(The second one is sent, a little tired, good night everyone...... Thanks to the "Phantom Thousand Wind God", "Aspiring Bird Boy", "Go to the Dead Regiment Z1", "The Army Soul is in the 9", "Bamboo Courtyard Leisure" for the reward of several children's shoes, and thank you for the comfort of the brothers and sisters in the idle crowd, and then ...... Both men and women are welcome to come and soak me...... ）

Lu Donglai continued to repeat the previous steps, and when he reached the fourth step, his aura appeared lacking again, and the sweat on his forehead was bursting out, and a mistake was another failure.

"Don't I have the talent for alchemy?

The cow's temper came up, and no one could stop it, and at this moment, Lu Donglai seemed to have a bit of the momentum of killing gods and killing Buddhas.

An hour later, Lu Donglai's aura returned to its peak state again.

However, this time he did not try it lightly again, but carefully looked at the materials on the ground to refine Hongyan Dan, he picked them up one by one and compared, and through the annotations of the third master on all the materials in the "Hongyan Dan Chapter", dozens of minutes later, Lu Donglai picked up two medicinal materials in his hands, one left and one right.

One of the herbs was dull in color, like a sweet potato, but the texture was softer, while the other herb was bright red in color and extremely hard, but Lu Donglai discovered that they had a property, that is, they were the main materials used to neutralize and stimulate the pill in the second and third steps at the same time.

"Because it's a first-grade pill, the flame I control is only refined with scorching fire, but if I do the second step and the third step at the same time, and then refine it with fierce fire, will that work?"

For Lu Donglai, if he has this idea in his mind, then he will put it into action.

This time the furnace was restarted.

The first step is to bake over a blazing fire.

Succeed!

The second step was also refined with scorching fire, and when it was about to end, Lu Donglai suddenly switched to 'fierce fire' to refine, and the temperature of the flame instantly increased a lot, and Lu Donglai's forehead was sweating, but at the same time, he quickly added the refining process of the third step to the second step.

All of a sudden, the flames became a little uncontrollable, and at the same time, all the medicinal materials in the furnace were added at once, which produced an even stronger reaction, and there were constantly small explosions.

Lu Donglai touched the sweat on his forehead with his sleeve, but he didn't dare to interrupt the output of the fierce fire, the consumption and output of such aura was extremely depleting to Lu Donglai, just a short time of kung fu, and it actually made the aura in his body directly volatilize one-fifth.

At this rate, his aura would not be able to support it in less than half an hour. But you must know that the time of the previous refining failure also lasted for nearly an hour.

But at the moment, Lu Donglai had no time to care about those, and he devoted himself to alchemy.

Although this furnace alchemy directly merges the end of the second step with the third step, at present, there should not be a failed furnace, since there is no failure, then it means that there is still a certain possibility of success?

As long as there is no failure, there is no possibility of stopping!

He, Lu Donglai, is not a person who gives up halfway.

After about seven or eight minutes, the explosion in the alchemy furnace was much quieter, and finally calmed down, and Lu Donglai also smelled a faint smell in the alchemy furnace at this time.

"Failed?"

It's a little blind...... If you fail, you should have a reaction, not all of them steam came out all of a sudden, and then 'poof', which announced that the entire alchemy process had failed, but what is your situation now? Just give me a taste and ...... And then it's gone?

Was that a failure or a success?

It's just that Lu Donglai can't use his head to see if the pill inside has failed, after all, the temperature inside is too high, and this proximity is only afraid that the whole handsome little face will be ruined.

Since there is no way to determine whether it is a success or a failure, Lu Donglai naturally does not want to waste this opportunity, fortunately, the materials given by Yu Zhiqiu are enough, otherwise Lu Donglai's temperament may not dare to try like this.

The output of the fierce fire was not reduced by half a point, Lu Donglai added the fourth step in, the first two failures were in this step due to the lack of spiritual energy, but now under the output of the fierce fire, the time is shortened, which allows it to successfully perform the fourth step.

Bang Bang Bang ~!

After adding the fourth step in the alchemy furnace, there was a stronger reaction again, like a small pea bursting inside, and like popcorn, Lu Donglai didn't dare to be distracted, and continued to input spiritual energy.

The cold sweat on his forehead kept falling, but the pill in the alchemy furnace still didn't have the slightest reaction, Lu Donglai couldn't help but be anxious, wouldn't this alchemy also end in failure? The aura left in his body now is not much, it is not enough to support about five minutes, but according to this urine, don't say five minutes, even ten minutes may not be able to do it.

"Wouldn't it really be necessary to cultivate until Zhuji has more aura to have a way to refine this furnace of Hongyan Pill, right?" Lu Donglai smiled bitterly, but he didn't give up easily, he had come to this point, even if all the aura was consumed, he had to try to see if he could refine Hongyan Dan.

Time passed minute by minute, Lu Donglai was sweating profusely, as if he had just been salvaged from the water, not only that, but his heartbeat was also beating very fast, 'bang bang bang' kept beating.

Two minutes.

Three minutes.

Lu Donglai was almost on the verge of collapse.

At this time, the movement in the alchemy furnace suddenly became a lot smaller, and at the same time, a fragrance was transmitted from the alchemy furnace.

Lu Donglai was overjoyed in an instant, and the aroma came out, didn't that mean that it proved that the elixir in the alchemy furnace was about to succeed?

Lu Donglai, who was about to despair and wait for collapse, instantly seemed to be beaten with chicken blood, as long as people have hope, they will have motivation, obviously the Hongyan Pill in the alchemy furnace is going to succeed, this is a hope.

Five minutes later, the movement in the alchemy furnace was almost inaudible, and at the same time, the fragrance was even more diffuse, and at this moment, a more elegant fragrance came to his nose, and Lu Donglai knew that his pill had succeeded.

When he let go, Lu Donglai sat on the ground without any image.

After resting in place for a few minutes, Lu Donglai got up and opened the alchemy furnace, and at the same time reached out and grabbed a red face pill from it, but just like that, Lu Donglai was dumbfounded.

In his hand, it was an irregular and even uneven black elixir.

"This ...... How is this completely inconsistent with the appearance of Dancheng recorded in the "Hongyan Dan Chapter"? What about the good red and round? The color is not right, and it is not round, can this thing be regarded as Hongyan Dan...... Still reluctantly......"

finally succeeded in refining a furnace, but the elixir obtained was like this, and Lu Donglai wanted to cry without tears.
