There are many kinds of medicinal herbs in the medicine field, and they are not planted according to too many rules, and most of them are densely mixed together with several different medicinal herbs.

Step-by-step alchemy is too time-consuming.

Ji Yan hesitated for a moment, decisively abandoned the pill formula, and started an alchemy method that almost no one had tried - what to refine......

What medicinal herbs are growing in front of her, she grabs what medicinal herbs to refine, and there is no pattern at all.

At first, she put in only ten different materials, sat on the floor, and felt the changes in the medicine in the Dan furnace.

Because it is out of the norm, this change seems extremely strange and chaotic at the beginning. As soon as the medicinal herbs melted, the ten medicinal properties exploded, resulting in a violent rejection.

Ji Yan's mind was put into the furnace to feel and control the reaction of the Dan furnace.

In her mind, it was as if dozens of iron balls of different sizes were constantly colliding, some of them fused together as soon as they came into contact and became a new substance, while others were violently repulsed and erupted into very strong fluctuations.

Ji Yan used his mental power to suppress all the fluctuations in the Dan furnace, and if this uncontrollable internal force was not vented, it would constantly impact the reactions in the Dan furnace!

Under the effect of this impact, the medicine in the Dan furnace will accelerate the fusion or rejection, and then cause more intense fluctuations!

Gradually, the reaction in the furnace became more and more intense, hundreds of times beyond the ordinary alchemy time. Weak or even useless medicinal properties will be destroyed little by little in this impact, and what remains is a stronger and purer substance.

In a short time, the reaction in the Dan furnace reached the peak level, and the original dozens of substances in Ji Yan's mind had already turned into the last two unfamiliar medicinal properties, and they were violently impacting!

The pressure in the Dan furnace was so strong that it was difficult to control, and the lid of the furnace was also frequently jumped by the impact, and the energy overflowed.

In the dark night, I could vaguely see a strong light shooting out of the Dan furnace, as if a round of scorching sun was trapped inside!

If it weren't for the medicine boys in the vicinity, someone would have noticed that there was a spot in the darkness that was shining like thunder!

After a long time, Ji Yan raised his right hand and slapped it towards the Dan furnace, and then only heard a rumbling sound like thunder from the Dan furnace, Ji Yan's eyes lit up, and the refining was finally completed.

Based on the fact that he didn't know what he was refining, poisonous or non-toxic, Ji Yan put the Dan furnace on the ground very carefully, and he stepped back ten meters before opening the Dan furnace in the air with a wave of his hand.

A colored smoke accompanied by a faint glow came out of the Dan furnace, and disappeared into the air in an instant, and then several things in the furnace that looked like mud pills fell into Ji Yan's eyes.

Ji Yan held his breath, walked over cautiously, and took out a silver needle and pricked it, and found that it didn't seem to be poisonous.

picked up one and looked at it carefully, Ji Yan was instantly disappointed.

All the medicinal properties in this pill are gone, and all you get is a mess of impurities!

"What's going on?"

When the alchemy was about to end, Ji Yan obviously felt that there was still a medicinal property in the furnace reacting......

After pouring out the mud pill, Ji Yan casually grabbed ten more medicinal herbs and put them into refining.

A similar impact appeared again, Ji Yan mastered some rules, tried to slowly increase his thoughts, and the strong pressure made the reaction speed up, and in a short time, a new furnace, the reaction was completed.

When I opened it, a burst of glow rose, and there were still a bunch of mud pellets in the furnace.
