The bald old man felt that his head was running out of stock.

This Chen Feng is really a demon, and the series of techniques used to refine this Songhua Dan have made this senior fifth-level alchemist feel impeccable.

The bald old man had been stagnant at the fifth-level alchemist for hundreds of thousands of years, and although he had not been able to break through the sixth-level alchemist for a long time, his authority over alchemy was even greater than that of an ordinary sixth-level alchemist. Therefore, the Alchemist Guild would rest assured that he would preside over the assessment of the fifth-level alchemist. But people like him even felt unreachable for Chen Feng.

This kind of unattainable is not only Chen Feng's alchemy technique, but also for Chen Feng's courage.

You must know that Songhua Dan is a Nine Heavens Xuanxian level elixir, the effect of the pill can be called against the sky, it can supplement the vitality of the monk, the worst quality, it can also increase the life of a hundred years, the higher the level, the longer the increased life, and even legend, that kind of superb Songhua Dan can even increase the vitality of a thousand years.

Such an anti-heaven effect makes this Songhua Dan one of the most difficult to refine among the Nine Heavens Xuan Immortals. Although the Danfang of this Songhua Dan has always been controlled by the Zhang family, the bald old man clearly knows that even those sixth-level alchemists of the Zhang family are not so easy to refine this Songhua Dan. Even if a few pieces are occasionally refined, most of them are low-grade, and occasionally a medium-grade Songhuadan, the entire Zhang family will be extremely happy.

After all, the life of an immortal is not endless, and the average Da Luo Jin Immortal is only a life of hundreds of thousands of years. Even if it was those Nine Heavens Xuan Immortal, it was only a million years of life. When the oil runs out and the lamp runs out, a high-quality Songhua Dan can provide a buffer for the monk for a while. Perhaps, the monk will be able to make a breakthrough in this additional few hundred years of life and gain an even longer life.

"Chen Feng, although I don't understand where your Songhua Dan Dan Fang came from, just your performance today, the old man has never seen anyone who can compare with you in his lifetime. The bald old man muttered, and then, his eyes suddenly sharpened: "Perhaps, you may be able to reach the seven-star assessment!"

Thinking of this, the bald old man suddenly shot an immortal yuan towards the memory fairy crystal, and in an instant, the memory fairy crystal suddenly became more agile, and the image hidden on the memory fairy crystal was also clearer and more real.

"Several, let's work together to let the Memory Immortal Crystal record all the fluctuations and aura of Chen Feng's alchemy as much as possible!" the bald old man said in a deep voice.

The other three all nodded solemnly, they also saw that Chen Feng was extraordinary, so they all sent immortal yuan towards the memory immortal crystal.

The Memory Immortal Crystal was even more agile, and every inch of Chen Feng's breath was recorded by the Memory Immortal Crystal as it was.

At this time, Chen Feng didn't know what the four old men were doing, he was already completely immersed in the refining of Songhua Dan.

The Dan prescription of Songhua Dan is naturally derived from the inheritance of Taiqing Daode Tianzun. The most immortal Dan Dao ancestor, Taiqing Dao Dao Tianzun created a lot of Dan Fang, and this Songhua Dan was one of them, which was naturally read by Chen Feng. Even, the Songhua Dan Fang read by Chen Feng is much more advanced than the Dan Fang owned by the Zhang family in some places.

With Chen Feng's current Dan Dao level, he is not sure that he can refine Songhua Dan. If it weren't for Zhang Chu's difficulty, Chen Feng originally planned to refine a slightly inferior elixir, that kind of elixir, Chen Feng's grasp was greater, if there was no mistake, Chen Feng would be ninety percent sure of practicing it.

In the alchemy world, ninety percent certainty is already against the sky.

It's just that Zhang Chu's difficulties made Chen Feng have to refine Songhua Dan, a pill that he can't grasp. However, Chen Feng is not afraid of trouble, since he can't avoid it, he will do his best.

At this moment, Chen Feng was in an ethereal realm, playing one fire control battle after another, while deducing the follow-up steps. He tried his best to be able to deduce that step to perfection when he reached that step, and only in this way could he be sure to rush his evaluation to the level of seven stars.

That Ten Thousand Ancient Dan Domain was the Dan Dao World opened up by Taiqing Dao Tianzun, and Chen Feng also wanted to go and see it.

Time passed bit by bit, and the confidence in Chen Feng's heart became stronger and stronger. With the blessing of his powerful Dan Dao background, Chen Feng's previous movements were perfect, even if there were small flaws, they were those insignificant small flaws, which had no impact on the overall situation.

Not far away, the four judges led by the bald old man were already immersed in Chen Feng's alchemy scene at this moment. Chen Feng's every move will make them feel as if they have discovered a new continent and let them linger. Even, some of their original doubts gradually became clear in the process of watching Chen Feng's refining of the pill.

Suddenly, the brows of the four moved slightly, and a sudden tension rose in their eyes. I saw that Chen Feng's movements were constantly slowing down, and the rhythm of the flames in the Dan furnace became more and more profound.

"Is it possible, you are going to become a Dan?" The bald old man didn't dare to blink his eyes, for fear that he would miss the most exciting part in the blink of an eye. However, the next moment, he said softly: "Huh?"

I saw that Chen Feng's movements that had just slowed down suddenly accelerated again, but this time, he found that a stream of emerald green energy poured out of Chen Feng's body, and with the continuous hand-to-hand duel of his hands, it poured into the Tiandan Ding.

"What kind of energy is this, such a powerful life fluctuation, could it be ......" The bald old man suddenly stood up from his chair, his eyes widened, as if he had seen something amazing: "It turned out to be the life force!"

Chen Feng's eyes were deep, and the small saplings in the dantian continued to release the power of life, and with the continuous fighting, today's Tiandanding converged towards the Songhua Dan that was taking shape in the Dan furnace, and then under the control of Chen Feng, it merged with it, and the water melted.

Chen Feng is doing a bold experiment. Songhua Dan is originally to increase vitality, so can he also take the initiative to incorporate some life force to make the medicinal effect of the pill more powerful? Thinking of this possibility, Chen Feng boldly began to try. The power of life was constantly refined into Songhua Dan by him, and it was melted with water, regardless of each other.

In this way, another stick of incense passed, and Chen Feng's heart suddenly moved. In just a moment, Chen Feng clearly captured that Songhuadan had absorbed a large amount of life force, and it was already saturated at this moment. And at this moment, Songhuadan is also completely formed!

"It's time to come out of Dan!" Chen Feng's eyes suddenly bloomed with two divine lights, and a strong self-confidence suddenly released from his body.
