I'm doing abstract animation

Disappointment stemmed from the fact that Yukari's goals were completely unrelated to his own, but relief came from the fact that Yukari was honest and did not choose to hide her goals.

"Young man, what progress have you made so far?"

Although their goals are different, it does not prevent the two from cooperating. As long as there is no conflict of interest, Aizen is still easy to deal with.

"We've made some progress."

Yuki was also very satisfied with Aizen's attitude of getting things done right away; that was exactly what he wanted.

He immediately shared what he had gained with Aizen.

"The most important thing to travel between worlds is to have coordinates. To give an analogy, each world is like a grain of sand, and outside the world is the beach. You can imagine how difficult it is to find the grain of sand that originally belonged to you on the beach."

Aizen nodded: "So you mean that as long as you have a location, you can travel to that world, right?"

Yuki shook her head: "Of course it's not that simple. Finding your own grain of sand is only the first step. The second step is to break down the barriers between worlds. Simply put, the world has a self-protection mechanism. Each world has an outer barrier. This barrier is a product of the rules and is difficult to be destroyed by external forces. For example, the alternate dimension you belonged to before was a product of the barrier."

"While this might be difficult for you to solve, it's not a big problem for me due to my unique physical condition."

Special physical condition refers to a system carrier.

The system is a product that transcends the world, and its carriers can naturally move freely between different worlds.

Aizen nodded. He didn't ask why out of curiosity. He knew that there were some things he could ask and some things he couldn't.

"Besides the two points mentioned above, the next point is very important, and that is the distance between worlds."

"The outer ocean is too vast... Never mind, I'll show you around anyway."

After thinking for a moment, Yuuki decided to broaden Aizen's horizons.

This also serves as a chance to verify the research findings from this period of time.

Aizen smiled: "I'm looking forward to it."

Yuuki's eye twitched. This guy's really showing off...

With his hand on Aizen's shoulder, Yuuki Riki's free hand held a card. Before Aizen could even look at it curiously, he crushed the card in his hand.

Click...

The space in front of them collapsed instantly, and in just a moment the two of them found themselves in a starry sky.

It was like being in a boundless universe, surrounded by deathly silence. Even a cunning old fox like Aizen couldn't help but feel a chill down his spine at the sight of such silence.

"Don't look too closely. There are many terrifying things in the World Sea. Looking too closely will bring disaster."

Yuki reminded him.

Heeding advice and eating well, Aizen nodded, no longer looking at the pitch-black darkness, but instead focusing his gaze on the twinkling stars.

Countless stars were some near and some far away from them; some were so far away that they were just tiny dots, while others were so close that they could even see the details inside them.

What's inside the stars?

A star contains a universe.

"Incredible..." Aizen took a deep breath, a hint of joy in his eyes: "Is this the world beyond?"

"Look at your feet."

Yuki reminded him.

Aizen looked down and saw that the two of them were standing above a star.

This star doesn't look very big; no, it can't be called a star, it should be called the world.

The world is like a giant bubble, inside which is a universe with lifelike planets. But Aizen knew that what Yuuki wanted him to see was not this, but the densely packed micro-bubbles on the outer surface of the bubble.

"what is that?"

Aizen didn't think there was anything shameful about asking questions, as he believed that if you didn't understand something, you should ask.

"That's an alternate dimension, a dimension isolated from the world. You were in one of those dimensions before."

"Are these... all people from other worlds?" Aizen asked curiously.

“No.” Yuki Osamu shook his head: “Your situation is very special. Many of these alternate dimensions are developed from the world itself, but they are excluded because they do not conform to the rules of the world.”

That's enough. If you go on to explain further, you'll just have to repeat what you said before.

"Okay, take a look at that one now."

Aizen looked over following Yuuki's finger.

It was a bubble very close to them, but unlike the one beneath their feet, that bubble didn't have smaller bubbles growing around it.

The inside of the bubble is no different from this one; it's also a lifelike model of the universe.

Do you know how far it is from where we are standing to that other world?

Yuki sighed.

Aizen's expression also turned serious, and he gave his answer.

"It cannot be estimated."

P.S.: There will be another chapter later.

A City of Ghosts and Monsters: Chapter 31 Link Achieved

It is impossible to estimate; it is the distance between worlds.

It's important to understand that a world contains a universe, and the universe is virtually infinite. Therefore, the distance between worlds could be far greater than the size of a single world...

Aizen was a scientist after all, so of course he knew how big the universe was.

That's why he said the answer couldn't be estimated.

"Yes, it's impossible to estimate...that's what we need to address now."

Then both of them fell silent.

"Didn't your previous teleportation method work?"

Aizen suddenly asked.

He thought that such a skill that ignores spatial distance might have a surprising effect.

"...That requires coordinates to use."

Aizen: "..."

He was at a loss now.

