"It's a coincidence, but it's also inevitable.
" The divine weapon forged by the Underworld Cult is called the 'Ring of the Divine Dragon'. It contains a large amount of the power of the Dragon Tribe in the Eastern Continent. There aren't many treasures or experts in this world that can restrain this power. The World Ending Twin Snakes, Brook, happens to be one of them.
" As we all know, Brook is entrenched in the trenches of the Endless Ocean. He not only holds a large number of souls of the Su but also the souls of many divine dragons. He knows the laws of power in the Eastern Continent like the back of his hand.
" In ancient times, Brook, who was still free at that time, made a dagger called 'Poisonous Teeth' in order to subdue the dragons entrenched in the Eastern Continent.
" It's said that the dagger can dispel the power of the Divine Dragon, especially the nemesis of the Divine Dragon's soul.
