Bai Zemin and Lilith had met on day 1 of the apocalypse, probably no more than several seconds or a minute at most had passed since the moment the Soul Record abruptly broke into the lives of all living and non-living beings on Earth.
However, a doubt he had always had was precisely what Meng Qi had just asked.
Among so many humans... why on earth had Lilith set her eyes on Bai Zemin?
If she had met him after he got his hands on Blood Manipulation perhaps it wouldn't be so strange. After all, Lilith knew that Blood Manipulation was a powerful skill and it even turned out to be much more rare and special than she had previously believed.
However, Meng Qi had said it: Lilith had clearly been watching Bai Zemin even before he killed the level 5 mutant bee from which he obtained the skill scroll from which he learned Blood Manipulation.
