Jiu'er faintly guessed that Bernadino might know about some ability she possessed, one that could remotely notify Annan.
Even though he didn't guess the exact means or method... his previous attack on Jiu'er, where he extracted her soul, was clearly intended to make her call for help, rather than planning to fight her!
So that's how it is... Is the Book of the Celestial Chariot Annan's possession?
Then, perhaps the moment they asked about the "Book of the Celestial Chariot"...
... no, that's not right. Because Jiu'er really doesn't know what that thing is, it shouldn't be searchable in her memory either.
So it must have been before that.
Before they approached her, they already knew she was Annan's servant!
But in the Royal Capital of Noah, there were at least several people from Frostwater Harbor. Why target her specifically?
At this thought, Jiu'er suddenly had a jolt of realization.
An image abruptly emerged in her heart.
