In an instant, Ye Xiaolei fell silent, a trace of sorrow flashing through her eyes.
At this moment, Ali, who was standing by the window, said, "Turn off the lights."
Qian Shanxue was taken aback.
Feeling a stirring in his heart, Shen Qiang immediately turned off the lights.
The room instantly turned dark.
In Shen Qiang's Divine Sense, he clearly saw a bottle of spray appear in Ali's hand.
"Ali? What are you doing?" Just as Qian Shanxue was asking, Shen Qiang saw Ali already pressing the spray in her hand.
Ye Xiaolei sniffed lightly and immediately exclaimed, "Luminol."
Qian Shanxue was stunned and said, "What does it mean?"
Shen Qiang raised an eyebrow and said, "Luminol, also known as luminescent ammonia, emits blue light when oxidized. Hemoglobin in blood helps transport the oxygen we inhale through this protein to all parts of the body."
