To put it another way, if you are a monitor, there is something wrong with the person you are monitoring. And you have been seeing him for a while, and suddenly some food delivery guys come to his house. Even if you are an outsider, you will definitely know how to do it.

Doubt it.

So Fan Keqin took advantage of this psychology. However, he looked for a while and saw that the two delivery guys may have been knocking on the door for a long time, but no one opened the door, so he walked down. After passing the third floor

Fan Keqin could clearly see the two waiters talking to each other at the corridor window. They were obviously complaining about the person who called to place an order because no one opened the door.

But other than that, I didn't see anything else. However, Fan Keqin didn't take care of it. He kept watching the two restaurant guys, appeared at the window on the second floor, and then walked away from the unit door.

Come out and start back along the original path.

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 at a leisurely pace from a distance. The main thing was that he was observing the two shop assistants to see if there were any tails behind them.

However, after he followed the two restaurant guys and returned to Wugu Restaurant, he still didn't find any tail. Fan Keqin was not worried, so he found a secret location and observed for a while, confirming that there was no tail.

Then he went back.

After returning to the residential building, Fan Keqin was still not in a hurry, but entered other corridors again. Through the corridor window, he observed the situation for about half an hour. But nothing happened.

Very good, this is a good sign. Fan Keqin stopped waiting and came out again. This time he did not make any tentative moves and directly entered the unit door of Li Tianye's house.

Quickly reaching the third floor, Fan Keqin lay down at the door of Li Tianye's house. After listening, there was no movement at all. Then he stopped for any movement in the corridor and took out the lock-picking tools prepared in advance from his pocket.

, two small iron bars with curved hooks.

Soon, Fan Keqin gently opened the door of Li Tianye's house. He listened for a long time, but there was still no movement, so this time he pushed the door open carefully but thoroughly.

Then Fan Keqin took a step and walked in. The first thing that came into view was the porch. The porch was not big, only about three meters long. There was a coat rack next to it. There was an umbrella hanging on the hook on the coat rack.

, two pieces of clothes. 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 have been wiped very clean, but they may not have been wiped 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, just a very thin layer. If you didn't even notice it, you would think it was clean. You can only see it if you are very close. Hmm!

These two pairs of shoes should have not been touched by anyone. If they were left here after being wiped and dusted for a few days, they should look like this. If someone moved behind them, the dust on the shoes would still be there.

Are there any noticeable marks?

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 the observation are still pretty good. There is no trace of dust on the ground, which means that it is indeed true in the past few days and no one has entered it since then. And the dust

It's basically the same as the upper, and it's 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 someone came in to search after Li Tianye disappeared and then cleaned it to cover up 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 to observe the ground with very little dust. He looked quietly for several minutes, observing the ground bit by bit, piece by piece.

Only by comparing back and forth can you confirm this information.

After reading this, Fan Keqin stepped in. He is not worried that someone will look the same as him now, and they will do the same when he comes in later. This is because he has changed a complete set of clothes, including shoes. The shoes he is wearing now

, they are also newly bought, and they are flat shoes. Even if someone does come after him and use the same observation method to check the situation, at most they can only tell that someone has been in the flat shoes. The rest of the information, then

It's really impossible to tell.

Fan Keqin walked in very slowly. As he walked, he looked at the walls on both sides of the porch and even the ceiling. But he just held back a glance at the ceiling. This was due to Fan Keqin's rigorous character. He also knew that even the previous house

There is very, very little information that can be found on the ceiling about what happened inside.

Unless there was an extremely fierce fight before, for example, a stick knocked out the brains of a person, and then the blood sprayed everywhere, it might splash on the ceiling. Similar to this very intense situation

, is possible. In other 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 ceiling. Even ordinary people, if they don't pay attention, may not be able to find it even if they walk around the porch dozens of times.

A small black dot.

Fan Keqin immediately stopped and looked up carefully. It turned out that this little black spot was a little bit of blood. A very, very small bit of blood.

This blood stain still has a little trailing tail, like a tadpole. But it doesn't look like a splatter of blood, because the walls on both sides of the porch are painted white. And at first glance, it seems that at least one of them has been painted.

The old white is not new. If there are blood stains on the sky, what kind of injury is there? There is no blood at all on the walls on both sides, just a small splash on the ceiling? This possibility cannot be

I would say no, but it is simply too low.
