The military order was like a mountain, and Zuo Zhong gave an order, and the personnel of the Military Unity Office and the Second Office immediately launched an investigation around the movement tracks of the subordinates in the mansion and the traces of the bonfire.

The entry and exit records are easy to find, and the attendant's office attaches great importance to this aspect. Except for the bald couple, anyone who enters and exits the Huangshan official residence must sign for confirmation.

The records include the exact time of entry and exit, the list of items carried, the reason for going out, and the contact person, in order to facilitate identification after the accident.

After receiving the request for assistance from the military command, the staff in the attendant room handed over the record to Wu Chunyang, emphasizing that every piece of information in it is absolutely true.

Whether Wu Chunyang didn't comment on this, whether it is true or not depends on the results of the investigation. When the official residence was bombed, the attendants were also suspicious.

He quickly returned to Yunxiu Building with the entry and exit record, handed it to Zuo Chong who was observing the surrounding forest with a telescope, and suggested in a low voice.

"Senior seat, I found it. Do you want to send someone to take over the security work? I'm worried that the eyeliner is in the attendant's room, which will affect our investigation."

"No need."

Zuo Zhong didn't agree, he was just joking, whoever is in the attendant room, if he offends this group of heavenly (separated) close officials, life in the military command will be difficult in the future.

However, Wu Chunyang's worry is not unreasonable, now everyone is suspicious, Zuo Zhong looked at the records, and gave him a trick by the way.

"understood."

Old Gu said that someone lit a fire on the mountain to guide the Devil's plane on the ground. We must find out whether this person is inside the mansion, and we did not focus on the outside of the investigation.

With so many people in the mansion, assuming someone entered and exited outside the recorded time, there would definitely be witnesses, which was easier than looking for a needle in a haystack to check the relatives of the suspect. "

Gu Qi scratched his head after hearing this, why does this sound so mysterious, how can one's footprints reveal the basic information of a person, but he readily agreed.

After all, the deputy director often had similar whimsical ideas, and the final results proved that these seemingly wild ideas were effective, so he immediately sent someone to send the extension down the mountain.

"Senior seat, you are here, this is the scene."

However, this subject is in its infancy at this stage. In the past few years, some people in the police station in the Shanghai Concession have done some research, but it is not too profound to be practically applied.

For the analysis and identification of footprints, it is possible to judge a person's height, age, weight, walking posture, etc., and also analyze the remaining time and walking direction.

I can only give you three days. This task is difficult and requires a lot of manpower. If necessary, I can ask the second office to support you. "

As long as you find these clues, you can use them to trace the opponent's trajectory. Don't doubt that the power of the country (separation) machine is huge when it is fully mobilized.

Zuo Zhong looked at the rubbings that were not very clear and entered the gods. Was the person who set the fire a soldier, or was the enemy trying to mislead them, so can we find clues through the footprints?
Footprint identification is an important branch of criminal technology in later generations, and it is a kind of trace in trace identification, and it plays a role that cannot be ignored in criminal investigation.

"Come here, let the kitchen of the mansion make some ginger tea and send it to the foot of the mountain. Watch it, and let the chef drink it first after cooking, so as to prevent someone from poisoning (partitioning)."

However, looking at the burnt black and compacted soil, Zuo Zhong felt that there might not be any useful clues in the fire scene, but there was hope in the outer (divided) perimeter.

Wu Chunyang saluted and left, the pressure in his heart was a bit heavy. Before, the deputy director was considering matters other than the case, but now it was him.

Soon pots of steaming ginger tea were picked up to several search spots, and the spies went down the mountain in batches to drink some tea to warm their bodies, and their morale, which had been a little low, began to recover.

No matter who set the fire, unless he can fly, the first thing to do is to climb up from the bottom of the mountain, and the footprints and moving traces along the way are indispensable.

Even if you can see the road clearly, it is not a pleasant thing to trek in the airless, wet and cold mountain forest in early winter, and it will take a lot of physical exertion.

After pondering for a while, Zuo Zhong handed the record back to Wu Chunyang and said slowly: "Chunyang, check whether the time of entry and exit has been falsified, the old rules, relevant witnesses and circumstantial evidence are indispensable.

Still the same sentence, everything depends on the evidence, don't jump to conclusions in a hurry, lest the enemy lead you into a ditch, Zuo Zhong checked every word very patiently.

There is no sign of signing on behalf of the signature, and some handymen who cannot write use their fingerprints instead. The work is very detailed and fully complies with security regulations.

In addition, if the person who leaked the location of the official residence is here, it is impossible for the other party to notify his accomplices by phone, and he will definitely find a way to get out. The investigation of relatives you mentioned earlier is a good idea.

Seeing that the footprints were being sent away, Zuo Zhong went to the bonfire trace and squatted down to observe for a long time, but unfortunately he didn't find anything, so he had no choice but to give up, got up and stood on the edge of the cliff and looked forward.

Gu Qi pointed to a piece of land with traces of fire and said that at this time, several technicians in white clothes were surrounding the scene to take pictures and collect evidence.

As for the reasons for going out and the list of items, the problem cannot be seen just by looking at it, and he is not a fortune teller (separation), which requires further investigation and verification.

Worried that his subordinates would catch cold in such an environment, Zuo Zhong asked a small secret agent to prepare for the war. He would do logistical work after the war. It couldn't be said that the case was not solved, and the operatives fell first.

Secondly, to be able to grasp the gait characteristics of the people who left behind the footprints. It is necessary to know that people have habits in walking, and these habits are repeatedly formed and fixed in life.

