Chapter 1408: Old man in the city

Although the elixir is good, all medicines are three-point poison, and if there is nothing wrong with taking the elixir, it will definitely cause problems. So this idea is absolutely unworkable. Tonic pill is still barely possible, like healing pill, who will take it if he is not injured? However, after successfully selling the pill to Yue Yun just now, Tang Ao felt that the pill on the stall was not completely unsellable here.
"You show me your meditation pill." When Tang Ao was thinking about how to prove that his pill is genuine, an old man behind Tang Ao suddenly said. This old man sells spirit grass, and Tang Ao saw a lot of medicinal powder, spirit wine and all kinds of low-to-medium spirit grass in his stall. Tang Ao noticed this old man when he came here, but he had been dozing off before. Tang Ao didn't expect that although he seemed to be dozing off, he knew exactly what was happening around him.
After the old man asked to see the pill that Tang Ao refined, Tang Ao didn't refuse either, grabbed a bottle of Jingxin Pill and threw it to him. But after Tang Ao threw the medicine to the old man, the old man was still leaning against a stone with a hat covering his head, without moving. In this way, the jade bottle that Tang Ao threw in the past would naturally be broken.
However, Tang Ao's face did not change in any way, and he didn't even have the idea of ​​catching the jade bottle. The jade bottle containing the Meditation Pill fell freely in the air like this, just about to fall to the ground. But at this moment, a subtle wave of vitality came out, and then the jade bottle that Tang Ao threw out steadily fell in front of the old man.
The old man did not look at Tang Ao, but straightened the hat on his head. At this time, Tang Ao also saw the old man's face. This old man seemed to be very old, and his appearance looked older than Qi Shu Gong. The eyes are very muddy. With such a pair of eyes, I am afraid it is not so easy to see things clearly.
But after picking up the pill that Tang Ao had thrown, the old man carefully observed it. After seeing the full and round color of these meditation pills in the jade bottle, the old man immediately became interested. After that, he plunged his soul into the pill, and his expression immediately became exceptionally exciting. On the stalls in Fulongfang City, because most of the pills are made by some second-rate or even third-rate alchemists, the effect is very poor, so they are called waste pills.
However, Tang Ao's bottle of pill, a total of six pills were refined in the same furnace, indicating that this bottle of pill was full of pill during refining. Usually the pill that is full of pill is not bad, so the old man began to investigate this bottle of pill carefully. It's okay if you don't look at it. From this look, the old man is a little doubtful whether he is dim-eyed.
Of course, this was not because the pill that Tang Ao refined was not good, on the contrary, it was because the pill that Tang Ao refined was too good. When refining a pill, one of the more important steps is to refine the medicinal solution. As long as the essence of a medicinal solution can be extracted, the pill can be refined, but the pill refined at this time is called the lower-grade pill.
When the medicinal solution is refined to more than 30% and less than 70%, the refined pill will be a middle-rated pill. The pill that the purity of the liquid medicine is 70% to 90% is called the top grade pill. If the purity of the medicinal solution is above 90%, then the refined pill is the most precious premium pill.
At this moment, the bottle of pill that Tang Ao threw, the essence of the liquid medicine actually reached 90%. Xia Baicao has practiced the pill for a lifetime, but his most powerful attempt to extract the essence of the medicinal solution was only to purify the essence of the medicinal solution to 80% purity. Therefore, Xia Baicao would be unbelievable after judging that the bottle of Jingxin Pill refined by Tang Ao was 90% pure.
