I solved crimes in the Song Dynasty and strengthened the country [Seventh Five-Year]

53 The rain sinks into the golden house

It was office hours at the moment, Jiang Lin and the others packed up the evidence and went to the yamen.

On the way, Jiang Lin bought two small things to play with, and after a short delay, when they arrived at the gate of the yamen, Xu Zhizhou, who had been notified in advance, was already waiting for them.

Xu Zhizhou greeted and said: "Jiang Shaoqing and Fan Yushi, did you rest well at the station yesterday?"

Fan Chunren was scolded by Zhan Zhao last night, and his complexion has not recovered yet, as if he was still angry about getting up, and he ignored Xu Zhizhou at all.

Jiang Lin had no choice but to politely answer, and Xu Zhizhou asked again: "Jiang Shaoqing said yesterday that the person behind the case could be found today, and now he came to the Yamen early in the morning, but the matter has already begun?"

"Temporary secrecy." Jiang Lin smiled and did Tai Chi.

Although they were now suspecting Xu Zhizhou who had sent pigeons out of the mansion, they hadn't got any concrete evidence yet, so they couldn't act rashly for the time being, so Jiang Lin's attitude towards him was still very polite.

But Xu Zhizhou was obviously flustered: "Then Shaoqing came here for..."

"Jiang only went to the scene of the crime yesterday, and before he had time to see other evidence, he wanted to ask Xu Zhizhou to lead the way."

"Hey, look at this officer's memory. Of course it's okay." Xu Zhizhou waved at the yamen servant, and led Jiang Lin and his party to the backyard.

Xu Zhizhou ordered someone to take out all the physical evidence mentioned in the case file, and asked Jiang Lin and the others to read it again.

Most of the physical evidence was tattered box fragments, as well as some wreckage of the ship. Jiang Lin quickly focused on the only box that was not damaged but had no silver taels.

After the box was salvaged, the original seal attached to it had been removed, and it was left wide open in the courtyard.

Jiang Linli looked at the box for a while, and said, "Miss Yunshu, can you dig out some of the sand from the bottom of the box?"

Yun Shu understood what Jiang Lin meant, and took out some silt neatly, compared it with the silt in the bottle before, and then nodded to Jiang Lin.

The two of them seemed to be playing a charade, Bai Yutang couldn't help leaning forward and asked, "What's so special about this sand?"

Jiang Lin didn't answer his question directly, but asked: "Yesterday's incident has proved that the disappearance of military pay was caused by human beings, so what do you guys think about how the silver disappeared in the first place?"

This mode is basically the same as Jiang Lin's previous lecture method when he was reviewing the law exam. Bai Yutang answered subconsciously: "Isn't it because the box is broken and the military salary fell into the water?"

"Then how do you explain that the silver has disappeared from this intact box?" Jiang Lindao, "Not to mention that the weight of the silver itself is enough to sink to the bottom of the river, but no matter how hard the army searched, they couldn't salvage any of it. Find a way to explain the black mist Lao Lu saw."

Bai Yutang rubbed his chin, and thought seriously: "Actually, I thought about a possibility before, that is, the silver in the box was dropped in advance, and the box was already full of mud and sand, so once the box sank into the water, it would give birth to something. Any damage, the sand can hide in the water and disappear without a trace, and it can also explain the black fog that Lao Lu saw."

Xu Zhizhou on the side couldn't help but said: "Bai Sizhi's guess sounds quite reasonable. Why can't it be like this?"

"Because, according to He Military Academy's testimony, he had led someone to open the box to check the military pay before boarding the ship, and everyone present at the time saw with their own eyes that the money was neatly placed in the box." Jiang Lin looked at it. Xiang Xu Zhizhou showed a kind smile, "Isn't this what was recorded in the case file? Could it be that Xu Zhizhou... forgot?"

Xu Zhizhou was flustered immediately, and stammered, "I'm ashamed, I'm getting old, and I can't remember the case files that were approved in the previous ten days..."

Jiang Lin didn't bother with Xu Zhizhou's reaction, but continued: "However, Bai Sizhi's guess is not completely wrong... If someone uses a certain method to turn the sand into the shape of silver, wouldn't it be fine? ?”

"Is Shaoqing talking about the spell of 'turning stone into gold'?" Xie Ling asked in confusion, "No, if it really turns into silver, how can it turn back into sand?"

Jiang Lin didn't expect his thoughts to go so far, so he couldn't help laughing: "It's really like 'turning a stone into gold'. But this gold is fake. For example, we all know that children like to make clay figurines. How about making it in the shape of a silver block and then coating it with a layer of metal?"

Xie Ling suddenly understood.Jiang Lin looked at Yun Shu, and said, "But this is just Jiang's guess. Miss Yun Shu will tell you the specific details. First, let me tell you about the composition of the sand you found."

Yun Shu nodded and said, "Jiang Shaoqing ordered me to find out what the composition of the sand that made up yesterday's ghost image was, so I went to the morning market and asked some craftsmen. Contains a small amount of china clay, ordinary loess, and some special metal."

"The craftsman told me that if these three things are blended according to a specific ratio, compacted, and then air-dried... the specific steps are more complicated. In short, the made material can form a metal texture. strong structure, but becomes loose when exposed to water."

