In the quiet deep of night, the Black Crow Sect lost an ordinary member, which didn't raise any alarm.
Or rather, the Black Crow Sect's residence was just like any common household. When Chen Mu returned, he still saw nothing unusual; it was all in pitch darkness without a candlelight in sight, nor any suspicious movements.
Chen Mu took another person out for questioning but still, he met with responses of ignorance. He then knew that most likely all the people living in this area were the same, and even if he questioned each one, there would probably be no one with information—perhaps those in the know were no longer here.
But.
From the second person, Chen Mu learned something; to these ordinary members of the Black Crow Sect, it was common for higher-ups, even Protectors and Vice Sect Hierarchs, to mysteriously vanish and reappear without warning.
