Knocking on the Immortal Gate: Immortal Life with Dry Bones

Mortals eat grain, immortals eat heaven. Gu Han was just the lowest medicine slave in the Immortal Sect Medicine Garden, his life was like a piece of grass and his life was precarious. In this world, elixirs can eat people, pill furnaces can refine people, and the so-called immortality is just a slow alienation. Some people become immortals and become demons. Someone ascended and became a ghost. Some people knelt outside Tianmen and kowtowed for the rest of their lives. But Gu Han just wanted to live. But later, he became the last person in the world to knock on the door of immortality.
