Glancing at the dark, bottomless end of the staircase, Lumian took out a mirror and activated the contract ability on his body.
He immediately sensed the imprint on the full-length mirror in the Tudor treasury, ready to dive into the mirror and traverse through at any moment.
Maintaining this sense, Lumian reminded Franca and Jenna, "Walk close to the sides later—very close."
From his experience, walking down the stairs this way would bring them into the reflection range of that full-length mirror.
For Beyonders of other pathways, they only needed to guard against being affected by the resulting illusions, scaring themselves crazy or to death. But if Hunters and Demonesses let their shadows be reflected on that full-length mirror, they might have their bodies snatched by the long-fallen Alista Tudor through pre-arranged setups, allowing Him to resurrect and return.
