After the death of Jiutian Kuixing, the resentment condensed into the strange "Guijia". This object does not belong to the category of humans, ghosts, demons, or demons, but it can penetrate the nine realms of Jiutian, travel between Yin and Yang, and can even assimilate living creatures into the same kind, becoming a lingering shadow on the Jiuyuan land.
Shen Jingchen, the illegitimate son of Shen Xiaochuan, the commander of the Imperial Guards of the Dachang Dynasty, deliberately disguised himself as the notorious prodigal son in order to survive in the turbulent city of God. In an accident, he broke into the alien world outside the court and the Jianghu, and also learned about Guijia's existence.
Princess Lingxi was abducted mysteriously, and a "Jiuyuanjian" note forced the new consort Shen Jingchen to set foot on this mysterious land. On the road ahead, the overt and covert struggles of the eight major sects of the rivers and lakes, and the strange and unpredictable events of the twelve different sects follow one after another. In the entanglement with various forces, Shen Jingchen gradually discovered that he was inextricably linked to Guijia. From a pretender in Shendu City to an explorer in Jiuyuan Land, he moved forward step by step, uncovering the truth in the fog and murderous intent, and eventually grew into a legend that towered over heaven and man.
