The Infinite Wealth System in the Divine Apocalypse

Story Description: The world ended when Earth merged with the legendary Azure Heaven Cultivation Realm. Monsters invaded, spiritual energy awakened, and countless people gained powerful abilities. Lin Tian was left behind as an ordinary mortal.
Just as he thought his life was over, he awakened the Infinite Wealth Goddess System. The system grants him endless money, but he can only spend it on women chosen by the system. Every goddess he supports grows stronger, while he receives cashback and mysterious rewards.
Unknown to Lin Tian, the system prevents him from seeing the true power of these women. While he believes he is helping ordinary girls survive, they are actually becoming Saintesses, Empresses, and future Goddesses capable of shaking the heavens.
As the apocalypse worsens and ancient immortals descend upon Earth, everyone begins to believe that Lin Tian is a hidden supreme expert manipulating fate itself.
The problem?
Lin Tian is still convinced he's just a normal guy trying to survive.
