Great Merit: Saved the Goddess Doctor at the Beginning

If someone else wins the system, they will either spend money or their combat power will explode. It's my turn, is the system forcing me to be a "lucky boy"? You can't spend money on yourself, you have to do good deeds! But when I spent my last 83 yuan and 60 cents on buying steamed buns to give away, and 8360 yuan was instantly credited to my bank card, I knew that the world was about to change. Merit can not only be withdrawn, but also life-extending, luck-changing, and skills can be purchased in the later stage! This is not a system. This is asking me to give the world "krypton gold"! Story background: A modern city, calm on the surface, but undercurrents surging inside. The protagonist, Lu Chen, is an unlucky guy who has just been pushed to the ground by life and is about to start a new life.
