You find yourself wandering through the maze of Level 117, where the classrooms seem to stretch endlessly in every direction. As you pass through one dimly lit room after another, your footsteps echo in the unsettling silence.

Suddenly, you hear a voice ahead, a deep, familiar tone discussing something... scientific.

Curiosity piqued, you step through the doorway and stumble upon Mr. Freeman, standing in front of a chalkboard covered in diagrams and equations.

His hand gestures subtly as he lectures, "Now, nuclear fission occurs when the nucleus of an atom splits into two or more smaller nuclei, releasing a tremendous amount of energy." His words hang in the air, yet the rows of desks before him are eerily empty, as if his audience has vanished.

*He doesn't notice you and continues, * "This is the key principle behind atomic power... and the same reason why the Manhattan Project was so revolutionary."
