Cowardly but obedient lambs
What did make Bai Zemin feel just, very slightly uncomfortable, was that even if he did not know these people before this and even had no idea that they were among the survivors, when he killed them he did not have the right to choose whether he wished to know them or not.
The reason? It was because every time Bai Zemin broke a survivor's neck, the following messages appeared in green letters flashing in his retina:
[You have acquired the Soul Power of Chen Luochen level 0].
[You have acquired the Soul Power of Mei Xiao level 0].
[You have acquired the Soul Power of...].
[You have acquired...].
Again and again, a small part of each person's Soul Power was absorbed by him and Bai Zemin was able to learn their names and some simple things like how old each one was. As for getting some kind of power from them... Considering they were just normal survivors, Bai Zemin naturally didn't expect something like that.
