The squadron leader and the others were stunned by this scene, they had only rushed over to guard the mine yesterday, and they had no idea what was going on below. When the superior leaders sent them over, they gave a death order not to go into the cave without permission and wait for the arrival of the experts. No one could have imagined that the warriors guarding the entrance of the cave would dare to go down the cave by themselves.

Simon Chain sighed and said to the squadron leader: "It's all swamp gas down there, and your soldiers are more auspicious." ”

"Who are you fooling! This is the Gobi Desert, which is dry and rainy all year round, so what kind of biogas is there! The squadron leader was not easy to fool, he pointed to the hole that was still emitting a foul smell, and continued: "My hometown uses biogas to cook vegetables, and this is not the smell at all. If you're not going to save people, get out! Come! Hurry up and get the gas mask, it's too late to go down and save people now......"

"Who said you can't use biogas in the Gobi Desert? Do you know how many types of biogas there are? There are six types of biogas, five of which are wetland biogas that is common in your hometown, and one is an underground air-dried biogas pellet similar to the one here. Seeing that the squadron leader was anxious to get into the room, Sun Desheng came over, took out the business card he had prepared and handed it to the squadron leader. It reads XX Chemical and Physical Defense Institute, chief researcher Sun Desheng.

When Sun Fatzi is not hippie and smiling, there are five people and six people who still look like intellectuals. Originally, he was the 'expert' that the squadron leader had to wait for, but now after seeing the business card, he has no doubts.

Seeing that the squadron leader did not have any suspicions, Sun Desheng pointed to the gas masks sent over and said: "You all have filtering gas masks here for chemical poison gases, which can only filter poison gas particles with particles smaller than 0.07. I can tell you responsibly that the biogas particles of this underground air-dried type are less than 0.05. Before the methane is cleaned, as many people as you go down, you have to leave as many people as you want......"

When the squadron leader heard that he was in a hurry, he said in a trembling voice: "Then don't save it?" Watching my soldiers die? No......"

"Who says you can't save it? To save people, we must also have the right way to save people. Sun Fatzi turned around and pointed to the entrance of the cave and continued: "Most of this underground air-dried biogas is of the stage compression type, and there will not be too much storage in the same area. As long as the poison gas is cleared, we can go down and save people. The short-term invasion of poison gas to the human body is limited, and it can only be rescued in time, and your soldiers can still be saved......"

After listening to Sun Desheng's words, the squadron leader remembered that he still had an exhaust fan, and hurriedly asked someone to lift the machine over and quickly discharge the biogas inside.

While the Wujing soldiers were busy, Psyllium came over, gave Sun Desheng a thumbs up, and said: "I can't see it, I thought you had a big belly full of fat, and I didn't think that you were also a little learned." This is all learned in the polling bureau? If you didn't, I didn't know there were so many types of biogas. ”

"I don't know anything about ......it," Sun Desheng grimaced at psyllium, and then continued to whisper: "What kind of biogas is divided into six kinds, and the poison gas mask does not filter it...... It's all made up by my brother, but the business card is real. Now if I go to the chemical institute, I can still find the name of my Sun Desheng. It seems that he has been promoted again, and he has been given the position of deputy director......"

Psyllium was stunned for a moment, then looked in the direction of the cave entrance and said, "The people in there ......"

"I've said it all, the fierce and auspicious ......" Ximen Chain leaned over, sighed, and said to Sun Desheng: "Great Sage, the following things may be more complicated than we expected. You are delicate and expensive, stay on it to answer, and after the people in our second room arrive, we will go down. ”

"Daguan, have you changed sex?" Sun Desheng glanced at Ximen Chain, then glanced at the psyllium who was nervously looking at the Wujing warriors, and then said slowly: "Look, I'll talk about it when the time comes." None of us are Director Wu, and no one can guess what will happen in a while......"

Just as they watched the Wujing soldiers try to expel the underground 'methane', the soldiers guarding the cordon brought two men and a woman, all dressed as scientific researchers. After inquiring about Sun Desheng and the professionals sent by their superiors, the three of them hurriedly came over to introduce themselves.

One of the older men was named Feng Haiyang, who was the deputy leader of the geological exploration team. Because of his age, he was responsible for answering on the ground, and he escaped. Another man is Wang Jiajia, the director of the Geological Bureau, and the person in charge of this exploration mission. After the accident, he was the first to rush over to preside over the overall situation.

The only young woman is called Li Weiwei, who is only twenty-seven or eighteen years old, but she is the previous person in charge of rescue. She stayed to connect with the personnel of the polling bureau for rescue operations, and it can be seen that because of the previous rescue failure, Li Wei was hit hard. He sighed and sighed......

After a few polite words, Simon Chain said to the three people: "We have read all the basic information, but I would like to ask a few people to recall if there is any part of the information that has been forgotten to describe." We want the details...... The specific details inside the cave, we need to know this. ”

Feng Haiyang took the initiative to say: "Leader, I am the first batch to go down to the underground mine rock formation, and then I am responsible for the response work up and down. It's not different from other rock formations I've been to, and it's just a normal depiction and sampling. It was smooth at first, who would have thought that something would happen at the end of the day. ”

What Feng Haiyang said was similar to what was in the data, it was almost the end of the exploration mission when a collapse accident suddenly occurred. Strange things basically happened in the process of rescue, and now most of the people involved in the rescue are undergoing psychological treatment. Li Wei took the medicine prescribed by the psychiatrist and reluctantly waited for the handover here.

Feng Haiyang of the exploration team has nothing new to say, and Wang Chuchang of the Geological Bureau has nothing to say. Only Li Weiwei, who was in charge of the rescue, wanted to say something, as if she had something new.

Under the guidance of Simon Chain, Li Weiwei finally spoke: "I can't guarantee that it's true...... When I went down with the rescue team, I heard a phantom sound. I asked the rest of the team at the time, and no one heard that sound anymore except me. It sounds like someone is speaking a foreign language, not English and French, and it doesn't sound like Russian and Latin......"

Li Weiwei's words made the eyes of Ximen Chain and the others light up, and under their questioning, the woman continued: "It seems that someone is lying on top of me, talking to my ear. I couldn't tell if it was a man or a woman, but it just said one sentence over and over again......"

Afterwards, Li Weiwei told Sun Desheng and them what she heard, but women still can't learn the tone that seems to be speaking and singing. Simon Chain asked, "It's just that you can hear such an illusion underground?" Can you still hear it when you come up? ”

"I can't hear it when I come up," the woman replied, and then she remembered something, and continued: "That voice is very urgent below, and the higher you go, the slower it becomes, and you can't hear anything when you come up." ”

"The later the night, the slower ......" Ximen Chain glanced at Xiong Wanyi, and then suddenly said a series of urgent and astringent words to Li Weiwei. Coupled with the frustration of his intonation, it really sounded like he was singing.

Li Weiwei's eyes lit up when she heard this, and she pointed to Ximen Chain and said, "That's it...... That's what I'm hearing below, you say different words, but the tone is the same. How do you know? ”

Without waiting for Simon Chain to answer, the squadron leader had already run over and said to the people in front of him: "It's almost, I can't smell the stench anymore." I didn't catch ...... when I lit the fire."

Xiong Wanyi nodded, he walked to the entrance of the cave, touched a piece of rune paper from his arms, lit it and threw it down. After standing on it and watching the rune paper slowly fall, he turned back to Ximen Chain and said, "It's clean, you can go down." Don't wait for those little cubs, the old rule is that the two of us will go down, and you and your brother will answer on it. ”
