Vision Solver: Don't Let My Sanity Level Return to Zero

A sheep knocking on the door in the middle of the night? A floor you can't get out of? Someone who looks exactly like me? In a city full of strange phenomena, the Solver is the only hope. Li Huaien: "Yes, I'm a trainee. Is there any problem?" … "My emerald eyes have already seen the crux. I will blow it up for you in a moment. My hands can detonate anything." … "Look, it will be done soon, right? Remember to contact me next time you have such a request." … "Wait a minute, stay away from me first. There's something wrong with my eyes. My sanity seems to be dropping too fast... Run! Carry the high-speed rail and run for me!" (For some plots of Cthulhu, readers are asked to bring their own sanity mixture)
