The cloaked man had a brief conversation with Su Lun, got the information he wanted, and then left the apartment.
He didn't even take a look at the basement.
But it made sense, even knowing how to get in and out, it didn't mean one would definitely make it out alive.
Going down to the basement would inevitably involve him.
If he indeed encountered one of those advanced blue-skinned zombies, even though he was a top professional in Old Lington City, it wasn't certain that he would come out alive.
However, Su Lun was somewhat surprised by this uninvited guest.
The cloaked man had shown no hostility from beginning to end, like a true gentleman, polite, reasonable, and fair in dealing...
But why would such an apparently gentle vice-chancellor of the Black Tower Academy defect from the inner city?
The reason was probably what he said himself: knowing would invite trouble due to certain secrets.
