What is Sandan? Unlike lead and mercury, this is a road that is far from being talked about by the general public.

Chen Yu looked through the book, the cover was not old, and he thought that it was either a new work or had been copied.

Sure enough, I heard You Ke say: "Hahaha, I expect that the Taoist will be interested in this Dan book." ”

Earlier, he had obtained it from a semi-secluded Taoist temple south of the Five Lakes and carved it in bamboo slips. Fortunately, the handwriting is clear, although the master in the Taoist temple can't tell the origin and source, but after some research, You Ke still deduced the seven, seven, eighty, eight, and copied the entire Danshu.

"Looking at the records in the book, it should be after Dakang, when Yin Shang was made, and his person called himself Fengyunzi, and all the things contained in this volume are the methods of seeking the way and alchemy."

Having said that, Chen Yu found that the above Dan was very different, almost no mention of lead and mercury, but a lot of pharmacology involved, although there may be some differences between the name in ancient times and today, but with the medicine knowledge that accounts for a large proportion of the book, it is not an exaggeration to say that it is a medical book.

"Yin Shang?"

Hearing You Ke's words, he had a correlation in his mind.

This Yin Shang is very different from the Yin Shang of the previous life, in the land under his feet, there was a dynasty eight hundred years ago, the name of the Great Yin, the founder of the country is the Shang family.

Collectively it is called Yin Shang, or Shang Yin. It's not close to now, it's not far away. At that time, Taoism had already risen, and Taoism would go back hundreds of years. If we blindly follow what the Tao Sutra says, there was an eternal Taoism when the heavens and the earth first opened, of course, it is completely unbelievable.

However, Dayin is indeed the era of the prosperity of Taoism.

"Eight hundred years, how did this bamboo slip survive? Is it really miraculous? The Book of Heaven? ”

"Originally, the old man was also amazed, with the texture of ordinary bamboo, it was difficult to preserve it to this extent even if there were various methods."

You Ke said with a smile, it turned out that the bamboo slips he got were also copied and sorted out by a certain Taoist sage.

Not even one, for more than 800 years, the world's dynasties have been changing, and Da Yin, who is known as the prosperous era of Taoism, has also fallen apart.

"Xu is a bystander and a copy, and he wandered for decades or so, and was finally found by the old man in the corner of the Taoist temple."

Chen Yu nodded, feeling that it should be so, although there were often ancient bamboo slips unearthed in the previous life, but those were also incomplete, Rao has far more technical support than the current one, and it is very difficult to restore.

And this bamboo slip is so well preserved, I don't think it will be too long in the coming years.

Then, the two talked about "Feng Pu Sandan" for a long time, and each had their own gains.

Chen Yu is far inferior in pharmacology, but in the same way, the other party, a half-informed layman, is even worse than him in terms of Taoist manager.

After all, it is a Dan book, and some Taoist words and phrases in it may sound remote and profound to others.

Chen Yu also struggled to read, but it was much better than Youke.

"There are eleven kinds of pills recorded on it, but five of them are of unknown type, and it is not clear whether they are extinct or misannotated."

When I closed the book, I heard You Ke sigh. The reason why he wanted to copy this Dan book was that the pills recorded did not contain the poison lead and mercury, and secondly, there were many Dan prescriptions on it for diseases such as dysentery, red tongue, rotten eyes, etc., although they were named with all kinds of Taoist words, but in the final analysis, these diseases that plagued many diseases.

Later, You Ke tried to match a few pairs, and it did have an effect, and it came in handy at a certain time.

It's a pity that many of the above Dan prescriptions have used too many Taoist theories, and they are in the clouds, and it is a headache to study.

However, the prescription is correct, at least some of it has been proven, but the rest is either incomplete or unknown to the ingredients of the herbs, so it is not used.

"There are several kinds of medicinal herbs that seem to have been seen in the Tao Sutra. If you find it later, you can send a copy to the layman. ”

Chen Yu said, this is true, the books written by Taoist priests are sometimes like this, obviously the same thing, and there are other interpretations on the Taoist manager, and the name will be changed.

You Ke thought the same thing, in fact, there were several recipes that were also restored with the help of Daomen friends.

There is more than one Dan book, and giving it to Chen Yu is a good fate.

"When the time comes, you can go to the Huichun Hall in Huayin County."

You can twist your long beard for a smile and leave a place.

Chen Yu silently wrote down that it was too early to send it, and he had to find someone who would go to Huayin, and the caravan could also be used.

In fact, if it was in the Great Zhao period, this kind of thing could be done directly by pretending to be done at the official post station, and at most it would cost another meal and drink.

Hassle-free and convenient.

After that, they talked about the feelings of the north and the south, and the anecdotes of idlers.

"Layman, don't say goodbye."

When Chen Yu left the village, You Ke had to observe for a while to prevent the recurrence of that elder sister Liu's condition.

Although he is strong, he has a benevolent heart.

After a brief conversation, the two made an appointment to see each other again.

"When I go to the Five Lakes, I will definitely take the Taoist to Baili Flower to see the endless sea of flowers."

"The poor road is written down here first, and then you will have to bother the layman."

"Hahaha, that's how it should be!"

……

Qingtai Mountain, Cloud Crane View.

In the evening, dragging large bags and small bags, Chen Yu slowly walked up the stairs.

Under the peach tree, a chestnut red deer was half-lying on the ground, with half a pink petal hanging from its mouth.

He looked stunned for a moment, looked at the peach tree and looked left and right for a while, and then breathed a sigh of relief. Look at the ground again, it's clean, not as colorful as before.

Yo~

"Eat everything on the ground, you ......"

A little funny, Chen Yu rubbed the other party's head, came to another peach tree on the side, picked one and handed it to the deer's mouth, but the other party sniffed it and turned his head away and ignored it.

Shaking his head, he threw it into his mouth.

It's a little bitter, but it's nowhere near the one next to the deer.

"The idea worked."

However, the deer still stupidly stood under the tree, ignoring the other peach trees.

"It's fine." Chen Yu felt that this was a good thing, he could enclose these peach trees with wooden fences in advance, and save the other party from destroying them.

I have to raise it again.

He thought that the peach blossoms in this world would bloom very late, and the peaches would also be a little later, and it was estimated that they would not ripen until August and September.

Bypassing the gluttonous deer who often came to eat and drink, Chen Yu picked up all kinds of goods purchased from the county town, pushed open the courtyard door and put them on the stone table.

"Oil, salt, soy sauce and vinegar ......"

I bought some of these, which were not expensive except for sauce and salt, and took them out and put them in the stove.

He took out a bundle of oily paper with noodles in it.

It's not as dry as the one seen in the previous life, slightly moisturized, and can't be preserved for long.

Then, there are some ginger cubes, a pot of fruit wine, and a packet of pickled plums in aged vinegar.

They are all seasoning, especially vinegar plums, which were last year, and now there are plums, but they are still very green, far inferior to the bag in their hands.

On the way, Chen Yu has already tasted one, which is sweet as honey after being sour, and has a rich fruity aroma, which can be described as a good seasoning.

It's also good to be a snack.
