"This is a spiritual armour crafted using the Heaven Crow's Natural Silk. This only drawback is that this armour is a low grade spiritual equipment." With that, he shook his hand and a thin outer upper garment appeared within it.
The reason why he said it was a pity was because the Heaven Crow's Natural Silk was an exceptional smithing material, and it was extremely hard to obtain. Typically, even the worse of smiths would result in intermediate grade spiritual equipment, the better ones would always be high grade. To actually craft this low grade spiritual equipment, would mean that this was a failed product.
Mo Wuji immediately got tempted; this piece of garment could cover the entire region above the waist and below the neck. Clearly, this was no simple armour.
