Eerie Manor and Exorcist Hall possessed such remarkable effects.
This was because Wu Heng had used the bodies of Blood Floss monsters as nodes to transmit his domain over.
He then used his own power to sort through the earth's veins, extracting most of the "source seawater" scattered throughout the ground beneath each city and gathering it within a hundred meters of Eerie Manor and Exorcist Hall.
The sound of flowing water people had heard from beneath their feet at the time had actually been the sound of mobilizing those sources. Its flow did not truly exist; it acted upon the mind instead.
That dispersed "source seawater" already possessed a powerful restraining effect on evil ghosts. Now that it had been concentrated together, its suppressive force had instantly increased more than a hundredfold.
This was why Eerie Manor gained a stronger ability to suppress evil ghosts.
As for the bell in every Eerie Manor and Exorcist Hall, Wu Heng had used some Cursed Disciple-grade materials to fuse it with the buildings, evolving it into an item for collecting souls. Suppressing evil ghosts was merely a side effect of its ability to absorb source seawater.
It was like a warehouse used to store ghosts.
Yet that side effect of suppressing evil ghosts was precisely what the people of this world needed most.
Once the bell had received sufficient replenishment at Eerie Manor, it could be taken away for a period of time, unlike Eerie Manor, which could only remain stationed in one place.
However, Wu Heng's act of drawing upon the source seawater also caused future problems.
That was, apart from the hundred-meter radius around Eerie Manor and Exorcist Hall, the restraining force on ghosts throughout every city had drastically weakened.
Ordinary ghosts that would originally become bound as "earthbound spirits"
