With the passage of time, soon, the condensing grass also turned into a pale green liquid, and in a burst of incineration, the impurities in it also continued to emerge, and then they were driven out by the old man one by one.

Like the red lotus mushroom before, when the pale green liquid shrank to about the size of a thumb, the old man stopped burning and shot it into another small jade bottle on the table next to him.

It seems that because the first few things are to be shown to Mengfeng for careful viewing, the old man's speed is relatively slow. And then it seems that because the old man no longer feels that he needs to look at Mengfeng so carefully, the speed of refining is getting faster and faster.

A medicinal herb that had been refined in a few minutes turned into two or three minutes at this time, then another minute, and finally half a minute.

As the speed accelerated, there were fewer and fewer medicinal materials on the bed, and among the dozen or so small jade bottles on the table next to him, all of them contained the essence extracted from the medicinal materials.

"The refining of medicinal materials is like this, and the next step is an extremely critical step in refining medicine, that is, to remove the remaining berserk seal beast aura on the seal crystal!" When there was only the first-order fire attribute seal beast seal crystal that emitted a fiery red glimmer left on the bed, the old man suddenly turned his head and said to Meng Feng: "Doing this step is an extremely critical step in the entire refining of medicine. There are often many alchemists who start refining medicine by themselves without guidance, and they will stupidly and directly take the essence extracted from the seal crystals and medicinal materials to melt the pill. ”

"It is extremely dangerous to do so. Unless it is some seal crystals that have been eliminated by someone to remove the breath of the berserk seal beast, the other seal crystals have the violent aura left by the seal beast before its death. This breath can make people's minds confused, and if it is not properly controlled in the end, it is very likely to make people go crazy directly. ”

The old man was extremely solemn and said solemnly, and when Mengfeng saw the old man's appearance, he listened very seriously.

"In the process of refining medicine, we must first remove the remaining violent aura in the seal crystal, and then proceed to the last step, Melting Dan. And to remove the remaining violent aura in the seal crystal, it is not something that can be eliminated if you want to, this is to achieve a certain strength. Like the ordinary first-order seal beast seal crystal, the alchemist himself needs to reach the strength of the upper level of the Cheng Seal level to completely eliminate the violent aura left by the seal beast in it. ”

"The second-order Seal Beast Seal Crystal requires the strength of the high-level spirit seal level. The third-order Seal Beast Seal Crystal requires the strength of the Jun Seal level. That's it anyway, and so on. And when the realm is quite high, there will be a trace of the violent soul left behind by them in the seal crystal of some seal beasts, which needs to be eliminated with the help of some foreign objects and their own cooperation. Of course, if the strength reaches a very high level, it can also be directly eliminated by virtue of its own strong strength. ”

"At this level, you can't touch Feng'er for the time being, but when your strength reaches in the future, you will naturally know. Here, I don't have much to say about the teacher. Anyway, you just need to know that if you want to refine Huangpin high-level and above-level pills, you need the strength of the alchemist himself to reach the corresponding level. ”

After a series of words, the old man also swallowed his saliva, took a deep breath, and then continued: "Okay, then the teacher will remove the violent aura of this seal crystal." ”

As soon as he finished speaking, the old man waved his palm, lifted the seal crystal on the bed, and threw it into the clusters of pale golden flames.

Clusters of pale gold flames instantly enveloped the entire Seal Crystal, but instead of directly burning it, it revolved back and forth around it.

In the blink of an eye, five minutes passed, and at this moment, the fiery red seal crystal that emitted a faint light suddenly trembled, only to see a trace of slightly fiery red white gas erupt from the seal crystal, but as soon as the seal crystal came out, it was burned into a wisp of white smoke by the light gold flames surrounding it, and it drifted away with the wind.

"That trace of white qi just now is the violent aura remaining in the seal crystal. It is the safest, but more time-consuming, method that teachers have just used. It is to use its own flames to surround the seal crystal, so that the violent aura in it stays for a long time, and it is unbearable to bear the heat around it, and it is self-detached from the seal crystal. And our flame is just waiting for it outside, incinerating it directly. After the old man took the seal crystal out of the pale gold flame, he turned his head to Mengfeng and said.

"Uh, master. What do I think of this furious atmosphere, it doesn't seem to be a big deal, and it was burned by you as soon as I saw it. Meng Feng said with a hint of puzzlement on his face.

"This is because it is a sacred fire for the teacher, and because of the strength of the soul of the teacher. Otherwise, you think it is so easy to remove the violent aura from the seal? If you let those who do not have the holy flame to remove the violent breath from the seal, it will not be possible to complete it in a few quarters of an hour. The old man explained lightly.

"Okay, the master is now going to start the melting. After a moment of silence, the old man waved his hand and took out the essence from the small jade bottles on the table next to him, and threw them into the clusters of pale gold flames.

"Sneer......"

The essences extracted from various medicinal herbs collided with each other, and suddenly there was a piercing sound, and wisps of white smoke also floated up.

A moment later, when the white smoke dissipated, a slightly rough shadow of the elixir prototype also appeared from the pale golden flame at this time.

Looking at the shadow of the rudimentary form of this elixir, the old man bowed his head slightly expressionlessly, and then picked up the seal crystal that had been removed from the breath on the side and threw it into the light gold flame.

As soon as it entered the flames, this seal crystal turned into a fiery red liquid in an instant, and under the old man's intentional control, this fiery red liquid also suddenly collided with the prototype of the elixir and fused together.

Originally, it was a slightly rough pill with some crooked rudiments around it, but under the fusion of the Yin Crystal, it suddenly filled these crookednesses and turned into a complete pill, and finally under the calcination of the pale gold flame, it gradually turned into a mellow pill that exuded a faint fiery red halo.

The elixir was formed, but the old man's pale golden flame still did not take it back, but continued to let it calcine the elixir back and forth for a while before it was withdrawn.

As soon as the pale gold flame disappeared, the elixir that had been trapped in it suddenly appeared in the void. A strong medicinal fragrance, also because there was no flame obstruction, erupted violently, instantly enveloping the entire room.

Looking at the fiery red elixir floating in the void, Meng Feng couldn't help but lose his mind for a while.

An extremely precious Condensation Pill in his eyes turned out to be like this!
