Azur Lane Mobile Front.

Although the clock had long since struck midnight, Bismarck's office lights were still on.

"Cough cough~"

Bismarck, sitting at his desk, couldn't help but cough twice.

Because of the "deterioration" of the Rubik's Cube, her physical condition has never been ideal.

Although the latest shipboard technology can alleviate some of the symptoms.

However, it cannot be completely cured in the end.

Her current condition is like that of a terminally ill patient, with her body constantly connected to various medical instruments.

Although she can survive for a short period of time, she will eventually succumb to the strain.

"Is the royal family trying to make contact with the Eastern Huang?"

"Ha, so you're finally going to let go of that unrealistic air of yours?"

A faint smile played on Bismarck's lips as he set aside the intelligence regarding the Royal Navy.

She looked up at the wall clock, then at the unfinished documents on her desk.

Because Luo had recently attended a meeting at the Northern Union, Bismarck's desk was piled high with intelligence about the meeting.

To some extent, Rob's casual hopping around only adds to the workload of this iron-fisted prime minister.

"Miss!"

Just as Bismarck was about to work on the next document, a lively voice rang out in her office.

Along with the sound, a petite ship with blue hair in short pigtails and dressed in very revealing clothing appeared at the door.

"Hmm? Is that U-556? Why aren't they asleep yet?"

Bismarck put down his pen, a gentle smile on his face, and looked at the submarine that had always been following him.

"Big sister, you are the one who is!"

U-556 rushed to Bismarck's desk, only to be startled by the mountain of documents piled up on it.

"Hey? Big sister, you're not planning to finish all this before you go to rest, are you?"

"...No, I'm going to sleep right away."

A fleeting look of surprise crossed his face.

In the past, U-556 rarely said anything about his working hours.

What exactly happened today?

"really?"

"Of course!"

Bismarck lowered his head, using the excuse of handling documents to avoid U-556's suspicious gaze.

This iron-fisted prime minister was not particularly skilled at lying.

"Well... then... big sister, remember to go to bed early, I'll be going now!"

After staring at Bismarck's face for a while, U-556's lips twitched slightly.

Soon, the sound of the door closing came, indicating that the submarine had left.

"..."

With a sigh, Bismarck glanced at the empty teacup beside him.

"Perhaps I should try the coffee from Mainz?"

Even Bismarck couldn't help but smile wryly when she thought of the coffee flavor that the planned ship had always insisted on.

...

The liveliness on U-556's face vanished instantly as he stepped out of Bismarck's office.

Her eyes were filled with anxiety as she looked at the closed door behind her.

Judging from Bismarck's evasive manner just now, it's not hard for U-556 to tell that the other side is lying.

"I've said it before, she's very stubborn."

"Even I couldn't persuade her to share the workload as much as possible."

Prince Eugen leaned against the door, watching U-556 emerge from Bismarck's office.

It seems the two had said something before this.

"...Is there really a way to let my older sister get some rest?"

U-556 looked at the still brightly lit office with some worry, his fists clenched so tightly that his fingertips almost dug into his palms.

"Normally, no."

Princess Eugen had a smile playing on her lips; she seemed to be waiting for the small ship before her to make some kind of decision.

"Then what about your method?"

"Hehe, of course—that's possible!"

"Can you guarantee you won't hurt my older sister?"

"Little guy—"

The smile in Prince Eugen's eyes suddenly vanished.

She stared at U-556, her face seemingly covered with frost.

"You should know, she is also one of my few friends."

"Do you really think I would hurt my friend?"

Under the watchful eye of Prince Eugen, U-556 mustered its courage at this moment.

She glared back without flinching.

His small body was held upright.

"This concerns my eldest sister; I can't afford to make any wrong judgments!"

Mentioning Bismarck brings back those memories.

During that operation, U-556 was underwater and watched as the heavily wounded Bismarck slowly sank into the water.

She used all her strength, but could only drag the other person back.

After that, Bismarck fell into a long silence.

She never wanted to see that scene again.

"Then I assure you, Bismarck will be in no danger."

"My ultimate goal is to help her be reborn."

"Now, all we need to do is try to persuade her in a special way."

"..."

U-556 fell silent.

She bit her lip, staring intently at Prince Eugen.

At this moment, she seemed to be going through a strong internal struggle.

After a while, the lights in Bismarck's office were still on.

The Iron Chancellor did not go to rest as she had said.

Seeing this, U-556 finally made up his mind.

"I'm joining you!"

"Hmm~ Well then, welcome~"

Under the cover of night, two hands, one large and one small, clasped together.

Chapter 780: Yi Xian, whose mind is in turmoil

In an exquisite and elegant room, Yixian and Zhenhai sat facing each other.

A game of chess, which had reached a stalemate, was placed between the two players.

A wisp of smoke rose from an antique incense burner, filling the not-so-large room with a delicate fragrance.

Through the open door, a glimpse of the bedroom could be vaguely seen.

On a large bed, the quilt was neatly spread out.

The two identical pillows placed on the bedside table indicate that the owner of this bedroom is Zhenhai.

At this moment, Zhenhai held a teacup in one hand and calmly looked at Yixian, whose delicate eyebrows were slightly furrowed.

It has been a while since the last move.

Judging from Yixian's indecisiveness, it seems that there is still a slight gap between Yixian and Zhenhai in terms of chess skills.

After a short while, Yixian's tightly furrowed brows finally relaxed.

She picked up a chess piece and raised her hand to place it.

Just then, the door to the room was pushed open with a "bang".

"Sister Yixian! And Sister Zhenhai!"

"Something...something terrible has happened!"

Pinghai, who pushed open the door somewhat roughly, seemed to be breathing slightly heavily.

Judging from the looks of it, Pinghai ran all the way here.

"Pinghai, what happened? Why are you so panicked?"

Attracted by the sound of the door opening, the two turned their heads to look at it at the same time, and even Yi Xian's hand, which was about to place a piece, stopped in mid-air.

However, upon seeing that the visitor was Pinghai, the two refocused their attention on the unfinished game of chess.

"This...this is really a big deal!"

"Commander, I'm getting married to that big fox from Sakura Empire!"

"Crack~"

The sound of a chess piece being placed on the board rang out.

Yi Xian's hand trembled slightly at the last moment as he placed his piece.

This piece landed in a position it should never have been in.

Zhenhai raised an eyebrow at the sight, then looked up at her best friend across from her.

"You can take back your move now!"

"No, I understand the principle that once a move is made, it cannot be taken back."

Yi Xian pursed her lips and shook her head slightly.

"Pinghai, why did the commander suddenly bring this up?"

"I don't know~"

"Anyway, the news just came from the commander's office."

"I just saw that big fox walk towards the commander!"

"Is that so..."

Yi Xian spoke softly, her eyes already fixed on Luo Bo's office.

Although there was still a considerable distance between them, her gaze seemed to pierce through those obstacles.

"We understand."

"I have some snacks here, Pinghai, you can have them."

As he spoke, Zhenhai waved to Pinghai.

"Hmm~ No, I have to go see other people!"
