Hearing Li Er's explanation, Du Shaoqing nodded secretly. Although Prince Li Chengqian changed, as the crown prince, he naturally felt proud.

If he had to report everything to Chang'an after he went to the southwest, it would only prove that he was an incompetent person, and it would be despised by people.

After pondering for a while, Li Er said, "I want you to go to the Southwest to help Chengqian after the New Year."

Um???

Du Shaoqing opened his eyes wide and looked at Li Er in disbelief.

"Don't look at me like this. There are not many people who can use this matter, and Cheng Qian can accept not many candidates. After thinking about it, I'm afraid you are the only one who is the most suitable." Li Er sighed.

"No, definitely not." Du Shaoqing said fiercely, "Changle has a big belly, where can I leave? Father-in-law, you can't favor your son and ignore your daughter."

Du Shaoqing played the emotional card.

Li Er laughed and scolded: "Is I partial to you?

Look at the treatment of your Du family and Changle? Can other princesses have them? Can princes have them?

Indulgence is Chengqian as the crown prince, and my favor for him is not as great as that for Changle and Xuan Xuan.

Boy, you have to speak with your conscience!

Moreover, Chengqian is Changle's biological brother and his uncle who loves Xuan Xuan the most. Do you have the heart to see him in danger?

Putting aside personal affairs, if the crown prince is assassinated and dies, the Tang Dynasty will not be able to afford the losses. At the critical moment, you must distinguish the importance of it."

"It's still not possible. I'm just a doctor. I know nothing about the bodyguard. It's useless if I go!" Du Shaoqing insisted.

Li Er gave Du Shaoqing a sarcastic look, which means that whoever you know can do? The apprentices you taught in the clinic cannot hide them.

"Anyway, I can't go. Since the prince wants to practice in the southwest for five years, then judging the case and protecting himself should be one of the tests. Which emperor was not trained in danger.

Since he did not ask for help, it means he is confident. I guess he will not be happy even if I go." Du Shaoqing retorted.

you……

Li Er pointed at Du Shaoqing and smiled bitterly after a long time: "You are lazy and your life is a matter of life. You can also argue with it.

If Changle knows that you don’t go to save Chengqian, how can you still have the nerve to go home?"

Du Shaoqing was also helpless. His family knew his family affairs. When it comes to practicing medicine to save people, he was absolutely professional and authoritative. His other abilities were all mixed up with half a bottle of water. If he really wanted to stand alone, he would probably be absolutely weak.

After pondering for a moment, Du Shaoqing said, "It's better to send him a group of people and let him secretly form his own secret guard. It's easy to avoid hidden arrows and arrows. When he set off, he brought so many people, and they were still in the open place. Many things cannot be done by these people."

Li Er narrowed his eyes, stared at Du Shaoqing's eyes, and asked meaningfully: "Did you, Chengqian's teacher, have not taught these things?"

Du Shaoqing did not shy away and laughed: "One of the things I don't understand, two of the things I should teach. He is the prince. These things should have been taught by his father-in-law, but he didn't expect that he suddenly went to the southwest."

"You are modest!

You don’t have to talk to me so much. I can trust you. Even if you teach Emperor Chengqian’s mind, I won’t blame you.

It is no exaggeration to say that the trust in you boy is more than my trust in many sons." Li Er reached out and patted his son-in-law on the shoulder and said.

The old father-in-law said with sincerity. Although Du Shaoqing was moved, he dared not believe it.

"Forget it, since you kid doesn't want to travel far, then stay in Chang'an. If your talent is really limited to one city and one place, it would be aggrieved.

I will find another way to Chengqian. If he returns successfully after five years of experience, this last lesson..."

What happened to the last lesson? Li Er didn't continue, and Du Shaoqing didn't want to know. After all, five years later, Li Er was only forty-five years old. At the age of prosperity in the Spring and Autumn Period, could he abdicate after teaching his son?

After attending the family banquet in the palace, Du Shaoqing returned to his home and did not disclose the prince's affairs to his family at all. Like the emperor, he did not even tell the queen about these things.

The straight line from Chang'an to the southwest Tubo Road is thousands of miles away, and it is all rugged mountain roads. It is extremely difficult to transmit information. There is a way to be high and the emperor is far away. Even if something happens to the prince, it may take as long as one month to receive the news in Chang'an.

After thinking about it, Du Shaoqing felt that this was not possible. Unfortunately, there were no mobile phones in this era, and even radio stations.

Du Shaoqing, a medical student, didn't know how to make these things. At most, it was a popular basic physics, so it would be fine to build the most rustic generator, but the telegraph was difficult for him.

So in order to solve the problem of information transmission, he finally chose the ancient pigeon method, which is the simplest and not technically difficult.

The fastest transmission of information in the Tang Dynasty was the 800-mile rush, but that was also a messenger riding a horse, which was extremely inconvenient.

It is said that the means of sending messages by carrier pigeons were found during the Three Kingdoms period. However, after experiencing the disaster of the Five Barbarians invading China, almost all cultures have been broken, and many clever things have been submerged in the long river of history and have been lost.

When Du Shaoqing took out the pigeon transmission technology, Li Er was so happy that he had to reward him directly.

Why such a big reaction?

Because there was an unwritten saying in ancient times that information can be reached in one day, which is the core ruling area of ​​a dynasty, etc., where an army can reach in one month, that is, the farthest border that a dynasty can rule. It can be seen how important information transmission is in this era.

After Du Shaoqing took his children to pay New Year's greetings to the elders whom he knew in Chang'an, the princess returned home. That was, the child studied at Hongwenguan and had a master's degree with the Hongwenguan master, so she also had to visit Yan Shigu's house during the New Year.

