The black fog spread to the recycling factory just as Chen Qing finished tidying up.
She took out two gas masks from under the table, putting one on Daliya and sending the other to Grandma Taozi.
Chen Qing also helped Daliya into a full set of protective gear on the side.
Aside from being smelly, the black fog wouldn't actually harm people in any way; it was just a prank device, after all.
However... the stench from the black fog would cling to one's body and linger for a long time.
"Sister, aren't you going to wear one?"
Daliya obediently hid inside her protective suit and looked up to ask.
"No need."
Chen Qing shook her head, the stench would stick to a person's skin, and the stench in the black fog would be purified by the human body, so wherever there was stench, there were people.
The stronger the person was, the more they absorbed, and... the smellier they became.
