Idealist world.
Yu Liang slowly chewed on these four words in his mind, trying to find their true meaning.
Everything here was either conjured by his own imagination, or perhaps his thoughts could prompt changes in the room's future.
If it were the former, then the most correct thing for him to do now would be to open the gate of the house, because the world was a figment of his imagination, and that was the most likely way to escape.
If it were the latter, then his thoughts were influencing other players in reality, making them think of this solution under the control of an obscure force.
Either way, they both pointed to a common conclusion, which was to open the door and search for the heart-stealing creature.
Of course, if he really were to leave the room, Yu Liang would certainly choose to let the Little Paper Men out of the house first to see what the world outside was like and whether the heart-stealing creature actually existed.
