Azur Lane: I took the graduation port area through time

"What is that light beam?"

"Oh my god, what is that in the sky! How can there be such a terrifying blue vortex!"

The strange phenomenon caused by this shocking blue light beam made everyone in Yalang City look up in shock at the night sky that was dyed blue.

"Lin Lan, what is this?"

Luo Tao and his three destroyer girls also came from the street at this time.

Seeing the huge beam of light in front of him, Luo Tao looked at Lin Lan in shock and asked.

"Now that you are the commander with the highest authority in this city, go to the port area immediately and sound the highest level evacuation alert in the city!"

When Lin Lan heard Luo Tao's voice, he immediately turned around and spoke to him in a deep voice.

He knew very well that the arrival of the high-level siren would definitely bring a large number of siren fleets.

"Ming Muhan, the general agent of Tomahawk Military Industry in Yalang City, has defected to the Siren, and the Siren's large fleet is about to attack!"

Hearing Lin Lan's words, Luo Tao couldn't believe his ears.

"Where is the supreme commander, Li Banan?"

"That guy has been killed by Ming Muhan, you should do as I say now!"

Lin Lan's words made Luo Tao tremble.

The amount of information contained in Lin Lan's words was too much for him.

But Luo Tao quickly cleared his mind, took a few deep breaths, and forced himself to calm down.

"I understand. I will go back to the port area now to sound the city-wide alarm and issue a call for help to other cities."

Luo Tao now firmly believed in Lin Lan's words. After thinking for a moment, he continued as if he had made some decision:

"Li Banan's ship girls in the port area, I also try my best to persuade them to obey my orders and help us fight against the sirens."

After saying that, Luo Tao nodded to Lin Lan and immediately rushed to the port area of ​​Yalang City with three destroyer girls.

Looking at the backs of Luo Tao and others, Lin Lan felt gratified that her classmates could make the most correct decision at the moment.

But he deeply understood that facing the high-level siren, it was impossible to withstand the warship girl with only those chess pieces.

At this time, Zeppelin and Brünnhilde, who had completely destroyed the Tomahawk Military Industrial Base, came from behind the building.

When Brunhilde just destroyed the Tomahawk military industrial base, she did not take action because there was no need for her to take action.

"Is it the beacon of a high-level siren?"

Qi Bolin, who walked to Lin Lan, looked up at the blue beam of light, suddenly stretched out his hand, and shook it hard.

"Crack!"

The light beam shattered instantly, but the blue vortex in the sky still existed in the sky, constantly rotating.

"Commander, it seems that this city has been targeted by a certain high-level siren."

Brünnhilde watched with a solemn expression as the beam of light was destroyed by Zeppelin, but the blue vortex in the sky still did not dissipate. She looked at Lin Lan and said in a serious tone.

After hearing Brünnhilde's words, Lin Lan looked in the direction of the ocean with complicated eyes.

At the same time, in the upper reaches of the river in Yalang City.

Under the surface of the river, dozens of black and yellow Siren mass-produced submarines slowly started from the mud under the river bed.

But in the mud and sand on the river bottom that was raised when the mass-produced siren submarine was activated, seven or eight white-haired humanoid siren girls with ponytails and goggles on their foreheads appeared.

With sinister smiles on their faces, they rode on shrimp-like black and yellow uniforms and sailed toward the river without making a single sound.

Siren Experimental Facility, Executor Series, Lurker Type I.

They are humanoid sirens in the submarine category. Whether it is the attack power of torpedoes or their own armor HP, they are far more powerful than mass-produced siren submarines.

The boats on the river were still moving forward slowly under the night, completely unaware that the threat from below the river was slowly approaching.

Whether it was a yacht or a cruise ship, all the radar equipment showed no sign of the Siren's arrival.

Just when the Lurker and Siren submarines were about to launch torpedoes against the living targets on the river, several objects with white metallic luster fell silently from the water above.

"Dong dong dong!"

A huge explosion erupted underwater, and the powerful impact destroyed several mass-produced submarines in an instant.

This is a weapon specifically designed to attack submarines, a depth charge.

The mass-produced and executor sirens are both cold and emotionless killing machines. When attacked, they immediately changed the target of their first attack.

A small iron-blooded silver-haired destroyer moved forward at full speed on the river, dragging out a white wave.

Z46.

The movement caused by the explosion of depth charges just now attracted the attention of all the ships on the river.

"Anyone who doesn't want to be sunk by a Siren submarine should leave here as quickly as possible. This river is blocked tonight."

As seven or eight black carrier-based aircraft flew across the river, the girl's voice echoed across the river.

Weser, a light-sailing girl with short red hair and fully equipped ship equipment, was at the edge of the river bank, controlling the carrier-based aircraft to continuously disperse the ships on the river.

"What's the trick? Let's not mention that there are no sirens on the radar. How could the sirens appear in the river?"

"That's it, is it true that the Minato area on the seaside of Alang City is vegetarian?"

After hearing what Weser said about the appearance of siren submarines, the personnel on some ships still did not believe that sirens would appear in the rivers here.

But as several ships suddenly erupted into violent flame explosions, all the people driving the ships immediately fled at full speed without saying a word.

"Leonie, how many siren submarines are there? Can they handle them?"

Weser asked loudly as he looked at Z46, which was moving rapidly on the river and using the Iron-blooded Shark suit to throw depth charges into the river.

"No problem, it's just a group of Type I Siren mass-producers and lurkers. I can deal with them."

The mouthless little loli Z46 answered in an indifferent tone.

She controlled the ship's uniform and flexibly drew beautiful curves on the river.

The torpedoes of the Siren submarine behind her could not catch up with her at all, and could only be destroyed by depth charges like kites.

"That's good."

Weser is naturally assured of the strength of Z46.

It was indeed the right choice for the commander to arrange for the two of them to come here in advance.

However, without them around, is there really no problem with the commander?

Weiser looked worriedly in the direction of Yalang City. In the sky above the city, the huge blue vortex of air flow made Weiser feel uneasy.

Zeppelin and Brynhildr alone are too weak to fight against the high-level sirens.

Sure enough, he should deal with the submarines here faster and go back to help the commander.

Weser drove the carrier-based aircraft to sink several siren submarines that surfaced, but she became increasingly anxious.

The anti-submarine efficiency of her and Z46 is too slow.

She is not equipped with an anti-submarine aircraft and cannot directly attack submarines still under the river surface.

But looking at the beacon of the high-level siren in the distance, Weiser couldn't wait to return to the commander immediately.

She really couldn't understand why Lin Lan asked her to protect these ordinary ships.

Commander, you should obviously put your own safety first!

Weiser became more and more anxious as he watched the Siren lurkers emerging from the water and controlling the carrier-based aircraft to continuously attack these annoying Siren submarines.

"Leonie, please return to the port area immediately and ask for help from Huten and the others. Leave this place to me first."

After destroying two more lurkers, Weiser finally decided to disobey Lin Lan's order and gave a loud order to Z46.

She couldn't just watch the commander in danger.

Z46 received her order without saying a word, but by sailing towards the port, it showed that her thoughts coincided with Weiser's.

The commander must not be put in danger and must return to Hong Kong immediately to request assistance.

At this moment, a noisy sound suddenly came from Weser's communicator.

"Hey Hey hey?"

"My dear fourth sister, can you hear me? Uh-huh~"

Weiser's heart suddenly trembled when he heard the familiar slovenly tone of voice in the communicator.
