Xiang four could almost imagine that one day, someone like uncle Xiang would accidentally enter the yulun illusionary realm, the rumored territory of the immortals, meet the descendants of these Dragon Slayers and mention the outside world.
When these soul Dominators learned that the world had forgotten about them and regarded the evil dragon's wreaking havoc as a legend, that the victims had actually worshipped the evil Black Dragon and used it as the tribe's totem, it would definitely have a huge impact on these people who were trapped in this area. It would cause their faith to collapse, and they would fall into the demonic realm.
This was not Xiang SI's casual guess. After all, Yi Chang had previously mentioned that they had a difficult attitude back then, which proved that this group of people were not calm and relaxed.
