Tonight is the first time this book has hit the list.,Because I don't want things other than the text to affect everyone's reading.,So since the book was opened, there are few serious votes.,It's all at the end of the shouting weakly.。 Now it seems that the shouting is the same as not shouting.

I believe you all know how important it is to a new book, so please come and have a show if you haven't slept at 12 o'clock at night. Of course, as always, there will be an outbreak and a change, and I hope everyone can put me on top.

・・

Zhang Tongxun didn't talk nonsense, gave a brief introduction to the situation after Liu Kai came, and also told Shi Lei a few questions and the suspicions he raised.

"Lao Shi, this kid of yours is much stronger than the unfinished thing in my family, if he hadn't reminded us, we would have ignored this matter and should start with Bibo Building." The explosion occurred before the collapse, and I've basically confirmed that. Whether there is a problem in the project, or there is something else hidden, it seems that Liu Kai already knows about it. He can know that someone must have reported to him, so those engineers of Bibo Construction must know something. ”

Hearing this, Shi Weixian couldn't help but nodded, but glanced at Shi Lei with some suspicion, and finally said: "Chen Gong has always been with me, he is in charge of the preliminary survey, I want to see if there are other possible places to escape in the air-raid shelter." After so long, the soil layer at the entrance of the air-raid shelter is still very thick, and now the situation inside is relatively clear, two seriously injured, three lightly injured, even if we dig through the hole, the two seriously injured may not be able to hold out until that time. But I don't see anything suspicious in him. ”

"Dad, you're not engaged in criminal investigation, and besides, you only think about saving people, how can you pay attention to what is abnormal about that engineer?"

Shi Weixian thought about it, and seemed to feel that what Shi Lei said was reasonable: "Then I'll call Chen Gong over, and Lao Zhang, you will have a good trial." ”

Zhang Tongxun said: "It's just a routine inquiry. ”

Shi Lei said again: "It's better to go over and ask, Liu Kai is also beside him, I can't see something more from the interaction between them." ”

"What advice do you give, what do you know?" Shi Weixian became more and more severe.

Zhang Tongxun patted Shi Weixian's shoulder: "I think what Shi Lei said is very good, unexpectedly, I asked in front of Liu Kai, I can't really see something more from Liu Kai." ”

Seeing that Zhang Tongxun also said this, Shi Weixian couldn't say anything, so he had to nod: "Don't think that if you take the first place in the school, it's over, the university is your starting point." ”

Shi Lei stuck out his tongue, smiled, and didn't say much, and the three of them walked towards Liu Kai and Chen Gong together.

At this time, there was already a policeman by Liu Kai's side, who was paying close attention to the communication between him and Chen Gong. Shi Lei also knows that even if there is really something hidden, these two people will not say it now, but they don't know how long this policeman has been here, and whether there is anger between Liu Kai and Chen Gong.

"Chen Gong, Director Zhang has something I want to ask you." Shi Weixian beckoned to the man who was about fifty years old next to Liu Kai.

Shi Lei has been staring at Liu Kai, and when Shi Weixian said that Zhang Tongxun wanted to talk to Chen Gong, he obviously showed a little anxiety.

It's that Chen Gong, Shi Lei didn't see anything wrong with him. But Shi Lei firmly believes that as an engineer in charge of preliminary surveys, if he doesn't even know that there is a septic tank more than ten years ago underground, this engineer can be laid off directly.

"Director Zhang, what else do you have?" Chen Gong pushed the glasses on the bridge of his nose.

Zhang Tongxun stepped forward and shook hands with him first, but unexpectedly, he did not speak, but turned his eyes to Shi Lei.

Shi Lei didn't want to participate in the questioning, but he just wanted to observe from the sidelines, and if he found something wrong, it would be the right interjection. But now Zhang Tongxun obviously wants him to ask, and Shi Lei can only ask stubbornly: "Chen Gong, now it has been confirmed that the number of dead is three, and there are more than a dozen seriously injured people in the rescue." According to the hospital, at least four of them are likely to spend the rest of their lives in wheelchairs, and two of the others are still in a coma and do not know when they will wake up. There were five more people in the dugout, at least five more from what we have now, maybe more. Two of them were seriously injured, one with a broken leg and the other with a broken sternum and both are currently bleeding profusely. You know all of this......"

Chen Gong looked at the extremely calm young man in front of him, although he felt that it was a bit ridiculous for him to ask, but Zhang Tongxun was obviously very supportive, although Shi Weixian wanted to stop him, but Zhang Tongxun blocked him in time. Chen Gong had to reconsider the purpose of Shi Lei's questioning.

