naval staff. "How's it going?" Marshal Jericho asked aloud as soon as he entered the door.

"Marshal, the situation is very bad." "We have one ironclad and four cruisers sunk, one of which was sunk on the way out, and it sank in the fairway, and it is estimated that it will take at least ten days to clear the channel," said the chief of staff, Vice Admiral Spee. ”

Listening to Spee's report, Jericho gasped: "How is this possible, the fleet of the Yamans is still in the military port, what are they using to attack us." ”

"There has been news that a merchant ship has been sunk by an invisible enemy some time ago, and I think they should be using the same weapon, and this mysterious weapon is supposed to be sailing underwater, so we can't see it," said Vice Admiral Spee. ”

"Underwater? No way. Jericho said angrily: "The intelligence secrecy of the Yaman Empire cannot be so tight, if they were researching such weapons, we should have already gotten the news." ”

Lieutenant General Spee stroked his nose and eyes, and said, "But if this magical weapon is not made by the Yaman Empire......"

"You mean the Chinese Empire?" Jericho guessed.

In the last decade, the Chinese Empire and its predecessor, the Chinese Lord, have become a nightmare for the Sahr Navy, and his endless new weapons have not only dazzled the eyes, but also caused the vast fleet that the Saar Empire had invested heavily in quickly falling behind.

Eight years ago, when the Sahr Empire was building ironclad ships, the 'Lanting' class battleships of the Chinese Collar were born, making all the ironclad ships of the Saar Empire obsolete.

When the Saar Empire caught up and built battleships again, the appearance of the 'Chinese' class battleships once again made all the warships of the Saar Empire face the fate of being eliminated.

Coupled with the chariots, trucks, airships and airplanes made by the Chinese Consulate on the army, Jericho could not imagine what the brains of the scientists of the Chinese Empire were made of, and they could create such a new and practical number of weapons.

As long as new types of weapons appear in the entire world, all countries will naturally think of the Chinese Empire. Therefore, after Lieutenant General Spee's question, Jericho first thought that this weapon was very likely to be a new weapon made by the Chinese Empire.

"Order all military ports to start laying mines on the sea, and let the Ministry of Foreign Affairs protest with the Chinese Empire to see if this new weapon can be bought." Before figuring out the specific situation, Jericho had to use mines to defend, mines can be half-sunk into the water, and there is a certain effect in defending against underwater weapons, but Jericho didn't remember that mines were also invented by the Chinese Empire.

After the transmission of cable telegrams, the Saar Empire's embassy in the Chinese Empire received an order a few days later. The ambassador to China, Zhu Erdian, immediately made an appointment to meet with Chen Guilin, the vice minister of foreign affairs of the Chinese Empire and Wu Qiong's deputy.
