All women, from twelve-year-old girls to eighty-year-old women, grow the same organ at the same time: a set of shark-sharp teeth that can be controlled independently.
On the way to get off work, Lin Xiaoyu passed by a newly opened "Occlusion Gym" with a billboard that read:
"Strengthen your bite! 30-Day crash course, including instruction and skills!"
The male beauty salon next door hung a banner:
"Customized anti-bite protectors, titanium alloy lining, comfortable and safe!"
Teeth were never just for chewing—their oldest function was always biting.
