Astral Pet Store (WN) - Chapter 20: Evolution

Two years ago, Nina married a man she had never met. She didn’t know his name or his age; she knew nothing about this person she was married to. Their marriage was nothing more than a contract with conditions, and one of the clauses was that she should not sleep with another man.

Yet, Nina lost her virginity to a stranger when she knocked at the wrong door one night.

With the compensation she had to pay weighing her down, she decided to draw up a divorce agreement on her own.

When she finally met her husband to hand over the papers, she was shocked to find that her husband was none other than the man she had “cheated” on him with!

Yao Mo Xin, the empress of Da Chu died in a cruel way a day after she gave birth at the hands of her husband the emperor, Ye Hong Yi, and her legitimate second sister, Yao Shu Ran. Ye Hong Yi got the throne because of the smartness of Yao Mo Xin, but he hated her because she made him feel like a useless person who needed a woman to become the emperor.

Her soul got in the body of her illegitimate third sister from the same mother Yao Mo Wan. Yao Mo Wan has the mentality of a child because the legitimate wife of her father fed poison to her mother while she was carrying Yao Mo Wan. Yao Mo Xin wants revenge for everything that happened to her, so she seduced the emperor and began her plan of taking everything away from him. She did that while pretending to still have the mentality of a child. She also wants to repay Ye Jun Qing back for everything he did for her while she was Yao Mo Xin. In the process of revenge, she met many people who will fall in love with her wit and intelligence.
