After disposing of the bodies, Su'en took out a test tube filled with a green potion and dripped a few drops onto several pools of fresh blood.

This was a concoction commonly used by the Old Lingdun gangs to dissolve corpses and erase traces—【Blood-Melting Fungus】.

As the potion fell, the bright red blood was rapidly devoured by the bacteria, turning from red to fluorescent green before evaporating in the blink of an eye.

The last traces of the bodies were wiped clean.
