Although he had expected the difficulty, at the beginning, Gu Fenghua knew that it was much more difficult than he had imagined. Just in an instant, the liquid of Chinese medicine in the furnace began to boil, and the huge force of medicine repelled each other. It was like a basin of ice water suddenly splashed on a red rock, and the whole Dan furnace was shaking.

Thanks to the exquisite refining, high quality and the spirit of artifact, otherwise it would have been smashed by this huge force.

Gu Fenghua where dare to have half careless, desperately hit a handprint. Dan fire then quickly swayed and changed. On the Dan stove, the golden light of the runes also flickered, like gold ribbons, spinning up and down around the Dan stove.

Finally, the red stove gradually calmed down, bursts of more rich, but pure as if there was no impurity in the fragrance of medicine.

Lu Fangyuan sighed for a long time, only to find that his forehead had been covered with a layer of sweat.

Just now, when the Dan furnace was shaking, he was really shocked. He remembered that in Wuji holy heaven, he had invited 15 Saint Dan masters to help him make daokaiyan pill. Three of them failed in the step of integrating herbs, and eleven of them failed in the step of Integrating Medicine. He thought Gu Fenghua would follow their lead and lose the battle in this step, Fortunately, Gu Fenghua didn't disappoint him, and finally succeeded in integrating the drug.

Gu Fenghua himself was also relieved and wiped a cold sweat. Although the quality of these herbs is not high, when the powers of these herbs meet, the power of each other is far more than that of her own. If she really exploded just now, she would not be able to bear it.

Gu Fenghua also knew that even if the herbs of ordinary grade were mixed together, they could produce such terrible medicinal power. It was absolutely not as simple as one plus one equals two. Instead, they could catalyze each other, and their power was ten times, one hundred times or even one thousand times higher. Her understanding of alchemy is deeper.

Dan furnace, liquid medicine is still slowly flowing, forming a vortex. The next step is jiedan, which is the last step, the most important and dangerous step. Gu Fenghua calmed his mind for a while and made a decision again.

Along with the fingerprints, Dan fire fluttered again, and the runes flickered alternately. In the Dan furnace, with the vortex as the center, the medicine juice began to condense.

Gu Fenghua's expression became more dignified.

Although the different powers in the medicine juice have been balanced and recovered, in the process of condensing into Dan, these powers will be highly condensed, further blended, and finally transformed into Dan.

This process is too subtle. Any small accident will lead to the breaking of the balance of power, which will lead to the explosion of the furnace.

And once the highly condensed medicine explodes, its power will be more than 100 times than before. That kind of power don't mention her, even if this has been promoted to the artifact of the demon wood Ding may not bear to live.

Her movements were much slower than before, and every handprint contained all her thoughts. Don't know when, her forehead is already a piece of water, sweat rolling down the cheek.

Lorne's heart hung up. It was not the first time that they saw Gu Fenghua alchemy, but it was the first time that they saw her so dignified.

They finally realized that, even for Gu Fenghua, this Da Dao Kaiyan pill is not so easy to refine.

Although they are not good at alchemy, they are more or less aware that the most critical and dangerous step is to finish alchemy.

From the sweat on Gu Fenghua's face, they can guess how powerful the medicine is. Once it blows up, the consequences will be unimaginable.
