I can imagine that in that ancient century, the balance between gods, humans, and demons was broken.
As a result, the roses withered early, and the clear river water was dyed red with blood. The golden sunshine no longer shines, and people's hearts are covered by the haze of fear.
People begged the goddess to give them rain to wash away all their sins.
The goddess agreed and the rain fell, but people's hearts could no longer be washed away by the rain.
Before all evil is purified, the seeds of greed, desire, jealousy, and regret have already been planted in people's hearts. The seeds of sin are quietly planted, waiting for a period of time for luck to grow.
The humans that the goddess saved with her own hands are now frantically sucking the blood of their own kind. Tears fell from the corners of her eyes, but she still couldn't wash away the sins of thousands of years.
At this time, there are always some warriors in the three realms. Regardless of race, they have good wishes in their hearts and fight against all evil.
They are children of light, warriors with the golden feathers of the goddess in their mouths.
They are known as the Saints.
