The car has to make a big turn, which is a design feature to reduce the slope, but for Jiang Hang, who walks, he doesn't need to take a long detour along the road. He can simply climb up the steep slope that the car came down.

For most people, this might be dangerous, but for Jiang Hang, this amount of work wasn't even enough to warm him up.

Watching Jiang Hang traverse the steep slope with ease, Fujiwara Bunta, inside the car, asked Kiharu Yuno in the passenger seat with some curiosity, "Your boss is really skilled. Do detectives need such good skills nowadays?"

Jiang Hang dismantled the car door with his bare hands and so easily made his way up the steep slope. Has the detective industry evolved to this level now?

Upon hearing Fujiwara Bunta's question, Koharu Yuno's expression became slightly subtle: "After all, I often deal with criminals, so I need to master some basic self-defense techniques. Naturally, my fighting skills are a little better than the average person."

This was something Jiang Hang taught her: when facing strangers, speak in a way that is half-truth and half-lies, so that people cannot ascertain her full strength, in order to avoid any unexpected situations.

Bunta Fujiwara wasn't stupid, so he naturally wouldn't take Yoshino Kimura's evaluation too literally.

However, those who have never actually seen Jiang Hang make a move can never imagine the extent to which Jiang Hang can achieve his full power.

Jiang Hang quickly crossed the roadside guardrail and arrived at the actual crime scene.

Compared to the horrific scene below, the traces left here are much simpler.

The unpleasant smell of burning tires and the clearly visible tire tracks extending from the road before the turn to the gap in the guardrail all pointed to the fact that this case was not simple.

Jiang Hang looked at the tire tracks on the ground. There was no shortage of drifting enthusiasts in Akina Mountain who challenged this classic five-hairpin turn, so tire tracks left by vehicles drifting could be seen almost everywhere on the road.

However, most of these tire tracks were left before; there are only a few different tire tracks left from today until now.

The tire track looked nice, and the mark wasn't very obvious; it was clearly the trace that Fujiwara Bunta had just left.

He specializes in drifting, so he naturally chose the kind of tires that are very durable. In addition, he goes through corners at extremely high speeds, more than 100 kilometers per hour, which is not enough to leave very obvious drift marks on the ground.

Therefore, this one can naturally be eliminated.

The remaining two tire tracks, which appear to be deeper, extend towards the guardrail. The former tracks are particularly noticeable, clearly indicating that the person was braking and then being forcibly hit from behind, causing them to lose their balance.

These tire tracks are clearly the key part of this case.

Looking at the scene, Jiang Hang could almost instantly recreate what had just happened in his mind.

A man driving a black car, whose origins are unknown, was being chased by someone. Therefore, his driving speed was not slow. To be able to drive to the five hairpin bends after Fujiwara Bunta had finished descending the mountain without encountering Jiang Hang and Fujiwara Bunta, this speed was already considered relatively fast for a normal person.

However, this is also because the first half of Mount Akina does not have many consecutive curves, and the straight section is not short.

In short, the two of them drove all the way to Mount Akina after Fujiwara Bunta, and then drove at a steady pace all the way here. However, when they encountered a series of five hairpin bends, the former was driving a brand new car that had not been broken in, so for safety reasons, the man had to slow down.

It's estimated that when the car was going around the bend, the other car was probably only going around 3 or 40 kilometers per hour.

On the contrary, the driver of the car behind was much better, so when the other car slowed down, he caught up with it right there and drove the car in front off the cliff without hesitation.

"I remember that from the very beginning, there haven't been any cars with front-end damage driven down Mount Akina."

Jiang Hang has a great memory; if a car with a damaged front end passes by them, he will definitely notice it immediately.

If the car that caused the accident didn't go down the mountain, then it must have crashed into the car in front of it and then at most briefly checked the situation of the car in front of it before turning around and heading back up the same way to avoid being discovered.

Jiang Hang initially thought that this trip would be just a regular racing adventure and wouldn't involve any cases, so he didn't let Artaer scout outside but instead had him stay in his car.

Who knew that a case would actually occur?

Without a radar located high up, Jiang Hang could no longer easily ascertain the car's model and its current location as before.

However, even without Altaïr's help this time, it doesn't mean Jiang Hang is helpless.

Under his observation, some fragments at the scene quickly caught his attention.

Chapter 474: Chapter 470: My hacking skills were taught by Kung Fu Master

What Jiang Hang found were some dark blue paint fragments, which looked like paint scraped off when the two cars collided.

