Chapter 608 Sulfuric Acid
"Are you going to come back and meet Li Meng?" Yan Yu asked, "How many days are left for your training?"

"Training is still early, there are still ten days left, and the training in the next few days is interesting, and there are practical classes," Lu Ling said, "Why did you see Li Meng? Shouldn't you ask Li Yuan for this matter?"

"For Li Yuan's side, Qingshan and I will look for it soon, you don't need to worry about it. Although she is in Liao Province, she is closer to us than you." Yan Yu said, "In this situation, don't you think Li Meng has Is there a problem? He didn't tell us about the half of the clock mark that Li Meng lost when he went into the water."

"Boss," Lu Ling said, "I know you always think Li Meng is weird, but Li Meng is really fine. He just has a problem with his growth experience, so that his personality is a little flawed, even extreme, but he is really fine. Have you ever thought about what will happen to Li Meng if we don't show up? He will definitely kill himself."

"I know," Yan Yu said, "this is not contradictory. He may indeed be a great policeman, but it depends on what to face. I have seen many people, he can ignore his own selfishness when the people are in danger. Life, but can also be extremely selfish on family issues, this is not contradictory."

"You mean, he may violate the principle for the sake of his father?" Lu Ling paused, "Trust me, he won't."

"We are looking for Li Yuan today. I don't know what kind of situation we will encounter. Maybe we found Li Yuan's problem directly and took Li Yuan away. It is also possible that Li Yuan said that she was adopted by her father back then. , or Li Yuan said that she was a child brought by her mother, etc. In short, if Li Yuan has a reason prepared in advance, we can’t summon Li Yuan before we find out. We don’t even have any reason. Therefore, , Maybe today’s investigation came back in vain, once we leave, if Li Yuan and Li Meng are related, if they communicate again, our follow-up work will be very passive.” Yan Yu explained.

"Then what should I do better?" Although Lu Ling trusted Li Meng, he knew that from the perspective of handling the case, the captain was right.

"Look for Li Meng again."

"How to find it?"

"You decide for yourself, if you think video is okay, then video."

"Okay." Lu Ling said, "Thank you."

"Thank you, I believe you, not him."

"Hey, good." Lu Ling hung up the phone with satisfaction, and then immediately called Li Meng.

After lunch, Lu Ling returned to the dormitory, and then started playing VR games. Today, he played a shooting game, but Lu Ling was unlucky. After entering, he never picked up a gun. He took something like a crowbar in his hand. , facing the enemy can only choose to hide and hit the sap.

Lu Ling used the handle to control the character to move forward, slowly hid under a dark staircase, and then squatted down. At this time, someone happened to go down the stairs.The sound channel of this game is not bad, allowing users to hear the direction of the sound through the binaural effect. Lu Ling felt that the sound was getting closer, so he prepared his weapon and prepared to attack the enemy.

Just when the enemy was about to appear, Lu Ling's cell phone rang, which confused his thinking, and he picked up the crowbar and smashed it down.After making the shot, I realized that I had hit the wrong person. The opponent was not an enemy, but an NPC in this game, a housekeeper.

The game doesn't have a real setting like "smash your head", but it does happen that your head turns red and you fall to the ground, and your face looks a little aggrieved.Of course, the setting of this NPC has no expression, and the grievance is fake, but at this moment, Lu Ling, as the attacker, made up the state of "grievance".For a moment, Lu Ling felt a little sorry for the maid, and suddenly felt guilty, so he could only pause the game and answer the phone.

"Zhou Suo?" Lu Ling asked, "What's wrong?"

"Captain Lu, didn't you ask me to check on this suitcase?" Zhou Xinxin said, "Master Qu and I have visited in the past few days, and also contacted the uncle Lei you introduced. This morning, Master Qu and I were near the entrance of the village. I met a villager who came back to the village after fishing. After chatting, he told me that he saw a villager come back with a heavy suitcase a few days ago. The person who carried the suitcase was Wang Nanhang, and then we went to I checked Wang Nanhang and found that this person is related to Wang Cheng, a distant relative. Then we went to his house and found the suitcase we were looking for, but there was nothing in it, and we didn't find any other obvious things. I asked him where he got the material, and he said he picked up the box outside. Now, I have brought back Wang Nanhang and the suitcase. I can only take a general look at their house, without a search warrant, I can’t thoroughly Search. Master Qu is watching at his house now, I went back to the police station this time and left Wang Nanhang outside to find someone to watch, so I can call you conveniently."

