Li Qiao had been immersed in the laboratory for days on end, barely stepping out except for necessary activities.
Their research project had made significant progress, with several common and uncommon arsenic compounds undergoing detailed arrangement and testing.

Li Qiao exhaled, slid to answer, "Dad."
Li Guangming's gentle voice came through, "My girl, are you still in the laboratory?"
"Yes, I am. Is there something you need from me, Dad?" Li Qiao rubbed her temple, her face clearly showing signs of fatigue.
