In the spacious alchemy room, in addition to the medicinal fragrance that filled the entire air, there were also golden walls all around. A flame burst out of Lan Feng, and the Dan furnace seemed to be detonated, and instantly turned into a fire furnace, and the flames in the furnace beat irregularly, imprinting on the surrounding golden walls, like a giant dragon opening its teeth and claws, soaring clouds and mist.

Lan Feng took the lead in throwing the prepared soul nourishing grass into it, but he dispersed his soul power to control the fire, and after a while, his face turned slightly pale, and then beads of sweat were clearly visible on his face. Alchemy is a very soul-consuming thing, if it weren't for the fact that Lan Feng's soul power cultivated by relying on the Casting God Chapter was much stronger than that of an alchemist of the same level, I am afraid that it would be even more embarrassing at this moment. Moreover, there are not many exercises for cultivating soul power, so it is not easy for Lan Feng to reach this level, and if he is replaced by an ordinary third-grade alchemist, the situation will not be much better.

Lan Feng stared intently at the Soul Nourishing Grass in the Dan Furnace, and it wasn't until nearly an hour before the Soul Nourishing Grass turned into an inky black liquid, and Lan Feng loosened his shoulders that had been tense and exhaled a turbid breath.

Next was the Xuantian Fruit, a turquoise fruit with pink thorns on it, which was casually thrown into the Dan furnace by Lan Feng, and then controlled the flames to melt it, as for the medicinal liquid of the Soul Nourishing Grass before, it was only temporarily put aside to continue refining.

Beads of sweat the size of rice grains began to appear on Lan Feng's head, compared to the extraction process of the Soul Nourishing Grass, in fact, the Xuantian Fruit was much easier, but the consumption of refining the Soul Nourishing Grass before was not small, and there was no recovery in the middle, and the pressure increased sharply at this moment.

Looking at the medicinal herbs that gradually turned into liquid, Lan Feng smiled happily in his heart, fortunately, his efforts were not in vain, and he finally succeeded.

"Not good!"

Just then, Mrs. Qing shouted.

"Madam, is there any problem? Didn't I see how well he practiced?" asked the maid beside Mrs. Qing a little strangely.

"I can sense that his soul power has reached the third-grade level, and I have to say, he is really a genius. Mrs. Qing showed an approving gaze, "It's just that this Dan furnace is made according to my requirements, and it is generally used by a third-grade alchemist, I'm afraid that the soul power is not enough to support the completion of the pill refining, and he is afraid that he will fail." ”

Lan Feng naturally heard it, and said secretly: Why didn't you say it earlier, this is going to kill me!

But he can't sit still, he has to continue, he is not willing to admit defeat easily, this is his first alchemy, it is too embarrassing to only do this step!

So, Lan Feng continued to extract all kinds of medicinal materials, and put a total of fifteen kinds into the Dan furnace before and after, at this moment, the flames in the Dan furnace began to weaken, which also had a certain relationship with the attenuation of his spiritual power, after all, his true cultivation was only the triple level of gathering spirits, that is, the influence of the exercises, and the strength of spiritual power was only equivalent to the fivefold realm of gathering spirits, and it was still a little difficult to support a Dan furnace furnace fire customized by a four-grade alchemist.

At this moment, the medicinal herbs in the furnace fire have basically reached the completion of extraction, and the last one is missing, the demon flower.

When a dark blue flower was thrown into the Dan furnace by Lan Feng, Mrs. Qing's beautiful eyes turned, what kind of flower was it, it seemed to be very familiar. It's no wonder that she just feels familiar, because the demon flower is a very common herb, and it is not even a elixir, because this kind of flower grows around the habitat of the spirit beast, and it is everywhere, but only ordinary people use it to make medicinal materials to treat some diseases or something, and the warriors are used to it when they see this thing, and they ignore its existence at all.

The dark blue flower danced in the reddening flames, slowly changing its true color and beginning to turn into a black liquid.

"Oh no, his soul power is almost exhausted!" Lady Qing said.

At this was the critical moment, Lan Feng naturally sensed the problem, how could his soul power be consumed so much when extracting medicinal materials? It seemed that he had to waste it once.

Naturally, what he thought of was the small Divine Pill refined by Qianji, but he didn't expect it to come in handy so soon. But it's still distressing to think about it, after all, a second-grade pill is also worth a lot of money in the market!

He took out a medicine bottle from his arms, poured out a pill, and there were a few pale golden veins on it, just watched it in his hand for a moment, then stuffed it directly into his mouth and swallowed it.

Mrs. Qing's eyes widened, if she was not mistaken, it was a second-grade pill with five golden patterns, and among the second-grade pills, it was the best.

