It took more than two months, and Liu Jin walked around, hungry and cold, but he seemed to have already gained experience. He went through countless hardships along the official road and finally arrived in the capital.

Now that he saw His Royal Highness the Crown Prince, he was almost broken and was about to kneel down and came over.

Liu Jin cried loudly, "I have been having nightmares these days, dreaming of many things, afraid that I will never see Your Highness again...I..."

"Let's wait!" Fang Jifan yelled.

Liu Jin paused.

Fang Jifan said: "Are you having a nightmare? Are you still tired and have a little drowsy?"

"Yes, I...I..."

Fang Jifan shouted: "Did you come from Beitongzhou to the capital?"

Liu Jin was stunned. He was mixed with emotions at this time. Although he felt that Fang Jifan’s problem was a little strange,... Liu Jin still said: "Yes. Didn’t we all come to Beijing from Beitongzhou?"

Fang Jifan breathed a sigh of relief.

Beitongzhou... having nightmares, fatigue, drowsiness...

Isn’t this the early symptoms of smallpox?

At least, there is a high chance.

Fang Jifan shouted, "Don't come over, Your Highness, let's retreat, Zhang Yong, hurry up and go to Xishan, let the medical school come, and tell Su Yue to have some protection!"

When Zhang Yong saw Liu Jinlai, he felt ashamed and could not breathe. When he heard Fang Jifan's order, he did not dare to neglect and quickly headed to the west.

Zhu Houzhao couldn't help but say, "What's wrong, what's wrong..."

Fang Jifan pulled Zhu Houzhao far away, then entered the East Palace, ordered people to set up a ladder, poked their heads out from behind the high wall, Fang Jifan shouted: "Liu Jin, stand, don't move."

Liu Jin was alone outside the East Palace, looking around and looking around. Seeing that the gate of the East Palace was closed, he was a little confused. He looked around and looking around: "What, what's wrong?"

"It's okay, it's okay, don't be nervous and don't be suspicious." Fang Jifan shouted hysterically: "It's okay soon, don't run around. It's here. Your Highness the Crown Prince will give you a surprise, don't be afraid!"

I have to calm Liu Jin down like this. This guy is a source of pollution. He can't let him run away and harm others, but no one has the courage to catch him.

Liu Jin was not stupid. He felt something was wrong more and more, so he crawled on the ground, feeling so distressed that he couldn't breathe: "Your Highness, Your Highness, what's wrong..."

Zhu Houzhao probably understood what it meant, so she also poked her head out: "Parent Liu, be good, listen to Lao Fang, Lao Fang will not harm you, it will be fine in a while."

After hearing the prince's words, Liu Jin felt relieved, but he still crawled on the ground and said crying: "I... It's so miserable. I'm here to attack Poyang Lake, I'm hungry..."

Zhu Houzhao and Fang Jifan got down the ladder. Fang Jifan was panting and ordered the eunuchs and guards who arrived: "Everyone is careful, don't go out, ask people to go through the side door, block the nearby streets and alleys, and no one is allowed to come. Prepare a few archers, and are on both sides, so as to prevent Liu Jin from running away and harming people. If he is crazy, he will jump over the wall and shoot him back."

Zhu Houzhao felt a little reluctant: "Lao Fang, Liu Baoban is not such a person."

"Your Highness." Fang Jifan said sadly: "Eunuch Liu is my loyal and loyal in the Ming Dynasty. Your Majesty has issued a special order to praise him and built a stone yard for him. For such a loyal and kindness, Fang Jifan is a conscientious person, how can he bear to harm him? But now is an extraordinary time. If Eunuch Liu really gets smallpox, if he is letting him escape, it will harm the entire capital. But if he can hold him and study it carefully, perhaps he can cure countless people. It is of great importance, so he has to aggrieved him."

Zhu Houzhao didn't say anything, moved the ladder and climbed up the high wall.

But Liu Jin sat cross-legged outside, opened the bag, took out half a cold rice dumpling from it, bulged his cheeks, and started to eat it.

Obviously, Liu Jin was open-minded. Liu Jin had never seen the world, and he had never experienced the danger. Now that people have arrived in the capital, the East Palace is right in front of him, happiness is waving to him. No matter how hard or difficult it is, it is impossible to compare with the wandering along the way. When you are hungry, fill your stomach first.

He held the rice dumpling in his palm and ate it very seriously. He ate it in small bites. He needed to chew it carefully and swallow it slowly before he could swallow it reluctantly.

Zhu Houzhao breathed a sigh of relief and went down the high wall.

Waited for more than an hour.

After Liu Jin finished eating, although he didn't understand anything, he felt that something bad might happen, but it didn't matter. He had experienced a lot of such things.

It was noon, and the sun was shining brightly and the sun was very warm. When he was full, he looked indifferent and lay on the ground, with his hands on his head, his feet up, and basking in the sun.

Be calm and calm, not happy or worrying.

