Because the case has not yet been closed, the door not only had a new lock, but also had a patrol room seal affixed.
Xu Siqi called the patrolman, opened the door with the key, ordered the patrolman to guard outside the house, and then walked in with Zheng Zheng.
They are conducting a normal investigation and will not arouse any suspicion.
After several searches, the house seemed a little messy. The police officers had found the hidden compartment under the high and low cabinets, and it was empty and empty.
The two of them searched separately but found no substantial clues.
Xu Siqi sat down, opened the drawer at hand, looked at it, and said, "I was also obsessed. I actually believed your words and came to search again."
Zheng Zheng also felt a little embarrassed. The house was not big to begin with, but it was searched three times by more than 20 people. It could be said that the ground was dug three feet deep.
"Idle time is idle, just think of it as a way to relax..."
He solemnly entered the kitchen, opened the closet and took a look. There was a blue brick in the corner. He reached out and took it out, muttering to himself: "What is this?"
Xu Siqi had already noticed it when he was searching for it for the first time. He just didn't say anything, hoping that Zheng Zheng wouldn't notice it.
Hearing the sound of the closet opening and closing coming from the kitchen, he stood up and followed in. He casually glanced at the blue brick in Zheng Zheng's hand and said, "What are you doing? You don't even recognize Brick."
Zheng Zheng frowned, looked at the green brick in his hand over and over, and said: "I know the brick, I'm just curious, why does Fang Yongyan put a brick at home?"
Xu Siqi took the green brick and smelled it, then handed it back to Zheng Zheng and said, "It smells of Chinese medicine."
He solemnly raised his nose and smelled it, and there was indeed a smell of Chinese medicine. He said, "How come there is a smell of Chinese medicine?"
Xu Siqi looked around, pointed to a medicine jar in the corner, and said, "Look there."
"What do you mean?"
"You still don't understand? It seems that you have never boiled Chinese medicine before. After the medicine is boiled, take the medicine jar off the stove and tell me where to put it?"
"Put it on the table."
"That medicine jar you just took off the stove? Is it terribly hot? I don't want to take it off the table."
"Put it on the blue bricks?"
"Yes, what's the purpose of the green bricks? It's for heat insulation."
"No? Siqi, have you ever boiled medicine?"
"When we were in Tianjin? My mother was in poor health and had to boil medicine every now and then? My father was too busy with work and had no time? I could only do this kind of work."
"Yes, yes, I forgot about this. Then, where did the smell of medicine on the green bricks come from? Oh, maybe the medicine was spilled..."
In Xu Siqi's mind, a scene like this appeared: Fang Yongyan brought a chair? Placed it directly opposite the transom? Then put the blue brick on it.
The reason why a blue brick was placed was because Fang Yongyan was not tall enough. If he wanted to touch the position of the transom, he needed to add the thickness of a brick.
Xu Siqi felt a little puzzled when he discovered the tabby cat entering and exiting the transom? Judging from the fact that the tabby cat is so familiar with the road, this is definitely not the first time this has happened.
With Fang Yongyan's observation skills? He must have known it for a long time, so why didn't he close the transom? To prevent the tabby cat from entering and exiting at will?
Seeing the green bricks and medicine jars today, Xu Siqi suddenly realized? The transom is always open? It is to facilitate Fang Yongyan to take things from the transom.
Is the transom window nestled in something like an attic? It can avoid rainwater intrusion and does not affect ventilation. However, every time you open and close the window, you have to lean into the attic.
Considering Fang Yongyan's height, this is not a big problem. If he puts a ladder at home, people who see it will first think of a transom.
Therefore, Fang Yongyan simply did not close the air window to avoid causing unnecessary speculation by others.
In the eyes of ordinary people, this is a very common thing. For a lurker, every detail must be considered.
For example, even if Fang Yongyan prepared a ladder, no one would notice it at all, but he would not dare to be careless in the slightest.
There was also the medicine jar, which was the key for Xu Siqi to determine that there was a problem with the transom.
Fang Yongyan highly respected science, especially in medicine. He once mentioned to Xu Siqi that he had never taken traditional Chinese medicine since he was an adult, and whenever he had headaches or fever, he always went to Western medicine.
How could such a person have a medicine jar at home?
The purpose of the medicine jar is just to explain the purpose of the blue brick.
In case anyone asks.
Buying a pack of herbal medicine and boiling the green bricks for half a day can basically hide it from anyone, except Xu Siqi who knows that he does not take traditional Chinese medicine.
In fact, Fang Yongyan took care of almost all the details, but unfortunately, despite all calculations, he still ignored Qiao Zhendong, who knew him.
Therefore, the sentence "nothing is missing" is actually a wrong sentence. No one can be perfect, unless it is not a human being but a god.
Xu Siqi sighed helplessly and said to Zheng Zheng: "With this time, what better to do than study on a brick for a long time? Do you think we are too busy?"
He solemnly placed the green brick on the ground, patted the dust on his hands, and said seriously: "Siqi, don't bother. In fact, this is how to find clues. The process is extremely boring. Not to mention a brick, even a glass of water.
There may also be potential clues."
"The problem is, I've searched the patrol room many times, so I don't think there's any need to waste time."
"The troops you are talking about..."
"Don't underestimate people. I am also a police officer who has been trained by the police station. Station Commander Zhou once said that the training of the patrol room is similar to the training of special agents."
"The training subjects in the patrol room are only for ordinary criminal cases. I don't believe that an agent of Fang Yongyan's level can find the clues he left with just a few patrol officers?"
"What you said seems to make sense..."
"So, Siqi, you should hurry up about going to Nanjing for training. The training methods of the Secret Service will be eye-opening to you!"
"I'm afraid it's not possible for the time being. It's only been more than two months since I was transferred to the Hongkou Police Station, and I'm rushing to apply for leave. Stewart will definitely not agree."
"It's really not appropriate to take a vacation just after becoming a detective..."
He solemnly took out his cigarette case and took a look. It was empty, so he said, "Inspector Xu, please give me a cigarette and take a rest."
Xu Siqi touched his pocket: "I forgot my cigarette in the car."
"Where did you put it?"
"In your coat pocket."
"key."
Xu Siqi handed over the car keys and said: "By the way, take a look at the rear tires. When you came here, why did you feel that the tires were under-inflated?"
"Which tire?" I asked solemnly.
Xu Siqi thought for a while: "It seems to be on the right side, right?"
He sighed solemnly and exaggeratedly: "Well, what you said seems to mean that I have to look at both sides. It's not easy to smoke mixed cigarettes. I also have to work as a car mechanic."
"So much nonsense!" Xu Siqi smiled and gave Zheng Zheng a false kick.
After he solemnly left the door, Xu Siqi immediately moved a chair, placed the green bricks on it, and jumped on it with a slight jump.
From No. 103 to the entrance of the alley, I also had to open the door to look for cigarettes and check the left and right tires on the back of the car. I will not be able to come back for another three to five minutes.
Not to mention the patrolman at the door. He is responsible for guarding the door. Without Xu Siqi's order, he will never dare to leave his post without permission.
To put it bluntly, even if someone accidentally bumps into you, there is nothing wrong with it.
Xu Siqi came to Fang Yongyan's house mainly to look for clues, so that no matter what he was doing, he would not arouse others' suspicion.
