In ancient times, a long pavilion was set up every ten miles beside the official road, also known as the ten-mile long pavilion, for travel and rest. The long pavilion closest to the city was often a place to bid farewell.

Although it was almost evening, Du He insisted on setting off for Chang'an, and Du Gou and Sun Simiao sent them to Changting.

When the people heard that Du He was leaving, they also came to send him spontaneously. Du He's vaccination method quickly calmed down smallpox and saved Ci County. The people of Ci County were all grateful. They came to send him this time to express their feelings.

Although the long pavilion covered with thatch is simple, it can shelter from wind and rain.

The pavilion was full of people, with the people and the soldiers and yamen runners from the government. The scene was huge, with as many as ten thousand people.

In the pavilion, Du He and Du Gou stood with a cup of wine. Du Gou looked at Du He and said with a sigh: "After we parting today, I don't know when we will meet again. Brother Yu will send it here. Drink this glass of wine. May Erlang have a healthy future and no disasters."

Sun Simiao said: "The Taoist priest wishes Du Shaolang to be prosperous and prosperous, and spring is brilliant and summer is prosperous."

Du He smiled slightly and said, "Then I wish my brother a bright future and my grandson a hundred years old."

After saying the four words "Long Live" for a hundred years, he felt that it was not right. Sun Simiao lived 141 years old in history. He blessed him like this, and there was a suspicion of cursing him to die sooner, but he had already said that he was not able to change it. Fortunately, Sun Simiao didn't know how long he could live.

The three of them raised their cups together and drank the wine in the cup. This was the first time Du He drank the wine from this world. It was hard to say. He felt that the wine tasted very light, but instead had a strong sour smell, like an expired drink, and a bit like a rotten slurry, but he still forced himself to finish drinking it.

After drinking the wine, the three of them placed the wine cup on the tray.

Du Gou patted Du He on the shoulder and said reluctantly: "Let's leave, it's getting late, the future is long, don't delay the trip."

"Here." Du He crossed his hands and saluted them.

"Now." Du Gou and Sun Simiao both sang and returned the greeting.

Du He withdrew from the Changting Pavilion, turned to his carriage, looked at the sunset in the sky, and felt the scene of parting. He couldn't help but feel the feeling and sang loudly: "Outside the Changting Pavilion, beside the ancient road, the fragrant grass is green all over the sky. The evening breeze blows the willows and flutes sounds, and the sunset mountains are outside the mountains..."

He walked very slowly and sang very slowly. The melodious melody touched everyone's heartstrings. When he walked to the carriage, he just finished singing.

Although Du Gou didn't know what Du He sang, he could hear it. This was a farewell song, and the lyrics and melody were simple and easy to remember, and it was catchy. Du Gou's memory was good. After listening to it once, he could remember it roughly.

When the carriage started, Du Gou also started singing. Although some of the sounds were not very accurate, it did not affect the artistic conception of the song.

Perhaps Sun Simiao was infected, so he started singing along.

The singing seemed to be contagious, and all the yamen runners and the people also sang to say goodbye to Du He.

"...At the end of the sky, the corner of the sea, half of my friends fall, a pot of turbid wine will be gone, and the mountains outside the sunset mountain..."

Amid the singing, Du He's carriage went away towards the fiery sunset, as if it was flying into the sunset.

In the Tai Chi Hall of Chang'an, Li Shimin held two memorials and smiled at the ministers and said, "I have two memorials here, one from the governor of Xiangzhou, and the other from the magistrate of Ci County. Both of these two memorials say one person. Duke Ming of Lai (Du Ruhui), the second son of Duke of Lai, fought hundreds of bandits alone and won a great victory, and put down the last bandits in Ci County. Not only that, a smallpox epidemic occurred in Ci County, and five villages and towns were simultaneously out of the epidemic. The epidemic was fierce. Du He tried smallpox and created the vaccination method. Within one month, the major epidemic could not be cured. Although this vaccination method could not cure smallpox, as long as it was planted in ordinary people, this person would never suffer from smallpox."

