Wendy's soul was too weak now. In fact, her soul was like a transparent object, and she would just pass through Steve when she tried to touch him. As such, she was unable to even touch his face!
Steve deliberately ignited Wendy's desire to survive as he said, "I can teach you a practice that can help you gather your soul strength."
The Lemurian Civilization was proficient in spiritual powers and soul practices, so Steve had naturally mastered them all. However, the knowledge of how to reintegrate one's soul strength had not yet emerged among the Blue Star humans.
When she heard Steve's words, Wendy was shocked. She had never heard of soul training practices before.
But, after listening to Steve explain the training practices, Wendy's face became more solemn and dignified. As a level-five evolved being, Wendy's level of contact was much higher than Steve's, so hearing these things were particularly relevant to her.
