Check all the information thoroughly.
[Are these parts purchased? They bought them from several different companies, which is quite cautious.]
Hayama Kazuto couldn't help but smile.
"Check Argus and Rect again to see if there is any missing equipment." Yushan Heren said.
This possibility is not high. Given the technical capabilities of Argus and Rect, it should not be difficult to add a positioning system to the device. After all, if a device is lost, wouldn't that be a trap?
Kayaba Akihiko would not do such a thing, but for the sake of caution, Yushan Kazuto still checked it out. Maybe some devices don't have a positioning system added?
After checking, Yushan and others felt much more relieved.
"Can you make two signal shielding systems and two electronic jamming systems?"
This number seems a bit strange, but considering how cautious Kayaba Akihiko is, it is understandable.
[Two sets of equipment, really cautious. ]
Yushan Kazuto smiled.
[The locations where the information suddenly stopped in the video also seemed to be in two different places. ]
"Hui-chan, extract the coordinates of the areas where the information is interrupted in all the videos and mark them on the map." Yushan Heren said.
Two sets of concentric circles slowly appeared on the map, both located in the areas that Yushan Kazuto had previously suspected.
[Concentric circles? Is it because the strata have different attenuation levels for signal shielding and electronic interference? ]
Chapter 1073 Approaching the Truth
[Whether it is a signal blocker or an electronic jammer, the power is not low, and the theoretical effective radius is about 300 meters. ]
[However, according to the analysis of the video display, the shielding and interference radius of the two locations are far from reaching 300 meters, simply because the shielding area and the interference area are an ellipsoid, and the center of the ellipsoid is underground. ]
Yushan Kazuto was analyzing while performing mathematical modeling.
My usual hobby of modeling has produced good results this time.
[The measured radii of the shielded area and the interference area are also slightly different, because the attenuation of the strata to the two is different. ]
[By combining the two areas, we can get the attenuation coefficients to be and respectively. If we ignore the error, we can calculate that one area is about 15 meters underground and the other area is about 25 meters underground.]
Yushan Heren blinked. There must be some errors in this number. After all, he had not conducted any field measurements. He simply made an estimate through modeling. However, the reference significance of this number was still enormous.
"Hui-chan, analyze all the pictures and videos and look for areas similar to caves and cracks in the ground." Yushan Heren said.
Hui-chan processed the information quickly. There were only two locations that looked like mountain cracks in the picture, which made Yushan Heren shake his head.
Although these two mountain crevices can allow people to enter and exit, they are too small after all. It is somewhat difficult to store supplies and build a secluded place in the crevices.
Yushan Kazuto blinked slightly and asked Hui-chan to mark the location of the mountain gap.
The distance between the two crevices is about seven kilometers. These are the only two crevices and caves within a radius of ten kilometers.
Excluding the possibility that Kayaba Akihiko entered the cave from a distance, the only explanation is that Kayaba Akihiko's hiding place was built by digging a hole.
[But digging a hole this deep shouldn't be a small undertaking.]
Yushan Kazuto blinked. There are two possibilities now. One is that when Kayaba Akihiko was digging and building the retreat, no one discovered it. The other is that Kayaba Akihiko was digging and building the retreat as part of a legitimate project.
"Hui-chan, can you check if there have been any construction projects carried out in the Central Highlands in recent years?" Yushan Kazuto spoke again.
A few more pictures suddenly appeared on the screen. It showed that a high mountain hot spring hotel was built not far from the site of the outing.
The hotel began construction eleven years ago and was not officially completed until two years ago.
Due to insufficient hot spring water, the project almost became an unfinished building. Fortunately, a new water source was discovered later and construction resumed.
This alpine hot spring hotel is also a sponsor of this outing. Soaking in a hot spring after an outdoor outing is a very enjoyable choice.
【Looking for water? 】
Yushan Kazuto smiled.
In addition to natural hot springs, people usually look for hot spring wells in the mountains.
The deepest hot spring well can even be drilled to a depth of four thousand meters. A location like Kayaba Akihiko's, which is dozens of meters deep, is likely to be a wellbore that was abandoned after the initial drilling of the hot spring well.
