Umihara didn't say anything superfluous. He has always been a staunch supporter of pragmatism, and now that he has made a decision, he will never waste any more energy on useless words.

Standing on the chains of the gravel, Mitsuki Haihara and Yan Bi looked at each other.

It was his last attempt, and he wanted to see something in the way he looked at him. However, what he didn't expect at all was that Yan Bi actually avoided his sight directly.

Although, he didn't expect to get any information from Yan Bi in the first place.

The chains of the crumble began to move, as if the adhesive surface was changing, sliding up and down at a very rapid speed, reassembling its structure repeatedly. As a result of this action, Haiyuan's body is constantly moving in the hollow interior space. It looks like you're flying in a hollow space.

In the same way, the long hair that has spread out is repeated little by little, starting from each strand, and then wrapping around again to form a support. Her body was also constantly changing position.

Both deliberately kept a delicate distance from each other. That's because both sides are wary of the other.

The telekinetic power held by Mitsuki Haihara seemed to have a feeling of being unable to exert his strength for Ji Yanbi, who could completely disperse and change his body structure. However, it is also difficult for Ji Yanbi to cause substantial damage to Haihara Mitsugui. Because telekinesis is the most common ability, its range of applications is too broad.

The abilities of the two are completely different extremes. Her abilities are too rare to comprehend, and it's impossible to imagine how she will attack and defend herself. And Haiyuan's abilities are too common to be understood too deeply, and although he can imagine the various ways in which he can use telekinetic power, the number of these "various" may reach at least four figures.

This means that once the other party's estimate is exceeded, it is the end. However, this seems to be a simple thing for both parties.

Therefore, both of them changed their positions as much as possible, so that the other's thinking had to change passively as they moved.

This balance is bound to be broken. The question is only, by whom and in what way it ends.

Syllable!

As a result of the water jet sprayed from the roof pipes, a concrete slab hanging on the top floor, almost the size of two people, fell from it.

This probably became a fuse. Because at about the same time that this concrete slab fell, Mitsuki Haihara and Shiobi began their movements.

At the foot of Umihara, one of the chains of debris was like a wave line that rose to its maximum peak, and it was thrown directly in the direction of the Yanbi area.

Ji Yanbi's reaction to this was to completely ignore it. The chains were like whips on the rocks, making a crisp sound.

Although a few strands of hair were broken off by Yan Bi's loose hair, Haiyuan's attack itself was probably nothing at all.

It's still there, and nothing has changed at all. The blow of the chain, she could easily resist with just a physical enhancement, the only effect was to distract her from the blow for a moment. Her gaze didn't stay on the chains for long at all. She just looked at Mitsuki Umihara as if she was asking for something.

Umihara manipulated the chains of the gravel to sink himself. Then, as if he had been bounced up by a chain, he flew in the direction where Yanbi was.

This move seems very abrupt, and even somewhat unclear. This seemingly blind behavior made Ji Yanbi overwhelmed by the accident.

Still, she was barely able to react in time the moment Kaihara's flying kick hit her. Yan Bi's body was like a ball of threads that suddenly opened, and the girl completely turned into a flying thread in an instant. Immediately after, the thread quickly retracted and quickly wrapped around Kaihara's body.

The ability of Yan Bi is too peculiar.

But then, something very surprising happened.

Because Haiyuan's body was also shattered into countless pieces in an instant.

What's going on?

Salt Bi was completely stunned. However, as soon as she regained her form, she immediately felt another kind of surprise.

She was grabbed by an invisible force that lifted her body up and down like a giant hand.

It was thrown directly to the ground from a height of nearly 40 floors, raising a large amount of concrete smoke. In the higher place where she was before, the figure of Kaiyuan slowly appeared.

He's been there since the beginning, and he's been there quietly since the first volley.

This is not a contradiction, there is no contradiction at all. Because the figure in front of Yan Bi's eyes is false.

Haiyuan is not an illusion powerhouse, but the scope of application of telekinesis is too wide. He just glued together the fragments of the floor slab with telekinetic power, and then used telekinetic manipulation to cover the water everywhere on it, using the refraction of light to construct a false form. As for himself, he hid his figure in the same way at the same time as that attack, and climbed directly to the upper position along the inner wall of the building through telekinematic attachment.

The biggest weakness of Shiobi's physical transformation ability is that she doesn't have a reliable long-range detection feature, so she has no way to know the true situation of Haiyuan.

This is often the case with the duel between the capable. In particular, the duel between those with roughly the same level of ability is almost a contest of imagination and vigilance.

Loosening the chains of the shards, Umihara fell to the ground. The mental power that is constantly working is released along the way, gluing and dispersing the water, debris, and building little by little. He stood on top of the mixture of water and debris, slowing down the fall so that it wouldn't go too fast.

By the time it was close to the ground, the falling speed had been reduced to almost no effect. He stepped on the ground covered in rubble from the slabs, just as he was breaking free from the pile of rubble.

Looking at Yanbi who had risen from the rubble, Kaihara shook his head.

"Tell me what's going on, Sister Bi. Also, what you just mentioned, it should be Hoshikawa of Tokiwadai, right? What does this have to do with her? What role did she play? ”

"What you really care about should be the back part, right?"

“……”

"Sure enough......"

