Among them, Yuecao Hall could be counted as an industry that protected one's family's foundation, and each year, Marquis Mansion accounted for at least thirty percent of the household's income. The branch family had long since left the capital, and their reputation was also quite good in the south.

He had the foresight to know that the three Medicine Hall s that were ahead of the capital had opened a branch family in the southwest. It was a good thing that they had developed this way. The cause of the incident was an old squire from Xi'an Prefecture. Because of his sickness due to her age, she could be considered to be with medicine all year round. One day, due to a sudden attack of cough and asthma, she went to the Yuecao Hall and grabbed some medicine and brought it home. Not only did she not recover from his sickness, but she also died from frothing at the mouth.

Then again, even if there wasn't any power behind it, they wouldn't be able to do it too big. Everyone knew that it was for mutual benefit, and since Yuecao Hall had a good reputation, most people would prefer that the old squire would live to the point of sickness and death. Just like this, under the biased judgement of the officials, the old squire's sons accepted the fact and went home to divide their property in grief. As a result, this matter was suppressed.

However, something similar happened in the Chengdu residence soon after. This time, the young master was not the same as the old squire; he was the son of the young master of Shen Family, the son of the Sichuan governor Shen Maotian, and the younger brother of his concubine, Shen Zhui.

Shen Maotian was not just this son, but this young master could be considered to be an old man, and was also his most beloved darling. Originally, he had some child dysentery, and later when he asked for medicine, he was able to enter the Yuecao Hall, and this young master did not immediately die from the medicine, and instead died after drinking three batches of medicine. After the doctor's inspection, he suspected that there was a problem with the medicine, and thus died.

This kind of Yuecao Hall naturally could not be easily dismissed by a doctor with a few words. Who knew if the doctor was mistaken, or if he had died due to some other reason, or if he had eaten something by mistake, or if there was a dirty incident in the backyard, or if he had specially asked for a coroner to examine the corpse, but the final conclusion of the autopsy was that he had been poisoned.

Of course, being poisoned cannot be determined as there was a problem with the herbs. After all, the medicine shop was open for business, who would want to destroy a signboard for no reason? Furthermore, there was no enmity with a little kid like Shen Family, why did you harm him? One was their local emperor's Shen Family, the other was the Marquis Anfeng's palace that held a lot of power in the capital. They could not afford to offend any one of them, yet they could not let go of their Shen Family, which was really hard to deal with.

Later on, the officials checked the root of the problem and determined that the herb was the one that killed the young master of Shen Family by adding him into the Intestine Severing Grass. This time, the Shen Family had exploded, and no matter if it was on purpose or not, since the herb was bought from your medicine store, your Yuecao Hall was responsible.

He was not afraid of who was behind the Yuecao Hall, and directly closed down a few local branch stores. In the Southwest region, the Shen Family was like an emperor who did not care about anything, and furthermore, he was in the right, so you could say that he did not leave any face to the Marquis Anfeng Palace.

The entire nation's branch families were affected by the incident with the Yuecao Hall. If the medicine store had taken someone's life, no one would dare to buy another medicine, otherwise, it would be impossible for them to not be affected. Other than the main family in the capital, who would be able to continue sitting here under the pressure, the rest of the families would have chosen to close their doors due to the pressure.

When Bai Cao came over to talk about this matter with Xie Jingxi, she was puzzled, "Logically speaking, Medicine Hall like the Yuecao Hall should have a great scale, with experts inspecting all the medicinal ingredients that enter and exit, and the medicinal ingredients that are in contact with are very mature, how could they be so easily poisoned without knowing?"

Xie Jingxi was very sensitive to this matter, from Xie Jingqi's difficult situation to her big brother's early death, all of them were because of the herbs, to Wuhen who still did not have a clue, and to his current Shen Family that was at the peak of its power, which was even related to the battles in the imperial court, it was all going to be very troublesome no matter what. Just like what Bai Cao had said, this matter seemed to be a small medical incident, but it was extremely strange.

Xie Jingxi said to Bai Cao: "Could it be that it's a competition between several clans' Medicine Hall? For this kind of thing, other than the merchants being able to deal with it, ordinary people would not even think of starting from the medicine store." As for why Shen Family was so unlucky, then it might involve another layer of deeper meaning.

After all, the matter of involving the inner courtyard of the Marquis Mansion was still a little far. It was undeniable that if one mixed poison with medicinal herbs, it would either be one of their own, or the source of the medicinal herbs would have a problem. Regardless of which aspect it was found to be from, it was still a huge project.

