The clean-up operation indeed went very smoothly. Within less than one Lower-Domain day, almost all the Chaos Beasts had been killed. Only a small minority had managed to flee back to the Black Snow Sea.
The Black Snow Sea was extremely vast, and there were strong and dark undercurrents beneath the surface. Furthermore, the temperature in the sea was very low and grew even lower as one traveled. This was a huge impediment to martial artists' speed and made killing Chaos Beasts even more difficult.
Xiao Shan, Qiu Yi, and company decided to withdraw their forces and leave the remnant Chaos Beasts for others to kill via missions. The three pavilions' martial artists could slowly take their time to come here and wipe the Chaos Beasts out. The army started to pack up and collect all the Chaos Beasts' corpses to be handed to the higher-ups. Although some people—including Heaven Emanations—had died this time, the rewards were substantial.
