Bou didn't have much time to spare as the ground began to come apart below him. That meant an attack was coming... nothing else could have been the issue. He closed off the bottom of the hemisphere with a quick secretion of Kumoenkin fluid-thread, which hardened into the golden metal-like substance his family was infamous for.
Just in time, as well, the eruption shot the closed hemisphere into the air, driving it upwards. At the apex of the upheaval, Bou grabbed hold of the disc that made up the closer and spun the whole assembly mid-air, so he could properly aim. Narrowing his Byakuugan's sight, he locked in on the old man and flung the golden disc at him, hard.
