"I have seen Mr. Tie in my humble position." Wan Lei bowed deeply in a formal manner. Because the person sitting in the middle hall was Shuntian Fu Yin, a third-grade senior official, Wan Lei could only look up. Fortunately, this was not a formal occasion. If it was in the court,
When they meet in person, he has to kneel down and kowtow.
"You have been assigned to Changping Post. The post is well organized and you get along well with the villagers. You can be regarded as a good official." Tiefu Yin looks like he is in his thirties. His face and eyes look a bit weird, and you can't look at them no matter what.
He looks too much like an orthodox Han Chinese. However, at such a young age, he is a third-rank official, so he really cannot be judged by his appearance.
"Your Excellency, you are ridiculously complimenting me. I am ashamed of my humble position." Wan Lei still had a frightened expression on his face, but his heart was bright: the so-called "I don't go to the Three Treasures Hall for anything", this Master Tie must have something to ask for, otherwise he would not come in person.
Come on, let alone praise me as soon as you meet me.
In fact, this guy took office in Shandong Province years ago and was responsible for raising military rations for the Ping Yan Army. After the Yan rebels were eliminated, he was promoted to the first Shuntian Governor for his merits, and he is still in charge of military ration supplies for the Northern Expedition. The governor of a palace has a busy schedule.
Going to the door in person is definitely not just coming to inspect the work.
As for what it was for, it goes without saying. As soon as Wan Lei saw that in addition to a master standing next to him, there was also a kind-faced old woman. Without asking, he knew that he was here to seek medicine. As for who it was for.
Asking for medicine is unknown, but one thing is certain, that person is his beloved, otherwise he would not come in person.
"I heard from someone that you have a secret recipe handed down from your ancestors that can make your face whiter and more beautiful. Can you take this seriously?" As Wan Lei expected, he went straight to the topic.
"Generally speaking, it is possible, but it cannot be a cure-all. There are some special circumstances where it is useless."
“Can freckles be cured?”
"It depends on the situation. There are many causes of freckles. Using different formulas according to different causes and paying proper attention to diet and maintenance can generally reduce the symptoms, but it is difficult to cure them." Wan Lei said.
The so-called freckles are actually freckles, a kind of dark brown spots that appear on the face and other places and are scattered on the face. In fact, human skin originally has small breasts that produce melanin, and they continuously produce melanin to resist the harmful effects of the universe.
Various harmful rays are harmful to the human body, especially ultraviolet rays. Due to the difference in melanin contained in the skin, humans are divided into three types: black, yellow and white.
Freckles are caused by a genetic mutation. Of course, this is not a disease. It has no impact other than affecting the appearance. Westerners even regard a sparrow face as a symbol of maturity and sexiness, while people from the Central Plains think that a face with freckles is a symbol of maturity and sexiness.
It is a manifestation of blood deficiency and qi stagnation, which not only affects vision, but is also a symptom of physical illness.
"Go and invite the young master in." Tie Xuan ordered, and the old lady quickly walked out of the hall and helped out from the official sedan a young man in rich clothes who lowered his head and did not dare to see anyone.
Wan Lei was also surprised. He thought he was a young lady who loves beauty, but he didn't expect it to be a young master. And the average man has a few freckles that don't affect his appearance and won't mind him. This little guy lowered his head and didn't dare to see him.
Man, the problem must be serious.
As Wan Lei expected, he just glanced at the young man's face and almost screamed, because this guy's face was covered with dense black freckles, which was in sharp contrast to his white face.
, the whole face is like a chessboard, black and white, so shocking.
Seeing Wan Lei's expression change, Tie Xuan waved his hand and asked the mother to take his son away, and then asked: "Can it be cured?"
"It may be curable, but I lack a medicine on hand. Without this medicine, this disease cannot be cured. Of course, other methods can be used to relieve symptoms, such as going out less often, washing your face with rice water, and paying more attention.
rest..."
"What medicine is missing?"
"A very special mineral, even adults don't know about it." Wan Lei shook his head. In fact, he had already seen that if the young man's freckles do not continue to worsen, he must always use sunscreen to block them.
Light, especially ultraviolet radiation.
There are many types of sunscreen, which are mainly divided into physical sunscreen and chemical sunscreen. Chemical sunscreen uses the characteristics of certain organic substances to absorb ultraviolet rays. However, these organic substances are difficult to produce and cannot be produced with the current technical level; as for physical sunscreen
, which is to use certain inorganic substances with the function of reflecting light to block ultraviolet rays from the skin. The most commonly used one is zinc oxide.
Zinc oxide, commonly known as zinc white, is not difficult to produce. As long as you can find sphalerite (the main component is zinc sulfide) and calcine it in the air, the resulting powder is zinc oxide. However, the difficulty lies in how to find sphalerite.
.
Ordinarily, the Central Plains is rich in various mineral deposits, but now the mining industry is underdeveloped. The main minerals are gold, silver, copper, iron and tin. Even if people see sphalerite, they will only regard it as useless stone. If he goes to find it by himself,
But it's like finding a needle in a haystack.
If zinc blende cannot be found, zinc white cannot be produced, and it cannot be added to facial cream to make sunscreen. However, Tie Xuan did not understand this causal relationship. He glanced at Wan Lei and said:
"Just tell me what you're missing, and I'll do my best to get it for you."
Obviously, he regarded Wan Lei as a villain who took the opportunity to knock bamboo poles.
"Zinc sphalerite is a mineral that can turn into white powder when calcined in the air. If you, sir, can find it, then I can guarantee that I can make a useful facial cream. If not, then I apologize for my incompetence."
"Sphalerite? What is it?" Tie Xuan looked at the master standing beside him. The master also shook his head. Naturally, he had never heard of this term.
Wan Lei thought for a while and then asked: "Where can we produce lead in Ming Dynasty?"
The metal zinc was discovered relatively late, so it is normal for the world not to know about it. However, the metal lead was discovered thousands of years ago and was widely used at this time. The main mineral of lead is galena, which is sulfide.
Lead. Wan Lei remembered that galena often coexists with sphalerite. As long as galena is found, it is possible to find sphalerite.
"Lead? It is produced in many places in Ming Dynasty, especially in Huguang, Yunnan and other places, where there is a lot of production." Master said.
"That's good. Let's go to the mining area and bring back some raw ore. Remember, it's raw ore, just the kind without mud."
"How much do you need?" Tie Xuan asked.
"It's a humble job but I don't know, the more the better."
"Can we not use lead ore for this?" Tie Xuan hesitated. He knew that the lead mines were run by the imperial government, because lead contained silver, and the imperial court expected to use them to extract silver. If he wanted to get these raw ores, he had to
You can't go through the back door. If it's just a few pieces of ore, then that's it. You can just bribe a miner to bring it out. It's not a big deal. If it's hundreds or thousands of kilograms, then it's a big problem. You might have to impeach the imperial envoy.
"That's enough for my humble words. As for how to get the minerals, please decide for yourself." Wan Lei bowed his hand and said no more, but he said in his heart: "I want my son to be good, but I don't want to spend money to provide things, so I am empty-handed."
Even if you come here, you don’t even want to provide the necessary things. You are really a tough guy."
