章 735: Seed of the Heart Demon

The violent thunder continually reverberated out from the Thunder Magic Abyss.

Boom! Boom!

It had not even stopped for a moment. About a thousand people sat cross-legged in the sky, while dark lightning prowled around like a python. These people sat quietly, like rocks, and allowed the Earthly Demonic Lightning to attack them.

They formed the same seals with their hands. Then, dark lightning entered into their bodies through their pores, refining their bodies and bones.

Mu Chen sat cross-legged in the air a few hundred meters away from them. He did not close his eyes, but stretched forth one of his palms, which held the broken stone tablet that had been reduced to a smaller size.

He blinked and then shut his eyes. After a few moments, he then slowly opened his eyes, in a daze. He stared at the stone tablet in shock.