Nodding, a little arrogant, Shi Lei judged this person to be extremely confident in his profession, and even conceited.

"I know a little bit about this, but I don't know you in detail. Xiaoshi, what exactly do you want to ask? ”

"These losses have been done, and in any case they are human tragedy, and the most important thing for us now is to get the people inside, but we must also be clear about the cause of the accident. And Director Zhang and I just now both smelled gas nearby - oh, to put it more technically, it should be the smell of petroleum gas, and we also learned that there had been an explosion before the mountain collapsed. I don't know if the landslide was caused by the explosion, but I would like to ask you if you know exactly what caused the explosion. I asked Mr. Liu just now, and he said that the welding torches used in your construction are all fueled with high-purity acetylene, which is a tasteless gas, so the fuel leakage of the welding torch can be ruled out. ”

Shi Lei stared at Chen Gong's eyes, pressing step by step, hoping that he could identify whether this Chen Gong's upcoming answer was a lie.

Chen Gong shook his head slightly dazedly: "Does it smell of liquefied petroleum gas?" How I didn't smell it. I don't know the cause of the explosion, but I'm pretty sure it couldn't have been an engineering problem. After hearing the news of the explosion just now, I asked someone to check our acetylene gas tanks, and all the gas tanks were there, and there should have been no welders working at that time. ”

Shi Lei couldn't see anything wrong with this Chen Gong, it seemed that he really didn't know the cause of the explosion.

In the short period of time just now, Shi Lei had already thought of many ways to poke out the septic tank thing as untraceable as possible, and now, he had to make a decision.

"Chen Gong, you're in charge of the preliminary survey, right? I'm interested in architecture, and I like to read books on it. As far as I know, the preliminary survey of the building is not only the surface part, but also the underground part, right? ”

Chen Gong nodded with a little surprise, and lifted his glasses again: "You are talking about conventional survey, our project has a certain special surname, and more surveys end point in the mountains above the air-raid shelter, and the facilities that are renovated and added will not cause too much pressure on the ground, so there is no need to do a detailed survey below the ground." ”

"You don't need to do a detailed survey, so do you still need to survey? I would like to know, as the person in charge of the preliminary survey, have you found any hidden dangers that are not suitable for large-scale renovation? ”

Chen Gong frowned, Shi Lei looked more and more aggressive, he didn't like such a sharp young man. However, Shi Lei was standing behind the director of the Municipal Public Security Bureau, especially the father of the deputy mayor, and he couldn't help but have the temper of an intellectual.

"The heavy rainfall in the previous period loosened the surface of the mountain, and I have long suggested that it may cause a landslide. So before the start of the project, we actually did some mountain earthwork reinforcement work. I also asked some construction workers about the explosion, and they all said that the shaking was not too big, and it should not be the main cause of the collapse. Petroleum gas...... LPG ......" The old engineer was obviously thinking carefully, and suddenly his expression froze, and the whole person seemed to be stunned, "It can't be because of that septic tank, right?" ”

Shi Lei's heart finally let go, no matter what, the septic tank is ready to come out. The next thing he could do was to step aside.

"Septic tank? What a septic tank! Shi Weixian and Zhang Tongxun glanced at each other and said at the same time.

Chen Gong was slightly distracted, and Liu Kai beside him was already pale.

"The place where we are standing, about 20 meters to the north, was originally a septic tank of considerable size, which was mainly responsible for the sewage discharge and purification of nearby residents. The septic tank was discontinued in '84 and then covered and filled, 13 years ago. I raised this question during the initial survey and submitted it to the quality supervision department for inspection. Since the quality supervision department has not raised any quality hazards for this septic tank, I think there should be no problems, right? ”

Shi Weixian's eyes lit up, and he immediately said to Liu Kai: "Mr. Liu, do you know about this matter?" Did you know that there was a septic tank in the area that was discontinued more than 10 years ago? ”

There is no need for Liu Kai to answer Shi Lei also knows that he will not admit it, if he does not admit it, at most it is the negligence of the engineering quality supervision department, and the responsibility cannot be held accountable for him, let alone implicated in the people behind him. But Liu Kai's performance has already made Shi Lei quite frightened, he must have known, and even he hid this hidden danger and did not report it. Knowing that there is such a big hidden danger, but not caring about it, this is not just as simple as careless human life. Shi Lei felt a hint of anger from his emotions.

"I really don't know about this, is there a septic tank around here?" Liu Kai spoke, but his eyes unconsciously looked towards the location of the septic tank.
