Urban Mortals Cultivation to Immortality: the Path to Immortality in the Mortal World

The modern city is the outside, and the world of immortality is the inside. Hidden in the city are ancient martial arts families, secluded sects, demon cultivators, spiritual cultivators, and ghost cultivators. The aura is thin but contains spiritual veins, secret realms, and treasures of heaven and earth. Mortals don't know the immortals, and immortals don't disturb the mortals. The male protagonist breaks the boundaries and enters the path of immortality in his mortal body.
