Everyone was tired from a long journey, so they went back to the palace to rest after a casual stroll.

The next day, after getting up for breakfast, Shen Yuyu handed over the list of medicinal materials written in advance to Irisha.

Since she boasted of Haikou, she naturally had full confidence in developing a medicine to cure the epidemic.

On the way to Daliangcheng, she has already felt the condition of the epidemic patients clearly, acute hepatitis A, severe influenza, mosquito-infected two epidemic diseases, one is called filariasis, parasitic in the lymphatic system of the human body, will cause swollen limba nodes, the other is called malaria, vomiting and diarrhea.

It's not that these diseases can't be treated, but that the conditions are complex and dangerous, and you need to develop drugs that fight four diseases at the same time, so that the medicine can be effective, otherwise curing one other disease can also kill you.

It is precisely because of this that those doctors in the Western Regions are helpless one by one.

Of course, it was not so easy to develop this kind of drug, and in the next few days, Shen Yu spent twelve points of his mind on it.

The honor of the 'God of Medicine' and the treasures are nothing, in fact, this is a huge crisis in the Great Zhou Kingdom.

Ji Xun received a secret letter from Tongzhou Feige, where the number of epidemic patients was increasing exponentially, and it could get out of control at any time.

Of course, these news are also considered state secrets, and they have not been transmitted to the Western Regions at all after the border blockade.

Now Shen Yuyu is in the Daliang Palace to develop the medicine for the treatment of the epidemic with peace of mind, but he borrowed other people's territory and medicinal materials to solve the crisis for his own country.

Fortunately, the medicinal materials in the Western Regions are complete, and with the help of Princess Asha, what do you want, which is very beneficial to the development of medicine for the treatment of the epidemic.

Shen Yu was busy, and Ji Xun was not idle, and drafted several negotiation regulations in advance, so that he could communicate and negotiate with the king of the Western Regions and strive to win the greatest benefits.

On the eighth day, the personnel who went to Aoki Town to inspect the barley returned day and night.

"How?" Yu Chi Lijia stood up from the throne, his eyes were full of expectation, this is a crop that can change the future of the Western Regions, maybe it can make him live in the past.

"Your Majesty, what His Royal Highness the Night King said is true, there is indeed a large area of 'barley' planted on the halfway of that snow-capped mountain, and lo and behold, this big bag has been harvested by us. As he spoke, a few attendants brought a large bag and put it on the main hall.

The King of the Western Regions hurriedly stepped forward, opened the bag and saw that there was a bag of yellow wheat-like crops inside, and he hurriedly took a few grains and chewed them in his mouth, and even the taste was similar.

"Okay~~ Great." Yu Chi Lijia praised again and again, and hurriedly sent someone to invite the Night King to discuss the matter in detail.

This locust plague has caused the cattle and sheep in the Western Regions to almost die, he doesn't know what to do, even if the grass grows next year, where to find the cattle and sheep cubs? Even if you have cows, sheep and cubs, it is not something that can be raised in ten days and half a month.

Unexpectedly, he was cornered, His Royal Highness the Night King solved his urgent need, if he could buy "barley seeds" from the Great Zhou Kingdom, then the food danger of the people in the Western Regions would be completely solved.

Wei Chi Lijia and Ji Xun negotiated for three days in succession, and finally reached an agreement, set five contracts, signed and stamped by both parties.

On the other side, Shen Yuyu had already developed drugs for the treatment of these four epidemics, and Ji Xun was just done, so he accompanied Shen Yuyu out of the city to find patients to test the medicine.

Ten patients, one felt bag for each patient.

After many adjustments to the herbs and dosage, the medicine finally took effect, and the symptoms of 10 patients were reduced day by day, and a young man who was dying was completely cured after taking the medicine for 5 days.

This stunned General Tuo Pohao, who accompanied him to test the medicine, and immediately sent someone to report the good news to the king of the Western Regions.

And Ji Xun also sent the prescription for curing the epidemic back to the Central Plains for the first time.

On the carriage back to Daliang City, Ji Xun took the tired Shen Yuyu into his arms in distress, and his slender five fingers gently caressed her hair.

"Yu Yu has worked hard, if you don't develop a prescription for the treatment of the epidemic, we don't know how much trouble our Great Zhou Kingdom will face."

In just 20 days, the epidemic has spread, at least 100 people in Tongzhou have been infected, and Luozhou City is even more serious, and the poor management of the disease has spread to the city, and countless panicked people have fled in all directions, invisibly spreading the virus to other places.

If no drug is developed to treat the epidemic, the consequences can be imagined.

"Yu Yu's merits are indescribable, you saved our entire Great Zhou Kingdom!" Ji Xun's chin rubbed lightly on the top of her head, and his voice was gentle with gratitude.

How lucky he was to marry a woman casually in order to repay his kindness, it turned out to be like an inexhaustible treasure, bringing him unexpected surprises from time to time.

"When I return to the capital this time, I will ask my father to issue a decree to give Eucalyptus the title of Night Princess, okay?"

Seeing that Shen Yuyu didn't respond for a long time, Ji Xun buried his head and looked, this girl was so tired these days that she had fallen asleep in his arms.

The news that Shen Yuyu had developed a prescription for the treatment of the epidemic quickly spread in Daliang City, and all the doctors in the Western Regions who were waiting here to see Shen Yuyu's jokes were stunned.

"It's amazing, this Central Plains girl is really amazing."

"Isn't it? How old are you? The medical skills are so profound, which is admirable. ”

"Originally, I didn't believe it, but I have a distant cousin who is sick and about to die, and after taking the medicine, he is completely fine, tsk ~ cow!"

"What's your name? I can't despise her like last time when I meet her in the future. ”

"It seems to be called Shen Yuyu, the big proprietor of the world's commercial banks, no, it's time to change his name to Shen Shen." These doctors are also thoroughly admired.

Since the prescription has been developed, it is naturally going to be handed over to the King of the Western Regions.

However, Ji Xun, a master negotiator, exchanged this prescription for countless benefits, and even the marriage between Irisa and General Tuophao was also used by him as an exchange condition.

'Barley" seeds, the prescription for the epidemic, these two things completely won the support of the Western Regions King Yu Chi Lijia to Emperor Qi Heng and the Night King Emperor Fu Ran, and made Yu Chi Lijia surrender.

The night before leaving Daliang City, Yu Chi Lijia personally went out of the palace and gave Shen Yu the title of "God of Medicine" on the square in the city, and accepted the gratitude of all the people.

"Your Highness the Night King, isn't this one your retinue? How could it be~~" Yu Chi Lijia had seen Shen Yuyu once at the dinner on the first day they entered the palace, and when she was given the title at this time, he was also surprised to see that she was a woman.

"This girl is the future night princess of this king." Ji Xun hooked his lips and smiled.

"Oh~~" Yu Chi Lijia suddenly realized, "No wonder His Royal Highness the Night King refuses to make peace with the Western Regions, it turns out that he already has a sweetheart." ’

Ji Xun smiled: "Isn't Princess Asha the same? She went all the way to the Central Plains to prevent the king from agreeing to this family business. '

"That's it, that's all happy, all happy, haha~~'

On the way back to the palace after being sealed, Shen Yuyu said with a strange feeling: "Ah Xun, I was busy developing drugs some time ago, and I didn't think deeply about some words, but now that I think about it, this epidemic with four diseases is really a little strange."
