Cast Out by My Family, I Opened a Restaurant Selling Yin and Yang

[I'll update this once I'm done with the neighbor's thousandfold cashback story.]

In her senior year of high school, Xu Jing found out that she'd been switched at birth.

Her birth family took her back, but she was unwelcome at every turn. Her biological parents loved their fake young master more than anything, and all they had for her was blame and abuse. They even forbade her from coming home again for the sake of the fake young master.

With the ten thousand yuan they'd given her to sever their family ties, Xu Jing turned around and went back to the hometown where her adoptive parents had once lived.

To her surprise, she accidentally activated the Book of Life and Death, Yin and Yang!

[Hello, Host. This System was formed from a lost fragment of the Book of Life and Death, Yin and Yang, which escaped from the underworld into the human world.]

[The System chose you as its Host because you were born at the boundary between yin and yang and were severed from both your closest family and your blood relatives.]

[Whoever holds this book can see people's remaining lifespans, judge life and death, pass between the worlds of yin and yang, and serve as an agent of impermanence in the human world.]

[Special notice: Your current virtue value is zero. The System's basic functions, "Yin-Yang Eyes" and "Lifespan Sight," have been activated.]

Three days later, an unremarkable little diner opened...

All who are fated to find us are welcome.
