Qi Jin was once the youngest star core guardian of the galaxy, but was stripped of the star core in a betrayal and became a wanderer in the ruins. His former best friend Yu Yao ascended the throne, holding a star core and commanding thousands of ships, calling him a traitor. When the galaxy fell into a doomsday devoured by insect waves, Qi Jin reorganized the remaining soldiers in the dark, using his flesh and blood as a guide to awaken the remains of the ancient annihilated civilization. And Yu Yao finally discovered in the severe pain of the star core's backlash that the real star core never belonged to the throne, but only belonged to the person who was willing to burn everything for him.
