I Really Got Tens of Billions of Subsidies

Unexpectedly received a tens of billions subsidy system. The protagonist did not choose to take the road of being a powerful person, but chose to live a simple and unpretentious life, living in a better flat floor, driving a better car, and dating a younger girlfriend. This is what I thought and did at the beginning, but it won't necessarily change in the future. It all depends on whether the protagonist can change his original intention of ordinary life after experiencing some things.
