Yuan Tiangang waved his sleeve, and nine green wooden stakes flew out, landing around the two Divine Demon Pillars, forming an oval-shaped ring.
The wooden stakes were engraved with formation patterns, seemingly forming a large array.
He quickly formed hand seals with both hands, and a blue halo rose from the jade pillar, connecting the two Divine Demon Pillars together, spinning rapidly with a deafening whistling sound.
The Heaven and Earth Aura inside the great hall was completely stirred, spinning along with the blue halo.
The two black and white vortexes behind the Divine Demon Pillars were also drawn in, slowly moving and gathering together.
Shen Luo understood Yuan Tiangang's intention and secretly activated the prohibitions inside the Divine Demon Pillars to assist Yuan Tiangang's spellcasting.
The speed at which the two black and white vortexes gathered increased significantly and soon fully merged together.
