"Do you have a way to stop them?" Philip hurriedly asked Conrad through the window.
He recalled that Conrad had some powers that lure ghosts towards the mirror, making it look like they were exorcised.
However, he wasn't sure if they were effective towards spiritualists' spirit bodies. That was why he asked Conrad for clarification.
"I can only lure ghosts with lingering desires by promising to help them. But since our enemies are spiritualists who are still alive and with a clear goal in mind, I can't really do that." Conrad answered.
'Right,' Philip thought. When he was about to think of another solution, Conrad continued.
"But, if they come close to a mirror, I might forcibly pull them in." Conrad sighed and said, "However, it requires a lot of time and surely, the spiritualists would be wary of any mirrors."
