A reflection appears in an abandoned university building. The rain in September always carries a musty smell that cannot be washed away. Deng Yushun stood under the eaves of Dormitory Building No. 3, Watching the dense rain turning the abandoned school building opposite into a blur of gray. The small building with red brick walls was like a forgotten scar, embedded in the dense green shade of the sycamore trees. The ivy covering the walls swayed in the wind and rain, like countless scratching hands.
