"Compendium of Materia Medica, Compendium of Materia Medica!" Xu Xian held his hands behind his back, shook his head and muttered loudly. Yun Yan lay on the windowsill, guessing what the man had thought of again, it was worth his trouble.

Qingluan was curious: "Brother, what kind of dish is the Compendium of Materia Medica?"

"Smack!" Xu Xian tapped Qingluan's head, and he found that he liked it more and more. He also taught: "The Compendium of Materia Medica is not a vegetable, but a book!"

"Don't hit me on the head!" Qingluan grinned and was indignant, it was enough to have a sister before, but now there is another brother, it's really unlucky!

Xu Xian smiled: "Do you want to spank?" His eyes also glanced at Qingluan's buttocks wrapped in a long skirt of water willows, and Qingluan's face suddenly turned red and he couldn't speak anymore. This brother is good, but sometimes it's too casual.

Yun Yan interjected: "The book "Compendium of Materia Medica", Yun Yan has never heard of it!"

Xu Xian smiled evilly: "Of course you haven't heard of it, because you haven't written it yet!"

Yun Yan was sullen for a while, but she was curious: "Is it that you want to write? Is it a collection of poems, but it sounds like a medical book!"

Xu Xian affirmed: "Smart, it is indeed a medical book, a medical book that is a hundred times more important than poetry!"

If Xu Xian plagiarized poetry to help himself choose a name, he used the technology of later generations to help himself make profits. Then this medical book is really for the benefit of the world, if it is a little shameful to copy the poems, then this book will not be embarrassed even if it is copied in full.

Xu Xian later also noticed the nearly 10,000 merits that had risen on the merit card, and sighed in his heart: Just by moving his thoughts, he has such merits, and if he writes it seriously, he is afraid that it will be immeasurable.

He also really hopes that this book can bring some benefits to the people of this era. In normal times, he would never have such thoughts, nor would he say such big things. He didn't want to be a saint, at best, he just wanted to be a good person.

Although he is a traverser, he rarely has any sense of responsibility as a traverser. First of all, this is not any dynasty in his memory, not the Great Song Dynasty, which is shameful of Jingkang, nor the Great Qing Dynasty, nor the Three Kingdoms in troubled times, naturally there is no danger in the world waiting for him to save.

I never thought about what capitalism I wanted to develop in the feudal society, [***]. Even if you don't remember all the words of a history teacher, you still remember the sentence: The material base determines the superstructure! Even if this sentence does not apply to another world, this difficult job is not at all accessible to ordinary people. What's wrong with the traversers, even if a hundred traversers go to play politics with Pan Yu, they will probably only be played to death. Is it true that you can become a great minister just by copying a few poems?

Therefore, Xu Xian has always been very content, and his behavior fully implements the excellent concept of "mixing and waiting for death", not seeking to become a king and a tyrant, and the harem is three thousand. Just want to become an evil landlord class, mix three wives and four concubines or something. But of course, the great ideal of three wives and four concubines is first because of Bai Suzhen, and then because of Pan Yu, who has been in a refrigerated state.

In short, the thankless task of compiling books is completely unsuitable for a hedonistic traveler like him.

And Xu Xian relied on the merit card to clearly remember all the information of this book.

"Compendium of Materia Medica": The author is Li Shizhen, 52 volumes, the whole book has a total of more than 1.9 million words, it took 30 years of painstaking efforts, an average of 19 crosses, although there are no eunuchs, but it is really a street to death, Li Shizhen ran to Nanjing at the age of more than 70 years, wanted to publish this book, but it was not published.

Later, he didn't even want the royalties and gave them to the court, and the court didn't take it seriously. It was not until three years after his death that it was successfully published, and then it was out of control, first in traditional Chinese (note: not in simplified Chinese), and then translated into five languages, and traveled all over the world. Hailed by Darwin as the encyclopedia of 1596.

This is also the fact that these medical skills were not valued in ancient times, and the workers, peasants, and doctors called it miscellaneous. Xu Xian also knew very well that if he told others now, it would take him a year to compile a medical book. Not only will no one support him, but they will laugh at him for not doing his job.

But it is precisely these miscellaneous studies that are the source of social progress! Whether it is the flint people to make fire or Dayu to control the water, which of the sages of the ancient period was not from miscellaneous studies. The ancestor of medicine and agriculture is the Shennong clan who tasted herbs.

Xu Xian has made so many famous poems and quatrains, and he has no merit at all, but he just wants to write a "Compendium of Materia Medica", and he has 10,000 merits. The aspirations of all the people can be seen. After all, poetry and painting also require a healthy body to play, and etiquette, righteousness and shame must first eat a full stomach before it can be done.

At this time, there was a knock on the door, Qingluan and Yun Yan's faces immediately changed, and Xu Xian said with a smile: "It shouldn't be my sister, Luan'er go and open the door!"

Qingluan hurriedly rushed to the door, opened the door and looked, but saw a woman in white smiling and said, "Excuse me, is this the mansion of Xu Xian and Xu Gongzi?"

Qingluan nodded dumbly, "Are you?" The woman's appearance made Qingluan also stunned.

