Gu Hengbo was as sage-like as ever. His clothes were of the same color as before, with no unnecessary decorations.
He had a straight and serious face. He didn't say much along the way and mainly listened to his students.
Until Ji Ziyin asked him about the Level 8 laboratory.
Gu Hengbo frowned slightly. "I've spoken to the person in charge of the Level 8 laboratory. He's still thinking about it and hasn't given me an accurate reply."
Ji Ziyin couldn't hide her disappointment, but she still smiled and said politely, "Thank you, Teacher."