"So, it was a dark blue car that crashed this Mercedes off the cliff and then turned around and drove back?"

There were never any surveillance cameras installed in the area around Mount Akina. If there were, Takumi Fujiwara wouldn't have dared to drive without a license on this road for five or six years when he was only 13 years old, and he wouldn't have gone unnoticed until now.

Therefore, relying on surveillance is no longer an option.

As for reasoning?

To deduce the model of the car driven by the murderer from these paint fragments, unless the car's paint is an extremely rare limited edition, even if Sherlock Holmes were reincarnated, he wouldn't be able to figure out the car's model.

However, to be honest, this kind of case is not too difficult for Jiang Hang, since he already has quite a few clues.

The blue car, with obvious dents on the front, had been there for less than ten minutes since it crashed into the wrecked Mercedes and left the scene.

Because they left via the uphill road, their speed wouldn't have been too fast, and given the winding roads around Mount Akina, the murderer has only traveled a few kilometers in a straight line at most.

At such a short distance, although Altaïr couldn't be dispatched immediately, sending it to circle around in the sky would be enough to roughly determine the killer's current location.

Jiang Hang originally planned to act swiftly and decisively, since this kind of heinous crime, which seemed to be organized by a large group behind it, and the reward for the commission was usually quite good, and it wouldn't delay their original plans for tonight.

But just as he was about to return to his car to have Altaïr search for the murderer and take the fragments to Fujiwara Bunta, who had spent his life dealing with cars, to see if he could come up with anything, a phone call from Yamamura Misao made him temporarily put his plans on hold.

On the other end of the phone, Yamamura Misao excitedly said that he was currently in Shibukawa City, not far from Mount Akina, investigating a vehicle theft case with another police inspector. According to him, several luxury cars had been mysteriously stolen in Gunma Prefecture recently, and there was likely a professional gang behind it.

Gunma police haven't found any useful clues yet, but after hearing that a Mercedes-Benz with fake license plates had apparently crashed in Jianghang, Yamamura immediately said he would send people over right away.

Shibukawa is not far east of Akina Mountain, less than 20 kilometers away. A race car driver like Fujiwara Bunta could get there in ten minutes, but Yamamura Misao is a respectful and law-abiding policeman, so it would be good if he could get there in half an hour.

As for why Yamamura Misao was working in the Toushin Forest a few days ago, but came here again today, there's really nothing strange about it.

The Japanese police are directly under the jurisdiction of the National Police Agency, which is then further subdivided into police headquarters for each prefecture. The Metropolitan Police Department is the police headquarters of Tokyo.

Below that are the police stations in various urban districts of the county, roughly equivalent in status to public security sub-bureaus.

Further subdivided, there are the small police stations within the town, which are the most common type.

The rank of a police station chief who is transferred to another post is usually a police inspector or police inspector, while the rank of police commissioner is usually a police superintendent.

The regular police officers in the police stations are mostly junior officers in non-professional units. Unless they have committed some serious crime, the spur-of-the-money and career officers work at the police headquarters in various locations.

Each local police headquarters is responsible for all cases within its jurisdiction. For example, Inspector Megure, a police inspector in the Metropolitan Police Department, has to travel around Tokyo all day long.

From the city center to the remote mountains and wilderness, and even the small islands overseas, as long as a murder case occurs within the nominal jurisdiction of the Tokyo Police Department, Inspector Megure, the inspector of the First Investigation Division, must rush to the scene to conduct an investigation.

Yamamura Misao was in the same situation. Whenever a case occurred in Gunma Prefecture, as long as he was not far away, he could rush over to investigate after telling his superior.

In short, after learning that Yamamura Misao would be arriving soon to take over the case, Jiang Hang's thoughts changed somewhat.

For the past few days, Jiang Hang has been studying advanced criminal investigation techniques in the Tou Shen Forest, which he learned from the system's learning space over a long period of time from Shan Cun Cao. However, these techniques have not been of much use to him due to his cheat-like abilities.

To be fair, the elites in the Mountain Village group do indeed learn things very quickly.

Don't let his simple and honest appearance fool you; those who can pass Japan's top-tier civil service exams are all academic geniuses.

In areas involving theoretical knowledge and rote memorization, Yamamura Misao learned with almost no difficulty, especially in the field of computers, where he displayed a talent that even surprised Jiang Hang.

Yamamura Cao did obtain computer certificates during his university years. Although they were only basic computer languages ​​and the use of office software, his foundation was quite solid. His occasional ingenious ideas at that time also brought him many advantages.

