Roan himself had never seen weapon intent, nor had he heard about it. He found it by himself and then passed it to Rean by sharing his experiences with their connection. Roan was responsible for combat, while Rean was responsible for finances. It had always been like that. In any case, it was thanks to this connection that Rean could experience what a weapon intent was and give birth to his own sword intent sometime later.
However, such a thing was impossible to do with Luan. Roan had no connection with him. Even Kentucky and Celis wouldn't work since their connection was only cultivation-related. The system's cultivation upgrades, for example, were exactly this type of relation.
"All I can do is share my experiences by mouth, trying to explain how I got to know and use weapon intents. However, Rean can be my witness that everyone understands a weapon's intent in their own way," Roan explained.
