Don't think that modern criminal investigation methods are particularly superb, just think that the previous detection methods are particularly old-fashioned.

The development of modern criminal investigation is mainly reflected in technology, such as DNA and fingerprints.

But fundamentally speaking, criminal investigation mainly relies on the brains of the person handling the case.

This will not change in the past, in the present, or in the future.

An Yizhi can think of going to the gem store and asking where the gems left behind by the murderer came from. The police, the guard in this dungeon world, are naturally very clear. Moreover, they have official status, and there are many of them, so they can search faster and faster than An Yizhi.

But this clue is not easy to catch, otherwise the murderer would have been arrested now.

There are many shops selling gems in the imperial capital, and Clark once said that the gem business in the imperial capital has been monopolized by his gem psychedelia, which is the business of magic gems.

It's not bad, anyway, the gems left by the murderer are all magic gems, and Clark made it clear that there won't be a single magic gem material flowing out of his store.

But he is talking about high-end materials, and low-end materials are not among them, such as the fire agate mentioned in the dossier is a fairly low-end of the magic gem.

This gem may be made into a ring or necklace by ordinary jewelry stores, or it may be bought by adventurers as a consumable or enchanted by their own equipment, because the consumption is relatively large, so this gem is also considered a type of magic consumable.

There are a lot of shops in the city that operate these low-end gem businesses, and it is very difficult to investigate, and due to the Midsummer Festival, a large number of tourists have poured into the imperial capital, among which the adventurers who have nothing to do and can give themselves a holiday account for the majority of tourists, and it is normal to take the opportunity to buy some gems or something in the imperial capital.

Also because of the midsummer season, the security team was already understaffed in order to cope with the surging flow of people, and then they went to check the huge number of shops and the floating population who had purchased these gems......

The guards said: Give me a way to live.

In addition, magic gems are not contraband, they can only be regarded as controlled products, and a large number of transportation or transactions need to be reported and presented to prove that ordinary people carry a few pieces in small quantities will not attract attention at all, even if they bring a box of gems to walk around the streets and alleys, it is a big deal to say that they are coming to the imperial capital to expand the gem business.

Therefore, this line does not have the ability to follow the vine at all, it will take a lot of manpower and time to get it done, and there must be someone in the guard team doing it, just when will the result be ......

Don't expect anything from here.

The only good news at the moment is that Clark said that high-grade magic gem materials will not flow out of his shop, and this serial murderer is a bit obsessive-compulsive, and every time he kills, he always leaves gems at the scene that match the identity and status of the victim, so that unless the murderer gets particularly high-end magic gem materials, the guy with a very high status in the imperial capital should not have to worry about being targeted.

There is no need to doubt whether a serial murderer with the purpose of killing is so paranoid, it can be said that this murderer has been broken in his heart as an ordinary person since he started the indiscriminate killing operation, and this paranoia can be found in many serial murderers.

But it's not 100% safe, as Clark also mentions the presence of black marketeers in the Imperial Capital, and the killer may be able to get gems from them.

Unlike the first time I went to the magic city, at that time, An Yizhi could be said to be ordered to investigate the case, Farq not only gave a large amount of activity funds, but also accompanied Fast to transfer the magic crusaders, and the convenience of intelligence and other conveniences was also a big open door, and he could do whatever he wanted, and all the merchants in the black market would be under no pressure.

And this time, there is no foreign aid except for An Yizhi and Kara, Kara said that the city defense army can be transferred, but with the current situation, how many people are left in the barracks of the city defense army......

Thinking about what to do next, Kara was like Hela, changing her previous image of a cold-faced beauty and chattering excitedly in Ann's ear.

It was just to see that this girl was easily overexcited, so An Yizhi didn't go to the carriage, after all, there was a listening spell on it.

As he walked, Ann suddenly saw a large crowd of people walking down the road, it was a procession celebrating Midsummer.

The three oversized flatbed trucks, which seem to be powered by magic, are not fast, and they are not as good as they are.

This is the stage for the show.

On the flatbed, bards and bands play cheerful tunes, graceful dancers dance in ornate costumes, and even domesticated beasts and trainers perform in the same cage.

At the end of the convoy, a guy dressed as a clown threw candy at the crowd while shouting:

"Long live Your Majesty the Emperor! Long live Midsummer! ”

The crowd shouted along, and it sounded really happy.

An Yizhi stood in place and watched the parade slowly pass by, to say curious, it was a little, after all, I had never seen this kind of parade float in reality.

Seeing that Ann was a little interested, Carla said:

"These performers are recruited from all over the country, divided into teams, and they will perform all day in the city."

"No breaks?"

