When Yang Yan heard the news, his brows furrowed, he got up and ran to Poria Cocos's room, pushed Poria Cocos' room open, and saw that Poria was still asleep on the bed, so he quickly woke up Poria Cocos.

"What's the matter, I haven't slept enough?" said Poria, squinting her eyes.

"Poria cocos, Ai Yiming is also sick, this disease may not be so simple," Yang Yan said anxiously.

Poria rubbed her eyes, yawned, and then opened her eyes and said, "Let's go, go see what happened to Ai Yiming?"

When the two arrived at Ai Yiming's room, they saw Ai Yiming's face crimson, sweating a lot on his forehead, but he was covered with a lot of quilts, his body was still shaking, and the next person was cleaning the vomit next to him.

Poria walked to the side of the bed, pressed on Ai Yiming's inch, and then looked at Ai Yiming's face, eyes, and listened to Ai Yiming's breathing.

At this time, the princess, Long Lan and Long Yu also entered the room, looked at Poria and then looked at it, and the princess asked worriedly, "How is it?"

Poria slowly put down Ai Yiming's hand, got up and looked at the visitor, and said slowly: "The situation is not very good, there is still an incubation period of three to five days for this disease, these three to five days are the same as normal people, and the contagion is extremely high."

When Long Yu heard this, he was about to pull the princess out, but the princess broke free, and said: "You are not afraid, what am I afraid of?

"What should I do?" Yang Yan glanced at Long Yu and the others, and then looked at Poria and asked.

"Give him medicine," Poria said leisurely.

"Come, get out of the ordeal," the princess commanded.

"Your Royal Highness, which medicine do you take?" asked the maid on one side.

"The princess," said the princess without hesitation.

The maid hurriedly left, and soon came in with a bowl of decoction, Poria smelled it, frowned and asked, "Is there ginseng here?"

"This is the medicine prescribed by the Tai Hospital," said the princess.

"If you give him this, you will go to the ground for three days, eat normally for four days, recur in five days, lose a lot of water in your body for six days, and die violently on the seventh day," Poria cocos said slowly after seeing this medicine.

The maid who said this didn't know what to do, and looked at the princess on the side.

"How do you say to cure it?" Princess Sword Poria knew what medicine was in it when she heard it, which showed that Poria Cocos was indeed a high level of medical skills, so she thought about it and asked.

"What about my prescription, although it is a little less effective, three times a day, it will be cured in less than ten days. Of course, you can drink it if you are not sick, after all, this disease has an incubation period, and it can be prevented if you are not sick."

"Put that medicine down and go and decoct the prescription prescribed by Dr. Poria Cocos," said the princess.

The maid stood there embarrassed, looked at the princess and said, "Your Highness, there is no medicine prescribed by Dr. Poria cocos."

The princess looked at Long Yu and said anxiously: "Hurry up and urge, so that they must send the medicine here within three days."

Long Yu said yes and left the room, but Yang Yan quietly asked in Poria's ear: "Is Bigu Dan useful?"

Poria nodded and quietly returned: "Just had a seizure, you can give him one, as long as the fever is reduced."

Yang Yan nodded, thinking that when there was no one, he would come and give Ai Yiming Bigu Dan again. Suddenly, the soldier who summoned the message shouted loudly outside the house: "Newspaper, there is a large group of people outside the city pulling medicinal herbs, and they said that they have come to discuss business with the princess."

"Well, do they say who it is?" asked the princess, with some surprise.

"No, I just said, let Her Royal Highness the princess talk outside the city"

The princess looked left and right, and Long Yu, who came back, said, "Let's go, since someone has brought medicine, let's go and see who it is."

Saying that, Long Yu, Long Lan and the princess walked out of the room, out of the Taishou Mansion, and rode their horses all the way out of the city.

Yang Yan opened the maid, secretly fed Ai Yiming a Bigu Pill, and followed Poria to the city to check on the patient's condition, for what kind of medicine, they were not interested in this.

Soon the princess and her party came to the outside of the city, and saw a convoy like a long dragon, filled with sacks and exuding the fragrance of medicine.

A bright and luxurious carriage was at the front, and a coachman saw someone coming, and whispered something to the back, and then a strange man's voice came from the car.

"Her Royal Highness the Princess, I brought so much medicine this time and came to the rescue, I don't know what price Her Royal Highness the Princess can offer?"

The princess was puzzled at first, but when she heard the voice, she stretched her brows and asked with a smile, "How much do you want?"

"It cost 100,000 taels to purchase this batch of medicines, plus the fatigue and freight along the road, how to say that it will cost 150,000 taels, I don't know if Her Royal Highness the princess can accept it."

"Hey, hey, you want more than 200,000 yuan, earn more" Another voice sounded in the carriage.

"You'd better come out quickly, or I'll be rude," the princess threatened.

There was a sudden silence in the carriage, and after a while, the curtain door opened, and a figure was pushed out, "Ouch, why are you pushing me", the man tidied up his clothes, then looked at the princess, and said with a smile on his face.

