Let's See What Kind of World He Creates

"This is a ditch of hopelessly dead water Beauty can never exist here Better to let ugliness plow it over And see what kind of world it makes" -- Wen Yiduo, "Dead Water" Apocalypse, zombies, Sentinels and Guides Main couple: a beautiful, slightly tsundere Sentinel with an antisocial personality and ridiculously strong combat skills, top × a frank, lovestruck Guide who spouts innuendo and has off-the-charts combat ability, bottom Brian (No. 13) × Ning Chengyou The bottom pursues the top and dotes on him. Early on, the top is badly injured and stays in the form of a little kid, getting carried around by the bottom. He recovers later. Probably two side couples: one straight couple, a gentle, refined male Guide × a female Sentinel who can wear a thousand faces and knows how to flirt Qin Yan × Ming Xiao One BL couple, a rather straight-laced, hot-tempered Guide top × a Sentinel bottom who dotes on him without limit Cheng Yue × Yan Jian The author's theoretical knowledge is lacking, I have no common sense or logic, and my writing is terrible. All scientific details in the story are pure imagination. Please don't nitpick.
