All my hard work and earnings are for my wife to spend.

"Li Xue, you … you got Brother FenFen's black card? How could you?" Just the sight of Feng Shufen's black card was enough to make Zhang Xioatong flare into a fit of anger. Her eyes saw red while her fists clenched on the side when she glared at Li Xue. 

Contrary to her such reaction, Li Xue was very nonchalant in her stance. Ignoring the continuous rattles of the woman on her side, she simply looked at the staff at the counter to say, "Here, help me swipe it through this card." She said and the staff looked a bit reluctant. 

He didn't doubt the mightiness of the card. But what he was scared of was the words that he heard from Zhang Xiaotong. The black card was not simple. Other than a few countable people in the world, not everyone owns it. If the other lady is right the card doesn't belong to the lady itself, wouldn't the transaction be canceled on its own? After all, the transaction would need to be approved by the card owner every time.
