Vienna You and the Sacred Stone Chapter 22

Vienna You asked him to look at the box in his hand. There was a weak soul power inside, shaped like a feather.

Its color is as clear and blue as the deep sea, with golden threads wrapped around it, pulsing like life.

In their time, it was rare for the spirit puppets to fail to meet the standards, or for the spirit to escape due to battle. If they were not put away in time, there would be a danger of the spirit being scattered, so Vienna You always carried this box with him so that it could be released in time. Collect source spirits.

This spirit box is her most precious magic weapon. It not only prevents the source spirit from dissipating, but also helps to accumulate it.

This was how Elsie was picked up and raised by her.
