"Di-Di-Di-——......"

Blaring sirens rang out throughout the building.

The sound of panicked footsteps mixed with sleepy-eyed whining and cursing suddenly made the otherwise peaceful command center a mess.

Soon, the military and political dignitaries of the purification system on the island were all gathered in the monitoring hall, and the service personnel at all levels were assembled and waited for instructions.

Everyone's eyes were on a swivel chair in the surveillance center. Sitting there is the commander-in-chief of the purification system mission site, Takeshi Nishino, who is both the head teacher of Group B for 3 years and the leader of the game organizer.

His whole body was trapped in the swivel chair, still looking at the ceiling with a blank face, and occasionally his face would twitch inexplicably, which made people feel more and more terrifying.

There was a deathly silence, and no one dared to gasp for air.

Especially tonight's night watchman, the glasses man and the flat-headed man, their faces were swollen red, their chins were almost buried in their chests, and they seemed to be able to see white water vapor rising from the top of their heads.

Takeshi Nishino was still looking at the ceiling, and said without warning, "Some of them are busy this time." It's completely different from the previous scene. Everyone is working harder, although the results are still unclear......"

The glasses man and the flat-headed man's shoulders moved suddenly, and when he wanted to interject for a review, he saw Takeshi Nishino wave his hand to stop the two of them.

"I didn't expect there to be such a strong character in Group B for 3 years, it seems that I underestimated them before this. Let that transfer school called 'Shinoda' may also be a failure!"

"It's no use to say more, the participants have blackened the glass of the 'observation box', and getting their latest updates is the priority right now. In addition, patrols around this command center should be strengthened, and if there is any abnormal situation, it will be reported to the command level immediately. ”

"Bring up the list of survivors and personal information!"

The man with glasses immediately sat down in front of his console and tapped on the keyboard with a "snap", and the photos and personal information of more than a dozen female students appeared on the largest surveillance screen.

Everyone's eyes fell on the innocent photos on the surveillance screen - it seems that this group of girls is not much different from the previous "game participants", why can they make the scheming Takeshi Nishino so nervous?

Takeshi Nishino was still stuck in the swivel chair and silently stared at the list, but his eyes fell on the three lines of data of Maeda Dunko, Oshima Yuko, and Kojima Kana.

"Oh, computer whiz, precision mechanic, traditional pyrotechnician?...... Five hours ago, they were in ...... An abandoned warehouse next to this headquarters!"

"I see!

The flat-headed man pressed a few keys and turned the knob again.

The images of the four main cameras in the southeast, northwest and northwest are spelled into a "Tian" character, although the high-sensitivity night vision camera, because the night is thick, still see the shadow is enough.

Just when everyone was staring at the four split screens, vaguely and unknowingly, Nishino seemed to have discovered a new continent, leaned his head to the split screen in the lower right corner of the word "Tian", stretched out his finger and asked:

"What's that thing?"

The flat-headed man zoomed in on the live broadcast of the camera in the south to the entire surveillance screen, and the picture was still dark, and there was no obvious difference from the usual surveillance screen.

"Raise the ISO sensitivity!" Nishino ordered again.

After the image of the picture has been processed, one can see that there is a diagonal line on the picture passing through the entire frame.

"It was a fixed wire rope that was brought from the East Mountain, and the harvested crops were transported to the school by pulley from the experimental farm halfway up the hillside......

The expert and team leader of the system department replied from the sidelines.

"That's it......"

"Chief Nishino, I don't understand why you noticed an anomaly from the monitoring results of the data? I've seen the data records, and they aren't too different from the same time band as the day before. ”

The leader of the group saw the stitches and asked his own questions about Nishino's gathering of everyone in a hurry at night.

Takeshi Nishino put his legs on top of the swivel chair, crossed his legs and asked the team leader who asked the question, "It's because it's the same as the day before, don't you think this is a suspicion in itself?"

"This ......"

"After another day of mental torture and physical exertion, the indicators should have dropped significantly compared to the standard of the same period 24 hours ago. Moreover, people's physical and psychological qualities are very different, and each has its own merits. However, it is clear that there is no gap between these data, so it does not look like the real thing. And the waveforms of all voices and images jumped at 3:233:15 a.m......."

Takeshi Nishino was explaining his discovery endlessly, when the flat-headed man whispered a few words to the group leader with a solemn face, and the team leader's face sank suddenly.

He looked at the people gathered in the surveillance hall with a grim face, walked up to Takeshi Nishino, covered his mouth with his hand, and said in a very low voice in his ear, "It's a big deal." There's a call line hijacked by a 'game participant' and she's going to talk to you......"

Takeshi Nishino took a sharp breath of air and looked into the eyes of the group leader—it was full of helplessness and distraction, and the smug look on his face when he asked the question just now was completely gone, and all that was left was a cowardly expression that had no idea.

Even Nishino's expressionless face flashed with a hint of worry, and with this change alone, the team leader came to a conclusion - the current situation on the island could only be worse than he had expected!

It's fine if it's just a call line that has been hijacked, but what if there are other lines that have been hijacked by them? There is even the operation of various equipment in the control center......

He didn't dare to imagine it anymore, because it was clear that the consequences would be dire.

His throat trembled a little, and he tried to swallow a mouthful of saliva, but he tried to pull his neck several times, but to no avail.

Takeshi Nishino gestured to the ceiling for the flat-headed man to switch the line to the speaker tunnel in the surveillance hall, while holding the microphone in his hand when he usually broadcast island-wide.

"Smack!"

Nishino snapped his fingers, and the flat-headed man cautiously pressed a button.

"Squeak—"

A sharp overload noise roared in the surveillance hall, and many people immediately covered their ears, and then realized that it was an inappropriate move on this occasion, and immediately put their hands down again.

"Hey, hey, this is the head teacher Nishino, please speak!"

Nishino's voice was mixed with the sound in the microphone after the amplifier had amplified the volume, and his hoarse voice was even more unbearable. He pointed to the glasses man's keyboard, meaning to ask his subordinates to quickly find out the route and technology of the line hijacking.

"Hey, hey...... Morning, good morning!"

The voice of a timid girl sounded in the surveillance hall, in the same tone as when she usually asked her teacher for leave on school days. Probably she paid attention to the current time, although it was not yet dawn, but she still used a "good morning" to greet her.

The conversation was like an ordinary phone call between a student and a teacher, but everyone in the room sounded terrifying and weird, and even felt their hearts pounding!

"Didn't I usually tell you the rules of making phone calls? Whether it is the person calling or the person who answers, you must first report to your home! This is politeness, the most basic social etiquette! Who are you?"

"Ah, yes, I'm sorry......! I'm Watanabe Kotomo!"

Nishino raised his eyebrows: "Oh, it turned out to be Watanabe-san." What's the matter?"

"Mr. Nishino, may I ask...... Can we leave this island after dawn?"

"Hmm? Who do you think you're talking to? Are you tired of being crooked?"

“……”

There was an awkward silence on the other side of the line, like when a student who had been reprimanded by a teacher was unable to defend himself.

"That...... We mean it. Please think again!"

Watanabe finally picked up again, but before Nishino could answer, an unexpected change occurred on the surveillance screen!
