For the few apprentices in the medicine hall, the most disliked thing is probably this matter of sorting medicinal materials.

After all, there are many kinds of medicinal materials, and a considerable part of them are not much different in appearance, and there are even many similar ones.

The subtle differences in appearance, medicinal properties, are worlds apart.

If there is a slight mistake, it must be a reprimand or even punishment from Elder Li!

But for Chu Mu, this kind of thing that can perfectly combine theory and practice, he is naturally happy with it.

After all, a few bags of medicinal materials, if he buys them by himself, even if he only buys a small amount of each medicinal material, the accumulation is a sky-high price.

In his ruined guest room medicine cabinet, there were only a few dozen common medicinal herbs, and the amount was very small, but it also cost him nearly two months of black gold and moon.

Right now, this kind of "public fat for private interests", how could Chu Mu not be happy.

Choosing a piece of medicinal herbs, Chu Mu's expression was as focused as ever, and from time to time he pinched a piece of medicinal herbs and put them in his mouth to chew, while experiencing the medicinal properties of the medicinal materials, he corresponded to the medical book knowledge in his mind.

Li Lao leaned back on the recliner, his eyes narrowed slightly and looked at Chu Mu, his face groaning, as if he was thinking about something.

Chu Mu was immersed in it, and it seemed that he had completely ignored the outside world.

Time passed, and it wasn't until a few sacks of medicinal materials were selected that Chu Mu came back to his senses.

Recalling the selection process just now, Chu Mu also sorted out his harvest bit by bit.

People are self-aware.

Chu Mu knew very well that without using the "Spiritual Blessing", he was no different from ordinary people.

At most, it is the insight of his previous life, which makes him probably a little more learning than ordinary people in this era.

If you learn from the past, learn from the past, and gain from it, you have to consolidate it over and over again and absorb it thoroughly.

If not, in a few days, you will forget about it, which is equivalent to a waste of effort.

"There are also medicinal herbs in that wooden box, you can also go and sort them."

Li Lao pointed to a wooden box on the side and said leisurely.

"Okay."

Chu Mu nodded, stepped forward quickly, the wooden box was opened, and Chu Mu couldn't help but be stunned.

The wooden box is not big, and the box is unremarkable, but inside the box, it is not as Chu Mu expected, it is piled up with medicinal materials, but neatly placed wooden boxes.

Compared with the ordinariness of the wooden box, the neatly stacked wooden box in this box is obviously much more exquisite.

The color of the wood is pale red, but it is not the red of the paint, but the color of the log, and the wooden box is carved with different exquisite patterns.

Just these wooden boxes are probably worth a lot of money.

"Herbs?"

Chu Mu pursed his lips, picked up a wooden box with some suspicion, opened the lid of the box, and a herb came into view.

"Prunella vulgaris, bitter and astringent in taste, medicinal and cold......"

Subconsciously, Chu Mu's mind poured out all kinds of memories about this medicinal herb.

It is a very ordinary medicinal material, which can be found almost everywhere in the vicinity where Nanshan Town is located, and it is also a very small number of medicinal materials that can be easily purchased with Chu Mu's own financial resources.

Such an ordinary medicinal herb is packaged in such a delicate wooden box......

Chu Mu was a little speechless, with the ordinary and cheap prunella grass, just this wooden box, it is estimated that he can buy a lot of it.

Just as Chu Mu was about to take out the prunella grass in the wooden box and classify it according to the previous process, Chu Mu's outstretched hand was suddenly stunned.

Wrong......

Chu Mu stared at the prunella grass in front of him.

He was very sure that the medicinal herb in front of him was undoubtedly Prunella vulgaris!

But......

"This grass is born in Pingze, the leaves are like swirling, the first spring is born, the spike is out in April, its flowers are purple and white, like salvia flowers, there are everywhere, grow for a year, the leaves are purple and white, grow for ten years, the white lines are dull, it is difficult to discern ......"

All kinds of memories about this summer withered grass also came to my heart at this moment.

No matter what kind of herb, nature has its growth law, flowering and fruiting, growth and withering, this is an inevitable process.

This was true in previous lives, and it is also true in this era.

But the only difference is that the plants of this era have a much stronger ability to survive than in previous lives.

Just like this prunella grass, there is no difference between this prunella grass and the Chinese medicine prunella grass in the previous life.

However, in the previous life, the grass was as its name suggested, and the white flowers were withered, so it was called Prunella.

The prunella grass of this era is also a white flower summer wilt, but this wilting will only wither part of it, and the remaining part will grow against its growth cycle.

One year, two years, three years......

According to the description in the medical book, not only Prunella vulgaris, but also most other medicinal herbs and plants have this phenomenon of violating the growth cycle.

Of course, the medicinal properties of this kind of medicinal herb that transcends its own growth cycle will naturally change with its year.

The longer the vintage, the more precious it is!

How many years can it grow up to at most, Chu Mu didn't know, because those medical books didn't describe this.

But this Prunella vulgaris, according to the herbal illustrated book given by Li Lao, the description of the year identification of Prunella vulgaris is the largest, which is the description of Prunella vulgaris up to 200 years.

There is a saying in the book: two hundred years, the rhizome is straight around the week, nine or ten inches long, the leaves become twins, the leaves are dark red, and the veins are green......

And the strain in his hand, Chu Mu carefully discerned, limited knowledge corresponds to infinite possibilities.

A slightly vague answer also emerged in Chu Mu's heart.

"Fifty...... Sixty years or so......"

In other words, what he thought was ordinary Prunella was actually a treasure that was fifty or sixty years old!

Chu Mu's breathing was a little short, and his eyes instantly fixed on the wooden box in front of him, the delicate wooden boxes were neatly placed, with the size of this wooden box, there were at least twenty or thirty wooden boxes in front of him!

Chu Mu carefully put the fifty or sixty-year-old prunella grass in his hand back into the wooden box, and his movements were unprecedentedly slight, for fear that the strength would be too great and damage the slightest.

When the wooden box was covered, Chu Mu couldn't wait to pick up the other wooden box in the wooden box.

The wooden box opened, and a medicinal herb that also seemed ordinary came into view.

With the lesson of Prunella vulgaris, Chu Mu naturally would no longer despise the slightest, and under careful discernment, a plant that was about twenty years old, and Banxia, which originally only existed on books, had also witnessed it again and again.

One by one, the wooden boxes were opened and carefully closed.

The medicinal herbs were held in his hands, and the contents of the medical books were also unprecedentedly crazy in Chu Mu's mind, combining them with the reality in front of him little by little.

Ten years, twenty years, thirty years......

A seemingly ordinary herb has no obvious change in the herb itself under the difference in years.

Exhausted what you have learned, exhausted your focus, and treated this extremely rare experience......
