"Hoo ~" time did not know how long, Tang Ao light spit a breath. So far, Tang Ao has finally distilled the essence of the fruit essence to 96% purity. According to Shennong's Alchemy record, this purity is the limit of the essence of Baihua fruit liquid. However, Tang Ao did not stop there because he was worried that time was too late, so Tang Ao was anxious to fuse the essence of the liquid medicine.

Now Tang Ao observation found that time is not so tight. Because the remaining four were not able to refine the pills so quickly. Because Tang Ao is the first time to refine the best Yangyuan pill, it is not very clear about the time it takes to produce the best Yangyuan pill. After refining to this meeting, Tang Ao already understood that without four or five hours, these people would not be able to refine pills.

Once read this, Tang Ao naturally did not worry. And Tang Ao as a result of the Shennong Di Dan inheritance, the slowest process of refining the Dan medicine is the process of refining the essence of the medicine. After the fusion of the liquid medicine, the aggregation of Dan medicine is very easy for Tang Ao.

"It seems that this pill is not so easy to refine. In this case, I'll try to see if I can purify the Yangyuan pill to 99% After soul reads to scan several people around one eye, Tang Ao thinks secretly in the heart. Tang Ao was not in a hurry to fuse the liquid medicine Ning Dan, but continued to refine the flowers and fruits.

Baihuaguo is a kind of very special spirit grass. Among many pills known by Tang Ao, most of them can be added into it to harmonize their properties. The fruit is naturally absorbed by the essence of all kinds of grass, so it can play a complementary role with all kinds of grass. But it is also because of this, resulting in a lot of impurities in the fruit.

hundred flowers grow in the process of absorbing all kinds of Ling grass around the rhyme and refining their essence. If all the rhyme that has been absorbed is refined, then the hundred flowers and fruits are naturally the essence. However, the reality is not as beautiful as imagined, and the aura absorbed by flowers and fruits can not be fully refined. After a considerable period of time,

was transformed into the essence of the fruit of the 100 flowers and fruits, and those auras without refining were deposited in the flowers and fruits, and the accumulation of impurities became natural. Because these impurities are accompanied by the growth of flowers, so it is not so easy to remove these impurities. After repeated research, Shennong found that the purity of the fruit could only be purified to 96%, which was difficult to improve.

In the alchemy furnace, the red Dan fire was blazing. Tang Ao in the palm of the vitality of a spit, Dan fire is immediately stimulated, generally in the furnace beating. With the injection of Tang Ao yuan Qi, the temperature of Dan fire rises suddenly. Generally speaking, the temperature of Dan fire for refining liquid medicine should not be too high. But there are exceptions to everything. Just like refining the essence of passion fruit, if you want to improve the purity of passion fruit, you can't use ordinary fire.

Of course, there are risks in doing so. The hot high temperature can easily turn the spirit grass into ashes. After Tang Ao removed the original three kinds of auxiliary spirit grass, he had to have hundred flowers and fruits to refine the best Yangyuan pill. If the hundred flowers are burned to ashes in the process of refining, then this furnace of pills will be completely abandoned.

No matter how superb Tang Ao's Alchemy skills, in the absence of flowers to neutralize the medicine, even if the furnace is not fried, there is no way to coagulate the pill. So at the moment, Tang Ao really played up the spirit when refining hundred flowers and fruits, because as long as Tang Ao is a little bit careless, it will lead to the failure of this furnace of pills. Now Tang Ao's Alchemy ability has just been recognized by the Dan League. Naturally, Tang Ao doesn't want his alchemy ability to be questioned because of this small mistake.
