Lu Qingrong suddenly asked, "Do you still have those medicinal materials and medicinal residues brought by the two aunts the year before last?" ”

Lu Zhu was a little confused, and it took a while before she remembered that she was referring to the medicinal materials that Aunt Chen and Aunt Wei had brought before Mrs. Jiang died of illness, as well as the leftover medicinal residue.

"Keep it all as you tell me." Green Bamboo Returns.

"Go get it!" Lu Qingrong immediately ordered.

Although Luzhu was puzzled, he didn't ask much and went directly.

Lu Qingrong sat quietly alone, with thousands of thoughts in his heart, and he couldn't figure it out.

Yesterday, Xu Yizheng's advice, as well as the conversation between herself and Luzhu just now, kept echoing in her ears, making her realize a problem that she might have ignored before.

She once compiled the medicinal materials used by Mrs. Jiang that day into a prescription, asked the doctor for this, and even looked through the medical book for a while, but never found the slightest problem with this prescription.

Now that I think about it, I must still have been negligent......

At this time, Luzhu had already returned with two medicine bags.

Lu Qingrong took it carefully, put it on the small table in front of him, and looked at it separately.

One of the packets is the remaining herbs that have not had time to boil, and the other packet is the residue of the medicine after boiling.

The packet of medicinal herbs, although more than ten years have passed, looks extremely dry, but it is still well preserved, at least the shape and color are very real.

It is precisely because of this that when Lu Qingrong sorted out the recipe before, he used the medicinal materials in this bag, and did not move the other package of medicinal residues that were air-dried after mold.

At that time, she took it for granted that this one was what it looked like before boiling medicine. One is the appearance after boiling the medicine, which is originally the same thing, and it must be which one is easy to distinguish which one is used!

As a matter of fact. As cautious as she was, she was worried that the two aunts' expressions were wrong, but they probably compared them, but they didn't find any difference.

However, this time, Lu Qingrong was many times more careful.

I saw that her gaze kept moving between the medicinal herbs and the medicinal residue, seriously contrasting.

Lu Zhu was a little puzzled on the side, so he also watched it together. But he never got to the point.

"Madame, what are you looking at?" Midoritake finally asked.

"Look at the difference between the two......" Lu Qingrong muttered, his eyes still not stopping.

Green Bamboo got a hint. But I still can't see why.

The same is true for Lu Qingrong. She even began to wonder if her premonition was wrong......

Just as he was about to give up, Lu Qingrong suddenly noticed a small difference.

In that packet of dregs, the proportion of a certain flavor medicine. It seems to be very different from the other package of herbs.

There is a taste of red ginseng in the prescription. Lu Qingrong still remembers it because he has studied that recipe for a long time.

At this time, I noticed that the residue looked like a slice of red ginseng, and after careful comparison, it was found that it was many times more than the proportion of red ginseng in the medicinal materials!

Lu Qingrong is also not sure whether this is related to Mrs. Jiang's death.

After all, it's just red ginseng, even if you use a little more, it won't be lethal......

"Let's pick out all the red ginseng in the residue first!" Lu Qingrong gave the order. and the green bamboo together.

When all the ginseng slices in the medicine residue are picked out and placed in one place. Lu Qingrong suddenly noticed something unusual.

Although the shapes are similar, they are all the size of a little finger nail, thin sheets, but when you compare them carefully, there are subtle differences in color.

Green bamboo also saw the clues, and couldn't help muttering: "It seems that the color is dark and light...... Could it be that it is not from the same ginseng? ”

Lu Qingrong's intuition told him that it might not be so simple.

She picked up two pieces of ginseng of different colors and looked at them for a long time.

I saw the one with a slightly lighter color, the skin was dark brown, and the section was only slightly yellow, because it was the residue after surviving, Lu Qingrong guessed that this section might have been white.

Then it's probably not red ginseng......

Lu Qingrong immediately took out some of the two kinds of ginseng slices in the medicine residue, and instructed the green bamboo to wrap it and take it to Mo Nan, or according to the method last time, quietly go out of the house to find a pharmacy to ask.

In the evening, after Mo Nan came back to report, Lu Qingrong was filled with grief and anger in his heart.

She forcibly calmed herself down, and personally took someone to the pharmacy in the front yard of the Hou Mansion......

Jiang Xuan came back very late today.

At the moment, Jiang Xuan tiptoed into the inner room, for fear of waking up Lu Qingrong.

But he didn't want to, at this time, Lu Qingrong was still staying in the dimly lit inner and outer rooms, sitting precariously waiting for him.

Jiang Xuan felt guilty, but also with a hint of blame: "They all said that you should rest earlier, why do you insist on waiting for me......"

In the middle of his words, when he saw a few things on the small table in the middle of the agarwood arhat bed, he suddenly stopped.

Jiang Xuan also remembered the two packets of medicinal herbs and medicinal residues, so he naturally recognized them at a glance, and at this time, there were two things like account books next to them, with Lu Qingrong's expression full of calm...... A chill instantly rose in Jiang Xuan's heart.

"What problems did you find?" Jiang Xuan asked in a deep voice.

Lu Qingrong took a deep breath and said, "We were negligent before, and we didn't pay attention to that bag of medicine residue. Today, by coincidence, I found out that the medicine residue was actually different from the medicinal herbs, and there was an extra medicinal ...... in it."

"What's more?" Jiang Xuan's voice trembled slightly.

"Ground cotton roots, also called Jiuxin grass, are not very used, and they are poisonous." Lu Qingrong was concise and to the point.

"So...... When my mother was poisoned, she died ......"

Jiang Xuan's voice was extremely soft, but it seemed to have exhausted all his strength.

I saw him clenching his fists and being silent for a long time before he spoke again: "The medicinal materials I grabbed are fine, but when I boiled them, there was an extra poison, so it can be seen that this poison must have come from the house!" ”

"The root of the ground cotton is not a poison, as long as it is used properly, it is also a good cure, but the dose of the decoction used by my mother is too large...... I went to the pharmacy in the front yard today, and there were cotton roots there. Lu Qingrong picked up the account book above, "The purchase and use in the pharmacy should all be recorded in detail here......

Hearing this, Jiang Xuan understood that this record must be gone.

But he still took it, looked through it a little, and sure enough, he found that there were a few missing pages, which were obviously torn off intentionally, and from the time before and after, the missing pages were the months before and after Mrs. Jiang's death.

Lu Qingrong was afraid that he would be in a hurry, so he hurriedly continued: "But compared with the time when I bought the cotton roots, there are obviously a lot less. So I went to the archives of the prescriptions of various hospitals. On the eve of her mother's death, Qinyi Yuan once used a prescription to treat Mrs. Wu's long-term cough, which contained a small amount of cotton roots......"
