Ye Feng looked at the direction in which Murong Su left, he didn't know what to say, and he didn't know what his mood was at the moment, but this was Ye Feng's choice, so he had to face this alchemy.

Ye Feng came to the front of this tripod and sat down cross-legged, and used the wood on the side to place it under the tripod one by one, but when he finished all this, he suddenly found that there were no flints and flints here, and without flints, these woods could not make fire at all.

"How could this person be like this, he thought about letting me use wood for alchemy, why didn't he equip me with a flint and steel, it's really ...... Ay! With that, Ye Feng took out two pieces of wood, forcibly pierced a hole in one of them with his fingers, and then made the other piece of wood into a stick, and one end of the stick was still a pointed head, and then Ye Feng put the remaining sawdust on top of the wooden block with holes, and let it cover the hole on it.

After doing all this, Ye Feng picked up the stick with a pointed end, stuck the pointed end in the hole in the wooden block, and then put his hands together and clamped the stick in it and quickly rubbed it.

After a while, a trace of smoke came out of the hole where the wooden block was held......

After a while, the smoke in the hole of the wooden block became even thicker, Ye Feng took the stick out of the hole, poured out the burning sparks inside it and wrapped it with the surrounding sawdust, and then held it in his hand and blew it up again and again with his mouth.

……

"It's been a long time since I've used drill wood to make fire, I'm really tired this time, but what herbs should I put in it, this Murong Su doesn't know how to tell me." After Ye Feng had grown the flames under the Ding to what he thought was suitable, he came to the corner of the wall where the herbs were placed, and he smiled bitterly as he looked at the herbs everywhere.

Squatting down and looking at the herbs on the ground, from time to time he would pick up the memorization herbs and observe them carefully, perhaps too focused on studying these herbs, and when he came back to his senses, he found that the flames under the Ding behind him had been extinguished, and only some sparks remained.

So he went to Ding's side again, and lit the flames one by one with the wood beside him, but at that moment the door of the house was slammed open.

"Ahem...... What is this, why are you so choking, what are you doing, how can this be, I'll just go out and you'll make this place like this? ”

After Murong Su entered the room, she saw that the entire room was shrouded in smoke, although it was not very rich, but this was the first time Murong Su had seen this situation in her life, so her anger suddenly stopped.

Ye Feng heard that it was Murong Su's voice, so he looked up and looked around, only to see that the smoke in it had spread all over the room, so he came to Murong Su's side, pulled him out of the room, and said calmly, "No way, this is the disadvantage of using wood to make a fire." ”

"Okay, today's is my fault, this is the formula for alchemy, you just need to refine it according to the refining method on it to refine the pill, don't forget not to fill the whole room with smoke anymore, so choking people I don't want to go in." Hearing Ye Feng's words, Murong Su's face flushed a little, and after smiling awkwardly, he took out a book from his storage belt and handed it to Ye Feng.

After taking the book that Murong Su gave him, Ye Feng hugged his fists to show his respect, then turned around and walked towards the room, and when he walked to the door of the room, he turned his back to Murong Su and whispered: "Thank you, but I still hope that you can knock on the door first when you come in, even if this is your medicine garden; And please find some flint and steel. ”

"But ......"

After Ye Feng finished speaking, he walked into the room and closed the door, Murong Su looked at him and wanted to say something but couldn't say it, after Ye Feng closed the door tightly, she looked at the room and said to herself, "Do you really want to do what Qingtong said, you have completely changed, Mo Yan ...... Ye Feng ...... Brother Xuanyuan, I don't know how to face him. ”

After that, Murong Su turned into Changhong again and left here, and his direction was the direction of Xuanyuan Xin's immortal cultivation side.

Ye Feng extinguished the fire in the room at this time, and then he sat on the ground next to him and looked at the alchemy book that Murong Su had given him.

……

I don't know how long it took, Ye Feng read the book roughly, and he learned from it that this so-called alchemy is actually not very difficult, only fire, tripod and herbs are needed to refine, but the grade of the refined pill is very different, and the content of the same pill and the order in which it is put in can also lead to changes in the effect, and even more so, the original good elixir can become a harmful poison.

"Alchemy is really not simple, it seems that this alchemy is completely out of the mood of the alchemist, but I don't know how strong the poison can be?" As Ye Feng was talking, he put the book in his hand aside, came to the corner of the wall where the herbs were placed, and looked at these herbs, and a trace of light flashed in Ye Feng's eyes.

"Thousand leaf leaves, kite flowers, mossy grass; These three flavors can refine the Scattered Spirit Pill, maybe after I refine these pills, I can quickly gain the upper hand when fighting with others. As he said that, he picked up the three herbs and put them into the ding, and began to refine them after the red flame rose under the ding.

As the name suggests, this herb is the elixir used to dissipate the spiritual power in the body of the person it takes, and these elixirs may not have much effect on those who have already formed the pill, but it is effective for foundation building and qi refining period.

And this simple dissipation of spiritual power can be described as fatal to people in the Qi refining period, because the monks in the Qi refining period cannot make the spiritual power in their bodies circulate, they can only store it inside; And even if a person in the foundation building period can let the spiritual power circulate in the body, so that the spiritual power in his body can really become his own thing, but because the amount is not enough, if the temporary loss of spiritual power is placed in the middle of the battle, it will be a fatal problem.

The flame is constantly swinging, and the temperature of the tripod is also constantly rising, until it rises to the highest, and the effect of the flame below it is used to keep warm.

"When the temperature of the Ding rises to the maximum, remove the lid of the Ding and let it cool down quickly, and then reduce the flame under it to keep the temperature of the Ding in moderate, and then close the lid of the Dan furnace ......"

In a low voice, Ye Feng began to operate step by step according to the refining method described in the book he had recorded in his memory.

After a while, there was a slight humming sound from this ding, and then this ding absorbed all the flames under it, and then stopped after humming slightly for a while, but it did not emit the medicinal fragrance like Murong Su refined.

Ye Feng opened the lid of the tripod and looked inside, only to see two black pills lying quietly inside, and these two pills had obvious cracks on them.

"Did it fail, did I not manipulate it?" Ye Feng showed a hint of regret in his eyes, and returned to the side of the book of refining pills, turning it to the page that recorded the Scattered Spirit Pill and watching it himself, even so careful that he would not miss every word.

"Do you feel sorry for your failure? I didn't expect you to be such a pessimistic person. ”

Just when Ye Feng was fascinated, the door was opened again, and this time the voice that came into Ye Feng's ears was not Murong Su, but her father, Ling Yunzi, the head of the Ling Feng faction.