As soon as this said, the palace was shocked. Liu Fanglin, the head of the Imperial Hospital, immediately stepped out and said loudly: "Your Majesty, this statement may be untrue. The problem of smallpox is because of the power of heaven and human power cannot be defeated. Du He does not understand medical skills, how can he create such a magical method? Old minister... don't believe it!"

At this time, someone else came out and said, "Your Majesty, although I do not understand medical skills, I also know that the brave bandits and hundreds of bandits are not able to compete with one person. The magistrate of Ci County Du Gou is Du He's brother. This is not what a good minister does. I ask Your Majesty to investigate thoroughly!"

Li Shimin smiled faintly and said, "If Du Gou reported his merits for Du He, why did Sima Zheng, the governor of Xiangzhou, also ask for me for Du He? It is exactly the same as what Du Gou said."

The man before said, "I think the Sima Governor was deceived by Du Gou and did not understand the truth. I beg Your Majesty to investigate thoroughly."

"This matter is naturally to be investigated." Li Shimin said slowly, "But Sima Zheng, the governor of Xiangzhou, said in his memorial that the medicine king Sun Simiao had been with Du He. Afterwards, Sun Simiao went to the Xiangzhou governor's office in person and was willing to testify for Du He that the vaccination method of vaccination has indeed effective epidemic prevention. Those who take this vaccine will avoid smallpox in this life without any trouble. Sun Simiao also clearly stated that this method was created by Du He personally, which is far better than the flower planting method created by the medicine king."

The two people who made the comments were stunned. Unexpectedly, the Medicine King Sun Simiao actually helped Du He testify. This is amazing.

Although Sun Simiao had not entered the officialdom, Sun Simiao's reputation was quite good in the court. It was because in the second year of Zhenguan, Empress Changsun gave birth to a prince Li Zhi, which was in danger, and the Imperial Hospital was helpless. Li Shimin sent someone to invite Sun Simiao. Sun Simiao first hangs silk to diagnose the pulse and accurately diagnoses the condition of Empress Changsun. Then he did not use any medicine, but used a silver needle and a few needles to allow Empress Changsun to give birth to the prince smoothly. Such medical skills shocked the Imperial Hospital. Li Shimin gave high rewards to senior officials and gold, etc. Sun Simiao did not take any of them and left behind countless legends in Chang'an.

Now anyone who dares to say that Sun Simiao’s testimony is not trustworthy, Li Shimin will definitely pull out a single tooth in his mouth.

The civil and military ministers in the palace whispered and talked for a while, and they were all curious. Why did Du He, who had always been famous for his dandy, suddenly made such a great contribution, suppressing bandits and quelling the plague, and creating such a shocking vaccination of cowpox. If this vaccine was really effective, it can be imagined that in less than ten years, the Tang Dynasty would not have smallpox again. What a great feat. This contribution is even better than the military achievements of destroying the enemy country. This alone is enough to let Li Shimin go to Mount Tai for the Fengshan Mountains.

When people are in a happy mood, Li Shimin's smile became stronger and stronger. He asked his ministers: "Tell me, how should Du He be rewarded to be worthy of such great achievements?"

After hearing this, the ministers started to talk again. If it were others, it would not be difficult to reward them. But when I was fifteen years old, I had not yet performed the title ceremony. I would be granted an official position, but I could not be granted money. It was too vulgar and it was really difficult to deal with it.

At this time, Wei Zheng went out and said, "The old minister thought that he could be awarded the title of Du He."

Wei Zheng is a tycoon in the court and is also a famous quarrel. When he usually discusses the court, he either makes the last statement, argues with his colleagues, and argues with Li Shimin. He has almost never seen him take the initiative to speak about the reward. But today he is abnormal and actually takes the initiative to ask for Du He for his title, and he is a title. You know, in the Tang Dynasty, it is far more difficult to be named than to be appointed as an official.