The moment the pill entered his abdomen, the majestic power flowed like a stream of water, and he immediately felt a little more clear in his brain, and his soul power also became full, and the eighty percent consumed before came back in an instant, and now he was in a wonderful state. He couldn't help but sigh that the pill deserved to be an elixir, that is, it was strong.

But looking back, he let this Mrs. Qing give the pit, not to mention that there is a problem with this Dan furnace, and he also remembered to remind him of most of his consumption, no one will believe this anywhere. But this kind of thinking is just thinking about it, now that the extraction process has been completed, the next step is to come to the key to alchemy, that is, the fusion process, smelting!

Because of the strange properties of the Heavenly Book World, although Lan Feng had only studied alchemy once, he had extremely proficient memories in his mind, so that he could easily grasp the balance of medicinal materials.

The demon flower needs to be fused at the end of this process, the purpose of which is to make the essence of various medicinal materials not conflict and stabilize the medicinal properties. In the process of alchemy, there is only one consequence of the conflict of medicinal materials, the fryer. In other words, once it is not grasped well, the medicinal materials of this furnace will be completely destroyed, and the generally poor quality Dan furnace will also be scrapped.

Lan Feng carefully manipulated his soul power to squeeze all kinds of medicinal liquids to promote fusion, and gradually, gradually, the pressure in it became more and more intense, and the original black liquid began to turn green.

Mrs. Qing squinted her eyes slightly, of course she knew that this was the process of smelting, and there was something wrong with Lan Feng's smelting, that is, there were too many conflicts between various medicinal materials, and if she continued like this, she might explode!

"Stop! There is a conflict between the medicinal properties of the herbs, and they will blow up the furnace. Lady Qing shouted at Lan Feng. After all, she is a fourth-grade alchemist, and her eyesight is far beyond that of ordinary people, in her opinion, if Lan Feng continues, there is only one result, and that is the fryer.

Lan Feng smiled slightly, as if the feeling of exhaustion had dissipated.

He stared closely at the liquid medicine to fuse, but the repulsive force was getting bigger and bigger, and the delicate balance between the liquid medicine was likely to be broken, and even a sizzling sound had already appeared. At this moment, Lan Feng used his soul power to control the medicinal liquid of the demon flower to enter it, and a strange scene appeared, several medicinal liquids that were originally mutually exclusive, under the effect of the demon flower, slowly fused, and the speed was very fast, and the degree of fusion was also very high.

"It worked! How could this be!"

This scene made Mrs. Qing's eyes widen, her lips opened slightly, and the disbelief in her eyes was self-evident.

Lan Feng didn't care about this, because there was an important step soon, which was Cheng Dan.

The medicinal liquid was tumbling back and forth in the Dan furnace, and the original black medicinal liquid was finally displayed in a fist-sized turquoise color, and those different kinds of medicinal materials had been completely fused together at this moment, but the flames in the furnace seemed to be a little unable to hold on.

Madam Qing also observed it, and then a spiritual power entered it, and the flames continued to rise, Lan Feng nodded slightly towards Madam Qing, and continued the work at hand.

The difference between Lan Feng's alchemy this time and Qianji's previous is that there will be seven to twelve pills in a normal furnace of pills, and generally speaking, twelve pills are called full furnace pills, which is the best. Lan Feng saw that the time was ripe, a rejuvenation seal finger trick was engraved on the pill, and the pill was immediately formed, and then after he hit eleven fingers in a row, the flames around the Dan furnace began to explode, flooding the entire Dan furnace, and in less than a quarter of an hour of trial, the flames on the Dan furnace dissipated by themselves, followed by the fragrance of medicine that came to his face.

Mrs. Qing couldn't hold back anymore at the moment, and hurriedly ran up to help collect the Dan, Lan Feng was almost consumed at the moment, and someone would naturally not refuse to help.

"Oh my God, it's actually twelve all-colored five-pattern pills, what kind of freak are you kid?" Mrs. Qing was surprised, but also showed a puzzled look.

Lan Feng immediately took one and swallowed it in one gulp, and then the mental tiredness disappeared, he was slightly stunned, and said, "It seems that the medicine is stronger." ”

"The rest is for you, I kept two of them, and you also know that I need to convince the guys from the Alchemist Guild, otherwise who will help a newcomer 'Blue Star' refine the elixir!"

Lan Feng nodded, accepted the remaining pills, and then left the pills and more than a thousand sets of medicinal materials he had brought with him, and at the same time told Mrs. Qing some details of the Little Returning Divine Pill, and he didn't leave until everything was arranged, but it was already midnight at this time.
