500 Yuan, and My Sister Sends Me to Work as a Maid?

In his final year of high school, Wen Xu gets a super app for his super phone.

The first app is Zhuanzhuan.

Anything his customers sell will belong to him. Once his sales reach 100,000, he unlocks the next super app!

Before using it:

"I can just find a few customers and have them sell some old phones. That should do it..."

After using it:

"What do you mean, customers are bound and locked in? Is this a beautiful girl so poor she's on the brink of ruin?"

"What do you mean I have to transfer my own twin sister to you?"

"My sister works and earns at least 5,000 a month. If she just keeps working like this for her whole life, that's 50 years, twelve months a year, so it should be 3 million... My sister should be worth three million."

"Your sister is worth 500 yuan. Are you trading her?"

"I am!"

"???"

"Not just my sister. I'll sell all the years I have left, too!"
