Both of their faces received special care from the bottom of the pot to varying degrees, staining their faces with mottled black stains, like two miners who had just finished digging coal.

"The steps and weights are strictly in accordance with the records on the Ten Fang Dan, and there should be no mistakes, so the problem must be in the control of the furnace fire!"

Zhao Buyu shook his head in frustration, his mood was very low, and he didn't care about the ash on his face, he had never felt such a failure, he had tried more than 100 times before and after, but the result was still the same, it was still a halfway fryer, and occasionally there was a situation where the fryer was not fried, but it was also Cheng Dan's failure, refining a furnace of scorched waste slag.

"Third child, don't be discouraged, don't be impatient in alchemy, your mentality is a little unstable, adjust it first, let's try again!"

Xu Yuan was also a little excited, and handed over a spirit stone as he spoke!

No one wants to see failure, but no one can avoid failure! Even alchemy wizards dare not guarantee that they will succeed every time, and summing up experience is the only way to succeed.

Zhao Buyu nodded, put on a new Ding furnace, took the spirit stone in Xu Yuan's hand, sat on the futon and began to slowly exercise, absorbing the spiritual energy contained in the spiritual stone and replenishing the spiritual energy consumed by himself.

Xu Yuan stayed aside and didn't make a sound, only silently began to prepare a small portion of all the blood of the alien beast, and then divided a small portion of the elixir that Zhao Buyu used just now for backup, and then began to seriously look through the book of Ten Fang Dan.

After a long time, Zhao Buyu let out a sigh of relief and slowly stood up from the ground.

"Landlord, I'm ready!"

Xu Yuan nodded slightly, "This time, I'll control the fire, and you will grasp the timing of the medicine!"

"Are you sure?"

Zhao Buyu still can't believe it, fire control is a very critical step, it can be said that the reason for whether or not to become Dan is sixty percent due to the control of fire, Zhao Buyu is confident that although his understanding of Dan Dao is shallow, it is much better than Xu Yuan.

"Don't worry, you just have to see the timing!"

Xu Yuan watched Zhao Buyu's movements carefully on the side just now, he alone had to control the flame and see the right time to add various materials into the Ding furnace, it was indeed not easy, and it was easy to be distracted, so Xu Yuan proposed to control the fire himself.

It is not difficult for Xu Yuan to transform his aura into flames, as long as he gently outputs his aura, uses aura to support the burning of flames, and always maintains the intensity of burning at a relatively balanced level, he believes that Cheng Dan is not hopeless.

You must know that Xu Yuan's realm is much higher than Zhao Buyu, and the reserves of spiritual energy are also more, which can be maintained for a longer time.

Zhao Buyu was helpless, although he didn't have confidence in Xu Yuan, but he was the landlord, so he could only nod and agree.

"Okay, cheer up, what's your expression?

Xu Yuan glanced at Zhao Buyu, who was full of sluggishness and lifelessness, scolded angrily and funny, and began to adjust the position of the Ding furnace by himself, holding his hands against the fire at the bottom of the Ding furnace, and then began to suddenly urge the aura of his inner mansion to help burn, intending to preheat the Ding furnace first.

However, due to habitual movements, Xu Yuan's aura did not immediately urge his palm, but fiercely jumped into the sea of knowledge, which caused the resonance of that spade card.

Xu Yuan was startled, and secretly said that he was going to suffer! Hurriedly withdrew his aura, preparing to gather it into his palm, but something unexpected happened to Xu Yuan,

The aura was indeed very honest in carrying out Xu Yuan's intentions, but when he retreated, it seemed like a robbery, and he actually swept away the aura contained in a large black card.

A purple-black mist mixed with Xu Yuan's aura was gathered in the palm of his palm.

Xu Yuan had the intention to stop it, but it was too late, and the purple-black aura mixed with it erupted from Xu Yuan's Zhang Xin, and instantly merged into the fire.

"Poof!"

