What Does It Mean That I Am Vigorously Cultivating Immortality?

Traveling to the world of "The Beginning of the Street Stall Sales Dali", others awakened to the most powerful street stall system, but there was only a shabby book in my mind - "Cultivation of Immortality". The first volume of "Nine Transformations of Mysterious Skills": Copper skin and iron bones, proving the Tao with strength. Jiang Nan drank powerful potions and became bald, while I absorbed spiritual beads to refine copper skin. Jiangnan sells detoxifying soybeans to earn resentment points, and I copy the bricks and help others open the scoops. There are spirit beasts, spirit ruins, and space superpowers in this world, but sorry, I am a cultivator. "Dude, your hair..." "Don't even think about it, my hair is worth 100 million." At the beginning of the game, he met Jiangnan and hit Wang Lin with a brick. Poisonous tongue + rich + tough and handsome, one person can eat enough and the whole family will not be hungry. I don't care about systems or anything else, it's enough for me to have books. Although this book seems... Not too serious.
