No one knew that this seemingly ordinary world, full of the warmth of everyday life, had never been the real human world.
It was merely the abdominal cavity of a colossal insect.
A hundred years ago, Antarctica's ice wall shattered, and disaster descended.
Deadly poison swept across the globe. Red rain corroded the earth, and the old world fell completely.
To survive, humanity beyond the walls signed a brutal pact.
Every year, they sacrificed ten thousand infants, sending them into the world inside the Insect King's belly.
The infants' souls were pure. They would be raised as nourishment for the insect race and the elite who had been corrupted.
Yet the infants could also awaken the laws of the Sacred Domain under the influence of their environment.
And the vast majority of so-called "humans" were impostors, imitations made by the insect race.
They divided the cities into two worlds with towering walls. Outside, uncanny humans ran rampant; inside, things were even worse, a hell of depravity.
Lu Yao had been plagued by demonic afflictions since childhood, unable to sleep night after night.
He had doubted himself, but never the world.
Until the iron sword pendant he had worn since childhood grew hot against his chest.
Only then did the divine domain sealed within him fully awaken.
Lu Yao finally saw the truth and established himself in the human world with his divine domain.
With the divine domain, he would shatter the false world. Alone, he would defy heaven and earth!
