Demon Lord: "????"
The Thunder Hammer suddenly appeared at the back of the Demon Lord's head, leaving him momentarily stunned.
Right after, the Demon Lord thought of the power of the Heavenly Emperor of Returning Ruins' magical treasures.
Let's put it this way, the hardest part of the Demon Lord's body is his skull.
The Demon Lord can be said to be an invincible iron-head kid across the cosmos, above and below the heavens.
Previously, when the Heavenly Emperor of Returning Ruins and the Yin Celestial Son joined forces, they attempted to split his skull open.
Unfortunately, it was simply impossible.
After that, they targeted the tentacles of the Demon Lord.
The Demon Lord had actually encountered the power of many of the Heavenly Emperor's magical treasures directly.
In the Demon Lord's eyes, even at the peak of his powers, the force of these magical treasures was just that.