First, you need coordinates to travel to a specific world, but to get the coordinates you have to get to that world... This is a double-edged sword.

"Let's go back first. To be honest, I actually have some ideas now."

Yuki took Aizen back to the top of Mount Fuji.

"What's next?"

Aizen asked, as he had always acted independently and this was the first time he had ever needed someone else's instructions to see what the next step would be.

It's kind of novel...

Yuki thought for a moment, then said, "I will teach you the energy system I have mastered, as well as the principles of teleportation."

"Let's test the waters with your original world first."

Aizen laughed. He didn't care at all that his world was being used as a test subject by Yuuki Rie, since he had nothing to miss in that world anyway.

"But this requires you to open your mind and establish a deeper bond with me, otherwise you may not be able to use my energy."

Yuki was not lying. Whether it was Yui Yuigahama or the others, the prerequisite for them to use energy was that they had established a connection with themselves. Otherwise, they could only use physical energy to drive the cards.

Energy is a product of the system. To master energy, one must establish a link with Yuuki and become Yuuki's subordinate. Only in this way can one utilize energy.

"Of course, that's how it should be."

Aizen had no objection to this; on the contrary, he quite agreed. In his view, energy was equivalent to his previous Hogyoku, and Yuuki's behavior was similar to his previous actions.

Yuki reached out and grabbed his wrist, and soon a small golden tree appeared on Aizen's left wrist.

Yuuki Osamu: "..."

He looked at Aizen with some surprise and doubt. This guy's connection was so smooth that there was no resistance at all, even more so than Yui Yuigahama's. It was simply unbelievable.

Aizen seemed to sense his confusion and smiled, "Isn't trust the most basic element of cooperation?"

For a moment, Yuuki was speechless. Seriously, is it really appropriate for a major villain like you to say something like that?

But this is good, at least it saves a lot of trouble.

"Next, I'll tell you about the usage instructions..."

............

Leaving aside Yuuki Osamu for now, let's shift the focus to a certain kendo prodigy girl.

"Drink!"

The bamboo sword struck the opponent's head with unstoppable force, producing a dull thud.

The person who was hit fell to the ground with a thud, seemingly disoriented by the blow, and it took him a long time to gradually recover.

"Minister, your kendo has improved again..."

Removing his kendo helmet, a burly man, pale-faced and panting heavily, said with a wry smile.

Saeko Busujima didn't say anything, but simply took off her helmet and sighed, looking melancholy.

She felt left out.

After experiencing the shopping mall incident some time ago, she was thrilled to learn that there are unknown aspects to this world.

She has a secret that no one knows: she has a strong tendency towards violence.

When Saeko Busujima was in junior high school, she was assaulted by a pervert on her way home from school. However, because she was carrying a wooden sword, she deliberately let the pervert get close to her and then used the wooden sword to severely injure him, breaking his leg bone and shoulder blade. In fact, it was excessive self-defense.

However, considering the social climate at the time, it was clear that the perpetrator was at fault for the junior high school girl confronting the perpetrator, so the police naturally did not pursue the matter further.

What no one knew was that she felt extremely excited and happy when she hit that pervert.

She knew very well that this aspect of her personality would never be accepted by society, so she always hid her true self.

But on that very day, the appearance of the monster, the power displayed by Miura Yumiko, and the blood-splattered battle between the two undoubtedly excited her to the point that she was practically in tears.

Ahem, of course, none of that is the point. The point is that I have already extended an invitation to them to join the team.

The next day, the students she knew from the same school all seemed to avoid her, whether intentionally or not.

Oh, no, there's a girl named Yui Yuigahama who's willing to talk to her, but she pretends to be clueless whenever she asks about it.

"Join the team?"

"Hahaha, Busujima-senpai, you must have misunderstood. I don't quite understand what you mean."

"What shopping mall incident? I'm not quite sure what you're talking about!"

Busujima Saeko: “…”

She was helpless in the face of this situation, after all, she was the one who needed their help.

'Could it be that they chose that girl from Toyonosaki?'

'That shouldn't be the case...'

She was quite confident in her combat skills. Her opponent was just a lousy light novel writer, completely incomparable to her, a three-time champion of the Jade Dragon Flag Singles Tournament.

But why are those guys all unwilling to give themselves a straight answer?

The thought of this made her feel a little irritated.

She hadn't felt this kind of urgent yet helpless feeling in a long time.

Seeing his minister's expression change repeatedly, the rugged-looking boy couldn't help but shrink back and secretly prepare to slip away.

During this period, he didn't know what had gotten into his minister; whenever his expression changed, he would get a beating.

"Dojima, where are you going?"

The burly boy froze, then turned his head shakily.

As expected, he met Saeko Busujima's icy gaze.

"Minister, Minister, I suddenly remembered I have some things to take care of at home..."
