The sky literally started falling from the very beginning.

Years later, as time turned everything old, the world above and the world beneath were already in a desperate turmoil, with immortals descending to the mortal world, and gods and demons performed chaotic dances, making the lives of people unbearable.
Chen Chang'an stepped out of his seclusion one day, looking at the heavenly gods and buddhas scattered across the sky.

That day, he swung his sword and parted the heavens, ever since then, Heaven belongs to Heaven, Earth belongs to Earth!

Above the boundless Silent Death Sea, an appalling surge of mana continuously erupts, two matchless beings are immersed in a vicious slaughter.


Outside of the torrential carnage, four ancient Great Demon illusions each towering tens of thousands of feet tall span the area. They form together into a Formation, firmly trapping a man and a beast in this realm.

At this moment, the originally mildly calm boundless black Dead Sea suddenly boils uncontrollably.