Finally, Su Yue came with more than a dozen medical students.

They prepared a large cart, which was covered tightly and completely sealed.

Not only that, everyone wore masks and covered their heads tightly with leather hoods. There was only one glass eye mask that could see their eyes.

Wearing a leather hood on his hand, a group of people rushed forward without saying a word, Liu Jin shouted: "What are you going to do?"

Then, someone pressed him tightly to the ground and began to tie him up. Someone specially put a mask on him, covering a sack, then twisted the hole in the sack and tied it to death with a hemp rope. Then, everyone carried Liu Jin in the sack and threw it into the car directly. The car cover was dead. Someone took a nail and used a hammer to completely seal the car door.

Suddenly, the world became quiet.

The carriage quickly headed towards Xishan Medical College.

Fang Jifan and Zhu Houzhao immediately went to the West Mountain.

When they arrived, Liu Jin had been tied to the operating table in the silkworm room. Several medical students tinkered in his body for a while, and finally someone came out and breathed out: "It's certain that he was infected with smallpox, but... he hasn't had acne yet."

Fang Jifan nodded and said, "Great, I'll go in and get his saliva, and prepare more cows for me, the more the better."

Fang Jifan began to wear protection. In case of precaution, his protection was very tight and he would never allow any exposure.

Zhu Houzhao couldn't help but say, "I will go in and take a look."

Fang Jifan shook his head: "Your Highness, you only need to be treated when you treat your illness, so there is no need now."

As he said that, Fang Jifan entered the silkworm room. In the silkworm room, Liu Jin tied his limbs and peeled his whole body clean. His head became more and more drowsy, and he said cryingly: "I want to see Your Highness, I want to see Your Highness, I want to see Your Highness, I am so cold and hot, I... hungry... I'm hungry..."

Fang Jifan started to take the virus on him and said, "It won't matter. It will be cured soon. You are just sick and the fever will fade. Your Highness has prepared a lot of delicious food for you, so you won't be hungry later."

Liu Jin cried loudly: "Why, why... why is this happening!"

Fang Jifan looked at Liu Jin crying in his goggles, and Fang Jifan took a deep breath: "Be strong."

After putting the received saliva and body fluid into a glass bottle, Fang Jifan said: "You should recuperate here. This time, you will make great contributions."

I said in my heart that it depends on yourself whether you can handle it.

Those who can survive under the smallpox are all kings.

…………

Next, it became much easier, and Fang Jifan needed to let the cows start to get into smallpox.

Because the body structures of cows and humans are different, smallpox is very fatal to humans, but for cows, it is just a slight infection. Even if you transmit this cowpox to humans, it will only cause slight discomfort.

But because of this slight discomfort, people are infected with smallpox at the same time.

You know, smallpox will become immune once it is infected.

Therefore, the principle of vowel is that since you are infected once, you will no longer be afraid of smallpox virus, then you might as well use vowel to infect people. After being infected with vowel and having mild discomfort, you will have antibodies against smallpox from then on, and since then, you will no longer be afraid of smallpox.

The cow was full of treasures. Looking at the heifer locked in the circle, Fang Jifan and Zhu Houzhao are now staying in the cow's pen every day, observing whether any cows have been infected with smallpox.

On the fourth day, sure enough, several cows began to show symptoms.

Zhu Houzhao jumped three feet high excitedly: "Hurry, come and see."

After Fang Jifan confirmed that it was smallpox, he was extremely excited: "Hurry up, take acne, get acne."

These cows are still locked together, just like onychomycosis. One infected two people and the two spread to the whole family. These hundreds or thousands of cows are enough to extract a large amount of cowpox.

Then, this "magic medicine" was released.

Fang Jifan didn't say anything and started to suck Zhu Hou's acne.

Fang Jifan took the needle and stained it with the liquid from cowpox. Then, he stabbed it into Zhu Houzhao's skin on one side of his arm. Zhu Houzhao couldn't help but grin: "It hurts."

Fang Jifan despised him: "A man of such a big age is still afraid of getting an injection?"

Zhu Houzhao whined and stopped talking.

Then, Fang Jifan began to vaccinate all the superiors and subordinates in Xishan. Fang Jifan himself naturally rushed to plant it and ordered people to go to the princess's mansion to plant all those who should be vaccinated.

Two days later, the vaccination site began to show rashes. Once the rash occurs, it means that the cowpox has been infected. If the rash does not occur, it needs to be re-inoculated. Two or three days later, Fang Jifan and Zhu Houzhao began to produce herpes. However, the process was quite pleasant and there were almost no adverse reactions. Then, the herpes fell off and scabbed, and the smallpox antibody was born.

At this time, since it was fully confirmed that it was valid, Fang Jifan and Zhu Houzhao rushed to the Forbidden City to meet without hesitation.

In fact, at this moment, smallpox patients have begun to appear in the capital, and the entire capital is already facing a great enemy.
