Chapter 23: Visiting the Li Mansion at Night (Part 2)
"This this……"
Di Zhiyuan looked at the blue light all over the ground, feeling like a turbulent wave in his heart.
"Lao Di, what do you look like?"
After hearing Yang Qingyuan's question, Di Zhiyuan, who was originally in a state of shock, calmed down and looked at the blue light all over the ground, and a flash of inspiration flashed.
"This is like!! blood stains!!"
"That's right, this is the trace of blood spattering here! A lot of blood once flowed here!" Di Zhiyuan couldn't help but mutter to himself.
This product is made from a strange fruit accidentally discovered by Sun Shichang, the king of medicine. This fruit tastes bitter, is slightly poisonous, and is difficult to use as medicine.
However, Yang Qingyuan discovered its unique feature when he was learning to make medicine. When this juice meets blood, it will emit blue fluorescence, but the light is weak and can only be seen in the dark night.
Isn't this the martial arts version of Miruno's reagent? Three fruit trees were immediately planted on Wudang Mountain.
This kind of juice was also named Xueguangguo by Yang Qingyuan.
Literally, when the fruit juice comes into contact with blood, it will glow blue. Once this fruit is used, there will be a disaster of blood.
Di Zhiyuan slowly walked to the fluorescent light, squatted down and observed carefully.
"The fluorescence has such a large area, which means a lot of blood was spilled. But judging from this place, such a huge amount of bleeding is enough to cause death."
"But whose blood does this belong to?" Yang Qingyuan nodded in agreement, and then got a headache again. Although he made the martial arts version of the magically modified Miruno reagent, he could not extract and identify DNA!
This kind of high-end biotechnology cannot be modified by martial arts magic.
Di Zhiyuan walked around the blue fluorescent ground, measuring with his hands as he walked.
"How strange!"
"Sir, although I don't know whose blood this blood belongs to, I can surmise that it is not Li Bailiang's blood!"
Yang Qingyuan was stunned and asked, "It's not Li Bailiang's, how can you say this?"
Di Zhiyuan pointed to the ground and said, "From the shape of the blue light here, it can be seen that the blood is splashed, so there must be wounds on the bleeding body. But during the day, your Excellency also checked Li Bailiang's body. The body was covered with blood.
There is not a single wound up and down. It is impossible for so much blood to be spilled."
Yang Qingyuan nodded. Di Zhiyuan's analysis made sense. Although he didn't understand trace identification, he could tell from the blood stains on the ground that the blood was splashing out, which was inconsistent with Li Bailiang's death.
"Furthermore, how can we create such a blood splatter?" Di Zhiyuan pointed to the ground and said, "Look, sir, the blood here is almost splattering in all directions. Generally, murderers use sharp weapons to kill people, nothing more than cutting and stabbing.
If it is slashed, the blood will inevitably splash along the direction of wielding the murder weapon, and the shape of the blood should be long and narrow. If it is stabbed, the blood will be like an umbrella and spray towards the murderer. Even if the murderer lays the deceased flat and then stabs from top to bottom, the blood will
It should be splashing upward. It will never look like this!"
Di Zhiyuan lived up to his reputation as a detective, and he immediately discovered the strangeness of this blood stain.
"Zhiyuan's words are reasonable, but there must be something fishy about this matter." Yang Qingyuan found that in front of Di Zhiyuan, sometimes he only deserved to call Liu Liuliu.
Although Yang Qingyuan knew that his martial arts and literary talents were much better than Di Zhiyuan's, and his appearance and demeanor were far superior to him, there was still a certain gap between the two when it came to detective reasoning.
"By the way, sir, please ask me about this matter!"
Yang Qingyuan waved his hand, "It's not Ying Mao (work) time now, so don't call me Sir. In this way, you and I are similar in age, and you are slightly older than me, then I will call you Brother Zhiyuan."
Di Zhiyuan's temperament didn't like these etiquettes, so he couldn't agree more with Yang Qingyuan's proposal, "Okay! Brother Qingyuan!"
Yang Qingyuan: "..."
He didn't expect that Di Zhiyuan would be so easy-going, and he would immediately transform from an adult to Brother Qingyuan, so he could call him Brother Qingyuan or Brother Yang!
"What did you want to ask just now!?"
"Um! I just want to ask, can this thing detect when the blood stains are from?"
"...!" Suddenly, the room became quiet.
"Brother Qingyuan, what's wrong!!?"
Yang Qingyuan scratched his head and said: "Time cannot be detected. Blood stains within three months can emit blue light when sprayed with this blood juice."
Yang Qingyuan's answer made Di Zhiyuan think for a moment, "You mean, this blood stain could be from three months ago?"
Yang Qingyuan nodded awkwardly. He had been a civil servant of the Hanlin Academy before. A real civil servant who spent all day revising books and giving lectures. How could he come to test this kind of trace test?
Di Zhiyuan thought about it for a while. Yes, this kind of blood-light juice can measure cleansed blood, which is a rare thing in the world. How can it have such an incredible function of measuring the time of death by dripping blood?
"Although we don't know whose blood this blood belongs to, we can conclude that within three months, a murder must have occurred in this room!"
"And Li Bailiang's death may be related to this murder case!"
Yang Qingyuan stood up and walked to Li Bailiang's bedside. Then he took out a pair of whale skin gloves from his arms and put them on. Then he took out another jade bottle and poured out a powder from the bottle. Yang Qingyuan gently placed the powder on it.
Put it in the palm of your hand and stir it with your true essence.
In an instant, the powder floated to the bedside.
In Di Zhiyuan's eyes, a miracle reappeared.
It’s light again!
But this time it's green silver light.
Unlike the large blue light on the ground, the green light is very small, but distributed near the bed.
Di Zhiyuan looked at it and saw that these green lights were no more than the size of his thumb. When he got closer and took a closer look, he couldn't help but take a breath of air.
Brother Qingyuan's methods are so terrifying.
The green fluorescence beside the bed was clearly a person's fingerprint.
"Brother Qingyuan, what is this?!"
Yang Qingyuan handed the bottle to Di Zhiyuan.
"This is a wrinkle-marking powder. People's fingers are always stained with sweat and grease. When this powder comes into contact, they will emit green fluorescence!"
Of course, this is also the medicinal powder that Yang Qingyuan begged Sun Shichang, the king of medicine, to develop, but it has not been mass-produced yet.
Thinking of this, Yang Qingyuan had to sigh, the King of Medicine is a great talent in biochemistry! With this talent, if he were born in another world, punching Mendeleev and kicking Leeuwenhoek would definitely not be a dream.
"This fingerprint-revealing powder can make fingerprints appear clearly within three days."
Di Zhiyuan looked at Yang Qingyuan...the two bottles in his hands, his eyes glowing. Whether it was blood juice or wrinkle-marking powder, they were all artifacts of criminal investigation. If they could be promoted to the world, they would greatly improve the efficiency of criminal case detection.
!
Di Zhiyuan didn't have much interest in martial arts, as long as he could protect himself; he didn't have much pursuit of official career, just enough to establish himself. But he was extremely passionate about criminal investigation and case-solving.
"Brother Yang is so talented that he knows everything about heaven and earth! Only today did Mr. Di know what it is that there are people outside the world, and there is heaven outside the world! I am convinced by my heart! I am convinced by my heart!"
