Tang Yan returned to his courtyard on Clear Sky Peak and lounged leisurely in a reclining chair.
His mind, however, was far from as peaceful as he appeared. He kept pondering every medicinal ingredient needed for the Mountain-Breaking Pill.
Refining Treasure Pills required large quantities of Profound Herbs, making the cost considerable.

The Mountain-Breaking Pill, used for cultivation, required thirty-nine medicinal ingredients in total.

This herb could neutralize toxins!
