Fortunately for me, the Shadowed Blade Sect have quite a few techniques at their disposal for infiltration, and thanks to Elder Po, I know most of them. Karl has an area sleep spell, so he will go to the barracks first while I take the catwalks. We don't know where the four immortals will be when we arrive, so it's really up to chance just how much risk of exposure we will face.
With a bit of luck, one or two will be off shift and sleeping, but things rarely go that smoothly for us. I'm personally hoping there's one up on the walls, so I can eliminate him early before he can raise the alarm.
With the help of the locals, we manage to sneak within a kilometer of the compound and find a good hiding spot for Elder Song and Lelou. From that distance, they can reach us in under a minute if they're an emergency, but it's far enough away that they won't get spotted, even if they're not entirely masking their energy.
