Ghost Coffin's ghosts cannot be imprisoned.
Because imprisoning a ghost will trigger its second ability, similar to a reboot. The ghost will discard its identity and reappear before you under another guise.
Yang Jian had already experienced this once in Huanggang Village, so he was crystal clear about this.
Since it could not be imprisoned, what he could do was to reduce the ghost's power, decreasing the number of ghosts it could suppress from nine to six.
Only by reducing the ghost's level of terror would Yang Jian dare to proceed with the next step of his plan.
The best way to reduce the number of ghosts it could suppress was to take away the Coffin Nail left in him by Wang Xiaoming.
As for why the target was that particular Coffin Nail.
There was only one reason.
