The Thunder-Chasing Wings were a Dharma Treasure recorded in the "Purple Firmament Thunder Art" practiced by Zhou Xun.
This treasure possessed immense power. With a single thought, the Thunder-Chasing Wings would manifest behind the user, and upon infusing them with thunder spiritual power, one could travel a thousand miles in an instant.
It was a top-tier auxiliary treasure. Moreover, aside from one's natal Dharma Treasure, this was one of the rare Dharma Treasures that could be stored inside the body and capable of growing alongside the cultivator.
