After Yan Bingxuan finished demonstrating the spell, she casually took a cup of coffee and left.
Chen Mobai walked her to the door of the Cultivation Gymnasium, and thinking the two hours shouldn't be wasted, he returned to the "Spells Chamber". Following her instructional points, he started practicing the Cold Ice Technique.
Thanks to Yan Bingxuan's transferred Spiritual Power and personal experience, he had figured out how to transform his Five Elements Cultivation spiritual power into Ice Spirit Power. The only issue now was to capture that split second when the Ice Spirit Power takes form.
Even though he understood the trick, it would still require continuous and tireless practice to be able to spit out an Ice Breath at the exact moment when it has or hasn't formed.
Releasing it too quickly would result in frostbite to the twelve-story building, releasing it too slowly wouldn't produce the intended freezing effect.
