Black Cold Wave

After a class reunion, Cheng Yiying was kidnapped. The person who kidnapped her was Gao Qiu, who was the most talked about at the class reunion. Gao Qiu killed someone six months ago, but was exempted from criminal punishment because he suffered from intermittent mental illness.

Gao Qiu is not only a psychopath and murderer, but also Cheng Yiying's ex-boyfriend. Gao Qiu didn't believe that he had killed someone, so he approached Cheng Yiying and asked Cheng Yiying to help him prove his innocence. However, Gao Qiu asked Cheng Yiying to help him prove his innocence, but he did not let her leave. She was imprisoned in a cold and damp room. Gao Qiu only gave her a mobile phone. Cheng Yiying must use this mobile phone that only Gao Qiu can use to overturn a murder case that has been settled! This is almost impossible to do. But for her own safety, Cheng Yiying had to cooperate with Gao Qiu. At the same time, she is also waiting for an opportunity to escape from the prison. But when the truth gradually emerged, Cheng Yiying discovered that the real prison had just fallen...
