Longevity starts with learning

At dusk, the billowing black smoke had not yet stopped, and the entire sky was shrouded in a shadow under the rising black smoke.

In the town, the blood-stained courtyard door slowly opened, and Chu Mu walked out. Just like the sky, there was also a layer of haze between Chu Mu's eyebrows.

Chu Mu had already turned a blind eye to the suffering of others. It took him nearly a quarter of an hour to walk to Mingxin Hall, which was only a few hundred meters away.

"Mr. Li."

As usual, Chu Mu bowed respectfully.

"I'm here."

Mr. Li put down the book in his hand and looked at Chu Mu who was standing with his head bowed. Then his slightly turbid eyes moved and looked outside the door.

There were few people on the street. Apart from the busy inspections, there were only the corvées who were taken back by the captives.

At this moment, a team of escaped corvées were being escorted by the inspectors outside the door. They were scolded and scolded. Many inspectors' sabers were covered with blood.

After a while, Mr. Li said faintly: "I just saw you go to the mountain... What's the situation in the mountain?"

Chu Mu organized his words. Except for his uncertain guess, he did not hide all the other discoveries, including the "spiritual mine" in the mine and the remarks of the man in white.

"Next month at the beginning of the month..."

Mr. Li's eyes moved slightly, and his eyes looking at Chu Mu seemed to have a little more strange color.

"Since Brother Mu has embarked on the path of cultivation, it is better to participate less in worldly affairs. You should concentrate on cultivation and strive to embark on the path of immortality as soon as possible."

"Mu... understand."

Chu Mu's heart trembled, and he responded quickly.

Mr. Li nodded, picked up the book in his hand again, but did not say anything.

Chu Mu was silent for a moment, but he didn't ask any more questions. He walked to the counter and handed the handwritten list of medicinal materials to the apprentice behind the counter.

"Brother Mu, do you want it now?"

"Yes."

Chu Mu nodded: "Please prepare it for me. I want it now."

"The quantity is a bit large. Brother Mu, please wait a moment. I'll go to the warehouse to check."

The apprentice took the list and walked away quickly.

Chu Mu stood in front of the counter with a calm expression, but his mind was already surging with thoughts.

He was thinking, what did Mr. Li's words just now imply? Or was it just a casual remark?

Chu Mu was not sure, but he didn't like this feeling.

It was like drifting with the flow, the waves were so turbulent that he couldn't control them at all. Whether he wanted to or not, he seemed to be swept away by the turbulent waves.

It has always been like this since he came to this world, and it seems to be the same now.

...

When the night fell, Chu Mu walked out of Mingxin Hall with several large bags of medicinal materials.

The candles at home were lit, and under the flickering firelight, Chu Mu carefully sorted out the large bags of medicinal materials.

The medicinal materials were expensive, but not precious. They were all medicinal materials within their own growth cycle. As for the medicinal materials that exceeded their growth cycle... Chu Mu couldn't buy them even if he wanted to.

The source of Mingxintang's medicinal materials was either the herbalists in the surrounding villages and towns, or several medicinal material shops in the county.

Chu Mu had already found out that medicinal materials that exceeded their own growth period were not allowed to be sold according to the laws of the Great Chu. If they were found, they must be handed over, otherwise, it would be a serious crime punishable by beheading.

Of course, this was obviously a law for ordinary people. People like Li Lao obviously would not take the secular laws in their eyes.

But at the moment, Chu Mu could obviously contact most ordinary people. Could he buy medicine from immortal cultivators?

After counting and sorting them into medicine cabinets, Chu Mu walked to the wardrobe in front of the bed and opened the door. On top of the piled clothes, a delicate wooden box came into view.

He carefully took out the wooden box, picked up a piece of cloth and put it on the table, and then placed the wooden box on the cloth.

The wooden box was opened, and a mini scale that was only about three inches long appeared.

The scale bar was golden, and there were dense scales on the streamlined scale bar. The scale plate was only the size of a child's fist, and it was also golden. The weight was even more exquisite, like a mini pyramid.

A scale, in the name of this era, should be called a centimeter scale.

The so-called centimeter, in this era, is naturally not a unit of length that was widely known in the previous life, but a unit of weight.

Liang, Qian, Fen, Li, Hao!

It is the fine weight unit of this era.

Compared with the previous life, there is no difference between one liang and one liang of meat in the previous life. One qian is about three or four grams in the previous life, and one fen is about 0.34 grams, and the following centimeters can be deduced by analogy.

As for larger units, such as shi and dou, it is obviously difficult to reflect on medicinal materials.

And the weight that can be weighed by this mini scale in front of him is accurate enough to centimeters!

And the most accurate scales that can be bought on the market basically stop at money.

This scale that can be accurate to millimeters is probably not enough to describe its rarity!

This centimeters scale, which can be called a treasure, can appear in his hands. The fundamental reason is obviously thanks to Mr. Li of Mingxin Hall.

Otherwise, at present, he obviously cannot get this centimeters scale, whether it is money or connections.

Knowing people and medicines, whether the medicinal properties are accurately controlled or not is directly related to the perfection of the final medicinal properties.

The importance of this centimeter scale was obviously very clear to Chu Mu who had just embarked on this path.

Chu Mu carefully took out the centimeter scale from the wooden box, and used his strength to control it without reservation.

"This may not be accurate enough..."

After weighing out a dollar of medicinal materials, Chu Mu looked at the scale in front of him, but he was greedy and thought like a snake swallowing an elephant.

The ultimate perfection of medicine lies in the control of its properties.

But now, even this centimeter scale only controls the weight of medicinal materials, and it only controls the weight of centimeters.

Although the weight of medicinal materials also corresponds to the medicinal properties in a sense, it is obvious that this correspondence is rough and approximate rather than precise.

To achieve true perfection, there should be direct control over the medicinal properties.

For example, with the white peony root in front of him, he wanted to neutralize the cold medicinal properties of the white peony root and neutralize the overall medicinal effect. However, he wanted to remove the other medicinal properties of the white peony root through the combination of other medicinal materials.

If he could control it accurately, he should directly take a millimeter of the white peony root, or a penny of the yin-cold medicinal properties. This would obviously be the real perfection.

Thoughts flowed, and in the end, Chu Mu also laughed at himself. This was really too ambitious. At the moment, he was still new to the step of weight, and being down-to-earth was the way to go.

If he can really reach this point, if he keeps going steadily, one day he will come into contact with it.
