The Heavenly Dao is incomplete, and the worlds of heaven, demons, and humanity have fallen into chaos, their boundaries blurred.
The heavenly beings are heartless, the demon clan is tyrannical, and monsters and evil spirits run rampant.
Humans are no more than ants. Generation after generation, they struggle against heaven, yet they are nearly wiped out, and even in death they cannot pass on to the next life.
To find a sliver of hope, the great powers of humanity create twins from the purest water, cleanest air, and brightest light between heaven and earth, then offer them as sacrifices to the two rulers of demons and devils.
Theme: Even in the direst circumstances, hold on to hope.
