To put it another way, if you are a monitor, there is something wrong with the person you monitor. And you have been seeing him for a while, and suddenly a few food delivery guys come to his house. Even if you are a layman, you will definitely be suspicious.
So Fan Keqin took advantage of this psychology. However, he watched for a while and saw that the two delivery guys might have been knocking on the door for a while, but no one opened the door, so he walked down. When passing the corridor window on the third floor, Fan Keqin could clearly see that the two waiters were talking to each other and having fun. It was obvious that no one opened the door and they were complaining about the person who called to place an order.
But other than that, I haven't seen anything else. However, Fan Keqin was not careless. The two waiters who had been watching the restaurant appeared at the window on the second floor, then walked out of the unit door and started to return along the original road.
Fan Keqin saw that they were about to walk through the doorway formed between the buildings. When they completely walked out of the yard, he still didn't see anyone coming out to follow them.
Fan Keqin stopped waiting and quickly came downstairs, following leisurely and far away from behind. The main thing was that he was observing whether there were tails behind the two shop assistants.
However, after he followed the two restaurant guys and returned to Wugu Restaurant, he still didn't find any tail. Fan Keqin was worried, so he found a secret location, observed it for a while, and made sure there was no tail before returning.
After returning to the residential building, Fan Keqin was still not in a hurry, but entered other corridors again. Through the corridor window, I observed the situation for about half an hour. But nothing happened.
Very good, this is a good sign. Fan Keqin waited no longer and came out again. This time he no longer made any tentative moves and directly entered the unit door of Li Tianye's house.
Quickly going up to the third floor, Fan Keqin lay down at the door of Li Tianye's house and listened. There was no movement at all inside. Then he stopped for any movement in the corridor and took out the prepared lock-picking tools from his pocket, two small iron bars with curved hooks.
Soon, Fan Keqin gently opened the door of Li Tianye's house. He still listened for a long time, but there was still no movement, so this time he carefully but thoroughly pushed the door open.
Then Fan Keqin stepped in and the first thing that came into view was the porch. This porch is not big either, only about three meters in length, and there is a coat rack next to it. There is an umbrella and two pieces of clothing hanging on the hook above the coat rack. Under the coat rack was a shoe cabinet. Fan Keqin looked up and down without touching the clothes, but looked inside the shoe cabinet. Well, there were two pairs of shoes in it.
The shoes were polished very clean, but they may not have been polished for a long time or several days, so a little bit of dust naturally fell on the shoes.
Fan Keqin looked at the upper of the shoe very carefully. The dust was really very small. It was just a very thin layer. If you didn't even notice, you would think it was clean. You can only see it at a very close distance. Um! These two pairs of shoes should have been untouched. If they were left here after being cleaned and dusted for a few days, they should be almost like this. If someone moves behind you, there will still be inconspicuous traces of dust on the shoes.
Fan Keqin bent down again and used his excellent physical coordination. Although he did not actually put his hands on the ground, his face was very close to the ground. He tilted his head and took a closer look at the situation on the porch floor.
In fact, dust is everywhere, it’s just a little bit. Well, the results of observation are quite good. There were no traces of dust on the ground, indicating that no one had entered the house in the past few days. The dust is basically the same as the upper, and it is in a state where you can't see anything unless you look closely. This shows that the owner of this room had cleaned it some time before leaving.
As for whether it was because someone came in to search after Li Tianye disappeared and then cleaned it to cover up the traces, it is still unclear.
Speaking of time, in fact, this kind of observation, even with Fan Keqin's eyesight, would take a long time on the ground with very little dust. He watched quietly for several minutes, observing the ground piece by piece and comparing it back and forth to confirm the information.
After reading this, Fan Keqin stepped in. He is not worried now that someone will be like him and will see him the same way when he comes in later. This is because he changed into a complete set of clothes, including shoes. The shoes he is wearing now are also newly bought, and they are still flat shoes. Even if someone does come after him, and uses the same observation method as himself to check the situation, at most he will only be able to tell that someone has been there with flat shoes. It's really impossible to see the rest of the information.
Fan Keqin walked in very slowly, observing the walls on both sides of the porch and even the ceiling as he walked. But he just held back a glance at the ceiling and was done. This is due to Fan Keqin's rigorous character. He also knows that even if what happened in the house before, there is very, very little information on the ceiling.
Unless there was an extremely fierce fight before, for example, a stick knocked out the brains of a person, and then blood sprayed everywhere, it might splash on the ceiling. A very intense situation like this is possible. In the remaining cases, there are traces on the ceiling, which are very, very rare.
So Fan Keqin just took a look. However, at this glance, Fan Keqin discovered a small black spot on the top of the ceiling. It's just a small black spot that ordinary people may not be able to spot if they don't pay attention, even if they walk on this porch dozens of times.
Fan Keqin immediately stopped and looked up carefully. It turned out that this little black spot was a little bit of blood. Very, very little blood.
This blood stain still has a little trailing tail, like a tadpole. But it didn't look like splattered blood, because the walls on both sides of the porch were painted white. And at first glance, it seems that it has been painted for at least a year and is not new. If there is blood on every touch of the sky, what kind of injury is this? There was no blood at all on the walls on both sides, just a small splash on the ceiling? This possibility cannot be said to be impossible, but it is simply too low.
However, Fan Keqin observed for a while and came to a conclusion...
