Cloak and Dagger Hall

While the Treasury Minister's residence was indeed near the edge of the grounds, Lin Mu didn't expect for the assassins to be hiding so near to it.

Lin Mu spread his immortal sense and observed the distance between the two locations, finding it to be barely three kilometers apart.

"Three kilometers… they managed to hide all this time with such a small distance and even avoided the Immortal Sense of others." Lin Mu hadn't expected them to be this covert.

While Immortals didn't usually scan underground, in high security areas like the Imperial Grounds, it would certainly be done to check for anything suspicious. Lin Mu had even read about an assassin a few hundred years ago in the past where the assassin had hid basically buried himself underground when some landscaping work was being done.

He had stayed hidden for several months before finally striking out when his target was passing over the place he was buried in.
