"You're truly despicable!" Xue Qingcheng's voice carried anger, yet beneath that slight stagnation, it seemed she was also breaking the formation. That was indeed her style.
After I set down the detection needles, the formation disk in my hand immediately displayed the range of the grand formation's fluctuations.

"What? But he said the Boiling Immortal Formation can
