This is not nonsense; Wu Jiang has indeed encountered this before.
Boss Jing is known for more than just having a big appetite; her ability to quickly and perfectly handle such tricky emergencies is why Wu Jiang, a local bigwig, would lower himself to ask for help.
A skilled person is welcomed anywhere.
"Alright, it's not a big deal. Pick some quick-handed people, and with lots of practice, I'll teach them some techniques; there won't be any problems."

Jing Shu nodded as a matter of course: "How else would you do it? Testing on animals doesn't cut it. Back when we encountered a sea of ticks in Sichuan, countless soldiers had ticks burrowing into their bodies. That's when I honed my skills."
"Huh? Using people's bodies as tests, wouldn't that be too cruel?"
