"The Abyss Demons Are Out"
Of course, the majority of the idle shamans only got the most superficial information related to these people's history when they were still alive, but some who had various unknown purposes or were hackers got shocking news one after another.
They didn't expect the souls trapped inside the seal to have identities more than just what was written on the surface.
Although these hackers and various interested people didn't know about transmigrators, they all found out that those souls were not the souls of ancient heroes who first created the seal at all.
The surface identities of these people alone showed that they were not the ancient heroes and they were all newer heroes in the past hundreds of years, not thousands of years.
This means the seal actually consumed the souls of people who were not involved in the making of the seal at all.
What does this indicate?
The seal required sacrifices!
