The process of alchemy is boring and complicated, there are no less than dozens of foil herbs just thrown, and after the careful screening of the old man of Baicao, the time of fusion is much longer than just now.

Moreover, in order to increase the chance of alchemy, the old man of Baicao also sent some soul power into the Dan furnace, which will cause some damage to the old man of Baicao.

But this is also harmless for the old man Baicao, after all, Ye Feng is the son of an old friend, and it is worth paying a little for him.

Ye Feng could clearly feel the intention of the old man Baicao to refine the pill, and he did not reveal the slightest emotion at the moment, but put this friendship in the bottom of his heart, and when he cultivated and increased in the future, he was bound to make a move to repay his kindness, this is Ye Feng's character, and he will repay his kindness.

The passage of time passed quietly at his fingertips, and it took two hours just to refine the foil herb of the Resurrection Purple Pill, and then it went through several times of compression and condensation, and then carefully screened, leaving less than one-third of the medicinal liquid.

When this step was completed, the old man of Baicao exhaled softly, but without the slightest stagnation, he placed the inner pill of the Ice and Fire Grass and the Heavenly Demon Poison Demon Beast in the Dan furnace!

Ice and Fire Grass is a mysterious herb produced by the fusion of the two powers of ice and fire, which has the same origin as Ice and Fire Hanyan, but the medicinal effect is too strong to be swallowed, and only by neutralizing it with mild herbs can it achieve a perfect effect.

The Inner Dan of the Heavenly Demon Poison Demon Beast is even more weird, the combination of the two races of demons and demons, the mysterious species produced, the same nature as the Ice and Fire Grass, the fusion of the two will give birth to a strange medicinal effect.

Ye Feng's breathing was a little short, it was extremely difficult to obtain these two heavenly and earthly treasures, and he knew very little about their abilities, but now observing the alchemy, he deeply felt the restraint effect of these two powers on the power of the soul, and at this moment, the old man of Baicao was also suffering.

The old man's face was much more solemn than just now, and it could also be seen from this that refining this kind of pill was very different from the soul pill just now, and the soul power consumed alone had increased several times.

However, at this moment, the old man of Baicao could still easily deal with it, and when the Mulan Fire drifted to the bottom of the furnace, he instilled a lot of Yuan Force, which stimulated the flame of the Mulan Fire and began to refine rapidly.

The Ice and Fire Grass was much easier than the Inner Dan of the Heavenly Demon Poison Demon Beast, but it still took a lot of effort, and it was not until the end that it turned into a liquid with two colors, one blue and one red.

However, the Inner Pill of the Heavenly Demon Poison Demon Beast was too hard, not only urging the Yuan Force to increase the Mulan flame, but there was still no sign of melting, and at this time, the old man's expression began to look ugly, after Ye Feng saw it, he wanted to make a move, but he was always afraid that it would delay the alchemy process of the old man.

"Boy, hurry up and refine your molten geocentric flame sacrifice, you and I will join forces to refine the inner dan of the Heavenly Demon Poison Demon Beast!"

A layer of cold sweat appeared on the forehead of the old man of Baicao, and he spoke a little anxiously in a nervous state, Ye Feng heard this, and without the slightest hesitation, he summoned the molten geocentritis from his body, and urged the Yuan Force to quickly convey it towards the Baicao Dan furnace!

With the help of the molten geocentritis, the load of the old man of Baicao was reduced by half, and there was less of a great obstacle to refining the pill, and Ye Feng's molten geocentric inflammation was slightly stronger than the power of the Mulan fire, and in just one short hour, the inner pill of the Heavenly Demon Poison Demon Beast was completely melted!

Looking at the drops of dark green liquid, a touch of joy appeared on the face of the old man Baicao, and he immediately took this opportunity to adjust his breath to fuse the various colored liquids.

The color properties of these liquids are different, and it is also very troublesome to fuse, and even due to some unstable factors, the phenomenon of the fryer will appear, and this is the last and most critical step!

As long as these liquids are completely fused, most of the pills will be successful, even the old man of Baicao's breathing can't help but become slightly short, he endured the throbbing in his heart, and began to fuse these liquids in the safest posture, but as soon as several medicinal liquids came into contact, there was a strong rejection phenomenon!

When the repulsion phenomenon appeared, the old man's brows furrowed even tighter, and at the moment, a small amount of soul power was separated again and transported to the Dan furnace, with the blessing of these soul powers, the repulsion phenomenon was reduced a little, but it was still extremely unstable, as if it would suddenly explode in a moment!

The old man of Baicao thought for a moment, wanting to greatly increase the success rate of the elixir, the first time he refined an elixir of this grade, he was a little inexperienced, and it was this kind of elixir with opposite yin and yang attributes.

But that doesn't make excuses, and the old man has found a way through the various thoughts that have crossed his mind.

This method is a bit dangerous, but it is harmless to the elixir, and that is to use the power of one's mind to forcibly manipulate the fusion of the elixir!

Thinking of this, the old man of Baicao began to act, which urged the power of the mind to try to manipulate the medicinal liquid of various attributes.

However, for the first time, the mental power of the old man was stimulated by the medicinal liquid, and as soon as he was immersed in it, it was rebounded, until he tried more than a dozen times tirelessly, and there was some success!

However, using the power of the mind to manipulate the fusion of the liquid medicine is slower than the ordinary method, although the safety rate is greatly increased, but once the time consumed is too long, the elixir will inevitably be directly discarded!

Therefore, the old man Baicao was a little anxious, and his mind was constantly urging, which led to a significant decline in his cultivation, but he did not give up in the slightest, but became more and more courageous the more he fought, and at this moment he gave full play to his lifelong alchemy skills.

"Bang!"

With a crisp sound, these medicinal liquids with various powers finally fused perfectly, and when this scene appeared, a touch of ecstasy appeared on the face of the old man of Baicao!

This is the most difficult step, but if it is crossed, the pill will be considered to be half successful, so he can't help but be unhappy!

Ye Feng used the power of his soul to spy on the changes in the Dan Furnace, and he was also very awake for this Furnace Pill, looking at the eyes of the old man Baicao with a deep sense of gratitude, this time, he only needed to wait for a while, and the Purple Pill of the Soul could be truly successful!

With the Resurrection Purple Pill, he has the qualifications to cultivate the Ice, Fire, and Cold Flames, and there is a constant connection between the two, Ye Feng knows the key point in it, he is waiting, waiting patiently!

The old man of Baicao did not dare to be distracted in the slightest, and even when the Dan furnace was shaking, he was not moved in the slightest, he had already devoted himself to the wonderful process of alchemy at the moment, painful and enjoyable.
