In no time, the extremely fast Jiaojiao and Qin Xia came in too. After all, most of the zombies were blown to bits, and some of the crystal cores directly flew out. With Jiaojiao's ability to sense energy and their swift killing speed, it didn't take long to clean up a few hundred of them.
All done.
The backpacks on Jiaojiao and Qin Xia were full and heavy. Their harvest was obviously fruitful.
However, just as Jiaojiao finished speaking, Qin Xia furrowed her brows.
"What's that sound?"
She could hear it, and Qin Yu and Jiaojiao had heard it earlier too, but they chose to deal with their self-interest first - such as the crystal cores.
Because they were, deep down, selfish people who stick together. They might not harm others, but they wouldn't sacrifice their own interests for others either.
This is the apocalypse, not a charity. Sustainable strategies must be followed.
