The 60-year-old man was covered in gray clothes and was tired, but still in good spirits.

He stood with his hands in front of Feng Yuheng, and he was neither humble nor arrogant when facing Xuan Tianming. He had a kind face, but his eyes were filled with endless wisdom.

Feng Yuheng was almost stunned when he saw this person. In a trance, the original owner's memory quickly overlapped with the memory of her soul. The two figures kept colliding and alternating, with the same appearance and the same body, one was wearing an ancient gray robe, the other was wearing a Chinese long gown and jacket, and the other was holding the original owner of childhood, and the other was holding the Chinese medicinal materials of ancient medical books. The other was holding the later generations and talked about traditional Chinese medicine since she was six years old.

The original owner's grandfather, Yao Xian; her own grandfather, Feng Yin.

Feng Yuheng half-kneeled on the ground, a little stunned. The words "Grandpa" were blocked in his throat, and it was neither yelling nor yelling.

Thinking about it again, in fact, when she saw Yao's face, she should have been mentally prepared. Unfortunately, Yao is the original owner's mother, so the one in front of her is also the original owner's grandfather.

There was a burst of disappointment on her face. She held the injection in her hand, stood up from the ground, and looked at the person in front of her and shouted calmly: "Grandpa."

But there was still joy in the eyes, because the original owner's memory was too strong about the part about this grandfather Yao Xian, as if her best memories of childhood were related to Yao Xian. Yao Xian was the man who was called a miracle doctor, and even after she came to this world, she heard people mention it only once. However, there was always a small knot in the original owner's heart, that was, the mother and daughter of the three of them were exiled to the northwest mountain village. The Yao family treated her so well, so why didn't they save her?

?Why didn’t I take her away? Even if I live together in the deserted state, she would be happy.

Feng Yuheng had no complaints about this. After all, when Yao Xian was convicted and demoted and was unable to protect herself, what ability did she have to find them? Even if she found and took her away, the family members would have implicated the mother and daughter if something happened. Although the original owner did not get a good ending in the end, it was just that this account could not be calculated on Yao Xian's head.

Xuan Tianming also stood up and was with Feng Yuheng's side. He stared at the miracle doctor who had not seen for many years. He felt that this man seemed to be much brighter than when he left Beijing. He had not left too many traces on his face for several years. In addition to his whiter hair, Yao Xian was still Yao Xian back then, and even became more energetic than before.

"Your Highness Nine." Yao Xian bowed his fists, "Long time no see."

Xuan Tianming nodded, "Sir, it's just right. The heavy rain has just passed and the epidemic has already occurred. Hengheng was just saying that he is too busy to be busy. Sir, he is a miracle doctor. With you here, I will be at ease."

Yao Xian was not polite to him, so he nodded and looked at Feng Yuheng again, as if he wanted to say something, but in the end he turned his eyes to Song Kang lying on the ground.

"I hate cold and strong heat, and it will soon be hot but not cold, and my body hurts." He said as he bent down, put a handkerchief on his hand to pinch Songkang's mouth, "The coating is white like powder, and the tongue is red." Then he pinched the pulse, "The pulse is uneven and too fast, which is the initial onset of the epidemic." He said to Feng Yuheng: "The entire account is clear and the people are isolated."

Feng Yuheng nodded and pushed Xiangrong: "Hurry up, help me take everyone out, and then tell the soldiers to guard it, no one is allowed to enter and exit."

I knew the matter was urgent, so I quickly went to do it.

Feng Yuheng looked at Xuan Tianming again, and before she could speak, he took the initiative to say, "I'll help you."

Yao Xian answered the conversation, "Your Highness Ninth is better off going out. First of all, you can't help if you stay. Secondly, there may be many people infected with the epidemic outside. Your Highness must be at peace with you."

Xuan Tianming knew that his words were reasonable, so he stopped stubborn. He just carried Song Kang to the camp bed with his own hands, and then said to Feng Yuheng: "You are careful."

Feng Yuheng thought about it, reached out and took out a few masks from the space. "I didn't have time to prepare too much, so you can keep one of this yourself and send some to the people around you." While saying that, he helped Xuan Tianming wear it, "Just wear it like that."

Xuan Tianming nodded, took the mask and walked out of the clinic.

When Feng Yuheng came to his senses again, he saw Yao Xian staring at her hand in a daze. She coughed lightly and called again: "Grandpa."

Yao Xian didn't say anything, but his eyes moved to the needle tube she held in her left hand. After looking for a while, he turned his head to look at some of the instruments and medicines that Feng Yuheng had previously pulled out of the space in the tent, especially when his eyes fell on those Western medicine boxes, his eyes suddenly shot out.

After a while, he said: "The epidemic is divided into many kinds. Every time the bacteria that breeds may be reborn. Even in later generations, methods that can resolve the epidemic cannot be developed. Therefore, it is necessary to extract pathogenic genera from patients and then develop the most targeted vaccine based on the genera."

After saying this, Feng Yuheng felt his mind "buzzing" and he couldn't come back to his senses for a long time.

She stared at the original owner's grandfather in front of her, rolling the words he had just said over and over in her mind, shocked in waves, and her hands holding the needle were trembling.

Yao Xian shook his head and smiled bitterly, "Western medicines are available, what did you bring?"

