After a car accident, a modern loving couple, Zhou Ying and Gu Chengrui, both transmigrated through space.

Zhou Ying became a jinx everyone despised and had difficulty getting a full meal.

Gu Chengrui became the son of a wealthy, cold, and violent family.

They hated him and were indifferent to his wife. With no one to love or care for the couple, they made a decision.

They decided to split up from the family!

They were penniless in their new house, which had nothing. But there’s nothing to be afraid of!

They had their interspace and wisdom to get rid of poverty and get rich in minutes! As the days started getting better, trouble came knocking on their door.

The family wanted them to go back to being their mule?

No way! The couple stood united and called them out on it, refusing to go back!

Their old rival, a father-daughter pair, wanted to steal their house?

The couple rolled up their sleeves and clashed with them head-on! After much difficulty, they finally had peace, but then a disaster that happens once every thousand years came…

For the once dead Hua Yu Man, she has to do three things this lifetime: kill those who harmed her, kill the man who said he loved her, and protect a place called “home.”

She seems docile and gentle, with the air and temperament of a beautiful young lady. But in fact her heart is cold, overbearing, and black belly, with a mysterious identity that can drive the world crazy.

He is the Thirteenth Prince, but also the country’s disgrace; a cold and ruthless man who doesn’t put human lives in his eyes. But only towards a sometimes gentle, sometimes willful and sometimes disobedient woman, would this man be ceaselessly doting and spoiling.
