The Divine Forge Rune Stones were similar to the poison created by the major authority of Poison.
How the Divine Forge Rune Stones would be used afterward had nothing to do with the major authority inheritor.
Moreover, Qin Feng could apply the effect of the Illusionary major authority when the Divine Forge Rune Stones took effect, just like when using the Cocoon of Weaving.
This way, if the Divine Forge Major Authority inheritor wanted to check related information, they would have to compete with Qin Feng's Illusionary major authority in divine essence influence. This would allow Qin Feng to learn about the other party's actions and gather more information.
