A Passerby's Story of Cultivating Immortality

Travel into the world of cultivating immortals in the book and become a passerby who receives a box lunch before appearing. I know the direction of the story in the book, as well as the fate and opportunities of the important characters, but my own future is completely unknown. Thanks to the ancient inheritance, I can build my own paradise of cave heaven, play around in the Immortal Cultivation Continent, and embark on the road to becoming an immortal.
