The disappearance of Green Sorrow didn't cause much of a stir at Hogwarts Witchcraft Academy. After all, there were only so few people, asking casually would reveal what happened.
Gu Shanhai was immersed in his experiments. Apart from his research on the Time History Book pages and the World Tree leaves, Gu Shanhai was also deeply studying the Elf Clan, a special race wearing the guise of elves.
"Something's not quite right." Gu Shanhai sighed, his expression turned peculiar.
The process of dissection and research went smoothly, everything seemed quite normal, yet he could see the underlying issues in their bloodline.
"Fingernails, why are there fingernails?!"
Gu Shanhai was momentarily perplexed.
The elves' world-traveling ability, upon in-depth research, he found its root cause.
It was the fingernails, a special structure formed by human fingernails and toenails.
This slightly challenged Gu Shanhai's worldview.
