Although no trace of the submarine was found, and no one saw the trajectory of the torpedo, Pifanu, the commander of the Royal Navy's escort fleet in Monia, quickly determined that the sunken super dreadnought battleship Narcissus should have been attacked by a submarine.

Commander Pifanu immediately ordered all the warships of the Monia Royal Navy equipped with depth charges to immediately drop depth charges on all suspicious places, but only fifteen light cruisers of the remaining more than 160 warships of the entire Monia Royal Navy were equipped with depth charges, and the number of depth charges on each light cruiser was not much.

These fifteen light cruisers were not specially carried depth charges, but after the submarines of the Royal Navy of the Salad attacked the port of Newport City at night, the Royal Navy of Monia hastily developed a batch of improvised depth charges in order to guard against the Royal Navy of Salad, and equipped a group of light cruisers of the Royal Navy of Monia.

In the bridge of the Monia Imperial Royal Navy's super dreadnought battleship Banshee, Commander Pifanu said to Harowe, the captain of the Banshee, with a gloomy face: "Why are only fifteen light cruisers equipped with depth charges among our more than one hundred and sixty warships, this is simply ridiculous, how can we deal with enemy submarines?" ”

When Harowe, the captain of the Banshee, heard this, he couldn't help but complain in his heart, you Pifanu are the commander of the escort fleet, and the information of the entire escort fleet was all handed over to you before departure, and only the responsibility for the fifteen light cruisers to be equipped with depth charges should be completely taken care of by you, the commander, and you are now asking me what I mean!

Of course, it was impossible for Harowe, the captain of the Banshee, to say what was in his heart, he groaned for a while and said: "Commander, according to the information that each country has learned, the navies of the Tang Empire and the Purple Moon Empire are not equipped with submarines, so we have not equipped each warship with depth charges. ”

Commander Pifanu put his hands on his head and said, "So what should we do now?" It is clear that the Narcissus must have been torpedoed and sunk by a submarine, and so many of our warships carry only a small number of depth charges that can be used against submarines. ”

Haroway, the captain of the Banshee, then suggested, "Commander, I think we should first send a telegram to His Excellency Yuric, the commander of the Ryerland Naval Escort Fleet, to inquire about the depth charges that the Rareland Naval Escort Fleet is equipped with. ”

Commander Pifanu lowered his hands, nodded and said, "Then hurry up and ask the Ruierland Navy, are there many depth charges carried this time?" I didn't expect that the navy of the Tang Empire was even equipped with submarines, and sent a telegram to the Admiralty to tell the Admiralty the news that the Narcissus had been attacked by a submarine and sank, and asked the Admiralty if it had any suggestions? ”

Soon Yurik, the commander of the Ruierland Navy escort fleet, sent a relatively bad news to Pifanu, because the Ruierland Navy also did not know that the navy of the Tang Empire had submarines, so this time the entire Ruierland Navy escort fleet only had a small number of light cruisers on top of them, equipped with a small number of depth charges.

After reading the telegram sent by Ryerlan Naval Commander Yuric, Pifanu sighed and said to Harowe, the captain of the Banshee: "We are in trouble, now that the escort fleets of our two countries combined, there are not many depth charges, and we don't know how many submarines the navy of the Tang Empire has, it seems that it will be very difficult for the escort fleets of our two countries to get close to the coastline of the Liuyun Empire." ”

As soon as Pifanu's words fell, suddenly there were several violent explosions in the distance, and the commander Pifanu hurriedly looked out of the observation window of the bridge, and then Pifanu's face became even more ugly, and the Royal Navy's Loyalty-class battlecruiser was also attacked by a submarine.

However, what Pifanu didn't know was that the submarine that attacked the battlecruiser Loyalty was not the U18, but the U25, which had hurried from nearby after receiving the telegram from the U18.

The U25 launched four 533-mm torpedoes at the Royal Navy Loyalty of the Monia Royal Navy, a battle cruiser with a full load displacement of up to 26,900 tons, and quickly began to dive without even having time to see the results.

As a result, three of the four 533-mm torpedoes hit the battlecruiser Loyalty, which not only opened three huge openings for the Loyalty, but also caused explosions in three of the three boilers of the Loyalty, high-pressure steam leaks in several steam pipes, and caused fires.

Immediately after the attack on the battlecruiser Loyalty, three light cruisers of the Monia Royal Navy, armed with depth charges, dropped more than 30 depth charges in the vicinity of the battlecruiser Loyalty, but they did not pose any threat to the U25, which had already dived more than 100 meters below the surface.

These light cruisers of the Monia Royal Navy are equipped with depth charges of only 20 kilograms, and they can only explode at a depth of more than 60 meters, and they cannot threaten the U25, which has already dived more than 100 meters.

Although the battlecruiser Loyalty was not sunk by three 533-mm torpedoes, the power system of the battlecruiser Loyalty was very badly damaged, and after the damage control personnel on the Loyalty, the speed of the battlecruiser Loyalty was less than 3 knots.

In addition, in order to avoid the continued attack of the submarine of the Tang Empire Navy, the escort fleets of Monia and Ruierlan accelerated the evacuation of the sea area that was attacked, and they turned around directly, and did not move in the direction of the coastline of the Liuyun Empire.

It turned out that the Admiralty of the Monia Empire learned that the escort fleets of the two countries were attacked by the submarines of the Tang Empire Navy and that a super dreadnought battleship had been sunk, so they immediately consulted the emperor of the Monia Empire, and then ordered the Monia Royal Navy escort fleet to return the same way and not have to go to the Liuyun Empire again.