Thinking of Old Man Yan, Du Shaoqing shivered for no reason, "Madam, what if you go on as your husband this year? After all, you are also a student of Master Yan."

Looking at her husband's embarrassing appearance, Princess Changle covered her mouth and laughed.

But this time, I didn't refuse, "Okay, I'll go with you this time. In fact, Master Yan is still easy to get along with. As long as you come to his house to abide by the rules and etiquette, you won't be independent."

"We must abide by etiquette and law. This time, we have to make sure that the old man can't find any fault." Du Shaoqing guaranteed repeatedly.

So the Du family drove a carriage to the Yan family in Chang'an City. The little girl Xuan Xuan went up to call the door in a cute little fox fur cloak.

When the doorman opened the door, he saw that it was a cute little girl with jade carvings and became curious.

Xiao Xuanxuan said politely: "Hello, I am a student from Hongwenguan. I brought my father and mother to greet Teacher Yan with my new year."

He was well organized and polite, and dressed in luxurious clothes. The doorman knew it was extraordinary at a glance. When asked for his name, the doorman hurriedly went in to report.

Yan Shigu was idle and was chatting with his two sons around the stove. When he heard that Du Xuanxuan was coming with his parents, the old man laughed silently, and only this child could say such inverted words.

"Let's go, the distinguished guest is here, and go out to greet him with your father." Yan Shigu ordered to his two sons.

"Father, a student is here to greet you. You are going out to greet me in person? I haven't heard of it. Which prince is coming?" The eldest son of the Yan family questioned.

The youngest son echoed: "Even the prince back then did not have such courtesy.

Father, just sit down and I’ll go out to greet you.”

Master Yan scolded with a stern face: "What do you know? The person who came was Du Shaoqing's son-in-law, Princess Changle and her daughter Princess Xuanyang. Ordinary people are not qualified to welcome her father."

What?

When the Yan family's second son exclaimed, the Yan family's eldest son had already rushed out. It was obvious that he was in a hurry to go out to greet him.

Yan Shigu's face turned dark and thought to himself that this eldest son was too snobbish. I heard that it was Du Shaoqing, so he was so panicked? He was not so active in greeting his father.

Seeing this, Yan Shigu knew that it was not appropriate for him to go out again, so he simply stood at the door of the living room and waited.

Du Shaoqing's family was so dizzy that he was picked up by a diligent and inconspicuous young man. Du Shaoqing was still thinking, who is this guy? He was so attentive that he thought it was the Du family, not the Yan family.

After hearing Yan Shigu's explanation, Du Shaoqing realized that he was the eldest son of the Yan family. After all, he was also a famous family that passed down from poetry and books. He was a bit too low-key.

"Boss, put away your philanthropist face, and you have lost all your face for your father." Yan Shigu scolded.

Du Shaoqing said in surprise: "Oh? So, Brother Yan is also a fellow businessman? I don't know what business he is doing?"

Yan Shigu explained with a dark face: "Everyone who says he is a businessman has praised him. If he doesn't read good poetry and books, he is just a greedy man and does everything. He will go wherever he has money, but he has accomplished nothing yet."

The boss of the Yan family was exposed by his father, and he blushed: "Dad, the first time the guest came to the door, you can't give your son some face? After all, the child has to walk in Chang'an, how can he survive in the future?"

Yan Shigu scolded: "You don't like to study, and you know that being forced is useless for your father, and you don't force it.

If you were a businessman for the country like Du Fuma, you would even burn incense to comfort the ancestors of the Yan family for your father. Finally, your descendants did not insult the reputation of the Yan family. But look at yourself, can you achieve success?"

The boss of the Yan family immediately lowered his head and muttered in a low voice: "I want you to recommend it and work with Du Fuma Du to make a difference, but you cherish your feathers too much. What can I do?"

Du Shaoqing and his wife never expected that the first time they came to this great Confucian family, they would encounter such a thing, which was a little embarrassed for a moment.

At this time, Xiao Xuanxuan curiously pulled the Yan family's boss' clothes and said, "Uncle, if you want to make money, you can come to me. He is the little god of wealth in Chang'an. I will ensure that you can make sure you make money in business..."

I……

The boss of the Yan family was embarrassed and seemed to be ridiculed by a little girl.

Yan Shigu said, "You are my student, he is my son. Don't call him uncle, just call him brother."

Xiao Xuanxuan bit her finger and said, "I don't have such an old brother."

Puff... The boss of the Yan family vomits blood!

Du Shaoqing said, "I am very interested in this Brother Yan. Anyone who loves something since childhood is not an ordinary person. Can I let me talk to Brother Yan?

How about letting Changle and Xuan Xuan talk with Master first?”

Yan Shigu didn't expect Du Shaoqing to say this, and he moved his heart and nodded, "It's rare that someone can still admire him. Shaoqing, you are called a business genius who has emerged from nowhere. Look at me and give him some advice."

He brought Du Shaoqing to the side hall, and the boss of the Yan family couldn't wait to rub his hands and said, "Mr. Prince Consort, I have long been acclaimed. You are the founder of a new painting. Can you draw a portrait?"

"Haha, Brother Yan doesn't have to be so polite. You and I are the same generation, and you can be matched by brothers.

Nowadays, new paintings are more popular. If Brother Yan wants a personal portrait, he can draw them everywhere. If Du draws another one, it may be a bit extra."

The boss of the Yan family said anxiously: "If there is no place, it will not be extravagant at all.

Brother Du’s handwriting, even the simplest avatar, has been quoted on the black market to 3,000 taels per picture, and it has a price but no market.

The Hongwen preaching picture you drew for your father last time, take a look below and let people estimate the price. Some people are willing to offer 18,000 taels of silver to collect, 18,000 taels... Tsk tsk!

If I hadn't been worried about selling it, I would have almost taken action."

puff……
