"Tian Gen?" Bai Song was walking on the street when he received a call from Director He. Tian Gen went to the village branch to look for him, and only wanted to see Bai Song, not anyone else.
"Well, he said he believes you." Director He's tone was somewhat helpless. Tian Gen was a stubborn kid.
"Okay, I'll go over there." Bai Song nodded. He didn't expect to get any useful information from Tian Gen, but this matter was caused by Tian Gen, who was also a good boy.
…
Tian Gen felt that the house full of police officers seemed more familiar to him than his own home. When he saw Bai Song, his eyes lit up.
"Uncle...can I...can I go with you?" Tian Gen said.
"Why? Do you also think your sister went to Shangjing?" Bai Song reached out and touched Tian Gen's head.
"I...I also think my mother is abnormal." Tiangeng said somewhat uncertainly.
"What do you mean?" Bai Song asked, "Is your mother suddenly rich?"
As to whether Tian's mother sold Tian Fang, everyone had investigated carefully, including checking whether Tian's mother had received any unexpected wealth recently, but nothing was found.
"Money?" Tian Gen was a little confused: "Did my mother also go to provide you with clues and get paid?"
"That's not the case." Bai Song shook his head. "Go on, tell me what's wrong with her."
"She...she doesn't rest well every night and keeps chattering away," Tian Gen said a little embarrassedly after looking around.
Bai Song dismissed everyone, leaving only him and Tian Gen in the room.
"She... said something at night... dedication... dedicating herself or something..." Tian Gen felt a little embarrassed.
"This?" Bai Song felt like he was hit on the head after hearing Tian Gen's unclear words!
After hearing this, Bai Song immediately understood what was going on!
evil!
teach!
!!!!
Bai Song patted his forehead!
It turned out to be this form of crime. No wonder all the previous feelings were weird!
If that's the case, then everything makes sense!
This thing can destroy a person's family and cause their death, and people still believe it to be true.
Bai Song called out and asked two local policemen to come in: "Look after Tian Gen and take good care of him."
After saying that, Bai Song led the team directly to Tian's mother's house.
Bai Song went there with a lot of fanfare this time. Not only their people went with him, but more than a dozen people from Director He also followed.
For safety reasons, everyone went into the yard. In fact, it was not unsafe, but everyone was worried about Bai Song coming in by himself, as if this was some kind of dangerous place.
Bai Song had been to Tian Gen's home before, and clearly remembered that Tian's mother had a place to burn incense at the door of the house. Tian Gen's family was very poor, and except for the three tiled houses, there was no other place to shelter from the wind and rain.
I had seen this place before, but no one took a close look.
"Police! Don't touch this!" Tian's mother hurried over to stop Bai Song because Bai Song picked up an incense burner.
"What is this?" Bai Song asked.
"Nothing." Tian's mother stepped back.
Bai Song was a little confused. There was nothing wrong with the incense burner, but the ash inside seemed a little special. He pinched the ash with his hands, and it didn't feel like ash, but very heavy.
"What is this?" Bai Song asked.
The woman looked at Bai Song with some horror, as if Bai Song was about to be infected with some misfortune. She said nothing and took two steps back.
"Metallic texture." Wang Huadong also pinched a little. "It has a very high specific gravity. It feels almost like iron."
"Tin." Bai Song looked at it carefully and said, "I understand what's going on. It's a scam."
"The tin in tinfoil? Isn't that silver? Not this grey metal powder?" Huadong was a little confused.
At this moment, Bai Song seemed to understand what was going on.
In the past, in some places, people would use metallic sodium to play tricks. For example, when performing a trick to show people that there was a ghost in the water, they would secretly hide a small piece of metallic sodium in their sleeves, and then throw it into the basin of water when "catching the ghost".
We learned about this chemical reaction in high school chemistry. An explosion will occur. The metallic sodium will "swim" quickly on the water surface, generating sodium hydroxide and hydrogen. The explosion will also form white mist.
With the popularization of compulsory education, such scams are becoming less and less popular now that there are people who have attended high school in every village.
When Bai Song saw the metal tin, he instantly understood what the routine was.
"Metallic gray tin," Bai Song said, "This is a process of allotropy change, which is scary. Under normal pressure, tin has two allotropes, white tin and gray tin. We usually use white tin, which is metallic. But this metal is very special. When the temperature drops below minus 13.2 degrees, it may be converted into powdered gray tin. Gray tin has a diamond-shaped crystal structure, and the atoms are covalently structured. Electrons cannot transfer freely, so it loses its metallic properties and becomes powder. This process is called tin epidemic, which is infectious. After white tin and gray tin come into contact, white tin will gradually turn into gray tin, and its density will drop by about 20%. I think those bad guys may have told this woman that under the influence of some kind of divine power, silver will turn into powder or something."
A group of people looked at Bai Song and said, all of them were confused and came to see what this thing was. Not to mention seeing it, they had never even heard of it!
"There is such a thing?" Sun Jie asked, "Why haven't you learned this before?" "It's only -13 degrees Celsius, why is tinfoil in our daily life okay?"
"The tin in our daily life contains impurities such as aluminum and zinc. It may also contain antimony and bismuth to increase ductility and lower the critical temperature of tin disease," Bai Song said. "And the conversion rate is not that high. It is safer to convert it into gray tin below minus 20 degrees. This place, outdoors, can indeed achieve this. If the tin block provided is relatively pure, it will turn into powder."
"So you came up with a scam when you saw this?" Wang Huadong looked at Tian's mother and felt sad.
"Historically, 100 years ago, the Eagle Country scientific expedition team was on their way to Antarctica, but they all froze to death on the Antarctic ice sheet because their kerosene leaked out. The reason was that the iron barrels were welded with tin, and they all turned into dust in the low temperature." Bai Song said, "Tin plague was discovered by Aristotle several hundred years before Christ, but the scientific expedition team 100 years ago didn't remember it, so it is considered relatively unpopular knowledge. I didn't notice this before I came here, and I thought it was some kind of incense ash."
"This is fucking awesome..." Captain Peng and several other criminal police officers were whispering to one another, while some of them started looking for this thing on the Internet using their cell phones.
Tian's mother looked at Bai Song with a confused look and a mixture of fear and anxiety.
She didn't understand anything else, but what Bai Song said, such as "silver will turn into powder under divine power", was true!
How could the police know this?
She...didn't understand anything else he said, she only heard this...
She felt dizzy.
