"I guess so. When the car came, it may have walked through a piece of yellow earth, but after passing through the yellow earth, it went on the hardened road of the city, so most of the loess on the tires was thrown off. But after coming here, because the tire pressure changed too much when it stopped, the loess that remained on the tires fell again. There's no way to measure the wheel base and wheelbase? Long Fei said.

The distance between the centerline of the two front wheels of the car is called the front wheel track, and the distance between the center lines of the two rear wheels is called the rear wheel track. The so-called wheelbase is the distance between the front and rear axles. They are all important parameters of the car.

Long Fei wants to roughly judge the type of car by the two parameters of wheel base and wheelbase, so the more accurate these two parameters, the better, if measured with steps, it is too inaccurate.

Long Fei didn't expect the two of them to carry a meter ruler with them, and was proposing to buy a steel tape measure, but heard Mo Zixing say: "Of course there is a way to achieve accurate measurement." ”

As he spoke, Mo Shaoxing took out his mobile phone and put it on a handful of loess. Long Fei found that a red light was emitted from the camera of Mo Shaoxing's mobile phone, shining on a pinch of loess closer to the mobile phone, and when the small red light point shone on the loess, Mo Shaoxing reported a data: "Assuming that the other party drove the car from that direction, and then braked sharply to cause the loess that was originally stuck to the tire to fall off, then now I should be measuring the front wheel track, and the data is 1825 mm." ”

Then Mo Zixing turned the phone in one direction, and the red light emitted by the phone was directed at a pinch of loess far away from the phone, and said: "This is the wheelbase of the front and rear axles, 3320 mm." ”

After finishing speaking, Mo Zixing came to the back two handfuls of loess, measured the rear wheel track, and said: "The rear wheel track is 1830." Since we only infer the position of the tire based on the position of the loess and cannot find the center line of the tire, this set of data is very watery. And I'm guessing that the front and rear tracks of this car may be the same. Instead of the front and rear tracks being different, as we measured. ”

"That's enough. This set of data is enough to show that this is a very wide off-road vehicle, or an urban SUV. Ordinary sedans simply don't have such a wide track! If my guess is correct, last night's master drove the car and climbed into Trump's hospital room with a flying tiger claw, stunned the little nurse, and got Trump away. Long Fei said confidently.

"What about the four police officers waiting outside the door of the ward? What role did they play? Song Ziyue asked subconsciously.

"Two cases. One is that they really don't know, and when the other party comes, they all go to sleep, or they don't hear each other's movements in the ward at all. In the second case, the other party and the police are in the same group at all! What the four policemen said was a lie to us. Long Fei said with a head on his head.

"It seems to make sense. But how do you know that this car is the one that stole Trump? Isn't it someone else's car? Mo Zixing asked again.

"Two pieces of evidence, one is that this is not a parking lot, and there is no parking space, so under normal circumstances, no one would park here. Of course, this alone is not enough to explain anything, after all, there are too many illegal parking people in this world. Another point is that none of these four handfuls of soil have been trampled on, and this place is a densely populated place. If the car had been parked here yesterday afternoon or in the first half of the night, it would have been trampled on a long time ago! If we come later this morning, I'm afraid we will be trampled on. ”

As Long Fei spoke, he pinched a handful of dirt into his hand and rubbed it, and said: "The dew last night was very heavy, but the soil was only slightly wet, so I can not only conclude that this car drove in the second half of the night, but when it came, it was already past the time period when the dew was at its worst!" The car most likely came after four in the morning! ”

Song Ziyue and Mo Zixing couldn't help but show a look of surprise on their faces, before Long Fei judged that Trump was stolen by someone through the scratches on his shoes and windowsill, not that he had escaped, and the two of them were not too surprised. After all, if they found these clues, they could come to the same judgment.

But now Long Fei was so surprised that he had deduced so much information just by four handfuls of loess! Long Fei is already at the level of a professional detective.

Long Fei looked at the strange expressions on the faces of the two of them, and couldn't help but say, "What? Don't you believe me? ”

Song Ziyue said with a smile: "I believe it, I believe it too much!" Long Fei, are you a doctor or a detective? How do I feel like you're more of a detective now? ”

Long Fei smiled and said, "Hehe, if a person has been on the verge of death for a long time, he will naturally be able to master some skills that others can't master. ”

When Long Fei took the Shenlong team to carry out missions everywhere in country X to earn funds for the refugee camp, I don't know how many times he was hunted down and killed! Long Fei relied on his own accurate judgment and careful thinking to lead the Shenlong Special Operations Team to put the Grim Reaper to death again and again!

