Take the Supermarket to Cultivate Immortality

"Hey, the supermarket system has been started. What products does the host need?" "Hello host, I feel like you are overthinking. As the name suggests, I am just a supermarket. I have whatever is available in the supermarket before you traveled through time. Moreover, there are only so many goods in total, and there is no way to replenish them." After traveling to the world of cultivating immortals, Lin Qiuran thought she could unlock the invincible golden finger, but unexpectedly it turned out to be a useless system with only modern products, and she was also the least qualified Huang-level spiritual root. See how business prodigy Lin Qiuran uses a useless system to reach the top of the world in the world of immortality. This novel and its characters are purely fictitious.
