Azur Lane Mobile Front.

As he ran toward the hangar, Rob checked the files of his ships one by one.

Because global experience is always a scarce resource, and Rob always tries to use every bit he has, he really has no way to find more experience points to level up right now.

"Wait, there's also this!"

After searching for a while, Rob found the several large boxes in his inventory.

Rob, who lacked confidence in his own luck, hesitated when he saw these last few hopes before him.

"Yukikaze, come here!"

Then, a white figure flashed past his sight.

"Hmm? Commander, what's wrong, Nanoda?"

Yukikaze had also been observing Shigure's situation.

Although the two are always in a competitive relationship, this does not prevent them from being very good friends.

Otherwise, Yukikaze wouldn't have thought of Shigure immediately.

Shiyu is now in imminent danger, and Xuefeng's little face is also full of worry.

"Check these boxes."

"I understand, nanoda."

Looking at the few miniature boxes lying in Rob's hands, Xuefeng obediently didn't ask anything, but simply followed Rob's instructions and clicked on them.

"It's all global experience!"

Looking at the uniform global experience points popping up in the system, Rob knew that there were no problems now.

"System, redeem the Ferocious Bird MK-II!"

While speeding towards the hangar, Robo first redeemed the mecha in the system.

Meanwhile, Helena, with Shigure in tow, was rushing towards Agama at full speed.

"Please, you have to make it..."

...

In Ryugu Castle, the ferocious bird 00R, abandoned there, has begun to tremble violently, and its outer armor is showing more and more cracks.

The overflowing energy has begun to tear apart the surrounding weapons.

Finally, the tipping point has been reached.

A massive black aura burst forth from the body of the ferocious bird 008R.

The black sphere instantly enveloped the entire Dragon Palace City and the surrounding sea area.

A black sphere, even larger than Strynchus's "Black Hole Cannon," appeared on the sea surface.

In just a moment, the black sphere expanded to its maximum size.

The sea surface seemed to fall silent instantly.

There was no explosion, no sound of anything being torn apart; everything was so quiet.

Unlike Strynchus's black hole, this one came and went quickly.

In an instant, a piece of the ocean was completely scooped away.

The Dragon Palace City from before vanished without a trace, leaving not a single mark.

In an instant, the enormous black sphere collapsed into a single point and then vanished, as if it had never existed in this world.

As soon as the black sphere disappeared, the seawater immediately began to fill the hole.

On the sea surface, a rare whirlpool formed in an instant.

The Sakura Empire's mass-produced ships, which had not yet had time to evacuate, had just escaped the black hole but not this vortex, and were all dragged in.

The Sakura Empire fleet, which had already retreated to a greater distance, watched helplessly as its mass-produced ships were dragged into the abyss.

Although all the ships are still relatively intact, after this incident, the already difficult situation of the Sakura Empire will likely become even more challenging.

Immediately after, Helena arrived at the hangar with the unconscious Shigure.

The berserk Shigure lost consciousness the moment the black hole appeared. If no immediate countermeasures are taken, she will soon disappear from this world.

"here!"

Rob had been waiting for quite some time beside the brand-new MK-II Fierce Bird.

He took Shigure from Helena and placed her hand on the machine. Now, it was all up to luck.

Fortunately, Shigure's luck was just as good as she often said.

After a flash of light, the Fierce Bird-MKII disappeared.

"She should be alright now, take her to rest."

Seeing Shigure still lying on the ground, not yet awake, Luo Bo finally felt relieved.

As long as the organism can synchronize normally, it means there is no major problem.

After handing Shiyu over to Helena, Rob had other matters to attend to.

By now, the iron-blooded Prince Eugen should have arrived.

Just as Rob had suspected, Prince Eugen, who had been brought over by Columbia and the others, was currently vomiting violently in the bathroom.

She had already drunk quite a bit without realizing it, and after what Columbia just did, the whole ship is now seasick.

"This...is really...ugh~"

Before she could finish a single sentence, she started vomiting again.

Of course, Prince Eugen and the others who were brought over from Colombia were in relatively good condition.

The white dragon, who had been brought here by Cleveland in his high mobility form, was now completely unconscious and lay motionless on the ground.

Even so, she still clung tightly to her knife, and it was unclear what important meaning the knife held for her.

...

Just as Rob was preparing to give Prince Eugen and his entourage a proper "welcome," a head popped up on the sea.

Then, the ship's equipment, resembling an octopus, surfaced from underwater.

