Capítulo 404: Chapter 404: Of Course, to Become My Woman!

The Heavenly Treasure Scroll!

Suddenly, Li Qianfan remembered something. Earlier, when he was browsing through the Heavenly Treasure Scroll, he had seen a description of this kind of black crystal stone.

Thinking of this, he immediately looked around and noticed that the students were washing up. Taking advantage of the fact that the group had not yet assembled, he quickly went to a corner and took out the Heavenly Treasure Scroll to carefully study it.

It only took him a few minutes to find the description of the black crystal stone in the Heavenly Treasure Scroll.

Black Pattern Stone!

This was an extremely rare crystal stone, containing a rich spiritual energy, primarily used in array formations to serve as the formation's focal point.

The strength of a formation is closely related to its focal point, and a formation arranged with Black Pattern Stones could be incredibly powerful.
