Pay to Raise, and the Sect's Saintess Becomes My Spirit Pet?

[Single Female Lead] [Fresh Premise] [Absolutely Worth Reading] My name is Chen Feng. I'm in the late stages of liver cancer and close to death when my phone suddenly installs a pay-to-win Daoist Partner Raising Game all by itself. I spend money to buy her cultivation techniques and magical artifacts. The astonishing thing is that her cultivation feeds back to me, and the game's items can be used in the real world. The stronger she gets, the stronger I become. Gradually, I become invincible in the real world.
