Magical Index: Become a Girl and Come to Academy City

Chapter 111 Triangular Positioning Method

Looking at the scattered figures, Xie Mei turned to Shokuhou Misaki and said proudly: "So? I told you I can do it."

After saying that, she even lifted her hair proudly.

But Shokuhou Misaki looked helpless: "Who told you to blow her up? That's not how you use nitro-hydrochloric acid. That thing is used to dissolve it. If you blow it up, it will still reassemble."

"Ah? I saw it said flammable, so I thought that's how it was used." Xiemei scratched his head embarrassedly.

Although the human figure was blown apart, it only changed its shape and not its properties. The liquid metal was still liquid metal and it returned to its original shape in a few moments.

But then the second can of nitro-hydrochloric acid was thrown over. This time, Xie Mei knew how to use it and sprinkled the nitro-hydrochloric acid on the figure.

A vigilant somewhere felt that he had lost half of his connection with the figure, so he simply gave up on this second figure.

It is important to note that the ability to control liquid metal is not more difficult the larger the amount, or easier the smaller the amount, but the easier it is to control the liquid metal when the amount is similar to its own volume and size. If the amount is smaller, it will consume more computing power.

The combat effectiveness of this half of the figure left behind was greatly reduced, and the difficulty of controlling it increased, not to mention that she was still using the body crystal. She simply gave up on this figure, since she still had more liquid metal anyway.

Taking advantage of this gap, Shokuhou Misaki breathed a sigh of relief, and Hokaze Junko also came over to show her concern. The three of them gathered together and took the opportunity to discuss countermeasures.

To be honest, there is no point in defeating this liquefied figure now. If it is just about defeating the figure, Runko Hokaze can do it alone.

But the real purpose is to hide somewhere and observe, the information on this person is the most important.

Shokuhou Misaki just thought of something. The liquefied human figure has no eyes or organs, which means it cannot see or hear, but can only move.

However, even though the skull camera was damaged, the figure was still able to observe the surrounding situation, which means that the figure had other ways to observe this place.

"Is this Academy City's broadcast camera?" Shokuhou Misaki said, looking at the spherical camera floating in the air.

However, if they want to find the exact number and track it among tens of thousands of broadcasting cameras, they are probably powerless to do so.

After thinking for a moment, Shokuhou Misaki explained how to find Keisaku Kanto: "You know the triangulation method, right?"

"Triangulation?" Hokaze Junko and Kyomi exchanged a glance, waiting for Shokuhou to explain her next plan.

The principle of triangulation positioning is to use two or more detectors to detect the target direction at different positions, and then use the principle of triangulation geometry to determine the position and distance of the target.

Judging from the current situation, Jingce sees that there is more than one can of liquid metal. This kind of thing is not a rare item, so there must be a third and fourth can.

If these liquid metals were considered points, then their center point must be where Jingce was looking, because she needed to control these liquid metals, while she herself was in a relatively safe place.

Apart from the first figure chasing us, we now know the location where the second figure appears. Then when the next two appear, we can use the triangulation method to regard the range of activities of these three figures as three points, and the center of these three points is the location to be alerted.

Finally, Shokuhou Misaki explained the specific plan: "That figure seems to be targeting me, so I just need to move around as bait, and then you, Hofeng, will hold the figure back while I lure out another one. That way, I can confidently calculate the location of Kyousaku's target. Do you understand?"

"I understand." Fanfeng Runzi nodded.

"I understand too." Xie Mei agreed.

Shokuhou Misaki frowned: "Who asked you that? What do you understand? Go home quickly. We can handle this kind of thing just the two of us."

Xie Mei said unhappily, "If I weren't there, how much could you have moved at that speed? And she can't stay by your side forever. If the situation just now happened again, how would you have dealt with it?"

Shokuhou Misaki's physical fitness is already very poor, and if she is asked to move around now, speed will indeed be a big problem. This is well-founded and there is really no point in refuting it.

"I'm sorry, Tenkawa-san. I had no choice but to drag your friend into this."

Shokuhou Misaki sighed and agreed reluctantly.

She then took out the remote control and used her ability to control both Hokaze Runko and Kaimei at the same time.

In this state, three people can share vision, hearing and reaction, just like one person, which can greatly improve action efficiency and information transmission.

The three of them were walking nearby, and sure enough, a figure appeared as expected.

Hokaze Junko immediately rushed forward to block them, while Kaimei carried Shokuhou Misaki and ran away.

This figure appeared three minutes after the previous figure disappeared, and based on the figure's movement speed, Shokuhou Misaki was also calculating its location in her mind.

According to the speed of three minutes and the average speed of the figure, the distance can be roughly calculated with the location where the figure appears as the dot, and a circle is created around it with this distance as the radius. Then the place where the figure is initially placed is somewhere on the circumference of this circle.

The same goes for the previous figure. Now we have the circumferences of two circles to estimate the placement position, and now we just have to wait for the third one.

Not long after, Kaimei pulled Shokuhou Misaki away, while Hokaze Junko started a fierce battle with the figure.

However, after a confrontation, the figure suddenly turned into a pool of liquid and accumulated on the ground.

This information was also transmitted to Shokuhou and Kamei through synchronized shared vision, and they immediately began to reset the timer, waiting for the third figure to appear.

A moment later, with a loud bang, a huge hole appeared in the wall in front of the two people, and a liquefied figure walked out from it.

Xiemei reacted quickly and threw the last two cans of nitrohydrochloric acid at the figure, but this time the figure seemed to have become more cunning. A large hole was left in the middle of its body, cleverly avoiding the attack of the nitrohydrochloric acid. The two cans of nitrohydrochloric acid flew directly over the figure and landed behind it.

Shokuhou Misaki didn't panic, but instead smiled triumphantly.

At this point, the locations of the three tanks of liquid metal were determined according to the locations where the three figures appeared and the circumference of the circle. With every ten meters as a point, the locations of hundreds of figures were listed around the circumference of the three circles.

After that, the data was sorted and calculated one by one, and countless locations for warnings were found. These locations were then distributed in the form of a dot matrix over a 50-meter area.

This fifty-meter area is the final calculated location of the alert, and the results of all the calculations were completed instantly in Shokuhou Misaki's mind.
