Chapter 5143: The reason that was passed down from generation to generation

Ling Chuxi did not know whether the heavenly Fire of chaos was hidden in the alchemy furnace by the artifact refiner who had refined the great pure Dao heart furnace or if it was the work of Xu Ziqing's Grand ancestral master. However, she knew that the reason why the great pure Dao heart furnace had been passed down from generation to generation, with only one corner missing, was because of the heavenly Fire of chaos.

The alchemy furnace was not as strong as spirit swords, spirit knives, or defensive spirit weapons. However, in terms of frequency of use, it was far superior to other spirit weapons. Of course, it was also more likely to be damaged after being exposed to the high temperature of the spirit Fire for a long time.

In fact, many pill furnaces that had been passed down for a long time were carefully collected and rarely used. Otherwise, they wouldn't have been passed down.
