"But why?" Sui Xiong thought for a while, but he still did not understand how the newly mass-produced armor that looked very common in any way could resist the Great Disintegration Spell. Finally, he had to ask the Rune God like a school pupil asking his teacher for the truth.
The Rune God laughed and touched his long white beard like an old teacher and said, "The key to the problem is its uniform texture. Essentially, the Great Disintegration Spell has to find defects in the target structure and destroy them. But when the Great Disintegration Spell faces equipment with a uniform texture, it cannot exert its powers. This has long been known. For example, a shield can resist the Great Disintegration Spell by one polishing the shield with a piece of uniform crystal."
Sui Xiong blinked; he really hadn't known that.
