Seeing that he really didn't understand, the old man shook his head and looked over in confusion: "Collection of herbs is the simplest part of refining medicine. According to the principle, as long as you study, you will not make such mistakes. I wonder who my friend's teacher is? I didn't tell these things?"

"Teacher?" Su Yin scratched his head: "Just an unknown little person!"

The residual pharmacological idea was taught by Li Shihua. The name marked on the tombstone was "Medical Saint". It was strange at that time. I specifically asked "Brief Brother" and also looked up a lot of information. There was no one in the whole continent who called this name, and there was no title or profession of the Medicine Saint... So, you don't have to think about it and you know that it was a descendant of the monument, which was written in order to compliment.

Besides, if the saint of Medicine is really the case, would he not teach elixir? He would not teach curing diseases and saving people, but only teach how to treat sows? In his opinion, even if this guy is proficient in pharmacology, he is at most a veterinarian. Instead of saying it, it would be better not to say it.

"That's right, a slightly famous alchemist, if you ask the younger generation to collect herbs, how could you not explain 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 a humble look on his face.

Seeing his appearance, the old man was very satisfied and said with his beard: "Cold Yang grass, roots grow in the yin and cold place, but the flowers live in the yang. A medicinal material combines the two attributes of yin and yang. Therefore, you must pay attention when picking, otherwise, once the roots leave the soil and the cold air loses its source, the yang attributes will gain the upper hand and neutralize them in pairs, resulting in a sharp drop in medicinal properties!"

Su Yin suddenly realized, and at the same time he was puzzled: "Since the roots are left to the ground, the two forces of cold and heat will blend together. When picking, can you just find a way to block them?"

"ignorance!"

When the old man shook his sleeves, he looked unhappy: "The medicinal properties of medicinal materials are ever-changing. Years, sunshine, nutrition, and moisture... can all affect them and block the exchange of yin and yang. There is no problem, but I ask you, the medicinal properties are hidden deep within the medicine. If you don't pick them, how can you clearly find the dividing line and make the best block? You must know that if you fail, it is equivalent to destroying a medicinal material and all your previous efforts are wasted!"

"This..." Su Yin was stunned.

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

During the first assessment, he can achieve 100% correctness without any mistakes. How can he listen to the other party’s meaning?

"The correct way is to wait here until noon, when the yang energy is the most strong and the yin energy is the weakest, tie the red rope to the sunlight and shadow dividing line of the medicinal material. When the yang energy is the most weak, cut it at the red rope!"

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 a full 6 hours to pick a medicinal plant. Su Yin shook his head and asked, "If you can find the intersection of yin and yang, block it, and pick it directly, is it okay?"

"This theory is like this, 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 it be found without being cut open? Once cut open, the medicinal properties are destroyed and the effort is in vain..."

"It's not that exaggerating!"

Shaking his head, Su Yin took a deep breath and sniffed it with his nose: "The intersection of yin and yang of this grass is here..."

As he said that, he stretched out his fingers, pinched them gently, and pulled them up with Hanyang grass.

"you……"

Unexpectedly, after saying so much, the young man took medicine directly. The old man's face turned red with anger. He was about to scold him, but his pupils suddenly contracted, and he looked unbelievable.

"How is this... possible?"

The cold yang grass, once the yin and yang meet, the flowers will immediately lose their bright colors, and the red areas will turn gray and white areas will be slightly dim... This young man didn't even look at it and picked it casually. He thought the flowers would immediately decline, but he didn't even think about it. He was still extremely bright and 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 did it be done?

Even if he has been immersed in refining medicine for hundreds of years, he can't complete it!

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

"Simple?"

The blue veins on his forehead were leaping. The old man thought of something and hurriedly put down his backpack, flipped it out, and took out a green medicinal plant: "There is a medicinal plant that contains the medicinal properties that soothes the nerves. Can you find it?"

"This is the Anshen Grass. If you cut it from here on this leaf, it can retain 70% of the medicinal properties of the entire medicinal herb!"

Su Yin casually drew a range on the leaves.

As he was skeptical, the old man took out the blade and cut the leaf down according to the direction the other party explained, then put it in his mouth and chewed it, and his face turned pale immediately.

Not bad at all!

The medicinal properties of medicinal materials are not uniformly distributed with plant growth, just like the content of fat and muscles of the human body is also uneven.

Because of this, even if you know that the slightest deviation in the ratio of medicine properties will affect the quality of the elixir, no one can determine which position a medicinal material has more medicinal properties and how many quantities it contains.

Not 100% accurate.

But... the young man in front of him casually said that the medicinal properties of this Anshen herb are concentrated, and even the number is not bad...

This is a bit terrible! I can’t believe what I saw with my own eyes.

"Where is this plant?"

Resisting the excitement, he took out a few more medicinal herbs, and Su Yin sniffed it gently, and quickly explained the medicinal properties, where the drug was distributed, and how much it accounted for.

Cut all the medicinal materials mentioned by the other party and chew them carefully... The old man soon found that it was exactly the same as what the other party said!

In other words, the boy only took a look... without destroying the medicinal materials themselves, he could easily distinguish the properties and distribution of the medicinal properties!

"You..." I couldn't help it anymore, and the old man looked over with a trembling trembling: "Are you born to be close to medicinal materials? Can you feel the distribution of medicinal properties?"

Legend has it that some people are naturally sensitive to medicinal materials and can easily distinguish the medicinal properties that others cannot tell. The person in front of them should have such talent!

"Of course not..."

Unexpectedly, he would think like this. Su Yin shook his head: "There is no free lunch in the world. How can I get it in vain without hard work? I couldn't tell at the beginning, and it took hard work to achieve this."

"Work hard? That's right! No matter how talented you are, you must learn."

The old man nodded with curiosity in his eyes: "It depends on your age. How long has it been taken from starting to learning to easily distinguishing the distribution of the medicinal properties?"

"I'm just as talented..." After recalling, Su Yin's face showed bitterness: "It's about ten days!"

"Ten days?"

The old man suddenly stiffened and stood there.

Are you sure you are right, it's not ten years?
