Several people stared at the Dan furnace in Su Chuan'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 Su Chuan, his eyes flashed with a blurred 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 Su Chuandan'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.

The Dan furnace here in Su Chuan has also begun to change, and the purple color of the whole body has revealed a trace of demonic red under the high temperature of the Dan fire.

As time passed, those purple mist poured out of the Dan furnace in a steady stream, covering the place where Su Chuan was, and gradually, everyone could no longer see his figure, and could only hear the roar of the fierce beast that came out of it from time to time.

"The materials needed to break the Erdan are not ordinary. Su Chuan looked at the mountains of medicinal materials 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, Su Chuan 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 Su Chuan 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 Gathering Spirit Array, and they could actually gather the surrounding spiritual energy, making the extracted essence of these medicinal materials more refined and more effective.

As for the carvings of those demon beasts on the body of the Dan furnace, they are even more wonderful, but with the injection of spiritual power and Dan fire into Su Chuan, they will surge even more fiercely.

Their surge seemed to contain a strange power, and each surge could speed up the speed at which Su Chuan extracted 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 functions, such as the demon with a red body, which can exude a scorching aura, making Su Chuan's Dan Huo 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. Su Chuan was shocked by the strange power of his Dan furnace, and muttered to himself at this time, thinking of Wang Yunfei.

At that time, Su Chuan asked about the origin of this Dan furnace, but Wang Yunfei only passed it by 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 doing so much to help himself?" Su Chuan frowned slightly.

......

Just as Su Chuan was pondering for alchemy, he was above a deserted island on the continent.

Suddenly, the dark clouds surged, and gradually turned into a curtain of light, and then there was a scene of Su Chuan sacrificing the Purple Yun Furnace Alchemy.

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 Su Chuan 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 Su Chuan, 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. ”

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

Su Chuan 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 Su Chuan didn't take care of himself, Chu Xuan snorted coldly.

Hou Qiu, who was not far away, also swept his eyes, glanced at Su Chuan 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, Su Chuan finally put the last medicinal materials into the Dan furnace, Su Chuan took a deep breath, and more concentrated on controlling the temperature of the Dan furnace.

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