Without any warning, without any prelude, without any prelude, Feng Yuheng cried with a "wow"! That kind of crying was like a child, with a handful of snot and tears, completely ignoring the image, throwing all the needle in his hand, and the person rushed towards Yao Xian, hugged his neck and howled - "Grandpa!"

Yao Xian took two steps back by her pounce, and finally stabilized her body, and also picked up his little granddaughter. Tears suddenly surged out, and the hands that were stroking her back were trembling.

She called him grandfather, not grandfather. Feng Yuheng didn't realize until this moment that this person was not the original owner's grandfather Yao Xian, but her own grandfather Feng Yin. The grandfather who died a few years ago in her previous life, the grandfather who had taken her to play in the military camp since she was twelve years old. Unexpectedly, the person she thought she would never meet again in this life actually met again in Dashun Dynasty.

Unfortunately, there is no more time to reminisce about the past. Yao Xian resisted the urge to ask her how she died in her previous life, but patted her on the back and said, "It's important to save people, we will say those words later."

Feng Yuheng was not a very affectionate person either. He nodded and let go. Yao Xian still raised his sleeve and wiped her tears, then held her face in both hands and rubbed it three times. She suddenly remembered that when she was a child, she was like this. Every time she slapped her face several times a day.

The tears that she finally held back came out again. She tried to control her, deliberately changing the topic and said: "I'll take a blood sample. Grandpa is a bacteria expert. I'll leave it to grandpa for the development of the vaccine."

Yao Xian nodded, "Okay."

Then she took the mask and gloves that Feng Yuheng handed it to her, and helped her successfully extract the blood sample from the three test tubes.

Feng Yuheng held the three tubes of blood, thought for a while, and simply said, "Grandpa, I'll take you to a place." As soon as he finished speaking, he immediately grabbed Yao Xian's hand and stroked his right hand to his wrist. Yao Xian felt his eyes blurred, and then it seemed like time and space changed again. In the blink of an eye, the lady actually stood in the pharmacy of later generations.

He was so familiar with Feng Yuheng's pharmacy. This pharmacy was originally opened by him when he was alive. Many special medicines in the army were even made by him. He helped Feng Yuheng pour them together. He changed his life and thought he would never have the chance to see these things in later generations again, but he did not expect that his granddaughter would have mastered such a world.

Yao Xian was shocked, but he knew it was not the time to ask more questions, so he walked towards the secret operating room upstairs without waiting for Feng Yuheng to lead the way.

Feng Yuheng saw Yao Xian find the dark room with ease and pushing the wall into her, she felt relieved again. Grandpa came, so she would never be lonely in this world.

After returning to his senses, he immediately followed up. The grandparents and grandsons used advanced equipment and equipment to start carefully studying the extracted blood samples.

This process was not very long, and the bacteria did not mutate, so Yao Xian quickly found the key point. While listening to Feng Yuheng talking about his death and traveling through a sentence, he spent twelve hours, that is, six hours in ancient times, to develop a vaccine to resist the bacteria through blood bacteria samples.

During this period, Feng Yuheng went out once and told Xuan Tianming that she and her grandfather were taking vaccines in Qiankun, and that no one should come in.

Xuan Tianming personally guarded outside the tent, but under the report of the soldiers coming and going, he heard the news that one refugee after another had been infected with the epidemic.

He asked people to invite all the refugees out of the rain tent, try to breathe the air outside, and then gather all the people who have been infected with the disease in one tent, where there is a dedicated person to guard the tent, and no one is allowed to enter and exit.

After six hours, there were 300 refugees infected with the epidemic, including 18 soldiers.

At this time, Feng Yuheng and Yao Xian also came out of the pharmacy space. Yao Xian said to her: "Although the vaccine has been developed, it has not been tested and cannot be guaranteed to be successful. There are no conditions for animal experiments at present, and the only way is to use people."

Feng Yuheng frowned. She understood this principle, but there are dangers in human testing. Once the vaccine is not successful, it may endanger life.

In the huge clinic, only half-unconscious ghost doctor Song Kang was left.

Feng Yuheng pointed to Songkang and said, "This man is a doctor who is willing to do anything to learn medical skills. He has harmed many innocent people because of this. I thought that he has a high understanding in this regard, so he gave him a chance to make up for his merits. If he were not for him in this flood, I would be afraid that I would not be able to persevere." Feng Yuheng said and sighed, "It's a pity that he was the one who was first infected with the epidemic."

Yao Xian nodded and said to her: "This is normal. Exhaustion will cause a decrease in immunity. If he has more contact with refugees, the chance of getting infected will increase infinitely."

Feng Yuheng said again: "It is not fair to use who will do the experiment."

As soon as he finished speaking, Song Kang, who was half unconscious, suddenly moved, and his consciousness seemed to have recovered a little, and he kept shouting: "County Lord, County Lord."

Feng Yuheng quickly stepped forward, and before he could ask questions, Songkang said again: "Try me, try me."

Yao Xian asked him calmly: "Half the chance of death, are you willing?"

Song Kang nodded, "I am willing. I have killed countless people in my life, and although I have saved countless people, I still cannot withstand the killing. I am willing to try medicine with myself, but I have a wish that has not been fulfilled yet. If this wish is gone, even if I die, I can still make my goals."
