With Jiang Hao, who is equipped with tracking skills, everyone in the Criminal Investigation Department who was originally going to collect all the evidence submitted by the Union Police Station has become busy again, because they need to record the new evidence found by Jiang Hao from the new record, of course, the most important thing is to learn Jiang Hao's case-solving skills.

Jiang Hao's keen observation, accurate clue analysis, and rich life experience all made everyone in the investigation department who was proficient in criminal investigation feel incredible, and many of them were ashamed of themselves and cast a worshipful look at Jiang Hao.

"I'm really overthinking."

Jiang Hao's fast, and reasoned and well-founded clues inferred made Feng Chaoyang's confidence smaller and smaller, with Jiang Hao's self-taught reconnaissance ability, where did he still need his teaching, and even he wanted to ask Jiang Hao for guidance in some places.

"The direction in which the soot falls is certainly affected by the wind speed, but it can also accurately reflect the mood of the attractor at the time.

Even the direction of the falling soot can also guide the direction of the criminal's escape, because what people unconsciously show is the closest to what they think in their hearts. ”

Jiang Hao was very useful for the admiring gaze cast around him, and continued to transmit the knowledge obtained from the tracking technique interface, of course, the amount of information fed back by the tracking technique was very small, but Jiang Hao was quite skilled in the ability to flicker and add branches and leaves.

"Really?"

Although the people in the Criminal Investigation Bureau had seen Jiang Hao's unrivaled investigation ability, everyone rummaged through their memories and did not find the slightest theory about the direction of the soot falling that could guide the criminal's escape.

For example, the theory of solving cases with footprints is the most important theory of case solving in criminal investigation, and the hardships experienced from its research to its formal adoption are unimaginable.

If Jiang Hao's soot theory is confirmed, then Jiang Hao's contribution to the criminal investigation community will be huge, which is bound to cause a huge sensation in the criminal investigation community.

"Verify it, and you'll know the way."

Jiang Hao directly lit a cigarette and put it in his mouth, in order to prove that his theory was correct, he immediately put into the role of acting in front of all the criminal investigators.

Syllable!

Jiang Hao walked slowly towards the suspicious criminal investigation officer, but his hand flicked the burning smoke every time, and under his flick, the soot breeze flew up, fluttering for a while and falling to the mud.

"See what?"

After Jiang Hao's performance went through, he questioned the puzzled criminal investigators, he did a test walk, but he didn't think anyone could really see the clue from it, the reason is very simple, he thinks that his theory still needs to be verified, but now it is enough to show his case-handling methods.

"Nope."

The people from the Criminal Investigation Department did not disappoint Jiang Hao, they shook their heads in unison, recalling Jiang Hao's movements, it seemed that it was just a person with a cigarette walking, and he really didn't see anything unusual.

"How can I explain that?"

Jiang Hao stretched out his finger and knocked his head in embarrassment, and said suggestively: "You may not be able to accept my explanation, why don't you go through it like me, let's have an interactive activity, I believe that after this activity, you will have an understanding of my soot theory." This time, though, I have to make one more request. ”

"What a request."

The theory proposed by Jiang Hao made the people in the Criminal Investigation Department interested, if they could participate in an activity to understand the theory proposed by Jiang Hao, it would be the best of both worlds, after all, the boring theoretical knowledge was not as fast as the hands-on practice, but they were all very curious, what requirements Jiang Hao could put forward.

Feng Chaoyang also pricked up his ears, wanting to see how Jiang Hao wanted people to cooperate.

"The request is simple." Jiang Hao looked around at the puzzled crowd and said with a smile: "You have to make a corresponding natural reaction according to the emotions I prompted.

The so-called natural reaction is how you react when you encounter a similar situation, and I would like to remind you that what I need is not how well you perform, but the most realistic physical reaction. ”

"Okay."

The people in the Criminal Investigation Department all nodded happily in agreement, feeling that Jiang Hao's experiment would definitely be particularly interesting.

"Professor Feng, let's be the first one."

Jiang Hao found that Feng Chaoyang was very interested in this experiment, and with Feng Chaoyang's prestige, if he could admit the authenticity of the soot theory, others would presumably trust it more, which is the so-called celebrity effect.

Hearing that he was the first to play, Feng Chaoyang was slightly stunned, he originally wanted to analyze the feasibility of Jiang Hao's theory through the participation of others, after all, if a powerful theory cannot be used in solving cases, the value of its existence will be reduced.

"Okay."

Feng Chaoyang nodded without thinking about it, and directly participated in the experiment, which was more realistic than a concise analysis, but he was worried about whether he would be able to perform well.

"Don't deliberately perform, just react naturally."

Jiang Hao reminded Feng Chaoyang again, then lit a cigarette, handed it to Feng Chaoyang, and nodded to signal that he could start.

Feng Chaoyang walked forward step by step as the first experimenter in the curious eyes of everyone, and thinking of Jiang Hao's entrustment, his body naturally relaxed.

