Ning Wuxian smiled bitterly: "Master Hua, it's not that I don't want to write, but that the tools required for that method are very special, and we can't make them here for the time being, you try the same juice extraction method, if it works, we will study the other method." ”

Artemisinin extraction requires a petri dish, and some proficient instrumentation.

According to Daxing's existing technology, it is difficult to achieve freedom of equipment, let alone extract artemisinin.

Extracting juice from Artemisia annua is as simple as soaking clothes in water and twisting the juice, and the only difficulty is.

"After the juice of this Artemisia annua is extracted, it also needs to be used with other drugs to achieve better results, and what kind of utensils is used to pack its juice so that it will not change, which needs to be studied by yourself."

He definitely didn't deliberately embarrass Hua Yi because Hua Yi only taught him the exercises and didn't teach him how to practice the Cloud Breath Gong.

At that time, he only knew the general direction of promoting medicine, not professional medical personnel, so he really didn't know the details of the arrangement.

"What kind of equipment should be used for artemisinin? This drug is beneficial to the people and the country, even if Jinling does not have it, the capital will definitely have it. ”

Don't look at Jinling's prosperous commerce, but most of the objects gathered are from the south to the north.

The capital that really connects goods farther away is the capital with the most convenient transportation.

The treasures of the countries in the Western Regions are all sent to various places for sale after being transferred through the capital, which is why even if some prefectures and counties are extremely wealthy, people still want to be Beijing officials.

In this era of centralized imperial power, the capital is a unique place where everything is integrated and the resources are given the highest priority.

"Sealed glass, clean hoses, and some minerals."

Ning Wuxian, who was too specific, didn't say anything.

Because the first one alone, the sealed glass, can stump Huayi.

Daxing has not yet mastered the method of refining glass, and the price of glass is more expensive than that of gold.

Whether you can buy sealed glass or not depends not on how much money you pay, but on whether the Western Regions country that makes the glass is willing to make it for you.

This kind of thing is the same throughout the ages.

"No wonder Ning Shixian refused to say that the method of extracting artemisinin turned out to be too difficult, I would venture to ask again, there are advantages and disadvantages between these two methods?"

"No, each has its own benefits, there is no superiority or disadvantage in any technology, just look at whether you use it to study and improve its function, what kind of medicine can exert the greatest effect of Artemisia annua juice, what kind of container should be used to keep it unchanged, and what kind of cloth can be used to better filter impurities, so as not to make the cost too high, these are all problems that you need to solve."

Ning Wuxian bowed his hand.

"I found a problem for the Chinese Normal School, and I worked hard for the Chinese Normal School."

This is indeed a big problem.

However, Hua Yi has encountered countless difficulties in his life, and when he is old, he can make achievements in Xinglin Medicine, and he is willing to accept this challenge.

"It's not hard, it's just a hard life, now find a few more life-saving medicinal materials, and the people of Daxing will reduce a little pain in the future."

Oh?

Ning Wuxian always felt that there was something in Hua Yi's words.

Before he could ask more, Hua Yi had already stuffed a stack of paper with the exercises written on it into his arms.

"After remembering it in my heart, I promised the master that I would never spread this exercise indiscriminately, in case people with improper mental skills get it, and there will be disputes in the world, Ning Shixian you...... If it weren't for the dedication of medicine, I would never have taught you Yun Xigong. ”

In other words.

In Hua Yi's eyes, Ning Wuxian is not a decent person.

Even teaching him this exercise, whether it will be spread out or not is a gamble.

Ruoning learned it without harm, and taught others what was discovered by Huayi......

"Ning Shixian, please swear with your life."

"Okay, I'd rather be safe and swear with my life, if there is no reply from the Chinese master and this exercise is leaked, this life will be disposed of by the Chinese master, and there will be no two words!"

People do not stand without faith, and industry does not prosper without faith.

This kind of simple and profound truth, Ning Wuxian has long been engraved in his heart.

In the face of the promises made by important people, he will definitely keep them.

Hua Yi saw that he didn't push back, or covered it up, he really took his promise to heart, and smiled with relief: "You kid still has advantages." ”

There are more than that, but there are too many advantages.

Ning Wuxian confidently straightened his waist, holding the pile of paper in one hand, and it was not convenient to flip through it in front of others.

Although Yun Fei was beside him, he couldn't let Yun Fei check it, and he was about to say it later, when Hua Yi had already turned around.

"I'll go to the kitchen and order someone to cook, you quickly write down the contents of the paper and burn it clean, and after dinner, we will go to the place where Artemisia annua grows to check."

I don't know if it's Ning Wuxian's illusion, Hua Yi's tone of voice doesn't seem to be as polite as before.

Never mind.

Anyway, he is also half of his master.

Ning Wuxian didn't care about this kind of detail anymore, bowed towards the background of Hua Yi's departure, walked into the room with the paper, and explained to Yun Fei that he would look at the door and not let anyone in.

So he put the wad of paper on the table and stretched it out.

Above are seven portraits of meditation and practice, seven mantras, as well as Hua Yi's personal comments on his feelings.

"The subtlety of the exercises of Yun Xi Gong is not to strengthen the body and enhance the force, but to weaken oneself and reduce one's strength...... is worthy of being a master in the direction of metaphysics, and this commentary is quite mysterious. ”

Looking at the application and introduction of each layer of exercises, Ning Wuxian summarized the purpose of cultivating Yunxi Gong in one sentence.

That is to use the method of breathing, breathing introverted, reducing the sense of existence, and then using ingenuity to resolve the crisis after the enemy is careless.

The internal strength is real, but the use is skillful, four or two dials a thousand catties.

"Don't clash head-on with people, the main thing is to be ruthless, and the person who created this exercise is quite lazy."

This kind of exercise, which has a certain degree of inertia, is really suitable for him.

Ning Wuxian concentrated, memorized the content on the paper in his mind, and engraved it into his heart, although he hung one arm and couldn't devote himself to it, but fortunately, this exercise had almost no requirements for the physical fitness of the beginner, as long as the breath could work.

After memorizing all the exercises on the seventh floor, he directly lit a pile of paper on the table according to the agreement, threw it into the copper basin with ice and burned it clean.

While the meal was still open outside, he sat cross-legged on the couch and, according to the mantra, began to try to cultivate the first layer of the introductory Cloud Breath Gong.

"Heaven and earth are natural, and qi follows the shape and gathers in the cage."

"Hold your breath for five moments and enter the spring, and then reunite with Guan Yuansheng Baihui."

According to the explanation in the annotation, Ning Wuxian pressed his tongue against the upper chamber, and when his mouth was full of words, he held his breath and counted five, and as he silently recited the mantra in his heart, he could faintly feel that there was a stream of gas gushing from the bottom of his feet, all the way to the Guan Yuan point in the abdomen, that is, near the dantian, and finally swirled directly along the throat at the base of the tongue and rushed to the top of his head.

While refreshing the mind, as if the body switch has been turned on, an invisible air flow gathers, making the body feel much refreshed.

This cycle repeats, inhaling deeply and holding your breath, so that the gas is familiar with the transfer from the body, and then slowly overflows from the body.
