Du You thought for a moment, it seemed to be the case. "No wonder I've never heard of such a six-tier armor that can withstand a seventh-tier attack. In such a long time, things here should have appeared in the outside world. So that's why."
Du You also realized that perhaps the crafting of the God-slaying Weapon was not as he thought. Perhaps it was a huge waste of materials, or maybe these defensive materials were needed for something.
Plus, not many of these materials have appeared, so there are only God-slaying Weapons and no defensive equipment.
After all, they aim to improve themselves, and most importantly, hunt down seventh-tier native Divine Spirits. So strengthening attack is more useful than anything else. Better to kill the target in one go rather than blocking a couple of hits.
In Du You's view, if it weren't such a waste of materials, armor would have likely appeared long ago. It might have appeared, but he just didn't know, which isn't a strange thing.
