This rocky wasteland was huge. With Zheng Nanxun's current cultivation, it would be a lot of work to explore the entire place.
However, in order to find the traces left behind by Jiang Qiqi, no matter how difficult it was, she was willing to overcome it.
Moreover, she was extremely careful throughout the entire exploration. Even if it was a small stone, she would carefully examine it to see if there were any information imprints.
Many times, the so-called traces were not necessarily visible on the surface.
Especially after one's realm was higher.
For example, the powerful will contained in a sword light might exist forever.
Most of the time, this will not cover a wide range. It would automatically condense in a smaller area or even on something specific.
Moreover, it was extremely hidden. Usually, unless one personally came into contact with that thing, it was very difficult to sense this remnant will information.
