Second Stage Mad Demon, World-Discarding Knowledge; One Sword Could Silence a Million Armies

"Yousi Sword could undergo Heaven's Liberation too?!"

Before the Dao Transmission Mirrors, sword cultivators across the Five Domains were on the verge of clutching their heads and screaming.

In today's battle of Sword Immortals, what had everyone witnessed? Two Chaos Divine Artifacts undergoing Heaven's Liberation!

Famous Sword Twenty-One could undergo Heaven's Liberation in every generation as well.
