From afar, Bai Jiuyou immediately concealed herself upon spotting Shen Mingjing for the first time, because in the Heavenly Spear Realm, Shen Mingjing knew Bai Jiuyou was at Late-Stage Nascent Soul Cultivation and knew she was allied with Jiang Yuebai.
However, when discovered by Jiang Yuebai, Shen Mingjing was on the Xiong Family's tower ship, conversing with the Great Elder Xiong Yanqing, surrounded by a Sound Insulation Barrier.
Compared to sound transmission, the Sound Insulation Barrier is less effort-intensive, though it insulates sound without blocking sight, so Jiang Yuebai could see.
In this vast Upper Realm, many people wouldn't meet for decades, even after an initial encounter, so Jiang Yuebai never expected to run into him here so soon.
