All night, Hu Feng didn't practice anything else, just controlling the spiritual fire This kung fu practiced all night, and the night made Hu Feng's control of the spiritual fire more and more proficient, and with the help of the spiritual energy and his own thoughts, the spiritual fire in Hu Feng's hands is just like himself, big is big, small is small, and even so small that the shape that is almost invisible to the naked eye can be realized by Hu Feng.

Looking at Hu Feng's changes, Dan Shen walked over at this time and smiled slightly: "It's very good, I didn't expect you to learn this kung fu overnight, how about it?"

"I feel that this spiritual fire is actually a test of spiritual power, and the spiritual power required is really huge," Hu Feng said.

Dan Shen nodded and continued, "That's right, as long as the spiritual fire relies on spiritual power to control, generally some people have to practice the spiritual fire alone for several years or even more than ten years, and you have the alchemy element in your body After all, you are still a cultivator, so your contact speed is dozens of times that of others, I think according to this speed, it will not take ten days to comprehend."

Hu Feng asked happily, "Don't you need ten days?"

"Of course, I'm just saying that at this rate, it's up to you whether you want to be fast or slow," Dan God said.

Hu Feng nodded, this is also true.

"Next, after the problem of spiritual fire is dealt with, it is time to select medicinal materials, in fact, the medicinal materials of each grade of elixir have never been the same, so which grade you want to practice, then you have to pick it out, here is a list of medicinal materials that I have sorted out, you can take a look" After speaking, Danshen passed a mark to Hu Feng.

After Hu Feng received it, he quickly came up with the names of many medicinal materials in his mind, and the grades reached by the combined medicinal materials were clearly written on them.

Hu Feng was very happy, it was very detailed.

When Danshen saw Hu Feng's expression, he already knew that the other party had seen it, so he continued: "I looked at the medicinal materials around me just now, these are exactly the medicinal materials needed for the pills above the ninth grade, so we can use them to refine them directly."

Hu Feng looked at the medicinal herbs placed in the corner of the wall and asked, "Then how should it be refined?"

Dan God nodded and said, " In the process of firing, you will feel the soft texture of the medicinal materials to adjust the size of the spiritual fire, hard is big, soft is small, until the residue of the medicinal materials is burned in the later stage, the remaining is the essence, often a large number of medicinal materials will form a very small state after refining, this at this time, we will condense all the parts of its essence into the shape of a pill, we call it Ning Dan"

Hu Feng nodded, the people had told him before, so he had always known about it.

Seeing that Hu Feng listened energetically, Dan Shen said directly, "Then let's start."

After speaking, a brown Dan furnace flew out directly from between the sleeves of the Dan God and fell to the ground.

Looking at the Dan furnace flying out, Hu Feng also knew what it was for, but the embarrassment was that he didn't have this thing at all, so Hu Feng asked, "Excuse me, where can I get such a Dan furnace?"

Hearing this, Dan Shen realized that the young man in front of him didn't even have a Dan furnace.

Thinking of this Dan God, he felt a sense of pity, so he said, "Hehe, what's so difficult about this?

When Hu Feng heard this, he hurriedly said, "How does the Dan God cultivate?"

"I'll guide you," Dan said.

At this time, Dan Shen picked a small part of the pile of medicinal materials next to him, and said, "This pile of medicinal materials is enough to refine four pills, I'll give you a little first."

After speaking, he handed a small pile of medicinal herbs to Hu Feng.

Hu Feng took the medicinal herbs and was about to throw them into the Dan furnace, but was directly drunk by the Dan God, "The top cover of the Dan furnace can't be used with your hands, use your aura."

Hu Feng nodded, and after thinking about it, if it was in the late stage of alchemy, the temperature of the top cover would rise, and it would not be very realistic to take it by hand at that time, so he still listened to the teachings of the Dan God, and directly burst out of the aura, and flew up the top cover lying on the Dan furnace.

Seeing that it was completed, Hu Feng threw the medicinal materials into the Dan furnace at once.

The medicinal materials entered the furnace, the spiritual fire appeared, the fundamental Dan God teachings, Hu Feng began to try alchemy for the first time, not only Hu Feng was looking forward to it, but even all the people here were looking forward to it, will an alchemist who can use aura become the second Dan God?

The blazing fire continued to bake the bottom of the Dan furnace, and after a while, the bottom of the Dan furnace had reached the point of redness, Hu Feng kept thinking about the truth of "hard is hot" and kept baking, but after a while, a burnt smell floated out of the Dan furnace, and the Dan God on the side shook his head and said: "The fire is too big, it's mushy."

When Hu Feng heard this, he quickly extinguished the spiritual flame.

Then Hu Feng took out the remaining medicinal materials with the help of aura, only to see that the previous medicinal materials had turned into ashes.

Hu Feng was not discouraged and said: "Come again"

At this time, he walked to the pile of medicinal materials by himself, and according to the medicinal materials needed for the refining of the Nine Pins Pill in his mind, he picked them out, and then began to refine them again.

Lan Yi looked curiously looking forward to Hu Feng's success.

When the second pile of medicinal materials entered the furnace, Hu Feng closed his eyes again and began a new round of refining, this time Hu Feng knew that the fire could not be turned on too much at the beginning of the road, and it was necessary to do it step by step, so the flexibility in the palm of his hand was obviously much smaller than the last time, Hu Feng carefully felt the texture of the medicinal materials in the furnace to change the size of the flame, this time Hu Feng put the perception in the furnace, so the situation of the medicinal materials in the furnace was clearly controlled by Hu Feng, according to the texture of the medicinal materials, Hu Feng continued to refine for about an hour, and finally most of the medicinal materials in the furnace had been refined clean, and Hu Feng felt the furnace when he felt it, There is not much left of the medicinal materials before the discovery, and the color has begun to become a little pale, Hu Feng was overjoyed, and then held his breath and shouted, "Ning Dan"

At this time, a stream of aura was directly entered into the Dan furnace, and began to wrap the remaining medicinal materials, Hu Feng knew that the remaining medicinal materials would definitely be the essence, if you didn't hurry up and condense the Dan, it would definitely fail.

The continuous wrapping of the aura slowly began to transform the essence inside into a circular shape, and at the same time, Hu Feng was also controlling the aura with his own mind, and when a completed pill slowly rose from the Dan furnace, Hu Feng shouted happily: "Success"

However, the pill in the air was directly split apart after Hu Feng shouted later, turning into pieces.