If he hadn't chosen to become a policeman, he could definitely have become an excellent programmer. Now, under Jiang Hang's most scientific guidance, learning hacking techniques is not difficult for him at all.

It's important to know that the scientific development in this world is quite advanced, and the development of computers is much more advanced than in his previous life. Jiang Hang remembers that artificial intelligence and immersive virtual games appeared in the movie The Phantom of Baker Street.

As for Professor Agasa's amazing high-tech products, there's no need to mention them.

However, in contrast, no corresponding countermeasures have been developed for these advanced technologies.

Police officers are somewhat familiar with telecom fraud, but more modern cybercrimes are relatively unfamiliar to them in this day and age.

In addition, there is a lack of modern surveillance equipment. Not to mention nationwide coverage, even in core cities like Tokyo, the surveillance coverage rate in public areas is pitifully low.

Just like the suicide website that Jiang Hang is currently investigating, it is essentially a product of the Japanese police's insensitivity to cybercrime and their allowing it to grow unchecked.

It is conceivable that in the future, cybercrime will inevitably become a focus for police forces around the world, requiring them to invest significant human resources in this area.

Since he had noticed the talent of the man from the mountain village, guiding him in that direction would not be a big problem.

After all, if big data and crime models can really be developed, it could really reduce the number of so-called famous detectives to ordinary cases like finding lost cats, dogs, or mistresses.

When the police leadership finally takes notice of cybercrime, a "professional elite" who is skilled in hacking and has foresight regarding cybercrime will likely immediately attract their attention.

Of course, although Jiang Hang felt he could train Shan Cuncao to become a cyber police officer, he did not give up teaching Shan Cuncao other criminal investigation techniques that could be used at crime scenes.

Before cybercrime attracts the attention of the police leadership, it's more important for Yamamura Misao to first shed his reputation as a rookie police inspector.

Right now, this case looks like a good opportunity.

By identifying the suspect's car from the tire tracks and scattered paint left at the scene, and then questioning vehicles and passersby who had passed through the area during that time based on the direction the suspect fled, useful information could be obtained from them.

A dark blue car with obvious dents and collision marks on the front would be quite noticeable on the road.

Then they gradually narrowed down the search area, slowly pinpointed the suspect's location, and finally arrested him.

As long as you follow the steps in the investigation, even someone with absolutely no deductive reasoning skills can easily solve a case using this method.

The only drawback is that this method is not as efficient at solving cases as the brains of detectives.

In reality, detectives often need to rely on evidence collected by frontline police officers at crime scenes to make their next deductions.

And isn't the biggest advantage of the police over famous detectives simply their numbers?

Unless it's a hellish place like Tokyo where a bunch of criminal cases happen every day, the number of police officers in other places is generally sufficient to meet the needs.

Yamamura Misao's current police rank is Assistant Inspector, but this is only because he is still in his probationary period. Therefore, he does not have any subordinates yet and usually has to learn from the older generation of police inspectors.

Once he solves a few more cases, he can be promoted ahead of schedule and become a full-fledged police inspector.

In Tokyo, a police inspector might only be able to serve as the head of a section under a division, like Inspector Megure, but in Gunma Prefecture, a police inspector has the opportunity to directly become a division chief or deputy division chief.

At that time, Yamamura Misao's men will naturally be assigned a team of police officers. How to arrange these officers to carry out their work at the crime scene is something Yamamura Misao needs to learn.

Therefore, this case, which is not too difficult but involves a considerable amount of money, is quite suitable for training the rookie policeman, Yamamura Takashi. Jiang Hang only needs to give the other party some hints at some key points.

Thinking about this, Jiang Hang couldn't help but sigh, realizing how dedicated he had been as a kung fu teacher.

How should Yamamura Misao introduce his mentor to others after he completes his apprenticeship?

It's said that he learned kung fu from a famous detective, and also mastered advanced hacking and criminal investigation techniques along the way?

Chapter 475: Chapter 471: The Road to Upgrading for Mountain Village Mischief

When Yamamura arrived at the scene with several police officers, the ambulance had already arrived and taken away the body of the victim, whose identity was still unknown.

Traffic police from Akina Mountain arrived at the scene to investigate the origin of the crashed car with the fake license plate.

Therefore, when Yamamura and his group arrived and saw the lively scene, they were momentarily at a loss as to which direction to begin their investigation.

The police officers under Yamamura Misao's command awaited instructions from their superior, while Yamamura Misao immediately rushed over to greet Jiang Hang.