"Of course, you have to take a break, and when the parade reaches a place where there are fewer people, you will stop and change the shift, and there are several groups of performers waiting to go up and perform, which is a good opportunity to make a name for yourself."

It's a good choice to follow the team to watch the show if you're free, and An Yizhi can somewhat understand the audience who go to the scene to watch the performance, this kind of atmosphere is impossible to experience by watching TV at home anyway.

Unfortunately, though, he apparently doesn't have that kind of spare.

"By the way, I remember you weren't a student at the military academy? Midsummer holiday? ”

Quan should be chatting, An Yizhi asked casually.

"I dropped out."

Carla Says:

"The last year is mainly based on confrontation training and exams, the school will not teach more knowledge, and when you graduate at the age of 17, you will return to China to join the army, and the average aristocratic international student will choose to drop out in the final year and return to China directly to use her family connections to enter the army."

"Then why did you stay in the imperial capital honestly?"

This sentence seemed to poke Kara's sore spot, and her face sank and she said:

"Because of the interference of the eldest brother and eldest sister, if I want to join the army, I can only start from the most basic officer, not from the staff department as a staff officer, my father has been busy with the war at the border recently, and he has no time to take care of my affairs, so he can only stay in the imperial capital temporarily."

Sure enough, every family has a scripture that is difficult to read, and in the eyes of these nobles, whether it is a brother or sister or a biological parent, as long as they are their own way, they are undying enemies.

Kara's eldest brother and sister plan to use the excuse that the border war is too tight to put Kara into play, and Kara, who can't join the army and can only hang out at home, can't do anything, and in the end she can only obediently go out and get married.

Her father, the Duke of Westford, could also see the contest between the children, but did not stop it, he was a pragmatist after all, and since he lost the battle for inheritance, it was natural that he would not arouse any sympathy from him.

"You said you have a little brother? Isn't it good for you to join forces? ”

"My brother ......"

Kara hesitated, as if considering her words.

"He's only 8 years old now."

"Too young?"

"No, it's too dangerous."

What's so dangerous about an eight or nine-year-old child?

"He's not like a kid, and even though we don't have a lot of contact, it's nice to be around him."

An Yizhi shrugged his shoulders, saying that your nobleman's family is really messy, and he didn't plan to delve into it, anyway, he just chatted and asked casually.

"Let's get down to business, apart from the information on those cases, do you have any other clues in your hands?"

It may be the first time that An Yizhi has asked such a reliable question, and Kara obviously hasn't turned this circle.

"That's all I know...... Wait a minute. ”

As she spoke, the white light of communication skills lit up in her ears, and she turned her head to mutter, then turned around and said:

"There are new clues, the guards have found a new victim."

Sure enough, the undead don't give clues.

–‐‐——–‐‐——

Kara's carriage followed the two of them at all times, and when she got the news, she rode it to the scene of the crime.

It was a three-story residential building that looked like a large apartment with a lot of residents.

The crime took place near the staircase, on the first floor, in a house.

An Yi pointed out that the scene had been cordoned off by the security team when they arrived, but in order not to cause panic in public opinion, they only cordoned off the room at the scene of the crime, and did not corclose the entire residential building.

As soon as she arrived, Kara rushed out of the carriage and found the person in charge standing at the top of the stairs to inquire about the situation.

"There were two deceased, a couple, the man was a teacher, the woman was a housewife, and the first discoverer was there."

Kara followed the fingers of the head of the guard, but saw only two eleven or twelve-year-old boys.

"They were students who came to the teacher's house for tutoring, and according to them, they arrived here at the appointed time, knocked on the door for a long time and no one answered, climbed up the window and saw the victim through the curtains, so they asked the guards patrolling nearby for help."

Kara nodded, said hello, and went to ask the two children for details.

And An Yizhi didn't have the consciousness of a bodyguard at all, and directly crossed the blockade line of the guards, and Shi Shiran entered the scene of the crime.

Anyway, there are blue vests (the uniforms of the guards) all around, and there is no need to worry much about Kara's danger, so instead of listening to their nonsense, Ann pointed to himself and saw for himself.

And the guards also saw that An Yizhi came with Kara, who was the daughter of the four dukes' families, and he was a fox and a fake tiger, and no one dared to stop An Yizhi when he entered the scene of the crime.

A yellow cloth cordon was pulled up at the door, and An Yizhi raised his foot and stepped over, seeing that there were very new marks of impact on the wooden door, and the lock was locked, which was probably caused by the guards when they broke the door.

In other words, could the prisoner not have entered through the main entrance, or had he used the key to lock the outside after he left?

Walking on, passing through a narrow hallway, An Yizhi immediately asked a strong smell of blood......
