Chu Luo nodded and said to him seriously, "You said that you were a little tired, so you closed your eyes to rest during the blackout."
Professor Chen believed Chu Luo and was about to stand up when the door was pushed open.
Nangong Yi and an archeology student walked in.
The student apologized to Professor Chen and Chu Luo the moment he entered.
"Professor Chen, Chu Luo, I'm really sorry. I didn't know that there was someone else inside. I thought that the professors had gone out to work and that you wouldn't come tonight. I studied till late in the classroom tonight and subconsciously closed the main power switch when I left."
Chu Luo asked strangely, "Your school will especially close the main power switch at night?"
