Jiang Feng was the last to take out the ordinary Dan furnace. Compared with other people's Dan furnaces, his Dan furnaces, which he used to often use to make talismans, were too stingy.

His Dan furnace is less than half a foot high, and the furnace body is not much bigger than an adult's fist, but it is not a three-legged or four-legged Dan furnace, but more like a small oil lamp.

From the outside, there is no texture decoration, not even runes, and it is bare.

When Jiang Feng's Dan furnace appeared, it caused laughter.

Jiang Feng's Dan furnace is no better than a child's toy.

"Damn, this big dark horse of Mingcheng Academy is too funny, how can he take out such a simple Dan furnace, he can't change it from an oil lamp, can he purify medicinal materials?"

"I don't think this Jiang Feng understands alchemy at all, he's just perfunctory!"

"Don't pretend to be a pig and eat a tiger. ”

"Hmph, you look down on him, with such a Dan furnace, it's no wonder that he doesn't fall last!"

The audience in the east was disappointed when they saw Jiang Feng take out a very small and rudimentary Dan furnace. In stark contrast to him, the number ten player of the adjacent Martial Spirit Academy, that Dan furnace was stronger than Jiang Feng.

Not only is the appearance beautiful, but also the surface of the embossed beautiful pattern, from a distance, it looks like a ball of flame flying, pleasing to the eye.

But at the same time, there are still some people who are optimistic about Jiang Feng, because in the first round of identification of medicinal materials, Jiang Feng played well, can accurately identify medicinal materials, and believes that there is no problem in purifying and processing medicinal materials.

"Ladies and gentlemen, let's get started now. Seeing that the contestants were almost ready, the referee ordered someone to light three incense sticks and announced the official start of the second round of the purification competition.

At this time, the contestants are busy, compared with the first round, the second round is not sufficient, there is no time to rest at all, and it is still difficult to purify ten different medicinal materials successively.

The most important point is that the temperature required for each medicinal material is not the same, the temperature is too low to purify the purity is not enough, the temperature is too high, it is easy to destroy the medicinal materials, only at the best temperature can the purification purity be the highest and the effect is the best.

Then there is purification depends on the efficiency, for example, a plant of two taels of herbs can be purified five drops of pure liquid medicine, if the operation is not done properly, it is likely that only three or two drops can be purified, but if the operation method is skillful and the temperature is appropriate, it is possible to purify five drops, or even six drops beyond the level.

This is the purification rate.

In other words, the success of purification is only one aspect, and the purification rate is the most important.

Jiang Feng looked at the ten medicinal herbs placed in front of him, and did not immediately start to operate.

His Dan furnace was the lowest among the twenty people, and the efficiency was obviously not as good as theirs, and what he had to do was to arrange the order of these medicinal materials reasonably, so as not to waste fire sources and unnecessary consumption time.

What needs to be done now is to arrange the ten herbs in order, and arrange the ten herbs in order from low to high at the desired temperature.

Undoubtedly, he had to start by refining the medicinal herbs with the lowest temperature, which saved a lot of time.

If the temperature required for the first herb is very high and the temperature for the second herb is low, the Dan furnace can only be cooled after the first herb has been purified, which is a waste of time.

The purification temperature of the second medicinal material is lower, and the purification temperature of the third medicinal material is higher, so after the purification of the second medicinal material, it will be heated again, which is obviously a waste.

And if you arrange the temperature required by the ten herbs from low to high, it will greatly save time.

However, the problem came again, Jiang Feng identified these ten medicinal materials one by one, and found that only seven of them could be identified, and the other three medicinal materials could not be determined in any case.

It's a bit of a hassle.

Jiang Feng breathed a sigh of relief, first arranged the seven known medicinal materials in order, and then quietly used the eagle eye.

He can think of refining in the order of discharge, and naturally others will think of it too. Those who can represent the college in the top ten competitions, which one is not the best in a thousand.

Even if you are not proficient in alchemy, I believe that you still have this brain.

Sure enough, after Eagle Eye scanned it, Jiang Feng found that nearly half of the other nineteen people, like him, were not busy preheating the Dan furnace, but sorting the medicinal materials one by one.

By comparing with each other, the order of Hua Yueying and the others is relatively scientific, at least consistent with the seven medicinal materials that Jiang Feng ordered.

Jiang Feng finally adopted the order of Flower Moon Shadow and put the other three medicinal herbs in.

I secretly praised Hua Yueying in my heart, not to mention that this woman is quite talented in alchemy, which also shows that the resources she obtained before are unimaginable.

The various superiorities of the big family made Jiang Feng both envious and jealous.

In addition to envy, Jiang Feng was not idle in his hands, and also began to preheat the Dan furnace.

The purification of the first kind of medicinal materials is very smooth, although the Dan furnace and the fire source are the worst, but Jiang Feng's control ability is still very good, he is very skillful in manipulating the temperature of the Dan furnace, and accurately purifying the medicinal materials.

The purified liquid was slowly poured into a small medicine bottle, and it was victorious.

Each herb has three chances, and the purpose of the competition is to see the quality of the purification.

Generally speaking, a group of three medicinal materials, under the prudent circumstances, will only be purified one after another, and it is impossible to put all three medicinal materials into it at one time.

The biggest disadvantage of purifying one by one is that it takes a long time.

Jiang Feng successfully purified the first part of the first medicinal material, and then, in order to save time, threw the remaining two parts into the Dan furnace at the same time.

The risk undoubtedly increases, and if you fail, you will lose two-thirds of your points!

But this is not a problem at all, because the purification of a simple part and the purification of two parts are only different in quantity, and the required temperature and heat are almost the same.

It's just that it's riskier.

But Jiang Feng is not alone.

Several other people had already started to do this, because the Dan furnace and the fire source were stronger than Jiang Feng, they had already completed the purification of the first medicinal herb and began to prepare the second medicinal material.

In fact, even if it is purified, there will be differences in progress due to the different furnaces and fire sources, as well as operating methods.

Among the twenty people, except for Jiang Feng, the other nineteen were all using beast fire.

Especially with water like smoke, Fan Zhengrong, Guo Kanfeng and Hua Yueying are all demonic beast soul cores that refine fire attributes, and use their own spiritual power to control beast fire.

For the rest, to be unambiguous, they used domesticated small fire-attribute demonic beasts to give orders to them, and they spit flames to burn the Dan furnace.

In comparison, the Jiangfeng flame is the worst and the flame temperature is the lowest.

Although there is no obvious difference in the temperature of the flame between the domesticated fire attribute demonic beasts and the refined beast fire, the difference in fire control ability and flexibility is not small.
