On the other side, seeing Tang Yi's super control and the means to use the soaring furnace fire to speed up the extraction, Master Leng Yichen Leng was extremely shocked in his heart, and his unfazed face was also moved.

He had never seen Tang Yi perform alchemy, but unlike other alchemists, he didn't think that Tang Yi's method was undesirable, nor did he think that Tang Yi couldn't complete the extraction, on the contrary, he felt that Tang Yi's method was extremely shrewd, and at the same time, it was also extremely subtle, and this kind of control and operation was simply amazing.

In the heart of Master Leng Yichen Leng, there was a faint feeling that told him that the young man in front of him could extract the essence of the material within the specified time!

Although he didn't know why he felt this way, Master Leng was extremely sure of this feeling.

Unconsciously, Master Leng became excited, looked at Tang Yi's gaze, and looked forward to it a little more.

And the mysterious alchemist in the black robe was also slightly stunned when he saw Tang Yi's movements, and then, with a look of interest, seemed to be interested in Tang Yi, and his sharp eyes also showed a look of eagerness.

"Whoa!"

Time passed bit by bit, and in the competition venue, the furnace fires in the countless Dan furnaces were still burning, and the alchemists were sweating, moving in their hands, and trying to extract the essence of the green flame grass.

Although there is only less than one-tenth of the time left at this moment, it is too late to extract the materials, but in this limited time, they still hold on to a glimmer of hope and grit their teeth and persist.

Because the alchemists were afraid that the temperature of the furnace fire would be too high, they would waste the materials, so they controlled the temperature to keep the temperature below the critical point, a relatively mild state, and let it burn slowly, slowly extracting the essence of the materials.

The reason why the alchemists who were still insisting on the scene had not been eliminated and did not extract the essence of the material was because they used this method, after all, this is the most secure extraction method, and it is not easy to practice the material.

Of course, in this way, their extraction speed is also extremely slow, and whether it can be completed or not depends on the will of God.

And where Tang Yi was, unlike other alchemists, he didn't choose that kind of safe method, and did not control the temperature below the critical point to slowly refine, but instantly raised the temperature of the furnace fire, making the furnace fire in the Dan furnace burn fiercely!

There is no mildness in the furnace in Tang Yidan, some are only violent, some are only violent, and the jumping flame makes people's hearts straight, and they are very afraid that Tang Yi will be careless, and the materials will be broken!

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

There is a bug in the system, Tang Yi's operation can not appear any bit bad, except that the quality may change due to some uncertain factors such as the environment, it is impossible for others to change, and it is impossible for him to fail to extract!

In this way, Tang Yi controlled the fire, using methods that others couldn't think of and thought were impossible, quickly extracting the essence of the material, and the green flame grass also slowly changed from the original shape of the herb to powder, and all the impurities were slowly eliminated.

"Whoa!"

At this moment, the flames in the Tang Yidan furnace are like cascading wind and sand, high and low, strong and weak, as if they disappeared all at once, and as if they were overwhelmed by a storm.

Everyone looked at the heartbeat, and they all sweated for Tang Yi, everyone felt that Tang Yi was doing this, either he didn't have time to extract the essence of the material, or he directly wasted the material.

After all, the soaring flame temperature is not easy to control, low, can not achieve the purpose of acceleration, high, and the material will be wasted, like Tang Yi The flame is high and low, and the temperature must not be maintained smoothly, maybe if the temperature is high all of a sudden, all the materials will be wasted.

However, whether the temperature can be maintained smoothly or not, only Tang Yi himself knows best!

Although the fire in the furnace seems to fluctuate, rising and falling, in fact, the temperature remains at a constant value!

This value is the tipping point of 'Green Flame Grass'!

It is the tipping point that can extract the essence of the Green Flame Grass perfectly!

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

Therefore, the speed of Tang Yi extraction is very fast!

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

"Huh!"

After pinching another law decision, Tang Yi's right hand was slightly raised, and the lid of the Dan furnace was lifted with a bang, and then, countless blue-green crystal powders, under Tang Yi's control, flew out quickly.

Under the scorching sun, the tiny grains of blue-green powder seemed to be like stars in the sky, extremely bright.

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

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

And!

The essence of the material extracted by Tang Yi is crystal clear, completely translucent, and looks extremely exquisite, and every particle of powder is like a work of art!

Seeing this kind of material essence, needless to say, everyone knows that the purity of the material essence is definitely more than 90%!

Maybe even more than 95 percent!

Ninety percent and ninety-five percent, in terms of values, although it seems that there is only a difference of only 5 percent, but the two are the same world, and the gap in quality is like a chasm, which is insurmountable!

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

How big is the gap between the best and the best?

Just look at these two words.

If the purity of the material essence extracted by Tang Yi was really above ninety-five, then it would be terrifying.

You know, Tang Yi didn't do it until there was still one-sixth of the time left, at this moment, not only did he extract the essence of the material in time, but also extracted the purity of the essence of the material to the extent of ninety-five percent, isn't this kind of extraction method terrifying?

Seeing that Tang Yi had really extracted the essence of the material, and the quality of the essence of the material was extremely high, everyone's eyes suddenly widened and they began to discuss in disbelief.
