Inspecting the rock for a moment, Di Tou couldn't see anything special about it, but knowing that it was something Huang Shu had left behind for him, he felt like it'd be wrong to just throw it out. In the end, Di Tou left it to the side for now and decided to wash it before figuring out what to do with it.
In any case, even if there wasn't air inside of the Spatial Ring and the stink couldn't smell, mentally, he couldn't accept putting it in his Spatial Ring. Perhaps it was a little petty and misophonic of him, but Huang Shu's stink really was something else, and he didn't dare to play around.
Looking around and seeing Huang Shu was gone, Di Tou was a little sad, although he was mostly glad the d*mn creature was gone. Every time he ran into it, he never seemed to have the upper hand and ended up in trouble.
