While joking, the two went back to Qingyu Villa all the way, and after a simple meal, Ding Fan went straight to the basement.

Seriously, Victor found a lot in Ada's room tonight.

I heard that the whole wall has been hollowed out, and I don't know how many things are placed in the bottles and cans, and I don't know what they are used for, anyway, there are a lot of poisonous things, and I don't have time to distinguish them, so I will bring them back and see them first.

Fortunately, in this regard, Ding Fan also has masters under him, and Leon is a master in this area, and if these things are handed over to him, it won't take long to figure out what these things are for.

In this regard, Ding Fan still believes in his gang very much, but it will take a little time, and it is estimated that tonight, Leon will not want to sleep.

Maybe scientists have this kind of character, they have something in their hands that they don't know what it is, and they always want to figure it out, otherwise they don't want to sleep at all.

However, what was found in Ada's room was not only this little thing, but there were also some other things in the room after being searched.

For example, the card that I don't know where Xiaoyin found it, only the words 'Perfume Hall' were written on it, and there was not a single word more.

Ordinary people don't know what this thing is, or Ding Fan just met Kong Jie and asked casually.

Only after this question did I know that this so-called perfume hall is actually just a local bathhouse.

Not to mention, there are really no people who know about this bathhouse, if it weren't for a local, explain it to him, I'm afraid that Ding Fan, a foreigner, may not be able to know this place.

But the problem is that Ding Fan is just a foreigner, and Ada is no longer just a foreigner, she should be regarded as a foreigner.

But she actually has such a card in her hand, obviously this card is not for publicity, otherwise there should be an address or phone number on it.

If you look at it this way, this so-called bathhouse should not be just a bathhouse, if it is just a façade selling dog meat with a sheep's head, no one will know what to do in private.

If you want to know this key question, you have to go there in person.

I just don't know where this place is, and whether it's a better place to find.

In addition to this card, Xiaoyin also found some tape in the room, this thing looks very ordinary, it can be bought in many places, and it is also used for a lot, and I don't know what this thing is used for for a while.

However, Xiaoyin felt that the tape didn't look special, but normal people wouldn't put so much tape at home.

When I opened the cabinet at that time, although there was not a lot of tape, there was a slightly vague mark on the corner of the cabinet, apparently there was a lot of tape in the cabinet before, but when I left, there was not much tape left, so the remaining two rolls were not taken away.

There are not many things in this room, mainly the things in the wall, Leon is still investigating at this time, and it is estimated that there will be no results in the short term, and it will be tomorrow morning at the earliest.

On the contrary, in the room where Ida was sniping Ding Fan on the other side, Xiaoyin found more things.

Two travel bags with most of the clothes inside.

The most important thing should be a passport that was accidentally found in the compartment of the travel bag.

This thing is more useful, judging from the photo above, it should be the identity that Ada is using now, but the authenticity of this passport is not clear for the time being.

In this regard, you need to ask Xiao Hei for help and check the information at the Immigration Department.

In addition, there are very few clues left by this Ida.

But Ding Fan always felt that this bag was a bit like she deliberately left it at the scene.

Maybe it was to cover up what she had left in the room, so she fired a shot at the time, and if she could kill herself, then everything would be fine.

If there are companions outside, they will also be attracted to the opposite room because of the gunshots.

In this way, it can be regarded as a shift in focus.

"These clothes are all domestic goods, not brought by her from abroad, from these clothes, there is no way to analyze where she came from!" Ding Fan held two women's clothes in his hand, and after a brief inspection, he casually threw them on the table.

Although he is not a businessman, his cousin is a businessman, and Chen Dalong has been doing well in the port city area over the years, and every time there is a new style of clothes, he will send him a few pieces to see.

He knows more about the internal structure of domestic clothing than anyone else, and he can see it at a glance.

The most critical point is that these clothes, Ding Fan can see, they are not worn at all.

There are obvious fold marks on every piece of clothing, which are generally professionally folded when they come out of the garment factory.

The two large bags of clothes come from three different production areas, and the folds and indentations on them are completely different.

But one thing is the same, the indentations are deliberately folded to make the shape of the garment stand out, which proves that the garment has not been worn before.

