At this time, Ye Feng was looking at the orange flame that appeared on his right hand, which was the result of his repeated several times.

"Elder Xiao, why does refining medicine require the Yuan Force Fire of Fire System Cultivation to be able to do it?, can't the others?" Ye Feng didn't understand why.

"In fact, refining medicine does not have to be the Yuan Li Huo of the Fire System Exercises, other Yuan Force Fire is also possible, but compared with the Yuan Force Fire of the fire system, the heat will be much lower, which will greatly reduce the rate of Cheng Dan, and over time, the fire system Yuan Force Fire will be regarded by the world as an inevitable element of alchemy" Xiao Lao explained.

"Elder Xiao, what if there is a Heavenly Fire, do you still want to use the Yuan Fire to refine the medicine?" Ye Feng asked, he had seen that Xiao Lao used the Heavenly Fire Python Fury Flame whether he was refining the pill or making the medicinal juice, and he had never used the Yuan Fire, which may also be the reason why Xiao Lao did not have Yuan Power, but he still wanted to ask, when there was a Heavenly Fire, did he still need the Yuan Fire to refine the medicine.

"Nonsense, with the Heavenly Fire, who would use that garbage Yuan Huo, the Heavenly Fire is the supreme heaven and earth spiritual object of the mainland, and it is a piece of cake to burn the mountains and steam the sea, not to mention that it is used to refine medicine!" Xiao Lao said loudly.

"Eh, hehe!" Ye Feng smiled on his lips, in fact, he was very firm in his heart, he would get a heavenly fire no matter what in the future, it was too good, and it was still a piece of cake to burn the mountains and steam the sea.

"Okay, now I'll start refining the pill, you have to see clearly, how I did it. Xiao Lao said to Ye Feng, and then with a slight wave of his hand, one of the five materials of the Qi Gathering Pill mixed together was separated, and then it floated up and flew to Xiao Lao's side.

Xiao Lao waved his hand again, and the medicine refining furnace also floated up like the material and flew to his side.

"Look!" Xiao Lao said again, and a fire python sprang out of his right hand.

With a wave of his hand, the fire python left Xiao Lao's right hand and flew into the alchemy furnace.

With the entry of fire, the medicine pod, which was dark and flat, and was unusually cold, became fiery red.

"Xiao Feng, when refining medicine, you must use the power of your soul, feel the strength of the fire at all times, and properly control the fire, if the fire is too big, the elixir will be burned, and if the fire is too small, the elixir will not be refined, you have to remember it. Elder Xiao continued to teach Ye Feng the key points of refining medicine.

"I see!" Ye Feng replied.

"Okay, then I'll start!" After Xiao Lao finished speaking, he grabbed a medicine tree floating beside him with his left hand, and also grabbed one with his right hand, and with a wave of both hands at the same time, the medicinal herbs in his hand flew towards the medicine tripod.

Before the medicinal materials flew to the medicine tripod, the lid of the medicine tripod was opened, and the medicinal herbs flew into the medicine tripod along the mouth of the tripod.

The first moment after the refining materials entered, the lid was closed.

"Xiao Fengzi, when refining medicine, you must wrap the entire medicine tripod with your soul power, in addition to controlling the fire at all times, you can also know the changes in the elixir you are refining!" Xiao Lao's voice once again came into Ye Feng's ears.

Ye Feng nodded, keeping in mind what Xiao Lao said.

After Xiao Lao finished speaking, he began to refine the elixir, and he was almost done with what he should have said, all that was left was to tell Ye Feng when he started.

Ye Feng looked at the medicine tripod floating in front of Xiao Lao, and he felt that the moment Xiao Lao finished speaking, the temperature increased, because Ye Feng saw that the medicine tripod's arms had all turned fiery red, and there was still hot air coming out.

"Dancheng!" Suddenly, Ye Feng heard Xiao Lao say, and he saw the medicine tripod open, and a small round ball emitting light flew out of the medicine tripod, and then Xiao Lao raised his hand and sucked at the small round ball that flew out, and the small round ball that emitted light was sucked into Xiao Lao's hand.

"Now, this is the Qi Gathering Pill!" Elder Xiao threw the Qi Gathering Pill in his hand at Ye Feng.

Ye Feng hurriedly caught the Qi Gathering Pill that flew towards him, and after catching it, he took a closer look in front of him.

This is a round color, unusually bright elixir, and there is a stripe like a tattoo on the elixir.

"Elder Xiao, why is there a line on this pill?" Ye Feng asked, pointing to the line.

"That's called Dan Pattern, and only when the best pill is refined, will there be Dan Pattern. Xiao Lao said openly.

"Oh!" Ye Feng looked at the stripes, which turned out to be the Dan patterns that only appeared with the best elixir.

"Then Xiao Lao, as long as this Dan pattern appears in a pill, does it mean that it is the best?" Ye Feng asked.

"For the first to third grade of the pill, having a Dan pattern can be regarded as the best, but not for the fourth grade and later, because there may be more than one Dan pattern after the fourth grade. "Among the pills he refined himself, there were not a few that had three, four, or even five or six pill lines.

"Then Xiao Lao, how many Dan lines can appear at most in the pill?" Ye Feng heard Xiao Lao say that there would be more than one Dan pattern in the pill after the fourth grade, so he wanted to know how many could appear at most.

