The emperor flipped through these books roughly. The books mainly recorded the reform of agricultural tools, some grain planting methods, how to fatten livestock, etc.

Although other things are not confirmed yet, and we don't know if they are as written in the book, several of the tools are very useful at first glance, especially the waterwheel and the thresher. These tools not only have clear production methods, but also have pictures next to them. This picture was drawn by An Ning with charcoal according to the illustrations in the book.

The emperor asked, "Yongjia, did you write all these books yourself?"

An Ning was embarrassed to say that she wrote them herself, so she just said, "Your Majesty, these books were not entirely written by me. They were mainly compiled based on the notes of my ancestors and the experience passed down by my ancestors."

The emperor knew that An Ning was being modest. As an emperor, he did not only read books of sages, but also dabbled in all aspects, especially books on farming. He did not say that he had read all of them, but he had at least read most of them.

Moreover, the collection of books in the palace was much larger than that in the private sector, but he had never seen what An Ning wrote in the book, so he thought it was just An Ning's modesty. The emperor smiled and said, "Yongjia, you have contributed a lot by presenting the book, what reward do you want?"

An Ning shook her head and said, "Your Majesty, I just don't want to see the people go hungry, so I presented this book to you."

The emperor was very pleased with An Ning and said to Chen Zhong, "Reward Princess Yongjia with 1,000 taels of silver, two boxes of gold, silver and jewelry, and ten bolts of silk and satin." Then he turned to An Ning and said, "I will ask the officials in charge of agricultural affairs to study these books carefully. If all the things in the books are useful, I will reward you generously."

An Ning quickly bowed to express her gratitude.

An Ning left the palace with a large number of rewards, which again attracted speculation from various noble families. They wondered what Princess Yongjia had figured out to make the emperor so happy. However, speculation was speculation, and everyone once again saw how favored An Ning was.

As soon as An Ning returned to the mansion, Butler An came to An Ning with a bunch of invitations. An Ning looked through them and saw that it was either a flower viewing party or a birthday party. An Ning asked, "Which of these must I go to?"

Steward An pulled out an invitation and said, "This is the birthday banquet of the old lady of the Taifu family. This old lady is the mother of the Queen. The princess cannot refuse this honor."

An Ning took the invitation and said, "Okay, then turn down all the others!"

Butler An said, "Yes, Princess." Then he bowed and left.

An Ning took out two silver ingots of ten taels from the rewards he had just brought back, and said to Bi Yu beside him: "You have made a contribution this time, this is a reward for you."

Biyu quickly bowed and expressed her gratitude, saying, "Thank you, Princess." Biyu was very happy to receive the reward. Although she was a government slave and could not redeem herself, she had the money and her life would be better in the future.

An Ning smiled and said, "Okay, you go down and have a rest first!" Biyu bowed and retreated.

An Ning thought that all the books in her pen and ink shop were hand-copied, which showed that there was no printing technology in that era, so she returned to her room and found relevant books about movable type printing from the space.

After studying it carefully, An Ning found that movable type printing was not very difficult, so he called Butler An and said to him, "Go find a few craftsmen who can make porcelain. I have some things I want to make."

Butler An never questioned his master's decision, so he nodded and said, "Yes, Princess, do you have any other instructions?"

An Ning thought for a while and said, "Let's build another kiln. What I want to make needs to be kept secret for now and cannot be known to others."

Butler An nodded and said, "Yes, Princess, I'll arrange it right away." Then he walked out.

Because Gao and An Dashan were not at home, An Ning had lunch in her own yard at noon. After lunch, An Ning rested for a while and then went into the space to see if there were any books that could be taken out to present to the emperor.

An Ning looked around and found a few military books. These were good things, so An Ning decided to copy them down by hand and give them to An Yong and Gu Qingxuan. After putting the military books away, An Ning found a book about making cement. This was also very useful. He took it out first and asked Biyu to write it down when he had time.

Looking at the book in his hand, An Ning felt that it was enough, so he left the space, spread paper on the desk, and began to copy the military book. This took more than an hour, and when An Ning put down the pen, he found that it was already dark outside.

An Ning stood up and stretched, and found that her stomach was growling with hunger, so she asked Xiaomei and Xiaolan to bring some food. After dinner, An Ning walked around the yard for a few laps to digest the food.

When An Ning felt that her stomach was not so full anymore, she asked Xiao Mei and Xiao Lan to get some hot water and took a comfortable hot bath. After taking a bath, her fatigue was washed away. An Ning changed into a clean set of underwear and then lay down on the bed to sleep.

Three days later, Gu Qingxuan received a gift from his fiancée. Gu Qingxuan opened the brocade box with some joy and found three books inside. He flipped through them curiously. He was surprised to find that these were military books. He quickly started reading the book from the beginning. He forgot the time when he read it. When his personal guard came to report that it was time to eat, Gu Qingxuan realized that it was already noon.

Gu Qingxuan put the book away reluctantly, then ordered the guards at the gate not to allow anyone to approach the study, and then came to the old marquis's yard.

The old marquis looked at Gu Qingxuan's smug expression and said, "I heard that Yongjia sent you a gift?"

Gu Qingxuan nodded. This matter was aboveboard and not a private transaction, so there was nothing that could not be acknowledged. The old marquis did not say anything more and the two finished their lunch in silence.

After lunch, Gu Qingxuan went back to the study. Although the old marquis was curious, he did not ask any further questions.
