They are the ninety-nine kinds of talismans described in the book of talismans as the most destructive, requiring extremely high levels of engraving ability, soul ability, as well as comprehension of the Power of Law and realm to be engraved.

It wasn't until Mu Fusheng's Soul Nurturing Technique made another breakthrough, reaching the seventh level of Heavenly Sun Soul Fire, that these four abilities were finally met simultaneously.
