On the third night after my sister disappeared, I sneaked into the forbidden underground area of the orphanage. The rusty iron door was engraved with "Gate of Salvation", but the cry of my sister could be heard from inside. The psychology professor called it "mass hysteria" and warned me not to go any further. Until I was in the hospital morgue and saw the corpses of children whose happiness had been taken away from them. When the last door was pushed open, countless familiar faces emerged in the darkness - "Brother, we have been waiting for you to come home."
