Seeing that the impurities were separated, Lin Ning didn't dare to relax a bit, and when he felt the blazing temperature of the Dan furnace, he inadvertently, a huge bead of sweat slid down his cheeks and dripped on the ground.

But he didn't know it!

His mind was like a taut string, his two fingers became Zen, and under the movement of his divine sense, the flame of the ancient bottle suddenly rose sharply, completely enveloping the bottom of the Dan furnace.

The temperature rose suddenly, and the heat gradually rose, as if even the surrounding air would catch fire, and the inside of the cave suddenly became unbearably hot. The Dan furnace was also burned red by the invisible fire, and the red light shone brightly, reflecting Lin Ning's extremely serious face.

Despite the unbearable heat in the cave, he did not waver in the slightest.

Another half a day passed, and when Lin Ning felt the gradual emptiness in his body, the medicinal liquid in the Dan furnace finally reacted under the powerful flame.

Lin Ning's mind was immersed in the Dan furnace, and several drops of medicinal liquid were gradually fusing together, but the process was extremely slow.

At first, the liquid medicine condensed and had not yet taken shape, but under the wrapping of the flames, it actually spun up on its own, and a few drops of the liquid medicine were like a small whirlpool, turning faster and faster, and then it formed a pill on its own.

But it was still far from the real elixir, and unfortunately, the aura in the body was suddenly empty and void at this extremely critical moment.

Without the assistance of aura, in an instant, most of the flames in the ancient bottle were extinguished, and only the remaining sparks were swirling around the Dan furnace. Seeing this, Lin Ning was anxious for a while, he didn't expect that the speed at which this fire consumed spiritual energy would be so fast.

It took me a whole night to recover the aura, but it was exhausted in just over half a day, how could I support the completion of Ning Dan?

Originally, Lin Ning didn't want to use the power of the Dao Root, but now, seeing Dancheng, if there is no spiritual energy to continue to supply, he will only lose his previous efforts.

He simply gritted his teeth and had a fierce attack. He has a Dao root, and after accumulation and hard work, he can survive such a certain aura.

The aura that Dao Root stores by itself is the essence of aura, and it is even purer than the aura obtained by one's own cultivation, so it accumulates extremely slowly.

Once this aura is used, it will not take months or even years to recover again, and you will not even think about it. This is the reason why Lin Ning will never use it until the last resort.

Too little is too precious, and it is too difficult to cultivate. Because of this, the amount of this aura is several times better than what you have obtained from your own cultivation, or even more.

It's a pity that his Dao Ming is far from reaching the third layer realm, otherwise if he has that anti-heaven spirit star in his body at this moment, how can he be in such an embarrassing dilemma.

He glanced at the ancient bottle twice hatefully, and said, "If you are really a master who consumes spiritual energy, the spiritual energy that you sucked last time is enough for this alchemy." As soon as he spoke, he finally stopped hesitating, only to see him bite the tip of his tongue, and a drop of bright red essence blood appeared.

He took the drop of blood in his mouth, took his head a little, and swallowed it into his belly.

The essence blood entrance, straight down to the dantian, suddenly the aura surging, gushing out, so that the exhausted dantian was moistened again, like a long drought and rain.

At this moment, the dantian was like a hungry child, hungry like a wolf, absorbing the pure spiritual energy gushing out of the spiritual root. But before it could suck enough, it was stopped by Lin Ning's Guan Yuan acupoint.

Joke! Such a precious thing is not just a waste, a little is enough.

Feeling the abundant dantian, Lin Ning struck the ancient bottle with a spell, and the flames soared in an instant, and its power was far greater than before. This made Lin Ning break out in a cold sweat.

The purity of this aura essence was beyond expectations, and under the soaring flames, it was inevitable that the temperature would be too high and the medicinal liquid that had been refined with great difficulty would be incinerated.

He can't afford to lose it.

Immediately, Lin Ning hurriedly stopped, and then almost choked the flames.

