Xiao Yichen was originally teasing the little woman who lost her temper all day long, and she never thought of really taking advantage of her in front of so many people. At this moment, she just glanced at Cheng Cheng who was huffing with deep meaning, and sighed deliberately contrivedly, and then turned to Lu Tianshui in her murderous gaze and said, "Then it's troublesome." ”

After speaking, without waiting for others to speak, Xiao Yichen raised his right hand and pointed to Lu Tianshui's chest, and then said: "First of all, we will find a very strange place from the wounds of the deceased, that is, the ribs of the chest cavity are turned outward. In other words, if we want to kill a person, whether it is stabbing, slashing, smashing with a sharp weapon, even if the force is strong enough to break the ribs, then the broken bone should be dented or pierced inward, and it is impossible to flip outward. ”

Everyone didn't have any opinions on this, and even Lu Tianshui nodded slightly in agreement.

After a slight pause, Xiao Yichen continued: "Then, to cause such a wound, it can only be a force from the inside to the outside. It is ruled out that a knife may be inserted into the gap between the ribs and then broken outward. Because the marks of the wound can almost certainly confirm that it is a one-time wound, it is impossible to have such a wound unless several knives are inserted at the same time and forcefully broken outward from the upper and lower ends. In the end, it can be ruled out that it was the result of the explosives, because from the photographs, it can be seen that the fracture of the muscle was caused by a strong outward pull, not a fracture caused by the impact of the explosives. ”

"Well, that's right, our technical officer has also determined that this is a broken wound after a strong pull. Lu Tianshui nodded in affirmation.

"Now that the basic methods have been drained, there is only one left. That is, the murderer used a strange weapon, or rather, it was simply his own hand. Speaking of this, Xiao Yichen raised his right hand again, and after opening his palm, he slowly gathered the five fingers together with the fingertips as the core, forming a conical palm shape like a pickaxe.

Immediately, I saw Xiao Yichen put his five fingertips together against the gap between the ribs in the heart of Lu Tianshui's chest, opened his mouth and said: "Insert your hand, or a similar weapon, into the bone gap of the deceased's chest under strong force, and then open your fingers to form a claw, and finally grab the heart, and pull it out forcefully." Under the action of speed and force, the first two upper and lower ribs of the deceased were forced to squeeze open in two directions, or simply broken horizontally, and then because of the claw-like palm recovery, they were easily lifted outward, forming the current open large wound. The advantages of this are, firstly, that the heart will not be punctured by the ribs, and secondly, it can keep the heart intact when it is scratched out. This murderer is likely to use this method to kill people in order to get the heart. ”

"So that's the case!" Lu Tianshui and the others nodded vigorously, and even began to pick up their palms and experiment on themselves with the posture provided by Xiao Yichen.

"However, even if you know how the murderer kills, it doesn't prove that he is not a murderer!" Cheng Cheng studied for a while, then frowned and pointed at Mu Xuanlang, "He is a werewolf of the demon clan, and his nails can be retracted, isn't it more able to cause such a wound?"

"I said, you have a grudge against me!" Mu Xuanlang couldn't bear it anymore, and opened his mouth and shouted: "People whose nails can be retracted, grab a lot of them in the demon clan." Even among monks like you, there are not a few who can do it, so why don't you doubt them?"

"Hmph, if you can tell who has been to this room, of course I will go and arrest it and torture it!" Cheng Cheng snorted disdainfully, as if he was about to start bringing the topic into the ditch again.

Xiao Yichen waved his hand and separated the two who looked at each other unpleasantly like cockfights, and then said: "After listening to me, you can believe that this kid can't do this." ”

These words immediately focused everyone's attention on Xiao Yichen's handsome face. I saw him poke his finger on Lu Tianshui's chest again, and then said: "What I want to prove to you is the bloodstains at the scene, and it is destined that this kid will not be the murderer." ”

"Bloodstains?" Lu Tianshui was stunned for a moment, and subconsciously looked at the bloodstains everywhere in the room.

"Yes, bloodstains. Xiao Yichen said with confidence: "You see, to achieve the kind of heart method I just said, no matter what posture you use, the length of an arm is the maximum distance that the murderer can reach when attacking the deceased." In other words, even if this murderer lies on the back of the deceased, stretches his hand to his chest from behind and pulls out his heart, his cuffs and palms will definitely be stained with blood sprays. And, look at this room. The blood stains on the ground have been submerged in the blood flowing out, and it is difficult to distinguish the traces, but the blood stains on the walls can still be seen that the deceased who was at the desk at the time, after being attacked, the blood stains sprayed out were obviously blocked by something, so they were formed, there were many on both sides, and the middle was relatively rare. From this trace, it can be seen that the murderer was very fast, and after the heart was removed, he was only hit by the initial blood spray, and then he had already jumped or ran away. It's just that the blood jet speed after that is no longer as strong as it was at the beginning, so it will form the current style, although there is, but it is not very dense. ”

"That's right, if you explain it like this, it's true!" Lu Tian subconsciously touched the wall around him, and after carefully observing the bloodstains, he pointed to the section closer to the ground and said: "There are more below, and there are fewer above, obviously at the beginning, the blood with the strongest strength was blocked by the murderer's own body, and then because the spray intensity was not enough, a large number of it fell to a lower position." ”

After discovering that Lu Tianshui had confirmed his statement, Xiao Yichen smiled and pointed to the tablet that he was still holding in his hand and said, "But judging from the flat image you just showed us, this kid didn't see any blood on his arms, palms, clothes, pants, etc., whether he went in or came out. Even where he passed, you must not have found any bloody footprints. If he is really a murderer, in just ten minutes, he has to kill six people and completely dispose of his own bloodstains, then how did he do it?"

"This, this ......" Cheng Cheng also seemed to have realized that blood stains were an unavoidable problem, but she still refused to admit defeat and said: "Maybe, maybe their wolf demon has some special way to clean up the blood stains!"
