Before the sisters left the house, they had informed their mother about Ji Nuan's cards and even told her about the conditions that had to be fulfilled in order to obtain this card.
When Ji Nuan's aunt heard this, she was flushed with joy. She told them to go shopping first and planned to ask their neighbors about the best properties available in Ji City. They were going to move into a brand new home. With so much money, they would at least be able to buy the biggest home available in Ji City's central area. If one wasn't sufficient, they would buy two; one for Sisi and one for Keke in a location near to their university.
In the end, these sisters did not manage to spend even a single cent with these cards. Instead, because they had taken a cab to come here in a fit of excitement, they had spent a large sum on the cab fee and their lunch. And it all came from their own wallet.
At last, the final black card could not be used after three, incorrect attempts.
