Gu Ning said that because she was afraid that they might encounter an accident and be unable to come back soon.
If they were really in danger, Xu Jinchen and the others wouldn't be able to rescue them, so they shouldn't come in no matter what happens. They had to leave.
Gu Ning didn't think that she and Leng Shaoting would be injured. Even if they ran into trouble, they would get themselves out.
"What? You two are going in there? It's too dangerous!" Zi Beiying didn't think it was a good idea.
Xu Jinchen and Chen Meng understood Gu Ning and Leng Shaoting's worries, so they agreed. Even if they disagreed, it was useless. Therefore, Xu Jinchen and Chen Meng said, "Sure."
"You…" Zi Beiying couldn't believe her ears. How could Xu Jinchen and Chen Meng agree to let Gu Ning and Leng Shaoting go in without them? She was anxious and annoyed. She felt that they didn't care about Gu Ning and Leng Shaoting at all.
