When she focused on her work, she would unconsciously purse her lips slightly, her jawline refined and distinct, giving her delicate face an extra sense of aloofness.
She pinched the instrument, maintaining the perfect 45-degree angle with the petri dish, just as Professor Bian had just described.

Professor Bian's expression stiffened for a moment, then he quickly started staring at the monitoring screen.
The image on the monitor showed the entire process of Xia Ye's experiment, which looked the same as what she saw through the high-power microscope.
Xia Ye inserted the ultra-fine injection tip of the instrument precisely into the tissue fluid, her movements clean and decisive, without any hesitation.
Professor Bian nodded in surprise.