The flame was stimulated, made a soft sound, and swayed fiercely, and the color of the flame instantly turned black.

Xu Yuan's complexion changed, and he clearly felt that this strange flame seemed to be hotter than Zhao Buyu's flame before, and the scorching made his cheeks ache, as if his entire face was about to be roasted and exploded.

However, this is not over, stimulated by the purple-black mist, the flames seem to be alive and jump higher and higher, and have already wrapped most of the entire Ding Furnace, as if they want to swallow the entire Ding Furnace.

Then, Xu Yuan only felt a stinging pain in the inner mansion, and the aura was rapidly consuming!

"This ......"

Zhao Buyu stood aside in a daze, "This is too fierce, is it going to roast the Ding furnace together?"

"Why don't you start soon?"

After a while, Xu Yuan's forehead began to squeeze out beads of sweat the size of beans, and he felt that he couldn't support it for long, and he was in a hurry, as if he was urging his life, and yelled at Zhao Buyu who was in a daze.

"Oh, yes! right now!"

Surprised by this, Zhao Buyu reacted at this time, his task was to watch the Ding Furnace throw medicine and alchemy!

Zhao Buyu saw that it had been warmed up, and quickly poured a bowl of alien beast essence blood that had been prepared into the furnace, and his expression became extremely serious again, this time he was only responsible for administering the medicine, and he couldn't make a mistake like before.

"Green wolf blood, chicken heart grass, black snake ......"

Zhao Buyu had words in his mouth, and the materials in his hands were put into order one by one, and his movements were light and skillful, without the slightest drag, for fear that something would go wrong.

Alchemy is a very rigorous thing, whether it is fire control or the number of materials, the order of delivery, or even the timing, it must be appropriate, not more, not less, otherwise any slight deviation may lead to refining failure, which is too frustrating.

There are all kinds of materials for a pill, but it is not so easy to get together, if the refining fails, and there is no harvest after working hard for a long time, not to mention the loss of material money.

The sweat on Xu Yuan's face rolled down, and the inner house had changed from a stinging pain to a labor pain, this was a phenomenon of lack of strength after the aura, Xu Yuan had no choice but to resist, his eyes were staring at the furnace tightly, one hand was tightly against the Ding furnace, slightly adjusting the urgency of the aura output, and the other hand had already touched into his arms, took out a spiritual stone, and tightened my hand again, ready to replenish the aura at any time.

"Poof!"

The flames swayed suddenly, and gradually began to decrease, Xu Yuan was in a hurry, and he couldn't care about replenishing the aura, and his other hand also touched the other side of the Ding furnace, increasing the output of the aura again.

"Boom!"

Suddenly, Xu Yuan's inner mansion seemed to sound an explosion, Xu Yuan was startled, and suddenly found that his aura began to be abundant again, and hurriedly used his spiritual sense to investigate the inner mansion.

How is it possible! The spirit stones haven't even had time to be used, what is the matter with this sudden burst of aura.

After some investigation, Xu Yuan discovered that the aura was gushing out from the bean-sized particles hanging in the inner mansion, and the purity of the aura surprised Xu Yuan himself.

He always thought it was a stone!!

"Hurry! It's now!"

Under the action of steam, the lid of the Ding furnace began to jump, making a jingling sound, Xu Yuan roared fiercely, it has successfully reached the finishing stage, this is the critical period of Cheng Dan, can Dan be achieved at this moment.

Zhao Buyu was not ambiguous, grabbed the lid of the Ding furnace, threw the only remaining handful of medicinal materials in his hand into the Dan furnace, and then pressed the lid down.

"Give it to me!"

"Bang!"

The lid shattered under Zhao Buyu's vigorous suppression and the continuous impact of steam, and the violent steam rose straight up, and there was a white pill faintly in the steam.

"It's finished?"

Zhao Buyu was overjoyed in his heart, reached out his hand, grabbed the white pill in his hand, and his eyes widened!
