Capítulo 1698: You can insult the body, but not the personality

Ling Chuxi took a closer look and sure enough, there were a total of nine array techniques engraved on it.

Ling Chuxi was a little dumbfounded at that moment. A normal alchemy furnace would be engraved with arrays in order to allow the medicinal ingredients to fuse better and increase the success rate of refining pills. However, because the size of the alchemy furnace was limited, the difficulty of engraving arrays was too high. Therefore, there would usually be two or three arrays engraved at most. It was not like this super large alchemy furnace of his, which had nine arrays engraved on it.
