That wasn't the only thing Jiaying was shocked about.
Not only did Luke wander around Afterlife, he also liked to chat up people.
Not only did he chat them up, he focused on the women.
The annoying thing was that Jiaying had instructed everyone to be on guard against Luke.
In the end, as Luke chatted with the women, they started shooting off their mouths.
It was like he was taking a census: how many people were there in Afterlife, how many had awakened superpowers, and so on.
If Luke continued asking like this, apart from the small amount of classified information in Jiaying's hands, he would have all the main information on Afterlife.
Jiaying had actually done a good job of keeping Afterlife a secret; for example, the common people definitely didn't know the abilities of the five people whom Luke had taken down, or how Inhumans were awakened, and so on.
