Starting from the Mental Hospital to Plan the Layout

(Top-level battle of wits, layer upon layer of reversals, climax in three chapters) In the mental hospital, they all look at you like you're crazy. They say you're mentally ill, but you know you're not. You looked down at the shadow at your feet, and it was ready to move, trying to replace you. Are you crazy, or is the shadow alive? Everything around you seems to be full of malice. Are you in it, or are you on the outside? Do you know nothing, or do you already have a plan? No matter what, Li Banguang, stay awake!
