Furious Iron Fist 2 Locked Room Horror

My novel revolves around a theme of the horror secret room, and it is related to Furious Iron Fist 1, and it is an adventure. The whole story is indispensable with history. Even if there is a new story and a new plot, the secret room is indispensable. Just like horror games, they just have to escape. This is the same style as that. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
