Liu Ming's expression changed slightly upon hearing Motian's words, revealing some difficulty.
The purple arcs of lightning appearing on the surface of the Demon-Sealing Plan clearly indicated some kind of formidable power, one that could easily withstand the power of the Chaos Stone Monument; it was not something easily broken.
After a brief contemplation, he seemed to have thought of something, and his gaze brightened. With a flick of his palm, he produced a half-broken ring, which was a fragment of the Heaven-Earth Thunder-Controlling Ring.
He waved his hand and cast a spell, integrating it into the broken ring.
The broken ring glowed faintly, flying towards the purple barrier.
Thud!
The ring, although blunt and without an edge, easily pierced into the purple lightning barrier.
