After there is a mold, the processing is very simple, and the specific production and processing will be left to the family to do after the experiment is successful.

"Young master, Yanbei is back." The sound of colorful clothes came from outside the old house.

Won-sun walked out, covered in oil and some pungent smells.

"Young Master, what's wrong with you." Caiyi said with concern.

"It's fine." With that, Yuan Shan changed his clothes and rode back to the mansion on a tricycle.

"Yanbei, nothing happened to you along the way." Wonsun asked.

"Young master, we're fine, it's just that it's difficult to walk in the mountains that has delayed for so long." Yanbei returns.

"Young master, these raw materials were pulled back from over there." Yuan Shan listened to Yanbei say, and then looked at the wheels of the carriage that had been worn out.

After Yan Bei's narration, I realized that it was too difficult to go south, and one of the spare wheels of this carriage was ground like this, and it was really not easy to come back smoothly.

"Shu Road is difficult, it is difficult to go to the blue sky." Yuan Shan sighed.

"Well, it's good to come back smoothly, I'm not sure if these raw materials are or not, I'll ask someone to take them and burn them later." Yuan Shan said.

There are two ways to get antimony trioxide, dry method and wet hair, the dry method is to fire the Huidi ore, and the obtained steam will be obtained after cooling, and the other is wet hair, which requires distillation, hydrolysis, ammonialysis, separation, precipitation, drying and a series of processes are obviously more complicated, so the dry method is decisively used.

He is not sure whether these raw materials are Huidi mines, they are all remnants, he is not a mineral expert, so he can only come with an attitude of trying, and in order to ensure that there are no mistakes, Yanbei and others have divided these raw materials into categories, and the places where the raw materials are collected are also different, so they can only try one by one in order to find the Huidi mine.

Ordered people to do these things, and recorded all the experiments one by one, the family couldn't do this thing, and few people were literate, so this matter was also ordered to be done by Steward Zhou himself.

When he returned to the inner courtyard, he first changed his clothes, and at this time, Qianyu's injuries were almost healed, and he could walk freely, and this time he was talking to Dugu Ruolan about something.

"Husband, don't go out yet, Ruolan has something to discuss with you." Yuan Shan was just about to go out when he was stopped by Dugu Ruolan.

"Tell me something." Yuan Shan said immediately.

"Qianyu's marriage." Dugu Ruolan said.

"This matter is a little bit arranged, Qianyu, what do you think?" Yuan Shan sat down and looked at Qian Yu and said.

"I have no opinion." Qianyu replied.

"Husband, leave this matter to Ruolan, and arrange it in the manor when the time comes, and I will ask someone to clean up the other room in the main house." Dugu Ruolan said.

"Okay." Yuan Shan said, in fact, that room is going to be converted into a gym, since there are two ladies, he can't always live in the same bed, he is busy these days, otherwise he would have been impatient.

These things will be handed over to Dugu Ruolan to deal with, anyway, just prepare it in the manor, it is completely different from the first time he married a wife, although he nominally arranged a flat wife for Qianyu, but his status is actually higher than that of a concubine, but Yuan Shan will not think so.

After finalizing this matter, Yuan Shan was very happy in his heart, marrying a wife is a proud thing in life, and when he came back from the evening, he saw Qianyu standing in the inner courtyard.

"Qianyu, there are so many mosquitoes outside, why are you standing here." Wonsun asked.

"I'm waiting for you." Qian Yu said.

"Wait for me, hehe." Yuan Shan wants to go up and set the sleeve almost.

"I have something to tell you." Qianyu said with a straight face.

Yuan Shan looked at Qian Yu with a cold expression, and said, "If there is anything, you can say it, as long as it is your matter, I will definitely help you solve it." ”

Qianyu's body suddenly moved slightly, and she waited for a while before she said: "My real name is Du, my father is Du Fuwei, I am the daughter of a criminal minister, Du Qianyu, if it wasn't for the princess to save me in the fifth year of Wude, I'm afraid I would have ...... long ago."

"General Du Fuwei, can you tell me what the hell is going on?" Yuan Shan said.

He didn't know much about this Du Fuwei, but he had heard the name of this person somehow, and he was also a powerful character, and he said in his heart that this Li Yuan was really uncomfortable, and he invisibly became the enemy of his father-in-law.

"In the fifth year of Wude, my father entered the court to report on his work, and the left general Fu Gongqi rebelled against the military power of the Southeast Province, and lied that he was at the behest of his father, and his father was framed, and finally died violently." Saying that, Qianyu actually left tears.

Yuan Shan let her cry on his shoulder, and comforted him softly: "Don't think about these unhappy things, but I really have to thank Her Royal Highness the Princess, otherwise I wouldn't have been able to meet you now." ”

"As the daughter of a criminal minister, if the Hou Ye marries Qianyu, I'm afraid it's not appropriate." Qian Yu said softly.

"What's wrong, didn't Li Xiuning say it, rest assured that she is the princess of the Tang Dynasty, who dares to find fault with her words, and even if there is no her, this marquis likes you, then marry you, you are all temperamental, don't care about so many miscellaneous things, about your father's affairs, I will ask someone to investigate, and I will definitely be able to clear your father's grievances and you when the time comes." Yuan Shan said.

"Okay, don't talk about that, let's go back to the house, there are a lot of mosquitoes, it's time to get some mosquito coils." Yuan Shan walked back with Qian Yu, talking as he walked.

"What is a mosquito coil?" Qian Yu asked.

"Mosquito coil is a kind of incense for smoking mosquitoes, you go into the house, I'll go to the study to get mosquito coils." Yuan Shan said and quickly removed the inner courtyard.

I bought some mosquito coils in the mall, unpacked them and recycled them back into the mall, two pennies a box, and the money recycled was almost insignificant.

It is said that the earliest mosquito coils are from the Song Dynasty, which are made of realgar and mugwort leaves, while modern mosquito coils are pyrethroid insecticides, even if it is a slight toxin, it is also poisonous.

I didn't care too much about the Dragon Boat Festival in Datang, and the mosquitoes began to increase at this time, but fortunately, mugwort is really the peak season of growth now, not to mention the mountains and wilderness, it can also be picked casually, I remember when I was a child, I washed my face with mugwort soaked in water every year during the Dragon Boat Festival, and I had to tie a red rope color thread on my hands, and I miss it very much.

Mugwort can repel mosquitoes, but it is a good thing, and after drying, it is made into aged mature mugwort, and when the time comes, after further processing to obtain moxa, you can add various medicinal materials to make moxibustion strips, and hang it on the skin to bake, in ancient times, this moxibustion method is called Taiyi Shen Needle, also known as Lei Huo Shen Needle, simply put, it is suspension moxibustion.

There are several different methods of moxibustion, such as direct moxibustion, warm moxibustion, interval moxibustion, etc., different symptoms are suitable for different methods, this kind of thing feels very mysterious, in fact, it is nothing more than the principle of heating, but there is no harm in proper use, but it cannot be used all the time, and the danger and harm are not small.

Yuan Shan took the mosquito coil bought from the mall back to the room, and said that the raw materials of realgar and mugwort are available, and tomorrow I will ask someone to prepare some preparations to make mosquito coils, and the effect does not know how, if it is really successful, then this is also a new product.
