Perfect criminal
In the Republic of China, there was a crime-solving genius known as the "Super Detective" who solved countless cases in his life.
When he was about to retire, he received a letter of challenge signed as "The First Detective of the Republic of China", who threatened to commit three cases that he could never solve.
Facing the ensuing bizarre murders, he gradually discovered that the murderer seemed to know the truth about an unjust case that year.
And when he finally found out who was behind the scenes, he was shocked to find that the man was his mentor who had been dead for many years.
