Ling Xiao summoned the Demon Blood Red Lotus Sword. The Demon Blood Sword swelled in the wind, transforming into a massive blade over a meter wide and more than ten meters long. It carried the two of them as they flew toward the Qin Family's island. Ling Xiao took the opportunity to explain to Song Mingyue, "It's like a temporary support pillar. A pillar can hold something up when there are no walls, but once the four walls are built, the pillar has served its purpose and can be removed."
Although Ling Xiao's analogy wasn't perfect, Song Mingyue still understood what he meant. "In that case," she asked, "won't the energy in the remaining Crystal Cores eventually run out?"
Ling Xiao chuckled. "Have you ever seen a Magical Beast use up all the power in its Crystal Core?"
Song Mingyue frowned. "How can you compare the two? Magical Beasts are living creatures! Crystal Cores are just inanimate objects!"
