Lilith was not only trying to perform shooting three arrows, but also shifted its course. The inspiration came from the sudden rain, intending to wash the blood painted the greenery of the Mountain Peak.
She desired to cause a rain of arrows, with, of course, extreme precision.
As much as possible, she had to converse arrows as possible.
But she finally decided to shoot three arrows at once, even though it was a risk.
The decision also appeared they were about to have a final battle.
In addition, she was not only shooting the three Heaven Grade weapons, but was also utilizing her Art.
She was successful, to her surprise, in integrating the unity of Fire and Evil Aether to the arrows.
It was only recently she learned how to fuse the Fire and Evil Aether, and she accidentally saw it through her husband as well. Her husband had long succeeded by combining it, and was already inspired to create another Heaven Grade Art.
