After her short meeting with Zhao Yu, Miao Ying drove towards the Gao Lanqi police station to investigate the case. She would return to the cottage that night.
Taking advantage of the free time, Zhao Yu finally used some the points he had earned and transferred the recordings from his Invisible Recorder to his laptop. Those recordings could be used as evidence to bring the investors to court. Not only had they benefitted from Jiang Ke's crimes, but some were even involved in murder, amongst other illegal activities. Those people were the scum of society and had to be locked away.
To reduce the chance of implicating himself, Zhao Yu erased parts of the recording containing things he had said when he was imitating Jiang Ke. If Jiang Ke woke up, he would definitely not admit to what happened in the night club and the words 'he' had said. As such, Zhao Yu tried to cut those parts of the audio out.
