Am I Poor? My Junior Sister's Pocket Money Is Enough to Buy a City

[Dragon and Phoenix male and female protagonists + pretending to be pigs and eating tigers + poor senior brother + rich junior sister] My name is Yunyin, the top disciple of Qingfeng Sect.

It is a treasure that the whole world does not know. As brothers and sisters, our greatest pleasure is to pretend to be pigs and eat tigers. She was the little pig that seemed harmless to humans and animals and only knew how to throw money at people, and I was the rustic pig that kept silent. This story started when I went to the foot of the mountain to make soy sauce, and met a blind second-generation fairy who insisted on snatching the new skirt my junior sister just bought...
