The system is the king of the counterattack master

Everyone in the room looked at Sister He in surprise. Although they knew that rescue was imperative, they didn't expect it to come so soon.

"Let's...shall we make sure that Zhou Hao is really there?" The fat man said hesitantly, but from his tone, it could be heard that he had no confidence in saying this.

After hearing what he said, Sister He reached out to him: "Give me the phone."

The fat man was stunned for a moment, but he didn't dare to refute, so he obediently took out his phone, unlocked the combination lock and handed it over.

Sister He swiped the phone a few times, then pressed it lightly, turned the phone on speakerphone, and put it on the table.A familiar voice came from the phone: "The phone you dialed has been turned off."

She didn't hang up the phone, she just let the voice keep repeating between Chinese and English, then turned her head and asked Xueqing: "How long has it been?"

"From last night to now, I have searched everywhere, no, I just came to you today to find a solution after thinking of his abnormality a few days ago." Xue Qing was obviously anxious when she heard the voice on the phone. Been tormented by this sound for a long time.

"You should know that Zhou Hao's mobile phone is usually turned on for [-] hours, and it is never turned off. The sudden incident and the fact that he took away his own equipment bag proves that he doesn't want us to find him." Sister He Pressed the phone and hung up the call.

"Then maybe he is in a place where there is no signal." Gao Hui guessed.

Sister He glanced at Gao Hui, shook her head, and while fiddling with Fatty's cell phone, she said:
"Impossible, he must have turned off the phone on his own initiative. This is related to the technology of the mobile phone. The mobile phone we use must pass through the signal base station to exchange signals. A reminder, indicating that Zhou Hao’s mobile phone has sent a shutdown signal to the base station, otherwise, the base station will only assume that he has reached a place with no signal, and remind you that he cannot be connected temporarily.”

After speaking, he returned the phone to the fat man.

Hearing what she said, Han Xiaodong immediately had a different impression of this Sister He. He always thought that she was just a violent motorcycle girl, but it seems that her knowledge is quite extensive. From this point of view, She still fits the status of a C college student.

"I'm still a little worried. Would it be too reckless for us to do this?" Gao Hui frowned, still very hesitant. His worry was not unreasonable. Several students, in a way that sounded weird, It takes a lot of courage to go to a place completely unknown.No, it should be said that one has to be reckless enough to do such a thing.

But Sister He shook her finger at him: "It's not us. If we can really open that door as this kid said, then only he, me and Duanmu will go down, and you will respond from above."

As soon as these words came out, Xueqing was the first to quit, she immediately stood up and objected: "No, I want to go down too!"

Sister He looked into her eyes, pressed her hand, and pushed her back to sit: "You can't hit you, and you don't have experience. Are you going to hold back?"

"Then why is Duanmu able to go?" Xue Qing was a little mad when she heard that she was not allowed to go.

"He is the president, and the safety of all the members is related to him. Besides, if there is any danger, I also need a backup."

The words were so natural that Han Xiaodong didn't even react for a while, but when he understood what Sister He meant, he looked back at Duanmuxiu, only to find that the latter's face had almost turned earthy.

"Well, I think that Chen Long is more suitable than me to be a backer. Look at his figure, if he encounters danger or something, he can resist it a few times more than me."

Duanmuxiu pointed at the fat man and tried hard to keep a smile on his face, but he really couldn't get that mood right now, so this smile was uglier than crying.

"Stop talking nonsense, you are the president, how could the president just push the members forward? Take your things and we are ready to go."

As she said that, she walked to a table first, picked up a rucksack from the ground, looked back at Han Xiaodong, and said to the fat man, "Chen Long, give him your equipment first."

The fat man was a little reluctant at first, but after thinking about it for a while, maybe he realized that what they did was really risky, so he reached out, took out a rucksack from under the table he was leaning on, and handed it to Han Xiaodong.

Han Xiaodong took the bag and asked what was in it, the fat man opened the bag for him and took out the things one by one.

This bag is not small, a bit smaller than a mountaineering bag, but the inside is stuffed bulging, and there is no shortage of things at first glance. Seeing the fat man pouring out everything, Han Xiaodong was sweating like a waterfall.

From wolf-eye flashlights, engineer shovels, daggers, and compasses, which are standard equipment for field adventures, to small daily necessities such as sewing buttons, they are all available. What makes him dumbfounded is that there is actually a book inside. Black Leather's Wilderness Survival Manual.

Han Xiaodong knew that this book was indeed a must-have book for survival in the wild, but they were in an abandoned building, and these things seemed useless.

But he thought about it for a while. Although the underground building is not big, no one can say what strange things will happen to it, and the most common thing in places with artifacts is strange things, so just prepare it, just in case it can be used.

After checking everything, Han Xiaodong found a strange thing. It was a small metal square box with a very rough shape. There was only a huge button and several speaker output ports on the front, and a metal clip on the back. There is neither a sign nor a data label on it, only an earphone jack and a small switch on the side, which looks like something made by myself.

"What is this?" Han Xiaodong picked up the box and looked back and forth, then raised his head and asked the fat man, "Radio?"

"Walkie!" The fat man replied angrily, "This is our special walkie-talkie. There is only one frequency band, a very hidden frequency band. You don't need to know which one it is. Just use it. It can save you when you are in danger." life!"

"You did it?" Han Xiaodong asked curiously.

Hearing this question from him, the fat man immediately showed a complacent look on his face: "Are you quite discerning? This is my most successful work. Although it looks inconspicuous, it actually has a small encryption chip inside." , and it can automatically adjust the frequency, there is no way to crack it at all, unless you have the same type of equipment, the number of this thing is limited, it is definitely the treasure of our society."

Han Xiaodong looked at the reactions of the people around him out of the corner of his eye, and saw that except for Sister He who rolled his eyes, everyone else seemed to agree with him, so he knew that the fat man was not lying.

"How far is the effective distance?" Han Xiaodong asked while holding the walkie-talkie.

"Five kilometers, definitely no problem."

Before he could finish speaking, Han Xiaodong turned on the switch, pressed the call button, and shouted into it: "Zhou Hao, please call back if you hear it, please call back if you hear it!"
