Liang Yuan's Case Files

A socialite is murdered, and killings become frequent in a small city. Just as the detectives are at their wits' end, a boy claiming to be a detective slips past layer upon layer of checkpoints and quietly takes a seat on the chief inspector's desk, declaring that he can solve the case as long as the money is right.

The death of an old beggar by the roadside leads to the massacre of three families. In a run-down mansion, they even find a letter written fifty years ago to a boy living in the present day!

Time passes so quickly. When you meet again next time, will the person before you still be the friend you remember?