Song Ziyue and Mo Zixing were also used to crawling on the edge of life and death, so they were deeply touched by Long Fei's words, nodded again and again, and said, "That's right!" Reasonable! I can't imagine that Brother Long is not only a doctor, but also a detective, and a philosopher! ”

"Actually, you're all wrong. To be precise, I'm supposed to be an entrepreneur! Oh, Mo Shao, what brand is your phone? Seems powerful? Long Fei said with a smile.

Being in the mood to joke no matter what the situation is is also a sign of power.

"Spy product! It is not available on the market. Mo Shaoxing also said with a smile.

"I'm kind of an organizationist, right? Why didn't you get me a phone like this? Long Fei said a little depressed.

"No, Long Fei, you can only count half now, and when you really count one, of course you have what we have." Song Ziyue said.

Three people were talking, and several police officers walked up to them. It turned out that the Hanoi police got the news and sent someone to rush over. Long Fei and the three of them immediately put away the expressions they had just joked about and replaced them with serious expressions.

"Did you find anything out of the three?" A very short policeman looked at Long Fei and the three asked.

"No, we didn't find anything. Comrade police, Trump was caught by us! Therefore, we must bring him back to China, and I hope you can get him back soon! Song Ziyue said solemnly.

"We're definitely going to get Trump back! But one thing I have to tell you clearly is that you caught Trump, though. But he did something illegal in our country, and we also paid a huge price to arrest Trump, so he must accept the legal punishment of our country! The short officer said.

Long Fei and the three of them glanced at each other, and then Long Fei said, "Okay, let's put this matter aside for a while." Whoever Trump ends up handing over first, the most important thing right now is to find him first, isn't it? ”

"That's true!" The short policeman looked at Long Fei and the three of them and said.

"So what are you waiting for? Why don't you hurry up and find someone? We need to report this to our superiors, so let's take our leave! Song Ziyue said unceremoniously.

The short policeman saw that Long Fei and the three of them didn't seem to have found anything, so he had to turn around and walk into the ward building with a few of his subordinates.

If someone else had spoken to him like this, he would have asked his subordinates to arrest them, but he wouldn't dare in the face of Long Fei and the others!

After the figures of several Vietnamese policemen completely disappeared into the ward building, Mo Zixing whispered: "Do you think Trump was hidden by the police?" ”

"Possibly. But even the police, not Hanoi, at least the armed police. In fact, I suspect that it was the Vietnamese military who made the move. Let's go, whoever he is, we're going to find them! Now let's figure out where this car got this loess from. Then find a way to find the car! Long Fei said.

As Long Fei spoke, he walked towards the gate of the hospital. As Long Fei walked, he looked around at the cameras above his head, and he found that from the parking point to the gate, except for the two cameras at the gate, there was not a single camera installed along the way! Under the two cameras at the gate, there are two maintenance workers in overalls.

Long Fei could also think with his toes that the camera here must have been broken!

The entrance of the hospital is the only way to get in and out of the hospital, and if this camera is not broken, the car will definitely leave a video record!

Long Fei went over to ask and found out that the camera had just been broken since last night! As for how it was broken, it is unknown.

Long Fei originally wanted to get a little more news from the security guard at the door, but was told by the security guard at the door that the security guard on the night shift had already left work, and he didn't know anything about the shift just now!

The security guard who had just taken over also told Long Fei that even if they found the security guard on night duty, it would be impossible for him to ask what kind of cars came to the hospital after 4 o'clock in the morning last night. Because it was Lao Wang who worked the night shift last night, Lao Wang is called a sleepy insect, and he is sleepy when he goes to work during the day, let alone at night!

Not to mention just driving into a car, even driving into a tank, he still sleeps with him!

The security guard probably had some hatred for Hua, and when he saw that Long Fei and the three of them were Chinese, he spoke a little stiffly. Long Fei had a bad impression of him, he originally wanted to ask the security guard, where the road was being built nearby, exposing the loess underground, or where there was loess underground, but now he didn't want to ask. It's good to go out to the hospital and ask others, why do you have to ask this security guard like a dead star?

Besides, Long Fei didn't plan to get something useful from the security guard, if the other party could easily leave a handle here with the security guard, he wouldn't be called a master, he should be called a waste wood. Long Fei came over to ask, that is, with the psychology of having dates and not hitting a shot, since he couldn't hit dates, he didn't bother to go to the security guard on night duty.

Song Ziyue and Mo Zixing also felt that it was useless to find the security guard on night duty, so no one mentioned this stubble.

Out of the hospital gate is an east-west, two-way four-lane street. There was a fruit stall on the sidewalk across the street, set up by an old man in his seventies, with gray hair, a face of vicissitudes, and a thousand ravines on his forehead, each of which seemed to be sealed with countless stories. The old man wore a hat, gray homespun clothes, and cheap plastic sandals on his feet, like a peasant in the late eighties.

The old man looked around, looking uneasy. It's as if he's afraid that an enemy will come and cut him with a knife in the next moment!
