When she took that step and transformed into a starving ghost, she understood many things.
The small piece of beef jerky, why it could be given to her in the Despair Abyss, and why it could remain there.
Because at that moment, Yu Ziqing was already very certain that the piece of beef jerky in his hand must be able to break through the rules of the Despair Abyss and be given to her.
At that time, Yu Ziqing knew that this item, on a day in the future, would definitely be able to pull her out of the Despair Abyss. What he gave her then was a hope in reserve, although under normal circumstances, that day might never come.
This was something personally bestowed by the King of Ghouls, known as the proof of transformation. As long as she was willing, no one could stop her from completing her transformation, but she was not willing to use it right away.
Because this item was the Dao Mark that the King of Ghouls, without consciousness and self, returned with from the Void.