"Hui-chan, check again to see if there is any drilling record related to the Baiyun Hot Spring Hotel." Yushan Heren said.
Soon, Hui-chan's voice rang in my ears: "No, it's not available on the Internet or on the storage hard drive in the hotel."
"Then let's continue to check. When did the hotel start construction again?"
Hui-chan gave a time, and Yushan and Xinxin calculated that it was about four years and three months ago.
[That is to say, the drilling time should have been four years and three months earlier.]
After all, the hotel has to find hot spring supplies before it can start working again. If you calculate the time this way, it seems to coincide with the time when Kayaba Akihiko started preparing a hiding place.
Yushan Kazuto blinked slightly. It seemed that he had to find a way to contact the person in charge of the hot spring hotel.
Taking out his cell phone, Yushan Kazuto called Yushan Yayoi.
"You little brat, you actually knew to call me? What trouble has happened again?" After answering the phone, Yayoi Yuyama spoke.
"I would like you to help contact the Baiyun Hot Spring Hotel in the Central Highlands to see if there are any records of drilling hot spring wells a few years ago." Yushan Heren said.
"Why are you asking this?" Yayoi Yuyama felt a little confused.
"It's related to Kayaba Akihiko." Yushan Kazuto said.
Yushan Yayoi blinked slightly. He knew that Yushan Kazuto might have found some information.
He has also been searching for information about Kayaba Akihiko, but due to obstruction, the progress has been unsatisfactory.
"I understand. I will contact them." said Yayoi Yuyama.
"Okay, I'll hang up first. I have to eat." Yushan Heren hung up the phone and stretched.
Listening to the "beeping" sound of the phone, Yayoi Yuyama shook her head, put down the phone and continued eating dinner.
"Hui-chan, clear all traces and try not to leave any clues." Yushan Heren gave an instruction and stood up.
Whether it's Kayaba Akihiko, Sugo Nobuyuki, or even Kamishiro Rinko, they are all experts in hacking technology. If they don't take safe measures, the other party might catch some clues.
I opened the door and walked out of the room. Izumi Sagiri had already finished eating and returned to her room. Only Doma Mai was left sitting at the table, sulking.
"What's wrong? Judging from your expression, it doesn't taste good?" Yushan Heren said.
"Scumbag senior, what are you doing staying in your room all the time?"
He puffed up his cheeks and looked at Yushan and others.
"I was reading an article just now, and I happened to see a key part. Some inspiration popped up in my mind, so I couldn't get up." Yushan Heren explained.
Tsuchima pouted. She felt that Yushan Kazuto was just forcing an explanation, but she had no way to refute it.
After all, she had seen Yushan and others reading articles, and those were articles written purely in German. She also knew that when inspiration came, people didn't want to be disturbed.
Doma Mai could only lower her head, pick up a piece of steak and start eating.
"Okay, okay, don't be angry. I'll take you out to buy a comic book later?" Yushan Heren said.
"Mayu-chan is not that easy to appease!" Mayu-chan snorted.
The main reason is that I have already bought this week's issue of "Weekly Shonen Jump", and next week's issue will not be released until Monday.
"How about I take you for a ride?" Yushan Heren smiled.
There has been great progress in the information about Kayaba Akihiko, and he is in a very good mood now.
"Let's go ice skating!" Tsuchima said suddenly.
"Hey, can you ice skate?" Yushan Kazuto looked at Doma Mai with some doubt.
"Don't underestimate Yumi-chan!" Yumi-chan snorted again.
"Well, let's go ice skating," Yushan Kazuto said, "I'll check the nearby ice skating rink."
"No need to check. A new Silver Light Ice and Snow World has opened nearby." Tsuchima smiled, with an expression as if her evil plan had succeeded.
Chapter 1074: Can You Give In?
Silver Light Ice and Snow World has been open for less than a week.
Doma Mai had wanted to go for a long time, but had never been able to do so because she was short of money. Today, Yushan and his friends said they wanted to take her out to play, and she immediately thought of this place.
