Comprehensive Wu Jianghu: I am Dali Temple Minister

"This this……"

Di Zhiyuan looked at the blue light all over the floor, feeling like a stormy sea in his heart.

"Old Di, what do you look like?"

Hearing Yang Qingyuan's question, Di Zhiyuan, who was in a state of shock, also calmed down. Looking at the blue light all over the floor, he had a flash of inspiration.

"This is like!! Blood!!"

"That's right, this is the trace of blood splatter here!! There used to be a lot of blood here!" Di Zhiyuan murmured to himself.

This product is made from a strange fruit accidentally discovered by the medicine king Sun Shichang. This fruit tastes bitter, slightly poisonous, and is difficult to use as medicine.

However, Yang Qingyuan discovered its unique feature when learning to refine medicine. When the juice meets blood, it will emit blue fluorescence, but the light is weak and can only be seen in the dark.

Isn't this the martial arts version of Miruno's reagent?Immediately, three fruit trees were planted on Wudang Mountain.

This juice was also named Xueguangguo by Yang Qingyuan.

In other words, when the juice meets blood, it will glow blue.Once this fruit is used, there will be blood (disaster).

Di Zhiyuan walked slowly to the side of the fluorescent light, squatted down and observed carefully.

"The fluorescence has such a large area, which means that there is a lot of blood splashed out, but from this point of view, such a large amount of bleeding may not be able to cause death."

"But, whose blood is this?" Yang Qingyuan nodded in agreement, and then he had a headache again. Although he made the martial arts version of the magic-modified Miruno reagent, he couldn't extract and identify the DNA!

This kind of high-end biotechnology cannot be changed by martial arts magic.

Di Zhiyuan walked around the blue fluorescent ground, measuring the void with his hands as he walked.

"It's so strange!"

"My lord, although I don't know whose blood this is, I can speculate that it's not Li Bailiang's blood!"

Yang Qingyuan was taken aback, and asked, "It's not Li Bailiang's, how do you say that?"

Di Zhiyuan pointed to the ground and said, "From the shape of the blue light here, the blood is splashed, so there must be wounds on the bleeding person. But during the day, the adults also checked Li Bailiang's body, and the body was covered with blood. There wasn't a wound up or down. There was no way that much blood was spilled."

Yang Qingyuan nodded, and Di Zhiyuan's analysis made sense. Although he didn't know how to identify traces, he could tell from the bloodstains on the ground that the blood was splashed out, which was inconsistent with Li Bailiang's death.

"What's more, what should be done to form such a blood splash." Di Zhiyuan pointed to the ground and said, "Look, my lord, the blood here is almost splashing in all directions. Usually, murderers use sharp weapons to kill people, nothing more than cutting and stabbing." If it is cut, the blood will splash along the direction of the weapon, and the blood should be long and narrow. If it is stabbed, the blood will be sprayed towards the murderer as an umbrella, even if the murderer lays the dead down and stabs from top to bottom It should be splashing upwards. It will never look like this!"

Di Zhiyuan lived up to his reputation as a detective, and immediately discovered the strangeness of the pool of blood.

"Zhiyuan's words are reasonable, so there must be something wrong with this matter." Yang Qingyuan realized that sometimes he was only worthy of calling 666 in front of Di Zhiyuan.

Although his martial arts and literary talents are much better than Di Zhiyuan's, and his appearance and demeanor are far better than him, but when it comes to detective reasoning, there is still a certain gap between the two sides.

"By the way, my lord, I will inquire about the matter of the next official!"

Yang Qingyuan waved his hand, "It's not Yingmao (work) time, so don't call me "Brother Zhiyuan". In this way, you and I are about the same age, and you are slightly older than me, so I will call you Brother Zhiyuan."

Di Zhiyuan didn't like these etiquettes originally, so he couldn't agree more with Yang Qingyuan's proposal, "Okay! Brother Qingyuan!"

Yang Qingyuan: "..."

He never expected that Di Zhiyuan would be so easy-going, and he would immediately change from an adult to Qing Yuan's brother, at least he should call him Brother Qing Yuan or Brother Yang!

"What did you ask just now!?"

"Ah! I want to ask, can this thing detect when the blood was made?"

"...!" Suddenly, the room fell silent.

"Brother Qingyuan, what's wrong!!?"

Yang Qingyuan scratched his head and said: "This is not possible, but the blood stains within three months can emit blue light when sprayed with this kind of blood light juice."

Yang Qingyuan's answer made Di Zhiyuan think for a while, "What do you mean, this bloodstain may be from three months ago?"

Yang Qingyuan nodded in embarrassment. He had been a civil servant of the Imperial Academy before, the real kind of civil servant, who spent his whole day writing books and giving lectures. How could he come to test this kind of trace experiment?

Di Zhiyuan thought for a while, yes, this kind of blood light juice can measure the washed blood, which is already a rare wonder in the world. How could it be possible to measure the time of death by dripping blood?

"Although we don't know who the blood is, 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 got up and walked to Li Bailiang's bed, then took out a pair of whale leather gloves from his arms and put them on, then took out another jade bottle, poured out a touch of powder from the bottle, Yang Qingyuan put the powder gently In the palm of your hand, use your true energy to flick.

In an instant, the powder floated to the bedside.

In Di Zhiyuan's eyes, the miracle reappeared.

Light again!

But this time it's a green silver light.

Unlike the large blue light on the ground, the green light is very small, but it is distributed near the bed.

Di Zhiyuan saw that these green lights were no more than the size of a thumb, and when he got closer to take a closer look, he couldn't help but gasp.

Brother Qingyuan's methods are so terrifying.

The green fluorescent lights beside the bed are clearly human fingerprints.

"Brother Qingyuan, what is this?!"

Yang Qingyuan handed the bottle to Di Zhiyuan.

"This is the wrinkle-revealing powder. Human fingers are always stained with sweat and grease. When this powder comes into contact with it, it will emit green fluorescence!"

Of course, this is also the medicinal powder developed by Sun Shichang, Yang Qingyuan's begging medicine king, but mass production has not yet been achieved.

Thinking of this, Yang Qingyuan couldn't help but sigh, the king of medicine is a great talent in biochemistry!With this talent, if he was born in another world, punching Mendeleev and kicking Leeuwenhoek would definitely not be a dream.

"This grain revealing powder can make fingerprints appear within three days without a doubt."

Di Zhiyuan looked at Yang Qingyuan... the two bottles in his hands, his eyes were shining, whether it is blood light juice or grain revealing powder, they are all artifacts of criminal investigation, if they can be promoted to the world, the detection efficiency of criminal cases will be greatly improved !

Di Zhiyuan didn't have much interest in martial arts, and it was enough to protect himself; he didn't have much pursuit of official career, just enough to stand up.But he is extremely fanatical about the way of criminal investigation and judgment.

"Brother Yang's talent is as good as heaven and earth! Di Mou only knows today what it means to be someone beyond human beings and someone beyond the sky! Convinced! Convinced!"
