A Ghost Who Steals Luck

System Zhitian made a contract with Mu Yu, who has become a ghost. One system and one ghost work together. Zhi Tian is responsible for looking out and responding, while Mu Yu goes to various small worlds to steal luck. They specialize in selecting the kind of girl of destiny. They use the identity of a distant relative or an old friend or even an orphan of the girl's parents to go to the other party. They follow the ways of heaven and help the girl of destiny grow up. They can also gain the favor and luck of the girl of destiny. They even don't let go of the previous heroine whose luck is about to disappear. They try their best to suppress the other party and quickly weaken and steal the luck of the other party... But Muyu doesn't want to be a thief, and she can't be a bad person. Although she does like to get something for nothing, her three views are still very upright. Even if she occasionally has some dark thoughts in her heart, it's just a thought. But why can the Daughter of Destiny and the previous Daughter of Destiny hear her thoughts? Why didn't the previous Destiny's Daughter end well? Is the so-called destiny just a conspiracy?
