In response to Du Lingfei's words, Bai Xiaochun's eyes glittered with surprise. Something seemed very odd with how she felt about the matter. When a daughter was in trouble, it was the most natural of things for her father to come help her, at least as far as Bai Xiaochun was concerned. However, he didn't say anything. As his body continued to recover, he grabbed her arm and pulled her along.
Adding the Undying Hex in gave them a bit more speed. When combined with the golden light of teleportation that Du Lingfei used, it gave them enough speed to at least flee from the laughing-crying ghost face, who was capable of speeds similar to the Celestial himself.
Unfortunately, despite being able to achieve speeds that surpassed the Deva Realm, they were still roughly comparable to a demigod, therefore, the ghost face continued to close in no matter what they did. Soon, they heard the sound of screaming winds behind them, as well as the shrieks of evil ghosts.
