Seeing that he really didn't understand it, the old man shook his head and looked at it suspiciously: "collecting medicine is the simplest part in refining medicine. According to the truth, as long as you study, you won't make such mistakes. Who is Xiaoyou's teacher? I didn't tell you that? "

"Teacher?" Su Yin scratched his head: "it's just an unknown little man!"

The name of the man who taught him pharmacology was Li Shigong. The name on the tombstone was "medicine saint". It was very strange at that time. He asked "cheap elder martial brother" specially and looked up a lot of information. In the whole mainland, there was no one with this name, let alone the title and occupation of medicine Saint Therefore, it is unnecessary to know that it was written by the posterity who erected the monument in order to compliment Hu.

What's more, if you are really a sage of medicine, will you not teach alchemy? Don't teach the method of curing disease and saving people, only teach the method of treating sow? In his opinion, even if this guy is proficient in pharmacology, he is a veterinarian at most. It's better not to say that he is shameful.

"That's right. The slightly famous pharmacist asked the younger generation to collect herbs. How could he not explain the rules?"

Shaking his head, the old man put his hands behind him, with the smell of teaching: "since you don't understand, I'll talk to you!"

"Yes Su Yin nodded with an open mind.

Seeing his appearance, the old man was very satisfied and said with a wisp of beard: "the roots of Hanyang grass grow in the cold and overcast place, but the flowers live in the hot sun. A medicinal plant combines the two properties of yin and Yang. Therefore, we must pay attention when picking, otherwise, once the root leaves the soil and the cold air has no source, the Yang attribute will take the upper hand and neutralize each other, which will lead to a sharp drop in the medicinal properties! "

Su Yin suddenly, at the same time with doubts: "since when the root leaves the ground, the two forces of cold and heat will blend, when picking, don't you just try to block it?"

"Ignorance!"

As soon as he threw his sleeve, the old man was displeased: "the nature of medicinal materials is ever-changing, including year, sunshine, nutrition, moisture Can have an impact on it, blocking the exchange of yin and Yang, said no problem, but I ask you, the drug is deep within the drug, do not pick down, how to clearly find the dividing line, make the best block? You know, if you don't succeed, you will destroy a medicinal plant, and all previous achievements will be wasted! "

"This..." Su Yin was stunned.

The two properties of yin and yang are so obvious that it should be easy to distinguish them even if they are hidden inside the medicinal materials!

In this way, the first assessment, he can be 100% correct, there will be no mistake, how to listen to each other's meaning, it is difficult?

"The correct way is to tie the red rope to the dividing line between sunshine and shadow when the Yang Qi is the strongest and Yin Qi is the weakest at noon, and cut it off at the red rope when the Yang Qi is the weakest at midnight."

The old man said: "in this way, the two attributes of yin and Yang will not blend, better to retain the two attributes!"

"What a trouble!" Unexpectedly, it took six hours to pick a medicinal plant. Su Yin shook his head and asked, "if you can find the intersection of yin and Yang and block it, is it OK to pick it directly?"

"That's the theory, but It's too hard! " The old man shook his head: "medicinal materials as a whole, the two properties of yin and yang are connected. How can we find them without cutting them! But once it is cut, it will destroy its medicinal properties and fall short of success. "

"No exaggeration

Shaking his head, Su Yin took a deep breath and sniffed: "the intersection of yin and Yang of this grass is here..."

Say, the finger stretched past, lightly a pinch, lift cold Yang grass to pull up.

"You..."

Did not expect to say so much, the young man, also direct medicine, the old man's face red, just want to scold a few words, suddenly pupil contraction, a face of can't believe.

"This How is that possible? "

Once the Yin and Yang meet, the flowers will lose their bright colors immediately. The red part will turn gray, and the white part will be slightly dim This young man, without looking at it, picked it at will. He thought that the flowers would decay immediately. He never dreamed that they were still very bright. It was no different from growing on the ground!

That is to say He not only found the right place to blend Yin and Yang, but also really blocked it!

How did you do that?

Even he, immersed in refining medicine for hundreds of years, can't finish it!

"It's very simple..." Seeing his fuss, Su Yin shook his head.

"Simple?"

The old man thought of something. He quickly put down the basket on his back, turned it over, and took out a green herb: "there is a nerve soothing drug in this herb. Can you find it?"

"This is tranquilizing herb. If you cut it off from this leaf, it can retain 70% of the medicinal properties of the whole plant!"

Su Yin drew a range on the leaf.

Suspicious, the old man took out the blade, cut the leaf according to the direction of the other side, and then chewed it in his mouth, his face turned pale immediately.

Exactly!

With the growth of plants, the medicinal properties are not evenly distributed, just like the contents of human body, fat and muscle.Because of this, even if we know that there is a slight deviation in the ratio of properties, the quality of pills will be affected, but No one can be sure, a medicinal material, in the end which position is more sufficient, and how much quantity it contains.

It's not 100 percent accurate.

But In front of him, the young man casually told us where the medicinal properties of this tranquilizing herb were concentrated, and even the quantity was exactly the same

That's a little scary! I can't believe what I saw with my own eyes.

"What about this one?"

She couldn't resist the excitement and took out several medicinal plants. Su Yin sniffed them gently and quickly explained in detail the properties, distribution and proportion of the drugs.

Cut up all the herbs and chew them carefully The old man soon found that the same and the other side said exactly!

In other words, the young man only looked at Without destroying the medicinal material itself, we can easily distinguish the number and distribution of medicinal properties!

"You..." Can't help it, the old man looked over with a little trembling: "are you born close to medicinal materials? Can you feel the distribution of drugs? "

It's said that some people are naturally sensitive to medicinal materials, and they can easily distinguish the properties that others can't tell. This one in front of us should not have this talent!

"Of course not..."

To his surprise, Su Yin shook his head: "there is no free lunch in the world. How can we get it for nothing without effort? What I can't tell at the beginning is that it took a lot of hard work to achieve this. "

"Hard work? That's right! No matter how talented you are, you certainly need to learn. "

The old man nodded with curiosity: "since you are young, from learning to easily distinguishing the distribution of drugs How long did it take? "

"My talent is average..." Recalling for a while, Su Yin's face showed bitterness: "about ten days!"

"Ten days?"

The old man stood still.

Ten years, are you sure?
