"It took thirty-six years to refine a Sky-reaching Spirit Treasure, but with full effort, the time could be reduced to about twenty years."
The Birthless Killing Sword is not complicated among Sky-reaching Spirit Treasures, yet its refining time also requires more than thirty years.
More complex Sky-reaching Spirit Treasures take over a hundred years to refine.
Jia Ren was led by Elder Qing to the deepest part of the Refining Palace, to a green jade bead.
"The Refining Techniques for Sky-reaching Spirit Treasures are all here. Heaven-reaching Refiners can study them at will without restriction."
"Furthermore, there is one more... the Refining Technique for Mysterious Heavenly Spiritual Treasures."
"It was left by the Founder of our sect; sadly, aside from those with a Heavenly Treasure Body, no one can refine it."
Elder Qing led Jia Ren into the deepest part of the Refining Palace, where a green jade bead was placed on a stone platform.