"It looks good, but I don't know what the facilities inside are like?" Looking at this huge ice and snow world, Yushan Heren couldn't help but blink.
After passing through a glacier corridor, we arrived at the cashier counter. The tickets were quite expensive, no wonder Domama couldn't afford it.
A single ticket is 2,200 yen, or you can choose a timed card, which is 950 yen per hour. As for which one is more cost-effective, it depends on your personal love for skating or skiing.
"Let's get two single tickets," Yushan Heren said.
Although it is highly likely that you will not skate for three hours, the time card will be rounded up. Even if you only skate for two hours and one second, you will still be charged for three hours.
In order to avoid trouble, Yushan Kazuto chose a single ticket.
"Do you have any suitable equipment? If not, you can rent it for an additional 300 yen!"
The cashier at the front desk said very politely. Yushan Heren blinked slightly. Since he had already paid the 2,200 yuan ticket price, he didn't care about the 300 yuan rental fee.
The main reason is that Yushan and his men’s equipment are all in Chiba, otherwise there would be no need to rent them. As for Doma Yui, she doesn’t have these things at all.
"If I want to change to ski equipment after experiencing ice skating, do I need to be charged again?" asked Kazuto Yuyama.
"No, three hundred yen already covers the usage of both equipment," the cashier said politely.
Yushan Kazuto nodded and looked at Tsuchima: "Umi-chan, do you want to skate first or ski first?"
Looking at the steep downhill slope in the ski resort, Tsuchima felt a little timid: "Let's go ice skating first."
"It's more painful if you fall on the ice rink," Yushan Kazuto reminded.
The ski resort is covered with fluffy powder snow, so if you fall it's soft and won't hurt too much, but the ice rink is covered with solid ice, so falling on it is no different from falling directly on the concrete floor.
Doma puffed up her cheeks and looked at Hayama Kazuto: "Mamoru-chan wants to skate!"
Just looking at the ski slopes in the ski resort, Domama felt a little nervous.
"Okay then." Yushan Kazuto shrugged.
In fact, he didn't think it mattered, because he was good at both skating and skiing.
Since it was a newly opened ice and snow world, most of the things had not been used. Yushan and others made a special inspection and found no strange smell, so they put on the foot covers and put them on.
After putting on ice skates, Domama was a little unsteady on her feet. Her thighs were taut and pressed tightly together, and she took cautious steps.
……
"I'll go for a few laps first, and you can try skating on your own, is that okay?" Yushan Kazuto asked as they entered the ice rink.
"No, don't underestimate Yume-chan!" Yume-chan snorted.
"Then... see you later." Yushanhe waved his hand, accelerated, and rushed out like a flash of lightning.
Due to long-term exercise and football playing, Yushanheren's muscle explosive power is naturally very strong. What is even more commendable is that, in addition to muscle explosive power, Yushanheren's balance and endurance are also exceptionally good.
Yushan Kazuto's skating posture may not be very elegant, but it is simple and rough, full of violent aesthetics. You can even hear the whistling of the wind as it passes by.
Yui Doma was at the edge of the ice rink, holding onto the handrail and trembling with fear. Although she was very careful, she still fell several times.
When I watched TV in the past, those people skated very naturally and gracefully. I thought ice skating was very simple. But after I actually tried it, I realized how difficult it was.
Fortunately, with the insistence of Yushan Kazuto, Doma Mai wore a full set of protective gear, even a hip protector.
Originally, I thought the style of the hip protector was a bit ugly, but now I know that this thing can save lives.
Otherwise, with the few falls she had on the ground, it would have probably broken into several pieces.
Tsuchiya Yui's actions naturally attracted a lot of people's attention. After all, such a cute girl who can't even skate, naturally there would be people who want to show off in front of her.
"Hello, do you need help?"
A boy shook his hair, struck a pose that he thought was pretty handsome, and slid over.
Doma Mai blinked slightly. She really wanted to say that she didn't need help, but she couldn't even keep her balance. Wouldn't it be embarrassing to say that?
[Damn it, where did that scumbag senior go? ]
Tsuchiya glanced around, but for a moment he wasn't paying attention and almost fell again.
