Seven Days of Death: After the Memory Is Reset to Zero, Rely on Logic to Defeat the Enemy

At midnight every day, the brain memories of all participants will be forcibly reset, leaving only the basic cognition before entering the game. Everyone is frantically grabbing three "10-word memory anchors" every day, treating it as the only way to survive. Only I know that the rules have left loopholes from the beginning - only the brain memory is reset, and the physical traces in the environment will never be erased. I am Lin Shen, a former top cryptanalyst. In this death cage of amnesia every day, I used a glass of water, a scratch, and the angle of a wardrobe to build an information chain across resets with myself for seven days. Rules are the way to kill the game, logic is the way to survive. I will definitely win this game.
