I Opened the Door of Hell in the Town Night Division

　　 "And this mysterious liquid is called aqua regia."

　　 This Zuo Ye really deserves to be a genius alchemist, he actually matched Wang Shui?

　　Also, aqua regia is extremely unstable. It must be prepared for immediate use. In the process of melting, it still releases a large amount of toxic chlorine gas.

　　 At this time, not only Lin Guanghan was surprised, but Yin Taishou was also full of incredible.

　　 There is such a magical liquid in this world? Can directly dissolve gold?

　　 Zhang Zhaozhong said: "Such a magical liquid can dissolve gold, why can't it dissolve silver?"

Duan Yu said: "This kind of aqua regia can melt gold, in fact, it can also dissolve silver. It's just that when the silver is first dissolved, a protective film will be formed on the surface of the silver. Therefore, all the silver in the entire silver vault looks safe and sound. Part of it has actually been dissolved. And after you opened the vault and came in, didn't you smell a smell?"

　　 Lin Guanghan said: "Vaguely, very light."

　　 Duan Yu closed his eyes and was amazed.

　　 This is really a terrible robbery.

　　 Zuo Ye is really a genius alchemist, and he came up with such an incredible method and stole one hundred thousand taels of gold.

　　 The people from Zuo Ye are on the river, and they use a special barrel to add the gold solution and transport it back to extract the gold.

　　 But why didn't Zuano use mercury? That would not only dissolve the gold, but also dissolve and steal the silver.

　　 But Duan Yu soon knew why.

　　Because once mercury is used, the entire silver vault scene will be destroyed, unable to create a sense of mystery without knowing it.

　　 It seems that Zuo Ye is still a perfect criminalist.

　　 Lin Guanghan said: "Duan Yu, this statement of yours is too unbelievable, I can't report to it, I need evidence. Otherwise, we will report this and we will not be guilty of crime."

　　 Duan Yu said, "Do you have strong acid in your town, Ye Si?"

　　 Lin Guanghan said, "Yes, we have all kinds of strong acids, some from volcanic pools, and some from poisonous snakes' stomachs."

　　 Duan Yu said: "You immediately send someone to find all the strong acid, and I will do an experiment to show you."

　　…………

　　 More than half an hour later, various strong acids were placed in front of Duan Yu.

　　 is really awesome, I have never seen some strong acid Duan Yu.

　　 Fortunately, the world has produced gunpowder a long time ago, so there is no shortage of nitrate, otherwise it would be difficult to produce nitric acid.

　　 Duan Yu made nitric acid and then made sulfuric acid.

　　 Next, start to configure two strong acid concentrations. If it is too strong, it will become thinner.

　　 If it is too thin, try to make it thicker.

　　 In the end, a 1:3 ratio was used to make aqua regia with nitric acid and hydrochloric acid.

　　 Even though he was protected, he was still cautious.

　　 was not very successful the first time, not perfect the second time, and perfect the third time.

　　 The aqua regia was successfully configured, and it began to volatilize chlorine, which is really deadly.

　　 Duan Yu said to several big bosses: "Everyone, take care of yourself and keep your eyes open."

　　 Then, he directly threw a piece of gold into the aqua regia.

　　 The reaction was not very intense at first, but after heating the aqua regia, the reaction became very intense.

　　 This piece of gold melted away almost at a speed visible to the naked eye.

　　 After a short while, this piece of gold disappeared without a trace, completely dissolved in the aqua regia.

　　 Yin Tianen, Lin Guanghan and others were amazed and couldn't believe what they were looking at.

　　 Duan Yu, a brothel mate, really broke the mystery of the disappearance of gold.

　　 is really incredible.

　　 It was a coincidence that Yin Mochou's death was solved before.

　　 And today's cracking of the gold theft case can only prove that Duan Yu is a genius.

　　 Several adults looked at Duan Yu's eyes, and they all changed in an instant.

　　……

　　 But... Duan Yu still has two mysteries that I can't figure out.

　　 First, the aqua regia dissolves gold, which will definitely leave mottled marks.

　　 Why is the scene so smooth and clean without leaving any obvious traces?

　　Secondly, it is even more incredible.

　　 Yinku is more than a hundred meters away from the river. How can a passage be dug in a short time?

　　 And this passage is so narrow, only about five centimeters in diameter, obviously it was not dug out by manpower.

　　 These two mysteries are really puzzling!

　　 And this gold stealing scheme sounds simple, but it is very difficult to operate.

