In fact, Conan's reliance is very simple, that is, this is an abandoned warehouse, but almost no one comes to the warehouse, since few people come, since no one has come for a long time, then it must have been full of dust, at this time, if someone suddenly moves inside, it will leave very obvious traces, that is, Conan only needs to find those places where there are traces of dust. Unless this gangster is a monkey reincarnated, he will definitely not run around in a dusty old warehouse, leaving a lot of traces, which means that Conan's workload is actually very small.

"Hey, Tifa, what the hell is the pit you dug for me? You deliberately avoided this question when you were at the school gate before, but you don't expect to be fooled around this way. Seeing that Conan was about to step into the warehouse, Tifa didn't have any obstruction, and even from the time he came to school until now, Tifa didn't obstruct and interfere with Conan, which made Conan feel a little worried all the time, for fear that Tifa would suddenly get nervous, and now it was about to start the most important link, Tifa still didn't have any suspicious moves, Conan hesitated a little, could it be that the pit that Tifa dug was in the warehouse?

"Would you believe me if I said I wasn't going to trick you at all?" Tifa bent down, brought her delicate lips in front of Conan, and suddenly said in a very gentle voice.

"Huh-you! What do you want!? Tifa's attitude suddenly became very kind, which not only did not make Conan feel comfortable and warm, but made him feel as if he had suddenly seen a ghost. Looking at Tifa's two delicate lips, Conan felt that these were simply the two fangs of a viper. And the sweet smell that erupted between Tifa's two lip flaps. It's like a serpent's forked letter. It makes Conan feel creepy. While screaming, Conan instinctively jumped back, instantly widening the distance between him and Tifa, although the distance was widened, but until he figured out the reason for Tifa's sudden change of attitude, Conan did not dare to contact Tifa.

"Bastard! I'm that scary!? Conan's frightened and vigilant reaction made Tifa stunned for a moment, and then Tifa's originally gentle expression suddenly changed, and his right hand clenched into a fist. An iron fist smashed into Conan's brain precisely in the midst of Conan's frightened eyes and the action that he wanted to dodge but couldn't dodge, as if he had a satellite positioning.

"Ah!!h Although Conan was screaming, he couldn't help but breathe a sigh of relief in his heart, this kind of violent behavior was Tifa's normal reaction, Tifa suddenly spoke in such a gentle tone, he really didn't feel comfortable. However, Tifa is usually so violent, and the person she likes in the future may be tragic, and I don't know if Tifa will be so violent when facing the person she likes. I hope not. Unconsciously, Conan couldn't help but think crookedly again.

Inside the warehouse.

"There's a stainless steel baseball bat here." Tifa picks up a baseball bat that he had dropped the night before, one of the two clues. Looking at the tip of the baseball bat, Tifa's eyes narrowed slightly. Raised the baseball bat, knocked the cement floor, a crisp sound of "bang", the inferior and long-term unmaintained cement floor immediately appeared a very obvious depression, and the baseball bat and the ground impact part also appeared a flat area, looking at the traces of the impact, Tifa couldn't help but be stunned, how could this baseball bat be so soft? Obviously, I only used a small amount of strength.

"Stupid, this baseball bat is not made of stainless steel, but of aluminum. There are three most common materials for baseballs, which are birch, maple and aluminum. Birch is harder, maple is tougher, and soft baseball is made of aluminum. The density of iron is close to three times that of aluminum, and if it is such a large baseball bat made of stainless steel, I am afraid that few people will use it, and although stainless steel has a low carbon content, it will not be so soft. Conan also saw the flattening mark on the baseball bat when Tifa hit the ground.

Finally seized the opportunity to preach to Tifa, Conan immediately croaked and said a lot, and before he finished speaking, Conan jumped back directly, and at the same time covered his brain, preventing Tifa's fierce iron fist attack at any time.

"There is no dust on this baseball bat, apparently it just appeared in this warehouse, and the kidnapping happened the night before, so although the kidnappers also like to play baseball, and they still play baseball at this school, it is not certain that this baseball bat must have been the kidnapper's, and it is not certain that the kidnappers have been here." Rubbing his fingers lightly on the baseball bat, Tifa looked at the smooth fingers.

