They dared let her go wash the items because the racket they had made fighting the wild boar was so loud, and they had run such a great distance, that they believed any nearby beast would've either bolted away or been scared off by now.
So they felt somewhat reassured.
"I got it," Chiang Xiao called back, her mind suddenly stirring. Could she take this opportunity to see if she could catch a few wild rabbits or something similar?
Plus, she hadn't been to that patch of woods before. She could sneak further in and have a look around.
As for washing the items, she had previously considered whether to water the herbs in her Space, so she had already carried a small bucket of water there. If she ran out of time, she could just use that water to wash the items.
With a plan in mind, Chiang Xiao immediately crouched down and silently sprinted towards the distant woods.
The woods were on a slight slope with a thick layer of fallen leaves carpeting the ground, all was silent.
