The middle-aged man in black, tapped his fingers rhythmically against the polished tabletop, while he contemplated. After a moment , his eyes flickered with a sudden, sharp intensity. "Elder Yuan," he instructed, his voice low and deliberate, "I need you to personally observe those children. Pay close attention to their movements, their habits, everything. More importantly, gauge the reaction of the Yang family to this incident. We must tread carefully, Elder Yuan. Do not, under any circumstances, alert the snake before the Yang family makes their move."

The old man hesitated, a flicker of uncertainty crossing his weathered features. "But Master," he ventured, his voice filled with polite inquiry, "Why such an intense focus on these children? They appear to have no direct connection to us. Even if they pique your curiosity, surely such personal observation is unnecessary?"
