Chen Lang time-travels to the chaotic Republic of China era, becoming a bottom-tier dock laborer in the Tianjin slum district. Unexpectedly acquiring the ability to cultivate in his dreams, starting from Baji Quan and progressing through Jin, Mingjin, and Anjin, he grows through a path of slaughter and battle, ultimately achieving the status of a Huajin Grandmaster at age nineteen. He shakes the Martial Arts Association, bombards the foreign concession, and shocks China under the moniker 'Human Demon.' Guided by Zhang Quezi, Gao Yue, Lu Changfeng, and others, he embarks on a 'Path of Startling Gods'—cultivating divine energy through combat, pursuing the legendary realm of the Danjin Grandmaster.
