Jiang Yi was reborn and returned to the system selection day. He saw clearly the plan of his best friend Liu Ruyan and decisively chose the consumption rebate system that killed him in the previous life. She is not greedy for selfish desires, spends money rationally, does charity, invests in talents, and plans for the future, and the more she spends, the richer she becomes. Liu Ruyan clings to the system of diligence and thrift, and is extremely stingy and spends her life. Jiang Yi relies on wisdom and kindness to break fate, gain love and career, and finally dissolve the system and live a free and happy life.
