The princess was ordained by Heaven.

Wang Feiyu didn't refute, his brow furrowed with worry for some time: "What I mean is, it seems like someone is up to something."

"It's not just a possibility, it's inevitable."

Xu Zhen's voice came from the other side of the wall.

In order to avoid direct contact with outsiders, he has been discussing matters with Pang Yunyi and the others in this manner for the past few days.

The wall was hastily built to block the plague; it's fairly sturdy, but it doesn't block out much sound.

"There are two places: one is the water source, and the other is the horse's fodder."

"Horses? We don't eat or live with horses, so it's normal for them to be like this!" Pang Yunyi asked, puzzled.

"As the weather gets warmer, some soldiers who love horses will cut some fresh hay to feed them. I have carefully questioned the soldiers who have contracted the plague, and it turns out that nearly half of them are cavalrymen."

This number basically eliminates the possibility of coincidence.

Wang Feiyu asked solemnly, "How did they do it?"

He spoke urgently.

It's important to know that the people most involved in this incident were his subordinates.

He was so anxious that he developed several blisters on the corners of his mouth.

"I'm afraid we'll only know after we investigate."

Xu Zhen also knew that this guess was somewhat inexplicable.

But there are many methods in this world that are unknown to most people. Just because they haven't seen them doesn't mean they aren't possible.

Wang Feiyu looked at Pang Yunyi.

Knowing he was anxious, Pang Yunyi didn't make things difficult for him: "Go ahead. You'll handle the cavalry, and I'll arrange for someone else to investigate the water source."

Wang Feiyu had something on his mind and left in a hurry.

Pang Yunyi, however, was not in a hurry to leave.

"Xu Zhen, tell me honestly, you're doing well now, right?"

Xu Zhen's calm voice came through: "Of course."

"That's good. Take good care of yourself."

After saying that, Pang Yunyi strode away to attend to important matters.

He was naturally unaware that Xu Zhen, who was separated from him by a wall, was trembling slightly in the hand holding the calligraphy brush.

He was not particularly robust to begin with, and now, after days of hard work, he has become emaciated, and even his once radiant face has turned dull.

The brown shirt draped over his thin shoulders seemed to accentuate his frailty.

It's only been a few days.

He coughed lightly, and even though his handwriting was already sloppy and illegible, he did not stop.

A young soldier with milder symptoms volunteered to grind ink for him, but seeing his condition, he hesitated to speak several times because he didn't want to bother him.

Xu Zhen noticed his unusual behavior: "Just say what you have to say, why beat around the bush?"

"Mr. Xu, you should take a rest..."

Xu Zhen has been working non-stop lately. When he finally has some free time, he doesn't rest but instead personally takes care of the patients.

Even a person made of iron can't withstand this kind of torment.

He now carries the hopes of many patients and must persuade Mr. Xu to rest.

"Don't worry, I just have a minor cold."

"But the army doctor also said that people with poor health are more susceptible to the disease... Pshaw, I'm just talking nonsense, God help me, God help me!"

Xu Zhen didn't answer, because he had already refocused on what he was doing.

What is he doing?

He was writing poems.

This was the most fun he could have after finishing his business.

As the prosperous era of the Great Yong Dynasty began to unfold, there was always someone who would sing its praises.

He was confident in his talent and naturally wanted to be an embellishment to this prosperous era.

Of course, what if his writing doesn't stand the test of time...

Well, let's just pretend he didn't do or say anything.

Meanwhile, outside the checkpoint leading up the mountain, several people were blocked from the road.

"Who is coming?"

The soldiers on duty, holding long spears, called out loudly from a distance.

"The benevolent doctor Yuan Qian".

“Tingzhou Qi You”.

"Fuzhou Apricot".

……

Hearing different place names and different accents, the soldiers on duty were somewhat puzzled.

Why have you come?

"It's dangerous here. You're not allowed to go into the mountains. You should leave."

Yuan Qian patted his medicine box: "We are doctors, here to fight the epidemic."

When the soldiers heard the purpose of their visit, their faces lit up with joy.

After verifying their identities, a young officer, his face flushed with excitement, exclaimed, "The notice had just been distributed, and we thought it hadn't spread to other states yet. We didn't expect you to arrive so promptly."

Seeing the tears in his eyes, Doctor Yuan comforted him, "I happened to be in Dongzhou with my students and old friends, and I rushed over as soon as I heard the news."

It's a coincidence, and it's not a coincidence.

After General He returned to Beijing, Yuan Qian retired after achieving his goals.

Knowing that the battle at the front was critical, he had no intention of going any further south.

Just then, he received a letter from Qi You, inviting him to Dongzhou to treat a patient with a rare disease. So, he brought his students to Dongzhou.

Who knew that, by such a coincidence, Dongzhou needed a doctor.

"Perhaps it is the will of Heaven that the Great Yong Dynasty has endured and prospered. It is because Heaven has not forsaken the Great Yong. It is also because Her Highness the Crown Princess could not bear to see the people suffer that so many benevolent doctors travel around the country."

The young general bowed gratefully in the direction of the capital, suppressing his anxiety, and said, "You all must be tired from your journey, why don't you rest first..."

"Who knows the best about this situation here? Take me to see him."

Qi Youdao said, "The rest of us should go check on the patient first."

The young officer paused for a moment, then said, "I understand... It's our General and Mr. Xu. The General is away on business, and Mr. Xu is with the patients."

"Xu Zhen? Then let's go straight there."

Before the young man could say more, the doctors kept urging him to hurry up.

Infected by their anxiety, he walked faster and faster.

He was worried that they wouldn't be able to keep up, but to his surprise, they were all incredibly agile.

No wonder he's a doctor, he's in such good health.

The doctors walked straight into the cordoned-off area, and Pang Yunyi, who had rushed over after receiving the news, didn't even see their backs.

He angrily flicked the young man who had led the way on the forehead: "Are you an idiot?!"

He was so angry he almost jumped up, but the young officer didn't dare to argue and just listened to the reprimand.

"They told you to lead the way, so you just did it. They've come all this way, and you haven't even given them a hot meal or a bowl of water! You're so stupid!"

The young man asked blankly, "Then what should we do?"

"What should we do? Mr. Xu will handle it. Just go about your business. And be more perceptive in the future!"

Pang Yunyi lectured for a while, then left grumbling.

Meanwhile, Xu Zhen had already met formally with Yuan Qian and the others.

Xu Zhen straightened his somewhat disheveled clothes: "Please excuse my poor appearance."

I'm so busy every day that I don't have time to take care of my appearance.

“Mr. Xu, please don’t take it to heart,” Yuan Qian quickly got to the point to avoid embarrassing him. “Please tell me in detail the cause and effect of the soldiers’ illness.”

Xu Zhen was already very familiar with the matter, and briefly recounted the events.

Yuan Qian praised, "You did a great job."

It couldn't be better.

In just a few days, Xu Zhen redefined the layout of the sealed-off area, placing the latrines in a separate location a little further away.

Everyone's clothes and everyday utensils had to be boiled at high temperatures, and the ground was covered with powder from plant ash and lime...

Xu Zhen not only encouraged patients spiritually, but also did a lot of practical things.
