Song Hongfei and Song Ning's life and death still mattered to Song Kerou; after all, only with them could she survive in the apocalypse.
But, they've seen Song Wenwen and already know that she lied to them back then saying Song Wenwen didn't turn into a zombie.
If they found out that Song Wenwen was killed by her, she truly wouldn't have space to survive in this apocalypse.
She even thought that if those zombies just bit them to death, it would be perfect. That way, she could live with Song's mother, who was also a superpower user; at least someone would provide for them.
But the dangerous aura emanating from Song's mother came without restraint, clearly telling her that Song's mother would really beat her to death for the sake of those two.