Yuric, the commander of the Royal Navy's escort fleet in Rieland, soon received the same order, and asked his escort fleet to return the same way to avoid suffering greater losses.

However, when the escort fleets of the two countries withdrew, one of the battlecruisers of the Royal Navy of Rareland, the Canyon, was also torpedoed, and this time the attack on the battlecruiser Canyon was the U18, which had sunk a super dreadnought battleship.

After the U18 submarine sank the Super Dreadnought Battleship of the Royal Monia Navy Narcissus, although the captain Xu Zhenjie was ready to risk attacking again, Xu Zhenjie did not immediately let the U18 float, but let the U18 continue to dive to a depth close to one hundred and thirty meters below the sea surface, and then commanded the U18 to sneak in the water for almost an hour, Xu Zhenjie ordered the U18 to float to a position six meters above the sea surface and raised the periscope. And six meters is already the maximum distance that the U18 periscope can rise.

At this time, Xu Zhenjie found that less than 1,500 meters away from the U18, there happened to be a huge battleship, and Xu Zhenjie recognized this battleship at a glance according to the memory in his mind, which should be one of the four Canyon-class battlecruisers of the Ruierland Navy.

Using the intelligence system of the original Cangyu Empire and the intelligence system of the Purple Moon Empire, the Royal Navy of the Tang Empire and the Royal Navy of the Purple Moon Empire collected the graphics of most of the warships of the world's major naval powers, so that the officers and soldiers of the two navies could identify them when they met, and even obtained the data of the warships of many countries.

The data of the Canyon-class battle cruiser of the Ruierland Navy suddenly appeared in Xu Zhenjie's mind, with a standard displacement of 25,500 tons, a full load displacement of 26,240 tons, a maximum speed of 25 knots, and four twin 45 times caliber 330 mm main guns.

In the face of the sudden appearance of the feast, Xu Zhenjie was polite, and directly ordered to launch four 533 mm torpedoes at the battle cruiser of the Ruierland Navy, and then Xu Zhenjie did not even wait for whether the four torpedoes hit the target, so he quickly ordered the U18 to dive quickly.

In the end, three of the four 533mm torpedoes launched by the U18 hit the lead ship of the Royal Navy Canyon-class battlecruiser in Rareland, although the Canyon was not sunk, but it was also seriously wounded, entering more than 2,000 tons of seawater, and the speed was even less than 4 knots.

The commander of the Royal Navy escort fleet in Rieerland, Yuric, then also sent a large armored cruiser to tow the battlecruiser Canyon.

In order to get rid of the threat of submarines of the Tang Imperial Navy as soon as possible, the commanders of the escort fleets of the two countries discussed by telegram and decided that the two navies of the two countries would leave two light cruisers and two destroyers to protect the two seriously injured battle cruisers, and the main forces of the escort fleets of the two countries would withdraw first.

Because the underwater speed of the VIIC submarine of the Royal Navy of the Tang Empire was less than 8 knots, the main forces of the escort fleets of the two countries quickly evacuated safely, but what the commanders of the escort fleets of the two countries did not expect was that on the morning of the next day, the two seriously injured battle cruisers and the two large armored cruisers dragging them, as well as the four light cruisers and four destroyers protecting them, were picked up by the eight Lion-class battlecruisers of the Third Fleet of the Royal Navy of the Tang Empire.

The U18 and U25 submarines were ready to take the risk of attacking again, but when they surfaced enough to raise their periscopes, they found that the huge fleets of the Monia Navy and the Rillland Navy had withdrawn the same way, and according to the speed of their two submarines under water, they could not catch up with the navies of these two countries, and even the two battle cruisers that were wounded in the back.

If the two submarines had ventured to the surface, they would have been able to reach a maximum speed of 17.7 knots, in which case they would have been able to catch up with the two battlecruisers that were wounded behind.

However, after the two submarines seriously damaged two battle cruisers of the Monia Navy and the Ruierland Navy and broke away from the main forces of the two navies, they reported to the Royal Navy Headquarters of the Tang Empire, and the Royal Navy Headquarters of the Tang Empire issued an order to the U18 and U25 submarines to stop the pursuit.

Then the headquarters of the Royal Navy of the Tang Empire forwarded the telegram sent by the two submarines to the Third Fleet of the Royal Navy of the Tang Empire, which was already cruising in the waters near the Liuyun Empire.

After receiving the telegram, the Third Fleet sent eight Lion-class battlecruisers over to see if they could capture the two seriously injured battlecruisers of the Monia Navy and the Ruierland Navy.

When eight battle cruisers of the Royal Navy of the Tang Empire appeared in the distance, two large armored cruisers, four light cruisers, and four destroyers of the Monia Navy and the Ruierlan Navy quickly accelerated and fled.

The mortally wounded Royal Navy battlecruiser Monia Loyalty, and the Royal Navy Canyon Battlecruiser Rareland raised the white flag before the eight Lion-class battlecruisers could get closer.

After the officers and soldiers of the Royal Navy of the Tang Empire took control of the two wounded battle cruisers, Su Yi, who was far away in Chang'an City, the capital of the Tang Empire, immediately received a prompt from the system, congratulating him on capturing two enemy battle cruisers and rewarding Su Yi with two British Lion-class battle cruisers.
