Bu Xihuan suddenly got up and walked into the house.

Twilight didn't stop him, he needed to see it with his own eyes.

The literati also hurriedly came to the porch, but did not enter the house, and waited outside the door with Wei Zhuozhi.

Bu Xihuan came to Twilight's side and lowered her eyes to look at her, Twilight knocked on the table and motioned for him to look, "The blood stains are blocked here." ”

I saw a fine blood stain next to the pen and ink on the desk, which should have been sprayed when the deceased's neck was cut, but this blood stain looked a little strange, and there was a piece of empty in the middle.

"There was originally something here, blood sprayed on the table, and the murderer took this thing to leave a blank of blood underneath. The shape of the blank ......," Twilight said, drawing a rectangle on it, "it should be a piece of paper. ”

Paper.

There are many things that can be written on paper, maybe it's official documents, maybe it's letters, maybe it's something else. If the content on this piece of paper is useless, it is impossible for the murderer to take it, and something very important must have been written!

The literati once said that the official document was not lost, that is, what was written on the table was not an official document, so the deceased was writing a letter at that time? If so, in addition to the contents of the letter, there is an equally important question - to whom is the letter addressed?

Twilight glanced at Bu Xihuan, and the man looked down at the empty space on the table, the candle shadow flickered, and half of the purple jade gilt mask was cold.

Obviously, this important letter, the contents of which he did not know, indicate that the letter was written behind his back.

Carry him on his back...... This is food for thought.

There is something worth pondering about this case tonight, the time when the man died was too coincidental, and it happened that when the man went to assassinate the attic in the backyard of the Shi Mansion, it seemed that the murderer knew that he was not there and took the opportunity to do it.

Twilight lowered her eyes, if she speculated like this, the Thorn Mansion would say that there were three forces in existence! And there is a high probability that the murderer is the person who assassinated the Shifu!

If the murderer is really in the assassin's mansion, Twilight will have doubts again, and she can't figure out the murderer's motive for killing. The identity of the man beside her was mysterious, and the murderer knew even his whereabouts, so it was impossible not to know when someone was running an errand in the public house. He picked someone to go on an errand, and he definitely didn't go to steal official documents and be discovered by the deceased to kill people, so he saw what was written on the deceased's desk, and he had a temporary idea? It doesn't make sense. If he thinks it's important, stealing it afterwards is much less risky than robbing it in person! Murder is the riskiest, so why should he choose the riskiest method?

Twilight had doubts in her heart, and knew that these were her speculations, and without evidence, even speculation could not be conclusive. But handling the case is a process of bold speculation and careful verification, and now that she has speculated, it is only necessary to seek verification.

"The murderer killed someone and took something, and he must have left quickly. He walked past his desk with a knife in his hand. Twilight looked at a bead of blood on the ground, one end of which was star-shaped, pointing to a low couch in the room. Twilight looked at the couch and fixed her gaze on the window behind it.

The window was closed, and the shadows of the trees were reflected in the window, swaying like ghost claws, as if a great secret had been shut out of the window.

Twilight walked over and pushed open the window.

The night breeze poured in from the window, Bu Xihuan walked to her side, the wind swept the robe, scattered the blood in the room, and brought a little freshness and elegance. The men of the Daxingshi tribe like incense, but he does not smell the rich fragrance on his clothes, but only smells the fresh air, which reminds people of the intoxicating fragrance of grass and leaves in the forest after the rain, which is quite refreshing.

Twilight's mind cleared up a little more unconsciously, and she looked out the window with Bu Xihuan.

There is a stone path outside the window, and a small pond behind it. The moonlight shone on the pond, and the sparkling waves reflected the faces of the two people behind the window, alternating clouds and sunny days.

The eyes of the two fell on the stone path, and there was no blood on the stone path, and it was impossible to see where the murderer had left.

The clue seems to be broken......

"There's a clue!" Twilight suddenly spoke, turning and walking outside the house.

