But Xu Ping now doesn't have Earth Fire, so he can only choose to use the array to ignite flames, though it consumes Spirit Stones.
After about half an hour, the Pill Furnace was sufficiently preheated, the purple-red body of the furnace faintly glowing with red light, and Xu Ping felt an astonishing high temperature.
He knew the preheating was complete, so he quickly formed a Magic Technique, and a wisp of Mana was injected into the small furnace. The furnace trembled, the lid flew up, revealing the round opening.
Xu Ping lightly moved his forefinger, the Storage Ring shimmered, and several jade boxes appeared in the air. They contained the Spirit Medicine needed to refine Qi Refining Pills.
He pointed at the jade boxes, each one opened, using Spiritual Power to levitate a Spirit Medicine above the furnace opening, slowly entering the furnace. With another gesture of Magic Technique, the furnace lid flew back, covering the opening.
