Chương 256: Chapter 253 Vulnerability_1

Zhou Ning walked up to the laboratory door.

Just as he raised his hand, the lab door opened, and a young man, seeing Zhou Ning, quickly nodded at him.

"Doctor Zhou, what brings you here?"

"Is Mrs. Cui around?"

The young man stepped aside, and Cui Lili came from behind him, her face wary upon seeing Zhou Ning.

"What are you doing here? What's this about, another big batch of tests?"

Zhou Ning felt somewhat embarrassed and shook his head slightly.

"No, Xu Da is in a bit of a rush. These cigarette butts we sent in before, I think we can compare them to the other butts we found earlier. Prioritize those from the same brand, it'll make things much easier."

Cui Lili slapped the young man on the back of the head.

"Didn't you hear? Hurry up and sort it out. I don't smoke; how have none of you noticed this?"

The young man zipped away quickly, leaving Zhou Ning feeling embarrassed.

"I won't bother you any longer, Mrs. Cui. Can we have the results by noon?"

Cui Lili humphed twice.
