Although this little catcher had brought them too many surprises in the previous time, when Qi Ping shouted these words, the crowd was still briefly silent.

Many people looked confused.

It felt like watching a movie, suddenly skipped a section, the plot changed suddenly, and the audience was at a loss.

Aren't you interrogating?

You clearly had no clue before, so why did you suddenly... identify the murderer?

I can't keep up with my thinking.

Wait... When people recalled the conversation between the two, Zhao Zhixian's eyes burned brightly:

"What do you know? Have you ever seen those merchants?"

This is the only possibility.

Qi Ping pointed out the appearance of the five merchants, which showed that he had probably seen them before and had some key information.

However, Qi Ping's answer was surprising.

"My lord, I have never seen you in this humble position."

"Nonsense, do you think we are deaf? How can you tell your height and appearance if you have never seen us?"

Wu Captou felt that his intelligence was insulted and he fell into the role of admiration.

Qi Ping smiled lightly and said: "It's true that I haven't witnessed it, but who says that I can't guess these things if I haven't seen them?"

He looked around at everyone and said:

"You all still remember that I just said, 'Every contact must leave traces.' It just so happened that when I inspected the scene before, I found some traces. Please follow me, two adults."

As he said that, he led everyone straight to a certain courtyard wall.

It was originally dark here, but once a lamp was illuminated, it immediately became as bright as day.

Under the courtyard wall, there were messy footprints in the mud.

Qi Ping held a lantern and said:

"I asked Wang Dianshi before and learned that when the government arrived, the door of the palace was locked, which means that the gangsters entered and exited by climbing over the courtyard wall.

It happened to have been a light rain a few days ago. The wall was away from the sun and the soil was moist. It must have left traces. After searching, I found something."

He pointed to the ground and said: "The footprints here are different, there are exactly five people in total."

Everyone was stunned.

Behind them, the two princesses who followed were also enlightened. No wonder Qi Ping was walking around the courtyard wall alone with a lantern before, and it turned out that he was looking for footprints.

"I see, but this can only determine the number of people. How can you tell if the gangster is tall, fat or thin?" Governor Li expressed doubts.

Qi Ping said calmly:

"It's still footprints! What you don't know is that human footprints can reveal far more information than many people think.

Take height as an example. Human beings are in tune with the aura of heaven and earth, and their body is a mystery. Generally speaking, the height of a human in the prime of life is seven times the length of his feet, followed by teenagers and the elderly.

In addition, generally speaking, the length of the foot is similar to the length of the forearm.

I don't have a ruler in my hand, but I can roughly estimate the gangster's height by comparing it with my own footprints.

Of course, what we are talking about here is barefoot foot length, so if you want to calculate accurately, you have to remove the influence of shoes, which is easy.

According to the pattern on the ground, find the shoes in the market, use the same ruler and subtract the excess."

As he said this, he felt a little emotional in his heart.

The miscellaneous books I read in my previous life recorded the "Footwork Tracking Technique" of modern criminal investigation. The exact formula is as follows:

Height = footprint length × 6.876

At that time, I just thought it was interesting. Who would have thought that the knowledge would actually be useful one day.

At this moment, after hearing Qi Ping's words, everyone present felt confused and confused. Magistrate Zhao looked at Wu Chuan:

"Is there such a saying?"

Wu Captou hesitated and said:

"The human body does have strange laws. I have heard the elders say it, but this seven-fold theory has never been heard of."

Qi Ping said: "If you don't believe it, you can test it on yourselves."

Immediately, someone tried to compare and was shocked:

"Really! It's exactly what Agent Qi said."

Qi Ping smiled and said: "Similarly, in the mud, if you are fat, your footprints will be deeper, while if you are thin, the opposite will happen. If you are carrying heavy objects in your hands, the depth of your feet will be different."

"In addition, people of different ages and genders have different steps and forces on the front and rear soles of the feet."

"Also," he raised the lantern in his hand and shined it towards the courtyard wall:

"When people climb over a wall, they step on the wall to gain strength, and the height of the footprints left behind can also prove their height."

When everyone looked around, they found footprints on the wall.

Qi Ping concluded:

"So, after I saw the footprints, I already had a preliminary picture in my mind.

Then, I thought about it, if the other party had premeditated it and might have arrived in the city a few days earlier, what identity would they show themselves to?

In this day and age, those who walk around without attracting attention are most likely merchants."

After a pause, he said calmly:

"Therefore, after grasping these, and confirming it with the restaurant clerk, it can be confirmed that there are five gangsters in total, dressed in business attire, all of them are strong men, tall, short, fat and thin, and their appearance has been exposed for a long time."

Having said this, he closed his mouth and took a step back to give everyone time to think.

Having reached this point in derivation, there is nothing more to say.

There was a brief silence.

Governor Li looked at him for a few seconds and sighed:

"My officer, I still underestimated you after all!"

This reasoning is really wonderful.

From the first three doubts, the hidden details of the case are derived.

Then, starting from the Sun Mansion, combining trace studies and interrogation to corroborate each other, we came to the conclusion that the entire logical chain is linked to each other, clear and powerful, and has no flaws.

You can almost take it out and use it as a model to learn from.

How can you not surprise and admire him?

Not only him, but at this moment, County Magistrate Zhao, Li Dianshi, all the government officials, and even the tough-talking Wu Chuan were all impressed in their hearts.

In such a short period of time, everyone was clueless and helpless.

As a result, a young detective quickly sorted out the mess, cleared away the fog, and identified the murderer.

This operation dazzled these rough guys, and many of them didn't even understand...

"Yongning, is it really true that there are hidden dragons and crouching tigers in all parts of the dynasty?" Princess Anping, who has a lively temperament and delicate appearance, murmured, "A subordinate official from a remote small county is so capable."

She was conquered.

I just feel that the various story-telling novels I have read in the past are far less exciting than what I see today. The talents, beauties, gods, ghosts and demons in the book are all overshadowed.

The eldest princess in a purple dress and pierced eyes shook her head silently, saying to herself that at such an age, with such intelligence and bravery, she would be considered a hero even in Kyoto.

After being shocked, a certain idea in my heart became more and more certain.

Ahead, Governor Li sighed, calmed down his mood, and said in a deep voice:

"Master Zhao, now that the goal is clear, how long will you wait?"

Zhao Zhixian was stunned, quickly bowed his hands, and then said loudly:

"Did you hear what you just said? The Heyan County Government heard the order and immediately began to search the inns in the city. Once discovered, they must not act rashly and report back as soon as possible! At the same time, using the memories of the restaurant clerks, they described the appearance of the gangsters and posted them throughout the city..."

In an instant, orders were issued one after another, and all the government officials took their orders and left.

Only part of the processing site is left.

In an instant, the crowded Sun Mansion became much empty. Qi Ping was hesitating about where to go when he heard Governor Li say:

"Qi Qi is a young and talented young man who is even rarer and has superb skills in solving crimes.

There are many doubts about this case, and it may be difficult to catch the culprits for a while. In my opinion, Qi Ping will temporarily take over the role of the arrester, command the government officials, and be responsible for the investigation. Mr. Zhao, what do you think?"

Qi Ping suddenly raised his head.

Zhao Zhixian Dui laughed and said: "It all depends on the governor!"

After saying that, he looked at Qi Ping with complicated eyes: "Are you willing?"

Challenges are also opportunities... Qi Ping took a deep breath, cupped his hands and said, "In this humble position, I will do my best!"

In the distance, Wu Chuan, who was about to walk out of the house, paused, looking confused.

Qi Ping temporarily takes over as head arrester?
