The interstellar god of war "Xinghen" fell and woke up in the dying body of Lin Wanxing, the real daughter of a wealthy family, and became Ling Xi. Carrying the original owner's obsessive contract of "repaying her benefactor and protecting family ties", she blended into the unfamiliar world of fireworks with cold rationality. The warmth of delicious food, the guilt of parents, and the sincerity of friendship melt the ice little by little. When she identifies Gu Xuanlin, a gentle yet dangerous person, as her childhood benefactor, her plan to repay her kindness becomes entangled in the whirlpool of family conspiracy. The blood-stained wrench, her mother's death, her adopted sister's betrayal... Surrounded by poisonous snakes, she formed a life-and-death alliance with Gu Xuanlin. From the trial game to the heart-to-heart connection, from side by side to break the situation to the love that determines this life. When the chip threat from her "hometown" emerges, she uses the stars as a tomb to cut off the past. The cold stars finally fall into the warm fireworks. Her return journey is the dawn light and the Xuanlin that protects the light until eternity.
