[Bonus chapter]

When they returned back to their home, the first thing Yu Dong did was to clean the water vat behind their house. Earlier they caught so many fish but now they didn't have a place to keep them, she didn't have a bathtub of spring in her space, so she couldn't keep them there. And leaving the fish in the bucket would only make them stink more, so she cleaned the water vat with detergent and immediately filled with vat with water that was instilled with spiritual energy. 

Only then did she empty the buckets of fish that they didn't need right now.  Then she poured the snails that they caught in a large basin and cleaned them with salt and spiritual water. Cleaning snails was a tedious task but with her cheat trick, she easily cleaned the snails.