As far as I know, not only one or two families have their eyes on that piece of fat, the Yuecao Hall is located in the southwest of the Northwest, and it is hard to say what kind of families would be interested in that piece of fat. "Su Yun said.

Xie Jingxi asked again, "Have you found any problems with the medicine?"

If even the master of a Yuecao Hall could be tricked, then it must not be an ordinary method. This seems to have the same effect as the things that happened in the Marquis Mansion, perhaps, he might be able to find out the trick in the Marquis Mansion if he followed this line.

Bai Cao said: "I don't know the specifics, I only said that they were poisoned by the Intestinal Severing Grass, and there were a few that died from eating the medicine, and I found out that they were also poisoned by the Intestinal Severing Grass, but there is clearly no Intestine Severing Grass within the medicinal ingredients, which is truly a little outrageous."

thought for a moment, then asked: "Just now, you said that Young Master Shen Family has some sort of illness?"

"Oh, it's infantile dysentery."

Xie Jingxi pondered on the possibility of a poison appearing within the prescription, "I'm wondering, could it be that the poison was dipped in the poison? If there were no other ingredients, then the most likely reason would be that the poison had appeared within the prescription beforehand.

Bai Cao suddenly realised and opened her mouth wide, "Madam is right, why didn't I remember, it was indeed true!"

"Since it's like this, we'll have to trouble you. Go and check where the Yuecao Hall medicine came from, and whether there's any source of medicine in the green pouch. Once there's any source of medicine, stop selling it immediately."

Bai Cao's face immediately became serious, "Luckily Madam reminded me, I will do it right away!"

"Don't worry, I still have something to ask you." Xie Jingxi pulled Bai Cao back again, "There's no need to be in such a hurry, if it was deliberately aimed at Yuecao Hall, other families would not see the presence of poisonous medicinal herbs, it would be very easy to expose ourselves, but just in case, we have to be careful, just now when I thought about it, there's a possibility that the problematic tasting medicine is Xia Mu Grass, if you don't care about the source of the poison, you should pay attention to the taste of the medicine."

Bai Cao nodded, "I understand Madam."

"And the medicine I asked you to buy at Changchun Hall, do you remember?"

Bai Cao naturally remembered that the medicine was not easy to buy. She had gone to several stores but finally bought one from the Eternal Spring Hall. However, she did not know what Xie Jingxi's intentions were.

Xie Jingxi explained: "Those medicines are unique to the Northern Lands, and because it's not easy to obtain, it's not so easy to buy them. I started to suspect that the Eternal Spring Hall originated from the Northern Lands, so they should have their own independent medicinal ingredients. As for the relationship between them and the Yuecao Hall, I have not thought of it yet, but I think if you want to investigate, you should start with the medicine dealers from the Northern Territories."

Receiving Xie Jingxi's instructions, Bai Cao started to look into the matters regarding the ingredients. In the blink of an eye, it was Lady Zeng's birthday, and it was rare for Xie Jingxi to be able to do such a thing.

"The concubine that Second Young Master married is actually quite capable, it also allows you to have some free time."

Xie Jingxi laughed for a long time, his face was stiff, "It's quite rare."

Lady Zou looked at her, "You are quite open-minded, and I see that Aunt has treated her pretty well. I believe she has some methods to win over people, you should be more careful."

"Oh, so this is Grand Mistress. His reputation is indeed well-deserved, he sure is good-looking."

Just as they were talking, a lady walked over, interrupting the conversation between Xie Jingxi and Lady Zou. Xie Jingxi was unable to recognize her at that moment, and even the Lady Zou spoke first: "Mrs. Zhang, long time no see, and you're still in high spirits."

The lady that followed should be their family's elder, Zhang Yushi. Xie Jingxi said: "Mrs. Zhang, please honor me, Miss Zhang is the one who brings out the water phoenix hibiscus, it is so fun today, Mother is here too."

Zhang Yu Shi was expressionless, she did not even look at her, after Mrs. Zhang greeted her with a few strange words, she led Zhang Yu Shi in, Xie Jingxi could not help but be puzzled, when did she offend Mrs. Zhang Family, it seemed like they were not in a relationship?

Lady Zou snorted a laugh at the side, "I knew you wouldn't know."

Xie Jingxi nodded honestly, she had only been away from the noble circles in the capital for a few months, and she already could not keep up with them, so she was truly confused.

"There are a lot of things that you probably don't know about when you weren't in the capital for the past few months." Lady Zou said softly: "Second Prince has already reached the age of marriage, but don't you know that there are many people in the capital who have ideas? I heard that Imperial Noble Consort Shen praised Lady Zhang for her looks, and Zhang Family was moved just like that, I won't tell you about the rest, but you probably understand, right?"
