Washing Machine: There is only one truth, but why did I try so hard to figure out the identity of the murderer, but he committed suicide?This unscientific!
Black Carbon Edition Washing Machine: No matter how well-planned the criminals are, the criminals will not be the ones who have the last laugh, but why are there traces of other people's influence behind many murderers, but I can't find any useful clues at all?
Qiu Xing Qi Ye: Angels and Demons are just a thought!I'm not a detective, and I don't have that obligation to investigate the truth!I'm a little bit interested in creating truth.
