Stone of Immortality's appearance was not only sensed by Cyr, but also by Serena and a few people with some uniqueness about them.
However, among them, only Cyr and Serena were able to enter the Bizarre Beasts Cave.
Serena came to the Immortal Heaven World immediately after sensing the Stone of Immortality.
Yes, she was a reborn queen from the Clear Sky World, but her identity is not limited to just being a queen of a minor world. She had two more identities. Just like Cyr, she wasn't a native to this galaxy.
In search of the legendary Supreme Stones, she ventured into this abandoned galaxy nearly a hundred years ago. However, the entire galaxy had been sealed off by a formidable forcefield. This barrier not only concealed the galaxy from even the most advanced detection systems but also prevented anyone from entering.
