Basically, the followers of the Sun Goddess in the south can't possibly be unaware of Su Li's deeds. As long as they go for militia training every week, attend church prayers, and offer sacrifices, they are bound to hear about some of Su Li's exploits. Among them, there are even many who are fanatical admirers of Su Li, repeatedly spreading Su Li's deeds to the surrounding crowds, and it is thanks to these people that many knights from other churches have heard of Su Li.
Among these people are also those with a pilgrim mindset who, upon hearing about the Radiant Competition Festival, immediately rush to Hesse Territory.
Basically, once these people arrive in Hesse Territory, they don't leave. Hilude only mentioned the problem of the large number of knights arriving, because she is currently the highest official in charge of security, and what she sees are the troubles that come with it.
