Noah's Game: on the 536Th Day of Being Locked up in a Sealed Room, There Was a Dead Head on My Computer Desk!

If you are given 1 billion, the condition is to stay in one room for the rest of your life. Would you like to? I had accepted the rules of the game. After 555 days in the room, I decided to escape. Because this game is a trap. This incident has to start from the 536th day when I was locked in the room, when a dead head suddenly appeared on my computer desk.
