The strong medicinal fragrance permeated the Dan room, and the smell of it made people feel intoxicated, and even Zhen Yuan had a trace of excitement.

But even if everyone present was not good at alchemy, they knew that Chen Zhengyi's alchemy had failed again.

Chen Shuangyue comforted her brother worriedly, but Chen Zhengyi didn't realize it.

Wang Zhong walked over to take a look and found that the inside of the Dan furnace was the same as last time, it was the same puddle of medicinal liquid, but this time the medicinal liquid had a little golden color, and there was a rich fragrance permeating the surroundings.

Zheng Jingyue also came to the side to take a look, and after a while, he asked curiously: "Chen Daoyou, did he fail when he received Dan?"

The Song family has been prosperous in Bihan City for a long time, and the pill industry is also one of the pillars of the Song family, Zheng Jingyue is also well-informed, and he knows a little about alchemy.

Chen Zhengyi finally nodded in a deep groan when he heard this: "Yes and no, the medicine does not become a pill, it is true that there seems to be something inappropriate in the method of collecting the pill, but since the pill is not successful, this medicine should have a foul smell and poison, but now it is a strange fragrance, which makes me unsure of my idea." ”

Chen Shuangyue, who was on the side, hurriedly asked suspiciously: "But brother, the medicinal materials you bought are all things that nourish qi and replenish the yuan, even if you can't practice the pill, the residual medicinal liquid has some medicinal properties, it should be considered normal, right?"

Chen Zhengyi looked at Wang Zhong when he heard the words, and then said: "If it is an ordinary pill, it is like this, but the refining method of this pill is extraordinary, and the erysipelas produced by the excessive nourishing qi of the pill are pulled out at the last moment of receiving the pill, and it is obviously wrong for such a situation to happen." ”

Wang Zhong looked at the medicinal liquid in the Dan furnace for a while before frowning and asked, "Then Chen Daoyou has any ideas, what is the problem?"

Chen Zhengyi thought for a while, and then said quite solemnly: "If I guess correctly, it should be that there is something wrong with one of the medicinal materials, dare to ask Wang Daoyou, this acacia seed, is it really a year-old flowerless acacia seed?"

Wang Zhongleng for a moment, this prescription was made public by the Heavenly Alliance in the previous life, and then spread to the rebels, but Wang Zhong himself didn't know how to make alchemy, he just collected it, but he didn't know much about the medicinal materials in it.

The acacia seed that Chen Zhengyi said is indeed a medicinal material in the prescription, but he really doesn't know what it really looks like.

"Could it be that there are several kinds of Hehuanzi?" Wang Zhong couldn't help but ask.

Chen Zhengyi nodded and said: "Acacia is a very common aquatic medicinal material, but this thing cannot grow in lake water, it can only grow on the shore of the water, and with the fluctuation of water vapor, it changes in the growth process. ”

"When the moisture is moderate, the acacia seeds will grow normally, and finally blossom and bear fruit, and the fruit is a sesame-like particle, but it is very toxic, and the birds will die if they eat it. However, this kind of acacia seed has the effect of inducing erysipelas and dissolving residual properties in alchemy, so it is occasionally seen in the medicine of some pills. ”

"And when the water vapor is insufficient or the water vapor is excessive, the acacia seed will not bloom, and it will grow until the end, without flowers and fruit, this kind of acacia seed is also a rare medicinal material, which can have the effect of replenishing qi and benefiting the middle, and it is often used in alchemy. ”

"However, although the two look the same, there are still some differences, the former will smell an indescribable fishy smell, while the latter has a faint smell of grass, do you know which one it is?"

Wang Zhong was stunned for a moment, he really didn't know this subtle difference.

"I really don't know about this, but since I know the problem, why don't I try both, and I can always try it, right?"

Chen Zhengyi sighed and said: "Generally speaking, the acacia seeds sold in pharmacies are the latter, because the natural environment is ever-changing, and most of the acacia seeds that can be found are the latter." This time, the acacia seeds we bought are all like this, if you want to find the former, I don't think this Akiyama Castle will be sold. ”

Wang Zhong suddenly frowned: "Then where can I get it?"

Chen Zhengyi hurriedly said: "It's not difficult to obtain, the growth conditions of acacia seeds are not harsh, and even many watersides are distributed, but if you want to obtain acacia seeds with moderate moisture, you must carefully identify and store them, and you must not store them at the same time as the latter, otherwise the efficacy of the medicine will also change." ”

Chen Shuangyue hurriedly said, "I remember that there are several big lakes near Qiushan City, why don't we go and find them now?"

Chen Zhengyi nodded and said, "Yes, but remember, I'd rather pick a little less at a time, and never mix it with other acacia seeds." ”

Wang Zhong said, "Then how can we tell whether this acacia is suitable or inappropriate?"

Chen Zhengyi hurriedly said: "This is simple, just smell it carefully, with a faint fishy smell, it is the former, on the contrary, it is the latter with a fragrance, but generally speaking, the acacia seeds are clustered, the fragrance is flourishing, and the taste of the former is easy to be covered, which is why there are few former in the world." ”

"And the former is relatively scarce, and the price is not precious, so many people don't know how to distinguish it carefully. ”

Wang Zhong immediately clapped his hand: "Then without further ado, we will go outside the city now to pick suitable acacia seeds." ”

Chen Zhengyi nodded and said, "That's fine, the three of you go to pick acacia seeds, and I'll deal with other medicinal herbs here." ”

Zheng Jingyue asked suspiciously, "Chen Daoyou is not going?"

Chen Zhengyi's eyes were filled with indescribable brilliance, staring at the Dan Furnace Dao in front of him, and said vigorously: "If my estimate is correct, it is really a problem of Hehuanzi, as long as I have the correct Hehuanzi, I am confident that I can practice this furnace Dan within three days, but this requires some preparation." ”

Hearing him say this, Zheng Jingyue didn't ask any more, Wang Zhong still believed him, and immediately took the two women out of the city.

Akiyama Castle ruled over a vast territory for thousands of miles, and although there was no special spiritual land, it was precisely because of this that the monk families in the territory were very loosely distributed.

Almost as long as it is suitable to establish a mountain, there is a family occupancy, as the spiritual place of the family.

Even the mortal society is not isolated from it, and the immortals and mortals blend together, and they get along very well.

More than 100 miles north of Akiyama Castle, there is a micromirror lake, with deep blue waves, calm as a mirror, and pleasant scenery.

This micromirror lake covers an area of dozens of miles, showing a long and narrow trend, there is a mortal fishing village by the lake, and on a small hill next to it, there is also a small Xiuzhen family located here, other than that, there is nothing special.

Hehuan Zi is not a precious medicinal material, even mortals pick, concoct, and then sell it to cultivators for alchemy, but Hehuan Zi itself has a faint toxicity, and the general mortal physique is not strong enough, and it is easy to die of poison if exposed to too much, so few people make a living from it.

The three of them acted separately outside the Weijing Lake, along both sides of the Weijing Lake, all the way to the carpet search, and they really encountered two clusters of acacia seeds on the way, but the fruits on them had already been picked clean, and only the lonely branches were left, which had no effect.
