Seven Days in the Haunted Ruins: A Doomsday Puzzle of Infinite Loops

When the hands of the bronze pocket watch return to zero counterclockwise for the third time, Lin Jing watches the blood moon rise again outside the window and finally confirms that he is trapped in a seven-day loop on the eve of doomsday. The mysterious bone fragment sent by the archaeological team is beading with blood, while a recording made before his father's disappearance captures a voice that does not belong to a human being. The carved writing that gradually emerges during each loop will guide him into 13 forbidden zones shrouded in blood mist, where he must piece together the doomsday equation left behind by ancient observers. Every puzzle solved brings him one step closer to the truth; every piece collected sends him plunging another fathom into the abyss.
