The Book of Knowledge said, "Last time, we repaired the Heavenly Sphere Clock. In addition to being able to locate Dream Fragments more clearly, it also has the ability to explore seals. The cemetery established by the King of Giant Dragons must be related to dragons. As long as we focus on this point, we'll find it soon."
Rod nodded slightly.
"Alright, I'll take care of this matter. I'll have Liszt send someone to search for the Ancient Dragon Tomb."
The Book of Knowledge said, "Master, we might acquire more than one heart of the King of Giant Dragons. The Demon Dragon's Heart contains most of the dragon's power, and dragons have always had the custom of burying hearts. If we can find the Dragon Tomb, we might harvest many Dragon Hearts."
Rod curiously asked, "Won't they decay?"
"Protected by the Star Secret Technique, they won't decay no matter how many years pass."
