After resting for a while, Lin Ke turned his attention back to the Jade Slip in his hand.
The five-colored glazed body!
This was a Body Tempering cultivation art, and legend had it that it was a supreme art passed down by the founding patriarch of the Giant Strength Fire Prison Sect!
Yet it seemed that even the sect's founding patriarch had never practiced it.
Lin Ke suspected that the patriarch had obtained this Body Tempering art somewhere else.
The patriarch had known how powerful it was and coveted it, but ultimately could not practice it himself, so he had hoped his disciples and later successors would cultivate it.
In the end, not a single person had succeeded.
The crux of the problem lay in the Niwan Palace!
That was also why Lin Ke had been willing to spend money to acquire this art.
Although he had known how powerful it was to open his Niwan Palace during the Qi Refining Stage, he had never truly felt that gulf, as vast as a heavenly chasm.
Now he felt it.
The thirteenfold Dao Foundation was one example, and this Body Tempering art was another.
This was more than just a cultivation art. It represented a weighty legacy that countless outstanding figures throughout the Giant Strength Fire Prison Sect's history had been unable to attain.
It carried not only the oppressive weight of long ages, but also the chilling knowledge that those prodigies and geniuses had still failed after all their efforts.

There must be more to it than meets the eye... Lin Ke read the art with caution and reverence.
If he thought having a Niwan Palace guaranteed that he could master it,
