Bab 2521: Returning to the Third Heaven

The most special thing about this cauldron was its sturdiness.

However, a good pill refinement cauldron needed more than just sturdiness. It also needed a powerful ability to resist flames. This was especially the case when it came to refining Celestial King Tier pills. To refine such pills, one would need to use flames extracted from the Great Dao of Fire. Even Divine Metal would be slowly melted by such flames.

Divine Metal was sturdy, yet this didn't represent that it couldn't be damaged. It was just that it couldn't be comprehensively destroyed.

Ling Han's comprehension of the Great Dao of Fire wasn't deep, but he had still developed a sliver of understanding because he had refined a piece of Divine Metal before. He immediately summoned the Great Dao of Fire to burn the cauldron.

To his surprise, the cauldron didn't show any signs of softening even though it quickly became bright red. It was extremely resistant to flames.
