Hua Yan immediately wrote a letter and ordered someone to send it to Lin'an to Hua Zhuo without delay for a moment.

An hour later, Su Zi came to find Hua Yan and said to her, "Now I found out that three people in Bei'an City have contracted the white blister plague. After the words fell, he said with an ugly face, "These three people entered the city at noon yesterday, and their identities are lazy in the market, from yesterday noon to this time, the three of them went to the market, tea houses, casinos and other places in Bei'an City. ”

Hua Yan's face suddenly became ugly, "Picking a place with a lot of people really has ulterior motives." ”

"Not bad." Su Zi said, "It seems that the person behind it wants to bury us with Bei'an City. ”

"What about these three now?" Hua Yan asked.

Su Zi said, "They have been imprisoned, these three people are extremely evil, they don't know that they are carrying the plague, and under interrogation, they only said that someone gave them a large sum of money and let them come to the most lively place in Bei'an City for two days." ”

Hua Yan said angrily, "Who gave them the money, they must not know?" ”

"Hmm." Su Zi nodded, "The three of them only said that they were masked people in black, and they didn't know their names, so we couldn't find out." ”

Hua Yan stretched out her hand and patted the table, "Treat human life as grass mustard, and animals as well." If one day I find out who is behind it, I will cut it with a thousand cuts. ”

Su Zi said coldly, "The daily market is full of people, the teahouse and the wine shop are also full of people coming in and out, and the gambling house and song shop are also endless. Now it is impossible to find out how many people these three people have come into contact with, and how many people have been infected with the plague, and we can only wait for the symptoms to show before we can know the exact number. ”

Hua Yan said in a deep voice, "There are tens of thousands of people in Bei'an City, and the three of them are plagued by a group, and the plague is estimated to spread soon." ”

Su Zi nodded.

Hua Yan pursed her lips, "But our medicine is not enough, and we lack a taste of medicine." After the words fell, she told Cheng Zixiao that someone had taken away all the coiled ginseng in the pharmacy two months ago.

Su Zi cut his brows and knotted his brows, and said with a gloomy face, "In other words, today's Panlong ginseng is a cup of water?" ”

"That's right." Hua Yan nodded, "Except for the pharmacy under Cheng Zixiao's name, because I took over the closure and rectification, I kept the Panlong ginseng, but it was not enough at all." And since the people behind it planned to let us die, they started to collect the dragon ginseng two months ago, I am afraid that the places in the world that can receive the dragon ginseng have all been collected, even if we try to search around, it will be too late in time. ”

Su Zi asked in a deep voice, "So, we have no way at all?" ”

Hua Yan pursed her lips, "At present, there is no good way except to find Panlong ginseng." ”

Su Ziqi suddenly said, "What if you replace Panlong ginseng with other medicines?" The words fell, and he looked at the sky that had been sitting aside without talking.

The sky was stunned.

Hua Yan's eyes lit up, and she also looked at the sky, "Yes, the prescription was researched by you many years ago, and now your medical skills are even more refined than many years ago, can you re-study and study the prescription and replace it with a medicine instead of Panlong ginseng?" ”

Tian Bu kept reaching out to brush the tiger's whiskers, pondering and saying, "This can be tried." ”

Hua Yan suddenly said, "Now there are those three people, you do a good job of protection, go to see those three people, and just use those three people for you to test." ”

Tian Bu nodded and stood up, "The old man is waiting for your words." The words fell, and asked Su Ziqi, "Where are those three people being held now?" ”

"Green Soul." Su Zi shouted.

"Childe." The green soul appeared.

Su Zi ordered, "Take the divine doctor to take the place where the three people are being held and protect it carefully." ”

"Yes." The green soul responded.

Tian Bu will never delay, and immediately followed the green soul.

After Tian Buzhi left, Hua Yan looked at the large snowflakes outside the window and said, "I hope he can figure out a substitute for Panlong ginseng, otherwise this Bei'an City may really become a dead city like those two cities a hundred years ago." ”

"You should have faith in him, the miracle doctor is not in vain." Su Zi slashed.

Hua Yan nodded and calmed down.

On that day, Tian Bu never came back, and the news came back that one of the three people had died.

