The traitor Gu Mang returned to his home kingdom again. Everyone rejoiced in his banishment. It was said the one who hated him most was his closest friend – the cold and stoic Young Master Mo.

A rumour: Young Master Mo prepared three hundred and sixty-five methods of torture to try on Gu Mang, enough to play with him for a year without repetition.

Xu Shiyan was reborn back to forty years ago, the second day of his wedding.

Shui Lingling’s daughter-in-law has just entered the house, and everything is off to the best start.

Farming, hunting, going to the mountains to dig a big ginseng, life in the 1970s was actually quite good.

I didn’t have much skill in my previous life, and I don’t have any grand wishes in this life. I just want to live a good life with my daughter-in-law and cultivate my daughter into a talent.

The eldest daughter likes to write, so let her take the Chinese department of a key university.

The second daughter likes to sing and dance, and the art school is good.

As for that bastard son, the prodigal son, he didn’t have a chance to stuff it back into his mother’s belly in his previous life, so he just wanted to be born in this life.

But why are some things different?
