Gu Qingcheng nodded. "You are right. The rooms you and I went to were similar. There were some differences, however. I guess those must have been crystallizer items, but I didn't know that at the time. And when I actually returned from there, I was unable to find the entrance I had originally used."
Han Sen thought the sanctuaries definitely had some association with the crystallizers now. When he entered the Main Control Room, he himself had been taken ten years into the future. He had no reason to doubt what she was telling him.
But Han Sen still believed that something was amiss. He looked at Gu Qingcheng and said, "I remember something; weren't you a member of the seventh team? You were with Han Jinzhi in the beginning, and it's a well-known fact that humans were unable to enter the sanctuaries at that point. The teleporters were just for testing. Did you get out through one of those devices?"
