Want to Get My Elixir for Free? Dual Cultivation Comes to Change You!

Lin Fan thought that his path to becoming an immortal had come to an end, and he even thought of a way out to retire from the world and marry dozens of wives. Until the senior sister who always liked to buy his pills for free came to visit again. He casually mentioned a "special reward" and accidentally activated the [Dual Cultivation System]! Since then, his alchemy skills have skyrocketed, his cultivation has skyrocketed, and he has no time to refine elixirs at will. The elders of Jindan are rushing to accept him as their disciple. The top-notch Binglinggen senior sister, the scheming little junior sister, the most beautiful woman from the outer sect... Came to her door one after another. Others can't build a foundation after hundreds of years of hard work, but he only needs one transaction to soar into the sky.
