According to Sei Gasakai, the Ghost Parade covered many areas in the East Sea. Many places had large numbers of Yin-attribute dimensional creatures.
This was only the prelude to the Ghost Parade. When the true Calamity creature appeared, there were definitely more Yin-attribute dimensional creatures.
Zhou Wen didn't know much about the legends here. Sei Gasakai told him that if the Ghost Parade was the same as the legends, there would probably be hundreds of dimensional creatures like the Ghost Train.
As for the source of the Ghost Parade, Sei Gasakai wasn't too sure either. He only knew that a large number of Yin-attribute dimensional creatures had first appeared in the Ryukyu Islands. As for which dimensional zone had appeared first, Sei Gasakai wasn't too sure.
Zhou Wen planned on heading to the Ryukyu Islands to take a look before the Calamity creature appeared.