"Did the fishing friend see it?" Lu Ling said, "The fishing friend said it was heavy, right?"

"Well, that's how he said it looks heavy, and it's hard to lift."

"Okay, I'll go there right away." Lu Ling immediately told the leader, and drove the car here to the Suying Town Police Station.

When he arrived at the police station, Lu Ling went directly to the mediation room next to him and saw Wang Ping and Wang Nanhang.

"Team Lu!" Wang Ping hadn't seen Lu Ling for a few days. As soon as he saw Lu Ling, he trotted over, touched his left pocket, then took out a box of Zhonghua from his right pocket, and pulled out one. Handed it to Lu Ling, "Long time no see, Captain Lu, you are finally free to come back and guide the work."

"It seems to be doing well recently," Lu Ling waved his hand, "I don't know how to smoke, so come by yourself."

"Okay," Wang Ping didn't light a cigarette for himself, but put the cigarette back into the cigarette case, and then put the cigarette back in his pocket.

Lu Ling's energy was mainly on Wang Nanhang.Wang Nanhang didn't look like Wang Cheng at all, so he might be a little distantly related. Lu Ling took out a photo from his mobile phone last week and asked directly, "Are you Wang Nanhang? I'm from the provincial government. I'm here to find you." Understand the case, this box, you said, you picked it up?"

"Yeah. I picked it up." Seeing Lu Ling, Wang Nanhang was a little scared for some reason.

Before coming here, Lu Ling knew about the situation of the box.From the perspective of size, it is a 51*30*14cm lockbox, with a space of 16-18 liters. The box itself is not heavy. If it is filled with water, the box will weigh more than 30 kilograms.According to Ma Sizhen, the box weighs at least 50 kilograms, and it is relatively full, and it may contain liquid.

Of course, it can't be all mercury. If it's all mercury, then the weight will take off. Let alone Ma Sizhen can't hold it, Qingshan is struggling.Lu Ling judged that there should be 2-3 liters of mercury in the bottle, surrounded by a large amount of sponge.

"Are you still talking about this?" Lu Ling looked at Wang Nanhang, "You think about it here, and I will come to you in a while. Now I will give you 20 minutes to confess. You are not an important person, so don't be bullied. out of prison!"

After speaking, Lu Ling greeted Wang Ping and went to find Zhou Xinxin.

Zhou Xinxin is currently studying the situation of this box. Besides him, there is also a policeman wearing gloves, who is also studying this box.

"Why does this one look familiar?" Lu Ling asked.

"The nobles of the Lu team are forgetful," the person who spoke was surnamed Yang, "I am a member of the guerrilla team. My surname is Yang. I am doing on-site investigation. Zhou Suo specially found the guerrilla team, and the guerrilla team sent me here. You are from the city. It’s just a little bit later, we’ve been studying it for a while.”

"Oh, oh," Lu Ling nodded, "Brother Yang, I'm sorry, is there any general reasoning for this?"

"There shouldn't be any mercury in this," said Police Officer Yang. "The proportion of mercury is too high. It's fine if it's a professional bottle, but if it's bottled with ordinary mineral water, each bottle weighs more than ten catties." Heavy, even if it is cushioned with a sponge, it will run around in this box. This aluminum alloy box is actually very thin, and a few bottles of mercury can be shaken a few times to cause a certain deformation of the box, but in fact it does not. From the carrying Judging from the use of the hand, it is indeed loaded with heavy objects, and the handle has been damaged to some extent. Moreover, this box should have been used once."

"That thing uses dozens of professional small bottles to encapsulate mercury?" Lu Ling asked again.

"It's mainly here," Officer Yang pointed to a cotton swab, "Look, Captain Lu, there are a few places on the inner wall of this box, a little bit of white powder appeared, and according to Zhou, he just When I first saw the box, it wasn't there yet."

"what is this?"

