Yang Xianmao looked at the brocade box and found that there was a long cylindrical thing wrapped in thick flannel cloth under the box. Then he took it out again, and carefully unfolded it, but it was a cylinder of brass, half a foot long, about the thickness of a child's arm. He picked it up and looked at both sides and found that there were two small shiny crystal lenses at both ends of the cylinder, and there were black holes in them, but he didn't know what this thing was used for.

So he took it to his eyes, looked closely, and looked upside down, and it was full of flowers, and he saw nothing but a vague light.

He also noticed that there was a small nut next to the cylinder, and when he turned the nut by hand, the blurred light inside would change, but it would always be blurry.

Yang Xianmao looked at Gonggong Huang suspiciously.

Huang Gonggong smiled and said, "This thing is called a crystal cylinder mirror, and there are polished crystal lenses on both sides, and I don't know what is in it, because it is sealed and dead." As for what this thing can do, I'm sorry, and I don't know. At that time, when Lord Lu Duan took it out and showed it to me, I also pondered for a long time, and the adults themselves didn't understand that this thing was bought with the crystal convex mirror. The Persian who sold things didn't know how to talk about our Middle-earth, so Lord Lu didn't understand what he was saying after listening to it for a long time. He only knew that this thing was a treasure and could see things, but he couldn't figure out how to look at it. ”

Yang Xianmao pondered for a while, this crystal cylinder mirror doesn't know how to use it, whether it can be used is not sure, the crystal convex mirror is very useful, although he is now super eyesight, he can see very small things clearly, but it is also limited, if you add this magnifying glass, you should be able to see smaller things. This is very useful when doing surgery, for example, when doing eye surgery, you can see the direction and direction of the suture needle more clearly, and when the blood vessels are sutured, you can suture smaller blood vessels, and reconnect the blood vessels as much as possible, which is very helpful for the recovery of the body.

Yang Xianmao immediately thought of the use of this crystal convex mirror, and in the future, it can be made a scaffold and placed on the part of the patient to be operated on, so that the small parts of the surgical field may be seen more clearly.

As for the crystal cylindrical mirror, let's ponder it slowly, since the Persian merchant can sell this thing for a lot of money, there must be something different about him from ordinary objects.

So Yang Xianmao was about to put the cylinder back in the box, and found that there was another thing underneath, which was also wrapped in red silk, which was very precious, so he put down the cylinder, picked it up and opened the red silk, but inside was a thread-bound book with yellowed paper. At first glance, it is a very old thing, and the seal on the cover reads "The Classic of Mountains and Seas".

"The Classic of Mountains and Seas" is known as the first strange book in ancient and modern times, recording all kinds of mythical beasts and monsters, as well as medicines, sacrifices, etc., although magical, but there have long been circulars in the market, and you can buy them from the bookstore at will. Yang Xianmao had read it all before, and when he flipped through it, it was no different from the version in the market, the only difference was that the book in the market was an engraved copy, and this one was a neat handwritten copy.

Since it's all over the place, it's not a treasure book, so why do you put it in a box so carefully and send it to yourself as a treasure?

Gonggong Huang saw Yang Xianmao's doubts, and immediately smiled and said: "Before coming, Lord Lu told the miscellaneous family that this book was obtained from a Taoist temple destroyed in the war in Chibifeng, not far from Xuanzhou, when he accompanied the emperor on the expedition, the Taoist temple chief was injured by the rebels and his life was in danger, so he handed the book to him, saying that it was the treasure of the town hall, and asked him to keep it for fate." But he studied it carefully, and couldn't find anything special. Master Lu said that he is very fated with you, since it is left to fate, then give these three things to you, a destined person, maybe you can rely on your ability to solve the mystery. ”

Yang Xianmao arched his hand and said: "Thank you father-in-law, please ask father-in-law to convey to Lord Lu on his behalf." ”

Huang Gonggong smiled and nodded: "Don't worry, the miscellaneous family will bring Childe's words to Lord Lu, listen to Lord Lu, you have also done him a great favor, from his words, you can hear that you have really helped a lot, and he is also very grateful to Yang Gongzi for you." ”

After another moment of greetings, Huang Gonggong got up and said goodbye, going to supervise the disaster relief and grain release.

After sending away Huang Gonggong and Hu Tongju and others, Yang Mingde was very happy, returned to the pharmacy, called Yang Xianmao over and said: "I can't imagine that since you have known the important ministers of the court, and even the eunuchs around the emperor appreciate you so much, our Yang family will rely on you for the glory of the ancestors in the future." ”

Yang Xianmao smiled and said, "Actually, I just happened to help him, he actually fell in love with him, which shows that this adult is a person who values affection." ”

Yang Mingde nodded and said: "Today, our family has the father-in-law of the Great Song Palace, as well as the general judge of the Yamen, you have met Lord Lang Zhonglu again, and I am very happy for my father, we have to cook a few dishes, drink some wine to celebrate, and comfort the ancestors and ancestors, the Yang family has your descendants." ”

The whole family laughed.

