Usually in the process of alchemy, purification and harvesting are actually the most difficult steps. Please search for the most complete! Don't look at Mu Fan, who has the fastest update, can easily complete the purification, that's because he has a heavenly guide to the Tao.

And Mu Fan knew very well that this was still when he didn't use Heavenly Fire, once he used Wu Xinghuo Alchemy, he would waste less spirit grass in purification.

However, he also knew that if he really used Wu Xinghuo, then his death time would come.

Therefore, it can be said that if it is just purification, there is no pressure on Mu Fan at all.

"Purification is the most important step in alchemy, and the effect of purification almost determines the quality of the elixir. However, this second round of competition is not the purification of the spirit grass, but the purification of the elixir. Speaking of this, Elder Mu paused.

"Ah...... What? Isn't it a purification of the spirit grass?"

"What kind of purification method is that?"

......

Elder Mu's words made many people puzzled, if you want to talk about purification, it is of course the purification of the spirit grass in alchemy!

Mu Fan was also confused by Mu Lao's words, he thought that purification was quite pure for the spirit grass! But as soon as he thought of this, he slapped his forehead with his hand, and said in his heart that he was really stupid.

If it is the purification of the spirit grass, this is simply a snake to add to the picture, the third round of the competition must be alchemy, in fact, the steps of purification have been assessed at the time of alchemy, why bother to disassemble it and assess it separately!

It seems that this second round is not so simple!

"The purification of Dabi this time is the purification of the pill, strictly speaking, the purification of the waste pill. Saying that, Mu Lao waved his right hand, and a jade box appeared in front of everyone.

"Now each of you has a foundation building waste pill in front of you, and in the end, the less impurities there are in the foundation building pill, the higher the score will be. Mu Lao said lightly.

Everyone's hearts suddenly cooled a lot, purifying the waste pill, this is not an ordinary difficulty!

Moreover, the higher the grade of the waste pill, the more difficult it is to purify, and ordinary first-grade pills may not be able to do it at all. So as soon as Mu Lao's words came out, some people had already given up.

Mu Fan also frowned, he had never purified the waste pill, firstly, after the waste pill was purified, even if the impurities in it could be removed, it was still a waste pill, and secondly, it was very energy-consuming.

Purification is an extremely mind-consuming thing, who will be idle and have nothing to do to purify the waste pill.

"Okay, your purification time is half an hour, let's start now!" Regardless of what the people below thought, Mu Lao retreated after speaking.

Whether you like it or not, it's a game.

Therefore, when many people get the foundation building waste pill, they begin to ponder it. Of course, not everyone is sad, at least not Xiao Li and the others who finished in the first round.

There are several people in this who are second-level Danshi, and they may not have done it before, but they still have some experience in refining Zhuji Dan, at least they still have some clues.

Mu Fan stared at the foundation building waste pill, his face was very calm.

Refining the Waste Pill and purifying the Spirit Grass are not much different to him, and the Heavenly Guiding Dao Technique can completely draw out the impurities in it. Immediately, he looked at the others and saw that some had already begun.

Taking a deep breath, he was going to fight for it.

Originally, he came to Heze City mainly for the matter of cold words, if he could enter the Heze Medicine Garden by participating in Danby, he might be able to find the double-leaf clover, but the words of Mu Lao and Ouyang Qianhe before made him have some ideas.

The realm he is in now is just a low-level realm, and his aura is thin, if he can go to a higher-level realm, then his cultivation resources will definitely be much richer than now.

If he is still the same as before, he can't cultivate, and that's it. But now that he has a treasure like the Heavenly Seal, if he can't cultivate to a higher level, he will end up just a handful of loess in the end.

Therefore, he must work hard to cultivate, and maybe he will be able to unlock the secret of the Celestian one day.

Thinking of this, he became more clear about the direction of his cultivation in the future, and this Danbi was a good opportunity.

The Heavenly Guiding Dao Recipe quickly operated, and Mu Fan took out the Dan Furnace and directly sacrificed the inner fire of the foundation.

"Whirring ......"

The fire in the foundation was sacrificed, and Mu Fan began to purify.

There are too many impurities in the waste pill, and if you want to purify it, you must strip out all the impurities in the waste pill, plus Mu Fan also has experience in refining the Zhuji Dan, so this is not a difficult thing for him.

Under the operation of the Heavenly Channel, Mu Fan controlled the internal fire to continuously peel off the impurities in the waste pill, as if it was a candy that fell to the ground, covered with dust, he just had to keep bringing out the dust.

So Mu Fan didn't think about it that much at all.

The same is true for everyone else, who is methodically purifying, but there are also others who are simply overwhelmed and at a loss for what to do and where to start.

There are prohibitions and isolation in everyone's position, so it is impossible for people from the outside to see what is going on inside.

At the beginning, Mu Fan's purification work went very smoothly, and his Heavenly Channeling Dao seemed to be born to directly separate or connect different rules, breaths, and other substances.

But soon Mu Fan frowned.

Although he stripped out the impurities, the effective parts that were not impurities did not go as he thought.

In Mu Fan's opinion, in addition to the impurities, the remaining part of the waste pill is the active ingredient, but when he peeled off the impurities, he found that the rest of the part was also disintegrating.

This collapse is not only the drop of the pill ingredients, but also the medicinal power. Mu Fan's heart sank, if he continued like this, then the last entire waste pill would be purified into emptiness by him, that is to say, the result of purification would be that the entire pill would be gone.

Mu Fan hurriedly stopped, what he had to do now was to continue to shape the pill when the impurities were purified, otherwise according to the previous way, this question would seem to be simple.

"That's right, Reiki!" Mu Fan suddenly thought of a problem, when he first started refining the pill, the pill could not be condensed and formed, because he listened to the words of the ghost pill and did not attract spirits.

That's why he had no way to refine the elixir.

Now it seems that this is also the case! If you continue to attract spirits while purifying, won't you be able to preserve the shape of the elixir? At least you won't let it collapse completely.

Thinking of this, Mu Fan was even more energetic, and carefully introduced the surrounding aura into the Dan furnace.
