After Yun Jingyao left, the prime minister decided to investigate the poisoning that day, and they investigated all the pharmacies that had contact with the Three Princes' Mansion at that time, and finally targeted a store selling supplements in the west of the city.

This shop specializes in selling supplements, whether it is a medicine that can be said or cannot be said, the store has everything in the store. So the three princes also prefer to come here. After locking the target, Su Mujin and Prime Minister Su went to the shop together and decided to find out.

Su Ruyun got up early in the morning and rushed to the Prime Minister's Mansion, originally going to find Su Mujin to be unlucky, but she didn't see her, so she asked, "What about the slut?" ”

The subordinate stood aside and said tremblingly: "I went out with the master early in the morning, and the master specially instructed that if you ask, Miss, let me tell you, don't go to them." ”

It's good not to listen to this, but it's infuriating to hear it, she gritted her teeth, "What do you mean?" Stop taking me into account so soon? Don't let me go, I'm going to go! ”

Chen's Pharmacy.

Su Mujin entered the door, a strong smell of medicine came to her face, she frowned, and looked around, the medicine here is tantamount to a modern husband and wife love shop, there are all kinds of strange medicines.

At this moment, a shopkeeper came over and said with a smile: "Do you have anything you need?" ”

Prime Minister Su Cheng darkened his face, "Call your boss out." ”

The little second wanted to continue to greet him, but when he saw Prime Minister Su followed by a group of fierce-looking people, he looked like he was here to find fault. He knew that the visitor was not good, so he nodded his head and bowed, and immediately ran to the back and called the shopkeeper.

The shopkeeper heard the movement, pretended to be calm and walked out from behind, but when he saw that the person who came was Prime Minister Su Cheng, he breathed a sigh of relief, stepped forward, hugged his fists and said: "I don't know that Prime Minister Su is coming, and the contemptible people are far away," As he spoke, he glanced at the person behind Prime Minister Su and asked, "I don't know what my lord means by this?" ”

Prime Minister Su pursed his lips, glanced at the shopkeeper, and did not reply to his words.

Looking at the interaction between the two, Su Mujin raised her eyebrows, "You know each other?" ”

"No, I don't know, how can a contemptible person climb high to the prime minister, but I have just seen Prime Minister Su from afar. Why are you two here? ”

"A few months ago, the third prince bought some medicinal herbs from you, is it convenient to talk about it?"

"So you're here for this." The shopkeeper smiled, "Yesterday, the third prince came and specially checked the medicinal materials I have here, please rest assured, there is no problem." ”

"Really?" If he says there is no problem, there must be no problem? If there is a problem, at least you have to check it, Su Mujin said: "Even so, I think it is necessary to watch it again." ”

"As it should be." The shopkeeper clapped his hands and sent Xiao Er to get the medicinal materials that he gave to the third prince yesterday.

After a while, the medicine came. Su Mujin took a look, these medicinal materials include rehmannia root, dogwood, wolfberry, dodder seed, yam, deer horn gum, angelica, eucommia charcoal, cinnamon and Sichuan aconite, all of which are used to tonify the kidney, and it seems that there is really no problem.

However, there is a strange thing, these medicinal materials are mixed with the medicinal materials of loquat old leaves, and the old loquat leaves and the medicinal materials of kidney tonic are put together, which seems a little out of place. She frowned, picked up the loquat old leaf, and asked, "This loquat old leaf is used to dissolve phlegm, and the third prince has had wind chill for a few days?" ”

The shopkeeper shook his head, "This medicinal herb was bought by Miss Su, and I don't know if it's wind chill." ”

"Even if I bought the medicine, what can I do?" While the shopkeeper was talking, Su Ruyun walked in from the outside, her face full of disdain, "Su Mujin, let you investigate the poisoning, but you put the cart before the horse, and came to the pharmacy to investigate the situation, if you let the murderer go, can you bear the responsibility?" ”

Damn, how can you meet this woman anywhere, Su Mujin was too lazy to talk nonsense with this woman, she pouted, "Prime Minister Su brought me here, what do you mean by this, aren't you blaming Prime Minister for putting the cart before the horse?" ”

"You, presumptuous!"

Su Ruyun raised her hand and was about to give Su Mujin a slap, however, her slap not only failed, but was also beaten back by Su Mujin's backhand.

With a hot pain on her face, after Su Ruyun was beaten, she looked at Su Mujin in disbelief, and couldn't believe what she did: "You dare to beat me?!" ”

"Father!" Su Ruyun grabbed Prime Minister Su Cheng's arm, pointed at Su Mujin, and said with a face full of grievances: "This woman beat me in front of you, you have to make the decision for me." ”

"Calling the shots?" Su Mujin laughed, "I'm just defending myself, what's wrong?" ”

After saying this, she looked down at the loquat leaves, and asked, "I heard that in the days when the third prince was poisoned, you came to this store to buy loquat leaves?" ”

"What if you buy it?"

"Nothing." Su Mujin said: "Let's go, go see the third prince." ”

She felt that she already knew the cause of the poisoning of the third prince. This shop receives medicinal herbs, and they all look fresh. Loquat leaves are no exception, but as everyone knows, old loquat leaves are not processed and taken with other things, there will be. What she had to determine now was what the three princes had eaten that day.

Coming out of the shop, their group went to see the Three Princes' Mansion. At this time, the third prince was just about to go out, but he was blocked by Su Mujin.

As soon as he saw Su Mujin, the third prince was like seeing a plague god, his brows were furrowed, and he said with a gloomy face: "What are you doing here?" ”

"Of course, I helped the three princes find out who poisoned them, lest the three princes not find the poisoners, so they will talk everywhere."

Su Mujin's words were very straightforward, and she didn't leave any face for the third prince.

The third prince smiled, "If you can find the person who poisoned you, it will naturally be a great thing." ”

"It's a deal."

Entering the mansion, the three princes exchanged the information they found to Su Mujin, Su Mujin never got any favorable news from it, she only found out about the three princes' food, and the green hand is abundant in Yunnan, it is an ordinary mushroom that can be used, and a small part is poisonous.

If this mushroom is combined with old loquat leaves that are too new, there is a high chance that it can cause poisoning if it is not handled properly.

After Su Mujin said this, the third prince instantly fixed his eyes on Su Ruyun, and he clearly remembered that the mushrooms and loquat paste he ate that day were all made by Su Ruyun.

He didn't say too much about her, but it wasn't so bad that she was going to be poisoned, right? Besides, what good would it really do her to poison him?

No matter what she says now, Su Ruyun can't run away. The third prince was furious, and directly slapped Su Ruyun and asked, "Why did you poison me?" ”
