One of the most vicious is to use five silver needles to stimulate five key points at the same time, which can make people's various organs slowly fail until they are completely useless, and the human body presents a state of natural old age.

If you don't use special techniques, no matter how powerful Rao is, he can't find out the real cause, and he can only find out that the other party's body is weak, and the medicine is difficult to repair.

If you use this method to deal with your own enemies...... It couldn't have been better.

Cui Yan learned it immediately, and of course, she also paid a little price - the codex she spent a morning sorting out had to be given to Ding Chunqiu after the production of this batch of medicines, and at the same time, she also promised Ding Chunqiu that she would take the time to give him a perfect version.

This can't blame Ding Chunqiu for being such a treasure, he is a master of medicine, but, with his identity and status, the drugs he uses must be the best and most precious, and he also knows and understands the subtle toxicity of ordinary drugs, but he is not proficient.

Although his grasp of pharmacology may not be as good as Cui Yan's, his refining skills are far above Cui Yan.

Most of the strong poisons taste extremely domineering. Therefore, many poisons are made with alcohol as a solvent or added to incense to mask the smell of the poison itself. And most of the poisons made by Ding Chunqiu have extremely light tastes, and there are a few flavors or even completely colorless and tasteless powders, even with a sensitive nose like Cui Yan, they didn't notice it.

It is rare to be able to overpower Cui Yan, Ding Chunqiu suddenly became arrogant, "Little girl, I can only call it poison, you can only use it to quench the knife and soak the sword." ”

Cui Yan twitched the corner of her mouth, looking at the big pool of green in the basin, and she was also a little disgusted.

She couldn't help but ask, "Senior Chu, Senior Ding, your two of you have such powerful medical skills, why did you come to this small inn to help me refine medicine?" ”

As soon as Cui Yan's words came out, the three people in the room all pointed their ears, and Chu Jiangnan and Ding Chunqiu directly blackened their faces.

This girl, which pot is not opened.

"For the Chinese New Year, who doesn't want to stay in the village, roasting over a small fire, eating small meat, and drinking small wine...... When who wants to come out and blow the cold wind and run around tired? It's not all because of your good-looking Xiao Yu! In the last sentence, Ding Chunqiu almost roared.

Cui Yan wiped her face, wiped the saliva off her face, and silently took a step back.

This old man, when he first saw him, looked like a master, but when he got acquainted, he was not the same thing at all, he was completely a bandit.

Cui Yan said coldly, "I don't know at all, don't be angry with me." As for my father-in-law, if they provoke you, you can go to him to settle accounts. ”

That guy is not a soft persimmon, Cui Yan is not worried that Xiao Yu will suffer at all.

Ding Chunqiu: "......"

What to do, he really wants to beat people. However, the other party is a girl, and she is several rounds younger than him, and it is more than enough for his granddaughter.

Chu Jiangnan said, "A few years ago, a first-level killer of the Shura Sect found my senior brother and sister, and he had to sell my senior brother a medicine for a marriage of 100,000 taels of silver......

Chu Jiangnan took out a porcelain bottle from his sleeve robe, and inside was a brown pill. Cui Yan narrowed her eyes...... She recognized the pill.

It seems that it is really Xiao Yu's handiwork.

She also noticed the time point that Chu Jiangnan said, years ago. At that time, even the He Lin case did not happen, but Xiao Yu made such an arrangement......
