Chapter 380: Chapter 380: The Only God of the Divine Dragon Empire

"What kind of sword force is this, so terrifying like this?" The experts of the Unparalleled Emperor Kingdom, looking at the Ancient Divine Cave Mansion, all had faces filled with fright.

As the Sword Qi of thunder in the great hall grew stronger, the thirteenth Sword Heart became more solidified, and the power of the sword became more overwhelming. Above the Thunder God Cave, lightning condensed into several Thunder Dragons, the terrifying pressure suffocating the experts from various sects.

Inside the great hall, the thunderous Sword Qi filled the entire space.

This thunderous Sword Qi, at times violent, was like a nine heavens thunder beast roaring through heaven and earth, and at other times extremely docile, like a breeze caressing one's face.

Time passed by.

The thirteenth Sword Heart finally became completely solidified.

The nine-colored sword aura bloomed.

Heaven and earth shook.
