A group of people turned their gaze upon hearing the sound, and Tian Zhiliang twisted his body to stand up and greet: "Director Song, what brings you here?"
As Tian Zhiliang stood up, he casually tugged at Lu Cheng's sleeve. When Lu Cheng stood up with him, he introduced, "Director Song, this is Dr. Lu Cheng from our department."
The visitor, in his fifties, with graying temples and a serious expression, turned around: "Come with me."
Lu Cheng and the others were all confused, and Tian Zhiliang quickly followed, quietly asking, "Director Song, what's going on? Lu Cheng is on duty today."
"If he's on duty, then cover for him for a while. I'm asking you to cover for him for a while, can't you?" Director Song's tone was noticeably displeased.
Tian Zhiliang's mouth opened and closed twice, and he decisively nodded: "Okay, Director Song."
