Lei Xinggang, the youth with purple brows, and the enchanting woman suddenly transformed into three blinding rays of lightning, swiftly spinning in the void within a hundred-zhang radius around Zhao Sheng, resembling three long and thick lightning arcs, accompanied by bursts of thunderous roars.
In an instant, the Thunder Cloud Domain above their heads rapidly expanded, intertwining with each other, and in the blink of an eye, merged into one vast cloud over a hundred li wide, with electric light like the sea within thick black clouds.
As soon as this cloud formed, countless black clouds appeared in the sky out of thin air, turning the entire heavenly vault into a dense mass of dark clouds, with thunder rumbling loudly.
Seeing the Thunder Domain achieve Great Success, Lei Xinggang suddenly halted his figure, raising his right hand with a wild laugh. In a flash of thunder light, a square-shaped seal appeared in his hand, entirely dark purple but engraved with nine dragon patterns.
