Maybe it was because she was confident in her ability; or perhaps it was some smug type with self-appraisal. The woman who called herself 'Sis Shuang' told Zhao Yu the truth about Qu Ping's death.
Yet again, Zhao Yu couldn't believe that the murderer that had killed Team Leader Qu Ping was dead! The person had been no other than Zhao Qing, the one who had jumped off the building because of Zhao Yu and Miao Ying!!
To make Qu Ping's death look like an accident, they had found a scapegoat, Hou Meng, a long time ago. Then, they put Qu Ping and Hou Meng's cars under close surveillance. Meanwhile, they made arrangements at Jin Jiang Road to make sure there would be no surveillance of the area, making it easy to attack Qu Ping.
