Under the bustling modern city of Jianghai City, there is a "Zhan Dao" system of cultivating immortals that has been passed down for thousands of years. Legend has it that the ancient Tao-killing emperor used a sword to prove the Tao, and integrated the Tao of "cutting all obstacles in the world" into the urban fabric of reinforced concrete. A hundred years ago, the end of the Dharma era came, and the spiritual energy receded. The Zhan Dao lineage was forced to go underground, forming a three-way separation with the emerging technological martial arts, the ancient martial arts family, and the extraterritorial demon sect. The protagonist Su Xin, as a contemporary successor of Zhan Dao, awakens the memory of his previous life at the node of spiritual energy recovery, and discovers that he is actually the eighteenth reincarnation of Zhan Dao Emperor. In this life, all forces are engaged in a bloody battle for the "Zhan Dao Sword" that can restart the spiritual veins of heaven and earth.
