The Heavenvoid Cauldron had a flat bottom, two handles, and three legs. At over a meter tall and three meters wide, it couldn't be considered very large.
It had a slightly protruding lid covered in carvings of beasts and insects along with various landscapes. Although they appeared rough and crude, they were true to life and exuded an aura of untamed antiquity.
Just as the cauldron emerged from the hole, a faint hum was heard that gradually became louder. At the same time, the blue flames surrounding the cauldon flared before swelling to several times their original size.
Having originally been standing near the hole, Han Li and the Bone Sage revealed expressions of shock at nearly the same time and increased their distance from the altar.
The entire area within thirty meters of the altar glowed with faint blue light and was completely frozen over.
