The grand and exciting Ghost Meeting ended with an anti-climax. Of course, to many people, this was just the beginning.
Right Sect obviously wouldn't submit to Left Sect simply because of the Ghost Killing Yama Order, they would certainly make a significant move next.
On the day they left the mountain range, the tens of thousands of people who had rushed to the Left Sect split into many groups.
Although the location of the Ghost Meeting was secret, the Righteous Path could not be unaware of it.
To put it bluntly, there might be spies from the Righteous Path within both sects, but both sects also have undercover agents among the Righteous Path. They both had well-informed sources, so the Righteous Path could never attack the two sects during the Ghost Meeting.
However, on the return journey, since the target was too big and the two sects could not coordinate all the time, they were likely to become targets of the martial world's Righteous Path.
