She married a driver she just met. However, the last thing that had ever come to her expectation was that her bridegroom was no other than the most mysterious billionaire in the city. This marriage brought her baby twins. Thus, she worked harder to support this family. She was the queen of the entertainment circle. When she met the king who dominated the business world, she finally knew her husband’s true identity.

Wan Tong was bound by the “Corpse Collecting System” and travelled through various small worlds. Her mission is to use the big boss’ white moonlight’s body to resurrect and stop raiders from looting the big boss’ luck.

Wan Tong : Didn’t you say that the big boss has no emotional line?

System : Who brought the white moonlight back to life →_→

Wan Tong : …. sob, sob, every day I try my best to help the boss deal with the raiders, but the boss is thinking about how to attack her!

PS :
(1) The male lead is the same person, the white moonlight is the original MC, which is mentioned later.
