When Supreme Invincible's words fell, everyone couldn't help but draw in a sharp breath.
A middle-grade Dao artifact, what concept was that? It was on par with a Fifth Stage existence, only God Transformation Honorables were able to fully unleash the might of a middle-grade Dao artifact.
Not all God Transformation Honorables possessed a middle-grade Dao artifact; for example, Venerable Houde didn't have one.
A middle-grade Dao artifact must possess an Artifact Spirit. As long as there was enough Spirit Stones, the middle-grade Dao artifact could autonomously exhibit Fifth Stage combat power.
That meant that Supreme Invincible's first and second betrothal gifts combined equated to a Fifth Stage combat force.
Yu Qingtan had seen middle-grade Dao artifacts, including the Myriad Beasts Secret Realm's Thousand Beasts Mountain, the Blood God Cult ruins' Blood God Mountain, the Canglong tribe's Canglong Gate, and the Wendao Sect's Ten Extremes Disc.
