Shi Wenshan said: "Then I will tell Captain Li to concentrate on searching the suburbs of Meihua Town."
Lin Suxin asked: "Meihua Town is surrounded by mountains on two sides and the sea on one side. The uninhabited area is vast. Will it be difficult to search?"
"It's very difficult."
Shi Wenshan said, "Captain Li and the police force in Meihua Town alone are simply not enough. We need to apply for support from the Hedong City Criminal Police Brigade."
"Director Shi, you don't need to call me yet."
Chen Hao said, "I have a way to confirm the traces of the murderer. Once confirmed, it will not be too late to search again."
"any solution?"
Lin Suxin and Shi Wenshan asked in unison.
Chen Hao smiled and did not answer, but asked: "Have you forgotten the acid?"
"Of course I haven't forgotten it, but what does this have to do with the murderer's trace?"
Lin Suxin asked curiously.
"It has a lot to do with it."
Chen Haodao, "Judging from the situation described by Brother Yu, there are two mysteries that have not been solved for the time being. One is the murder weapon used by the murderer, and the other is strong acid. These two things must exist, but Brother Yu said very clearly,
When we rescued the murderer, he was wearing only a pair of underwear and didn't carry anything with him. This is the most contradictory and critical aspect of the entire case."
Shi Wenshan wondered: "Is it possible that Lao Yu was too frightened. Even if he regained consciousness, he couldn't remember some parts, so he made up his mind."
"It's possible, but it's not very likely."
Lin Suxin said, "We have examined the body before and determined that the murderer used a very sharp long weapon. Of course, I have discussed this with Chen Hao before. It is possible that the murderer's martial arts have a blade effect, which can be explained, but the source of the strong acid
But it can't be explained. If Brother Yu remembers it wrong, the murderer was wearing clothes and carrying strong acid, but whether the murderer intentionally attacked or accidentally leaked it, it cannot explain that the traces of strong acid corrosion on the fishing boats and corpses are extremely small and scattered irregularly.
And the fact that the murderer himself was not harmed."
Shi Wenshan nodded.
"It can actually be explained."
Chen Haodao said, "The strong acid was produced by the murderer. His body fluids and saliva are the strong acid!"
Lin Suxin and Shi Wenshan were shocked.
"How can this be!"
Shi Wenshan immediately shook his head, "How can human body fluids and saliva be acidic? It's ridiculous."
Lin Suxin said nothing, but she also showed a look of disbelief.
"If all impossibilities are eliminated, what remains, no matter how incredible, is the truth."
Chen Hao said slowly.
Shi Wenshan looked shocked, but still said firmly: "Mr. Chen, although what you said makes sense, I still can't believe that such a person cannot exist in the world."
Lin Suxin said: "Chen Hao, I had the same idea as you just now, but if a person's body fluid is strong acid, then the person himself will be corroded by the strong acid and cannot survive at all. This is against physiological science."
Chen Hao did not defend himself: "Well, let's go to the location of the murdered police officer to check. That was the place where the murderer last disappeared. If my guess is good, we should be able to find some traces."
"Mr. Chen, the place where the police officer was killed was on the highway."
Shi Wenshan said, "Now that it has been so many days, the highway has long been opened to traffic. Even if there are any traces at the scene, they must have disappeared."
"Just go and take a look and you'll find out."
Chen Hao smiled.
Lin Suxin said: "Director Shi, let's go take a look, otherwise there is nothing to do now."
"All right."
Although Shi Wenshan disagreed, Lin Suxin and Chen Hao were superior leaders after all, so they naturally had no objections.
The three people returned to Meihua Town in a police car.
About a kilometer away from the town, the police car stopped by the roadside.
"Mr. Chen, Leader Lin, this is where the police officer died."
Shi Wenshan got off the car, pointed at the road, and said with a heavy expression.
The police officers who died were all the backbone of the police station. We usually get along well with each other, but we didn't expect that after May 13, we would be separated forever. Shi Wenshan would feel very sad every time he passed by this place.
Chen Hao patted his shoulder comfortingly and scanned it with his spiritual consciousness.
One side of this road is close to a mountain, the other side is low-lying gravel land, and about fifty meters further ahead is the sea full of rocks.
After Chen Hao scanned the gravel ground, he cast his consciousness towards the mountain peak.
The mountain peak is not high, only a few hundred meters, but close to the road is a sharp cliff like a knife. Looking up from the road, it looks very steep.
"Director Shi, what is the name of this mountain peak?"
Chen Hao asked while scanning the mountain wall.
"There is no official name. We local people call it Xiaohaishan, and the other slightly larger one is called Dahaishan."
Shi Wenshan said, "Although these two mountains are not big, they produce some very unique wild mountain products. When fishermen are not busy fishing, they often go up to the mountains to pick them, and then transport them to the city to earn some extra money. When they are free at night,
I’ll take some mountain products and ask the two leaders to try them, it tastes very good.”
"Then thank you Director Shi."
Lin Suxin said, walking to Chen Hao, "I looked and found nothing."
Chen Haodao: "I have discovered something."
"What discovery?"
Lin Suxin and Shi Wenshan suddenly became energetic.
Chen Hao walked to the cliff, stretched out his hand and pointed: "What do you think this is?"
The two of them opened their eyes wide and looked where he pointed.
I saw that it was a very small hole in the rock wall, which looked very inconspicuous. If Chen Hao hadn't pointed with his finger, he probably wouldn't have noticed it even if he was standing in front of him.
Or even if they are discovered, they will think that it is formed by the weathering of the rock wall and will not take it to heart at all.
However, Lin Suxin and Shi Wenshan looked shocked and said in unison: "A small hole corroded by strong acid!"
After the autopsy, both of them were deeply impressed by the strong acid corrosion. They could see at a glance that the small hole in the rock wall was almost exactly the same as the small hole in the corpse that was corroded by strong acid.
"good."
Chen Haodao, "If it is weathering corrosion, the edges of the small holes in the rock wall will not turn black. It is obvious that these are traces of oxidation caused by strong acid corrosion."
He stretched out his hand and pointed to the top of the small hole in the rock wall: "There is one here too."
Lin Suxin and Shi Wenshan looked up, and sure enough, there was an identical small hole about fifty centimeters above the small hole in the rock wall.
Chen Haodao: "There are more up here, and there are quite a few of them, all the way to the top of the mountain."
The two looked up.
As a warrior, Lin Suxin has excellent eyesight and can see many small holes that wind upwards. Shi Wenshan is just an ordinary person. Even with sore eyes, he can barely see a few.
But naturally he would not doubt Chen Hao.
"Mr. Chen, how did you find out?"
Shi Wenshan couldn't help but exclaimed.
I'm afraid no one will notice such a trivial trace.
Chen Hao smiled, he naturally saw it with his spiritual consciousness.
"Obviously, after killing the police officers who blocked the road, the murderer did not flee along the road or return to the sea, but directly climbed the cliff and entered Xiaohaishan."
Chen Haodao, "These small holes in the rock wall were corroded by the body fluids or saliva left by the murderer when he climbed."
