Why did he say that? it was because in the history of the exiled Island, there was a place mentioned many times, the spirit world. At first glance, the spirit world seemed to have nothing to do with the sword spirit world and the demon spirit world. However, from the records of the spirit world on the exiled Island, it could be seen that the sword spirit world and the demon spirit world were only a part of the spirit world.
As for how big the spiritual realm was in ancient times, it was really hard to say, because there were no records in this area anymore.
However, this information alone was enough to make Zhao Hai and the others very happy. At the same time, they also learned that there were not many restrictions to entering the outer city. In fact, as long as you were strong enough, you could enter any city on the island. If you were not strong enough, you would be stopped in front of the city gate. It was not a person who would stop you, but an array.