　　 Need to configure a lot of aqua regia, not to mention, but also to make a long and special pipe that can withstand the corrosion of strong acid, only in this way can the aqua regia be poured into the silver vault to dissolve the gold into water.

　　…………

　　 Taishou Yin Tianen said: "Because of Duan Yu's contribution, the mystery of the disappearance of gold has been solved."

　　 Lin Guanghan said: "Not only that, but now it is also certain that this genius female alchemist Zuo Ye does exist, and she is very likely to be the real murderer of Yin Mochou and the person behind the stealing of gold."

　　 Yin Tianen said: "Now there are two questions. Zuo Ye stole one hundred thousand taels of gold for what? The second question, where is she? Where is the gold? We only have one day!"

　　 At this time, it is not enough to solve the mystery of the disappearance of gold, but also to catch Zuo Ye and find the lost one hundred thousand taels of gold.

　　 Duan Yu asked: "In the past few days, the three adults took turns guarding outside the silver vault. When the aqua regia dissolves the gold, a violent reaction occurs. There is a sound and a peculiar smell. Didn't you notice it?"

　　 Lin Guanghan said: "Let's do an experiment, and you will know."

　　 Next, the three of them left a strong man in the silver vault, and then slowly closed the gate.

　　 The brawny man hissed inside.

　　 "Ah...ah...ah..."

　　 He kept roaring.

　　 But after the gate of the silver vault was completely closed, it turned out that there was no sound at all.

There is no way, this silver vault is too tightly protected, and the one-foot-thick iron door is also wrapped with wooden boards. In order to be completely airtight, the door is wrapped with special materials without leaving the seam. It is really impossible to hear a little sound. .

　　 In this way, I don’t know exactly when the gold was stolen.

　　…………

　　 In the secret room, Duan Yu and four adults are having a meeting.

　　 "Four adults, how about I make a bold inference first?" Duan Yudao.

　　 Yin Tianen said: "Please speak."

Duan Yudao: "Zuo Ye and others must be on the river. They injected an astonishing amount of aqua regia into the silver bank through a special pipeline. It took a long time to turn the yellow money into water, and then the golden water was drained out through a special pipeline. "

"In this way, she needs a ship, which must be tall enough. Only a tall ship can create a height difference, and the configured aqua regia can be injected into the silver vault through a special pipeline. So this ship The height of the anchor on the river must exceed the height of the silver bank.

　　 "I have roughly calculated that the height of this ship must be at least 6 feet high. This is not an ordinary ship, but a tall ship."

"And this ship must be moving in the middle of the night, and it will have to stay for a long time. If I am not mistaken, the night of the operation should be heavy rain. Only in this way can the trace and sound be hidden. In the recent rainy season, it rained very much in the middle of the night. frequently."

　　 "If my guess is reasonable, then we only need to find a tall ship. In the three days since the gold was lost, there must be very few tall ships passing through this river."

　　 "As long as you find this ship, you can find the whereabouts of the gold, and UU reading www.uukānshu.com can also find the trace of Zuo Ye."

　　 "Four adults, is my guess reasonable?" Duan Yu finally said.

　　 Yin Tianen nodded and said: "It is very reasonable. If your inference comes true, then we are not looking for a needle in a haystack, and the suspected target is suddenly reduced to a certain range."

　　 Lin Guanghan said: "If there is such a ship, it is not difficult to find it."

Duan Yudao: "Several adults, now we have an advantage, that is, the enemy does not know that we already know the mystery of the theft of gold, nor do we know that we have locked the suspect target on the boat on the river. It's also dark."

　　 Several adults nodded.

　　 Duan Yudao: "So, on the surface, we still have to search the whole city, digging three feet. But in the dark, we must focus on investigating all the boats passing by this river in the past few days, and play a real Mingxiu plank road dark Chencang!"

　　 Taishou Yin Tianen said: "Just follow Duan Yu's plan. We only have one day. We must find this 100,000 gold, and we must catch Zuo Ye, the unpredictable genius alchemist."

　　 Lin Guanghan said: "It's not difficult to find this boat, because all entrances and exits of this river have cash gates. As long as there is a boat going in and out, there will be records."

　　 Then, he looked at Duan Yu and said, "Once you catch this Zuo Ye and find the stolen gold, Duan Yu has done a great job, and I will definitely give you a reward."

　　 "Masters, we will act now and go all out!"

　　 "There is only one day to find gold and capture Zuo Ye."

　　 "Take out all the forces, capture Zuo Ye, uncover the truth, and set off!"
