Underground Gladiatorial Match

Had it been in the Immortal World, Tang Xiu wouldn't have believed it if this Water Progenitor Stone was sold as jewelry, but this was Earth. Tang Xiu had seen too many precious treasures in this world that were sold by ordinary people as regular objects.

She was surprised and glanced at the Heart of the Ocean again before slowly answering, "To the best of my knowledge, there's only one such aqua crystal of this quality. There have been several amethyst crystals in existence, the most famous of which is the 'Gem of Rose' owned by the Kingdom of Great Britain's royal family and is currently in the Queen's crown. Unfortunately, that treasure is not for sale no matter how much is offered."
