So Tang Ao naturally saw the change of Chinese herbal medicine in Lu Yu's danstove. After seeing the speed of Tian Yun fire refining the essence of grass, Tang Ao secretly envied him. Although Dan fire could also make alchemy, it was obvious that refining some advanced Danshen drugs only if the ordinary flame of Dan fire was used. And in refining low-grade pills, although Dan fire is competent, but the speed is very slow.

used the best medicine to raise yuan Dan. One used thirty-six kinds of medicinal materials. After a while, Lu Yu put the herbs into the Dan stove in turn. But Lu Yu also distilled the essence of the seventeen herb. Seeing Lu Yu's means, Tang Ao knows that Lu Yu is absolutely not simple.

Lu Yu's action is not useless, but to the greatest extent lock the efficacy, so that the spirit of grass in the process of refining into pills, the loss of medicinal power to a minimum. Such a method seems simple, but in order to achieve this level on the alchemy way, besides the need for unusual flexibility, the changes in the essence of the essence of herbal medicine are also very familiar with each stage.

If he hadn't seen it with his own eyes, Tang Ao didn't believe that alchemists in Feixing continent could do this, because even Tang Ao himself could only achieve this level by refining some familiar pills. Of course, Tang Ao didn't know whether Lu Yu often refined the best Yangyuan pill.

in Lu Yu distilled seventeen kinds of spirit grass essence, Tang Ao also a kind of spirit grass essence has not been thoroughly extracted. Because Tang Ao put all the spirit grass into the alchemy furnace, it's not like it. After Tang Ao put all the spirit grass into the alchemy furnace, Tang Ao also refined all the spirit grass together.

If this scene is known by other Dan masters, they must be scared to say nothing. The reason why the alchemist has to refine the spirit grass in turn is that the alchemist's mind is limited, and he can't control the changes of too big spirit grass in the furnace at the same time. But Tang Ao's mind is too strong, obviously not suitable for the conventional alchemy methods. In order to reduce Tang's power in the process of making medicine.

Time goes by quietly. Although Tang Ao's speed of refining pills has been accelerated after his recovery, Tang Ao's speed is still too slow compared with Lu Yu, who has sky cloud fire. After Lu Yu refined all the 36 kinds of spirit grass, Tang Ao's spirit grass was still not refined. However, Tang Ao also found an interesting thing, that is, Lu Yu did not use the classic formula of refining the best Yangyuan pill, but used his own modification.

Although Lu Yu's modified spirit grass is different from his own, Lu Yu's thinking is exactly the same as his own. Seeing this, Tang Ao is also secretly praising. You should know that Tang Ao is the descendant of Shennong emperor, and has such wonderful books as the collection of Baicao. Therefore, he has a very good understanding of many spiritual grasses. Tang Dan can make such a modification.

Lu Yu can't foresee how talented Lu Yu is to become a demon. Originally, Lu Yu wanted to see if Tang Ao had modified the Dan formula, but it was a pity that Lu Yu didn't expect that Tang Ao put the spirit grass into the alchemy furnace once and for all, so Lu Yu didn't have time to see it.
