The slightly urgent knocking suddenly sounded, interrupting Professor Yao's eloquent speech.
He waved his hand holding the pipe to the side: "—Come in."
The door of the conference room opened silently, revealing a slim figure.
It was Doctor Duzem.
"—I came immediately upon receiving your message." The doctor quickly glanced at the others in the room, a slight hint of surprise flashed in his eyes but was well concealed, he then looked at Professor Yao properly: "But you know, the construction of the No. 2 Prototype is at a critical stage, I might not have much time..."
"Won't take long, I just need about ten, twenty minutes from you."
