"You...... My daughter's family can say such swear words! Jiao'er was choked and hurriedly came over to help.

Su Liuyu took off Zhuang Mengru's clothes, and saw that the small red rash on her body had already shown signs of disappearing.

"After Zhuang Mengru was poisoned again, did there any change in these red rashes?" Su Liuyu asked.

Jiao'er thought for a while and shook her head: "Miss's body is cold, her forehead is hot, and the slave maid only cares about cooling down Miss, and she hasn't noticed these rashes." ”

"What kind of tonic did Zhuang Li send Lingxin last night?"

Jiao'er pointed to the cup next to her and said, "It's the thousand-year-old ginseng soup that the concubine gave her last year." ”

Su Liuyu almost didn't spit out a mouthful of blood when she heard this.

Why did you give her ginseng soup again, and return the thousand-year-old ginseng!

"Blame me, I didn't make it clear to you yesterday, Zhuang Mengru's body is too weak now, and she can't eat these things that are too supplemental, so she can only slowly adjust and replenish them for a long time." After Su Liuyu finished speaking, she went to look at the cup.

Jiao'er took out a silver needle wrapped in cloth from her arms and said to Su Liuyu: "You said today that the second miss was killed by the eldest lady, I specially tried this soup with a silver needle, it is not poisonous at all!" ”

After speaking, he put the needle in the soup for a few more seconds before taking it out and showing it to Su Liuyu.

Su Liuyu looked surprised: "The silver needle is not a poison that can be detected, and the silver needle will only turn black after encountering arsenic/frost." ”

In the past, the means of drug production were not sophisticated, resulting in arsenic/frost accompanied by more or less sulfur and sulfide, when sulfur and silver came into contact with each other, there would be a chemical reaction, resulting in a layer of black "silver sulfide" on the surface of silver.

But the poison in Zhuang Mengru is so clever, and the ingredients are naturally different from arsenic/cream.

In other words, as long as silver requires sulfur content, whether toxic or not, it will turn black.

It's just that Su Liuyu doesn't understand, now that she can make such a high-grade poison, including the moment of ecstasy in her before, it must also be a poison that can't be tested with a silver needle, why is it still popular for people to use silver needles to test poison now?

"If you want to set up a blame, naturally you have a lot of quibbles!"

Su Liuyu took a little soup, put it in his medicine box, and said, "You use a silver needle to test Zhuang Mengru's blood to see if the needle will turn black." ”

"You're really a femme fatale!" Jiao'er's emotions suddenly became excited, "Miss is already like this, you still want to coax me to torture Miss with this needle!" ”

"You use your cement pipe brain, can't you try the blood that Zhuang Mengru vomited?"

Although no one told her that Zhuang Mengru had vomited blood, it could be seen from the little blood splatters on the sheets that Zhuang Mengru was pillow that she must have vomited last night.

No matter what the dealer says, it's everyone, she got swill here again yesterday, the sheets and quilt covers must have been changed a long time ago, and the blood stains can't be vomited after eating those medicines at noon yesterday, then it will only be vomited after poisoning.

When Jiao'er heard this, she immediately went to find the handkerchief that wiped Zhuang Mengru's mouth, and rubbed it on the cloth with a silver needle, but there was really no reaction on the silver needle.

"Well, did I lie to you?" Su Liuyu clasped her arms and looked at Jiao'er, "Whether it is the government doctor or the imperial doctor, they should have told you that Zhuang Mengru was indeed poisoned, right?" But why can't the silver needle be detected in her blood? ”

But in this pot of soup, there may really be no poison.

After all, the cold poison is such a rare poison, and it is so strong, there is no reason for Zhuang Li to leave such a big pot here.

"Where was the bowl where Zhuang Mengru drank soup yesterday?" Su Liuyu looked around the room and didn't see it.

"That bowl is also a purple jade grape bowl given by the concubine Niangniang, and after feeding the soup to the young lady, it was taken back by Sister Lingxin."

It seems that this poison is hidden in the bowl?

"What about the spoon for the soup?"

If the poison is on the bowl, the spoon will definitely be stained with some of the soup.

"The spoon is a purple jade spoon that goes with the bowl, and it was also brought back by Sister Lingxin." Jiao'er said truthfully.

Su Liuyu nodded.

It's unrealistic to go now, although Su Liuyu really wants to know the ingredients and principles of this cold poison, but she can only give up.

She took out the silver needle and ventilated Zhuang Mengru first.

Because the cold will make Zhuang Mengru gradually difficult to breathe, and finally suffocate herself, it is not so much that Zhuang Mengru is nervous and watching herself being buried alive and suffocated to death, it is better to say that this is an extended version of the suffocation death process.

Because it will cause Zhuang Mengru to lose her vital signs, her body is cold, and her limbs are stiff, but she still has subtle breathing.

It's just that the breath is too weak for a human finger to detect the breath.

So Zhuang Mengru will be sent into the coffin, live inside to feel the nails on the coffin, and then be buried and buried alive.

On the one hand, it is the effect of poison.

On the other hand, it is the loss of oxygen and the lack of oxygen that causes death.

"Jiao'er, you go to the small stove in the kitchen to find a clean small pot and boil this into soup." Su Liuyu took out the dung of the Xuancai crow from the small cloth bag and handed it to Jiao'er.

Jiao'er looked at the black lump wrapped in leather cloth, and there were many small pure black particles in it, and asked, "What is this?" ”

"Add less water and make it thicker, but don't boil it too much. Until it gets thick and sticky/greasy and you can't see the little particles, then bring it to me. Su Liuyu ignored Jiao'er's question and continued to instruct.

Jiao'er was reluctant, but she went anyway.

It's just that she didn't go by herself, but explained to the other maidservants, and she continued to stare at Su Liuyu in the room uneasily.

Unlike the usual crows, the crow lives alone, and can only be seen congregating during the mating season, but there are not many of them.

It was pitch black, except for a few feathers on the top of its head and tail that were somewhat colored in the sun, which was the legendary multicolored black.

It feeds on poisonous insects, and when the snow covers the earth in winter, the crow, which has lost its food source, will go to the cliffs to eat a fruit called the withered leaf fruit, which grows on the cliffs and is almost impossible for humans to reach.

However, the dead leaf fruit is the best tonic, after the special intestinal digestion of the Xuancai crow, the excrement has a miraculous use, and it is an extremely precious medicinal material.

Those little particles are the pits that can't be digested.

But in the end, it is feces, which is more or less sour.

Su Liuyu took out the materials she had mashed and poured them into the innermost part of Zhuang Mengru.

Jiao'er asked uneasily, "What did you eat for my young lady?" ”

"If you don't believe me, don't let people ask me to heal, if you believe me, don't talk so much nonsense, have more eyesight, and help me help."

"Naturally, I don't believe you, you and my young lady have always been at odds, how could you be so kind to save her?" Jiao'er immediately pointed at Su Liuyu and said, "What's more, Miss will become like this, and you are also harmed!" ”
