There were many bureaucracies in the Great Zhou Empire, and each bureau had its own archive storage warehouse. However, in terms of professionalism, it could not be compared with the special archives set up by the imperial court.
The so-called case record library is similar to the big data of later generations. It can be combined based on various details to provide important clues to investigators and investigators.
It is worth mentioning that neither the Jingzhao Prefecture, the Ministry of Punishment nor the Dali Temple can directly access the files in the archives.
Only bad people’s yamen have this power!
Zhao Xun couldn't help but feel a sense of pride in his heart.
It seems that joining the bad guys is not entirely a bad thing.
but…
"Brother Jia, Yushi He met Hu Shang in a wine shop on August 13th but did not return. He died suddenly at home on August 15th. This time is too tight. Moreover, the murderer was too late to choose the Mid-Autumn Festival.
Isn’t it cruel?”
Zhao Xun analyzed it from the perspective of an ordinary person, but Jia Xingwen obviously didn't care about this.
He smiled contemptuously and said lightly: "The murderer is vicious? What's wrong with this? You will have many opportunities to meet all kinds of vicious people in the future. Besides..."
Jia Xingwen said with a cold expression: "Maybe the person who killed He Yushi was not a human being."
Zhao Xun shuddered and subconsciously took a step back.
"No...not a human being, what is that?"
"It may be a demon. I smelled the aura of demon in Yushi He's mansion, and I used a soft brush to pick up some scale powder left by the monster."
Jia Xingwen took out a bag filled with scale powder, then took out a piece and sent it to Zhao Lun.
Zhao Xun smelled it and then frowned instinctively.
"Why does this smell so strong?"
The smell is very strange, a mixture of irritation and stink.
"Yes, this is the smell of monsters."
Jia Xingwen nodded slightly and said with some relief: "It seems that cleansing the marrow is still useful. If you had the qualifications before, you would definitely not be able to smell the evil spirit."
Zhao Xun had mixed feelings in his heart.
In the past, he would never have believed that there were monsters in this world.
But since such things as time travel have happened, it is not surprising that there are monsters and demons in a parallel and imaginary world with practitioners.
"If it was done by monsters, what was their purpose?"
Although Zhao Xun read a lot of detective novels in his previous life, detective novels are based on the conventional world.
If it was done by a monster, can it also be applied?
Zhao Xun thought for a moment and decided to give it a try.
"Brother Jia, you can't make inferences without any evidence. In that case, you can only go astray."
This is what Holmes said, but it is very suitable for Zhao Xun to apply it.
Jia Xingwen was slightly startled and muttered silently.
"What you say makes sense, but what exactly do you want to say?"
"I just think it's a bit too arbitrary to judge that He Yushi was killed by a monster just based on the monster's aura and scale powder."
Zhao Xun composed himself and continued in a harmonious voice: "According to the records, He Yushi was killed around Zishi. This was inferred based on the time when the body spots appeared after Wu Zuo's autopsy. But according to He Yushi's servant,
They didn't hear any strange noises around midnight. If they were practitioners, they could use flying swords or light skills to explain it. But if they were monsters, how could they kill people and walk away without making any noise?
Woolen cloth?"
"You mean, maybe someone deliberately faked the scent of a monster and then spread the monster's scale powder in the house?"
Jia Xingwen captured Zhao Lun's point of view very keenly.
"This possibility does exist. There is a way to try it out."
Zhao Xun actually didn't want to show off in such a hurry, but unfortunately he was now guilty.
Although His Majesty the Emperor did not say it clearly, the meaning was actually very clear. Zhao Xun must make achievements among bad people before he could completely atone for his crimes.
Otherwise, although he temporarily saved his life, the emperor's butcher's knife may fall at any time.
It is unrealistic to reason with the emperor in a feudal dynasty.
Zhao Xun can only adapt to this era as much as possible in order to survive better.
"What method?"
Jia Xingwen squinted his eyes slightly and stared at Zhao Xun with some amusement.
"I don't know if Brother Jia has heard of this sentence. Any perpetrator will leave evidence when he commits a crime, more or less, it is impossible to have no evidence at all. If the crime is committed by humans and covered up by monsters, maybe
We can identify them by taking fingerprints."
"fingerprint?"
Jia Xingwen had obviously never heard of fingerprints and looked at Zhao Xun in confusion.
"Well, Brother Jia can understand the so-called fingerprint as a handprint."
Of course, the Zhou Dynasty had no concept of fingerprints, but they definitely knew what fingerprints were.
Going to the Dali Temple of the Ministry of Punishment and going down to the Fuzhou County Yamen, basically all prisoners will choose to press fingerprints to plead guilty.
Sure enough, when Zhao Xun said this, Jia Xingwen immediately understood.
"It turns out to be a fingerprint. But this fingerprint... uh, how do you get this fingerprint? Even if someone really did it deliberately, but they have already escaped, we can't catch it even if we want to."
In Jia Xingwen’s understanding, fingerprinting requires the presence of someone.
"This is simple. We can use the powder visualization method to get fingerprints."
Zhao Xun explained carefully: "Human fingerprints will remain on objects that have been touched, especially objects with smooth surfaces."
Of course there is no glass in this world, but there are a lot of porcelain, lacquerware and wooden furniture.
It is easy to leave fingerprints on these objects. The key to the problem is how to extract them.
"We can use graphite powder and sprinkle it evenly on porcelain and lacquerware, so that explicit fingerprints can appear."
"But how to prove that this is not left by the dead He Yushi?"
"It's simple. Isn't He Yushi's body in the bad people's office now? Let's get it and press our fingerprints to compare."
"According to the records of the official script, He Yushi did not have a second marriage after being widowed. Although his main house was cleaned by servants, the servants would not touch the porcelain or lacquerware. Because He Yushi had a mysophobia. Of course, if Brother Jia is worried,
, you can also order all the servants in the He Mansion to take fingerprints and compare them with Yushi He's fingerprints."
Jia Xingwen nodded: "This is the safest."
Of course Zhao Xun knows that there is no fingerprint database in this world.
But he did not extract fingerprints on porcelain and lacquerware to obtain results directly from the fingerprint database.
All he had to do was to determine whether the murder was the work of a monster or an illusion deliberately created by someone.