Bai Suzhen smiled and said, "My name is Bai Suzhen, and I am a friend of Xu Gongzi!"

Qingluan had a very bad feeling, but such a person came to the door to find a man.

Although the world is open, there will be no such thing as binding and grounding, and women can go to the street at will. But it is not open to such a situation, a woman comes to the door to find a man.

But he still introduced Bai Suzhen into the door until Xu Xian was in front of him.

Xu Xian was pleasantly surprised: "Why are you here!" As soon as he wanted to learn flying skills, she came to the door, and she was really sleepy and someone sent a pillow.

Bai Suzhen blinked and said, "Aren't you welcome?"

Xu Xian said with a smile: "I begged for it, tossing and turning." That, let's go to the East Chamber to talk!" Her identity still has to be hidden for her, and it is inconvenient to learn the Dao by herself in front of Yun Yan Qingluan.

Bai Suzhen stretched out her finger and pointed at Yun Yan, who was standing on the side, in a sluggish state, and smiled at Xu Xian: "Xu Gongzi, is she Mrs. Zun?"

Xu Xian smiled and said, "Sort of!"

Yun Yan can be regarded as really sobering up, she is still very confident in herself, whether it is her posture or figure, but she feels a strong threat from the woman in front of her. A woman was able to come to the door alone and generously, and Xu Xian was so happy. I also have to go to the east wing with her to talk.

What that meant, she thought she knew. Could it be that this woman will come and ride on her head soon? She still remembers how her mother bullied her father's concubines, and that was really in dire straits! Could it be that she would also fall into that kind of sad situation?

She would never have imagined that once Bai Suzhen revealed her identity, she would naturally show the casual nature of a cultivator. Nowadays, it is not so much a woman visiting a man, but a Taoist friend worshipping the mountain gate. And Xu Xian just treats him as a friend.

Yun Yan said politely: "Little girl Yun Yan, I don't know what important thing Miss Bai has to do when she comes to my husband?"

Xu Xian was stunned for a moment and said, "What are you crazy about?" Except for the wedding night, Yun Yan never said the word "husband" again.

Bai Suzhen smiled and said, "There is something!" looked at Xu Xian who was standing on the side, and made a look. That means: Hey, your daughter-in-law is jealous!

Xu Xian looked innocent, what does this have to do with me! He didn't believe that Yun Yan would be jealous? Most likely he was worried about the identity of her concubine!

Yun Yan tugged at Xu Xian's sleeve and said coquettishly: "Husband, Yan'er also wants to hear it!" The voice was coquettish enough to make any iron-stone man turn into soft water, take her into his arms, and love her wantonly.

Xu Xian's heart was also rippling, but he quickly reacted, pulled his sleeves, and said: "What are you nervous about, I have something to talk about with others! Also, I have been teaching you cooking for several days, so you will do it at noon today!" and smiled at Bai Suzhen: "Let's go, I have something I want to ask you for advice!"

Bai Suzhen smiled and nodded, but glanced at Yun Yan again, worried that she would mind.

Xu Xian left Yun Yan and went to the East Chamber with Bai Suzhen. Yun Yan's face was pale and her expression was sluggish. Qingluan went over and patted her gently on the shoulder and said, "Miss, are you okay Yun Yan hugged Qingluan violently, and said wow-wow: "Luan'er, we're finished!" The sad life of the concubine was waiting for her. And when Xu Xian and Bai Suzhen introduced her, they reluctantly said the sentence "Sort of!" made her feel a little sad in her heart, am I really so unkind to you?

Qingluan said dumbfoundedly: "No!" It's just that she also knows that with the relationship between Miss and her brother, she is really not qualified to ask him for anything. And even if it is really related, Yun Yan is just a concubine. I have heard of wives preventing their husbands from taking concubines, but I have never heard of concubines preventing their husbands from marrying wives.

Bai Suzhen and Xu Xian arrived in the east wing, and suddenly said with a smile: "It seems that Mrs. Zun loves you very much! You should explain it to her well, don't let her worry." ”

Xu Xian also guessed what was going on, and said with a wry smile: "She just loves her current life!"

Bai Suzhen lightly stripped the ends of her hair and said, "If you love the current life, you will naturally love the person who brought her this life!" Although she wanted to persuade Xu Xian to abandon everything in the mortal world and practice hard, but thinking about the woman in Fangcai, she couldn't say it.

Xu Xian smiled silently, but this kind of thing could not be explained.

Bai Suzhen didn't want to be too involved in other people's family affairs, but she just thought to herself that Xu Xian and her wife didn't seem to be as affectionate as she imagined.

Of course, the two of them would not really go to the room to talk, even if they were cultivators, the taboo between men and women still had to be talked about. And at this moment, the spring is melting, and he sits on the stone bench at the bottom of the steps. Xu Xian asked, "You came today, have you thought of a way to repay your kindness?"

Bai Suzhen frowned and shook her head. She let Xiaoqing collect all the information about Xu Xian in the past few days, although she admired him even more, but she really couldn't find a way to repay the favor. Now I came to ask Xu Xian for advice.

What do you want?
