Zhang Zong chatted with Princess Chengyang for a long time. In addition to Ning'er's incident, Princess Chengyang was also more worried about Zhang Zong. She was mainly worried that Zhang Zong and Taiping had disagreements and would have conflicts after marriage, so she also advised Zhang Zong to be generous and not to be too harsh on Taiping as long as it does not involve the issue of principle. This is also the way for couples to get along.

Zhang Zong just nodded perfunctorily about Princess Chengyang's advice. He had not considered peace yet. Maybe he instinctively refused to think about this matter, so he would take one step at that time.

Finally, when Princess Chengyang left, she also reminded Zhang Zong to think about driving, and then she left here by car. She had to rush to the imperial tomb overnight. Even if it was too late today, she could still worship her sister tomorrow.

Watching Princess Chengyang leave, Zhang Zong also turned around and returned to the room. He felt very tired, so he didn't even eat dinner and fell asleep on the bed. However, he seemed to have had many dreams during this sleep. When he opened his eyes and woke up, he only remembered a little bit of the scales and half of the claws in the dream.

In the next few days, Zhang Zong had to do more things, and almost all the officials from the Ministry of Rites were living in his house. Not only did he have to learn etiquette, but he also had to go through the entire wedding process.

In addition to the people from the Ministry of Rites, the Imperial Medical Office also sent people to learn how to grow cowpox. Zhang Zong also took time to demonstrate the process of growing cowpox to them. Several young medical officials even asked Zhang Zong to grow cowpox for himself, saying that he wanted to experience the reaction after growing cowpox. This made Zhang Zong admire them very much. No matter which era, there were a group of warriors who dared to be the first in the world.

The process of growing vowel is actually very simple. It is nothing more than scratching a wound on the skin and applying dried vowel powder. Of course, there are some things to pay attention to throughout the process, such as the most important thing is hygiene. The knives used for each inoculation need to be disinfected to prevent cross-infection. After all, in this era of backward treatment, God knows who has what virus is on them.

The disinfection method is also very simple. You can use alcohol or sterilize at high temperature. Finally, Zhang Zong decided to hand over the preparation method of alcohol to the Imperial Medical Department. High alcohol can be burned and made into an alcohol lamp to disinfect the knife. In addition, if the ratio is appropriate, medical alcohol can also be used for surgical operations.

The process of growing cowpox is very simple, but the extraction of dried cowpox powder is very difficult. After all, this thing can only be extracted from cows. Although Li Hong drew a batch of cows from the imperial village, he could only produce a small amount. This output can only be supplied to a very small number of people. Not to mention the whole country, it can't even supply Chang'an City.

Zhang Zong was also very troubled about this problem, but there was no solution for the time being, so he could only hand over this matter to the Imperial Medical Office. As for the mass production of dried cowpox powder in the future, it is estimated that he will have to wait until he finds a way to solve it in the future.

The day before the wedding, the officials of the Ministry of Rites who came to trouble him every day finally stopped coming. After all, they will be getting married tomorrow and they have done everything they should do. Zhang Zong probably knew they were exhausted, so they gave Zhang Zong a vacation on the last day. After all, getting married tomorrow is even more troublesome, so they need to leave some rest for Zhang Zong.

However, Zhang Zong was obviously too optimistic. Although the people from the Ministry of Rites did not come, the people in the palace came. And there were a few older palace maids, all of whom were old-fashioned and said that they had been ordered by the Queen of Heaven to teach Zhang Zong some necessary etiquette before marriage.

At first, Zhang Zong was quite surprised. After all, he had been learning the etiquette before marriage for so long, and the people from the Ministry of Rites were no longer here. Why did the people in the palace teach etiquette again?

However, after several older palace maids took him into the room, they took out several albums from the box they brought. When Zhang Zong saw the contents of the album, he couldn't help but look speechless on his face. He finally knew what the so-called pre-marital etiquette was.

The album is full of pairs of men and women who are not dressed in clothes. To put it simply, it is actually a erotic picture, and the paintings are also very exquisite, and at first glance they are from famous artists.

However, although it was a erotic palace, the older palace maid picked it up very seriously and explained it to Zhang Zong page by page. In fact, it was a very basic gender knowledge. Zhang Zong was so familiar with this thing. After all, he had too many textbooks hidden in his computer in his previous life. What posture had he seen before?

Of course, Zhang Zong doesn't need these as an old driver, but it doesn't mean that everyone understands it. In fact, at this time of the Tang Dynasty, men and women were married early, and many people were not yet mature, and they only had some ignorant impulses about men and women. Therefore, it is very necessary to explain some physiological knowledge to them before marriage.

After finally waiting for these older palace maids to finish the erotic pictures, Zhang Zong thought it was over, but he didn't expect that they took out a few wood-made villains from the box, and their joints could move, which looked very realistic, with the characteristics of men and women, and then demonstrated them to Zhang Zong, which made Zhang Zong a little amused.

After the last few palace maids finished the demonstration, Zhang Zong felt as if he was relieved and immediately sent them away. However, as soon as these palace maids left, a group of eunuchs and palace maids came, and brought the wedding dress that Zhang Zong would wear tomorrow. In fact, Zhang Zong had tried this wedding dress long ago, but it was taken back to the palace and was not sent here until today.

It can be said that after the struggle of this day, Zhang Zong felt more tired than usual. After finally waiting until the evening, the group of people stopped and Zhang Zong could finally sit down and take a breath. However, the people in the palace did not leave, but wanted to guard Zhang Zong, so that they could put on makeup and put on wedding clothes tomorrow morning.

"Thank you for your hard work, take a little water!" At this time, Wan'er finally had time to pour them a cup of tea and bring them up. She looked at Zhang Zong's eyes with a lot of heartache. After all, she saw Zhang Zong's hard work during this period, and Zhang Zong had just recovered from a serious illness, which made her worried that Zhang Zong would relapse.

Zhang Zong picked up the tea and drank it all, then he let out a long sigh, then showed a gentle smile to Wan'er and said, "Wan'er, you have worked hard during this period!"

"Compared with the young master, Wan'er did nothing at all, but tomorrow is the day of the wedding. After tomorrow, the young master can take a break!" Wan'er stepped forward again, then gently pounded Zhang Zong's back.
Chapter completed!
