Hearing Wu Xia say that, Catherine quickly withdrew her foot.
Right where her foot had almost reached, a thin mist suddenly appeared faintly.
And that thin mist instantly turned into ice.
It was imaginable that if Catherine had stepped on it just then, she would have been frozen instantly.
"That was close!"
Catherine, with a relieved expression, patted her chest.
At this moment, Wu Xia took a step forward, bent down slowly, and looked at the frozen lake.
There was a strong fluctuation of Spiritual Power beneath this frozen lake.
And this type of freezing was unusual.
Wu Xia's left hand gathered Spiritual Power and he swung out a palm.
A heavy palm flew over the lake, but the ice-sealed lake remained undisturbed.
This palm seemed to have no effect.
"How could this be?"
Catherine, with a face full of surprise, took out a high-tech device to scan, but it could not pick up any useful information.
Seeing this, Wu Xia gave a cold smile.
