I went through the medical books at home and the codex you gave me, but I couldn't find the answer. ”

"What is it that is causing you so much trouble?" Hearing her say this, Dr. Zhang couldn't help frowning.

"Master, I don't know if you've heard of it, our old yellow dog was poisoned." Song Qingyi said softly.

As soon as she said this, Dr. Zhang's eyes narrowed, and he immediately understood something.

However, he didn't speak, and only let Song Qingyi continue.

And Song Qingyi pursed her lips slightly, and a sneering arc hooked up from the corner of her mouth: "That day, because Er Yu was pestering me, I couldn't get out, so I said casually, let the new maid Hongya go and pour the leftovers to feed the dog, after the old yellow dog ate it, it died on the spot, it foamed at the mouth, stiffened, and it was poisoned at a glance...... Later, Xiaowan and I went to the mountains to dig up its body, and after dissecting it, I found the toxin in it. ”

"But this toxin is incomprehensible to me." Song Qingyi told the whole thing at that time.

"Oh? How you can't understand, talk about it. Dr. Zhang frowned.

"I don't understand what the toxin is made of."

"This is normal, if there is no specific method, but with a toxin, it is really impossible to see the ingredients in it. What kind of toxin was that, did you write it down at the time? ”

"Got it." Song Qingyi took out the toxins she had recorded.

Dr. Zhang took it, twisted his eyebrows and looked at it for a moment, and then said: "Why is this toxin so similar to ......?"

"Like what?"

"Puffer fish poison, but more intense than puffer fish poison."

"Is that so...... Then Master, if you want to configure an antidote, what should you do? There is this kind of poison hidden in the Su family, I really don't feel at ease. ”

"This alone is difficult to configure. However, if you really want to try, you can first try to configure the antidote to puffer fish poison, this puffer fish and Heding red are both highly toxic, it is best to be able to induce vomiting first, if you can spit out some of the poison, maybe it will reduce some of the toxicity in the body. However, this kind of poison is even more powerful than puffer fish poison, even if the antidote is configured, I am afraid that there is still residual toxicity in the body! Dr. Zhang's face was also very serious.

"Residual toxic ......" Song Qingyi seemed to have something flashing in his mind, but he couldn't catch it for a while.

She thought for a moment and nodded, "Okay, Master, I'll find a few more medical books, it's not early today, I have to go back, I'll come back when these books are finished." ”

"Why don't you stay and have dinner and then go back?" Dr. Zhang retained.

"Still no, after this matter is over, I will accompany Master and Master to have a good meal." Song Qingyi's smile had a hint of melancholy.

"Well, since that's the case, then Master hopes that you will be able to configure the antidote as soon as possible, and Master will try it here."

After the master and apprentice finished speaking, Song Qingyi took several medical books in front of the bookshelf in a disorderly manner.

Her heart was in a mess, and she didn't notice what books she was holding, and then she said goodbye to Old Tang Po and went home.

However, before arriving home, she took advantage of the corner of the road where there was no one and hid those medical books in the space, so as not to be seen by Liu Susu and Hongya when she went back, which would make the two of them suspicious.

When I returned to Su's house, it was time to eat.

Su Yanwen and Er Yu were already sitting at the dinner table, and the other people were still busy in the kitchen.

As soon as he saw Song Qingyi returning, Er Yu quickly stood up and ran over, grabbed her hand, and Song Qingyi touched his head: "Is it time to eat?" Have you washed your hands? I'm going to fetch a basin of water, can you wash your hands? ”

"Ahh Er Yu nodded obediently, but he still had to follow her to fetch water.

The two of them are going out.

However, Su Wanwen called out to her: "You went to Dr. Zhang's house today, why did you go all day?" ”

"Oh, I have something to do, I've been waiting there for the master to go back, he went out early this morning, and he didn't come back until just now, I don't have to go up the mountain today, I'm idle at home and bored, so I accompanied the master to talk for a day." Song Qingyi was reluctant to say anything about the poison, so he answered perfunctorily, and took Er Yu's hand and walked out.

Song Qingyi washed Er Yu's hands by the well, and then brought another basin of clean water into the house, while Er Yu helped her hold the burlap cloth to wipe her hands.

Su Yanwen washed his hands and wiped his hands again.

Song Qingyi was about to go out with a basin of water, but he grabbed her wrist, leaned in front of her, and whispered: "Come to my room before going to bed tonight, I have something important to talk to you about, it is about the news that Tang He sent back from Mengcheng." ”

As soon as he heard him say about Tang He, Song Qingyi knew that he couldn't refuse, so he had to nod: "Okay." ”

As soon as he finished speaking, Lai shouted to eat.

She hurriedly went out with a basin to pour water, and then went to the kitchen to help serve food.

At the dinner table, Lai's had to ask why she went to Dr. Zhang's house today, Song Qingyi didn't want to say more, so she said that she went to chat with the old Tang Po.

After eating, Dr. Zhang came to the door and treated Su Yanwen.

This time, he directly called Song Qingyi to him and asked her to follow, which caused Liu Susu's dissatisfaction, because he had clearly said that Song Qingyi could no longer be allowed to participate in the treatment, but Dr. Zhang didn't care about her at all, and only called the apprentice and went to the East Courtyard.

Liu Susu had no choice but to give up, after all, Lai and Su Xiaowan didn't say anything.

When she arrived at Su Yanwen's room, Dr. Zhang said to her: "After you left today, I have been thinking about the antidote, and then I tried it, but there was no result. ”

This is undoubtedly bad news.

Song Qingyi nodded: "Okay, I know Master, don't worry." ”

She had a loss in her heart that she couldn't hide.

On the side, Su Wanwen frowned: "What antidote?" Ayi, do you have something to hide from me? ”

Song Qingyi didn't look over.

Doctor Zhang only knew at this time that she didn't tell Su Yanwen, so she had to explain: "It's about the old yellow dog in your family......

"Ayi, why don't you tell me about this?" Su gradually got a little angry.

"What's the use of telling you? You don't know how to use medicine, so if one more person knows, wouldn't it be just a matter of worrying about it? Song Qingyi retorted in a low voice.

"Then have you ever thought that if you don't know, you will be defenseless?"

"What do you need to guard against? Liu Susu likes you so much, how could she be willing to attack you? Song Qingyi couldn't help but say.

And as soon as she said this, she regretted it a little.

The vinegar flavor is too strong, right?
