After a night of repeated collapses, Xia Na's condition finally stabilized in the morning.
As Ling Mo had guessed, Xia Na had indeed become a zombie, but she still retained a sliver of rationality. Compared to before, her "schizophrenia" had improved quite a bit, but only just that much! The current Xia Na was on the brink between a mutated zombie and a regular zombie, but her strength was greater than that of an ordinary zombie.
Ling Mo actually found a pattern in her "schizophrenia." As long as she wasn't in danger, Xia Na would maintain the state of a normal person, albeit a bit confused and rarely responsive to others, she still retained basic language skills and occasionally took the initiative to speak. However, once she felt threatened, that remaining sliver of rationality would be immediately replaced by instinct, transforming her into an extremely aggressive zombie.
