Although pills are good, but every medicine has three parts of toxicity. When there is nothing wrong with taking pills randomly, there will be definitely problems. So this idea is absolutely unworkable, tonic class pills are still reluctant, like healing pills, who will eat without injury? However, just after the successful sale of pills to Yue Yun, Tang Ao felt that the pills on the stall were not completely sold here.

"Show me your meditation pills." When Tang Ao was thinking about how to prove that his pills were genuine, an old man in the rear of Tang Ao inclined suddenly said. This old man is selling spirit grass. In his stall, Tang Ao saw many medicine powder, spirit wine and all kinds of low and medium-sized spirit grass. Tang Ao came here to notice the old man, but before he had been dozing off. Tang Ao didn't expect that although he seemed to be dozing off, he was clear about what happened around him.

After the old man proposed to see the pills refined by Tang Ao, Tang Ao did not refuse. He grabbed a bottle of meditation pill and threw it to him. After Tang Ao threw the pill to the old man, the old man was still a bamboo hat covering his head and leaning against a stone without moving. In this way, Tang Ao threw the jade bottle in the past naturally to be broken.

But Tang Ao's face also did not have any change, did not even hand to catch the jade bottle's idea. If you have a jade bottle in your eyes, you will see the free falling in the air. But just at this time, a subtle wave of vitality spread out, and then Tang Ao threw out the jade bottle firmly fell in front of the old man.

The old man didn't look at Tang Ao, but straightened the bamboo hat on his head. At this time, Tang Ao also saw the face of the old man. The old man seemed to be very old, and his appearance looked older than the seventh uncle. Eyes are very turbid, such a pair of eyes, I am afraid that it is not so easy to see things clearly.

But the old man picked up the pills thrown by Tang Ao and observed them carefully. After seeing the plump and mellow color of these meditation pills in the jade bottle, the old man immediately came to be interested. Then he put his soul into the pill, and his expression immediately became more wonderful. On the stalls in fulongfang City, most of the pills were made by second-class or even third-class alchemists, and the effect was very poor, so it was called abandoned pills.

But Tang Ao's bottle of pills, a total of six are refined in the same furnace, indicating that this bottle of pills in refining is full of pills. Usually, the pills filled with pills are not bad, so the old man began to explore this bottle of pills carefully. It's ok if you don't look at it. The old people have some doubts about whether they are old-fashioned or not.

Of course, it's not that Tang Ao's pills are not good. On the contrary, it's because Tang Ao's pills are so good. When refining pills, one of the more important step is to refine the liquid medicine. As long as we can extract the essence of 10% liquid, we can make alchemy, but at this time the refined Dan medicine is called the inferior product.

When the liquid medicine is refined to more than 30% and less than 70%, the refined pill is a medium evaluation pill. The pills with a purity of 70% to 90% are called top-grade pills. If the purity of liquid medicine is more than 90%, then the refined pills are the most precious.

at this moment Tang Yao threw this bottle of Dan medicine, the essence of the liquid reached 90%. Xia Bai Cao has practiced Dan for a lifetime, but he only refined the essence of the liquid to the purity of 80%. Therefore, after judging the Tang Jing's bottle of Jingxin Dan, the essence of the liquor reaches 90% purity, Xia Bai Cao can incredible.
