It was perfectly normal that they could recognize the two of them.
Unfortunately, Xu Xin and Xu Ying didn't have much time.
The main reason they were out walking the streets was to have Xu Xin use his mind-reading ability to check the people in the area, to see how many of them had issues, and what proportion of the crowd those people made up.
To attract the attention of the problematic ones, Xu Xin had even put on a wool cap with a lush World Tree painted on it.
People whose thoughts he couldn't read were obviously problematic.
And among those whose thoughts he could read, if anyone saw the World Tree symbol on his hat and certain thoughts popped up, that meant they were problematic too.
But all the way up to now, Xu Xin hadn't found anything wrong with the people around them.
That actually surprised him a little.
Xu Ying had said earlier that the underground world had been infiltrated; looking at it now, they clearly hadn't infiltrated all that much.
