Rong Ling stood beside her, pointing to the skin opened in the red make-up's abdomen. What he wanted Liu Wei to see was not the internal organs, not the bones, not the intricate diaphragms, but the thin blood vessels inside the skin.

"Color, changed." Rong Ling said.

Liu Wei immediately looked down and saw that it was different.

She left the body half sewn just now, turning the flesh carefully with her gloves and bloody hands. Because of the dark light in the room, she also hurriedly asked for candles.

After lighting the candle and seeing clearly, she saw that the color of the blood vessels of the red make-up had changed.

The blood vessels of red make-up are light gray, not blue, not purple, but gray.

Suddenly something flashed in her mind. Liu Wei was too busy to think. She went to Lvyan's side, opened the white cloth, cut her arm and opened a piece of skin.

The blood vessels inside were normal in color, and she broke a skin on green Yan's stomach.

This time I see it. It's really gray.

She was busy rummaging around the waist of Lvyan, from the belly, waist to back. At last, she found a small mouth with the size of a thick pinhole in the position of Lvyan's waist.

That mouth is too small and has no color. Without a magnifying glass or a microscope, it's easy to ignore it if you don't look carefully. Even if you look carefully, it looks like a small mole at first sight.

But this is the wound.

And it's fatal.

"It was poisoning." When Liu Wei looks at Rong Ling again, her eyes are different: "you Do you know anything? "

Rong Leng glanced at her and said calmly, "no trauma, no internal injury, no poisoning, what else?"

"But you are so sure..."

"Since there are only three possibilities, not the other two, but the last one, why not be sure?"

Liu Wei has no words to refute. She opens her mouth and wants to say something more. She can't say it.

At last, she sighed. She sewed up the wound with red makeup and said, "I need to go back and look through the medical books, blood vessels, and gray. I remember where I saw it and what poison would cause this effect?"

After finishing the body, Liu Wei took off her gloves and hurried out.

After washing her hands, Liu Wei is in a hurry to turn over the book.

But just out of the yard, suddenly a short child appeared.

Ji Bing is here to thank you. He should have said it when he met in the morning, but he didn't say it at that time. He went back to think about it, and then came again.

Just now I saw Liu Wei busy in the morgue. He didn't bother. He had been waiting by the arch for a long time.

Slowly wriggling his fingers, his mouth pouted and pouted. At last, he finally opened his mouth: "yesterday, yesterday Thank you for saving... "

"Get out of the way."

Not waiting for Ji Bing to finish, Liu Wei, who is in a hurry, has waved his hand and flicked the light floating child to the side, leaving in the wind.

Ji Bing looks at the back of her leaving, her eyes are round.

The child didn't expect that this is said to be his cousin's Qing Juan man meeting! Here! Ah! No! Courtesy! Appearance!

Rong Leng saw Ji Bing. His eyes were circling around the child, and he didn't plan to stay too much.

Ji Bing stopped him: "wait, wait..."

In fact, Ji Bing was worried. After shouting, he found that his uncle didn't stop. Another man beside him looked back at him. He couldn't help but feel nervous.

Licked the lip, he hesitated: "I, I'm here to thank you."

Rong Leng raised his eyebrows, but there was no sound.

"My 16th uncle asked me to come, not my own, but But yesterday, indeed, thank you very much... " He recognized the man he had seen last night. Ji Bing gave him a polite nod.

Rong Leng says "um" with patience. He finds Liu Wei has disappeared and sighs a little.

Ji Bing ran up again, took out a small porcelain bottle from his arms and handed it to him: "this is my own medicine. It can be used in an emergency fashion. It's a thank you and a thank you."

Rong Ling looks at the porcelain bottle and squints: "you can cure. Do you like to give medicine to others?"

Ji Bing was stunned for a moment. He probably said the cousin and pouted: "my medicine is different from others. It's not a critical moment. It's not available."

Look at the child to say seriously, let Leng reluctantly take over the porcelain bottle.

Ji Bing found that although his face was very serious, he looked very fierce and fierce, but actually he was OK. He couldn't help saying: "I don't know if he told you about my five senses. I have a keen sense of five senses, especially poisons. My medicine is more or less poisonous and can't be taken randomly. But at the critical moment, it's definitely more effective than those ordinary Chinese medicine. Don't you Look down. "

Rong Leng receives the bottle into the sleeve bag, turns back and plans to leave, suddenly gives a meal, and then turns to look at the child: "poison?"

Ji Bing nodded modestly and didn't make himself too proud: "even if it's nearby, I don't know the poison in the world."Look at his self-confidence, let Leng ponder and ask: "a kind of poison that enters the human body and causes discoloration of blood vessels, do you know?"

"Blood vessels?" The child doesn't understand the word.

Let Leng explain.

The child understood, frowned and touched his chin, and said for a moment, "if according to what you said, the thin meridians under the human skin are called blood vessels, what will make it change color, I can only think of the fear of snakes, is it gray?"

Rong Leng's eyes stopped for a moment: "afraid of snakes?"

"A kind of poisonous snake, which lives in the swamp, usually has poison in its teeth. Otherwise, it has poison in its whole body. Skin, meat and snake gall are all poisonous. However, the blood vessel discoloration you said should be snake gall. Some medicines need to be afraid of snake gall when they are developed. There is also a dry snake gall in my room. It was collected by the villagers in the mountain before I came to Qingzhou. Would you like to have a look?"

Rong Ling nodded, "OK."

Ji BingDao: "you wait for me here. I'll come as soon as I go."

With the child finished, he pedaled and ran out.

When Liu Wei ran back to the post house with a lot of books, he searched the East and the west, and Ji Bing had cleverly taken the dried snake gall and put it to Rong Leng's hand.

"Don't touch it with your hands. Wrap it in a cloth." Ji Bing reminds him to hand him a handkerchief.

Rong Ling wrapped a handkerchief, took out the gray black snake gall in the small box, and asked, "is there any name for this poison?"

"I don't think so." Ji Bing said: "fear snake is not a rare snake. It is found in many hot and humid forests. Usually villagers catch it and sell it to the pharmacy in the city. This snake venom is mostly used to make rat medicine."

"Rat poison?"

"Yes, it's the most common kind of rat poison, but you say it will make blood vessels gray. The poison must be very heavy. The usual poison is discoloring the skin and flesh. It's gray. As far as I know, it's the only one. How? Is someone dead?"

Rong Leng looked at the child and said, "two women."

Ji Bing nodded and said, "the one who killed them must be a woman."

Rong Ling looks at him.

Ji Bing naturally said: "isn't this obvious? Only women like to use rat poison arsenic, which can be bought in pharmacies. Those who have a little experience will not be so blatant." Said and asked: "where is the wound?"

Rong Leng said, "back waist."

"Is the wound big?"

"Silver needle size."

Ji Bing nodded and determined: "the murderer must be a woman. The needle, thread and other things are women's favorite. Someone must have bought the snake gall. Insert the silver needle into the gall and soak it for more than three hours. When the poison is saturated, use the silver needle to kill people. But there is still a problem. Although the snake gall is poisonous, the pharmacy can usually buy the ready-made snake gall. We know how to use it It is not convenient for the murderer to have a good understanding of vipers and know a little about medical skills. I prefer the former. "
