He now had to ascertain the rough position of the ancestral court. He still knew nothing about it and the exact spatial geographic data of the four poles, Xuandu, and the abyss of the Ruins of End. He also had to ascertain the exact spatial coordinates of the dimension of where the Dragon Han Celestial Heavens was previously.
Only then could he precisely locate the ancestral court.
One could use the data from the Spirit Energy Mutual Shift Bridges for the spatial geography of the four poles, Xuandu, and the abyss.
The Spirit Energy Mutual Shift Bridge was designed by Qin Mu and black tiger god, and one needed different spatial geographic data for the bridge to connect different worlds. Thus, it wasn't hard for Qin Mu to obtain such data.
It was just that no Spirit Energy Mutual Shift Bridge was connected to the abyss of the Ruins of End. Even if there was one, it was probably in the hands of Celestial Empress and Yuanmu.
