How many of them were there? What was their purpose? Were they awakened? What did the other world look like?
Fei Yuhan had no idea.
From what she saw now, they were at least not enemies. Roland had indeed killed a lot of Fallen Evils and was truly fighting against the Erosion.
The joint mission last time provided the best example. She would never forget that someone had said "Your Majesty, everyone has been knocked out" before she had lost her consciousness. She had obviously noticed that Roland was dodging her, which further confirmed her suspicion.
In other words, if these people harbored ill designs, she would not have been still alive. Roland could have killed her after he had exterminated the magic creature and had the magic creature take all the blame. Nobody would have ever suspected his version of the story.
Fei Yuhan thus believed that Roland was helping this world.
