"Not a single entity, yet the fierce ghosts don't affect each other... this is the first time I've seen something like this. Perhaps an individual fierce ghost isn't terrifying, but gathered together they produce a certain qualitative change."
Yang Jian stared at the other four fierce ghost shadows reflected on the ground and felt troubled.
He could use the Coffin Nail to pin down one shadow, but not five. So, to handle this situation, he had to understand how these fierce ghosts killed.
"The shadow of the first fierce ghost killed that Brother Long; at the time, the other four ghost shadows showed no anomalies, indicating that Brother Long matched the first fierce ghost's killing pattern."