"Nine, the Dan Pattern I know the most is a Nine Pattern Transformation Dragon Pill that I was lucky enough to see. "He'd seen the pill with the most nine lines at the biggest auction in that place before, and it was the pill with the most nine lines he knew.

"Jiujo! a lot!" Ye Feng said secretly surprised, because he heard Xiao Lao say that he was lucky, then he could be sure that Xiao Lao had only met him once, so could he not be surprised.

"That's right, Xiao Lao, does that Dragon Pill really have the effect of turning into a dragon?" Suddenly, Ye Feng remembered what Xiao Lao said.

"Well, it has the effect of turning into a dragon, but it is not a complete dragon, but a dragon's wings, dragon tail, dragon scales and dragon breath, and it only has an effect on demon beasts, but not on people. Xiao Lao said.

Ye Feng nodded, he didn't expect that this Dragon Pill was useless to people at all, he also thought about getting a Dragon Pill in the future, so that he could feel what it was like to turn into a dragon.

"Then Elder Xiao, I'll start refining medicine now?" Ye Feng asked.

"Then let's get started!" Xiao Lao nodded and withdrew the Python Fury Flame from the medicine tripod.

And Yao Ding also fell on a boulder in Xiao Lao's will.

"Elder Xiao, why can't those elixirs fly?" Ye Feng waved at the pile of medicinal materials like Elder Xiao, but unlike Elder Xiao, he could separate the materials with a single wave.

"You can't do the method I just used to get the materials now, you better choose it yourself, besides, you can't do the Fuding refining medicine yet, so you can refine the medicine on that stone!" Xiao Lao said loudly, the actions he made just now required very strong soul power and control before they could be used, and although Ye Feng's soul was strong, he had not yet reached the realm of Fuding alchemy.

"Oh!" Hearing Xiao Lao say that he couldn't do the alchemy action he had just made, he walked to the medicine pile, picked out a refining material, and then came to the boulder where the medicine tripod was.

The height of this boulder is only the height of Ye Feng's belly, it looks like a huge stone platform, and it can also be said to be a small square for one person.

Ye Feng put the elixir in front of him, took a deep breath, then exhaled, stretched out his right hand, and the refining spirit operated, and the yuan power flowed into the evolution of the fire heavenly vein.

"Feng!" A fire appeared on Ye Feng's right hand, it was an orange flame.

"Go to ......"

"Wait!" Just as Ye Feng was about to send the Yuan Fire in his hand into the medicine tripod, Xiao Lao's voice rang out.

"Old Xiao, do you have any other questions?" Ye Feng stopped his movements, turned his head, and looked at Old Xiao.

"Before starting alchemy, I have one last thing to pay attention to to tell you" Xiao Lao remembered, he still had one more point to tell Ye Feng.

"What is it?"

"Because you have just started to learn alchemy, refining elixir requires a kind of seed, you should start with gathering spirit fruits, then quenching grass, absorbing spirit leaves, and finally weaving vines, as for refining elixir at the same time, you have to wait until your alchemy skills are refined. Xiao Lao felt that if Ye Feng had been refining all of them together like him at the beginning, then a material could only be wasted, although it was not a good elixir, but it could not be wasted.

"Oh, okay, I see!" Hearing Xiao Lao's words, Ye Feng answered, turned his head, and took another deep breath.

With a wave of his right hand, the orange flame in his hand rushed out of his hand and burrowed into the medicine pod in front of him.

After Yuan Huo entered the medicine tripod, Ye Feng immediately released his soul power to cover the entire medicine tripod.

He had heard Elder Xiao say that becoming an alchemist required a strong soul power, so that he could always feel the changes in the materials of the pill in Dingnei.

When he felt the fire in the Ding, Ye Feng grabbed the Qi Gathering Fruit with one hand, and his soul power controlled the lid of the Medicine Ding to open, and the Qi Gathering Fruit in his hand was sent to the Medicine Ding, and the Qi Gathering Fruit flew into the Medicine Ding accurately, and then the lid was closed.

After Ye Feng entered the medicine tripod, Ye Feng controlled the firepower and refined it.

Suddenly, a burning smell wafted into Ye Feng's nose.

Ye Feng stopped his movements, opened the medicine tripod, and looked at the pile of black qi gathering fruits in the ding, now it can't be called qi gathering fruit, now it can only be called black charcoal.

He had just increased the fire, and he directly burned the Qi Gathering Fruit into black charcoal.

"If you fail, you will start over, accumulate experience in failure, all alchemists are like this, take out the Qi Gathering Fruit and throw it away, and refine and quench the grass" Xiao Lao also smelled the burnt smell, and there was nothing to sigh for, he had long expected that Ye Feng would fail, because all novices are like this.

"Okay!" Ye Feng has nothing to be frustrated, if he fails, he will start over and accumulate experience.

Use your soul power to take out the residue of the Qi Gathering Fruit, let it flutter in the wind, pick up the quenched grass in your hand, and send it to the medicine ding.

The lid closed, and Ye Feng closed his eyes. This time, Ye Feng did not directly increase the firepower, but heated up little by little, and found a point suitable for refining and quenching grass.

Refining the elixir, if the fire is big, it will directly burn the elixir, and if the fire is small, it can't be refined, and Ye Feng can't directly increase it, so he is slowly increasing it now, and the elixir power feels the changes in the quenching grass in the fire.
