Yang Qiuchi squatted down and touched the child's carotid artery. There was no pulsation. He asked, "When did you find the child's body?"

"Just a while." The old man said in tears.

"Who discovered it first?"

An old farmer next to him kowtowed: "Report to the master, it was the first one I discovered. I came back from the field with a hoe. When I passed by, I found a child lying in the grass curled up. I thought to myself, whose child is this? I crawled into the grass and went to sleep in the winter. I walked over and called him, and found that it was Old Man Li's son, who was bleeding from his nose and mouth, and he was dead. I was frightened and hurried to the village to call Old Man Li and the others."

"Where did you find the child's body?" Yang Qiuchi asked.

"It's right here," the old farmer pointed to a piece of weedy next to him.

Yang Qiuchi walked to the weeds and bent down to check it out. The bush of thatch grew on the ridge of the field, half a person tall, and it was already withered and yellow. There was arable land around it, so I saw no one in this cold weather.

Yang Qiuchi carefully opened the dead grass and found a pool of blood in the grass, without any suspicious items or traces.

Yang Qiuchi returned to the child's body, reached out to grab the child's chin and twisted it, then carefully observed the child's clothes and pants, and then carefully took off all the children's clothes and pants.

There was a big hole on the child's forehead, and half of his face was stained with blood; his right chest was sunken inward and surrounded by purple; his right thigh and leg bone was broken, and he turned and turned to one side strangely, looking scary.

Yang Qiuchi looked at the wound on the child's forehead carefully. Suddenly, he exclaimed, leaned over and observed carefully, then reached out to grab a hair and slowly lifted it up.

Part of the hair was stained with blood on the wound, and it can be seen from the part that was not stained with blood that was golden.

Yang Qiuchi ordered Yuechan to bring a piece of white paper.

Before leaving, Yang Qiuchi had prepared some commonly used items to extract physical evidence according to his needs, such as white paper, large and small paper bags, cotton ball sticks, small cotton cloth, etc. He even made several special payments of autopsy gloves, and the middle layer was isolated by oil paper. These things were kept by the little maid Yuechan.

Yuechan quickly brought the white paper, and Yang Qiuchi wrapped the blood-stained yellow hair in white paper and put it in his arms.

After Yang Qiuchi touched the head, neck, chest, abdomen and legs with his hands, he stood up and walked on the road, bent over and walked forward slowly. Song Yuner, Nangong Xiong and others didn't know what Yang Qiuchi was doing, so he hurriedly followed.

Their convoy had already passed a distance. Yang Qiuchi called the parking lot, so the long road was empty.

Not long after walking, Yang Qiuchi stopped, looked at a short piece of wood across the roadside, studied it carefully for a while, and then came back and squatted down to look at the road surface. Song Yuner followed and asked, "Brother, what did you find?"

Yang Qiuchi pointed to the road surface, which was a string of messy horseshoe prints and several rows of shallow ruts.

Song Yuner looked at the horse's hoof prints and asked in confusion: "What's wrong? There are all over the official roads of horse's hoof prints."

"Investigating a case means discovering abnormalities from seemingly ordinary traces before finding clues left by the criminals." Yang Qiuchi said.

"Brother, you must have found clues about the criminal!" Song Yuner said excitedly, "Who killed this child?"

"I was hit by a carriage and died!"

Ah? Song Yuner exclaimed. She turned around and looked at the location of the child's body, shook her head: "No, the child was so far from the official road by the corpse. No matter how fast the carriage ran, she could not hit the child so far."

"Can't you catch it? Can't you hold it?"

Ah? Song Yuner exclaimed again, then realized: "Brother, are you saying that the person in the carriage hit the child to death and hid the body in order to cover up the crime?"

"Smart!" Yang Qiuchi praised, "That's exactly that." After saying that, he pointed to the horse's hoof prints on the ground, "Please look at the horse's hoof prints from sparse to dense, and then a large cluttered piece of marks. This is when the carriage hits the child in a mercedes and stops the horse in a handlebar, leaving such marks. There should be more than one horse."

Seeing that Song Yuner opened her eyes wide and looked at the horse hoof marks on the ground, Yang Qiuchi said, "Of course, relying on these horse hoof marks alone cannot tell that the child was killed by a carriage. You must go and check the child's body according to the injury."

Yang Qiuchi asked Nangong Xiong to pick up the short wood on the side of the road, and then everyone returned to the child's body.

Yang Qiuchi pointed to the sunken mark on the child's chest: "This is the horse's hoof trampling and leaving behind the ground. Have you noticed it? The scar on the chest is an oval semicircular blunt weapon, which is very consistent with the horse's hoof."

