Rule Horror: I Survive by Finding Bugs

On the night the rules descended, Jiang Xing was playing an obscure puzzle game on his phone. The reward for beating it was a single line of text: Rule 001: Do not look in a mirror after midnight. He thought it was a junk pop-up and tried swiping it away three times, but it wouldn't disappear. At 12:07 a.m., screams erupted throughout the entire building. A resident across the way was looking in a floor-to-ceiling mirror when his neck began twisting backward. The security guard downstairs was using his phone's front-facing camera as a mirror when his face split down the middle. Jiang Xing stood in front of the bathroom mirror for five minutes and found a way out that no one else knew. This isn't a game. But thinking like a gamer can save your life. The rules have descended, and there's no turning back. The only way to survive is to be even more unreasonable than the rules.
