This was not an ordinary fireball, but a plasma flame clump transformed from magic power. Before coming into contact with a solid object, it would maintain its clustered form. The temperature of its outer flame was not high and it was able to suppress the high temperature and high pressure inside.
However, the moment it made contact with an object, the fireball would explode instantaneously, releasing the high temperature and high pressure inside and causing an explosion and high heat that would ignite anything it touched.
Therefore, the best way to deal with this kind of fireball spell was to activate the magic defense shield for protection. The magic defense shield would reverse transform the fireball, returning it to its original form as omnipresent magic power, immediately causing the high temperature and high pressure stored within the fireball to disappear without a trace.
