Just as Duan Gantai was urgently looking for Ning Cheng, Ning Cheng was also eager to find Duan Gantai. It wasn't because he wanted to return the black Time Yongwang Key to Duan Gantai. Even if he didn't need it anymore, he would not be so selfless. That Time Yongwang Key was exchanged with Mo Xiangyi's wine; naturally, he would not simply return it to Duan Gantai, which was also the reason why Ning Cheng initially did not confirm with Duan Gantai how many Starry Sky Spirit Veins he wanted.
The reason he was looking for Duan Gantai was to find out whether Duan Gantai had the means to enter the Time Hall.
Ning Cheng had not expected that shortly after he came out of the Time Hall, he would sense Duan Gantai through the Binding Gods Filaments, and Duan Gantai was rapidly approaching him.
The place where Ning Cheng was located was not far from the Manlun Star Land; he simply headed towards the Manlun Star Land.
