After eliminating the impurities again, Tang Yi can get the purest material essence after fusion, so that in the last step of 'condensing the pill', he can also refine the purest pill, the success rate of the pill condensation, and the quality of the condensed pill can also be further improved.

All in all, this step of re-refining is indispensable.

And Tang Yi was refining again at this moment, still using a different fire, and still not using an alchemy furnace.

After all, whether it was refining the Nine Heavens Cihang Flower before, or refining the fused materials at this moment, it was not something that ordinary flames could do. If normal flames can't be used, then you can only use different fires.

The reason why the alchemy furnace is not used is also because with the quality of the ordinary alchemy furnace, it can't withstand the baking of different fires at all, and it is useless to use it, so Tang Yi can only use different fires to directly refine the materials.

A moment later, under Tang Yi's subtle control (perhaps it is more appropriate to say that it is under the subtle control of the system), the mixture formed by the fusion of the four materials was once again successfully refined by the Three Thousand Yan Flames, and the impurities were basically discharged, and this step was basically completed at this point.

At this moment, if you want to refine the material into an elixir, then there is still the last and most critical step, 'Ning Dan'.

Only by condensing the material into an elixir can it be regarded as the real completion of alchemy, if this step cannot be completed, then the previous steps are all in vain, so this step is extremely critical, there can be no sloppiness, and there can be no carelessness.

At this moment, although Master Lu didn't believe that Tang Yi could refine the elixir, he didn't dare to disturb Tang Yi after reaching this step.

After all, Ning Dan is the most critical, the slightest wind and grass may make the alchemist Ning Dan fail, this is a great taboo among alchemists, if an alchemist harms another alchemist Ning Dan to fail, this will be spurned by 10,000 people in the alchemy session, and in serious cases, the identity of the alchemist will even be abolished, so even if the alchemists have a deep holiday, they will not disturb each other.

Not only Master Lu, but the others also held their breath, looking nervous, as if they were afraid that a slight movement of their own, or even a slight breath, would make Tang Yi Ning Dan fail, if Tang Yi Ning Dan failed, they would also be extremely guilty in their hearts, and everyone present was also nervous, and they were careful not to make any sound.

And Tang Yi was in this silent atmosphere and began to carry out the last step of Ning Dan.

"Whoa!"

Tang Yi's hands shook rapidly, pinching all kinds of complicated handprints.

In mid-air, the flames of the three thousand Yan were still burning fiercely.

The mixture formed by the fusion of four materials was burned under the fire of Sanqianyan, and once again eliminated impurities.

Although impurities have been discharged several times in the first few steps, there are still impurities in the mixture, and in the process of coagulation, these impurities still need to be excluded, so that the coagulation can be better carried out.

As the mixture excludes impurities, Tang Yi also controls the mixture to slowly move closer, and then squeeze and solidify.

It is an extremely difficult operation to solidify mixed materials such as powder liquid, after all, before the fusion of these materials, the characteristics are completely different, after the fusion together, what are the characteristics of the mixed materials obtained, the fixed point is geometric, it is also difficult to master, a careless, maybe at the moment of condensation, the material will be scrapped, so when this step of condensation, you need to be very careful, slowly groping to carry out.

Of course, Tang Yi is controlled by the system to operate, and there is no worry about this, what are the characteristics of the material, what is the fixed point, these are clearly calculated in the system, Tang Yi's actions are also implemented after the precise calculation of the system, so there is no need to worry about the material will be scrapped.

The only thing Tang Yi needs to worry about is the quantity and quality of the pills refined, although with the system to operate, the alchemy is foolproof, but the quality and quantity of the final refined pills still depend on luck.

In this way, under the control of the system, Tang Yi's operation has almost reached perfection, and the mixed materials are under the control of Tang Yi, without any deviation at all, and they are perfectly condensed together.

And as time passed, in mid-air, around the hybrid material, a misty white mist began to be formed, like a dream, which was unrealistic, enveloping the hybrid material.

"It's going to be a Dan!"

Seeing this mist, Hua Duo suddenly said excitedly.

Although he is still an alchemy apprentice, although his alchemy experience is not very rich, however, Hua Duo has never eaten pork, and he has seen his own master alchemy, every time he is about to become a pill, around the material, there will be such a misty and mysterious fog, this fog, also has a name, called Cheng Dan fog, which is regarded as a precursor to Cheng Dan.

On the other side, seeing such a piece of Dan fog appearing, Master Lu's face was pale, and he had nothing to say, he had indeed underestimated Tang Yi before.

He didn't expect Tang Yi to have such an excellent refining technique, let alone that Tang Yi could fuse it in an instant! And the most difficult condensing pill step, Tang Yi also completed it perfectly, and he couldn't find any fault at all.

With such a technique, Master Lu is simply beyond the reach of the dust.

At this moment, the elixir is ready, the overall situation has been decided, even if Master Lu is reluctant, he has to admit that the fifteen or sixteen-year-old boy in front of him has an excellent alchemy level, even Master Lu himself is not comparable to this alchemy level.

Of course, at this moment, Master Lu doesn't think that he has lost!

Because, the content of their bet is to cure Xiaoxin's disease, although Tang Yi's alchemy technique amazed Master Lu, although Master Lu thought that he was not Tang Yi's opponent, but Master Lu did not think that Tang Yi could refine the elixir to treat Xiaoxin's condition!

That's a semi-terminal disease, how can it be so easy to refine an elixir for the treatment of a semi-terminal disease?

Therefore, at this moment, Master Lu was not discouraged, he was still staring at Tang Yi tightly, watching Tang Yi's alchemy, wanting to see what kind of pill Tang Yi could refine!

And that's just the time!

"Boom!"

Suddenly, a thunderclap sounded in the sky, and a thunder snake slashed down wildly!

Coincidentally, the Razer happened to be split in the fog of the alchemy room, it seemed, it was split on the mixed material that was about to take shape?

Struck by lightning?

This is......

Everyone was startled by the sudden thunder and lightning, but before they could react to what was going on, a second lightning bolt slashed down from the sky again.
