Tang Ao plans to wait until the alchemy is over, like Jin Wanchuan to find out whether there is nine color sky fire crystal in Xianxu or Langya world. If the nether fire can not be upgraded, Tang Ao will be bound by the flame when refining pills, which is not what Tang Ao wants to see. If there is no nine color sky fire crystal, Tang Ao is ready to temporarily refine a cluster of other flames to refine pills.

It's very difficult to find a flame that can be upgraded like the nether fire, but it's not difficult to find some high-grade immortal fire. A lot of fairy fire was born that grade, but due to unable to advance, so the value is limited. Although such fire is also a treasure, it is not so popular.

The most important thing is that there are so many such flames between heaven and earth that it is easy to obtain such flames. The Ziyang fire that ye Qiucheng gave Tang Ao before is just a bunch of such flames. However, Ziyang fire is only a little fairy fire. Now Tang Ao still thinks that the grade of Ziyang fire is too low.

After all, Ziyang fire can't be promoted after refining, and Tang Ao can't use it for long. In Tang Ao want to come, refining this can not be promoted Xianyan, at least also want to start three grade Xianyan. In Tang Ao's contemplation, there are more and more martial artists on the square outside the Wanbao tower. It is very rare for a top-ranking immortal alchemist to refine alchemy on site. After all, there are not many first-class elixirs in Xianxu. The top-ranking elixirs have not even appeared before.

Although many people do not understand alchemy, they still don't want to miss this opportunity. As for those who know how to make alchemy, they are very excited. Because watching the top alchemy masters like this can enhance one's understanding of Dan. After watching Tang Ao's Alchemy last time, a Dan master who had been stuck in the peak of the elixir division for a long time broke into the ranks of the first-class elixir masters in one fell swoop.

This matter is still only spread in a small range among Dan masters. Otherwise, if everyone knew about it, the square outside the Wanbao building would have been crowded. Even now, the square outside the Wanbao building is overcrowded. The news of Tang Ao's Alchemy even spread directly from Nanxu city to Beixu city.

Many martial artists in Beixu city are secretly envious. With the emergence of such a top-level Dan master in Nanxu City, the cultivation of the warriors in Nanxu city will certainly advance by leaps and bounds. Many people even complain about why they appear in the Beixu city when they come from the lower level, not in the Xianxu battlefield or directly in the Nanxu city.

The Danshi of Beixu City sighed secretly that he could not see Tang Ao refining pills. To know such a great event of alchemy is of great significance to Danshi. Unfortunately, the hostility between Nanxu city and Beixu City hindered the Dan Dao communication.

Wanbao tower courtyard square, Tang Ao naturally did not think so much. Tang Ao at the moment is carefully recalling the Dan Fang of Bingxi Dan, as well as some precautions for refining Bingxi Dan. This is Tang Ao's first time to refine Bingxi pill. Although Tang Ao asked for three parts of medicinal materials, Tang Ao still wanted to refine the pill successfully once.

After thinking about it for a long time, Tang Ao finally began to practice alchemy. This time, Tang Ao didn't put all the spirit grass into Shennong tripod according to the previous alchemy habit. Instead, he treated the fairy grass one by one like a normal Dan master, and then put them into the furnace for refining. At present, the strength of the second level of Aoxing's polar realm in Nanxu city can only be said to be at a low level.
