The classic carrot and stick

Earlier, during his inspection of the terrain and after leaving Feng Tian Wu, Bai Zemin had shared with Lilith his new skill after Stone Heart finally evolved. Lilith at that moment was incredibly happy but also very shy since the evolution of Stone Heart meant that Bai Zemin was effectively in love with her and that the words he had said to her at that moment in the middle of the desert were not empty words; he knew that he was in love with her even if the Soul Record had not "approved" of it yet.

After seeing the effects of the new skill Immovable Heart, Lilith simply vowed to herself to never again be surprised by the crazy skills that Bai Zemin might obtain in the future.... As for whether she would achieve such a thing or not remained to be seen.
