Yang Qingyan stepped into this small farmhouse courtyard, with ordinary mud walls and thatched roofs. There are three rooms in a horizontal row, two on the left and right.

Under the corner of the courtyard wall, some flowers and plants are planted, which are particularly prominent in this cold winter day compared to the depressed scenery.

Yang Qingyan simply glanced at the flowers and plants, and walked to the family's kitchen.

When I entered the kitchen, I quickly found the water tank.

The water in the tank had not been touched for some days, and a lot of grass and dust from the roof had fallen inside.

She picked up the gourd scoop next to her, scooped a spoonful and put it on the tip of her nose and sniffed it, there was nothing unusual at all.

But she still took out the empty bottle she had brought with her, filled it with a porcelain bottle of water, and put it in her medicine box, before she walked out of the kitchen and left the family's yard.

The soldiers who were waiting outside saw her come out and immediately greeted her.

"Girl, but what have you discovered?"

Yang Qingyan shook his head: "I haven't found anything yet, let's go to the next one." ”

The leader of the soldiers immediately took Yang Qingyan to the next few houses, and after Yang Qingyan took some water, he planned to take it back to his mother-in-law to see if there was a problem.

After all, she can't learn medicine, and she is still lacking in the smell recognition of medicinal materials. There was nothing unusual about her smelling the water, and she didn't know if it was because it had been too long, and all the medicinal properties in it had already been released.

"By the way, I saw that some people's homes are filled with water tanks, and I haven't seen a well in the yard of any house, does this big brother know where their water comes from?"

In the end, Yang Qingyan decided to go to the source of the water to see, perhaps, the problem is really in the water.

"There are three wells in the south of the city, and there is one when you go out and turn left in this alley, girl, please follow me."

Yang Qingyan followed the soldiers through the alley and came to the well. She looked around, the cold winter had put all the plants around her to sleep.

The plane tree not far from the well has also lost its leaves, and it looks particularly desolate.

It's just that there is a touch of green in the open space next to the well. White flowers the size of a mother and child are blooming in the cold wind.

It seems to be adding a touch of vitality to this bleak winter.

This flower is the same as the flowers she saw in the yards of the few houses she went to just now, and Yang Qingyan didn't pay attention to it.

When the leader of the soldiers saw that she was going to fetch water, he immediately stepped forward by himself, threw the bucket into the well, and beat half of the bucket.

Yang Qingyan filled a bottle of water as usual, made and marked it.

"Aren't all the people around here sick?"

Along the way, Yang Qingyan didn't see anyone, and couldn't help frowning and asking like the leader.

"Well, the south of the city is the most severely affected place, followed by the east and west of the city, and the north of the city is the least. Now that the prince has placed them in isolation, there is no one in the south of the city now. ”

Yang Qingyan didn't expect it to be so serious, and he didn't dare to delay any longer, and immediately returned to the "Hanging Pot Hall" with the medicine box.

As soon as he entered the "Hanging Pot Hall", the old man Bai greeted him happily: "Miss Yang, you have worked hard, but what clues have you found?" ”

Yang Qingyan was indeed a little tired, carrying a heavy medicine box on her back, walking more than a dozen streets, and then turning back to the north of the city, she felt that the soles of her feet were about to wear blood blisters.

Besides, it's already afternoon, and I haven't eaten a little yet, so I feel a little exhausted.

Facing the eager eyes of the old man Bai, she didn't have time to answer, but a female voice broke into the ears of the two first: "Miss Yang is a capable person, how can she not gain anything from going out for so long this time?" Doctor Bai, you are also worried in vain, now the life and death of all the people in Los Angeles are all remembered on Miss Yang's master and apprentice, how can you underestimate her? ”

Listening to this, it seems to be complimenting Yang Qingyan. But Yang Qingyan knew the nature of this white lotus, so naturally he would not listen to these words as praise.

But now is not the time to deal with this woman, she has to send the water to her mother-in-law to analyze it as soon as possible.

It's better for the white lotus not to fall into her own hands, and she is not a virgin herself, so she won't care whether this person is a county lord or a princess, just as well!

"Hehe, the county lord is very leisurely, huh? Since I don't care about the love of the emperor and queen, I also want to do something for the people of Los Angeles, so it just so happens that I haven't had time to collect the well water in the north of the city, so I will leave this matter to you, and you must collect a bottle of water from every household in the north of the city for me before it gets dark today.

In addition, the name of each bottle should be written on it, and whether there is poisoning should also be recorded. ”

When the words fell, Yang Qingyan didn't look at the face of Lord Mulian who was about to deform with anger, nodded and smiled at Old Man Bai, and went directly to the backyard to find his mother-in-law.

"County Lord! I think this woman did it on purpose! You are a golden branch and jade leaf, this body is so golden, how can you do such a thing? There are so many doctors here, and that woman doesn't send them, but they assign you to go! I look at the woman and deliberately make the county lord! ”

Xiao Qian, who is beside the county lord of Mulian, is indignant, she has always been by the side of her own county lord, both of them are used to the flattery and pursuit of the nobles of the imperial city, but they didn't expect to come to this Los Angeles, they were squeezed by a hillbilly and wore small shoes, her county lord can stand it, and she, who is a maid, can't get rid of this evil breath!

