Yang Qingyuan waited until everyone left and took out a small bottle from his arms, which contained Dali Temple's secret recipe, Bloody Light Juice.
The policeman on the side immediately held a black cloth and quickly built a simple black shed on the ground with extremely skillful movements.
When the blood juice comes into contact with blood, it emits a slightly blue fluorescence, but this fluorescence can only be seen with the naked eye in a dark room.
Yang Qingyuan is a congenital person and has Dao pupils. He can see fluorescence even in the sun, but after all, it must be recorded as evidence in the case file and must be visible to everyone in order to be the basis for finalizing the case.
After the black cloth shed was built, Yang Qingyuan used his true energy to suck out a drop of juice and put it into the palm of his hand!
The output of Blood Light Juice is very low. It is also a high-end technical investigation item in Dali Temple. Ordinary police officers must apply to their superiors for use before they can use it after approval.
After the juice is refined, it needs to be diluted and used with a special spray device made by Dali Temple. This will not only spray it evenly, but also prevent the waste of bloody juice to the greatest extent.
However, with Yang Qingyuan's true energy control, the effect is much better than ordinary sprayers.
A drop of bloody juice is enough to cover a large area of ground under Yang Qingyuan's internal power.
As the bloody juice was pulled by Yang Qingyuan's internal force, it splashed everywhere and evenly sprinkled on the charred ground.
There was no reaction at all on the ground inside the dark shed.
The place Yang Qingyuan chose was the place where a charred corpse lay before. If the mountain people of Sanhe Village were really killed by swords, then there would definitely be traces of blood where they lay, and the blood and juice would be spilled.
Will show blue fluorescence.
But not only in the dark shed, but also outside the shed, Yang Qingyuan could not see the fluorescent reaction produced by the blood juice when it encountered blood.
Yang Qingyuan looked at the scorched black ground and immediately realized that it might not be that there was no blood, but that the flames made it impossible for Blood Light Juice to detect blood stains.
The original luminol reagent relies on hemoglobin in the blood. Hemoglobin contains iron, and iron can catalyze the decomposition of hydrogen peroxide, turning the hydrogen peroxide into water and single oxygen. The single oxygen then oxidizes luminol to make it glow.
, to detect blood stains.
Yang Qingyuan didn't know the principle of Xueguang Juice, but if hemoglobin was used to detect blood stains, it would most likely not be detected.
The mountain fire was raging that day, and the hemoglobin had already solidified and deteriorated under the high temperature, so of course there would be no reaction.
"Zhang Captou, do you want to change places?!"
Yang Qingyuan waved his hand, "No need!"
After speaking, Yang Qingyuan secretly sent a message to Song Hui's father, "Mr. Song, under the high temperature of the mountain fire, the blood juice has lost its effectiveness! What happens next depends on you!"
Professional matters should be left to professionals!
Song Hui's father then directed everyone to spread flax on the spot where the charred corpse originally lay.
Although the charred corpse had been moved down the mountain before, the Dali Temple police officers had received basic training in on-site handling and used wooden sticks to locate the original location of the corpse.
After a while, the places where the thirty-seven charred corpses lay were covered with flax.
"ignition!"
Following Song Hui's father's order, thirty-seven places of flax were set alight.
The flax burns and the fire rages.
The evil hidden under the scorched earth of Mikawa Village will also be revealed in this firelight.
When the flax was almost burned, a human-shaped grease mark was formed on the ground.
Everyone around was stunned.
Yang Qingyuan had also heard of this method, but he always thought it was just a legend and never thought it would actually work.
"Record it truthfully!"
Song Hui's father said to the policeman on the side.
Yang Qingyuan looked at the human-shaped grease on the ground and asked uncertainly, "Is this the legendary 'flax' method of painting corpses!?"
"Of course!!" Seeing Yang Qingyuan's shocked expression, Song Hui's father felt proud.
In his eyes, Yang Qingyuan, who was able to create the concepts of blood juice and texture-revealing powder, was a rare criminal investigation genius. His actions including wearing whale skin gloves at the scene, covering the shoes with thin wooden boards and other actions to protect the scene were all indicators of Yang Qingyuan's criminal investigation genius.
reflect.
Song Hui's father would naturally be proud of being able to shock such a person.
"But why is this?!"
This is unscientific!! Yang Qingyuan shouted in his heart!
Song Hui's father was naturally happy to help Yang Qingyuan clear up his doubts.
"When a person is burned by fire, the oil in his body will seep to the ground under high temperature. Now if he is roasted by fire again, the oil will overflow again."
No! This is very scientific!
"If the deceased is burned to death by fire while he is awake, he will inevitably struggle continuously until death, and the oil in his body will splash everywhere. If he is roasted with fire, the oil spilled from the ground will not form a human shape."
"Zhang Captou, please see, on the ground in Sanhe Village, the grease has condensed into human shapes, which means that the people were killed or stunned first and then burned. In this way, the grease will not splash around and overflow.
The grease will form a human shape. This is Hu Ma's method of 'painting a corpse'."
Yang Qingyuan nodded in praise, this is so scientific!!
The thirty-seven humanoid marks that appeared in the fire are the most powerful evidence of the truth of the mountain fire.
The so-called lightning strikes causing wildfires were just done by the real culprits behind the scenes to cover up their crimes. Their purpose was to burn all traces and evidence, making people think that these people died in the wildfires.
"What a vicious thought!"
Yang Qingyuan felt that he had simplified the case. Starting from the toadstool, nearly a hundred people had died, but he still hadn't found what was hidden behind it!
After recording, everyone in Dali Temple conducted a thorough search of the ruins of Sanhe Village.
But there was still nothing new gained, just when Yang Qingyuan was about to leave.
Suddenly I felt a sense of peeping coming from behind. This feeling was so familiar!
Just like in Li Bailiang's mansion three years ago.
"who!?"
Yang Qingyuan waved a sword energy with his backhand.
Today, Yang Qingyuan has mastered the first-level living sword of the "Innate Body-Breaking Invisible Sword Qi" to perfection. The sword Qi is sharp and fierce and indestructible!
The sword energy passed by, and four large trees that were hugged by three people were chopped off by Yang Qingyuan's sword.
As the big tree collapsed, a white shadow rose into the sky! Along with countless white feathers falling down.
The white figure's lightness skills have reached a level that is difficult for ordinary people to understand. He actually picked up the feathers, accelerated several times, and rushed towards the distant mountains and forests.
"A good host will not let his guests go easily!"
Before the words could fully reach the ears of the surrounding police officers, Yang Qingyuan's figure had already disappeared.
Wherever a black figure went, white feathers scattered in all directions.
In terms of senses, it seems to be faster than the previous white figure.
At this moment, Liu Wangshu and Li Mochou are not here! Although the remaining people are not considered Zhan Wu Zha, they can no longer intervene in the battle at this level. They can only watch the two figures flying into the distance.
