Lin Qiao put the gun back into her space, then walked to Liu Yu's body and dug out his energy nucleus. She wasn't going to let that scum live anyway, because he was as sick as Yang Jianhua, and was Yang Jianhua's loyal underling.
Lin Qiao clearly knew how he fantasied about her when she walked close to him.
Liu Yu had dark and sick thoughts, and was a coward. He bullied the weak and feared the strong; moreover, he liked to abuse women.
Lin Qiao used his fear and make him defuse the bomb. He did what she asked, and naively thought that she would let him live.
Lin Qiao put the boxes which were full of bombs into her space, then turned and left.
On the other side, Duan Juan and her people saved all the people who were hanging on the wall as baits. A small part of those people had died, but the rest were still alive.