Everyone followed her to the path behind the window, and in the distance, Twilight gestured for everyone to stop and not approach, and went up the path alone, crouching down near the window. I don't know what she was looking at this time, but I saw the bright moon at the end of the road, the young man in the middle of the road, and the night was lonely.

After a while, Twilight snorted at the gap between the two pebbles on the stone path, turned her head to look at the people in the distance, and pointed to her own findings, "The murderer's knife is stained with blood, and he came out of the back window, and there is no reason why there is not a drop of blood on the road." It is not said that he wiped it, and there are blood stains in the cracks in the stones. ”

Everyone had a cloudy and sunny face, and the literati said from afar: "Is it difficult to look at all the cracks in the stone and find out the blood stains to deduce which way the murderer walked from?" ”

The literati hadn't opened his mouth since the autopsy, and when he opened his mouth, Twilight suddenly turned cold, "It's up to you to see it, I don't want to see it!" Eye pain! ”

The man choked, and his face turned a little red. He also knew that this method was not very useful, even if he could see which way the murderer had left. Then since you know how to wipe the bloodstains, you won't be stupid enough to leave bloodstains all the way to the foothold. In the end, it is necessary to find some more bloodstains, at most it can only provide the direction of the murderer's departure, and there is still no clue who the murderer is.

"What did he wipe the blood with?" Twilight spoke suddenly.

The literati was stunned for a moment, and Twilight snorted, "There was blood splattered at the scene, it was impossible for him to avoid it clean when he killed someone, there must have been blood on his body!" He knows how to wipe the blood on the ground, would he be stupid enough to wear a bloody suit and carry a bloody knife to swagger through the Assassin's Mansion? ”

Bu Xihuan looked at the pool next to the stone path, the night breeze on the pool surface rippled, and the man's eyes were also a little dark, and Twilight nodded when he saw it.

"That's right! He will not wear the bloody clothes everywhere, he will definitely throw them nearby, that pool is a good place to throw clothes, and it should be the bloody clothes on his body that wipes the blood stains on the ground. Twilight got up as she spoke, walked to the stone path, glanced at the grass by the pool, and waved to everyone.

Everyone hurried over, and followed Twilight's hope, only to see a few signs of trampling on the grass, and not far from the pool, on an exposed muddy ground, there was a mud footprint falling quietly in the moonlight. It had rained two days ago, and the footprints were quite clear, and along the footprints, you could see that the grass had been trampled in several places, and when he re-walked the stone path, the murderer deliberately rubbed the mud on the soles of his shoes on the grass. Still, he landed some mud on the stone path as he walked up the path.

Where the murderer left is already clear.

Twilight looked at the mud from afar, her eyes were a little dark and uncertain, and she turned to the little girl and said, "You go down there and see where you can follow." ”

The little girl was stunned when she heard this, from the beginning of the autopsy, she was doing these things, she was afraid that they would destroy the traces of the scene, why was she willing to believe him this time and let him take a look?

"You think the killer will really let you follow his footprints to find him? He is a person who can wipe even a few drops of blood, how can these scattered mud marks not be a trick? He'd already wiped the soles of his shoes on the grass, and it was unlikely that he would leave mud all the way. If there are mud trails for you to follow along the way, it is likely to be a trick. If it's broken halfway, you can see where the break is, come back and report it! After Twilight finished, she looked at the footprint by the pool and said, "Be careful not to step on those mud marks when you go, I'll have to look back again, but now I have something more important to do—this footprint needs to be extracted." ”

"Extraction?" Bu Xihuan looked down at Twilight.

Twilight nodded, "People have their own habits when walking, and they are affected by their body structure, fatness, and occupational characteristics, and everyone walks with different strides and footsteps, and the footprints formed are also different. The extraction of footprints helps to infer the walking habits and occupational characteristics of the murderer, and can also extract his footprints for comparison when the suspect is found in the future. ”

"How do I extract it?"

"Lime powder, water!"

Bu Xihuan nodded slowly and glanced at the man in black. The man in black understood, and he was about to get it.

