Seeing that he really didn\'t understand, the old man shook his head and looked at it suspiciously: "collecting medicine is the simplest part of refining medicine. According to the truth, as long as you study, you won\'t make such a mistake. I don\'t know who Xiaoyou\'s teacher is? I didn\'t tell you these things?"

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

The remnant who taught him pharmacology was called Li shiye. The name marked on the tombstone was "medicine saint". At that time, it was very strange. I specifically asked "cheap elder martial brother" and checked a lot of information. There was no person named this name in the whole mainland, let alone the title and occupation of medicine Saint... Therefore, it is needless to think that it was written by the descendants of the monument in order to compliment Hu.

Besides, if you are really a medicine sage, will you not teach alchemy? Do not teach the method of curing the disease and saving people, but only the method of treating sows? In his opinion, even if this guy is proficient in pharmacology, he is at most a veterinarian. It\'s better not to say it than to be ashamed.

"That\'s right. A little famous herbalist asked his younger generation to collect medicine. How can he not tell the rules!"

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

"Yes!" Su Yin nodded with an open face.

Seeing his appearance, the old man was very satisfied and said with a wisp of beard: "cold Yang grass, the roots grow in the cold place, but the flowers live in the hot sun. A medicinal plant integrates the two attributes of yin and Yang. Therefore, we must pay attention to picking. Otherwise, once the roots leave the soil and the cold air has no source, the Yang attribute will prevail and neutralize the two, resulting in a sharp drop in drug properties!"

Su Yin suddenly wondered, "since the two forces of cold and heat will blend when the roots leave the ground, can\'t you just find a way to block them when picking?"

"Ignorance!"

The old man looked unhappy when he threw his sleeves: "The medicinal properties of medicinal materials are ever-changing. The year, sunshine, nutrition and moisture can all affect them. It\'s no problem to block the communication between yin and Yang. But I ask you, how can you clearly find the dividing line and make the best blocking if the medicinal properties are hidden in the drugs and not picked? You know, if you don\'t succeed, you\'ll destroy a medicinal material and lose all your previous achievements!"

"This......" Su Yin was stunned.

The two attributes of yin and yang are so obvious that it should be easy to distinguish even if they are hidden in the medicine!

In this way, he can be 100% correct at the first assessment without any mistakes. How can he listen to the other party\'s meaning? It\'s difficult?

"The correct way is to wait here until noon, when Yang is the most prosperous and Yin is the weakest, tie the red rope on the dividing line between sunshine and shadow of the medicinal materials, and cut it off at the red rope when Zi Shi and yang are the weakest!"

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

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

"That\'s the theory, but... It\'s too difficult!" the old man shook his head: "as a whole, the two attributes of yin and yang are connected. How can we find them without cutting! Once cut, it will destroy the drug properties and fall short..."

"Not so exaggerated!"

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

With that, he stretched out his finger, pinched it gently, pulled up the cold Yang grass.

"You..."

Unexpectedly, after saying so much, the young man also directly collected medicine. The old man\'s face turned red and wanted to scold. Suddenly, his pupils contracted and he couldn\'t believe it.

"How is this... Possible?"

Cold Yang grass, once Yin and Yang meet, the flowers will immediately lose their bright colors. The fiery red places will become gray, and the white places will be slightly dim... The boy didn\'t look at it and picked it casually. He thought the flowers would decay immediately. He didn\'t think about it in his dream. It is still very bright, which is no different from growing on the ground!

In other words... He not only found the right place where Yin and Yang blend, but also really blocked it!

How?

Even if he was immersed in refining medicine for hundreds of years, he couldn\'t finish it!

"It\'s very simple..." seeing his fuss, Su Yin shook her head.

"Simple?"

The green veins on his forehead jumped disorderly. The old man thought of something. He quickly put down the basket on his back, turned it over, and took out a green medicinal material: "there is a drug that can relieve the nerves in this medicinal material. Can you find it?"

"This is tranquilizer. If you cut off this leaf from here, you can retain 70% of the medicine of the whole plant!"

Su Yin drew a range on the leaves.

Skeptical, the old man took out the blade, cut the leaf according to the direction given by the other party, and then chewed it in his mouth. His face immediately turned white.

perfectness!

The medicinal properties of medicinal materials are unevenly distributed with the growth of plants, just as the contents of human body, fat and muscle are equally unequal.

For this reason, when refining pills, even if you know that there is a slight deviation in the ratio of drug properties, it will affect the quality of pills, but... No one can determine which position of a medicinal material has more drug properties and how much it contains.

Not 100% accurate.

But... The young man in front of him casually said the place where the medicinal properties of this tranquilizer grass were concentrated, and even the number was exactly the same

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

"What about this one?"

He couldn\'t help but get excited and took out a few more herbs. Su Yin sniffed them gently and soon explained in detail the properties, distribution and proportion of the drugs.

Cut up all the herbs the other party said and chew them carefully... The old man soon found that they were the same as what the other party said!

In other words, the boy only took a look... Without destroying the medicine itself, he can easily distinguish the amount and distribution of the medicine!

"You..." the old man looked at it with a little trembling: "are you naturally close to medicinal herbs? Can you feel the distribution of medicinal herbs?"

It is said that some people are naturally sensitive to medicinal herbs. They can easily distinguish the medicinal properties that others can\'t distinguish. This one in front of us should not have this talent!

"Of course not..."

Unexpectedly, Su Yin shook her head. "There is no free lunch in the world. How can I get it in vain without hard work? I couldn\'t tell it at the beginning. It took hard work to do this."

"Work hard? That\'s right! No matter how talented you are, you certainly need to learn."

With a frozen look, the old man nodded with curiosity in his eyes: "look, you\'re not old. How long did it take to learn and easily distinguish the distribution of drug properties

"My talent is average..." after recalling, Su Yin\'s face showed bitterness: "about ten days!"

"Ten days?"

The old man stood still.

Are you sure you\'re right, not ten years?
