Previously, when Gu Jinxing, Hu Jiayao, and Huang Yan were looking for the secret laboratory behind the G-point, they discussed it in the guild chat group the whole time, and they also shared their real-time locations in the group.
So, even though Wen Nan didn't participate, he knew roughly where the horizontal location of the secret laboratory behind the G-point was, and also that it was between the 3rd and 4th floors of the headquarters building.
Therefore, when Guan Ailin led Wen Nan to the end of a certain hallway, he was genuinely surprised.
Wen Nan could be sure that the wall Guan Ailin was facing backed onto that secret laboratory, but they were not currently at the G-point on the 4th floor; they were on the 3rd floor, where Huang Yan discovered the new member, Zhang Tianzhou.
