Several people stared at the Dan furnace in Chen Feng's hand, as if they had noticed something unusual.

"That kid is using ...... Purple Furnace?"

The Wind and Snow Sect Sect Master wiped his eyes and said in disbelief.

"This, how is it possible, the Ziyun Furnace is that guy's treasure, it has never left his body, how can it be in his hands, this is absolutely impossible. ”

Ma Hao, the master of the Sword Pavilion, was also incredible.

"Judging from the situation at this time, it must be the Ziyun Furnace, interesting, no wonder this son can refine the five-grade pill, it is because of that old guy. ”

Qianfengzi's eyes flickered, as if he was thinking about something, and muttered.

"The old fellow hadn't seen him for hundreds of years, and I thought he had fallen, but in this way, he was still alive and well...... I'm afraid this kid's origin is not simple. ”

Shangguan Renjie stared at Chen Feng, his eyes flashing with a blurry light, and sighed lightly, not knowing what he was thinking.

No one knew about the conversation between these powerful people, and the competition on the field at this time also caused a small sensation because of the difference of Chen Fengdan's furnace, but it didn't take long for it to calm down again.

All the Tianjiao who participated in the competition had already sacrificed the Danhuo, revealing their true strength in the Dan Dao.

The light of various colors of Dan Fire flickered, and the field immediately became exciting.

Chen Feng's Dan furnace here also began to change, and the purple color of the whole body had already revealed a trace of demonic red under the high temperature of the Dan Fire.

As time passed, those purple mist continued to pour out of the Dan furnace, already enveloping the place where Chen Feng was, and gradually, everyone could no longer see his figure, and could only hear the roar of the fierce beast from time to time.

"The materials needed to break the Erdan are not ordinary. Chen Feng looked at the mountains of medicinal herbs he took out, and couldn't help but pout.

After seeing the color of the Nadan furnace change again, he took some medicinal herbs and put them into it, and the high temperature dispersed, instantly turning the medicinal herbs into clouds.

Alchemy extracts the essence of the medicinal materials, that is, the clouds that can be seen, and when all the medicinal materials are turned into clouds, the temperature in the Dan furnace changes, so that the essence of various medicinal materials can be condensed, and finally it can become an elixir!

In a moment, Chen Feng added some medicinal materials to it, and in this way, while carefully controlling the temperature of the fire, he continued to put in the medicinal materials according to the needs of the Dan Fang.

When Chen Feng really used this Purple Yun Furnace for the first time, he knew the power of this Purple Yun Furnace, those purple clouds and mist that shrouded the surroundings were actually similar to the Great Spirit Gathering Array, and they could actually gather the surrounding spiritual energy, making the essence of these medicinal materials extracted more refined and effective.

As for the carvings of those demon beasts on the body of the Dan furnace, they were even more wonderful, but as Chen Feng injected spiritual power and Dan Fire, they would surge even more fiercely.

Their surge seemed to contain a strange power, and each surge could speed up the speed at which Chen Feng could extract the essence of medicinal herbs.

In other words, it can increase the speed of alchemy.

And those demon beasts are different, so they have their own effects, such as the demon with a red body, it can emit a scorching aura, making Chen Feng's Dan Fire even stronger.

Every time it roared, it would raise the temperature of the Dan furnace by a single level, and these changes could actually be controlled by the alchemists!

"This Dan furnace...... I'm afraid it's not easy. Chen Feng was shocked by the strange power of his Dan furnace, and muttered to himself at this time, thinking of Wang Yunfei.

At that time, Chen Feng asked about the origin of this Dan furnace, but Wang Yunfei only passed by perfunctorily and did not say anything.

Now judging from the power of this Dan furnace, I am afraid that Wang Yunfei is deliberately hiding something, just by relying on this demon beast that only exists in ancient times, it can be sure that this Dan furnace has a great origin.

Kirin, Phoenix, Gluttony, Poor Strange!

These are legendary monsters!

"This person must not be as scheming as he seems, but what is he helping himself so for?" Chen Feng frowned slightly.

......

Just as Chen Feng was meditating on the alchemy, he was above a deserted island on the continent.

Suddenly, the dark clouds surged, gradually turning into a curtain of light, and then a scene of Chen Feng sacrificing the Purple Yun Furnace Alchemy appeared from it.

In the depths of the underground of this isolated island, there was an embarrassed white-haired old man who was originally sitting cross-legged with his head bowed.

In an instant, he suddenly raised his head, and an incomparably strong essence flashed in his blood-red eyes, and he looked at Chen Feng in the void light curtain.

"Little guy, the old man gave you all this thing, don't let the old man down!"

The old man muttered, and suddenly, a divine thunder descended, directly shattering the light curtain that revealed the figure, and then fell, bombarding this isolated island.

The earth-shattering roar immediately came from inside the desert island, but when I saw the old man's surroundings, countless purple thunderbolts immediately appeared, blasting towards the old man as if they were killed.

At this moment, the old man suddenly laughed wildly, and madness flashed in his blood-red eyes.

In an instant, a breath that shocked the heavens and the earth emanated from his body, turning into invisible forces that collided with those thunders and lightning!

"Hahaha, it's been three hundred years, you can't help me for three hundred years, and you can't do it now!"

In an instant, the roar was monstrous, the island shook, and the sea roared!

In the void, there was no response, only the thunder and lightning that continued to land with a bang!

It was like the destruction of the world, going straight to the isolated island, and then the laughter was even crazier, almost roaring!

This scene was earth-shattering, but no one saw it.

......

Time has passed, half a day has passed, the Dan fire in the square is still the same, for this big competition, everyone has done their best, so the quality of the pills they have refined is high, and there is no Dan incense floating out at this time.

Especially Chen Feng, Sima Yun, Liu Ning, Hou Qiuge, Na Chu Xuan and Hu Qiang, as well as several other Tianjiao, were still putting medicinal materials into the Dan furnace.

Even though these people are all Tianjiao of various sects, under such a great consumption, beads of sweat appeared on their faces, and their expressions also showed exhaustion.

"These guys, as expected, are not fuel-efficient lamps, and the quality of the pill this time is probably more than five grades. ”

Chen Feng glanced around indifferently, muttering in his heart, this sweep, but he saw the provocative eyes cast by Chu Xuan not far away.

Chen Feng smiled, ignored it, and then concentrated on alchemy!

"Hmph, you're really a guy who doesn't know the height of the sky! I'll kill you this time. Seeing that Chen Feng didn't take care of himself, Chu Xuan snorted coldly.

Hou Qiu, who was not far away, also swept his eyes, glanced at Chen Feng indifferently, and flashed a trace of murderous intent.

This scene was noticed by Liu Ning and Sima Yun, and the two were slightly stunned, and then they talked!

Time passed, another hour passed, at this time, Chen Feng finally put the last medicinal materials into the Dan furnace, Chen Feng took a deep breath, and more concentrated on controlling the temperature of the Dan furnace.

Purification, fusion, and chemical Dan, Chen Feng completed the first step, the basic part, and the next part is the most important and difficult part!
