"Master, what can I do for you?" Sebastian immediately bowed after turning around without looking.
However, he didn't hear a response for a long time.
"Did you come back to take me as your disciple again?" Sebastian said tentatively while glancing up.
The old man's blue, transparent figure was in front of him, just smiling at Sebastian.
However, just this smile caused a shiver down his spine as his hair stood up on end, almost like he was electrocuted.
"No, I am here just to collect the debt you owe me, with interest on it." The old man's smile widened, almost like a peaceful and happy smile. However, the terrifying pressure he emitted told another tale.
Ahh!
The loud, despairing scream of Sebastian echoed in the room.
However, for some reason, the sound was cancelled whenever it hit the wall in thin air, which caused it to only reverberate inside the room. While outside the house, not a sound passed.