Finally, he felt the temperature for a while, and after making sure that there was nothing wrong, he breathed a sigh of relief, stabilized his body, and continued to condense the pill.

The long condensation lasted for three days.

In the past three days, Lin Ning has not closed his eyes once, and his small face has become dry red and cracked because of the long exposure to high temperatures, and because of the high concentration for a long time, his face has also become pale.

But he didn't feel a trace of tiredness, and at this moment, he was very excited in his heart, because he could feel that Ning Dan was almost finished. My first alchemy was about to succeed.

He continued to keep his eyes wide open, and his body was like a rock, standing beside him, not moving.

Finally, when it was approaching evening, when he suddenly heard an extremely crisp sound in the Dan furnace, there was no movement, his heart moved, he was overjoyed, and he couldn't wait to open the lid immediately.

But I saw that in the huge Dan furnace, there were two thumb-sized, brown Dan pills. "Could this be the lowest-level detoxification pill?" He sniffed the smell of medicine and instantly knew the name of this pill.

He couldn't help but be stunned, he had worked hard to refine two of the lowest level detoxification pills? The detoxification pill is the most inferior of the pills.

Not one of them!

The lowest level of pills that ordinary people can buy, and the rich, who are a little richer, directly use it as a medicine to treat wind, cold and fever.

"The detoxification pill is the detoxification pill, it is better than failure." He was still comforting, and was reaching out to take it out, but as soon as he touched it, a hot sensation spread throughout his body in an instant.

"It's hot!" As if he had been bitten by a poisonous snake, he was shocked and retracted his hand sharply, and he couldn't stop blowing. He had forgotten that the freshly baked pills had to be cooled before they could be taken out, otherwise the residual warmth left by the alchemy would burn his hands.

After a long while, the residual temperature in the Dan furnace dissipated, Lin Ning took it out, and when he took the two inconspicuous pills in his hand, he took a closer look.

Suddenly, the whole person was completely stunned in place!

"Danwen? There is still Danyun? After a closer look, Lin Ning finally couldn't hold his breath, and actually shouted twice in a row, "This ...... That's not right. As soon as the words came out, the next moment, he couldn't help laughing anymore.

Wowha!

I saw that there were black lines on the two brown pills, and after counting, there were as many as four, and the second one not only had a Dan pattern, but also a faint layer of white mist appeared next to it.

It's Danyun without a doubt!

These two signs will only appear on the best elixir, and the so-called elixir is the one in ten thousand, the elixir of medicinal properties. When the Dan is completed, if there is a pattern, it is the best in the medicine, and if there is a white mist, it is the holy product in the Dan.

Dan is the essence of medicine, and the fog and pattern mean that this Dan is the essence of the essence, the holy product of the gods, 10,000 good pills, can not be exchanged for a pill with Dan patterns, not to mention the appearance of Danyun Dan.

This is a well-known thing for the warriors of the entire continent.

But throughout the thousands of years on the mainland, only a few people have seen this kind of elixir, and even now, it has turned into a legendary existence! Even if it is the lowest-level detoxification pill, if there are Dan patterns and Dan clouds, it will immediately become a priceless treasure!

At least, in the mortal world!

At this moment, Lin Ning guessed that the ancient bottle flame could make this pill so ungodly, and the ancient bottle flame was indispensable! He did not hesitate to use the purest aura of the Dao root to refine it.

What's more, the Dan furnace still has the qi of the purple sky, and the righteous qi condenses the Dan, which is extraordinary.

He held the two pills in his hand like a treasure, for fear that he would fly away as soon as he let go.

Well, the more I appreciate these two pills, the more I feel beautiful and wonderful. Lin Ning sat there regardless of his physical fatigue, looking over and over vigorously.

As if admiring two peerless beauties, their eyes are full of gold stars.

After a while, he came back to his senses, and it occurred to him that there were so many herbs at the moment, wouldn't it be beautiful if he could take this opportunity to refine a few more?