Li Shimin didn't expect that the first speech was Wei Zheng, and he was a little surprised, but Wei Zheng's suggestion was exactly what he thought, so he nodded and said, "It is no exaggeration to be named a marquis of the country for such great achievements, but... Du He is still young, and I think, what do you think is the first to be named Chang'an County?"

Liu Fanglin, the head of the Imperial Hospital Hospital, said loudly: "Your Majesty, the facts have not been found yet, so you should not be rushing to reward. I request Your Majesty to hand over the vaccination law to the old ministers, who are willing to try the vaccination law in person."

Liu Fanglin still doesn't want to believe that someone in this world can come up with a way to fight smallpox. Even if there is one, it should be Sun Simiao or an imperial physician. It is absolutely impossible for a playboy like Du He who does not understand medical skills. He must see it this time and be willing to believe it.

Li Shimin was not very happy to see that he was still in a bad mood at this time, but Liu Fanglin's suggestion was not wrong. He slowly said: "This memorial does not specify the details of the vaccination method. If you want to know the vaccination method, you must wait until Du He returns to Chang'an to know it."

Liu Fanglin said: "Then we have to wait until Du He returns to Chang'an and offer the vaccination method, and then discuss the reward."

Chu Suiliang stepped out and said, "I will discuss it!"

"I also agree!" Yu Zhining agreed.

"The old minister also agreed!" Kong Yingda agreed.

...

After many people agreed, Li Shimin turned to look at Changsun Wuji and Fang Xuanling.

Changsun Wuji and Fang Xuanling exchanged glances and both came out to discuss.

Seeing that both of them had agreed, Li Shimin nodded and said, "Since all the ministers want to see it is true, then that's what. After Du He returns to Chang'an to offer a wonderful method, he will as Wei Zheng said, and give Du He a title and give other rewards to him.

The ministers shouted: "Your Majesty is wise!"

………………………………

Du He has not arrived in Chang'an yet, and his reputation has reached Chang'an. The streets and alleys are discussing the vaccination vaccine method created by Du He. After all, this vaccine can prevent smallpox. How can the people not care about this important matter that benefits the people?

Cao Xiaojin sat in front of the divination stall and listened to the people around him talking about Du He, and couldn't help but stroke his beard and whisper: "Cowpox vaccine? Didn't he go to Ci County to find death? Why did he make this thing? Can he still prevent smallpox? Interesting..."

Du He rushed back to Chang'an all the way. After returning home, he took a warm bath, changed into new clothes, and had a big meal. After washing and eating, it was already dark and he went to bed and had a good sleep.

He slept for nearly six hours this time, and when he got up the next day, it was already four hours.

Get up and wash, eat and eat.

The Tang people only ate two meals a day, namely morning food and feeding (breakfast and dinner). The morning food was around 9 am and the morning food was around 5 pm. Most people eat morning food quite lightly, mostly for pasta and side dishes, but Du He was hungry on the road. Although he had eaten a meal yesterday, he still felt unsatisfied. Now he has to eat meat for him, and the kitchen hurriedly cooked mutton for him.

Du He likes to eat in the yard, put a stone table in the yard, and the steaming mutton is brought into the stone table in the side yard. Du He grabbed a lamb leg and chewed it hard. Although the taste is average, it is very pleasant.

Du Hezheng was able to eat hard, and the doorman Wang Xiaonian walked into the yard quickly and reported to Du He: "Young man, someone has handed a message to him."

Wang Xiaonian is Wang Dainian's cousin, only two months younger than Wang Dainian. He is quite lively, so he became a concierge.

Du He said: "My hands are covered with oil. Open it and let me see."

Wang Xiaonian opened the post to visit, and there were only a few numbers on it: "Du Gong’s old friend is visiting." The signature is "Li Family Erlang".

"That's it?" Du He felt that this visitation was too perfunctory and didn't want to see him, but he still wanted to ask, "Do you have a gift list?"

