Yi Lin smiled without speaking, just squatted down and gently caressed the area near the bloodstain with her finger for a moment.

Yi Lin laughed and said, "Perhaps saliva? Without any instruments to analyze it, who knows?"
The two girls fell silent.
Suddenly, Sweetie let out a long sigh, "I think we should cooperate, instead of constantly scheming against each other like we usually do."
