Seeking Immortality Starting with the Classic of Mountains and Seas

My name is Cheng Zhi, and I never believed in gods or Buddhas. Until... after I was reborn, I inherited a mysterious museum. After that, I saw the legendary elixir that could bring the dead back to life and restore flesh to bones; I saw the lost divine sword Xuanyuan; I saw strange beasts and ghosts running all over the place And that's when I realized something. As the saying goes, a gentleman does not speak of the strange, the supernatural, or spirits. Believe, and they exist. Disbelieve, and they do not. And I, Cheng Zhi, will slay demons and seek the Dao.
