He took the thermos from her hands and held it for her.
"I called you, but you didn't answer, so I called your roommate. Your roommate said Professor Li had called you and you hadn't returned yet, so I came to check on you."

Jiang Yue said, "My phone ran out of battery. There was a problem with the professor's research, and he asked me to help check it." Lowering her voice, she added in a volume only he could hear, "Someone was following me."
Xue Yan also lowered his voice, "I noticed."
"Did you see the face?"
"No, it was too dark," Xue Yan replied without looking back.
