Zero

'Sister, you are really such a troublemaker'

He thought as he clicked on the screen again.

'Yes'

No matter what you do, we are always here to back you up, Sister.

'Well, even if you are a troublemaker. It's alright, I'll take care of all your mess.' He smiled with satisfaction as he looked at the blank screen before closing down.

The person sitting in front of the computer screen just now was none other than Chen Mo. 

Aside from his job in the office, he did personal work like this one today. And in the Dark Web, he was known as hacker 'Zero'. 

He always took the work after thinking it through, and despite his well known fame on the Web, he took very few cases after a long consideration. 

But today, it was definitely something else which made him attracted to this case.

Chen Mo felt as if someone placed a heavy stone in his heart after he received the message that day.
