Workplace rookie Wang Cuihua unexpectedly finds herself inside the plot of a transmigration novel, where she meets Zhang San, another time-traveler. One is a novice struggling to fight against fate in the workplace; the other is a domineering king who has spent ten years lying low, hiding his achievements. Together, the two, armed with knowledge of the script, begin a series of strategic maneuvers to survive. Tests confirm that the secondary female character, Xie Yong'er, is a transmigrator from an even lower level of the story world. Wang Cuihua and Zhang San prepare drought-resistant crops in advance, recruit talented individuals, stabilize the borderlands, and win over Xie Yong'er, all while defeating the Duke of Duan. Victory seems within reach, but Xiahou Dan (Zhang San) suffers from a long-term, incurable head illness. Only then does Yu Wanyin (Wang Cuihua) realize that the anonymous guest had long prophesied that only one of them could survive. Back when Xiahou Dan spared her life, he missed his best chance to survive. Now, Yu Wanyin makes the same choice to save Xiahou Dan. The weak Qiang Kingdom frequently sends assassins to defeat the Great Xia. When a mute assassin attempts to poison Xiahou Dan, Yu Wanyin uses poison to counter poison, curing his head illness and saving his life. In the end, Yu Wanyin and Xiahou Dan both survive, witnessing the prosperous era they had worked so hard to achieve.Adapted from the novel of the same name by Qi Yingjun.
