I Had No Intention of Becoming an Immortal, but My Family Is Rich

I had no intention of becoming an immortal, but I awakened to the system of spending money to become an immortal. The more you spend, the higher your talent; The harder you spend, the more stable your cultivation will be. I struggled at first, wanting to cultivate on my own. But the system says: "If you don't spend it, I will deduct all your cultivation." I had no choice but to spend money like water with tears in my eyes. Later, I stood on the top of the fairy world, overlooking all living beings, and said with emotion: "This journey is all due to my persistence and hard work."