In the middle of the night, An Sixteen came back from outside and said to Hua Yan, "Young master, it has been found out that due to the heavy snow, there are not many people going out in Qingpu County, only ten people have come out, three people have come to Bei'an City, and seven people are a family of seven who went to Guiye Town to visit relatives and friends. ”

Hua Yan breathed a sigh of relief, looked out the window and said that the heavy snow had fallen a foot deep, "It seems that I want to thank you for this winter snow." The target of the people behind it is Bei'an City, so it is unlikely that the plague will spread to other places. ”

An Sixteen nodded, and said to Hua Yan again, "As of Bei'an City tonight, another fifty-three people have been found and have been imprisoned. By tomorrow, the number of people will double. ”

Hua Yan pursed her lips, "How many plates of dragon ginseng are there in the pharmacy under Cheng Zixiao's name?" Can the statistics come out? ”

An Sixteen said, "The statistics are out, because Panlong ginseng is mostly produced in the wetlands of the southeast, so the output in Nanchu is not much, even if it is not deliberately bought by someone with a heart two months ago, I am afraid that it will not be able to solve the plague in a city." Cheng Zixiao's pharmacy only collected two boxes of more than ten catties, and most of the ones you ordered to collect earlier were sent to Qingpu County, and now Bei'an City is only one or two catties. ”

Hua Yan pondered for a moment and said, "According to the prescription of the endless heavens, reduce the coiled dragon ginseng by half, and first try to see if you can delay the death of those infected with the plague." ”

An Sixteen bowed, "I'll try it now." The words fell, and he didn't even bother to drink his saliva, and went out again.

Hua Yan stood in front of the window, thinking that she hoped that the heavens would be able to research a medicine that could be used as soon as possible, and now she could only pin all her hopes on him.

Cai Qing brought a plate of snacks, put it on the table, and whispered, "Princess, you didn't have to eat tonight, how can you survive your body and bones like this?" Let's use two pieces of sweets. ”

Hua Yan glanced back at Cai Qing, then looked at the snacks on the table, and shook her head, "I can't eat it." ”

Cai Qing immediately said, "You want to eat as much as you want." The slave doesn't understand the big truth, but I have heard that His Royal Highness the Crown Prince said to Xiao Zhongzi that the more something big happens, the more calm you should be. ”

At the mention of Yun Chi, Hua Yan smiled slightly, turned around and sat down, pinching a piece of pastry, "He's right, the more this time, the more calm I should be." ”

Cai Qing secretly breathed a sigh of relief when she saw Huayan eating, thinking that she had always thought that Xiao Zhongzi was a fool, but now she found that he had a big advantage, that is, what His Royal Highness the Crown Prince said, he always remembered it, and at critical times, it was very official.

Hua Yan used two pieces of pastry, then drank some water, and said to Cai Qing, "You send someone to tell Cheng Zixiao, and ask him to take some of each of the various types of medicine in the pharmacy and send them to Tiannong, lest he can't think about all the medicinal materials in the world for a while." I really couldn't think of a prescription, so he blindly changed the experiment. ”

Cai Qing should be, and went immediately.

After Cai Qing left, Hua Yan rubbed her eyebrows tiredly and glanced at the bed, although her mind was troubled and sleepy, she still went to bed and forced herself to sleep. At this time, her mind must be calm and clear, and she must not be so messy.

Hua Yan slept for two hours, and when she woke up, it was already dawn.

She didn't get up immediately, but lay on the bed against the roof of the shed, thinking about things very clearly.

After a while, she suddenly pushed away the quilt and got out of bed, shouting outside, "Cai Qing." ”

Cai Qing immediately responded, "Crown Princess, are you awake?" With that, he opened the curtain and entered the house.

Hua Yan asked her, "How's it going outside?" ”

Cai Qing immediately said, "According to the latest statistics of the Sixteenth Prince, the number of people infected with the plague has reached two hundred and forty-two people yesterday. Fifteen people had died, and the plague had struck so quickly that it had only taken six hours from the time of the attack to the time of death. According to your instructions, the sixteenth prince reduced the amount of all the dragon ginseng in the city into medicine, and the fifteen people drank less, did not resist, and only delayed for an extra hour. ”

Hua Yan's heart sank and asked, "What about Zi Chop?" ”

Cai Qing immediately said, "Zi beheaded the son did not sleep all night, transferred 20,000 people from the Jingguo army, and half an hour ago, the 20,000 people were divided into more than a dozen teams, and shouted along the four cities of Bei'an City, east, west, north and south, so that everyone is not allowed to leave the house from today onwards, and if there is a violator, behead the public." ”

Hua Yan nodded, "That's right, as long as no one walks around on the street and people don't come into contact with each other, tens of thousands of people in Bei'an City won't be covered by the plague too quickly." ”

Cai Qing nodded, "The son of the son contracted the wind cold again, and the slave and maid boiled the medicine according to the prescription prescribed to him by the divine doctor that day, and he just went to rest after drinking it." ”

"Let him rest!" Hua Yan looked out the window, the snow was no longer falling, but the north wind was blowing fiercely, whistling, blowing up the snow that fell on the ground layer by layer, blowing into snowflakes all over the sky, looking like it was still snowing.

She stood in front of the window and looked at it for a moment, shouting, "The clouds are dark." ”

"Master!" The clouds appeared in response.

Hua Yan commanded in a deep voice, "You take the secret guard to investigate, starting from Qingpu County, and check it for me little by little, I don't believe that the person behind it has no clues about doing such a big thing." ”

The clouds should be dark.
