Scheme without scheming

Yu Dong's orders left Yu Sa's family in fear. They looked at her in shock and couldn't believe what she had said and done. She was actually telling a wild animal to bite them if they ran? How big was this coyote? Even if it only took a bite, they would lose an arm or leg. How could this woman be so cruel? 

"I will wait for you to come out," Yu Dong did not care what Yu Sa and her family thought about her. She coldly glanced at them and said to Yu Sa, "I will wait for another five minutes, if you are not out by then I will come back inside." 

With that, she turned around and walked out of the guest courtyard.
