When night falls, the sky is cloudless, and when you look up, you can see the crimson double moon of Ishtar, one large and one small.

Vladimir actually caught several big fish on the seashore, which made many people look at him with admiration.

He is usually a "lewd otaku" with average grades and appearance, full of sexual harassment jokes, and many girls are quite disgusted with him, but he himself seems to be unaware, and he talks about his pornographic jokes to girls all day long.

He is indeed an otaku, but he didn't expect to be a veteran fan of wild survival, and he has participated in many wild survival activities, and now the situation is simply the home field for him.

Then, of course, everyone lit the fire and started grilling the fish.

The beach, the night, the sound of the tide, the bonfire, the grilled fish, this is simply the most beautiful thing in the world for teenagers and girls. After all, they were young and heartless, and soon forgot about their dangerous situation and began to play.

In a corner of the beach, Zhang Xiu sat alone at the tool table, fiddling with various electronic devices.

He wiped the sweat from his forehead and let out a long sigh of relief. The work finally came to fruition – a simple homemade microwave signal base station.

Zhang Xiu used to find some waste electrical appliances to repair and fiddle in addition to studying, so he can be called an expert in this field.

Now with Xiao Zuo, he can easily see the exploded diagram and circuit diagram of electrical appliances in his mind at any time, coupled with Xiao Zuo's extremely accurate mechanical arm, he is already an excellent engineer.

Zhang Xiu didn't have much self-consciousness about this, he just relied on his intuition about electrical appliances and began to practice his ideas.

Previously, he found that the long-wave and short-range communication between mobile phones is still effective, so it stands to reason that microwave communication, which is the main signal of mobile phones, should also be effective. As long as there is a high enough signal relay base station, at least in their island, mobile phone communication can still be maintained.

At this time, Sixteen Night quietly walked to his side, sat down, lifted the black hair on his sideburns, pointed to the device that Zhang Xiu had just made, and asked, "What is this?" ”

"A microwave station," Zhang Xiu replied after glancing at Sixteen Nights.

This quiet oriental girl once made a deep impression on him. On the day of the hostage-taking case, the sixteen nights suspended in the air were extremely gorgeous and crazy, turning the tide of the battle with absolute power.

"Why don't you go play with them?" Zhang Xiu asked curiously.

"I'm not like them." Sixteen Nights said lightly, "You're not like them. ”

"Me?" Zhang Xiu raised his eyebrows and pointed to his nose.

Sixteen Nights nodded, but did not speak.

Zhang Xiu continued to debug the microwave signal base station. Sixteen Nights seemed to have infinite mysteries on his body, and Zhang Xiu was also curious, but out of the inherent caution and caution of a pariah, he subconsciously wanted to stay away from this girl.

Sixteen Nights quietly watched Zhang Xiu's work, and suddenly said, "There are two people on you." ”

Zhang Xiu turned his head sharply and looked at Sixteen Nights in disbelief. What is she referring to? Is it the existence of Xiao Zuo?

He smiled disguisedly and said, "What are you talking about?" I don't quite understand. ”

Sixteen Night didn't explain anything, she just sat silently and looked at Zhang Xiu.

As far as her eyes could see, Zhang Xiu actually had the illusion that even his soul had been seen through, and his whole body couldn't help but shiver.

Zhang Xiu didn't dare to look at each other with Sixteen Nights anymore, he hurriedly found an excuse to find something to find Teacher Karenna, stood up and trotted away.

What he didn't know was that when he turned his back to Sixteen Nights, from behind his left arm, a mechanical eye opened, and that mechanical eye looked at Sixteen Nights for a moment, and then disappeared again.

。。。。。。

Kalena's mobile phone rang suddenly, she froze for a moment, and then was pleasantly surprised to connect.

"Hey, hey, hey? Hello, who are you? ”

"Teacher Karena? It's me. Zhang Xiu said on the other end of the phone.

Karena looked up and found Zhang Xiu smiling and waving at herself in front of her.

She originally thought that the communication with the outside world was connected again without knowing what's going on, but it turned out that Zhang Xiu was joking with herself. Under the alternation of surprise and disappointment, it was inevitable that her mood became a little dissatisfied, she looked at Zhang Xiu, thinking to herself why she had never realized that this kid was so hateful before.

Karena hung up the phone angrily and walked over to scold Zhang Xiu: "Why do you make such jokes all day long? The teacher thought that he could talk to the outside world on the phone, and he was so shocked and happy by you, do you have to get the teacher to have a heart attack? ”

Zhang Xiu realized that his behavior was inappropriate, and he was a little uneasy by the words of the sixteenth night just now, so he was obviously a little ill-considered.

Zhang Xiu scratched his head and said, "I'm sorry." But don't you have any doubts, teacher? Why can I get through to you? ”

Only then did Karena remember that she couldn't even use a satellite phone, so why could an ordinary mobile phone get through?

"I used a simple tool to build a microwave relay base station, in which our mobile phones could not communicate with the outside world, but they could communicate with each other." Zhang Xiu explained.

Karenna's eyes lit up, and she realized the great value this thing could have for their current predicament, and she forced her excitement to ask, "Then how much range can the base station you make cover?" ”

"It depends on the height, after all, this is an experiment, and if you put it on a tall tree, communication within 100 meters should not be a problem."

Before Karena could express her regret, Zhang Xiu continued: "If I can get the radar antenna on that crashed spaceship, I may be able to make a powerful enough to be placed on the highest peak on the island at that time, maybe covering the entire island." ”

。。。。。。

When the classmates were full of food and drink, Karena Ye Zina and Zhang Xiu gathered the whole class.

“…… Although we are trapped here, we have to trust that our relatives and friends outside will definitely find out about our condition. So as long as we can live, we have the hope of being rescued. Karena analyzed the situation in detail with everyone.

Then she introduced the simple microwave base station made by Zhang Xiu, and continued: "So there are three most important things for us now. ”

"The first thing is to make sure we survive safely, which is not much different from our original wilderness survival training, which requires collecting water and food, and avoiding attacks by dangerous wildlife."

"The second thing is that we need to find the five missing classmates."

"But before we do that, we need to get to that crashed ship, which has weapons, equipment, and a lot of tools that will help us stay alive."