"I'm not going to deny that. Senior sister, you are my senior, you may not realize it. After all, I am an older brother, and it is impossible for me to ignore the dangers that may exist around my sister. ”

"Yes...... I understand it very well. Hikari, you're the kind of older brother who is quite idealistic, and you're probably going to protect your sister at all times...... I sometimes even think, why aren't you my brother? Hehe, that's an unrealistic delusion. ”

As she said this, Haiyuan's face turned slightly red.

"But these are not conflicts, Senpai. You're worrying me too, and you should be aware of how abnormal you are right now. ”

"Yes...... I'm not normal at all. So, can you save me? ”

She looks like she's going to cry at any moment.

“…… Admit defeat, senior sister, you can't win. ”

Haiyuan looked at her wordlessly for a moment, and said in a helpless but extremely affirmative tone.

"Light, you haven't won yet."

"You still don't get it? Senpai. You've already lost. ”

Mitsuki Haihara didn't make any movements, his hands hung casually at his sides, and he didn't even clench his fists. His feet were just standing normally, and he didn't even pose in a position that was easy to exert force. It looks like there is no intention of fighting.

But that's what he said with conviction. There is no reason at all, but it seems surprisingly credible.

The earth beneath his feet, piled up with shards of the floor, rumbled as if in response to his words.

Earthquake?

No, it's not. It felt like something was flowing underground.

"Sister Bi, you live on the 41st floor, there is something you should be able to think of. How did you get the tap water you used to get to such a high altitude? ”

Yan Bi froze. At this moment, she realized Haiyuan's plan.

But what about realization? There is no time to react at all.

Tap water, pressurized by eight pumps at the bottom of the building, erupted from the ground under the control of Kaihara's telekinetic power. Before he had time to react, he was instantly swept into the air by the water pressure.

It's not a big deal, but ......

Although it has been repeated again and again, it is important to emphasize it again. By definition, telekinesis is defined as the ability to manipulate objects from a distance. The object in this definition is not limited to solids.

The jets of water that erupted from the ground and the splashes that fell from the building were combined by a powerful telekinetic force. In the blink of an eye, it became a huge water balloon that completely encased the salt.

(This...... This is...... ）

"It's not easy to capture you who are free to change your form. However, it doesn't have to be more difficult than catching a certain gas. Sister Bi, your grades are very good, you should know how to collect a certain gas produced by chemical reaction in the laboratory, right? That's right, that's the use of liquids. ”

Haiyuan said lightly.

Only what can change the form arbitrarily can capture what can also change the form at will. Rationally, it's not complicated at all. But when you think about it, it's terrifying.

Think about it, the key to this is that the process must be completed completely within the reaction time of the Yanbi. What does it depend on to do this in the blink of an eye? It depends on the series of arrangements that Haiyuan begins with the perception of water droplets on the wall.

Defeating the inner structure, called the counterattack, actually hides the body, suddenly throws the salt bi to a suitable position, and then penetrates the underground water pipe at this location in a directional way, and immediately moves the liquid to capture it...... And so on and so forth.

Although this is due to his understanding of the structural layout of the building, the meticulous thinking and calculation in the process have reached the point of being unbelievable. Blasting Mechanics, Fluid Mechanics, Elastic Mechanics, Structural Mechanics, Fracture Mechanics, Optics, Gas Dynamics...... And so on and so forth. Although everything used is not too complicated, it is hard to believe that Mitsuki Kaihara has completed the calculation of these contents in such a short period of time.

(Goo...... ）

"Also, you know the common sense that liquids are incompressible, right?"

And, as if he was trying to grasp something, he shook his right hand.

(Woooooooo Ahh......hh ）

The water balloon was squeezed inward by a powerful telekinetic force, and the incompressible nature of the liquid caused this huge pressure to act completely on Yan Bi's body. The theoretical upper limit of 3,450 kilograms per square centimeter is a huge pressure, and even if it can't be reached, it is definitely not something that a girl's body can withstand.

"Let me guess, how will you get out? Speaking of which, I did think of a solution. ”

The outline of her body became blurry and ambiguous, and she seemed to be trying to make herself oozing out of the water balloon after turning herself into liquid. But Umihara clenched his hand tighter again, and the liquid sphere inside the water balloon shrank sharply.

"Rayleigh-Taylor instability is a relatively common instability in fluid mechanics. The equilibrium of fluids of different densities is disturbed, eventually causing the light to rise and the heavy to sink, just as the tongue of mercury squeezes water into the water. In order to be able to grasp this phenomenon and isolate liquids of different densities, I asked my sister to help me several times. Because you should also know that the most common cause of disturbance is gravity. ”

The liquid that Yan Bi had turned into was completely restrained by the telekinetic power that filled the interface between the two liquids, and he couldn't move a bit. After several unsuccessful attempts, she had to transform back into a human body.

"I said it, Sister Bi. You can't win in any way. Did you beat me in physics? In particular, in the field of fluid mechanics. If this single subject is concerned, I am confident that I will be able to pass the Landau Theory Essentials exam. You shouldn't be able to do that, right? ”

The sphere made of water is like an impenetrable cage.

"Let me think about what else is possible. You ......"

Before the words fell, Haiyuan's eyes widened instantly.

Something bright red in the water balloon is seeping into the liquid. In an instant, a white mist filled the entire building. And, something seems to be glowing in the water balloon?

That kind of bright ...... Scorching light?

"Senpai...... Do you ...... It turned out to be ......"

Umihara's words were not able to continue.

Because a second later,All the recorders in the school park city will record such a terrifying scene:

Once the largest residential area in the 19th School District, it was razed to the ground in an incredibly large explosion of unknown cause.