Of course, the county lord of Mulian couldn't bear it, but suddenly her eyes rolled, and she immediately grabbed her maid Xiaoqian's hand: "Xiaoqian, don't talk nonsense, this is what the prince ordered, and we have to listen to Miss Yang's arrangement." Let's go, we have to go quickly, otherwise we won't be able to complete the task arranged by Miss Yang. ”

Xiaoqian is not convinced! I still wanted to argue a few words, but the county lord of Mulian hurriedly glanced at her! She closed her mouth instantly.

Yang Qingyan, who left, had an unusually strong sense of hearing.

took in the singing and harmony of the master and servant, but she didn't bother to pay attention to the white lotus at all, hooked the corners of her mouth mockingly, and strode towards the backyard.

"Master, I'm back."

Pushing open the door, Yang Qingyan hurriedly took down the heavy medicine box from his body and shouted happily. ”

At this time, the mother-in-law was concocting something on a table, and when she heard Yang Qingyan's voice, she didn't look back, and continued what she was doing.

As soon as Yang Qingyan put the medicine box on the table next door, she came to her mother-in-law's side, looking at the bottles and cans on the table, she couldn't help but be full of curiosity.

"Just in time to come back, the master is now using several rare poisonous juices to try to fuse with the poisonous blood of these people.

You can just take a look at how the teacher does it. ”

"Yes, Master!"

Yang Qingyan immediately looked like a studious baby, standing obediently on the opposite side of the table, watching how his mother-in-law mixed the poisonous juice.

"The bottle in my hand contains Lan Ji, this poison is generally grown in the Western Regions, but it is very rare, and this bottle in the master's hand is also collected for most of his life. Its toxicity is very domineering, one drop is enough to poison tens of thousands of people. ”

Hearing her mother-in-law's words, Yang Qingyan suddenly felt a sense of admiration for the "Lan Ji" in the bottle!

"It's really domineering! If two countries are fighting, with a few drops, you can easily defeat the enemy army without a fight! Awesome! ”

The first thing that came to Yang Qingyan's mind was this idea! Who knew that as soon as her words came out, her mother-in-law's eyes, which had always been cold and indifferent, shot straight at her!

looked at her mother-in-law, and almost didn't scare Yang Qingyan so much that she slapped her chest.

"Remember, although most of what you teach your teacher is poisonous, you are not allowed to take the initiative to harm people's lives."

Yang Qingyan was a casual joke, but she didn't think it would make her mother-in-law have such a big reaction.

For the soul of a modern traverser, she is naturally a person who values human life very seriously. Taking the initiative to harm people's lives, she never dreamed of it.

Under the warning of her mother-in-law, she nodded again and again: "Naturally! Master's rest assured is that I am the next joke, Master doesn't have to take it seriously. ”

"Well, remember to be cautious in your words and deeds in the future, and you can't say some things nonsense, if you are heard by someone with a heart and cause trouble, it will be troublesome."

The mother-in-law once again taught that Yang Qingyan naturally only had to be taught.

"Okay Master, I remember!"

Then, the mother-in-law took out several rare poisons, and told Yang Qingyan about their awesomeness and the reaction of people after using them.

Yang Qingyan's memory is also super good now, and she can remember almost all the poisons she has seen today in her mind, some of which are too complicated, and she asked a few times before she remembered.

Immediately afterwards, the mother-in-law used the poison to drip into the bowls containing the poisonous blood, and waited for the changes in the bowls.

Unfortunately, none of the ten poisons that my mother-in-law took out were fused with those poisonous blood. This means that they have not yet been able to decompose what kind of poison is in this poisonous blood. Then you can't find a way to detoxify.

Seeing her mother-in-law's increasingly frowning brows, Yang Qingyan knew that the poison this time was really powerful!

Even the mother-in-law, who has always been a poisoner, is embarrassed, and it's really a headache!

"Master, since you can't find it, why don't you see if there's anything wrong with the water I brought back?"

As he spoke, Yang Qingyan opened the medicine box, took out the water from the three directions in the city that he went out today, and put it on the desk.

"Go get me some more clean bowls."

The mother-in-law instructed, and Yang Qingyan immediately followed. After a while, he brought a stack of bowls.

She poured all the water from the bottles into the empty bowls, and the mother-in-law took out a porcelain bottle and poured the pale green medicinal juice from the porcelain bottle into the well water at one time.

"This is a medicinal juice that has been tested to be non-toxic, in my medical book for you, I have copied a recipe in it, you go back and look at it yourself."

The mother-in-law didn't introduce the effects of this potion much, but simply said it.

Yang Qingyan immediately put away his curiosity, and looked intently at the well water in those bowls, what changes had occurred after encountering this medicinal juice.
