Hearing this, Chen Hao nodded with satisfaction, pointed at Du Chao and Du Yue behind him and said, "First let the police dog smell the scent of these two people."
Zhao Tianjun signaled to the police officer beside him.
Four police officers led police dogs forward, circled around Du Chao and Du Yue for a few times, and then stopped.
Zhao Tianjun said: "Leader, I have already heard it."
Chen Haodao: "You leave for a while, I will hide these two people, and then you come back and use police dogs to look for these two people."
"yes."
Zhao Tianjun and four police officers left with their police dogs, and soon disappeared.
Chen Hao looked at Du Yue: "Du Yue, use a layer of water vapor to isolate you from Du Chao."
Du Yue is still in a hypnotic state. After hearing this, he immediately used his super power to condense the moisture in the air, covering himself and Du Chao with a layer of water vapor.
As everyone watched, they saw that this layer of water vapor was like a transparent mask on the head of a space suit, shrouding Du Chao and Du Yue inside.
Chen Haodao: "Previously, Du Yue said under hypnosis that the reason why police dogs could not smell him and Du Chao was because this layer of water vapor blocked the smell. Since it is impossible to lie under hypnosis, let's take a look at what he said.
Isn’t that true?”
After the words fell, Chen Hao stretched out his hand and Du Chao and Du Yue turned around at the same time and walked to a hidden corner dozens of meters away to stop.
Chen Hao shot two spiritual arts, which landed on Du Chao and Du Yue respectively.
Du Chao and Du Yue disappeared instantly.
Everyone was surprised.
Chen Hao explained: "I used extraordinary means to make them temporarily invisible, but in fact they are still there.
This is to simulate the situation when Du Chao and Du Yue were buried. The police dogs could not see them and had to rely on their scent to find them."
Only then did everyone realize.
Chen Hao signaled to Ling Duhe, who immediately called Zhao Tianjun.
After a while, Zhao Tianjun and four police officers came back with their police dogs.
Chen Haodao: "Captain Zhao, I have asked those two people to hide. Can you let the police dogs search and see if they can be found?"
"yes."
Zhao Tianjun led the police dog to the place where Du Chao and Du Yue had just stood. He signaled a few times, leaned over and touched the police dog's head, and then let go of the reins in his hands.
Other police officers also made the same move.
The five police dogs first sniffed on the spot a few times, and then chased in the direction where Du Chao and Du Yue were walking while sniffing.
Soon, they tracked to the corner where Du Chao and Du Yue were, and then kept circling and barking.
Apparently, the police dogs sensed that the scent was here, but couldn't see the target, so they were confused.
Zhao Tianjun and others didn't know what was going on and were very shocked.
Everyone looked shocked.
Du Yue had isolated himself and Du Chao's bodies with a layer of water vapor, but the police dogs could still smell the scent of the two men, which obviously proved that what Du Yue told was a lie.
But what Du Yue said was under hypnosis. Logically speaking, it is impossible to lie! Chen Haodao: "This is the ideological stamp that makes you think that you are not lying, but in fact, it is not the truth."
While he was talking, he used his spiritual skills to remove Du Chao and Du Yue's invisibility and reveal themselves.
The five police dogs were startled and quickly ran back to their master.
Everyone was shocked and nodded.
If the results of the polygraph were not enough to prove the imprint of thoughts, then they had no choice but to disbelieve Chen Hao's experiment of isolating odors with a layer of water vapor.
Yang Wenbao asked: "Chief instructor, how do you know that the water vapor layer cannot isolate the smell?"
Others also cast curious glances.
Chen Haodao: "If you read more books, you will know that the water vapor layer can indeed isolate the smell, but the degree of isolation is limited.
For humans, the sense of smell is underdeveloped, so once the water vapor is separated, they cannot smell it.
However, dogs' sense of smell is thousands of times more developed than humans, and water vapor cannot block their sense of smell at all.
So I take it for granted that water vapor blocks odors, it seems reasonable, but it’s actually pseudoscience.”
Everyone was stunned.
"I see."
Yang Wenbao said, then his face was full of shame: "I'm sorry, Chief Instructor, I made the suggestion to hypnotize Du Chao and Du Yue before. When I saw them admitting that they were the murderers, I thought the dust had settled and the case could be closed. I forced you to do it in public.
Make a choice.”
"It seems now that I was very wrong.
If you hadn't been foresighted and stood up for yourself, I would have wronged a good person!"
"Alas, I clearly know that I know nothing about the supernatural realm and should not jump to conclusions, but I still made an empiricist error. I am really stupid!"
When everyone heard this, they were secretly ashamed.
They thought just now that Chen Hao was deliberately shielding Du Chao and Du Yue, but now it seems that Chen Hao is right.
Chen Haodao: "You don't have to blame yourself, ordinary people can't think of methods like ideological stamping.
And if it weren’t for your hypnotic suggestion, I wouldn’t be able to prove Du Chao and Du Yue’s innocence so quickly.”
Having said that, Chen Hao secretly used his spiritual consciousness to enter Yang Wenbao's mind.
He has a suspicion and must find out.
Suddenly, Zheng Liguang said: "Chief instructor, I think this experiment alone cannot prove the existence of the ideological stamp."
Um?
Everyone looked at him in surprise.
Chen Haodao: "How to say?"
Zheng Liguang said: "Under hypnosis, Du Chao and Du Yue have no independent consciousness and can only answer based on their memories, so they will not lie. So as long as they really believe in their memories that the water vapor layer can isolate the smell and the police dogs cannot smell it, it will be fine.
Yet?"
Before Chen Hao spoke, He Yongsheng said: "But experiments have proven that the water vapor layer cannot block the smell, so the memories of Du Chao and Du Yue are not real, but false memories imposed on them by the stamp of thought."
Zheng Liguang said: "I know that based on experiments, it must be other factors that allowed Du Chao and Du Yue to escape the search of police dogs in the burial place.
But Du Chao and Du Yue may not know that it is other factors, and still mistakenly think that the water vapor layer blocks the smell, so isn't it normal to say this after being hypnotized?"
Everyone was startled and looked thoughtful.
What Zheng Liguang said does make sense.
He Yongsheng said: "Leader Zheng, you also said that Du Chao and Du Yue may not know that it is other factors. This is just a possibility."
Zheng Liguang asked: "But this possibility exists, doesn't it?"
He Yongsheng stopped talking.
Zheng Liguang looked at Chen Hao with burning eyes: "Chief instructor, what do you think?"
Chen Hao smiled faintly: "I guessed that you would be serious.
It doesn't matter, in order to convince you, I will personally demonstrate to you what the ideological stamp is."
He waved Du Chao and Du Yue back, then pointed at the two of them and said, "Right now, they are still in a hypnotic state and have no independent consciousness, so they will only answer questions based on their memory and will not lie, right?"
