The black giant tripod towers here, the ice blue is like the soul blood of the melting glacier, with a rich fragrance, oozing out from the black tripod wall, dyeing through the small semi-black tripod.

Faintly, you can hear a burst of heart-rending roars.

The time for refining the soul medicine has been a full three days.

Wu Di stayed where he was, his eyes staring at Hei Ding, and he never moved away once.

And the four demons under him, since the last time Wu Di rewarded them with the purple flame python breath, they have devoured it, and their intelligence has improved a lot, which is about the same as an adult.

The stick demon, the gun demon, the sword demon and the sword demon, like the four elephants guarding the four directions, are guarding the surroundings of the black ding.

The ghost soldiers under their hands were dispatched by them within a radius of ten miles from Heiding, but if there was any abnormal phenomenon, they would give back to them, which showed that their intelligence level had indeed improved a lot.

Compared with the four demons who would only accept Wu Di's orders and fight and kill before, such four demons have more 'demon' demeanor.

Finally, three days later, there was finally a trace of abnormality on the black ding.

Originally, it looked like a huge crack with a flaw in the Black Ding, that is, in the line of heaven that was originally used by the Black Mountain people to enter and exit, a white light flickered.

After this white light flickered, the giant tripod seemed to have received some kind of stimulation, and it actually began to shrink visibly with the naked eye!

Bang la la ~ boom.

As the black tripod shrank, the rocks and soil clods attached to the tripod wall began to fall frantically under the squeezing of each other.

In the roar, a black tripod that was more than half smaller than the previous black tripod appeared in front of Wu Di's eyes.

The black rock on its body has fallen off, revealing the original black Ding Wall, although it has been eroded by the mountain stone flowing water for many years, but the Ding Wall is still shiny, and Wu Di also saw the various lines and carvings of birds of prey that were originally covered by the mountain stone on the Ding Wall.

What's even more surprising is that the lines that originally looked like cracks, after the mountain stone fell off, turned into a cone-shaped hole on the tripod's body, and the situation in the tripod can be seen from this cone-shaped hole.

What kind of crack is there, it's clearly a well-disguised observation hole!

This is the true face of Heiding!

Wu Di's eyes narrowed slightly, through this observation hole, he could see that in this tripod, the original Black Mountain City had disappeared, and even the soil had disappeared with it, leaving only the black pitch of the tripod, and at this time, the tripod cavity was like a chaotic mixture of light, as if a lot of very messy light was softened in the black tripod, and he could vaguely see that these lights were clearly the souls of the previous Montenegrin people!

If I'm not mistaken, this should be the second step in refining medicine.

There are three steps in refining medicine, removing impurities, refining, and condensing pills.

No matter how the techniques of each alchemy master change, they are just derivatives of these three steps, as the saying goes, everything changes are inseparable, Wu Di can see that under this technique, it has already reached the second step.

The first step of decontamination has been carried out thoroughly in the previous three days.

"Refining is the most critical step in alchemy, if it can't be refined thoroughly, the efficacy of this pill will be very poor, if the degree of refining is poor to a certain extent, it will even make the originally beneficial pill become a poison pill. ”

In the sacrificial spirit code he had seen before, the sacrificial spirit also knew how to alchemy, but it was not practiced in this way, but by the most primitive means, that is, by using fire, like this to use the ding to refine the pill, in a sense, this can no longer be regarded as alchemy, but more like the operation of a machine.

However, for the beginner Wu Di, seeing the alchemy process for the first time is finally good for him.

"There are many techniques recorded in the Ritual Ritual Codex, including alchemy, talismans, puppets, formations, refining tools, etc., almost all of them. ”

No wonder the previous Ah Gong of the Aconitum clan did not hesitate to use the power of the whole clan to snatch this sacrificial spirit code, if it was Wu Di, he would not hesitate to make a move.

It's clearly an encyclopedia.

"The soul medicine has a great effect on me now, and the soul medicine can also ensure the promotion of the four demons, and when the time comes, the combat power can be greatly improved!"

"A person who can use such a large amount of alchemy, his technique will naturally not be bad, as for this black tripod...... It should also be a rare treasure. ”

The more you look at the black tripod in front of you, the more it looks like a fragrant bun.

And just like that, another three days passed.

The process of refining was completed under Wu Di's nose.

At this time, looking through the observation of the hollow Wang Ding, there was no longer a chaotic scene to see before, as if it had been washed, in the past three days, there was constantly black smoke emitted from it, this smoke was extremely unpleasant, and when it touched the object, it directly corroded the object into a pool of thick water, which seemed to be extremely corrosive.

In the course of three days, such smoke continued to emit out, and the light cluster in the tripod became clearer and clearer, and it became smaller and smaller, and the tripod seemed to change with the change of the light cluster, but it was also shrinking.

In the end, a mouthful of the big ding, which was only one-tenth the size of the previous ding, appeared in front of Wu Di.

Such a big ding, it has shrunk into a big laugh as big as a small hill, and if you don't see it with your own eyes, it's hard for ordinary people to believe it.

Three days after three days, a three-day cycle, in six days, the soul medicine sacrifice has been completed two-thirds of the way.

Now, it is finally the last and most important step to start this refining medicine.

Ning Dan!

No matter how brilliant the previous technique is, once something goes wrong with Ning Dan in the last step, it will directly be wasted.

It can be seen that Ning Dan is important.

Generally speaking, the alchemist must be present in person, otherwise the probability of becoming a pill is too low.

Obviously, there is no so-called alchemist in this soul elixir, and even the alchemist does not know that this elixir has already begun to be refined.

In this way, this last step is completely a matter of looking at the face.

Wu Di looked at it, with no joy or sadness on his face.

Although the soul medicine is important, it does not make him lose his mind, not to mention that there is an anti-heaven existence like the Ziyan Python in his hands, so such an elixir is dispensable for him, he just looks at it with a mind to learn alchemy.

If the pill can be made, it is naturally the best, if not, forget it.

However, the more critical it is, the more likely it is to get out of trouble.

The Dan Furnace, which had always been calm, suddenly began to tremble after completing the second step of refining.

A black light flashed from it.

That light is very fast, and it is also very fast, if it weren't for the unique aura on his body, even Wu Di wouldn't be able to notice him!
