The ice sword is a great example of an alchemist putting in too much effort to make a weapon that is not as good as it could be. The alchemist claims that the ice sword has a major defect: it is made of ice, which wears out too quickly. He then shows the fire-blast sword, which is made with ash rock. The ash rocks have a high capacity for supporting the fire element, which means that the sword will be able to withstand an attack from the enemy's fire. The sword's defense will also be weakened because the opponent's defenses will be weakened by the addition of the ash rocks. The fire-sapping sword is made up of three fire elemental forms: fire combining, fire bursting, and fire tempering. The elder yan family member, the great elder, discovered this secret and combined the three forms, but no one was able to do so.