"The horse's hooves are trampled very hard, resulting in a fracture of the child's sternum, causing lung contusion, and causing sternum, bloody chest, pneumothorax, and may also cause blunt heart damage (this requires an autopsy to prove it). This should be the main cause of the child's death."

Yang Qiuchi pointed to the wound on the forehead of the child's corpse: "There is a tissue bridge in the wound cavity. The walls are irregular and the wound is irregular. It is a tearing wound. It should be caused by a direct impact on the horse's legs. The skull has formed a concave fracture. It can be touched with your hands, indicating that the carriage is very fast and the impact is very strong. This skull damage can cause traumatic shock to the child and accelerate the death of the child."

Yang Qiuchi has a lot of professional terms, and Song Yuner and Master Jin were confused. However, this was not the first time they heard Yang Qiuchi's strange and strange words. They gradually got used to it, and even guessed and understood it.

Then, Yang Qiuchi spread out the child's clothes and placed them flat on the ground, pointing to a mark on it: "This is left behind by the wheels of the carriage."

He held up the child's fractured right leg with both hands: "You see the injuries on this calf, which is the most telling."

"From the direction of the traces, the child should have been knocked down by a horse and trampled by the horse's hooves. Then the wheels were crushed from the child's legs, forming a skin injury on the legs - this injury is a kind of scar that is caused by the pulling of the wheel's rotational force, which causes the skin to be separated from the subcutaneous tissue in an annular shape, forming a widespread subcutaneous hematoma."

Yang Qiuchi pointed to a small tear group at the child's groin: "This kind of injury is called stretching injury. It is caused by the transition pulling of the wheel rotation force, and the epidermis tear is exposed, forming this small strip crack distributed in groups, which is consistent with the skin wrinkles."

Yang Qiuchi said: "These two kinds of injuries are typical wheel crushing injuries. It is difficult for other objects to form these two kinds of scars."

"Will someone push a cart to overwhelm the child?"

"Good question," Yang Qiuchi praised, "but it doesn't fit in terms of the injury." Yang Qiuchi pointed to the thigh scar on the child's body, "This kind of scar is very wide. If the wheel of a wheelbarrow is so wide, it is not necessary, and the second it will be difficult to push."

"There is another thing that can be proved that it was a carriage that hit the child," Yang Qiuchi turned over the child's clothes, and the back was covered with dust with fine sand and stones. "Look, the place where the child's body was found was surrounded by dead grass and soil. It was not this kind of dust with sand and stones. It should be left behind by the child being hit and being dragged by the horse's hooves and wheels after he was hit."

Yang Qiuchi turned the child's body over and pointed at the scratches on the back, buttocks and elbows: "These scratches should be caused by the carriage dragging the child's body, which can confirm my inference just now."

Song Yuner looked at Yang Qiuchi with admiration: "Brother, you are so awesome!" She turned to look at the empty official, and said: "I don't know which damn carriage hit the child and killed him. How can I find this criminal?"

"Any crime will leave traces!" Yang Qiuchi said confidently, "You can discover it as long as you are careful."

Song Yuner asked in surprise: "Brother, you have found the criminal's trace, right?" Yinya bit her, "I don't care if I hit the child, but I have to hide the body. It's really inhumane. Grab this damn criminal and deal with him heavily! Brother, tell me quickly, what is this criminal like?"

"I don't know the criminal, but I know his carriage."

"Young Master Yang, you are not at the scene, how could you know the situation of the criminal's carriage?" A girl's voice came from behind Yang Qiuchi. When she turned around, she saw that it was Bai Sumei in plain clothes. Standing next to her was Mrs. Bai.

It turned out that Bai Sumei and her daughter waited for a while but didn't see Yang Qiuchi and the others coming back. They heard that they had a murder just now. Although Bai Sumei was afraid, she was worried about Yang Qiuchi in her heart, so she and her mother came down to see Yang Qiuchi solve the case.

Yang Qiuchi looked at Bai Sumei and smiled slightly: "As I said just now, any crime will leave traces!" He took out the white paper from his arms, unfolded it, and twisted the yellow hair: "The child's hair is black, so this hair cannot be a child's, it should be left behind when the horse's legs hit the child's head."

"Yellow? Is the horse in the carriage yellow horse?" Song Yuner immediately reacted.

Yang Qiuchi nodded: "To be precise, the first horse was the yellow horse."

"Is there a second horse?" Bai Sumei also asked curiously.
