This blue robe rapidly expanded in the wind, swelling to ten zhang in size in the blink of an eye, like a massive blue cloud, enveloping the two of them securely within.
Both Gu Yuntao and Xu Ping had a certain understanding of this Spirit Treasure's defensive power.
Though Gu Yuntao had yet to fully refine it and couldn't unleash its full might, they believed it should be able to withstand the opponent's attack.
However, what happened next left them utterly shocked.
"Crack!"
They witnessed the formidable purple Thunder Dragon, like an incredibly sharp blade, effortlessly tear through the powerful defense of the blue robe.
The purple thunder light flickered and lingered on the robe, and this seemingly sturdy treasure unexpectedly shattered on the spot.
"What!"
The two couldn't help but exclaim, their faces full of astonishment.
No matter what they had imagined, they couldn't believe that this blue robe's defense was so vulnerable, so easily broken by the opponent.