"Oh my, this is really... interesting."

The observer, whom we haven't seen in a long time, looked at the energy readings in the air and the vortex still spinning beneath his feet, a playful smile on his face.

Chapter 308: Sirens: Mr. Luo, your black hole cannon is pretty good, let me take a look?

Without the slightest hesitation, the observer immediately transmitted the data back from here.

Meanwhile, the sirens located in a certain sea area immediately received the data uploaded by the observers.

"This is..."

The tester looked at the data transmitted by the observer and immediately realized something.

Immediately, another batch of data was retrieved by her.

This data was collected from some recent mass-produced models.

"Similar to, a weapon of arbitration bodies?"

Starting a few days ago, testers discovered something unusual in the final uploaded data of a large number of mass-produced models.

On the Sakura Empire side, it seems that someone has started using weapons similar to artificial black holes.

Because this incident was so bizarre, the testers initially thought it was an error that occurred during data upload.

It's important to understand that even for the Sirens, the artificial black hole is merely a simulated black hole that has just been researched and completed.

However, the data just transmitted by the observer forced the tester to re-examine the data that he had previously considered incorrect.

"We need more specific data..."

After compiling and packaging the previous data and the data just sent by the observer, the tester immediately sent another experiment request to the observer.

If the ships are ahead of them, they don't mind learning from them.

"Hehe~ You're pretty quick, aren't you?"

The observer, who was playing with his own tentacles, smiled even more broadly after receiving the message from the test subject.

"Oh, I can play with new toys again. I'm really looking forward to it."

"However, it's better to leave such a difficult matter to an arbitration body..."

...

On the spot, Rob looked at Prince Eugen, whose face was somewhat pale, and his expression was complicated.

As an opposing faction, what he should do now is to lock up these three Ironblood faction ships and see if he can extract any useful information.

However, since Princess Eugen came to her herself, it means that she must have foreseen this situation.

Therefore, ordinary methods are probably useless for her.

Moreover, she must have prepared a contingency plan for her escape.

Since that's the case, Rob felt he should ask this iron-blooded heavy cruiser what exactly he wanted to do.

Perhaps the excitement from earlier hadn't worn off yet, because Prince Eugen would occasionally cover his mouth and make some rather unrefined noises.

Rob wasn't in a hurry. Instead, he gently stroked the unicorn's head, making the unicorn squint its eyes.

While Rob was taking his time, Prince Eugen was also carefully observing Rob's group.

The things Ironblood is about to do concern the safety of the entire world, but as an opposing faction, she can hardly guarantee that the other side will believe her.

After all, the Ironbloods are now using a style that clearly reflects Siren Technology.

"Commander of the Eastern Empire, we, the Ironbloods, would like to make a deal with you."

After a stalemate, Prince Eugen finally broke the deadlock.

"A deal? I'm not interested. I just helped you out purely out of humanitarian considerations. Don't think it's because I have a soft spot for you, Ironblood."

Unaware of the other party's intentions, Rob directly rejected Prince Eugen's proposal.

"Don't rush to refuse!"

Having probably recovered, Princess Eugen's familiar smile returned to her face.

"After all, this transaction uses sirens as the main ingredient."

Robb did not reply, but simply stared silently at Prince Eugen.

Knowing that his words had piqued Robb's interest, Prince Eugen's smile became even more confident.

"However, before we talk about the deal, I'd like to ask, how much do you know about the Sirens?"

As if to whet Robb's appetite, Prince Eugen abruptly changed the subject, making no mention of the details of the deal.

"I know a little about it, but not much."

That's the truth. No one in this world can confidently say that they have a deep understanding of the Sirens.

It's important to know that even now, there's no concrete explanation for where the Sirens came from.

"Then let me ask a simple question: where exactly are the real Sirens?"

Seeing that Robb had finally fallen into his "trap," Prince Eugen was now 80% confident that he could persuade him.

Prince Eugen's question really surprised Robert for a moment.

He knew that none of the sirens he had seen so far were genuine.

After all, the Purifier had already been sunk several times by his daughter.

However, this not-so-bright siren still has plenty of eyewitness reports.

"Go on."

Rob glanced at the unicorn, and after confirming that Prinz Eugen meant no harm, he finally straightened his attitude and prepared to have a proper talk with the iron-blooded ship in front of him.

"As everyone knows, the sirens of today are nothing more than vessels."

"The only way to completely defeat them is to find the location where their true forms are hidden."
