Sword Embryo Formation

He took out a jade scroll from his bosom. The jade scroll recorded the formations that each sword embryo needed to be engraved with and the method of refining it.

There was nothing special about the refining method. He understood at a glance.

His attention immediately focused on the four formations.

He had never seen these four formations before. Just this was enough to pique his interest. The jade scroll had detailed descriptions of these four formations.

Li Ming was dumbfounded.

This was a fourth-grade formation!

The four fourth-grade formations were all different!

Only now did he understand why Su had never found someone who could refine this sword embryo. Each sword embryo had to be engraved with a fourth-grade formation. Four sword embryos were four fourth-grade formations.

Moreover…

There was a mysterious relationship between the four formations.
