Having money and potential can increase the probability of safe passage through the wilderness and ensuring safety to the greatest extent, but this does not mean that people without money and power cannot drive through the wilderness.

Evolver is the biggest variable here.

"Gu Yunxi, check immediately when he finally appeared outside Xihe City and when he first appeared in Xihe City."

Gu Yunxi responded, and then a crackling sound of keyboard typing came from his phone.

After a moment, Gu Yunxi Road said: "I found it, but it's worthless. This guy has been in Ulan City before October 3rd. He has no trace for the next half month, and he arrived in Xihe City on October 21st."

"September...eighteen days..."

Lu Fang murmured.

He was a little confused. The case happened three months ago, but Lu Qing had only been to Xihe City for more than ten days.

It can't be said that the disappearance of the jade bracelet has something to do with Lu Qing, right? This is too far-fetched.

But if it has nothing to do with Lu Qing, how can the system explain the prompts? Why is he following Wang Fang now?

There must be something tricky here.

However, you can not worry about this issue for the time being. The most important thing now is to figure out the identity and purpose of this guy.

The distance between Ulan City and Xihe City is nearly 3,000 kilometers. If the journey goes smoothly, you can arrive in about two days.

But this guy has no track for more than half a month. What does this mean?

Lu Fang was embarrassed to find that nothing could explain.

"Check the records of all private jets entering and leaving Xihe City during that period, and check all foreign vehicles entering Xihe City during this period."

"Is this... the workload too much?"

Lu Fang said calmly: "Isn't handling a case just looking for a needle in a haystack?"

"That depends on whether it's worth it?" Gu Yunxi said helplessly, "We have something on hand now, and I'm afraid we don't have much time. Which case do you want to investigate?"

"A case of robbery was rejected by the prosecution because of some defects in the amount involved."

"That's it?" Gu Yunxi was a little surprised. "It's better to find this thing clearly. If you can't find it clearly, there is nothing you can do. As long as the main crime facts are clear, there is no need to put too much energy on it."

Lu Fang said seriously: "If the suspect is involved in an evolutionary party, he cannot take it lightly."

"..." After a few breaths, Gu Yunxi Road, "Okay! I'll check it for you."

Lu Fang said: "I'll come back and check it out myself! I'm more efficient."

Gu Yunxi was a little angry. Is he disliked?

...

Lu Fang asked Xiaojun to continue watching Wang Fang, and he took the subway back to his unit by himself.

Although Lu Fang really wanted to go to work directly, it was already off work and the canteen was already open. Lu Fang couldn't help but get into the canteen.

After eating, Lu Fang entered his office with pride.

Data comparison is already familiar to Lu Fang, but the data comparison this time is a bit troublesome.

Instead of starting the operation immediately, he thought about how to troubleshoot.

When a large amount of data gathers together, how to find what is valuable to you is also a skill-based approach.

Lu Fang made a little weighing and first eliminated the possibility of fixed-wing aircraft.

It is normal that fixed-wing aircraft must enter the airport. Even if there is no ticket purchase record when taking a private plane, the face camera does not matter whether you buy a ticket or not.

Moreover, according to the current management regulations, except for the shuttle bus inside the airport, other foreign vehicles are not allowed to enter the airport, so this also blocks the possibility of taking the bus directly after getting off the plane.

However, based on the information Gu Yunxi just found that Lu Qing appeared in Xihe City, not near the airport.

Helicopters are not easy to rule out.

Many buildings have helicopter takeoff and landing floors.

After careful consideration, Lu Fang believed that the other party's possibility of riding in a helicopter was extremely low.

Helicopters fly across cities, and refueling is a difficult problem.

And the car is much simpler. On intercity highways, there are self-service battery replacement points at every distance.

Nowadays, all electric vehicles use modular batteries. When they are out of power, just go to the replacement point to take out the battery and replace it. It is faster than refueling.

It can be said that the only thing that needs to be considered when traveling on a self-driving tour is safety issues.

To be more relaxed, it is a probability issue.

Relatively speaking, the chance of dying from the city by driving is not that high, and only more than 100,000 people die every year.

If you think about the number of people who died in traffic accidents every year in your previous life, you will know that this number is indeed not high.

Xihe City is too large, with a large city with a population of more than 20 million, and the population flow between other cities is quite large.

Although most people choose to take the high-speed rail or take the plane, there are still some people who choose to drive by themselves for one reason or another.

Lu Fang first checked the data of all vehicles entering and leaving the city during this period, and the total number of data displayed in front of Lu Fang was 1.22 million.

This number is even greater than Lu Fang expected.

It is equivalent to about 70,000 or 80,000 vehicles entering and leaving the city every day. After a comparison, there must be about 40,000 vehicles leaving the city.

Later, Lu Fang ruled out the vehicles that had already had traffic trajectories in Xihe City some time before July 3, and the number suddenly dropped to 170,000.

This shows that vehicles moving across cities account for about half of the vehicles entering the city every day.

The number of vehicles entering the city every day is about 5,000.

In the previous life, even in a small county town, there were far more than this number of vehicles moving across cities every day.

But here, Lu Fang had to sigh, "There are indeed many people who are not afraid of death."

Next is the highlight, how to find suspicious ones from these vehicles entering the city.

This depends on the data analysis model.

If Lu Qing did not change the car in the middle of the way, then the car must have driven from Ulan City.

Just compare the tens of thousands of data that have been screened with the data in Ulan City.

As a result, it came out soon and there were dozens of cars driven from Ulan City.

After simple screening, such as the time when the vehicle leaves Ulan City, all of these vehicles have been eliminated.

"I changed my car halfway through!"

Lu Fang had a headache.

Changing a car is very troublesome because you can't be sure how many times this guy has changed.

Although you can still find this car by thinking from a strict time and space dimension, it is a real needle in a haystack.

Lu Fang would rather screen more than 80,000 cars one by one than do that.

In this case, Lu Fang had to rethink his investigation direction.

Just handle the case, that's it.

You can't expect every road to have results, nor can you just go through an alley without getting out of it.

The reason why he had asked Lu Qing to go to Xihe City before was that he wanted to pry open his possible hidden identity through transportation, and then use it to figure out his purpose of following Wang Fang.

As long as this line can provide slightly strong evidence, even if it is just some directive clues, Lu Fang dares to arrest people directly.

But now this road is obviously not working.

"It is obviously not very suitable to directly take someone right now, so you still have to follow him."

"Since this bastard..."

Lu Fang's thoughts had just flashed through his mind, and a scream of a little falcon warning suddenly sounded in his mind.

His consciousness immediately switched to Xiaoxiao. With the help of Xiaoxiao's vision, the scene in front of him made Lu Fang feel nervous.

It's dark now, Wang Fang has returned to her community and is currently walking into the elevator.

And less than three meters behind her, there was also a person walking calmly.

This person is the fat man Lu Qing whom Lu Fang was paying attention to before.

"This guy is not kind!"

Lu Fang made a judgment immediately.

If Lu Qing had made irreversible plans to Wang Fang at this time and brought irreparable harm, he would definitely be uneasy.

Without any hesitation, Lu Fang stood up and rushed to the duty room.

Ma Lu, who is on duty today, is sitting in the duty room at this moment, a little bored, perhaps praying that there will be no major police incident today.

Suddenly, a hand stretched out from behind and grabbed a car key on the table.

"I have to get off."

When Ma Lu turned around, there was no shadow behind him.
