When he first crossed over, Chen Liguo did not want to accept it.

But he quickly discovered, after he crossed, he found that all the men he met had perfect figures and eight-packs. Furthermore, these men liked him.

As a gay man, Chen Liguo was so excited he shed tears of joy.

However, the world obviously wouldn’t have such good things.

System: Hehe

Gu Qingli, a modern-day doctor and poisoner, was killed by her best friend. She was reborn as a weak peasant girl who could easily be bullied. Not long after she returned home, her wedding was called off. Everyone in the village started speaking poorly about her. A greedy matchmaker showed up and tried to convince Qingli to marry an older man! The matchmaker had barely been gone for a few seconds before returning once again. It seemed that Xiao Laosan, a man from the same village who was famous for bringing bad luck to his partner, wanted Qingli as his wife. The matchmaker wondered why a wretched woman like her was so popular. Gu Qingli did not mind. She thought that she, a wretched woman, was a perfect match for this man. For the days to come, she'd take her younger brother with her to forage for herbs, and they'd stir up trouble when they got bored. Wretched woman? A failed investment? Those things had nothing to do with her!

This is an alternate history. Decades after the fall of the Eastern Jin Dynasty, the world is still in chaos, although there is hope for reunification.