The ancients had great rules. Before visiting others, they not only had to hand in a greeting book, but also a gift list. The visiting book was to indicate the purpose of the visit, and the gift list was to express the sincerity and etiquette of the visit.

The gift list does not have to be much, but the gift is light and affection is heavy. The Du family was once a family of prime minister, and almost all guests who come to Du family to visit will deliver gift lists.

Wang Xiaonian shook his head: "No gift list."

When Du He heard this, he immediately pulled down his face and waved his hand directly: "Boll away, boom away."

Wang Xiaonian asked, "Shaolang, do I need to ask the person I come here to give me some advice."

Du He looked back at Wang Xiaonian and showed a look of praise. This kid is very good at doing things and actually knows to hint to the other party to give gifts.

Wang Danian, who was standing beside him, said inappropriately: "Xiao Nian, don't make trouble. How can our Du family ask for a favor with others? It's so unpleasant to spread it!"

"That's right! How could I ask if anyone has brought gift lists? This food look is too ugly..." Du He scolded Wang Xiaonian with a righteous look, but then Yufeng suddenly turned sharply and said, "Let's ask, what if he really just forgot."

Wang Xiaonian smiled knowingly when she heard this, raised her eyebrows and said, "If he hadn't forgotten, just send him away."

At first glance, he was a little difficult to understand. In fact, to put it simply, there are only two reasons why he didn't give gifts at home. One is that he forgot and the other is that he didn't want to give gifts. After giving some, he should understand whether the other party forgot or not want to give gifts. If he doesn't understand this, he will be too confused and can only be sent away.

Du He couldn't help but nodded and smiled: "You have a lot of wisdom, go."

"Here." Wang Xiaonian took the order happily.

Wang Danian watched his younger brother leave, and then asked Du He: "Shaolang, isn't it good to ask others for courtesy like this?"

"Why is it bad? I think it's good." Du He raised his eyebrows and said, "No one is asking about poverty in the downtown area, rich in the mountains have distant relatives. My Duke Duke's mansion, the prime minister's family, and a lot of relatives and friends who want to flatter me. I am so annoyed. I am keeping those who want to come and fight Qiufeng out and let sincere people come in."

"How can you be considered sincere?"

"Gift list." Du He looked as if he was taken for granted, "When you come to visit, you are swaying your empty arms, where is your sincerity?"

Wang Dainian was confused again. He felt that Du He's logic seemed to be not right, but he couldn't tell what was wrong.

Seeing that he still didn't understand his spirit, Du He felt a little disappointed and said, "You, elm-head, look at your brother, you know how to do things, you can learn from one thing at a time, and you can learn from it in the future. He will be more promising than you in the future.

"Ah? Oh." Wang Danian nodded in a daze, not knowing whether he understood it.

After chewing the legs of lamb, Du He could no longer eat anything else. He burped and began to think: "Since I am planning to live well in this world now, I must eliminate the hidden dangers that pose a threat to my life and the case of murdering my brother and I...it must be investigated."

He pondered for a moment, turned to ask Wang Danian: "Danian, is the boatman named Qiu who I asked you to lock up still here?"

Wang Dainian said: "I went to see it last night and I am still here. As you told me, the Du Guan family sent people to beat me every day, and there was no more meal."

"Well, Du Hong is still very good at doing things." Du He nodded with satisfaction.

At this moment, a noise suddenly came from outside, as if a quarrel was arguing. Du He frowned and puzzled, giving Wang Danian a look: "Go out and see what happened."

At this time, Wang Xiaonian ran into the yard with a panic expression and shouted anxiously: "Shaolang, it's not good, the person coming is so arrogant that he has broken in!"

"What!" Du He suddenly stood up when he heard this, feeling that his views were refreshed. This is the Duke Lai Mansion. His father was once the prime minister. Even if the person left, the tea was not cold yet. Who dared to come to his mansion to go wild?

"Let's go! Let's take a look! He'd better beat me today! Look, I can't kill him!"
