That being was the first life to emerge from chaos. Born with the power to create everything but rule over nothing, he was granted supreme glory and divine power by the Great Dao of the cosmos. He seemed to be the very embodiment of the Dao, yet he used that power only once.
Knowing the time had come, he opened up chaos, divided yin from yang and the clear from the turbid, and created all the divine realms across the heavens and earth. He knew a great calamity was approaching, so he commanded the Demon Kings to scour the ten directions and three realms. He created all living beings, then personally set their struggles in motion. In the end, he retreated to Human and Bird Mountain. At last, that god could bear it no longer: not his glory, not his cruelty. So that god decided to end it all with his own hands, in his own way.
Those Demon Kings were born from the six days of turbid energy that arose from chaos. They were powerful from birth, towering above all living things, proud and violent, immortal, and possessed of inexhaustible strength. When they came to the mortal world, they unleashed a killing spree. Wherever they passed, corpses piled up like mountains and blood flowed like rivers. Would they only stop once every living thing had been wiped out?
That god was formed from the three days of pure energy that arose from chaos. He could have lived carefree in the celestial realms, looking down upon all beneath the heavens, where worldly splendor was as fleeting as a dream. Yet he chose to descend to the mortal world to save its people and avert the calamity.
But what of insignificant humans? They had committed a monstrous crime. How should they live? When the great calamity arrived, would they rise up and fight back, or cling desperately to life?
It's very beautiful, very imaginative, very novel, and has all kinds of whimsical and whimsical plots.