Facing his proposal, Zuo Zhong~ nodded and shook his head: "It's possible, and it's only possible, let's walk on two legs, we can't afford any mistakes.

Studying footprints can firstly help scouts figure out the structure of the feet and shoes and socks of those left behind in the footprints, so as to carry out later investigations.

This is also the reason why the national government set this place as the rear. There is not enough anti-aircraft firepower and fighter jets, so they can only rely on the power of nature to stop the Japanese.

Sure enough, Gucci brought another footprint plaster extension board and introduced: "After discovering the scene, I immediately asked people to search nearby, and found a string of adult footprints not far away.

But this has brought great difficulty to the search work. At this time, the sun is just rising, the surface of the mountain is covered with mist, and the visibility is very low. If you are not careful, you will fall into the mountain stream.

There is a reason for going out in the record. I need to tie (separate) the two together to see if there is any mismatch. I want to know where they went, who they met, and what they said after they went out. .

As soon as the morale was high, things went smoothly. Around ten o'clock in the morning, the first trace of a bonfire was found, which was located halfway up a hill one mile southeast of the Huangshan official residence.

In the 24 hours before the incident, no one left the official residence. The person who guided the Japanese bomber seemed to come from outside, provided that there was no problem with the record itself.

Try to see if you can sum up some rules, the purpose is to be able to see the basic information of the target from the footprints, this is not easy, tell Dr. Ling not to worry, as a long-term task. "

Wu Chunyang didn't complain, none of the cases they handled in the past was urgent, so he thought carefully for a few seconds and gave an answer and asked a question.

Seeing that the old subordinate had figured it out, Zuo Zhong focused all his attention on the entry and exit records. Since the bald couple had not moved to the mountain city for a long time, there were not many records.

When the footprints are well preserved, it can also track and trace, or use the footprints as a source of smell for police dogs to directly capture and identify criminal suspects.

Due to differences in various factors such as gender, age, height, weight, occupation, and walking posture, each person's gait characteristics are also different.

He looked at his watch and set a time-limited task for the first department. The whole government is paying attention to the case of the attack on the bald head, and they must solve the case in the shortest possible time.

Army boots?

"You can tell the person in charge of the attendant's room to ask them to conduct a self-inspection first, and the other party will accept your sympathy no matter whether the investigation finds any problems.

After thinking about it, he raised his binoculars to look at the distant mountains and forests again. Teams of two special agents were searching for the bonfire inside, which was not an easy task.

After receiving the news, Zuo Zhong brought a few guards to the scene. God knows if there are any spies hidden in the woods. It's better to be careful. Carelessness is a taboo in this business.

Don't forget that the military command has just been established, and your promotion by leapfrogging (separation) blocks the way of others. I don't know how many people are waiting to see your jokes. Safety comes first. "

Countless information flashed through Zuo Zhong's mind, he raised his hand and tapped on the extension board: "Send this thing to Ling Sanping, let that guy find some samples of footprints of different ages, heights and weights.

It wasn't until now that he realized how difficult it was for the other party. It was really difficult to be a good player in the intelligence agency without affecting his work.

All the way to the hill without incident, under the guidance of the secret agents who stayed at the foot of the mountain, everyone walked into the thick fog and climbed to the mountainside, where they met Gu Qi and others smoothly.

In addition, it is located in the eastern part of the Sichuan Basin. Due to the influence of the terrain, the ground wind is relatively small, which makes the mountain city more likely to form fog than other areas at the same latitude.

Wu Chunyang nodded after listening and said yes, this is the best way to deal with it, not only not offending others, but also eliminating risks, and by the way, he can make friends with the powerful figures in the attendant room.

Chunyang, to be an officer, you must not only do a good job, but also handle the relationship with your colleagues. Be a person and do things from the perspective of win-win. "

Zuo Zhong looked at the preoccupied Wu Chunyang and smiled. A person's life is a process of continuous growth. If you want to go up, there will be such a day.

There is no shortcut in the detection process, but there are detection ideas. Finding the right direction can get twice the result with half the effort, otherwise it will waste too much time.

Since our people are wearing cloth shoes and leather shoes, and the other party is wearing military boots, the two are easy to distinguish, and the footprints are very fresh, it is basically certain that they were left by the enemy. "

The mountain city is located at the intersection of Changjiang, Jialingjiang, and Yangzijiang. The air is extremely humid, and the relative humidity is above 80.00% throughout the year.

"Yes, deputy seat, I'll arrange it right away, it's just that the leaker and the ground guide may be the same person, if so, I suggest to check the ground guided spy first.

But just like what the attendant room said, the content is very comprehensive. For example, the clerks and handymen of the official residence have visited relatives once during this period, and only a dozen of the guards have gone out.

The Huangshan official residence in the distance shrouded in clouds and mist appeared and disappeared, like a fairy palace, and then he raised his neck to look at the thick gray clouds above his head, and slowly closed his mouth.

It looked like it was going to rain, and when the heavy rain fell, many of the poor evidence and clues that were originally scarce would disappear. Thinking of this, he suddenly turned around and gave Gu Qi an order in a deep voice.

"Send police dogs to follow the spies' footprints. It's only a few hours away from the incident. If you have the sniffing conditions, try to recover the enemy's trajectory. I want to know where the other party came from.

Then let all the people go up the mountain, and make sure to find all the traces of the bonfire before noon today, you and me are no exception, we have to compete with God for time, and hurry up to notify. "

Just at this time, there was a dull thunder, and the originally not bright sky became gray, and then the wind suddenly picked up, and Zuo Zhong's windbreaker was blown loudly.
