Heaven's Light, Earth's Calamity

Suddenly, nine extra suns appeared in the sky. Living beings everywhere suffered through natural and man-made disasters, enduring untold misery. Yao, leader of the tribal alliance, led the people in trying every possible way to dispel the calamities, but nothing worked. It turned out that the nine suns were part of a colonization plot by an evil interstellar civilization. Faced with powerful alien technology, humanity continued to explore, and at last, through the joint efforts of unknown forces and Yi and the others, destroyed the extra suns in the sky.
