"What is this?" Empress Changsun picked up a porcelain vase, looked at it carefully, and looked at Li Yin.

  Li Yin said: "I call it perfume. Its function is similar to balm, but it is a hundred times stronger!"

   "Oh?" Empress Changsun is the mother of a country, but she can't escape the nature of a woman. She has been using shampoo since she used it, and she can't leave it at all.

   "The queen mother opens the magical effect of self-knowledge!"

  The eldest grandson gently uncorked the bottle, and a beautiful fragrance wafted out of the bottle immediately. The smell was refreshing and one couldn't stop. Balm is not an unfamiliar word in the palace, but the fragrance is far from it.

   "It's really fragrant!" Empress Changsun poured a little of the perfume on her hands, and a cool feeling spread. After the water evaporated, the rich fragrance still lingered on the palm of her hand.

  Li Yin was very satisfied with the effect, and he continued: "Previously, perfumes were too cumbersome to use, but this kind of perfume only needs to be applied on the body or clothes, and the fragrance will last for a day.

  Empress Changsun was even more amazed. According to what Li Yin said, she got a little on her clothes, and it was exactly as Li Yin said.

   "Min'er really took the trouble!" Empress Changsun looked at Li Yin with admiration.

  The gift was also delivered, and also taught the eldest grandson how to use it. Li Yin said: "I still have things to do, so I won't bother the queen to rest!"

  Empress Changsun nodded, "I will explain your matter clearly to the emperor, but you also have to remember to be strict with yourself, reflect on yourself frequently, and set an example for your younger brothers and sisters!"

   "I understand!"

   "Zhao Kai, send the sixth prince off for me!" Empress Changsun finally ordered.

  Following Zhao Kai to the gate of Yanxi Hall, Li Yin turned to Zhao Kai and said, "Eunuch, please stay! Thank you for leading the way!" He took out a twelve tael gold bar from his cuff and stuffed it into Zhao Kai's hand.

  Zhao Kai was taken aback for a moment, and then declined: "Your Highness the Sixth Highness, you are too polite, this servant is also following the Queen's order!"

"Father-in-law, you don't need to refuse. This little gold is insignificant to my Prince Liang's mansion. My father-in-law has served my mother wholeheartedly for many years. Even if my mother doesn't say anything, I also take it into my heart. This little gold is my gratitude to my father-in-law. It is a meager amount of money to buy tea." money!"

  When Li Yin said this, Zhao Kai couldn't refuse anymore, "The filial piety of His Royal Highness can be seen by the sun and the moon, so the old slave will be disrespectful!"

  Separated from Zhao Kai, Li Yin went straight to Concubine Yang's Ziyun Pavilion. Born in the emperor's house, he had to work everywhere. One more person to speak is one more help.

   Arriving at Ziyun Pavilion, Li Yin told Concubine Yang that he had gone to Empress Changsun first. Concubine Yang nodded and said nothing, but became interested in the perfume Li Yin was talking about.

   "It's really a miracle!" Concubine Yang kept sniffing the place where the perfume was applied on her body, and couldn't hide her joy. "This time, I'm going to let my mother promote it to you in the palace?"

   "Mother and concubine misunderstood, is such a fetish son still worried that he won't be able to sell it? I really want to honor you with all my heart!"

   "Slick tongue!" Concubine Yang rolled her eyes at Li Yin, "I was so mad at you last time that I forgot to tell you about one thing!"

  In Ziyun Pavilion, Li Yin stopped talking about the rules, sat at the table and ate pastries, "What's the matter?"

   "Do you know why your father is so angry this time?"

   "It's not that I don't like it!"

"It's nonsense again, your royal father originally booked a marriage for you. It is Cui Yingying, the eldest daughter of Cui Shao of the Boling Cui family. Inside, you never take our Li family seriously. Last year, your father ordered important officials in the court to compile the "Clan Records". Now, your father was furious. Although he forced the establishment officials to rank the Li royal family first, he still couldn't get rid of the knot in his heart. Later, he heard that the five surnames only intermarried within the five surnames. So I made a decree to propose marriage to the Cui family, who knows that Cui Shaoyin has always refused to answer, and you have caused such a scandal, your father was so angry that he locked you up!"

"Cui Lu Li Zheng Wang? The last nobleman in China?" This information flashed through Li Yin's mind immediately. After checking the history of the Tang Dynasty, he certainly understood the five surnames. In the Tang Dynasty, these five surnames were the real powerful families. , Seventy-eight out of ten officials in the court, and later Li Zhi also wanted to deal with these five families, but after reading the list of officials, he gave up. Later, in order to prevent the five families from intermarrying, he issued a "Marriage Prohibition Order" for the five surnames. ", but it is still useless, which shows the influence of these five surnames in the Tang Dynasty at that time.

   "I don't care about it!" Li Yin didn't have the concept of these aristocrats, and he didn't buy it at all.

Li Yin was acting foolishly again, and Concubine Yang was bitter: "You, you, the princes and nobles of the Tang Dynasty do not know how many people squeezed their heads to marry these five families, so they said that Cheng Yaojin, jumping up and down To curry favor with the dignitaries of the five surnames is not to marry the daughter into the family of the five surnames, so that the family will be honored from now on."

  Li Yin hates arranged marriages. Two people who don’t know each other at all will be xxoo at the first meeting.

   "Forget it, don't mention it, this matter is still pending." Concubine Yang shifted her attention to the perfume again, "It's very interesting, bring a few more bottles for mother!"

   "Okay!" Li Yin ate a plate of sweet-scented osmanthus cake, stood up and prepared to go back, "Tomorrow, I'll bring you a few more bottles."

  Leaving the palace, Li Yin did not go back to the palace, but went directly to the small hill in the west of the city. Li Yin and the others were put in prison, and this area has always been managed by Su Morer.

To Li Yin's surprise, when he arrived at the construction site, he found that the basic construction of the workshop here was completed, and only a few craftsmen were left to clean up the rest. Talking to a craftsman, the craftsman nodded frequently, his eyes full of awe.

   "How did you do it? The construction period was five days shorter than I expected!" Li Yin walked to Su Mo'er and said.

  Su Mo'er bowed her head, her face was reddish, "Mo'er only punished a few craftsmen, and rewarded a few craftsmen!"

   "It's more than that!" Li Yin wondered, although the workers' efficiency is higher, but it can't reach this level.

Su Mo'er continued: "Later, Mo'er saw that each workshop had its own group of craftsmen, and when a process was completed, the craftsmen in this process would be out of work, so I gathered all the craftsmen together, and each type of craftsman was Take turns working in the three workshops, and when this is over, it will be the next one, so that they will not be idle!"

   "Flowing water construction!" Li Min slapped his head, this Su Mo'er is really smart, he has come up with such an advanced construction method.

After the completion of the three workshops, Li Yin was in a good mood, and went back to the palace with Su Mo'er, but before he reached the gate, his carriage stopped leaving. Li Yin was surprised, and poked his head out to look, only to see his palace Seven or eight carriages were blocked at the door...
