151 Life Pill Sutra

"These Crystal Source Pills were refined over 300 years ago, but they are still of excellent quality and have abundant medicinal power. How rare."

Xu Ning praised, "This shows that the refining technique of this pill medicine is extremely exquisite. It can seal the medicinal properties of a pill for such a long period of time. Of course, how they were preserved for so long is also due to how the pills were stored. Speaking of this, this stone box is made of a special material that allows it to be extremely sealed. With such a tight seal, it can ensure that the medicinal properties of the pills can be preserved for a long time without leaking one bit."

After admiring the Crystal Source Pills, Xu Ning directly absorbed the six pills in the stone box.

'18,000 units of energy.'

To a certain extent, a Crystal Source Pill was an upgraded version of a Pure Source Pill.
