Super Fast Delivery in the World of Cultivation

Lu Nanxing is an ordinary courier in the world of cultivation. He lives at the bottom of the world. Although he keeps delivering food every day, his income can only meet the basic requirements of life and cultivation. It is almost impossible to become stronger. Suddenly one day he awakened to the system "using poison as a medium, a nine-liang scale system". As long as you are poisoned, you can use the system once. Every time the items delivered are expensive, you can get a tenth of them if you pass them. From then on, various cultivation resources were randomly selected, including those that I thought of, those that I didn't expect, those that I wanted, and those that I didn't want. Lu Nanxing stood on the top of the clouds and looked up to the sky and roared: "Why don't you, man, ride a divine beast and send it across the nine heavens? Drunkly ride the flowing clouds through the purple mansion, and carry the fairy wine with a smile to feed the immortals!"
