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..."

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?
