Next, Jiang Feng once again preheated the Shaoyang Nanliding that had cooled, first used a simmer, and carefully put the smelled Peiji Dan powder into the Dan furnace.

The main purpose of simmering refining is to identify the type of medicinal materials from the point of view, because the temperature required for medicinal materials is more or less different, as long as the temperature is carefully controlled, it can be identified in a certain temperature range.

What surprised Jiang Feng even more was that the purity of this Pei Ji Dan was not very high, and there were still a small amount of impurities and waste in these Pei Ji Dan fragments he had removed.

This makes the difficulty of identification a lot less!

Extremely careful to control the temperature of the flame, Jiang Feng also used the Eagle Eye to the strongest degree. The 7th Flavor Herb, the 8th Flavor Herb, the 9th Flavor Herb......

The situation was surprisingly smooth, after a few minutes, counting the medicinal materials he had sniffed out before, Jiang Feng had already accurately identified the thirteen flavored medicinal materials! But there were many good things, just when the fourteenth medicinal material was determined, a small flaw appeared, and with a "poof" sound, those Pei Ji Dan powders instantly turned into flying ashes, and a pungent smell wafted out from the lid of Shaoyang Nanliding.

For the first time, Shaoyang Nanliding successfully identified the seven flavors of medicinal materials, which is also relatively good.

Fortunately, this Pei Ji Dan only picked off a small part, and Jiang Feng had to pick some off the Pei Ji Dan again and throw it into Shaoyang Nanli Ding.

As the refining continues, so does the difficulty. Because the initial identification of medicinal materials is not very difficult, it is rare later, when the volunteers identify the twenty flavors of medicinal materials, the problem comes.

It is not feasible to only identify through the refining of Shaoyang Nanliding, and there are at least five kinds of medicinal materials that have never been successfully identified.

After one attempt after another, Napei Jidan had already been used by Jiang Feng for most of it, but the identification had come to a standstill and there was no progress.

Jiang Feng had to stop and consider whether there was any other way to test it, don't end up running out of Pei Ji Dan, and he couldn't identify all the medicinal materials, and finally ended up with a bamboo basket to draw water, which would be worth the loss.

A single piece of Pegidan was auctioned at the trade fair for a high price of 100,000 gold baht!

Adjusting his mood slightly, Jiang Feng compared the twenty flavored medicinal herbs he had listed according to their medicinal properties, combined with the medicinal herbs that he couldn't identify and didn't dare to determine when he used Shaoyang Nanliding to refine just now, and tried to match them.

This is similar to picking up stones inside beans, although the stones and beans left after screening are about the same color and size, but they are different before, pick up a bean and stone, the quality of the two is not the same, carefully observe the finish of the outside is not the same, no matter how bright and round the stone is, it can't catch up with the bean.

Jiang Feng was making this kind of comparison, using several medicinal materials that he suspected to try to add to these twenty medicinal materials for comparison, and the medicinal properties were repulsed, and those that could not be fused were eliminated.

A quarter of an hour later, through this relatively primitive method, Jiang Feng once again identified three medicinal materials, and in the end, only two medicinal materials were clueless.

At this moment, Fang Zhongyong came upstairs, he went to purchase a batch of medicinal materials according to Jiang Feng's instructions, and now he wants to send them up, don't delay Jiang Feng's refining.

Jiang Feng asked Fang Zhongyong to put down the medicinal herbs, and asked him about his recent situation, Fang Zhongyong's progress was surprising, he originally had no talent in alchemy, but the stupid bird flew first, and diligence could make up for his clumsiness, Fang Zhongyong was very hard under Jiang Feng's guidance, and now he was able to refine several of the simplest pills alone, which could be regarded as a rapid progress.

Fang Zhongyong retreated, Jiang Feng was still about to identify Pei Ji Dan's medicinal herbs, but a strange medicinal fragrance made him stop. Turning his face to look at the medicinal herbs that Fang Zhongyong had put down, it was where the medicinal incense came from.

Jiang Feng walked over, opened the medicine bags one by one, and finally found the source of the strange fragrance.

The reason why he had doubts about this was not that he made something out of nothing, but that this medicinal herb was simply a mistake by the medicinal herb shop, and Jiang Feng was very clear about the type of elixir he refined, because he didn't need this kind of medicinal material.

It seems that the guy at the herb shop was careless and confused the herbs he listed. However, the purchase list was still stuffed on a medicine bag, Jiang Feng picked up the list and scanned it, and immediately knew what was wrong.

It turned out that although the medicinal properties of these two medicinal materials are very different, they are similar in appearance, and it must be that some careless young man did not pay attention to the names of the medicinal materials, but confused the two medicinal materials by intuitive mistake.

Alchemy is not stir-frying, you can eat it if you mistakenly pour soy sauce into vinegar, but if the medicinal materials are confused, the pill can't be refined!

Jiang Feng put the herb in a separate piece, and returned to his body to analyze the ingredients of Pei Ji Dan.

However, this time, as soon as his ass sat down, he suddenly jumped up like a spring.

"By the way, isn't this medicinal herb the ingredient of Pei Ji Dan that I suspected before" Jiang Feng's eyes lit up, and the depression just now was swept away, and his heart immediately lit up.

Jiang Feng grabbed this flavor of medicinal materials, and without hesitation, he threw himself into Shaoyang Nanli Ding, the flames were rapidly raised, and in the Dan furnace, this flavor of medicinal materials was quickly refined and turned into powder.

Turn off the heat and open the lid. Jiang Feng had no intention of refining this herb into a liquid, and it was in powder form, which was the most suitable for him to study the properties of this herb.

Put the powder of the herb in the palm of your hand, and put the powder of Pei Ji Dan aside, the two correspond to each other, and sure enough, this herb is one of them!

Jiang Feng was relieved, the so-called unintentional willows and willows were shady, just now Fang Zhongyong was really his lucky star, bringing him a chance to unlock the ingredients of Pei Ji Dan.

Now, there is only one medicinal herb left to figure out, but Jiang Feng's heart is extremely cheerful.

Regardless of the process, he was close to knowing all of Pei Ji Dan's medicinal materials, which meant that he was only one step away from refining Pei Ji Dan. Of course, at the juncture, sometimes you can't reach it quickly, Jiang Feng understands this truth.

He had just gone to take a sip of tea, when Fang Zhongyong ran up again and said, "Master, who is that...... Deng Wenzhong is here!"

Deng Wenzhong proposed it more than once yesterday, and today he asked Jiang Feng to make him another elixir to consolidate his unspeakable secrets. Now it seems that he did take it to heart.

Jiang Feng said casually: "Zhongyong, you just give him a Tongluo Pill, by the way, don't tell him the name of the pill, and charge him an extra ten gold baht, this kid will not be slaughtered for nothing, and if he is slaughtered, he will be slaughtered for nothing." ”

When Fang Zhongyong heard this, he smiled and said, "Master, I didn't expect you to do this, I thought that the Medicine Fragrance Pavilion would treat everyone equally......

Of course, this is a joke, Jiang Feng's face was flat, "We can't be too rigid in doing business, if we don't make anyone's money, Deng Wenzhong's money won't be made in vain!"