From this day on, their pharmacy was in full swing, and there was an endless stream of patients who came to their pharmacy every day to seek medical advice, more than before the crackdown. It's just that except for Assistant Teacher Yao and others who know the reason, almost everyone else doesn't know.

That afternoon, Wen Xin finished painting and walked out of the boudoir of her medicinal herb warehouse, and saw that Hongsheng'er was still holding the oval crystal convex mirror in her hand, which was very rare. Seeing her come out, Hongsheng'er jumped over and said to Wen Xin'er: "Sister Wen, the young master has a baby, this is it, he can look at things as the boss, you see!"

Hongsheng'er put the magnifying glass on the table and put the prescription sheet written by Yang Xianmao, and the handwriting on it immediately became much larger.

Wen Xin glanced at it, smiled faintly, and was noncommittal.

Hongsheng'er didn't know that this Wenxin girl turned out to be the princess of Wu Yueguo, and there was already this kind of crystal convex mirror in the palace of Wu Yueguo, which also came from the Western Regions such as Persia and Dashi. Wen Xin has seen it since she was a child, so naturally it is not rare, but this one is a little bigger than the one she has ever seen, which is a bit surprising.

Seeing that Wen Xin was not very interested, Hongsheng'er pursed her lips, rolled her eyes, and said, "By the way, the young master also got a treasure, but we have been thinking about it for a long time, and we don't know how to use it." Sister Wen, do you want to help take a look?"

Hongsheng'er didn't care whether Wen Xin agreed or not, so she ran to take out the crystal cylinder mirror, handed it to Wen Xin with both hands and said: "That's it, the father-in-law who delivered the decree said that Master Lu, who gave this thing to the young master, said that he bought it from a Persian merchant, and the Persian merchant said that this thing can see things, but we can't see it no matter how we think about it, and we don't know how to use it." ”

Wen Xin took it, looked at it repeatedly, and also picked it up and looked at both ends, but she couldn't see anything.

She has a stubborn personality, and the more difficult things are, the more she wants to solve them, so she was not discouraged, and stepped into her small boudoir in the medicinal herb warehouse with the crystal cylinder mirror.

Hongsheng'er followed and looked over, and saw Wen Xin sitting at her desk where she was writing and painting, turning over and over to study the crystal cylinder mirror. So he stuck out his tongue, and did not bother her, but went back to his own business.

Hongsheng'er went to the kitchen to help Zhang's cook and stir-fry, and the pharmacy's business gradually improved, and she could already eat white rice, chicken, duck and fish, and Hongsheng'er was busy in the kitchen.

Yang Xianmao has been pondering how to design a shelf to place the crystal convex mirror to help with delicate surgery. Seeing that in the evening, the patients were gradually becoming scarce, Yang Xianmao took the crystal convex mirror, took a carriage to the carpenter's shop, and ordered a wooden shelf that could place the crystal convex mirror, which should be able to extend to the middle of the operating table, so as to see the operation clearly.

Not long after Yang Xianmao left, Wen Xin, who had been studying the brass pipe in his boudoir, walked out of the boudoir, his face was a little pale, as if he had seen something terrifying, standing in the lobby of the pharmacy, looking for Yang Xianmao. I didn't see it, so I came to the kitchen, beckoned Hongsheng'er over, and said, "Didn't you say that you don't know how to use that crystal cylinder mirror?"

When Hongsheng'er heard this, she couldn't help but be overjoyed, and said, "Sister Wen, have you figured it out?"

Wen Xin was not as elated as her, but her face was afraid, and she whispered: "What can be seen in that crystal cylinder mirror is too terrifying. Don't look at it!"

Hongsheng'er found that Wen Xin's face was ugly, she had always thought that Wen Xin would not blink her eyes before Mount Tai collapsed, as if there was nothing in the world that could cause her feelings to fluctuate, but she didn't expect that this time, actually, seeing the fear in her eyes, she didn't feel a little strange.

So, Hongsheng'er wiped a pair of small hands on the scarf, walked out of the kitchen quickly, went straight into Wen Xin's boudoir, and came to the big desk. She had seen the crystal cylinder mirror strapped to the pen holder on the table, and placed on the table, on the pedestal directly below the crystal cylinder mirror, with some water stains. She looked at it curiously.

At this glance, I couldn't help but shudder with fright, and screamed out. But it turned out that she saw in the mirror, there was a monster covered in fluff, swimming around in the water.

Hongsheng'er was so frightened that she took a few steps back, almost sitting down in the pile of medicinal herbs. Finally stopped, caressing her plump breasts with her right hand, and looked nervously at the pedestal at the foot of Beacon Hill, but there was no terrible monster on the pedestal. She looked around again, but there was still nothing.

Are you dazzled?

Hongsheng'er leaned up again and looked in the mirror, and the terrible monster was still swimming in the water, which frightened her again, and quickly looked up and took a step back. She wondered, could this monster be in this cylinder?

At this time, Wen Xin walked in, pointed to the water stains on the base of the pen holder at the front end of the crystal cylinder mirror, and said, "That monster is in the water, and it is invisible to the naked eye." ”
