In the troubled times of the Republic of China, Nanyang was overturned. Mo Yungao led the Twilight Grass Poison Army to bloodbath the southern archives of the Zhang family. The huge intelligence stronghold was wiped out. Only the chief Zhang Haiqi and his subordinates Zhang Hailou and Zhang Haixia were left. They became fugitives and were endlessly hunted and driven into despair.
Everyone knows that the Zhang family has the Qilin immortal bloodline, but no one knows that there is a secret ancient family in the world that was born earlier - the Geng family of Shuyang Gaoyangtang. The Geng family possesses the heritage of the fourth piece of meteorite jade from the outer world, and has passed down the bloodline of Qinglong to extend life from generation to generation. Geng Haoran, the clan leader, has a combat prowess that rivals that of Zhang Qiling, the last head of the Zhang family. He holds the clan's divine weapon, the dragon stick, and is proficient in the art of earth veins and the reconciliation of all poisons. It has been passed down for thousands of years and has a solid foundation.
In order to protect her youngest son's safety, Zhang Haiqi used the highest authority in the archives to assign her two biological sons to the Zhang Jiahai generation, and hid them from the world under false names. She personally taught them the skills of fighting, disguise, and espionage, thus concealing their identities as legitimate sons of the Geng family. In the desperate situation, the dusty life experience was finally revealed: the two brothers who were on the run were originally the young masters of the Geng family, while Zhang Haiqi, who had been in charge of the secrets of the Zhang family for half her life and understood all the weaknesses of the Zhang family, was the mistress of the Geng family.
Zhang Hailou, the unruly and rebellious devil who gets into trouble wantonly, is naughty on the outside, but longs for his family in his heart. Seeing that his mother was poisoned with a strange poison and was on the verge of death, he put aside all his stubbornness and resistance, lost his frivolity, and gradually accepted his life experience. The calm and transparent Zhang Haixia has always taken care of the aftermath for his brother. The two brothers decided to join hands to enter the secret realm of the Geng family Xuan Shu, take the trial and seize the scroll, and officially return to their clan to recognize their ancestors.
