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!

- Description from Novelupdates

– The planet [Earth] has entered the abnormal state [Apocalypse].

– You have failed in saving the Earth. The Authority, [Vintage Clock (EX)] rewinds the world’s time.

For Yu Jitae, it was a message he had seen many times.

It was tiresome.

It would have been great had he died with everyone else.

But he couldn’t, for his authorities that made him the strongest existence, brought him back in time whenever he did.

And even with his strength, he couldn’t protect the broad earth against the maddened dragons.

– The world’s time will soon begin.

As the clock resumed ticking in the direction it should, his 7th iteration came to a start.

Fortunately, he finally had a gist.
