Ye Xuan was responsible for the eastern and northern areas, while Chu Miao searched the western and southern districts.
Neither needed to walk through every street.
Crystal cores flew out from beneath ash, collapsed buildings, and destroyed vehicles before gathering in the air.
The sight was magnificent.
Millions of crystal cores of different colors formed several rivers above City S.
Chu Miao sent them directly into large purification pools inside the Soul Ring.
The pools had been prepared long ago for cleaning crystal cores collected from large zombie hordes.
As the crystal cores fell into the diluted spiritual spring water, black impurities spread through the pools before being purified.
The process continued for almost two hours.
By the time they finished, every part of City S had been searched at least twice.
Chu Miao and Ye Xuan met again on top of a partially collapsed building.
