On the other hand, seeing Tang Yi's super-strong control and the means to use the exploding fire to speed up the extraction, Master Leng Yichen was extremely shocked, and his unmoved face also moved.

He had never seen Tang Yi practice alchemy, but unlike other alchemists, he did not think that Tang Yi's approach was undesirable, nor did he think that Tang Yi could not complete the extraction. On the contrary, he thought Tang Yi's approach was extremely shrewd, and at the same time It is also extremely subtle, this kind of control and operation is simply fascinating.

In Master Leng Yichen's heart, there is a feeling that tells him that the teenager in front of him can extract the essence of the material within the prescribed time!

Although I don't know why it feels like this, Master Leng is extremely convinced of this feeling.

Unexpectedly, Master Leng was excited and looked at Tang Yi's eyes, looking forward to it a little more.

And the mysterious alchemist in black robe saw Tang Yi's movements for a while, and then showed a look of interest. It seemed that he was also interested in Tang Yi. In his sharp eyes, too A look of anticipation.

"Boom!"

As time passed by, the fire in countless pill furnaces was still burning in the test site. The alchemists were sweating and moving in their hands, trying to extract the essence of the green flame grass.

Although less than one-tenth of the time is left at this moment, it is too late to extract the material, but in this limited time, they still hold such a glimmer of hope and clenched their teeth.

The alchemists are afraid of the high temperature of the fire, and waste the materials, so they control the temperature and keep the temperature below the critical point, a relatively mild state, let it burn slowly, and slowly extract the materials. The essence.

The reason why the alchemist who is still present at the scene has not been eliminated or extracted the essence of the material is to use this method. After all, this is the most stable extraction method, and it is not easy to practice the material.

Of course, in this way, their extraction speed is also extremely slow, whether it can be completed, depends on the will of God.

Where Tang Yi is, unlike other alchemists, he did not choose that kind of safe method, did not control the temperature below the critical point for slow extraction, but instantaneously raised the temperature of the fire to let The burning fire in the red furnace!

The fire in Tang Yidan's furnace is not mild, some are only violent, some are violent, the jumping flames can be seen in people's hearts, and they are very afraid that Tang Yi accidentally damaged the material. !

However, Tang Yi did not have this worry, because although he unlocked alchemy, the operation of alchemy was still carried out by the system in his mind!

There is a systemic anti-sky BUG, Tang Yi's operation can not appear any worse, except that the quality may change due to some environmental and other uncertain factors, there is no other change, he is less likely to extract failure!

In this way, Tang Yi controlled the fire, using methods that others did not dare to think, and found it impossible to quickly extract the essence of the material. The green flame grass gradually changed from the original herbal shape into a powder. All impurities are slowly removed.

"Boom!"

At the moment, the flame in the Tang Yidan furnace was like a layer of sand blowing up and down, suddenly high and low, and suddenly strong and weak, as if disappearing all at once, and it seemed that the explosion drowned everything.

Everyone looked at the heartbeat, and they all squeezed sweat for Tang Yi. Everyone felt that Tang Yi did this, either that it was too late to extract the essence of the material, or that the material was directly scrapped.

After all, the rising flame temperature is not easy to control. If it is too low, the purpose of acceleration will not be achieved. If it is too high, the material will be scrapped. If the flame is suddenly high or low like Tang Yi, the temperature will definitely not be maintained smoothly Uncertainly, the temperature is increased, and all the materials are discarded.

However, it is only Tang Yi who knows best whether he can maintain the temperature smoothly!

Although the fire in his Dan furnace looks erratic, rising and falling, in reality, the temperature is kept at a constant value!

This value is the critical point of 'green flame grass'!

It is the critical point that can extract the essence of the green flame grass most perfectly!

This critical point is precisely controlled by the system, and the temperature of the furnace has been maintained at this critical point from the beginning to the present. It has never been changed, and there is no trace of deviation, which is extremely accurate.

Therefore, Tang Yi extracts quickly!

Although there is not much time left at this moment, this time is enough for Tang Yi!

"Uh!"

After squeezing another rule, Tang Yi's right hand slightly mentioned, the furnace lid of the Dan furnace suddenly opened, and then, numerous green-green crystal powders flew out quickly under Tang Yi's control.

Under the light of the blazing sun, the tiny turquoise powder seemed to be like stars in the sky, very bright.

Tang Yi prepared a container, stretched the container forward, and all the powder in the air entered the container without deviation.

In this way, before the hourglass in front of Liu Cangsong completely leaked, Tang Yi completely extracted the essence of Qingyan grass.

and!

The essence of Tang Yi's extracted materials is crystal clear, completely translucent, and looks extremely exquisite. Each powder is like a piece of art!

Seeing this kind of material essence, everyone needs to know that the purity of the material essence is definitely more than 90%!

It may even reach more than 95%!

Ninety percent and ninety-five percent~www.mtlnovel.com~ In terms of values, it seems that although there is only a difference of five percent, the two are one world at a time, and the quality difference is like a gap. Insurmountable!

Let's put it this way, if the essence of material with a purity of 90% is of high quality, then the quality of the essence with a purity of 95% is the best!

How big is the gap between Shangjia and Need?

Just look at these two words to know.

If the purity of the essence extracted by Tang Yi is really above 95, it will be terrible.

You know, Tang Yi did it when there was only one sixth of the time left. At this moment, not only the essence of the material is extracted in time, but also the purity of the essence of the material is extracted to 95%. Degree, this extraction method, isn't it terrible?

Seeing that Tang Yi really extracted the essence of the material, and the quality of the essence of the material was still extremely high, everyone immediately opened his eyes and started to talk in disbelief.
