Legend has it that there exist vast grinding stones as heavy as the earth in the underworld, capable of crushing any soul into fragments, regardless of how powerful they've become. The Reincarnation Grindstone Formation Jiang Li taught the siblings manifests this folktale.
However, what Jiang Li currently guided the brother and sister to set up was an understated variant.
The Reincarnation Grindstone Formation seemed like a world of its own—an area separate from the rest of the world's environment. Its gravity was ten times stronger, flattening the whales and making it difficult for them to even raise their fins.
Once again, ruthless ice spears appeared in the sky. With the extraordinary acceleration provided by gravity, they rushed towards their target with a frightening speed. The soldiers of the Yong Gu Area only managed to see a white flash before the whales, which were about to break free from the ice spears, were pinned back to the ground with new spears.
