To catalyze the process at freezing point temperatures.
Zhiyan's expression flickered, but then she saw old Fei smiling at her from mid-air, she pouted and refocused her mind.
By using freezing point temperatures to catalyze, when the temperature of the Poison Bone Flute dropped low enough, she could then use flame to calcine it, thus solving the problem of its low ignition point.
Having realized this, Zhiyan breathed a sigh of relief, her mind activated, and Yin Energy continuously flowed from her body, coating the Poison Bone Flute. The flute, shaped like a hand bone, became covered with a layer of frost crystals before freezing solid.
Not until the ice around the Poison Bone Flute was about one foot thick did Zhiyan wrap it in Soul Power and then catalyze it with Yang Energy. The scorching flames burned a clear and surging aqua, making the Poison Bone Flute within the ice all the more dazzling.
