校園裡的荷花池裡有很多烏龜，傳說只要外掃的時候有請烏龜吃點心，當天的考試就會很簡單。421Please respect copyright.ＰＥＮＡＮＡwIdGwWLEXn
一天晚自習時，你走出圖書室，看見一隻烏龜躺在石頭上休息，你給了他一塊方塊酥，他吃完便開心地穿越你的雙腳，來到池邊的一座雕像。你跟著他，發現雕像後方竟然有一道鐵門，打開，順著潮濕陰暗的階梯往下，來到一個巨大的鐘乳石洞。421Please respect copyright.ＰＥＮＡＮＡKDJeDLFMf0
鐘乳石洞裡，停泊著上百艘的潛水艇，看起來都有些生鏽，應該是戰前的產物。421Please respect copyright.ＰＥＮＡＮＡTCQv71ZDiz
突然，背後的鐵門被用力關上，鎖心輕響。421Please respect copyright.ＰＥＮＡＮＡ16PpbxooYx
有人把你反鎖在這黑暗的空間。421Please respect copyright.ＰＥＮＡＮＡVpKwxuoep9
