In the age of myths and legends, there were ten suns in the sky. The entities of these ten suns are ten golden crows with three legs. They were supposed to take turns bringing light to the world in the four seasons in a fixed order. But one day, ten suns decided to appear in the sky at the same time. On this day, trees withered, rivers dried up, humans were burned to death, and the world was like inferno. To prevent such a tragedy from happening again, a descendant of the ancient hunting god named Yi determined to kill the suns.
