Weird Blind Date, the System Made Me a Brother-Supporting Demon

Just half a month ago, he had a soft heart and helped a beautiful young woman who had fallen down, only to find an unexpected encounter coming from the sky, bound to something called the Weird Blind Date Critical Strike Cashback System. The rules of this system are extremely outrageous. If you want to trigger the critical strike cashback, you must get to know the target through a blind date, and the blind date must meet two hard conditions: first, the overall appearance value must be above 70 points, and secondly, the target must have a younger brother, and the support value of the younger brother must exceed 60. Only by meeting these two points, Cao Kun can get the system's critical hit cashback by spending money with his brother-in-law. To put it bluntly, he is relying on being a "brother-supporting demon" to step on the road to greatness. This novel and its characters are purely fictitious.
