9 Trials of Sky.
While the first was a mere matter of battling enemies, the trials became extremely difficult as time progressed.
And the content of the trials was even stranger. There didn't seem to be any rhyme or reason to the order or identity of the trials.
The 3rd trial was a matter of the arts. If one wasn't skilled in at least one of the four arts, it was impossible for them to pass this trial.
Among them, Xinyue was particularly skilled in music. She was professionally taught to play the zither and guqin from a young age, making it simple for her to pass.
Alexandra had a harder time due to her current state, but she wasn't at a major disadvantage in this trial. Due to Alice's continued insistence, she'd picked up painting as a hobby outside of battle long ago. After she was given the means to complete the trial, actually doing so was a breeze.
The 5th trial was a strange one in that it didn't seem to have any particular purpose.