"Let her go." Twilight Qing turned her head to look at the green-clothed maid behind Wei Zhuozhi, and said to the black-clothed man, "I need you to go into the water and get the bloody clothes discarded by the murderer, there may be a murder weapon underwater." More clues to the killer may be found on clothing and murder weapons. ”

The man in black had seen Twilight's reasoning skills, and although he felt that she had a point, he stood still, his eyes like a sword.

Why do you have to let him go into the water?

Twilight understood what he was thinking as soon as she looked at him, and raised her eyebrows coldly, "Are you married?" ”

The man in black was stunned, and was asked inexplicably.

Twilight got the answer at a glance and nodded, "I don't think you're married, too." I don't know how to pity the fragrance and cherish the jade, and I don't like it. ”

The face of the man in black turned black, he clenched his fists, and endured and endured! Who isn't likable?

"In the middle of the night, you're going to let a girl dive to find the murder weapon? Well, if she's willing to go into the water, I'm okay with that. Twilight stood coldly to the side.

The man in black gritted his teeth, looked at Bu Xihuan, and when he saw him nodding, he respectfully retreated, jumped into the water with a pop.

On the shore, the green pothos glanced at Du Qing, her expression was a little complicated, and she said to Wei Zhuozhi: "Son, the slave maid will go and get what the girl wants." ”

"Bring a ladle and a pair of dry gloves." Twilight commanded.

Pothos gave her another complicated look and turned away. After she left, the little maid also followed Twilight's instructions to find the footprints, and only Bu Xihuan, Wei Zhuozhi, Na Wen, and Twilight Qing were left on the path.

Moments later, a basin of water, a basin of lime powder, a scoop, and a pair of gloves are placed in front of Twilight. The man in black was still diving up and down, and the little guy hadn't come back yet, so Twilight squatted down and scooped up a scoop of lime powder with neat movements.

Four eyes overhead looked at her, waiting to see how she would extract the footprints.

Twilight suddenly raised her hand!

The white mist was splashed in the twilight, and the four of them were caught off guard, Bu Xihuan, Wei Zhuozhi and Lu Luo, who were armed with martial arts, pointed to the ground on tiptoe together, and raised their sleeves when they retreated! Twilight raised her hand and flipped over the basin in front of her! The water splashed out, splashing the sleeves of the three people, and the lime powder on the sleeves met the water, and it was hot!

Suddenly there was a sound of wind behind Twilight! She turned around, and the man in black saw the changes on the shore and rushed out of the pool, the long sword in his hand glowing with cold light under the moonlight!

Twilight's eyes also had a cold light in her eyes, and she raised her hand to sprinkle a pot of lime powder on the ground towards the man in black! The man in black was startled, took a step into the air while dodging, and smashed into the water with a pop, and the water suddenly bubbled hot.

Suddenly there was a wind on the stone path.

Twilight's eyes flashed, and she didn't look at who it was, she turned around and grabbed the literati, the cold light flashed on her cuffs, and a thin knife between her fingers was cold in the night, forcing it to fall on the person's carotid artery, "Don't move!" ”

Bu Xihuan stopped, and saw that Twilight Qing was hiding behind the literati, revealing half of his face, sneering in the night.

Listen to her say: "I didn't have the conditions to simulate blood splattering just now, but now I have the conditions." Want to see it? ”――

Off topic -

Half of it was written last night, and half of it was written this morning. It was supposed to be sent at nine o'clock, but a truck driver passed by in the alley at the door, and the car was too high and broke the network cable.

I thought there was no network, OK, I'll wait for the telecom to fix the edge and write some more.

I didn't think about it until I wrote three thousand, sister! There seems to be such an artifact as 360 free wifi!

I'm really stupid, there is an artifact and I'm still waiting for someone to repair the network cable!

Three years of stupidity seems to be the truth.

……

This chapter is about the method of extracting footprints, and those who have studied it should be able to see it.

There are many methods of extracting footprints, and one is the gypsum extraction footprint method.

Plaster, not lime.

It's not that I didn't intend to write it wrong.,Seeing the end.,The girls should know why the young girl deliberately asked for lime, right?
