Yu Ziqing had never expected to encounter someone who hired assassins right here.
He roughly reconstructed the process in his mind. No.2, knowing that Su Li was about to return to report, and having a clear track of his movements, coupled with the limited time and possibly not having contacted No. 7, left a message.
Because it was apparent that their important intelligence exchanges were usually conducted face-to-face.
And for No. 7, killing Su Li was not a difficult task. Under normal circumstances, for the former No. 7, it was indeed a trivial matter.
In exchange for a piece of intelligence, that No. 7 couldn't have refused.
No. 2 probably never imagined that No. 7 would fail.
Afterwards, when No. 7 really did fail, this guy came to overwrite, covering all the previous messages.
And this guy probably didn't know that this wall could still display the covered content, people only saw it as a plain wall, not a real one.