"You are now a robber, you need to go fast to escape the pursuit......" Jiang Hao saw that everything was happening according to the plan, and directly started the experiment, and Jiang Hao never doubted the results of the experiment.

Feng Chaoyang followed Jiang Hao's prompts, and immediately imagined himself as a robbery criminal, in a panic to escape, his hand unconsciously raised his cigarette and took a puff, beads of sweat appeared on his forehead, his steps were fast, and the soot accumulated to a certain extent, Feng Chaoyang almost reflexively flicked the cigarette butt.

Whew!

The soot that was bounced off naturally fell to the ground, leaving a shallow trail of soot on the soil.

Jiang Hao glanced at the policeman beside him, and the policeman who got the signal started to quickly start at the place where the soot fell according to Jiang Hao's explanation, quickly measuring the distance between the wind speed and the soot, so that Jiang Hao could continue to verify the theory.

"You're being chased by the police, and you have a path in your heart that you want to take, but in order to escape, you have to abandon the original route for the time being."

Jiang Hao continued to guide, and when Feng Chaoyang flicked off the cigarette ash again, Jiang Hao directly shouted to stop Feng Chaoyang, who was selflessly invested.

"Did you feel anything halfway through?"

Jiang Hao took the cigarette in Feng Chaoyang's hand, snuffed it out directly, and asked Feng Chaoyang with a smile.

The people in the Criminal Investigation Department watched the first experiment in which Feng Chaoyang participated in the whole process, and they still couldn't figure it out, they all focused their eyes on Feng Chaoyang, and they also wanted to hear what the most vocal party had to say.

Feng Chaoyang thought about it carefully, and indeed didn't feel anything out of the ordinary, it was completely in accordance with Jiang Hao's prompts, selfless acting, looking at a pair of expectant eyes, and said helplessly: "I really didn't feel it." ”

"Don't feel it?"

"It doesn't seem like anything is happening, so it's strange to be able to feel it."

"What does Jiang Hao want to do?"

The people in the Criminal Investigation Department were all suspicious and whispered, looking at Jiang Hao's sworn appearance, they were all confused by Jiang Hao.

"Who wants to experiment?"

Jiang Hao was not in a hurry to announce the answer, looked around at the puzzled crowd, and asked in an unhurried tone.

"Why don't you just explain."

Even Feng Chaoyang, a footprint expert, couldn't notice anything unusual, and the people in the Criminal Investigation Department didn't want to continue to waste time participating in the experiment, and they wanted to know more at the moment how Jiang Hao would explain!

"In fact, this experiment is indeed enough to prove the theory that my cigarette ash can guide the fugitive's direction."

Jiang Hao glanced at the people who couldn't wait to know the answer to the Dao, and felt that the time was almost up, and it was time to announce his theoretical basis, pointing to the protected soot and saying, "Let the soot explain everything." ”

"Oh."

All the people in the Criminal Investigation Department were stunned, soot does not explain everything, and what can the remains of soot prove? In an instant, everyone pricked up their ears and held their breath, wanting to hear how Jiang Hao justified himself.

"Ordinary people take cigarettes flat, or hold them on their chests." Jiang Hao started to demonstrate while explaining, and then explained randomly: "But once a person encounters an emergency, there will be emotional instability in the individual, and even the posture of holding a cigarette will change.

This can be seen from the soot, you can see the distribution of the soot left by Professor Feng's fingers, it can be said that it is very even, but when I told him that the matter was urgent, he unnaturally showed nervousness, the speed of smoking was increasing, and the concentration of soot on the ground naturally increased rapidly. ”

"Yes, indeed."

The people in the Criminal Investigation Bureau nodded in agreement, and the sudden increase in soot on the ground was beyond doubt, but someone questioned: "But soot doesn't seem to have any necessary connection with judging the direction." ”

"Look here!"

Jiang Hao was not in a hurry to answer the doubts in everyone's hearts, but pointed to a messy cigarette ash and said, "This was the place where I asked Feng Chaoyang to choose a route, so I might as well judge the direction that Professor Feng once wanted to go through the distribution of cigarette ash." ”

"Really, fake."

Jiang Hao's words surprised everyone, but if you think about it carefully, this method is indeed the most direct proof scheme.

The most shocked person was Feng Chaoyang himself, because the direction he was going to did flash in his mind just now, could Jiang Hao be able to spy on my mind, but this is obviously impossible, then there is only one reason to explain, that is, Jiang Hao can really judge the direction that people want to go with the soot.

However, is it really feasible for soot to judge the direction? If he met someone else, Feng Chaoyang could say with great certainty that the other party was a liar, but when he was faced with Jiang Hao, who was constantly creating miracles, Feng Chaoyang was at a loss in his heart at this moment, and his eyes looked at Jiang Hao with a calm face, expecting Jiang Hao to give a reasonable reason.