Because when anyone wears a piece of clothing, they will subconsciously pull the corners of the clothes apart, try to make the clothes on the body look more neat, and it will be more comfortable to wear.

But the creases on these clothes have not been touched, that is, the clothes were left on the scene as a completely deceptive thing.

"Since the clothes were deliberately left at the scene, then I don't think there is any need to investigate the passport!" Ding Fan just glanced at the passport in his hand, casually threw it on the two travel bags, but reached out and picked up the measuring tape on the table, as if thinking about something.

"Boss, are we all working in vain tonight!"

As soon as Xiao Yin heard that these things were deliberately left behind, her whole face immediately fell into praise.

But Ding Fan vaguely thought of the use of this kind of tape, but he was a little unsure for a while.

"This kind of tape is very common outside, and it has a lot of uses, and I have a forensic friend who sometimes has some of this kind of tape!" Ding Fan remembered that it was naturally Qin Lu, who had found this thing in her backpack before, and heard that it was used to collect fingerprints.

Duct tape can be used to collect fingerprints, so is it possible to use this thing to collect something else?

As soon as he thought of this, Ding Fan's mind seemed to be playing a movie, and he recalled all the objects in the house he had rented in Ida before, and from the moment he entered the door, every detail was recalled.

But he didn't think of anything noteworthy at the scene, even the trash can in the bathroom he had thought about, it had now been brought back, and although there were some incomplete fingerprints on it, there was nothing of noteworthiness.

As soon as he thought of this, Ding Fan felt a headache.

Obviously, it feels as if it is very close, but it always slips through his fingertips at the last moment, so that he has no way to grasp the feeling he wants.

Just when Ding Fan was about to give up, Ding Fan suddenly remembered a somewhat suspicious question.

That's the door to Ada's house!

He still remembers that when he cautiously rushed to Ada's house with someone and secretly opened the door with a paper clip, he was still a little curious, and in the entire building, it seemed that only the door of Ada's house was a metal security door that was replaced later.

It's a little different from other people's homes, and I thought that after all, a woman lives here, and it may be safer to change the door.

But now that I think about it, this door seems to be a little too clean, the room where Ida lives is not big, not to mention the sanitary conditions inside, she usually doesn't live here, but lives in the opposite room, only occasionally eats something here, and sleeps in the opposite house, by the way, monitoring the situation here.

The room is cluttered, why do you wipe the door so clean?

After looking at the roll of tape in his hand, Ding Fan understood it completely.

The metal security door seems to have been changed for security, but in fact, Ida should have chosen this door for the smoothness of the façade.

And this door is actually a message board that she has always contacted outside, and usually when she is not there, someone will write a message on the door with her finger.

When Ida returned, she would naturally check the specific position on the door, and then use the tape on her hand to wipe the message on the door.

This method is actually not new, and those agents outside the country often use this method.

However, some people later felt that this method was very restrictive and unsafe, so they directly replaced this method.

I didn't think that there were still people using it now, and they almost used this trick to deceive Ding Fan.

Ding Fan held the tape in his hand and handed it to Xiao Yin, telling him to run with Victor and bring back the clues left on the door.

Xiaoyin immediately called Victor, and the two hurried to the previous rental house.

More than an hour later, Xiaoyin and Victor rushed back from the city, came back with the previous roll of adhesive tape in their hands and said: "Boss, it's basically the same as you think, I arrived at the place, briefly checked the door frame, and found the residue of glue on it, along that position, with tape to extend things from above, but this time you are afraid to be disappointed, there is no text on it at all, but a lot of numbers on it, I don't know what it means!"

Ding Fan stretched out his hand to find the tape, and carefully checked the traces on it, which was really the same as what Xiaoyin said.

There wasn't much writing left on the door, just a large number of codes left on it.

If I'm not mistaken, this should be a set of ciphercodes, I don't know what this means, the root cause is because they don't have their codebook.

Just when Ding Fan was discussing the password with Xiaoyin and the others, Yan Liqiu ran down from above, came down with a thick document in his hand and said: "I found it, Li Minghai is the same person as you think, it's not simple at all, everyone underestimated him before, and for twenty years, hiding himself in the dust, it should be to soar into the sky!"
