A son alive is better than dead

The Li family hated Yu Dong and the Yu family, they wanted to make use of Yu Le's identity as a mer and Li Sangyu's husband to make the Yu family submit to them but instead of agreeing with them, Yu Dong simply arched a brow and said, " And send my uncle for you all to kill? There is no need for so much nonsense, take out the dowry that you took. I have enough money to raise Uncle Le and his daughter for the rest of their lives." 

If you have the money then why are you ripping us off?  Are ten taels that big of a thing for you ?! 

Though the Li family scolded Yu Dong, they couldn't beat her up. Especially after seeing Li Sangyu being sent flying away when she somehow managed to summon her courage to attack Yu Dong. All it took was a flick of Yu Dong's arm and Li Sangyu broke open the wall of the thatched hut as she was sent flying.
