The Lake Light Angel specifically recorded that she was hunted by the Ancient Elf Sanctuary!
Reading the "Lake Light Manual" after the "Time Manual" gives quite a humorous feeling.
Because the King of Time was an ancient elf!
However, in the era of the King of Time, the Ancient Elf Kingdom had already significantly declined, with almost all external cities lost. They could only hold onto the "Undying Sunset" Eternal City.
In the "Time Manual," he explicitly pointed out the reason for the decline of the Ancient Elves—the Divine Lords like Blood Moon and Dazzling Star used despicable means to kill the high-ranking ancient elves and continuously suppressed the Ancient Elf Kingdom!
The descriptions of the Seven-colored Tail by the Lake Light Angel and the King of Time are almost identical; both describe finding the seven colors to capture the Seven-colored Tail. Clearly, in their era, these seven colors could still be found.
