In fact, most cultivators don't actually practice Life Plate.
Because currently, most cultivators are not willing to train in the art of soul emanation, as the soul is deemed safer dwelling within one's own body. Therefore, most cultivators are without a Life Plate.
But Wei Shanshan is different; as a demon spirit capable of seizing the bodies of others, she necessarily cultivates a Life Plate.
Now, having fallen into Zhan Yun's hands, Wei Shanshan was given two choices by him, either hand over her Life Plate or die.
For Wei Shanshan, this was an extremely difficult choice, to forever give up her freedom to live or to face death directly, a decision not easily made.
Zhan Yun wasn't in a hurry either; he afforded Wei Shanshan the time to choose.
Because the Star Constellation Tower reminded Zhan Yun that acquiring the other party's Life Plate seemed to offer substantial benefits and even egged Zhan Yun on to take the other party's Life Plate.
