"Do you know about Tu Yuan Country?"
Xin Lin asked in return.
"I know a bit. My third brother has been to Tu Yuan Country. It's a frontier sovereign state. Although its population isn't large, it's very strong, with formidable military strength equivalent to ten Longteng Countries. That's why I'm curious about how you got involved with them."
Murong Ziyue said, half puzzled and half concerned.
"Speaking of it, I was just about to ask you, what is a sovereign state and what is a vassal state? I've heard you mention them many times, but I'm not sure what they actually mean."
Xin Lin had heard people mention 'sovereign state' several times.
However, she'd searched through various books and those from Qingtian Academy, but found no relevant information.
