Spiritual Qi Is Disappearing Worldwide, but I'm the Only One Paying to Cultivate

Zhang Hao transmigrates to a parallel world where supernatural powers once existed, bringing with him a golden finger System that lets him cultivate by spending money. Overnight, every supernatural human loses their powers, but ferocious beasts and disasters remain, and humanity struggles to survive. As the only supernatural being left, Zhang Hao can grow stronger simply by spending money to recharge. (A feel-good power fantasy)
