Modern young man Chen Fugui accidentally traveled to the Qin Dynasty, bound to the luck system, and fell into Liu Bang's lap at the beginning. He used modern wisdom to improve farm tools and skillfully set traps, transforming himself from a homeless man in Sishui Pavilion into the core counselor of Pei County's uprising. He conquered the descendants of the Mohist family and a talented woman in the medical field, outsmarted the powerful royal tombs, deftly defeated Zhang Han's pursuing troops, marched westward to outwit Wuguan, killed Zhao Gao in Xianyang Palace, and even survived in danger at the Hongmen Banquet, resolving Xiang Liu's death situation. In the troubled times, let's see how he uses his luck to bring a group of heroes to help Liu Bang compete in the world in the turmoil of the late Qin Dynasty, and write a legend of the grassroots rise of the Qin Dynasty.
