"The special envoy, a person from Honglu Temple, sent a post saying that the young minister of Honglu Temple asked us to meet in three days." The servant came to report.

Lu Dongzan opened it and frowned and said, "Shaoqing of Honglu Temple? Du Shaoqing? Isn't this the person who is engaged to Princess Changle? What does it mean to be an appointment with us now?

People come quickly to investigate in the city and inquire about everything about Du Shaoqing."

After all, it was the prime minister of Tubo, who joined forces with Songtsen Gampo to unify the plateau. Lu Dongzan knew the truth about knowing himself and his opponent, but the results of the investigation shocked him. He originally thought that Du Shaoqing was just a diplomat, but he didn't expect that the other party had all his abilities, and his literary talent and medical skills were not included. He actually had a lot of military achievements in Hebei? When did a young man with all his talents in the Tang Dynasty have appeared again?

No wonder the emperor was so anxious to marry his daughter to him. This was obviously to tie him to the chariot of the Tang Dynasty and to reuse this person.

As Lu Dongzan said, after Du Shaoqing was granted marriage, he went to the palace to visit his wife and children, and also thanked the emperor and his wife.

In the Lizheng Hall, the princess smiled and asked her husband, "Husband, the father and mother are so reasonable and have agreed to your marriage with the Wu sister. How do you want to thank them?"

Du Shaoqing took out a small box from his arms and said confidently: "I have prepared it long ago. The Du family inherits the secret system, a three-day life-saving pill. No matter how serious the injury is, taking this pill can temporarily save your life. Although it is exaggerated to save your life for three days, you can at least have time to seek medical treatment.

This thing is a family heirloom, I won’t…”

The princess grabbed the box and said angrily: "No, how much pressure did the father and mother put on you? Just take such a pill?"

Well... Looking at his wife's rare temper, Du Shaoqing was amused, "Then how do you think I will repay you? Our family is poor and has only a newly built mansion. In addition, the three thousand taels of silver that His Majesty had rewarded before will be sent."

"You, you... husband, don't pretend to be confused. Your father is so kind to you. You must know that you just want you to help him in the court?

If you didn't want to do it before, then you are the son-in-law of your father. Even if you are for the sake of your concubine and children, you can't ignore your father-in-law's hard work and fatigue." Li Lizhi pointed at Du Shaoqing and shouted.

Du Shaoqing laughed loudly, who said that the water from his married daughter was poured out by the water? It seems that it is not working. The princess is pushing her husband forward for the sake of her parents' family.

He reached out and grabbed the princess Yubai's finger. Du Shaoqing smiled and nodded and said, "Mrs. I have given instructions. Of course, I dare not help but work for my husband. I just hope that my father-in-law can be more generous. If I make a mistake or something, don't punish me too harshly.

Alas, it’s just a pity that Luoxia Town has passed down the inn.”

Flirting with her husband in Lizheng Hall, the princess shyly pulled her finger back and comforted her, "The inn is still there. It's great that we can go to seclusion when we get old."

Du Shaoqing stretched out his right hand and said, "Since I am asking me to give my thanks to the court, should my wife return the elixir? That is a valuable family heirloom."

The princess immediately held the medicine box in her arms and laughed and scolded: "I think beautifully. You should respect the two elders such a valuable thing. Don't think I don't know that there is another one in the Wu sister. What kind of heirloom is what you use to deceive other girls."

At this moment, the queen came from the bedroom with her child and said to Du Shaoqing: "You kid took such a big advantage to us, and you beat us with a pill? Absolutely not.

If you go out and ask, let alone the Tang Dynasty, but even all dynasties, which prince consort can still have polygamy?”

Du Shaoqing's feet slipped and thought to himself, "Oh, the atmosphere of our couple is in full swing, and you are doing something bad again."

However, I am indeed grateful to my mother-in-law. If it weren't for the support of the queen, the mother-in-law, it would be difficult to tell the emperor.

"Boy, we promised your marriage, but have you prepared this betrothal gift? Wu'er is the most noble princess in the Tang Dynasty, and the betrothal gift cannot be shabby." The queen asked. This was not a joke, she was a little serious.

"My family only has 3,000 taels of silver. I wonder if it is enough to buy a betrothal gift?" Du Shaoqing replied.

"You're enough to marry a girl from the Wu family, but Wu'er can't do it. You have to think about it carefully. It's not that my mother-in-law is picky, but at least you can't let outsiders mock us for being shabby in marrying our daughter."

Du Shaoqing pondered for a moment and asked helplessly: "I don't know what my mother-in-law is missing? Please give me some advice, and the son-in-law will try to do it."

"What? This is the palace, and all the rare things in the world are here. Can the palace lack anything?" the queen covered her mouth and smiled.

At this time, Emperor Li Er walked in from outside, interrupted the queen and said, "I am short of everything here, money, grain, salt, iron, oxen, weapons, these things you can solve, I will agree to send someone to buy a betrothal gift for you.

I heard that you have made a surprise solution to the plowing ox problem in Hebei. I wonder if you can give me another surprise?"

Du Shaoqing turned around and greeted the emperor, thinking about what he could do. If it was as simple as wearing a bull's nose, maybe it would be really not difficult.

After pondering for a moment, Du Shaoqing asked, "I don't know what these things are most lacking in the Tang Dynasty?"

"Salt is undoubtedly salt. The Tang Dynasty broke its promise and the yield was extremely low. It was not easy to find a salt well or salt mine. Most of the people found were poisonous salt. So far, there is no salt available in some places in the Tang Dynasty. People barely use vinegar cloth to feed each day." Li Er sighed.

Du Shaoqing really didn't know about this. When he opened an inn, he knew that salt was expensive, but it was not that he couldn't buy it. He just spent more money in Zheng County, but he didn't know that it was because Zheng County, Huazhou was not far from Chang'an, and salt could be purchased from Chang'an, which was not short of it.

However, when it comes to salt making, Du Shaoqing really knew what he had learned in junior high school chemistry, "I thought it was grain, but I didn't expect it was salt. If it was poisonous salt, I had a way to improve it and turn poisonous salt into edible safe salt.

Another method is to take salt from seawater, called the salt drying method. The yield is huge and the method is simple, but the specific details require multiple experiments."

Really? Li Er exclaimed and immediately asked Du Shaoqing to explain in detail. Du Shaoqing drew a sketch and introduced the method roughly. Li Er was so lucky that he just wanted to try his luck to squeeze something from Du Xiaozi, but he didn't expect that he would really gain unexpected results.

"Hahahaha, boy, you're such a confused boy. Why didn't you tell me this method earlier? It's time to fight! If this salt-making method is successful, it will be more of a contribution than if you blackmail Goguryeo once." Li Er patted his son-in-law's shoulder and praised, and took the flowchart written by Du Shaoqing and walked out, unable to wait to experiment.

The queen and the princess looked at all this and looked at each other. It seemed that the dowry and betrothal gifts should have been purchased by the royal family.