Jiang Lindao: "And the perpetrator only needs to add dyed cinnabar to this material, and then he can create the illusion that yesterday's ghost image dissolves in the water and disperses blood."

Bai Yutang came to his senses and said, "So you nodded after the comparison just now, because the sand left in the box is the same as that on that ghost!"

Zhan Zhao said: "In this way, according to what Jiang Shaoqing said before, as long as the surface is plated with a layer of silver-like metal, or even plated with real silver, it can be made into a silver ingot that is fake and can be dissolved in river water."

"It shouldn't be silver. Even if the perpetrator has other goals, the main thing is definitely for the silver, and he definitely doesn't want to pay for a batch of silver before he can get something done." Jiang Lin recalled his knowledge of chemistry, "The surface of the silver may be plated with a metal such as tin. White tin is very malleable, and its gloss is very close to silver, but it will become fragile and brittle gray tin when it is more than ten degrees below zero..."

Jiang Lin muttered for a while, and suddenly found that people around him were looking at him with incomprehensible eyes, he stopped talking quickly, coughed lightly and said: "I mean, gray tin has a strange characteristic, luster Bright white tin will be assimilated into brittle gray tin when it meets it, so although the two things are both tin, they must be kept separately..."

"And the perpetrator may have wrapped a small amount of gray tin in the middle of the soil and plated the outer layer with white tin. He Military Academy found no problem when he went to check, but it didn't take long for the gray tin to gradually corrode to the white tin. Then the box sank into the water, and the fake silver gradually dissipated and disappeared without a trace in the water."

"It turned out to be like this... No wonder the He Military Academy didn't see any flaws at that time..." Xie Ling said worriedly, "But who on earth would use such a method and be able to switch without anyone noticing?" silver?"

Jiang Lindao: "If the people behind the scenes want to make such a large amount of fake silver, they must have a considerable amount of white tin and gray tin, and have a suitable venue. Therefore, I suggest that Xu Zhizhou immediately send more people to strictly search Langzhou. In all the places where gray tin may appear, don't miss any detail."

As an imperial envoy, Jiang Lin could directly pass through Xu Zhizhou and urgently mobilize officials and servants in Langzhou.

But at this moment, he deliberately clicked on Xu Zhizhou himself, which immediately made the latter feel a little confused—is this person doubting himself, or believing in himself?

Xu Zhizhou swallowed, and said calmly: "Then besides this matter, what else can I do to help Shaoqing?"

Jiang Lin thought for a while, and said, "The two sunken boxes of black iron haven't been found yet. We plan to explore that area of ​​water again today, please ask Xu Zhizhou to prepare a better boat for us."

Before setting off to explore the secrets of the Black and White Pagoda, Jiang Lin planned to spend a little money in the local restaurant and get some news by the way.

None of them planned to reveal their identities, but Bai Yutang was a big celebrity in their Lujiazhuang area, and everyone in their eighties and three years old could recognize him.

Along the way, the bosses of various teahouses and restaurants saw Bai Yutang and wanted to greet him inside, even insisting on offering him a discount.

"Tsk, cat, look at how charming Fifth Master is." Bai Yutang's tail was almost up to the sky, and he led the four of them around, but he couldn't find a suitable tavern.

In the end, Fan Chunren, who had studied for more than ten years, was defeated because of lack of physical strength.

He didn't particularly want to have dinner with Jiang Lin and the others, but he was willing to take two extra steps with Jiang Lin because he wanted to participate in the afternoon's action.But after realizing that he was not welcomed, Fan Chunren didn't have the idea of ​​making himself boring.

Bai Yutang glanced at his leaving back, and then boldly said that he would treat the other three to the most expensive restaurant.

Zhan Zhao is not a person who sticks to small details, and he has not divided himself with Bai Yutang.Jiang Lin also adhered to the principle of "If you have the advantage, don't take advantage of the bastard", and cheekily rubbed it up, only the panting Xie Ling said: "Bai Sizhi should treat the lower officials to dinner, if I accompany you 'martial arts' again Go down, I'm afraid I won't be able to return to Kaifeng Mansion."

Everyone laughed and entered the restaurant, Jiang Lin caught a passerby who seemed to be good at gossiping, and took the other three to sit down next to him.

"Did you see it just now? An official came out of the yamen and sent a letter to the army. Is the loss of military pay settled?"

"Isn't it? I heard that the imperial envoys who came this time are not young. It seems that even the royal cats appointed by the emperor are here! I don't know if those masters of the Lu family will come to find someone else..."

Bai Yutang kicked Zhan Zhao under the table, which drew a helpless look from the latter.

The next table turned the topic back to the case: "But let me tell you, this black and white tower is quite evil. Isn't it the first time a boat was lost there? The old Li Tou and his son passed through the hole the other day. , it hasn't come out yet!"

"Yes, yes, my brother always likes to run into the Songjiang River. Once he said that he found an interesting cave in the Black and White Pagoda, and he carved a mark on the stone wall. When he goes to see it another day, then The mark on the stone has completely disappeared without a trace! You say it’s scary!”

After hearing this, Jiang Lin suddenly had a bold guess about the disappearance of the cargo ship.
