Focusing on the universe ten years after the end of the war, under the surface peace, the forgotten galaxies have the residual energy of death. This energy combines with the negative emotions of the star beast to form a hidden shadow, which will subtly erode the consciousness of life and destroy the bonds of civilization. After Xingying noticed the anomaly, she joined forces with Chen Mo and Lin Xia to convene the Stardust Alliance and the Star Beast Clan to jointly build an "emotional balance network." In the end, by monitoring shadow fluctuations and channeling negative emotions, the crisis was resolved, interpreting the ultimate truth of the universe that light and darkness coexist and bind to protect peace.