"Humph! Sling the bull! Even if there was still a little bit of dust, it was all gone under the violent impact just now. Conan gave Tifa a fierce look, he was very sure, one hundred percent sure, that Tifa was absolutely intentional just now.

In such an old warehouse, even if the baseball bat is only left for a day, there will be a thin layer of dust on it, but Tifa just hit the ground with the baseball bat, and the violent collision will make the metal baseball bat enter the high-frequency and small amplitude vibration, so as to shake off all the dust on the surface. This method is only suitable for a little bit of dust, and is not very useful if the baseball bat is already covered with dust. The reason why Tifa did this was to prevent the Connanme guò baseball bat from judging whether it was lost by the gangsters the night before, so that it could not be consistent with the kidnapping, and therefore could not determine whether the gangsters had been here.

"The front end of the baseball bat still has some green, and the other parts are very clean, which means that the owner of the baseball bat often wipes the baseball bat, and the green on the front end is newly stained, from the green has faded a little, but it has not completely faded from the analysis, the baseball bat has only been lost for a few days. That is, it is quite certain that this baseball bat belongs to the gangsters, and the gangsters used to stay here. It's just that later, the gangster was somebody who didn't know where to go. Conan said, when talking about "someone", Conan glanced at Tifa meaningfully, and it seemed that the "someone" he was referring to was Tifa.

"That's right, little ghost, you've found out." Tifa rubbed Conan's brain fiercely with some annoyance, this special green color was discovered by Tifa when he got the baseball bat just now, compared to the clue of dust, the green clue is undoubtedly more hidden, so Tifa will hit the baseball bat on the cement floor, remove all the dust on it, and completely eliminate the clue of dust, but unfortunately the little trick that Tifa came up with temporarily was hidden in the face of Conan's keen insight, If Tifa's behavior of hitting the baseball bat was not seen or heard by Conan, since he saw it, Conan was in a state of doubt, so he naturally had to take a good look at the baseball bat, and naturally think about why Tifa did it, so it would not be surprising to find that special greenery. Tifa is a typical clever but clever mistake, there is no silver three hundred taels here.

"Since the gangsters have indeed been here, then these footprints should be the gangsters'." Conan bent down and looked at a footprint with intricate patterns, and it was a very new footprint at first glance. The reason why this footprint is considered new is that the compacted surface of the dust of the footprint is very flat and there is no dust that falls again.

Now that the two of them know who the gangster is, the clues collected now should be about where the gangster lives, so Conan doesn't pay any attention to the originally extremely useful clue of footprints. In other cases, a footprint can provide information such as gender, age, height, weight, personality, and personal habits, after all, the footprints left by people in different situations are completely different, and just one footprint can exclude the vast majority of people.

In fact, these footprints are not completely useless. Now that we know that there are no shoes or anything like that in the storage box, and that normal people don't run around with a pair of shoes, we can be sure that the gangsters have been wearing a pair of shoes all along. Normal people do not deliberately pay attention to the comfort of shoes if they are only for special and short-term purposes, such as to attend special occasions, but if they are going to wear them for a long time and do a lot of activities, the comfort of shoes is very important. Tifa slid his fingertips lightly over the footprints.

"Different types of shoes, suitable for different occasions and different walking distances, walking on the walking path of the city in sandals or hiking boots is an absolute disaster for the wearer himself, and the type of shoes can determine the radius of the gangster's activity, and you can also find out where the gangster bought the shoes, and then determine the radius of the area where the gangster is located. These footprints, if you look closely, you will find that there are a little signs of slippage on the traces, which indicates that the sole of this shoe has a certain hardness, and the foot bounced very slightly at the moment of landing, and the gangster should not be wearing shoes with low-strength soles. Conan took a closer look at the footprints.

"In every detail of the footprints, there is a slight blur, which is a phenomenon of uneven force in various parts of the contact surface, and it is obvious that the contact surface has been slightly deformed. Regardless of whether the cement floor is inferior or not, the hardness is relatively large, that is to say, it should be the shoes themselves that are deformed, so I estimate that the shoes worn by the gangsters should not be high-strength soles, but are estimated to be medium-strength. Tifa and Conan looked at it from different angles, but came to a similar conclusion, and the two of them worked together to lock in the approximate range of the shoe. (To be continued......)
