After Zhao Hai led the four of them into the room, he walked to the screen in front of the bed. He touched it with his hand, and the screen lit up. The icons appeared on the screen again.

Merlin and the others looked at the screen in surprise. To Zhao Hai, this was a very ordinary thing, but to Merlin and the others, this was simply too amazing.

Zhao Hai immediately tapped on the camera icon, and the 3D image of the castle appeared on the screen once again. Zhao Hai noticed that the green dots in the castle seemed to have decreased, especially in the main castle. There was no longer any Green Dot.

Zhao Hai clicked on the location of the inner castle's courtyard. There were still two green dots active there. The scene on the screen immediately changed to the courtyard of the inner castle.
