Seeing that he really didn't understand, the old man shook his head and looked at him suspiciously: "Collecting medicine is the simplest part of alchemy, according to reason, as long as you study, you won't make this kind of mistake, I don't know who Xiaoyou's teacher is?

"Teacher?" Su Yin scratched his head: "It's just a little-known little person!"

The remnants of teaching him pharmacology are called Li Shijing, and the name marked on the tombstone is "Medicine Saint", which was very strange at the time, and he specifically asked "Cheap Senior Brother", and also checked a lot of information, and in the whole continent, there is no person with this name, let alone the title and occupation of Medicine Saint...... Therefore, you don't have to think about it to know that it is the descendants of the monument, in order to compliment Hu wrote.

Besides, if it is really a medicine saint, will he not teach alchemy? will not teach the method of curing diseases and saving people, but only teach the method of treating sows? In his opinion, even if this guy is proficient in pharmacology, he is at most a veterinarian, and it is better not to say it than to say it is embarrassing.

"That's right, a slightly famous alchemist, let the juniors collect medicine, how can you not talk about the rules!"

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

"Yes!" Su Yin nodded, looking humble.

Seeing his appearance, the old man was very satisfied, and said with his beard: "Cold Yang Grass, the roots grow in a cold place, but the flowers live in the scorching sun, a medicinal herb, integrating the two attributes of yin and yang. Therefore, you must pay attention when picking, otherwise, once the roots leave the soil, the cold will have no source, and the yang attribute will take over, and the two will be neutralized, which will lead to a sharp drop in medicinal properties!"

Su Yin was stunned, and at the same time with doubts: "Since when the roots are off the ground, the two forces of cold and heat will blend, and when picking, can't you just find a way to block it?"

"Ignorance!"

Flicking his sleeves, the old man was displeased: "The medicinal properties of medicinal materials are ever-changing, such as vintage, sunshine, nutrition, and moisture...... can have an impact on it, blocking the communication between yin and yang, there is no problem, but I ask you, the medicinal properties are deep in the medicine, if you don't pick it, how to clearly find the dividing line, make the best block?

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

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

This method, when he is assessed for the first time, he can be 100% correct, and there will be no mistakes, how to listen to the other party, it is difficult?

"The correct way is to wait here until noon, when the yang energy is the strongest and the yin energy is the weakest, tie the red rope to the dividing line between the sunlight and shadow of the medicinal herbs, and when the child is the weakest, cut it off at the red rope!"

The old man said: "In this way, the two attributes of yin and yang will not blend, and it is better to retain the two attributes!"

"It's so troublesome!" Unexpectedly, it would take 6 hours to pick a medicinal herb, Su Yin shook his head and asked, "If you can find the intersection of yin and yang, block it, and pick it directly, it's okay, right?"

"The theory is so, but ...... It's too difficult!" The old man shook his head: "The medicinal herb as a whole, the two attributes of yin and yang are connected, how can it be found without cutting it......!

"It's not that exaggerated!"

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

As he spoke, he stretched out his fingers, pinched them gently, and pulled them up while holding the cold sun grass.

"You ......"

I didn't expect to say so much, this young man, and directly collected medicine, the old man's face turned red, and he was about to scold a few words, when his pupils suddenly contracted, and he couldn't believe it.

"This ...... How is that possible?"

Once the yin and yang meet, the flowers will immediately lose their bright color, and the fiery red places will become gray, and the white places will be slightly dull...... This young man, without even looking at it, picked it with his hands, thought that the flowers would decay immediately, but he didn't even dream about it, it was still extremely bright, no different from growing on the ground!

Other words...... Not only did he find the right place where yin and yang blended, but he really blocked it!

How?

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

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

"Simple?"

The green tendons on his forehead were jumping, the old man thought of something, hurriedly put down the back basket on his body, turned it over, and took out a turquoise medicinal herb: "Among this medicinal herbs, there is a medicinal property that soothes the nerves, can you find out?"

"This is the Tranquilizing Herb, on this leaf, if you cut it off from here, you can retain 70% of the medicinal properties of the entire medicinal herb!"

Su Yin casually drew a range on the leaves.

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

Without the slightest error!

The medicinal properties of the herbs, along with the growth of the plant, are not evenly distributed, just as the content of the human body, fat and muscle is also uneven.

Because of this, when refining the pill, even if you know that the slightest deviation in the ratio of medicinal properties will affect the quality of the pill, but ...... No one can determine which position of a medicinal herb is more medicinal and how much it contains.

It's not 100% accurate.

Can...... The young man in front of him casually said the place where the medicinal properties of this tranquilizing herb were concentrated, and even the quantity was exactly the same......

It's a little scary! I can't believe it when I see it with my own eyes.

"Where's this one?"

Holding back his excitement, he took out a few more medicinal herbs, Su Yin sniffed lightly, and quickly explained in detail the medicinal properties in the medicine, where it was distributed, and how much it accounted for.

Chop up all the herbs that the other party said and chew them carefully...... The old man soon found out that he was exactly what the other party said!

That is, the teenager only glanced at it...... Without destroying the herb itself, you can easily distinguish the amount and distribution of medicinal properties!

"You ......" couldn't help it anymore, and the old man looked at it with a slight tremble: "Are you born with an affinity for medicinal herbs?

Legend has it that some people are naturally sensitive to medicinal materials, and he can easily distinguish the medicinal properties that others can't distinguish.

"Of course not......"

I didn't expect him to think like this, Su Yin shook his head: "There is no free lunch in the world, how can you have the ability to get it for nothing without hard work?" I couldn't tell it at first, and it took hard work to do this. ”

No matter how talented you are, you definitely need to learn. ”

With a condensed expression, the old man nodded, with curiosity in his eyes: "Seeing that you are not very old, from the beginning of learning, to the distribution of medicinal properties can be easily distinguished...... How long did it take?"

"I'm ...... average talent" recalled, Su Yin's face showed bitterness: "About ten days!"

"Ten days?"

The old man stiffened in place.

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