Sang Qianqian's heart suddenly stopped beating and her face lost all color. Everything in front of her eyes started to spin.
How could this be? How could there be nothing here?
"Qianqian, don't be anxious."
Xie Shi'an consoled her. "Let's look for it again. Maybe Professor Fu'er kept those things in another room."
This sentence gave Sang Qianqian a tiny bit of hope.
She tried her best to calm herself down and carefully looked through every nook and cranny in the laboratory.
However, they found nothing.
After the laboratory, Sang Qianqian went to the other rooms.
This small building had three floors, and there were more than a dozen rooms.
Sang Qianqian looked through each room once, but was worried that she might have missed something, so she looked through them a second time.
She even read the thick medical books and notes in Professor Fu'er's study.
