After Xu Mumu woke up, she took Yin Yang to lie down in the room and then walked out to separate the people showing signs of zombification at the Yin Family, to prevent them from turning into zombies and biting others.
Once Xu Mumu had settled everything at the Yin Family's main house, she didn't bother with the others. Yin Yang's other uncles' families, on his part, felt there was no need to intervene, letting them experience it as they usually act recklessly. This may make them listen better in the future.
After everything was tidied up, Xu Mumu returned to the room and took out the weapons she had prepared long ago. She placed two Tang Blades in Yin Yang's room, planning to later pretend they were collected by him.
These Tang Blades were bought specially by her and Yin Yang to deal with the initial zombies, which was completely sufficient. Regarding later stages, she wasn't very clear on it; she only knew that the zombies evolved faster than humans.