"I heard that the fourth princess is the first beauty in the cloud country, and today I see that it really deserves its name"

"Ye Ming, why are you here?" Long Yu asked in surprise as he looked at him.

"Brother Long, don't come unharmed, I've been kidnapped" Ye Ming pointed to the carriage and said.

"Stinky boy, if you don't come out again, I'm going to go in," said the princess menacingly, looking at the carriage.

"Sister Ling knows who is inside?" Long Lan asked curiously.

"You'll find out for yourself when you go in and see," said the princess, squinting.

"Okay," Long Lan said as she headed to the carriage, looking curious.

"Don't don't, I'll come out, I'll come out" The voice in the carriage immediately went to normal, and a man wearing a purple brocade robe with a treasure jade around his waist walked down.

"Is that you?" Long Lan was very happy when she saw Ouyang Quan who got out of the carriage, and immediately chased after him.

"Brother Long, let your sister stay away from me" Ouyang Quan avoided Long Lan while asking Long Yu for help.

"I've seen King Qi" Long Yu bowed and gave Ouyang Quan a helpless look.

"Xiaolan, don't make trouble" The princess immediately stopped Long Lan, who was chasing Ouyang Quan. Long Lan pouted and came back obediently, and the princess asked, "What are you doing here?"

Ouyang Quan said with a straight face: "To do business, my medicine is shipped from the north, and the quality is absolutely guaranteed."

"How much do you want?"

"Well, 150,000"

"What's the matter? The business of the mountain villa is not good, and it has changed to the medicinal herb business?" asked the princess angrily.

Ouyang Quan smiled embarrassedly, and then said: "I have no money, I heard that there is a plague here, and a large number of medicinal materials will definitely be needed, so I will bring the medicinal materials here and make some money."

"Tens of thousands of patients, how long can you last these medicines?"

"My medicine is specially bought according to the prescription you sent out, which is enough for you to eat for half a month."

"Which prescription?" The princess remembered what Poria said, the prescription of the Tai Hospital has drawbacks, and if the medicine they sent is the one from the Tai Hospital, I am afraid it will be in vain.

"The cheapest one, the plague, the prescription has a hundred years of ginseng, what do you think, I can't afford the medicine of that prescription" Ouyang Quan said helplessly.

The princess was relieved, took out two silver tickets and handed them to Ouyang Quan, and said, "Here you go, I'm going to take the medicine away, and it's urgent in the city."

Ouyang Quan took the silver ticket, with a smile on his face, and said loudly to the team: "Drive in."

The convoy slowly drove into Fancheng, and the group also followed, the princess and her party were fine, but Ouyang Quan and his party were a little uncomfortable, the city was full of patients, the streets and alleys were everywhere, lying there, and the wailing was endless.

Doctors who were busy coming and going everywhere in the city, Ouyang Quan frowned, and asked, "Is it so miserable?" Why didn't you deal with it earlier?"

The princess looked at him and said, "Since you don't want to care, why do you ask about this?"

Ouyang Quan didn't know what to say for a while, so he could only silently watch the miserable state of Fan Cheng now. Soon the convoy arrived at Taishou Mansion and unloaded the medicinal herbs.

To be on the safe side, the princess gave each of them a pair of medicines, and let them drink them before leaving, because Poria had said that this medicine had a preventive effect.

Soon, Fancheng set up a cauldron again and began to distribute the decoction, and the people of the entire Fancheng lined up on time every day to receive the decoction.

Poria looked at it, and there was nothing abnormal, as long as she took the medicine on time, this plague was slowly extinguished with the passage of time in the world.

Yang Yan and the two returned to the Taishou Mansion, only to see that there were already many people sitting in the lobby, and when the two saw Ouyang Quan, Ouyang Quan and Ye Ming also saw the two.

"It's you"

"It's you"

The four of them said at the same time, Ye Ming even came to Poria Cocos's side, and wanted to say something, but heard Poria say "Yang Yan, beat him".

Ye Ming hurriedly retreated, looking at Yang Yan embarrassedly, he knew Yang Yan's ability, if he really fought, even if he didn't die, he would be great.

"Okay, Dr. Poria is also back, the medicine is enough, let's arrange things, now there are not enough people in Fancheng, we all have to help, but we must be careful, don't get sick, you must drink medicine with the people every day" The princess said loudly.

"We're not sick, so we don't have to drink," Ye Ming said.

"This disease is not as simple as it seems, Ai Yiming is also sick, Long Lan has also been sick, and now some doctors are also starting to get sick, and some people in the imperial doctor are also infected, so I have no choice. The medicine prescribed by Dr. Poria also has a preventive effect, so everyone should drink some of it themselves while going out to distribute it," the princess continued.

After assigning the matter, even Ouyang Quan and Ye Ming were arranging it, and all of them began to boil medicine on the street, and for a while, the whole Fancheng was filled with the smell of medicine.