"I haven't tested it yet, so I have to take it back for testing to be sure. At present, according to my analysis, it should be aluminum sulfate," Officer Yang said. "Since it is mentioned that this box is relatively heavy and it may be liquid, the range is actually very small. The specific gravity The big liquid is too little, except for bromine, only concentrated sulfuric acid and mercury are left. Not to mention mercury, two or three liters weighs sixty to seventy catties, and the specific gravity of concentrated sulfuric acid is 1.8. If this box is full, there will be It weighs 60 jin. Concentrated sulfuric acid and aluminum will undergo a passivation reaction. Simply put, a protective film will be formed and the reaction will stop. However, Zhou Suo opened the box, and the concentrated sulfuric acid will absorb the air in the open environment. Water forms dilute sulfuric acid, which can react with aluminum to form white aluminum sulfate, so I suspect that there was a whole box of concentrated sulfuric acid in it."

"I agree with your statement." Lu Ling's high school chemistry is not bad. Although most of them are returned to the teacher, he thinks that there is nothing wrong with Officer Yang's theory. "In this case, we can actually check it easily. I am quite familiar with it, and there should not be many places where concentrated sulfuric acid can be obtained.”

"Well," Zhou Xinxin said, "I've checked, and there's one place that's easy, and that's a lead-acid battery factory, where a lot of concentrated sulfuric acid is used. Moreover, Zhang Jinxiu, whom you told me before, is there now. work nearby."

"Sure," Lu Ling said, "Zhou Suo, your investigative thinking is meticulous enough, and you got to this point so quickly."

"What's the matter?"

"Then, Zhou Suo, what do you think should be the next step?"

"It's relatively simple. Wait for the test. If the powder is indeed aluminum sulfate, then we can probably tell it's sulfuric acid. I discussed it with Brother Yang just now. Sulfuric acid has many functions, and it's hard to determine what Wang Yiwen uses it for."

"Can it be used to refine gold?" Lu Ling asked.

"Of course," Police Officer Yang took over, "Concentrated sulfuric acid can be made into dilute sulfuric acid. Dilute sulfuric acid is one of the materials for purifying gold. Besides, sulfuric acid can be easily prepared into hydrochloric acid, and hydrochloric acid has a wider range of uses." , in short, it is unrealistic to speculate on the equation. These things can even be used to make explosives."

"Can it make poison?"

"Yes." Officer Yang gave an affirmative answer.

This is troublesome. Sulfuric acid is so versatile that it is impossible to guess.

"The next step is to start the investigation from the battery factory," Zhou Xinxin said. "We will definitely be able to find out who secretly released dozens of liters of sulfuric acid. Of course, it may not necessarily be from the battery factory."

"There is no way to file a case on this matter, so I can only trouble you to investigate first." Lu Ling looked a little cautious, "I really don't understand what this Wang Yiwen wants to do now."

"Didn't you say before that she wanted to make gold? Besides, mercury beads were also found in that village?" Zhou Xinxin asked.

"The current situation is indeed more complicated," Lu Lingdao, "Let's investigate first. If it is confirmed that it is sulfuric acid, we will continue to investigate."

"Okay, then I'll take samples, I'll go back first." Officer Yang said.

"Okay, I'll meet Wang Nanhang again," Lu Ling said.

After bidding farewell to Zhou Xinxin and Zhou Xinxin, Lu Ling returned to the courtyard of the police station, looked at his phone, and found an unread WeChat message. It was Li Meng's.

"I'm almost there, where can I find you?" Li Meng said.

"Come to the Criminal Investigation Brigade of Dong'an County Public Security Bureau. I'll be there later." Lu Ling replied.

"Okay, I'll take a taxi by myself." Li Meng replied.

This morning, Li Meng received a call from Lu Ling.On the phone, Lu Ling didn't say anything to Li Meng. He just asked Li Meng to come to Liaodong City and had something to say to Li Meng.

Lu Ling calculated the time. After Li Meng got off the car, he took a taxi and estimated that he would be there in an hour. In this way, the time for him to ask Wang Nanhang was relatively short, and he had to make a quick decision.

When he arrived at the mediation room, Wang Nanhang was still sitting there, a little timid.

Wang Ping crossed his legs, holding a box of Hongtashan in his hand, and was smoking.

"Captain Lu," Wang Ping immediately stood up.

"It's okay," Lu Ling said, "Call this person into the case handling area."

"Okay," Wang Ping walked to Wang Nanhang's side in two steps, knocked on the table vigorously, and shouted, "Get up! Come with us!"

Wang Nanhang was taken aback. He glanced at Wang Ping and then at Lu Ling. He still felt that Lu Ling was more terrifying, so he leaned on the back of his chair and stood up tremblingly. With Wang Ping's support, he followed the two of them. Entered the case handling area.
