Hand over to the immortal cultivation world

Modern office worker Su Xian soul-transmigrates into a cruel cultivation world. He lives relying on his younger sister Su Yu, until they are abducted by the Chusheng Demon Sect. Due to his inferior spiritual root, he is reduced to disposable low-level material. On the verge of death, he activates the Mysterious Mirror and makes contact with his motherland Daxia. Daxia immediately sets up a Special Regulation Bureau and launches the "Kunlun Void Project" to fully support his survival. With national backing and his sister’s secret help, Su Xian grows rapidly, yet incurs the hatred and persecution of Zhao Si, and gets entangled in the power struggle between old and new factions within the Demon Sect. He shares cultivation knowledge across realms; after Daxia conducts research, it feeds back to boost his strength. In the end, Su Xian unites allies to overthrow the old order, reshapes the Demon Sect’s rules, assists Daxia in opening an era of universal cultivation for all citizens, and establishes a passage connecting the two realms.
