"Hmm, who's there!" Tangyu and Qing Ge almost simultaneously lifted their gazes and shouted towards the outside of the room. As Huangfu Jing's personal bodyguard, Qing Ge always maintained high vigilance, and nothing could escape his notice once there was any movement. Qing Ge quickly rushed to the doorway, his eyes blazing as he scanned the outside, but he didn't find anything. Tangyu also rushed out, his eyes focusing on a certain direction. Tangyu felt that the fleeting presence had come from that direction. Moreover, this presence felt strangely familiar.
"A master, already undetectable so quickly—who could it be?" Qing Ge slightly furrowed his brows, his gaze sharpening.
"I'll go check." Tangyu hesitated for a moment before heading out, with Qing Ge initially wanting to stop him. However, at that moment, Huangfu Jing walked over and signaled Qing Ge to let Tangyu go. A trace of intrigue flashed through Huangfu Jing's eyes.
