Witnessing this scene, the shadow formed by the Blood Nether's Heart couldn't help but change facial expression drastically, suddenly striking at the Sky-covering Demon Emperor.
At this moment, endless demonic energy surged, instantly hiding the shadow.
Blood light suddenly appeared, the shadow rushed out of the demonic energy but was blocked the next second, endless demonic energy and blood light collided madly.
Every part of the Sky-covering Demon Emperor's body turned into a battlefield, and the most terrifying place of the battle wasn't the mind, but the heart.
Now, within the heart of the Sky-covering Demon Emperor, countless Supreme Chains swept out, tightly binding the Blood Nether's Heart, the supreme sealing power erupted, and the scary sinister Demon Fire ignited on the chains, intending to completely refine the Blood Nether's Heart.
