He found out that he is in a world similar to our own with a timeline akin to early twentieth century.

A fair complexion can conceal three shortcomings, but being overweight can ruin everything. Gu Yi doesn't look bad, but her round plump figure always attracts strange looks from people. In her previous life, her marriage was mediocre, but in this new life, even as a plump woman, Gu Yi is determined to rise up!

Everyone in the entire imperial capital city B knows that, in recent months, there has been a fortune-telling stall with a sky-high pedigree.
Break the marriage, control the universe; talk about misfortune and good fortune, test the secrets of the sky; comment on the eight characters, change the way of luck… simply say that you are alive, you will not die, say that you are dead, you don’t want to live!
The reason why anyone with a head and a face knows it is because the head and face naturally feel that the magic stick cannot be placed on the table and cannot be seen.
However, the wind has changed recently. It is said that the famous Bai family of the Junhong family has sought a famous magic stick for the youngest son of the sick jar!
Unexpectedly, the magic stick was very pretentious and deadly, and only said one sentence.
“I miss him, unless I marry him. Otherwise, within three months, he will surely die!”
So, the whole emperor was in an uproar.
