The cooperation between the old and the young is quite tacit, and those who don't know may still think that the two are in a master-apprentice relationship! Time passed quietly like this, and the medicinal materials on the greenstone were also refined by Yan Fei.

"It's worthy of a different fire, if this is refined by using other flames, I don't know how much time it will take! Moreover, the medicinal materials refined by the different fire, its medicinal liquid appears to be more pure, which will be more conducive to the subsequent fusion of the pill. The old man Jiuyan looked at the small green bottles held on the platform not far in front of him, and said with a slight sigh.

Although Yan Fei was refining with the Five Strange Fires, there were thousands of medicinal materials needed to refine the Nine Flames Breaking Emperor Pill, and there were some medicinal materials that were extremely difficult to refine, so it took a day and a night to refine the medicinal materials.

Looking at the small pile of medicinal materials left on the platform, the old man Jiuyan squinted slightly, and then muttered, "The remaining medicinal materials will be handed over to the old man!"

As he spoke, the old man of Jiuyan swept in the air, and the old wrinkled palm lightly touched the small pile of medicinal herbs, and then, as if they were possessed by some force, they flew into the air one after another.

"Boy, although there are many different fires, if I were you, I would only use one kind of different fire to refine medicinal materials! Only one kind of flame is needed, and the thoughts are divided into hundreds or thousands of strands, and each thought can be controlled and refined by a wisp of flame. ”

The old man Jiuyan saw that Yan Fei had just successfully refined the medicinal herbs in his hand, so he hurriedly moved his hand and threw the remaining medicinal herbs into the air.

Then, the old man Jiuyan's eyes narrowed slightly, his hands stretched out flatly, and then two rays of fire shot out from his body.

Seeing the flame in the old man Jiuyan's hand, Yan Fei was immediately shocked, and the strange fires such as the Ice Ancestral Fire on the side were also stunned, because the moment the old man Jiuyan took out the flame, they all felt a familiar aura, this kind of breath, the only strange fire between heaven and earth can emanate.

"I didn't expect that Old Man Jiuyan also had a strange fire in his hands, since this is the case?

As soon as such doubts flashed in his heart, he suddenly dissipated, because at this moment, Yan Fei was completely attracted by the old man Jiuyan's method of refining medicinal materials.

I saw two rays of fire that shot out from the hands of the old man Jiuyan, and suddenly one trembled, and then turned two into four, and four into eight...... Until the end, it turned into hundreds of flames and threw itself into the air, and there was a medicinal herb floating above each fire, at this time, those medicinal herbs were undergoing great changes under the burning of the fire, and those useless impurities were directly eliminated, leaving only the most essential part of the medicinal herb itself.

"This Jiuyan Old Man's alchemy ability is really terrifying, although I can also divide my mind into hundreds of strands, but in this way, I have to spend more tremendous spiritual power to control it! Maybe it's not too much of a problem to control dozens of strands of mind, but if it's hundreds?" Thinking about it, Yan Fei sighed and shook his head, you must know that the medicinal materials that were taken into the air by the old man of Jiuyan were not the same as the temperature of the flame, this is not all incinerated according to the unified standard, it can be seen that the ability of the old man of Jiuyan on top of the alchemy is so terrifying. And in his spare time, the old man Jiuyan will also give a few words of teaching, which shows how powerful this seemingly ordinary old man is in alchemy.

With the addition of Old Man Jiuyan, the last batch of medicinal materials were all refined smoothly, and the hundreds of green bottles were also filled with various refined medicinal liquids.

The old man Jiuyan stared at Yan Fei, and found that the latter was also looking at him at this moment, and from Yan Fei's eyes, the old man Jiuyan saw where his doubts were.

"My strange flame is called the Nine Heavens Flame of the Sun, and it has a lot to do with the nine rounds of the Sun that you see in the outside world. Are you kid wondering, why do I need your help when I have a strange fire?"

Yan Fei nodded slightly, this was really the most doubtful place that was haunting his heart now. And the bloodthirsty flames and other strange fires around Yan Fei were stunned one by one, although they were also different fires, they had never heard of the Nine Heavens Flame Yang Flame.

"This world is too big, it's not strange that we don't know the Nine Heavens Scorching Sun, just like the birth of the flame, who of you can predict it? The strange fire list you are on is just a corner view, this world is far from being able to be summarized by a different fire temple in the God of War Continent. Ice Shadow Ancestral Fire said with a slight sigh, and as he said this, the Bloodthirsty Flame and other strange fires around him nodded one after another, thinking that they also agreed with what Ice Shadow Ancestral Fire said.

"Little guy, that Nine Yan Breaking Emperor Pill is not so easy to refine, do you know why this pill is called Nine Yan Breaking Emperor Pill?" The old man of Jiuyan looked at Yan Fei and asked, as if he knew that Yan Fei would shake his head, so this old guy continued at the moment when Yan Fei just shook his head: "The refining of the Nine Flame Breaking Emperor Pill is actually not complicated, and the pill refined by these thousands of medicinal materials is not too difficult for some alchemy masters at all. But throughout the ages, there have been very few people who have refined the Nine Flame Breaking Emperor Pill, do you know why?"

Yan Fei shook his head again, he had never even heard the name of the Nine Yan Breaking Emperor Pill before, how could he know these secrets?

"Hehe! To refine the Nine Flames Breaking Emperor Pill, the most important link is that when melting the Pill, the combined force of the nine different fires is needed, and only the pill that has been tempered by the nine different fires can be called the Nine Flames Breaking Emperor Pill. Speaking of this, the old man Jiuyan suddenly burst out laughing.

"Nine kinds of different fires! This is not a small number, a rare different fire on weekdays, when refining this Nine Flame Breaking Emperor Pill, it actually needs nine kinds, which is too difficult for ordinary alchemists to refine the Nine Flame Breaking Emperor Pill. ”

"Senior Jiuyan, there are only five different fires on my side, and there are only six different fires on your side, and the nine different fires in the distance are still three miles away!" Yan Fei opened his mouth and asked, just as the old man Jiuyan said, even if the strange fires on their side were added up, they would not be enough! Even if the unrefined Heavenly Netherworld Ghost Fire in Yan Fei's body was counted, it was only seven different fires.

"You kid is quite honest!Old man of Jiuyan Breaking Emperor Pill, I don't have that luxury, but it's not impossible to refine a Five Yan and Six Yan Breaking Emperor Pill!" said the old man Jiuyan with a squint and a smile.

Yan Fei on the side was slightly surprised, and muttered, "Is this okay?"
