As soon as they saw that they were going to refine the Rejuvenation Pill, many of the alchemy disciples present showed bitter expressions.

It is true that the Rejuvenation Pill is very simple, and everyone present can also refine it. It is one thing to refine it, how to improve the quality of the Rejuvenation Pill is a big problem, after all, what is assessed this time is the quality. What's more, the Rejuvenation Pill is a bit out of the way, if it weren't for the pill that was often refined, it would be impossible for ordinary people to refine it of good quality.

Let's talk about the quality of the pill here, generally speaking, the quality of the pill is divided into five levels: waste pill, inferior quality, middle quality, superior quality, and the best pill.

First of all, these five levels are visible to people with the naked eye, and if they are subdivided, there is no way to divide them at all, and the quality of each pill is different. It's like there aren't two snowflakes in the world that are exactly the same.

The quality of the pill depends on the number of impurities, and everyone knows that the less impurities, the better the quality of the pill. It is said that the best pill is free of impurities, but in fact, it is just alchemists deceiving themselves, and the best pill is not without impurities, but there are very few impurities.

The quality of the same two top-grade pills is different, even if it can't be seen with the naked eye, but it is just different.

Of course, it is impossible to distinguish it with the naked eye, and people also have a way to distinguish the quality of the pill, which is very simple, the pill with more impurities is heavier, and the pill with fewer magazines is lighter. This is the only criterion for judging, so people have invented a method called the "float and sink method".

The floating and sinking method is not difficult, and it can be done by simply arranging a simple formation.

~~~~~~

Taking a deep breath, everyone calmed down and began to alchemy. The top 100 event is related to the fate of the people present, once it enters the top 100, the value doubles, and everyone has to wait for it.

Glancing at everyone, Li Mu found that alchemy geniuses such as Nie Xiaoling, Qi Xiaobai, Jiang Qiujun, Miao Fengxian, Luan Yu, and Mu Wanxi all looked relaxed, obviously they were very sure of entering the top 100.

For them, the first two rounds, whether it is the knockout round or the top 100 competition, are not a big problem.

The next two rounds of the top 10 and the championship are the most important.

Brush brush brush ~~~

One by one, the disciples sacrificed the alchemy furnace, the alchemy curtain opened, and the temperature rose in an instant, and a hundred flames were gorgeous.

Retracting his gaze, Li Mu also began to refine the pill.

The eight-hundred-year-old eight-section periwinkle, which is the main medicine of the Rejuvenation Pill, in addition, there are two elixirs that are more than five hundred years old, namely the Earth Dragon Root and the Flame Fruit.

In order to refine the Rejuvenation Pill well, these three elixirs must be refined. Among them, the Earth Dragon Root and the Flame Fruit are one yin and one yang, and their melting points are different, but they must be put in together, because alchemy pays attention to the balance of yin and yang. This is the biggest difficulty in getting them to release their power at the same time.

Old God Li Mu was there, and he casually threw the eight sections of Changchun grass into the Dan furnace, waited for a while, and then put in the earth dragon root and flame fruit at the same time, and then continued to play the magic trick to control the spiritual fire, so that the Dan furnace could cause three different temperatures.

While melting the two elixirs, it is also necessary to pay attention to the changes in the eight sections of periwinkle, and to add other elixirs before they are completely melted.

"That's it. ”

Of course, this point is not difficult for Li Mu, seeing that the time is ripe, he quickly threw in one elixir after another.

It didn't take long for all the elixirs to turn into viscous. After removing impurities, the liquid medicine is basically semi-dry, the purification has been completed, and the next step is to melt the pill.

After melting the pill, the pill is formed, and the surface of the pill is uneven, and the pill at this time can be called the pill embryo, and after a special method, the pill becomes round and shiny. This process is called Gudan.

Woohoo!

Li Mu's fingers flew over, like a butterfly piercing flowers, dazzling to see, and one after another aura tricks entered the interior through the Dan furnace.

The rough surface of the elixir changed, becoming shiny and round, transparent like glass.

At this time, the alchemy is basically completed, the body of the pill is stable, and if it does not encounter extreme cold or heat, it will basically not crack.

Of course, if the Dan furnace is opened at this time, the temperature drops sharply, or the temperature suddenly increases, it will still lead to the failure of alchemy.

The next link is warm recuperation, the process of warm recuperation, which can also be said to be the process of slow cooling.

First, the spiritual fire slowly weakened, and then waited for the natural cooling of the Dan furnace, and the elixir was refined.

"Po~~~"

At the bottom of the Golden Crow Cabernet Furnace, the faint flame finally disappeared.

"Out of Dan!"

A light drink sounded, there was already a fast action alchemy disciple out of the pill, fast speed is not necessarily good quality, but fast speed is not wrong, as long as the change of the pill can be controlled, it doesn't matter.

The first one to come out of Dan was a petite girl, she was Nie Xiaoling, Danfeng's recognized first-day disciple.

"Out of Dan!"

The second is Miao Fengxian, she is also very fast, only half a note slower than Nie Xiaoling. Again, speed alone can't judge quality, which is not scientific.

Brush!

A touch of green flashed in front of the two of them, and the pill was immediately held in the palm of their hands.

"The best elixir! is the best elixir······ Although it was only a flash in the pan, it was still seen by sharp-eyed people, and the two of them both refined the best elixir.

Subsequently, Qi Xiaobai, Jiang Qiujun, Luan Yu, Mu Wanxi and others came out one after another.

Woo Woo Woo ~~~

After another half of the tea, green pills flew out of the various alchemy furnaces, and all the people refined the pills, and only a few people failed to refine them.

Li Mu also showed his pill at this time, and the verdant pill fell in the palm of his hand, and the whole body was green, like green glass, which was extremely beautiful.

"It's of high quality, the masked man can! ”

"He's strong, he's a big rival, he's qualified to be in the top 100. ”

"It's just a high-quality elixir, I thought he could refine the best elixir, but that's it. ”

In the crowd, many people were secretly paying attention to Li Mu, and when they saw that his alchemy was completed, they spoke one after another.

"That's good for your elixir, let's test the quality of the elixir next. ”

At the same time as Xuan Feizi spoke, a formation mage came out and casually arranged a formation, which was a simple floating and sinking formation, with only one function, which was to test the quality of the pill.

The formation is not large, only about two meters in diameter, and the whole is octagonal, flashing with a hazy white light.

"I'll come first!"

An alchemy disciple casually threw his elixir into the formation, only to see his elixir slowly float up in the formation, rising to a height of two meters, then stopped, floating there quietly.

The formation is divided into four layers, each of which is one meter. They correspond to the quality of the multiplication, the quality of the medium, the quality of the high, and the best elixir.

As for the waste pill, I'm sorry, it's too heavy to float.

The disciple's pill stayed at a height of more than two meters, indicating that his pill was of the highest quality.
