The Question of the Century

The door opened with a creaking sound.

The silent atmosphere of the lecture hall was chilling.

The venue seemed to have captured the chaos from yesterday. Papers were randomly scattered on the ground, even the chair he knocked over was still lying on the floor.

Lu Zhou thought back to yesterday, the scene that made his heart drop…

Seeing how Lu Zhou was staring blankly at the lecture hall, the assistant didn't want to disturb him. However, the assistant remembered his half-finished lunch, so he took a deep breath and said, "If you want to stay here for longer, make sure to close the door later. Do you want to key?"

"Sure."

Lu Zhou took the key and nodded. He said, "I'll return it to Professor Helge Holden, you can go."
