Chapter 70: Hitting at Mo Ling!

At the same time, 

All the cases he has been working into, he couldn't solve any of them till now.

Especially the incident at the hall in which they didn't leave any trace was still completely in darkness.

Having no witness and the man who invaded getting killed by someone he doesn't even have any clues about, that was the worst part of this case.

The person who killed all of them without leaving any trace behind, it's already confirmed that he is a skilled professional who doesn't work in the pattern unlike the norms.

The person is a killer or must be an assassin in perfect disguise, who doesn't work outside often, meaning that he somehow must be connected with the Underworld. 

But it's frustrating the hell out of Mo Ling's mind.

Seriously, Chen Yu would've danced in joy if she were to know that she was wrecking Mo Ling's brain like that and he didn't even know!

But that was not the question right now…

Who could it have been?
