"The entrance has already been completely opened by Bai Huang. Apart from us, no one else underground should face any restrictions,"
Su Chengyu reminded Bai Qiu, who stood beside him.
Bai Qiu responded with a soft "mm," without further words, as she focused within the subterranean space to pinpoint Ao Tian's location. She understood that finding Ao Tian would naturally lead them to Bai Huang and the others.
Realizing what Bai Qiu was doing, Su Chengyu refrained from rushing her. He knew this was the fastest way to locate Yu Yanshu and the others.