Some of the patients from the surrounding counties also came to Fancheng, receiving free decoctions every day, and gradually never heard of the dead again, and more and more people who recovered from the disease joined the team to treat the sick, and a dead city slowly became vibrant.

The children of the big family in Fancheng, after taking the medicine prescribed by the imperial doctors, sure enough, as Poria said, began to appear in a critical state of shortness of breath on the sixth day, and a group of imperial doctors were helpless and anxious.

Later, the princess invited Poria to take a look, but Poria only prescribed them a medicine, and after eating it, they vomited, and the children of the big family could breathe smoothly, and then Poria asked them to go to the street to get the medicine, which saved these people.

After that, Long Yu's troops sent the follow-up medicine to Fancheng, and for a while, Fancheng became the only place where the plague could survive, and more and more patients from other places came to Fancheng.

Fifteen days later, the plague, which lasted for more than a month, was finally brought under control, no one was infected, and those infected gradually improved, and the prescription of Poria cocos spread to all parts of the Yun Kingdom, because the medicinal materials used were very ordinary, and ordinary people could buy them, and even they could get them together by going up the mountain by themselves.

Therefore, Poria's recipe was said to be a fairy prescription, and the news that Fancheng's divine doctor Poria saved tens of thousands of people also spread. Many people who were not infected with the plague also began to come to Fancheng for medical treatment, wanting to see the demeanor of the miracle doctor, or to ask for some medicine to prolong life and strengthen the body, and Fancheng became lively for a while.

After the plague in Fancheng was eliminated, Poria and his entourage left Fancheng and went to southern Xinjiang with the remaining medicine, because of the epidemic on the border of southern Xinjiang, many soldiers appeared in Fancheng, and the group bought medicine all the way and went to the battlefield in southern Xinjiang with the convoy all the way.

As for those imperial doctors, they were all driven back by the princess, and there was no one left.

"How is the situation over there?" asked the princess in the carriage.

Long Yu rode his horse and returned: "The situation is okay, I have already informed the general to burn those who died, and they are also boiling the pot to fry the medicine, but the medicine is not enough, so we must rush there as soon as possible."

"Is there any news from the girder?"

"The spies came to report, there was also a case on the side of Daliang, what the situation is, I don't know yet"

"Tell them to persevere, and have a good rest when they get to southern Xinjiang"

"Yes," Long Yu agreed, and kept conveying the princess's orders to every carriage behind.

Long Lan and Ai Yiming had a carriage, Ouyang Quan and Ye Ming had a carriage, Yang Yan and Poria cocos had a carriage, the carriage was loaded with medicinal herbs, Poria was sleeping on the medicinal herbs, and Yang Yan also fell asleep.

The convoy traveled all the way south, occasionally stopping to cook and rest, at first everyone felt strange, Yang Yan and Poria didn't eat, and then Ouyang Quan said that the situation was no longer forced.

I picked a lot of fruits along the way, specially prepared for Poria and Yang Yan. In this way, the convoy traveled day and night, and soon reached the southern border of the Cloud Kingdom.

The territory of Yun State is vast, bordering the Great Liang State in the south, and it is harassed by the Great Liang State every year, so the Yun State will garrison heavy troops to defend the territory of the Yun State.

Along the way, the convoy encountered many plague-stricken villages, and the princess ordered pots to be fried along the way, leaving some people to treat those people, and the rest to hurry.

"Princess, we're going to the south of Xinjiang soon, I don't know what's going on over there?" asked Long Yu outside the carriage.

"How many more pills do we have?"

"The news from southern Xinjiang has now been infected by thousands of people, and our medicine is still being distributed along the way, and I am afraid that it will only last for three days in southern Xinjiang," Long Yu said worriedly.

"What did Your Majesty say?"

"The medicinal materials are being collected and transported here, and the three princes are all locked up," Long Yu reported.

"Well, let's go to Tongyang Pass and see the situation," the princess said sadly, and couldn't help but open the curtain and look behind her.

After three days and nights of hurrying, the convoy finally arrived at Tongyang Pass in southern Xinjiang, only to see troops stationed within 100 miles in front of it, tents were particularly conspicuous, and there were many patrol teams outside the camp.

A fast horse came galloping to the convoy and asked, "But the convoy of the four princesses?"

Long Yu replied loudly: "Exactly"

"The last general, Wei Ping, see Her Royal Highness the Princess," Wei Ping immediately dismounted and knelt down on one knee and said.

"Get Up"

Wei Ping got up and said: "General Bai asked the last general to greet Her Royal Highness the princess here, because the war on the front line is urgent, General Bai can't come to greet her, I hope the princess will forgive her sins."

"This is General Bai Qing's Cloud Tiger Legion, what about the Yunfeng Legion?" the princess asked.

"Princess Yu, General Yang is stationed three miles to the west"

"How's it going?"

"Military doctors are helpless, hundreds of people have died, more than a thousand more are infected, and now the patients are isolated so as not to infect others"

"Take us to the place where the patient is isolated"

"Yes" Wei Ping agreed, walking in front and leading the way.
